COVID-19 PROLOGUE
The Integrated Solid Waste Management Plan Update 2019 process began in March of 2018. Early in
2020, just as the document was being finalized, Covid-19 made its appearance in the County of Hawai’i.
The administration quickly enacted emergency protocols. Among everything else, solid waste
operations have been and continue to be affected. This Plan represents the County’s Update pre-Covid.
In that some of the sites, locations, and services may still be affected at the time this Plan is adopted,
please check our website at www.HawaiiZeroWaste.org or contact the Solid Waste Division at 961-8270
to obtain current information.
2019 Integrated Solid Waste Management Plan Update
County of Hawaiʻi
August 2020 ES-1
EXECUTIVE SUMMARY
ES.1 Introduction
The County of Hawai’i, in accordance with the Hawaiʻi Revised Statutes
Chapter 342G (HRS 342G), has completed its review, revisions, and
updates for the 2019 Integrated Solid Waste Management Plan (Plan).
Work on this update began in the spring of 2018. The Plan development
process involved monthly meetings that engaged both the Solid Waste
Advisory Committee (SWAC) and the County of Hawai’i (County) Solid
Waste Division (SWD) of the Department of Environmental Management
(DEM). The last update of the Plan was produced in 2009.
The Plan update evaluates solid waste management in the County, including waste reduction practices
and programs, opportunities for recycling, implementation of zero waste policies and practices, the
status of active and closed landfills, and options for increasing landfill diversion. The results are organized
by chapter in accordance with HRS 342G. Each chapter contains a summary of the 2009 Integrated Solid
Waste Management Plan (ISWMP) recommendations and the status of those recommendations, a
description of the existing conditions, a discussion of options available to the County to improve the solid
waste management program, and recommendations to implement selected options.
ES.2 The Path to Zero Waste
In December 2007, the County Council adopted Resolution 356-07 to “embrace and adopt the principles
of zero waste as a long-term goal for Hawaiʻi County” and the County subsequently developed a Zero
Waste Implementation Plan in 2008 that outlines suggested changes to solid waste management
(County of Hawaiʻi 2009a). The zero waste philosophy promotes the efficient use of materials to
eliminate waste and pollution by emphasizing a closed-loop system of production and consumption, and
moving in logical increments toward the goal of zero waste.
As stated in Resolution 356-07, the County of Hawaiʻi recognizes “that zero waste is a long-term goal
and that in the interim, programs may need to be implemented that may be counter to the zero waste
philosophy and are necessary to reach the long-term goal of zero waste and that such programs should
not be prohibited by the embracing and adoption of the long-term goal of zero waste.” To this end, the
components of the Zero Waste Implementation Plan, which can be realistically achieved during the life
span of this Plan, have been incorporated into the Plan.
The County will continue to take incremental steps toward achieving zero waste in the long term with
the understanding that the ability to truly achieve zero waste is realistically challenging for an island.
ES.3 Plan Update Process
Development of this Plan update was guided by a seven-member SWAC, appointed by the Mayor.
SWAC members participated in 13 meetings at which they toured solid waste facilities on both sides of
the island, reviewed draft Plan chapters, debated key issues, developed plan goals (provided in
Chapter 1), and shaped recommendations. Input was requested from the public during the preparation
of the updated Plan in a variety of forums including monthly SWAC meetings; routine posting of all draft
documents, agendas, and meeting minutes to the County’s online records archive; and two informal
2019 Integrated Solid Waste Management Plan Update
County of Hawaiʻi
ES-2 August 2020
public informational meetings. Following review and comment by the State of Hawaiʻi Department of
Health (HDOH), the proposed Plan was made available for public review for 60 days, which included two
public hearings. Appendix A includes the meeting minutes from the monthly SWAC meetings held during
the Plan update process, and Appendix G includes the draft Plan public comments and responses.
The key recommendations included in this Plan update have consensus support from the SWAC and are
intended to balance the many interests of the various stakeholders within the County. The County has
taken the top recommendations developed during this process, and will keep the stakeholders in mind
as the recommendations are implemented. This Plan update includes individual chapters that cover
various waste management topics as stipulated in HRS 342G. It includes responses to comments
received from the HDOH and the public. The Plan was submitted by the Mayor to the County Council for
adoption. Final approval by HDOH is anticipated by the last quarter of 2020.
A summary of the Plan recommendations is presented below.
ES.4 Chronology of Plan Updates
The County’s initial Plan, as required by state law (HRS 342G) was adopted on October 5, 1994. Updates to
the original plan were completed by the County and approved by the State of Hawaiʻi in 2002 and 2009.
2002 Plan
A key issue addressed in the 2002 plan update was the pending closure of the South Hilo Sanitary
Landfill (SHSL), which was expected to reach capacity in the summer of 2004. The 2002 update included
the following key recommendations:
•Construct no new landfills in East Hawai`i.
•Emphasize the recovery of recyclable materials at the planned East Hawaiʻi Regional Sort Station
(EHRSS), possibly by incorporating features of a material recovery facility (MRF).
•Procure a waste reduction facility for the East Hawaiʻi waste stream using either waste- to-
energy, thermal gasification, or anaerobic digestion technology. (See Appendix E for a
chronology of waste reduction study and procurement activities in Hawaiʻi County.)
•Establish a County recycling program with a long list of elements that have the potential to
increase waste diversion significantly.
After adopting the 2002 ISWMP update, the County took steps toward implementing these
recommendations, as follows:
•Expanded the number and scope of its recycling programs, which increased its recycling rate
from 15 percent in FY 01-02 to 29 percent in FY 07-08.
•Initiated development of elements of the EHRSS that could potentially serve a number of
strategic waste management functions.
•Issued two requests for proposals (RFPs) for construction of a waste reduction facility. The first
RFP was cancelled by the County. The second procurement process resulted in a proposal for a
230-ton-per-day mass-burn waste-to-energy facility to be located at the SHSL. In 2008, the
County Council rejected the recommended proposal, in part because the construction and
operation costs were higher than anticipated.
2019 Integrated Solid Waste Management Plan Update
County of Hawaiʻi
August 2020 ES-3
Since 2006, the County has taken three other important actions related to its solid waste management
system:
1.Completed a comprehensive engineering evaluation of its 21 recycling and transfer stations. This
evaluation concluded that 13 have serious failures requiring reconstruction to correct and
another six have serious problems that could be corrected without complete reconstruction.
2.Extended the capacity of the SHSL through sliver fill—an innovative engineering solution to
gaining and utilizing additional airspace. The County also implemented a comprehensive
compaction program.
3.Prepared an expansion feasibility study and capital cost estimate to assess whether undertaking a
7-acre landfill expansion immediately adjacent to the SHSL would be less expensive than long-
hauling waste to the County’s West Hawaiʻi Sanitary Landfill (WHSL) in Pu`uanahulu. The feasibility
study did not support the 7-acre expansion and this option was removed from further consideration.
2009 Plan
In 2009, the key focus of the Plan update was evaluating a series of potential options for managing
residuals that remain after source reduction, reuse, and recycling. After SWAC and stakeholder
consideration of potential options, the 2009 Plan recommended the following residuals management
strategy:
•Conduct a series of activities necessary to confirm the feasibility and cost-effectiveness of
undertaking development of a new landfill within the quarry adjacent to the SHSL site.
•Reassess trucking waste to the WHSL site including further analysis of consolidating waste at the
EHRSS and associated hauling operations, haul routes, traffic issues, and equipment acquisition
plans.
•Avoid issuance of RFPs for waste reduction technology during the Plan’s 5-year life cycle. During
each subsequent solid waste management plan review period, evaluate whether new
technology advances or other circumstances have occurred to warrant issuing an RFP for a
conversion technology for part, or all, of the County residuals management stream.
In addition to activities associated with handling residual wastes, the 2009 Plan presented a series of
recommendations regarding next steps on the path to zero waste, including expanded programs
targeted toward reducing the volume of landfill-bound waste and improving existing infrastructure. The
Plan also recommended reconstructing and upgrading one or more County recycling and transfer
stations each year.
After adopting the 2009 Plan, the County made many key decisions that will drive the functioning of
waste management on the island for years to come, notably the decision to truck waste (residuals) to
WHSL through the EHRSS (implemented in 2019). Other decisions and actions that will have a lasting
impact on waste management and diversion include:
•Constructed two green waste facilities—one in Hilo on the east side of the island, and one
adjacent to the WHSL on the west side of the island.
•Constructed seven new reuse centers located at the County recycling and transfer stations.
•Planned a compost facility to process more than green waste (and wood pallets). The new
facility will process food waste, paper, and compostable plastics (planned operation 2020).
•Performed major upgrades to seven recycling and transfer stations—the upgraded facilities are
expected to operate sufficiently through 2029. The County is also in the process of constructing
2019 Integrated Solid Waste Management Plan Update
County of Hawaiʻi
ES-4 August 2020
a permanent recycling and transfer station in Ocean View. Although great progress has been
made, the need to improve facilities with major engineering deficiencies still remains.
2019 Plan
With the closure of SHSL and the shipment of residuals to WHSL, the current deteriorating global
recycling market, new facilities (reuse and compost facilities), and fiscal concerns, this Plan update
focuses on waste diversion, with an emphasis on education, outreach, and public awareness. Outside of
maintaining or improving existing facilities, this Plan does not generally recommend the construction of
costly new facilities or operations. Instead, the County will assess how the existing facilities and
programs are functioning followed by a study to identify a solution that best suits the current and
projected future conditions. This includes seeking joint solutions with state and other Hawaiian
jurisdictions. For example, with the current market for plastics, the County has eliminated all plastics
(except for qualifying deposit beverage containers) from the recycling program. If the County were to
coordinate and negotiate with the City and County of Honolulu, there may be a temporary solution that
keeps these formerly recyclable materials out of the landfill until market conditions change.
ES.5 Consequences of Inaction
This Plan update outlines a series of options for the County during the next 10-year implementation
period. Some of these programs may be challenging and perhaps even controversial because they
require changes to ingrained behaviors and increased costs. The status quo is not sustainable for a
variety of reasons—notably market conditions, aging infrastructure, fiscal responsibilities, and
environmental impacts. Some consequences of inaction would include the following:
•The County’s recycling and transfer stations would continue to deteriorate resulting in reduced
service and potential public safety concerns.
•No further progress would be made in providing additional waste reduction, recycling, or reuse
services that are desired by many County residents.
•No significant progress would be made in further reducing waste sent to the WHSL, thus
resulting in a missed opportunity to reduce greenhouse gas emissions and reduce the toxicity of
waste materials sent to the County’s sole landfill.
•The WHSL would fill up faster.
The County’s proposed strategy of incrementally pursuing waste reduction and diversion with continued
local landfilling of residuals will result in decisions that best serve the needs for generations to come.
ES.6 Summary of Recommendations
The primary purpose of the Plan is to develop waste management strategies through the period of 2019
to 2029. The County developed these through careful consideration by the County’s SWAC, which
comprises representatives from various stakeholders. In total, 84 recommendations covering nine solid
waste management programs were identified.
The SWAC categorized 83 recommendations (and supporting implementation strategies) as high,
moderate, or low to provide the County DEM feedback on the solid waste planning initiatives that are
important to them as representatives of the community. [Note: One recommendation was added in
response to a comment provided during the public hearing process and was not rated.]
2019 Integrated Solid Waste Management Plan Update
County of Hawaiʻi
August 2020 ES-5
Table ES-1 summarizes the recommended measures and ranking of importance for managing solid
waste in Hawaiʻi County. Considerations for ranking the individual measures included:
Diversion Potential—What is the tonnage diversion potential from landfill?
Local Authority—How much control must the local government exert over the disposal management
system (e.g., service providers, infrastructure collection/transfer/disposal, and/or waste generators)?
•Implied—indirectly through culture or practice: less likely to accomplish measure.
•Influenced—by policy, permit, license or ordinance: moderately likely to accomplish measure.
•Explicit—directly through contracts or operations: highly likely to accomplish measure.
Receptivity—What is the relative ease and level of effort to initiate and obtain local buy-in? For
example, does it involve promotional activities, recognition, no requirements on waste generators,
minor costs (generally easier)? Or does it involve setting mandatory requirements, restrictions, or higher
costs (generally more difficult)?
Environmental Outcome—What is the environmental effect? For example, does the measure consider
ecological toxicity, human heath, or greenhouse gas emissions generated by raw materials extraction
and product manufacturing?
Staff Knowledge—How much staff knowledge or specific expertise is needed to implement the
measure? Can it be implemented by mid-level local agency staff without outside legal or contractor
assistance?
Community-Led Initiatives—How easy or hard is it for individuals or groups to adopt or implement the
measure without actions required by the jurisdiction? Can a local nonprofit or group of interested
residents carry out the activity (e.g., develop a “how-to guide”) or will it require initiation by local
jurisdiction staff or elected bodies (e.g., adopt a local ordinance)?
Outcome of Recommendation Prioritization
Ultimately, most of the recommendations and supporting implementation strategies were ranked as
moderate (45), followed by high (37), with only one recommendation identified as low. This
demonstrates that representative SWAC members agree that most of these actions are attainable and
can improve the County’s existing solid waste management program.
To further prioritize, each SWAC member was tasked to identify their top five recommendations or
themes. Recommendations that received a number one ranking were weighted (scored) higher than
those that received a number five ranking. Additionally, because some of the recommendations are
thematically similar, they were combined. Of the 83 recommendations, six recommendations or themes
were identified by more than one SWAC member as priorities. The top six recommendations identified
by the SWAC are:
•Conduct education, outreach, and public awareness – multiple recommendations.
•Regularly review and, when appropriate, renegotiate WHSL contract – Chapter 10,
Recommendation 2.
•Conduct additional household hazardous waste (HHW) collection events – Chapter 6,
Recommendation 5.
•Change County code to allow small businesses to drop off recyclables at recycling and transfer
stations – Chapter 8, Recommendation 5.

2019 Integrated Solid Waste Management Plan Update
County of Hawaiʻi
August 2020 1-1
1.INTRODUCTION
This update to the County of Hawaiʻi Integrated Solid Waste Management Plan (the Plan) presents the
County’s existing waste management practices and programs, explores opportunities for
implementation of waste diversion policies and practices, and outlines potential options and
recommendations for improving the waste management program. The Plan also presents information
on the status of active and closed landfills, historical information regarding the County’s evaluation of
waste reduction technology alternatives during the past decade, and closure of South Hilo Sanitary
Landfill (SHSL) and the transition to solid waste disposal wholly at the West Hawaiʻi Sanitary Landfill
(WHSL). The County of Hawaiʻi (the County) produced this Plan in accordance with the requirements of
Hawaiʻi Revised Statutes Chapter 342G (HRS 342G).
The information in the Plan is organized by chapter according to HRS 342G. Each chapter contains a brief
summary of the previous plan’s recommendations and a summary of their implementation status, a
description of the County’s existing waste management practices and conditions, a description of
options available to the County for improvement of the waste management program, and
recommendations for implementation for the next 10-years.
Development of this Plan update was guided by an 8-member Solid Waste Advisory Committee (SWAC),
appointed by the Mayor. SWAC members participated in 14 meetings that involved review of the draft
Plan chapters, debate of key issues, and development of plan goals and recommendations. In addition,
input was requested from the public in a variety of forums including monthly SWAC meetings; routine
posting of all draft documents, agendas, and meeting minutes to the County’s online records archive;
and two public hearings and the public comment period to the draft Plan. Appendix A includes the
meeting minutes from the monthly SWAC meetings held during the Plan update process.
The key recommendations included in this Plan update have consensus support from the SWAC and are
intended to balance the many interests of the various stakeholders within the County. This Plan update
includes individual chapters that cover various waste management topics as stipulated in HRS 342G. It
also includes responses to comments received from the State of Hawaiʻi Department of Health (HDOH)
and the public (Appendix G) through the draft review process. It was adopted by the County Council on
X, X, XXX and received final approval by HDOH on X, X, XXXX.
1.1 Goals of the Solid Waste Management Plan Update
This Plan presents not only recommendations, it also presents a vision for solid waste management
within the County for the next few decades. Consideration was given to the current state of waste
management technology in the United States and internationally, the history of waste management
practices in the County, and an assessment of successful waste management practices in other
jurisdictions. The objective was to develop County-wide solutions that consider the desires of the many
stakeholders, while balancing the fiscal realities of implementing the selected programs. It was
recognized that selected programs must be both implementable and sustainable to be successful.
The following goal statement and the goals that follow were developed during a series of meetings and
adopted unanimously by members of the County’s SWAC.
“The people of the County of Hawaiʻi understand they are a part of the global
community and can create a model for others. They value the environment, healthy
social relationships, fiscal prudence, and long-term goals coupled with specific, local
accomplishments. The following long-term goals will guide us as we develop an
implementable Plan.”
2019 Integrated Solid Waste Management Plan Update
County of Hawaiʻi
1-2 August 2020
The goals presented below were used to guide the development of waste management options and the
resulting recommendations of this Plan update.
•Sustainability. To ensure that programs and actions meet the environmental, economic, and
social equity needs of the present without compromising the ability of future generations to
meet their own needs.
•Increase Landfill Diversion. The County views waste as an inefficient use of resources, and seeks
to lessen discards to landfills by reducing waste, reusing (and repairing) still good stuff, and
recycling/composting by all County residents, visitors, businesses, and institutions.
•Efficient and Affordable. To balance funds available for managing solid waste with other County
priorities, the Plan identifies programs that get the best value (“bang for the buck”) for County
ratepayers and taxpayers.
•Minimize Environmental Impacts. To improve the environment and reduce greenhouse gas
emissions, the Plan emphasizes transportation efficiencies, supports material reuse and
recycling, and minimizes organic materials sent to the landfill.
•Litter-free. To eliminate illegal dumping on public and private lands, the Plan includes
legislation, education, and outreach programs.
•Sound Finances with Appropriate Incentives. To include financial incentives that will increase
landfill diversion, such as pay-as-you-throw (PAYT), while ensuring that the Solid Waste Division
(SWD) has enough funds to pay for the services it provides.
•Customer Service. To share aloha as well as information.
The goals listed above are intended to support all aspects of Plan implementation, including the
following:
•Policy. In County legislation and support for state legislation.
•Funding. Move towards diversifying funding sources.
•Operations. Reuse and recycling, household hazardous waste collection, residuals management,
recycling and transfer stations, and special events.
•Regulatory/Legal. Consistency and compliance with all federal, state, and County requirements.
•Education and Outreach. For County employees, residents, visitors, businesses, and institutions.
•Management and Employee Safety. Working in partnership with the United Public Workers
Union and the Hawaiʻi Government Employees Association.
The County acknowledges that the updates to this Plan could be challenging and will require a
significant amount of public education and stakeholder participation to be successful. The integrated
approach to solid waste management utilized by the County, the SWAC, and all contributors address the
overarching waste management goals of the community. The County will continue to foster
collaboration among the stakeholders for the implementation and ultimate success of the Plan.
1.2 Plan Implementation
With uncertainties regarding the recycling market, and the outcome of programs planned for operation
early in the planning period, as described in Chapter 10, the County would:
1.Continue the current system of funding most operating expenditures using property taxes and
tip fees in the near term.
2019 Integrated Solid Waste Management Plan Update
County of Hawaiʻi
August 2020 1-3
2.Study new funding strategies (e.g., PAYT, Enterprise Fund) to assess market fluctuations and
uncertainties, and to achieve less reliance on the general fund as aligned with Plan
recommendations.
3.Continue to fund major capital expenditures through general obligation bonds.
An initial draft Plan was distributed to stakeholders in December 2018 for comment, and a final draft
was made available to the public for a 60-day public comment period from December 6, 2019, through
February 4, 2020. The draft plan was then modified based on subsequent meetings with the SWAC and
key staff; comments received from HDOH; comments received at public hearings held in Hilo on
January 21, 2020, and Kailua-Kona on January 23, 2020; and written comments received during the
2-month public comment period. Comments and responses are included in Appendix G.
1.3 Organization of this Plan
This Plan is organized into the chapters listed below. Each chapter contains a summary of the existing
conditions and waste management practices related to the specific topic covered, potential issues or
concerns, and options that the County may consider to improve the program. Each chapter concludes
with recommendations for implementation during the next 10 years.
•Chapter 2: Waste Stream Assessment. Provides an assessment of the County waste stream
including background information about population and employment; historical and forecast
waste generation, recycling, and disposal; and information about waste composition.
•Chapter 3: Source Reduction. Discusses existing source reduction activities within the County,
identifies current issues and concerns with respect to current source reduction practices, and
presents options and recommendations for achieving further source reduction.
•Chapter 4: Recycling, Bioconversion, and Markets. Describes existing recycling and
bioconversion activities within the County; identifies current issues and concerns with respect to
current recycling, bioconversion, and marketing practices; and presents options and
recommendations for achieving the County’s recycling and bioconversion goals.
•Chapter 5: Public Education and Information. Discusses existing public education activities
within the County, identifies current issues and concerns with respect to public education, and
presents options and recommendations that will help enhance educational opportunities.
•Chapter 6: Household Hazardous Waste and Electronic Waste. Describes the current status of
the household hazardous waste (HHW) and electronic waste (e-waste) collection and disposal

2.WASTE STREAM ASSESSMENT
2.1 Introduction
This chapter assesses the County waste stream, including background information about population and
employment, historical and forecast waste generation, recycling, disposal, waste stream projections, as
well as information about waste composition.
2.2 Population and Employment
This section provides historical and forecast information about population and employment in the
County. These variables, along with other factors such as increases in tourism and construction activity,
are elements that contribute to increases in waste generation within the County.
Historical resident and de facto population for the County is shown in Exhibit 2-1. The de facto
population is a measure used by the State of Hawaiʻi to account for the effects of tourism 1. As shown,
the resident population of Hawaiʻi was 198,449 in 2016. The average annual resident growth has
decreased since 2000, with a peak average annual growth of 2.8 percent between 2000 and 2005 to a
more modest growth between 2010 and 2015 (1.2 percent). The ratio of de facto versus resident
population has remained consistent through the years.

and Table 1.09 De Facto Population, by County: 2000 to 2016.
Exhibit 2-2 provides a forecast of Hawaiʻi resident population growth through the year 2040 in each of
the County’s nine council districts, and summaries for West Hawaiʻi and East Hawaiʻi. As shown, future
population growth is projected to be slow. This is also the same for the de facto population estimates,
which are projected to exceed resident population growth at a rate of 1.6 percent compared to
1.3 percent annual growth through 2020, and then is expected to follow the same growth rate
thereafter (through 2040).
1 De facto population is defined as the number of persons physically present in an area, regardless of military
status or usual place of residence. It includes visitors present but excludes residents temporarily absent.

2.3 Generation, Disposal, and Recycling
2.3.1 Historical
Historical generation, recycling, and disposal for the County, and the resulting diversion rates are shown
in Exhibits 2-5 and 2-6. Generation is the sum of recycling and disposal. As shown, since estimated fiscal
year (FY)2 2009–10, both recycling and disposal in the County have changed substantially. Recycling
tonnage reported to the County by local businesses and the amount of recyclables managed by the
County decreased from a 36.1 percent diversion rate in FY 2009–10 to 20.8 percent in FY 2017–18, and
disposal increased from 155,682 tons to 224,196 tons over the same period. Review of the County’s
annual solid waste disposal summaries dating back to FY 2009–10 shows a decrease in metal recycling
starting in FY 2012–13. The County-contracted scrap metal recycling facilities were required to remove
their stockpiles prior to permit expiration. With the facilities no longer in operation, the County limited
the scrap metal they would accept and diverted scrap metal to the private sector; thus, there is a
marked decrease in subsidized scrap metal recycling following FY 2012–13. For example, in FY 2014–15,
County data show 5,757 tons of scrap metal recycled, which is 10.0 percent of the total recycling/
diversion tonnage. In comparison, County data show 35,240 tons or 39.0 percent of the total volume
diverted or recycled in FY 2011–12. Although there appears to have been a decrease in the recycling and
diversion rates, this number is skewed because the County began sending most of the scrap metal
recycling to the private sector starting in 2013. Finally, Exhibits 2-5 and 2-6 do not account for non-
County-sponsored (private) recycling or diversions. These could include big-box stores (e.g., Costco,
Walmart) that ship combined bales of cardboard and plastic to either the West Coast to third-party
brokers or to the retailer’s distribution center. Contractors or nonprofit groups also sell recycled
materials directly to brokers on the mainland.

Exhibit 2-6. Historical Generation, Recycling, and Disposal for Hawaiʻi County
Exhibit 2-7 provides a breakdown of total waste discarded at County recycling and transfer stations and
total commercial waste delivered directly to landfills between FY 2009–10 and FY 2017–18 for West and
East Hawaiʻi. As shown, disposal at recycling and transfer stations has grown faster in West Hawaiʻi
(approximately 35 percent) than in East Hawaiʻi (approximately 12 percent) during this period.
Commercial disposal has increased substantially over the past 9 years, experiencing percent change of
approximately 83 percent in West Hawaiʻi and approximately 19 percent in East Hawaiʻi. Commercial
waste comprises approximately 59 percent, while waste from recycling and transfer stations comprise
approximately 41 percent of the total disposed waste County-wide. Commercial waste accounts for a
much larger share of the total waste sent to landfill in West Hawaiʻi (approximately 70 percent) than in
East Hawaiʻi (approximately 48 percent).

Starting in 2009, the County resident and de facto population has shown a decrease in both generation
and disposal compared to previous planning cycle. As reported in the 2009 Plan, the 2007-8 resident and
de facto population of the County generated 9.4 pounds and 8.3 pounds of solid waste per capita per
day, and landfilled 6.3 pounds and 5.8 pounds per capita per day respectively. Using the same
methodology as the 2009 Plan3, comparatively, 2016-17 waste generation dropped to 7.1 pounds and
6.4 pounds per capita per day and waste disposal dropped to 5.4 pounds and 4.8 pounds per capita per
day for respective resident and de facto populations. Historical generation in tons, resident and de facto
population, and pounds per capita per day are presented in Exhibit 2-8.
The reduction in pounds per day could be attributed to the County’s adoption of the zero waste
philosophy in 2008 aimed at significantly reducing the volume of generated solid waste. For instance,
the County has opened eight new reuse locations where residents may donate household items for
resale, thus reducing tonnage values for disposal or recycling. The County also added a new convenience
center (Ocean View), increased opportunities for scrap metal recycling and yard waste collection at
recycling and transfer stations, and added two new facilities for processing green waste on both the east
and west sides of the island. However, as shown in the Exhibit 2-8, there is a slight uptick in the amount
of materials generated and disposed the last few years, thereby emphasizing the need to continue and
expand zero waste initiatives.

2.3.2 20-Year Projection
To plan for future solid waste management needs, projections are made using a generation forecast
model. The County prepared the 20-year projection by examining forecasted de facto population, past
generation and diversion trends, and potential changes to those trends (Exhibit 2-10). The de facto
generation estimate for 2016 was applied as the baseline for disposal tonnage. The diversion rate
estimate (29 percent = average of approximately 5 pounds/day/per person) is based on the median
diversion rate from FY 2009 through FY 2017. The implementation of additional diversion programs and
other outside factors have the potential to increase or decrease the diversion rate in coming years
beyond the average annual diversion rate. These factors could include:
•Market stagnation. For example, China set new limits on imported recycled materials,
significantly decreasing the amount of recycling accepted.
•Economic trends. An economic upturn typically results in increased waste generation, as well
with a waste generation decrease during an economic downturn. Because Hawaiʻi is a popular
vacation destination, economic trends can be particularly influential.
•County-wide reduction efforts. Ongoing efforts by the County and residents, businesses, and
institutions to reduce waste may help moderate waste generation in the future (i.e., yard waste
mulching facilities introduced during the last planning period).
•Availability of curbside collection infrastructure.
•Availability of educational program funding.
•Improvements to diversion rate calculations. Non-County program recycling – big box stores, for
example.
•Investment in new technology. For example, potential for privately or publicly funded recovery
and treatment facility (e.g., waste to energy [WTE], pyrolysis).
Exhibit 2-10 shows a conservative increased diversion rate of 8 percent through 2039. This is based
on the potential for increased diversion when the proposed compost facility is in operation
(estimated for operation during the early part of the 10-year implementation period, see Chapter 4
for further details). The waste composition study performed in 2008 estimated 16.3 percent of the
waste going into the landfill as food waste (see Section 2.4 Waste Composition). Eight percent
conservatively represents a diversion of half of this total. This 8.0 percent diversion rate is extended
through 2039. Detailed data for Exhibit 2-10 are provided in Appendix C.

2.4 Waste Composition
Hawaiʻi County conducted a waste composition study in 2008, included as Appendix D (CH2M Hill 2008).
That study includes composition estimates for the overall waste stream and results broken down by
recycling and transfer station, commercial, and self-haul wastes 4 disposed at the landfill. The results are
based on samples taken at the WHSL during May 2008. A similar study was performed at the SHSL in
2001 (Cascadia Consulting Group 2001). Results of the 2008 and 2001 waste composition studies and
the 2008 disposal data were combined to estimate the composition of waste that enters both landfills.
The results are combined to provide waste composition estimates for the total County disposal.
Exhibits 2-11, 2-12, and 2-13 show disposed composition estimates for nine waste categories for the
entire County, for West Hawaiʻi, and for East Hawaiʻi, respectively. When combined, organics and paper
comprise more than half of the waste stream. The organics category contains such components as food,
green waste, and textiles. Construction and demolition waste accounts for another 22.0 percent by
weight. The construction and demolition category includes such components as lumber and gypsum scrap.
The composition of waste disposed in West Hawaiʻi is similar to the composition of disposed waste in
East Hawaiʻi. Two differences that merit mention: 1) there are more organics disposed of in West
Hawaiʻi (35.3 percent) than in East Hawaiʻi (29.6 percent); and 2) there is more special waste disposed of
in East Hawaiʻi (5.2 percent) than in West Hawaiʻi (1.9 percent). Most of the special wastes disposed of
in East Hawaiʻi consist of industrial sludge, bulky items, and tires.
The waste stream study includes the amount of waste disposed for 58 different types of waste. County-
wide composition estimates for all 58 waste components evaluated during the study are shown in
Exhibit 2-14.
4 Self-haul refers to waste delivered directly to the landfill (as opposed to a recycling and transfer station).

3.SOURCE REDUCTION
3.1 Introduction
Source reduction adopts practices that generate less waste. Source reduction strategies include changes
in product design and packaging, reduction of consumer purchases, and the reuse of materials or goods.
By decreasing the amount of waste that must be disposed of, waste reduction programs decrease the
environmental issues associated with waste disposal. Reusing a grocery bag, buying materials in bulk,
and reselling or donating unwanted and still usable materials or products are typical examples of
waste reduction.
This chapter describes the County’s source reduction activities, identifies current issues and concerns
regarding current source reduction practices, and presents options for achieving further source reduction.
3.2 Background
3.2.1 Regulatory Context
As described in the Hawaiʻi Revised Statutes Chapter 342G (HRS 342G), each County is required to
consider solid waste management practices and processing methods in the following order of priority:
1.Source reduction.
2.Recycling and bioconversion (including composting).
3.Landfilling and incineration.
HRS 342G-3 established a 25 percent waste reduction goal by 1995, and a 50 percent goal by 2000
through source reduction, recycling, and bioconversion.
Recycling and bioconversion practices were first detailed in the original Integrated Solid Waste
Management Plan created in 1993 and in subsequent updated plans. In 2003, the County passed a
resolution with a goal to divert 50 percent of the solid waste from landfills by 2008 and 80 percent by 2013.
3.2.2 Resolution 356-07 (Zero Waste)
In 2007, the County adopted Resolution 356-07, “A Resolution to Embrace and Adopt the Principles of
Zero Waste as a Long-term Goal for Hawaiʻi County.” The resolution embraces the zero waste
philosophy of solid waste management and commits to taking the necessary steps to incorporate the
zero waste philosophy into legislation, policies, and actions.
The zero waste philosophy is based on the concept that current standards of waste management are
inefficient and unsustainable, and that waste can be virtually eliminated by emulating sustainable
natural cycles, where all discarded materials are treated as resources that can effectively be reused. It is
a whole-system approach that emphasizes a closed-loop production and consumption system by
1.Reducing the volume and toxicity of waste through product and packaging redesign strategies.
2.Reusing materials and products for alternative uses, as well as for their original intended use.
3.Recycling and composting all remaining materials for their best use.
Within the zero waste framework, materials that cannot be easily and conveniently reduced, reused,
recycled, or composted are returned to the manufacturer, who is ultimately responsible for product
2019 Integrated Solid Waste Management Plan Update
County of Hawaiʻi
3-2 August 2020
disposal. The zero waste approach includes aggressive education of public and private entities because
consumer choices are considered to be the driving force in changing consumption and disposal patterns.
With a focus on eliminating waste at the source, one of the fundamental principles of zero waste is
redesigning products and packaging, by considering the entire life cycle of a product. In contrast to the
current emphasis on disposability, products and packaging within the zero waste framework are
designed with an emphasis on minimal use of materials, use of recycled and benign resources, longer
product lives, and maximum potential for every product to be repaired, reused, or recycled. Critical to
this principle is the concept of extended producer responsibility (EPR), a policy tool in which
manufacturers are held legally and financially responsible for the waste and environmental impact
associated with their product and packaging, rather than passing that responsibility on to the consumer.
Under EPR, manufacturers are mandated to “take back” their end-of-life products and create closed
looped systems. As a result, EPR enforces design, production, and packaging strategies that consider the
quantity and type of materials required for production, product lifespan, and the ability with which
products can be disassembled and recycled.
In addition, zero waste emphasizes an aggressive combination of reuse, recycling, and composting.
Within the zero waste framework, all organic materials, including yard trimmings and food scraps, are
composted and treated as “biological nutrients” rather than being disposed of in landfills where they
can potentially contribute to future environmental liabilities. Instead of using revenues generated
through the tax base or other financial resources to build new landfills or incinerators, the zero waste
approach advocates for investment in recycling, composting, and reuse facilities, especially those that
accommodate the entire spectrum of reuse and recycling activities (for example, resource recovery
parks). By supporting the reuse and recycling of discarded products and materials, the zero waste
approach creates jobs and stimulates local economies. According to Eco-Cycle Solutions, recycling
creates an “average of ten times more jobs than trash [landfilling], composting creates at least twice as
many jobs as landfills, and reuse creates as many as 30 times more jobs than landfills” (Eco-Cycle
Solutions 2018). According to the Environmental Protection Agency’s (EPA’s) 2016 Recycling Economic
Information (REI) Report, recycling of construction and demolition waste provides the largest
contribution to job, wage, and tax revenue, followed by ferrous and non-ferrous metals (EPA 2016a).
A Zero Waste Implementation Plan developed for the County in 2008 outlines suggested changes to the
way that solid waste is handled within the County (Recycle Hawaii 2009). As stated in Resolution 356-07,
the County recognizes “that zero waste is a long-term goal and that in the interim, programs may need to
be implemented that may be counter to the zero waste philosophy and are necessary to reach the long-
term goal of zero waste and that such programs should not be prohibited by the embracing and adoption
of the long-term goal of zero waste.” To this end, the components of the Zero Waste Implementation
Plan, which can be realistically achieved during the life span of this Plan, have been incorporated.
In conclusion, the County will continue to take incremental steps toward achieving zero waste in the
long term with the understanding that the ability to truly achieve zero waste is realistically challenging
for an island.
3.2.3 Review of 2009 Plan
Exhibit 3-1 provides a summary of the recommendations put forth in the 2009 Integrated Resources and
Solid Waste Management Plan (2009 Plan) relative to source reduction, and a description of the actions
taken to achieve each recommendation.

Expand reuse facilities. Added Hilo, Kealakehe, Pāhoa, and Wai‘ōhinu reuse centers;
closed Ka`auhuhu (Hāwī) reuse center.
Develop public-private partnerships. The County’s website, HawaiiZeroWaste.org, provides a listing of
private reuse stores. The County contracted Recycle Hawaii to
consult with large-scale Leadership in Energy and Environmental
Design (LEED) construction sites to recommend how
construction and demolition materials could be diverted from
the landfill.
Expand and improve public education and
awareness programs.

and Reuse Center vendors can promote program.
3.3 Existing Conditions
The status of source reduction efforts in the County is described below. This discussion includes a
description of 1) County-operated or sponsored programs, 2) other programs conducted by private
entities, and 3) County staffing levels.

3.3.1 County of Hawaiʻi Waste Reduction Programs
3.3.1.1 Backyard Composting
The County’s Zero Waste website includes links to guidance by the U.S. Environmental Protection
Agency (EPA) and other resources on backyard composting, and locations on the island where
vermiculture bins, worms, and accessories can be purchased.
3.3.1.2 Reuse Centers
Reuse centers are located at eight of the County’s recycling and transfer stations. The County contracts
the management and operation of seven of these facilities, which include Kealakehe, Keauhou, Waimea,
Wai‘ōhinu, Hilo, Pāhoa, and Kea‘au. Laupāhoehoe is a volunteer-based facility. Materials accepted are as
follows:
•Furniture and furnishings.
•Working appliances (contingent on
space availability).
•Office equipment (non-computer or
electronics).
•Toys and baby items.
•Recreational items.
•Small kitchen appliances (e.g., electric
coffee makers, toasters).
•Garden/farm items.
•Tools.
•Books, magazines, music and movie media (CDs, DVDs, Blu-rays, etc.).
•Crafts and craft supplies.
•School supplies.
•Clothing and fabric.
•Home construction and demolition materials (except for Kea’au, contingent on
space availability).
Items are available for free or sold at a modest price, and the revenue is used to partially fund operations
and education outreach programs. Reusable latex paint is collected at Hilo, Kea‘au, and Waimea reuse
centers. The latex paint collected at the select reuse centers and during designated household waste
collection events is sorted and available for purchase at a discount over the retail price of new paint.
Upon written approval from the County’s Contract Manager, the reuse center contractor may be allowed
to collect latex paint at additional reuse centers. No oil-based paint may be collected at any reuse centers
because it requires special handling. The reuse center contractor is also required to provide an area at
the Kea‘au and Hilo reuse centers to collect clean and dry reusable newspaper. The containers are
covered to store the newspaper, which is made into high-quality shredded material that is aesthetically
pleasing (e.g., packing material for island-grown flowers shipped off-island). The Contractor must ensure
that the newspaper is being reused.

2017–18 265.0 175.8 440.8
3.3.1.3 Reduction and Reuse Education
The County has an education program that targets waste reduction and reuse. Its main education
initiatives include:
•Information and resources provided through the County’s HawaiiZeroWaste.org website.
•Newspaper, radio, and television advertising.
•Brochures.
•Community outreach (e.g., promotion of zero waste event planning and reuse centers on
County’s HawaiiZeroWaste.org website).
•Community events.
•Sporting events.
•School programs (e.g., recycling site tours).
•Business education (e.g., HawaiiZeroWaste.org).
More information about these initiatives is provided in Chapter 5 Public Education and Information.
3.3.1.4 Solid Waste Demolition Diversion Plan
The County Department of Environmental Management (DEM) currently works with the County
Department of Public Works (DPW) and County Planning Department to advise developers with large
projects with alternative ways to dispose of demolition waste other than the landfill. The County DEM
also routinely comments on National Environmental Policy Act (NEPA) environmental assessments (EAs)
and environmental impact statements (EISs) for development projects, advising the project proponents
to consult with the DEM to determine the best way to dispose of demolition waste. The DEM’s
comments on NEPA environmental documentation often result in projects that are committed to
alternative methods of handling demolition waste in lieu of landfilling.
2019 Integrated Solid Waste Management Plan Update
County of Hawaiʻi
3-6 August 2020
Common materials recycled through this program include roofing, steel posts, and gutters. Concrete
rubble from foundations or other structures is usually reused as fill material and road subgrade once the
rebar is removed. Asphalt, otherwise called “reclaimed asphalt pavement” is reused in asphalt
pavement mixtures, road base course, or utility backfill.
3.3.1.5 Procurement Policies
Public sector procurement can help reduce waste, foster reuse of products, and stimulate markets for
recyclable materials and compost. In addition, these procurement policies can serve as a model for
other entities, including private sector businesses and institutions.
Pursuant to HRS 342G-41-44, the County has a policy to “give preference to vendors who utilize
products with recycled content,” when purchasing paper and plastic materials (for example, office
paper, printed materials, plastic bags, and so forth), and has a policy to make double-sided copying
standard practice at County offices.
3.3.1.6 E-Waste Producer “Take-Back” Program
As of 2010, the State of Hawaiʻi legislature enacted Act 13 to encourage recycling of electronics, and
mandated manufacturers to establish, conduct and manage take-back recycling programs for “covered
electronic devices” (CEDs). Act 13 was revised in 2011 to include “covered televisions” (CTVs) [herein
referenced as e-waste]. The HDOH is responsible for implementing the program. County public
awareness campaigns educate residents on e-waste programs and promote collection events. The
County contracts for the collection of e-waste products, which are then shipped off island for proper
disposal or treatment. See Chapter 6 Household Hazardous Waste and Electronic Waste for more
information related to the e-waste take-back program.
As described in Section 3.3.1.2, seven reuse centers throughout the County allow residents to drop off
unwanted and still useful non-e-waste electronics such as small kitchen appliances for purchase at a
nominal fee.
3.3.1.7 Product Bans
Since the 2009 Plan, the County regulates the use of plastic bags and polystyrene foam food containers
to reduce landfilling of these products and for gaining the overall environmental benefits. Hawaiʻi
Ordinance 121, as codified in Chapter 14 of the Hawaiʻi County Code (HCC), bans businesses from
providing plastic checkout bags to their customers and encourages use of environmentally preferable
alternatives, such as reusable bags. This law went into effect in 2013.
Pursuant to HCC 20-60, the County proposes to reduce the use of polystyrene foam food containers and
food service ware by restaurants, supermarkets and other vendors, eliminate the use of polystyrene
foam for packaging prepared and unprepared food, and in doing so promote the use of environmentally
preferable alternatives. Under this reduction plan, outside purveyors are encouraged, and not required
to use alternative packaging to polystyrene foam. On July 1, 2019, all food vendors and County facility
users (i.e., concession contracts with the County, renters of County facilities) using disposal food service
ware are required to use recyclable or compostable products. If not exempted and found out of
compliance, a fine may be imposed by the County; the amount ranges from $10 to $600 depending on
the circumstances. In preparation for the ban, the County established an education program for
businesses, nonprofits, and the public regarding compostable alternatives to polystyrene foam.
2019 Integrated Solid Waste Management Plan Update
County of Hawaiʻi
August 2020 3-7
3.3.1.8 Private Reuse Programs
In addition to the County reuse centers, there are several for-profit and nonprofit reuse facilities. For
example, Habitat for Humanity Restores, located in Kona and Waimea in West Hawaiʻi and in Hilo in East
Hawaiʻi, emphasizes reusable building materials, as well as products returned to local “big box” stores,
such as Wal-Mart. Home building items accepted by Habitat for Humanity include lumber (greater than
4 feet long), kitchen and bathroom fixtures, doors, windows, concrete blocks and bricks, latex paint,
large appliances, and light and fan fixtures.
Re-use Hawaiʻi, a local nonprofit deconstruction company, salvages building materials for reuse on other
construction projects. Re-use Hawai’i opened their West Hawai’i location in 2018 in Kona. Their first job
involved dismantling the Kona Village Resort, which was destroyed by a tsunami in 2011. Re-use Hawaiʻi
sells lumber and other building materials at their redistribution center at a discounted price if the
materials have undergone a two-step quality control. The cost of the operation requires approximately
10 percent of its annual budget from outside sources with donations from local foundations and grants
from the State. These funds supported the company’s expansion from O`ahu to West Hawaiʻi (West
Hawaiʻi Today 2019).
There are also a variety of other reuse businesses throughout the island – thrift shops and consignment
stores, appliance stores, swap meets, and used book stores that sell used merchandise, such as
furniture, rebuilt appliances, clothing, housewares, and books. Many local businesses also accept
packing materials such as bubble wrap and foam peanuts.
The DEM website, HawaiiZeroWaste.org, provides a listing of for-profit and nonprofit reuse centers
throughout the island with store locations, contact phone numbers, and hyperlinks to reuse websites.
3.3.2 County of Hawaiʻi Staffing Levels
Successful delivery of local government waste reduction programs requires devoting an appropriate
amount of resources including staffing. The County has demonstrated its commitment to waste
reduction by assigning the following staff to County waste reduction and recycling programs:
•One full-time recycling coordinator.
•Two full-time equivalent (FTE) recycling specialists for the HI-5 recycling program.
•Three FTE recycling specialists.
The County recycling staff conducts most education and outreach activities. The County has a contract
with a consultant to help develop and enhance the education and outreach programs, as described in
greater detail in Chapter 5 Public Education and Information.
3.4 Issues and Concerns
As described above, several source reduction activities are conducted in the County, including programs
and initiatives by the County as well as other organizations. There is more that could be done by the
County and waste generators to promote changed behaviors that would ultimately reduce the quantity
of materials entering the waste stream. The need to implement additional programs and policies is
further established by the County’s commitment to greater diversion.
3.5 Options for Improvement
Pursuant to HRS 342G-26, an overview of various measures that could be implemented to increase
source reduction is provided below. These options were developed based on successful initiatives
2019 Integrated Solid Waste Management Plan Update
County of Hawaiʻi
3-8 August 2020
implemented in other jurisdictions that may be applicable and appropriate for the County. Note that the
options focus on waste reduction and reuse; education, recycling, and composting programs are
discussed in other chapters of this Plan update.
3.5.1 County Source Reduction Practices
The County has an opportunity to serve as a model for the entire island and demonstrate their
commitment to waste diversion by implementing comprehensive source reduction policies for all
County operations. The County could make a more pronounced commitment to environmentally
preferable products. This effort could include an evaluation of current practices at all County offices and
buildings, and identification of opportunities for increased source reduction. All County employees could
be provided with documents providing information about the County’s commitment to zero waste, and
ideas of how each employee and department can reduce their waste.
Specific policies and activities that the County could adopt include the following:
•Implement an environmentally preferable purchasing policy and additional environmentally
preferable procurement guidelines. Set environmentally preferable purchasing and recycled
content as “defaults” for departments to use in departmental purchases of supplies and
equipment not centrally procured.
•Establish a Zero Waste Purchasing Committee with a mandate to develop the County’s
purchasing policy.
•Include measurable zero waste goals in job descriptions and annual performance evaluations.
•Establish a Green Building Policy and evaluate the extent to which those policies can be
encouraged or required for new private construction and major renovation projects.
•Use electronic mail, document storage, and retrieval systems to achieve a “paperless office.”
•Accept electronic submittal of all applications and required submittals.
•Provide incentives for staff members who develop and implement new initiatives that
reduce waste.
•Promote and encourage in-house composting programs.
•Encourage or mandate the use of reusable mugs, plates, and silverware and install dishwashers
in County facilities where feasible.
•Publish major accomplishments and progress of each department on the County website.
The federal government has undertaken various initiatives to include the environment in its purchasing
decisions. The County could consider EPA’s Comprehensive Procurement Guideline program as a model
for helping its employees purchase products that use materials recovered through recycling (EPA 2016b).
Cost Considerations. Many County actions could be accomplished at little or no cost. The initial review of
purchasing policies would require staff resources throughout many departments, but it is unlikely that
additional staff would be required. Green building policies will increase the cost of construction
somewhat; estimates on the extent of likely increases differ, and many jurisdictions have successfully
implemented such policies. Purchasing policies can increase the cost of materials; however, the higher
costs could be offset by efforts to eliminate certain products from the waste stream (plastic flatware) or
by reduction efforts (paperless office). The net result would probably be a small percentage increase in
costs for many County activities and material purchases.

County of Hawaiʻi
August 2020 3-9
3.5.2 Business Waste Audits and Reduction Plans
The County currently provides a dedicated page to businesses on their HawaiiZeroWaste.org website.
Information on the dedicated business page includes guidance for the handling of hazardous materials
and promotion of a business waste reduction plan for environmental benefits as well as savings in
disposal costs. The web page also includes links to information from other websites including: the City
and County of Honolulu Department of Environmental Services “How to Conduct a Waste Audit” guide,
Hawaiʻi Green Business Program at the Hawaiʻi State Energy Office (greenbusiness.hawaii.gov), the EPA
(e.g., WasteWise Program, Procurement Guidelines), and Energy Star. The County would expand their
business waste reduction program by teaming up with others (e.g., grassroots organizations such as
Zero Waste Big Island and Recycle Hawaii) to conduct business waste audits, provide outreach, or
develop an updated business recycling and reuse guide (the latest version is reported to have been
produced by Recycle Hawaii in 2005).
As part of the County’s effort to work with local businesses to reduce waste, the County could conduct
outreach to local businesses to:
•Encourage retailers and their suppliers to take back products and packaging that are currently
difficult to reuse, recycle, or compost. Potential take-back programs could be publicized by
posting all cooperating retailers on the County’s website and publishing frequent articles and/or
advertisements in the local newspaper and County newsletter.
•Teach environmentally sensitive lean manufacturing practices to reduce or eliminate non-
reusable packaging, transport containers, and serviceware. This effort could target both
organizational processes and retail practices.
•Advertise on the County’s HawaiiZeroWaste.org website opportunities for material exchanges to
foster business-to-business connections to match unwanted material byproducts or
commodities for reuse or recycling as feedstock.
Cost Considerations. The cost of this option would differ depending on the speed of implementation.
County staffing levels would need to increase to implement and manage the program.
3.5.3 Construction and Demolition Diversion
As described in Section 3.3.1.4, the County DEM currently works with the DPW and County Planning
Department to assist developers with large projects in finding alternative ways of disposing demolition
waste other than the landfill, and similarly advises large development proponents through the NEPA
process. The County would expand the program to emphasize building deconstruction and support
local initiatives for adaptive reuse of materials generated during deconstruction projects. Initiatives
could include:
•Require demolition projects to publicize in the local newspaper to solicit salvage of reusable
items by deconstruction companies.
•Include a dedicated page on the HawaiiZeroWaste.org website that emphasizes construction
and demolition recycling and reuse. It could include “how-to” guidance on deconstruction and a
listing of available deconstruction companies on the island.
•Require contractors to separate reusable or recyclable construction and demolition debris from
non-recyclable materials as a component of permit conditions.
•Separate ceramic items, such as sinks and toilets from the waste stream, and utilize the crushed
material in construction.
•Construct a construction and demolition demonstration salvage yard in East Hawaiʻi.

Cost Considerations. The cost of this option would differ depending on the speed of implementation. At
least initially, there would be some added cost to businesses to conduct audits and change existing
material management methods. County staffing levels would need to increase to implement and
manage the program.
Chapter 9, Sections 9.7 and 9.8, discuss the option and recommendation to develop a Construction and
Demolition landfill with a sorting and reuse area.
3.5.4 Visitor Industry
Because tourism is one of the largest industries in the County, hotels, motels, and other lodging facilities
contribute a significant portion of the County’s waste. There are a variety of basic measures that these
facilities can implement to reduce their waste stream, including:
•Replace disposable products with reusable products (utensils, dishes, cleaning supplies).
•Buy in bulk, when possible.
•Offer newspapers only upon request.
•Change linens only upon request.
•Utilize soap and shampoo dispensers rather than disposable containers.
•Utilize air hand dryers or reusable napkins in public restrooms, rather than disposable.
•Change lighting fixtures to LED (light emitting diode) bulbs.
•Practice grasscycling.
•Implement onsite composting.
•Donate or sell lightly used furniture or appliances instead of landfilling.
This program could be implemented as a sub-element of a broader business waste audit and reduction
program (see Section 3.5.2), or as a stand-alone program. The County could seek partner businesses and
organizations within the visitor industry to build on existing waste reduction efforts by industry. At least
initially, there would be some added cost to businesses to change existing material management methods.
Cost Considerations. The cost of this option would differ depending on the speed of implementation.
County staffing levels would need to increase to implement and manage the program.
3.5.5 Reuse Facilities
As described in Section 3.3 Existing Conditions, the County currently contracts seven reuse centers, and
one reuse facility is managed by volunteers, which is far greater than the number of facilities in
operation at the time of the 2009 Plan. All reuse centers have been successful at diverting household
products and, to a lesser extent, construction (demolition and deconstruction) materials from the
landfills. The County has three options:
•Expand and develop more reuse centers.
•Improve programs at existing facilities.
•Increase promotion of the many for-profit and nonprofit thrift stores throughout the County.
The Reuse Center at Laupāhoehoe is run by volunteers with assistance from the solid waste facility
attendants from time to time to remove large items. The County has considered upgrading the
volunteer facility at Laupāhoehoe and contracting the management; however, the amount of overall
waste diverted from the landfill is relatively low and resources are better used elsewhere. Instead of
2019 Integrated Solid Waste Management Plan Update
County of Hawaiʻi
August 2020 3-11
investing in new facilities, the County is working with the contractor responsible for managing the
existing facilities to improve operations as follows:
•Develop and communicate to residents a list of the highest priority materials to maximize the
type and quantity of materials that can be accepted.
•Be selective about merchandise, emphasizing items that are lightly used, clean, and in good
condition.
•Improve signage.
•Provide more covered space.
•Improve organization and display of merchandise.
The County could also work collaboratively with the volunteer-based Laupāhoehoe site to increase
participation, which has decreased since the initial enthusiasm around the program. If the acceptance of
highest priority materials results in greater diversion, expanding the program to other recycling and
transfer stations, or upgrading the Laupāhoehoe Reuse Center could be considered.
The County could increase their support of other thrift stores (for-profit and nonprofit) by providing an
interactive map showing store locations and providing details on materials accepted on the
HawaiiZeroWaste.org website or through other promotional efforts such as radio or other media. This
support could focus on stores that divert construction demolition and deconstruction materials because
this is a significant portion of the waste stream (estimated at 22.2 percent in 2008).
Cost Considerations. The cost of expanding facilities would depend on the number of facilities
constructed, site-specific design considerations, and the resources devoted to staffing and outreach at
each facility. The cost of improving the functionality of existing facilities to increase waste diversion
would be nominal.
3.5.6 Establish Pay-As-You-Throw System for Residential Discards
Implementing a pay-as-you-throw (PAYT) system creates a financial incentive for residents and businesses
to reduce their waste. As reported in the most recent EPA co-sponsored publication, PAYT systems, also
known as variable rates programs or user pay, ask households to pay more if they put out more garbage
for collection. According to the EPA, the most effective way for local governments to reduce residential
solid waste, increase recycling, and decrease waste-related greenhouse gas emissions is by implementing
PAYT programs (EPA 2016c). A 2017 study of 20 municipalities in the State of Maine concluded that
communities with PAYT generated, on a per capita basis, 44.8 percent less trash than those without PAYT.
In this same study it was estimated that communities with PAYT generated approximately 340 pounds of
residential trash per capita of municipal solid waste (MSW) per year compared to non-PAYT communities
that generated approximately 645 pounds (WasteZero 2015a). PAYT provides a powerful financial
incentive for residents to reduce waste discards.
A good example of a smaller jurisdiction in the State of Hawaiʻi implementing a PAYT program is the County
of Kaua’i. In 2014, the Kaua’i County Council passed PAYT Ordinance 975. The ordinance went into effect in
July 2015. An important component of the program was the development of an implementation plan that
was funded through the EPA Region 9 Solid Waste Management Assistance Grant (County of Kaua’i 2018a).
In the County, this program could be implemented in multiple ways:
•PAYT at County Recycling and Transfer Stations: Charge residents on a volume or weight basis
for garbage delivered to County recycling and transfer stations while allowing drop-off of
recyclable or compostable materials at no charge.
2019 Integrated Solid Waste Management Plan Update
County of Hawaiʻi
3-12 August 2020
•Provide Universal Collection with PAYT Rates:
Implement universal collection for households in densely populated areas and charge rural
residents on a volume or weight basis for garbage delivered to County recycling and transfer
stations, while allowing drop-off of recyclable or compostable materials at no charge.
Implement universal collection for households in densely populated areas and charge a base
fee to all residents (including those who opt out of universal collection or rural populations
that are outside the universal collection zones), while allowing drop-off of recyclable or
compostable materials at recycling and transfer stations at no charge.
Implement universal collection of garbage for all households in the County.
Except for the universal collection program that would charge a base fee to all residents, the above
options have the additional benefit of eliminating misuse of the recycling and transfer stations by non-
residential generators. To successfully implement a PAYT program, it is advisable to develop a study or
implementation plan to fully understand the system that would work best for the residents of the
County. A discussion of each option follows.
3.5.6.1 PAYT at County Recycling and Transfer Stations
PAYT could be implemented at County recycling and transfer stations by establishing rates either
proportionally by volume or by weight, which would be charged for discarding materials at each station.
Another option could be a flat rate.
Option 1: Bag or Tag Proportional Pricing System
Typical volume rates include some combination of per-bag and per-vehicle fees. Because the County
would prefer to avoid security and other issues relating to collection of fees at recycling and transfer
stations, this system could be implemented using pre-purchased bags or tags, eliminating the need to
collect fees at the recycling and transfer stations. Residents would be provided a pre-determined
number of County-approved garbage bags, or tags that can be used for disposing of larger items.
Additional bags or tags could be purchased from the County or through local retail outlets.
To implement this option, all recycling and transfer stations would need to have a full-time attendant to
monitor residential disposal. In addition, the program would need the following:
•Adequate bins for dropping off readily recyclable materials at, or nearby, the recycling and
transfer stations.
•A small building or other structure for an attendant to use while monitoring incoming loads.
•Adequate space to allow for vehicle queuing at the recycling and transfer stations.
•An agreement with retail stores to sell pre-approved bags or tags on behalf of the County.
Option 2: Variable Rate Three-Can System
The County could consider charging residents based on the volume of cans (e.g., 12- [“micro can”], 20-,
32-, 64-, or 96-gallon) they dispose of at their local recycling and transfer station. In this option,
residents may haul their rubbish, green waste, and recyclables to their nearest recycling and transfer
station. The onsite attendant would visually count the number, size, and type of cans. Variable rates
would be enforced for the type of waste (green waste, rubbish, or recyclables) as well as the number
and size of the cans.
2019 Integrated Solid Waste Management Plan Update
County of Hawaiʻi
August 2020 3-13
This option would require:
•Adequate space to allow for vehicle queuing at the recycling and transfer stations.
•A small building or other structure for an attendant to use while monitoring incoming loads.
•Collection of fees at the recycling and transfer stations.
Option 3: Variable Rate Scale System
The County could consider a PAYT system that is established by weight through the installation of scales
at the County recycling and transfer stations. An inbound and outbound scale would have to be installed
at the station. Because of the high initial costs of this option, scales could be installed at recycling and
transfer stations that experience the highest traffic and disposal volumes. Residents would drive onto an
inbound truck-mounted scale, dispose of their waste, drive onto an outbound scale, and pay the
attendant for the per pound weight difference.
This option would require:
•Installation of an inbound and outbound scale.
•Installation of a recording system.
•Adequate space to allow for vehicle queuing at the recycling and transfer stations.
•Collection of fees at the recycling and transfer stations.
Option 4: Multi-tiered Pricing
According to the EPA, multi-tiered pricing generates the greatest revenue for localities (EPA 2016c).
Through this system, residents are required to pay a monthly fee for baseline solid waste service. The
County may require residents to pay for every bag and/or cart they fill on top of this fee, or they may
include up to two or three bags/cans per week into the baseline fee (Solid Waste Association of North
America [SWANA] 2007). If residents exceed this amount, they will be required to pay a second tier for
additional bags or containers they fill on top of this fee. Residents must then pay a second tier to
dispose of extra waste, which may be based on volume (SWANA 2007). Recyclables and green waste
could then be collected at a reduced fee or for no charge.
Option 5: Automated Transfer Station Pay Station
The County could install self-service
electronic fee payment mechanisms at all
recycling and transfer stations that charge a
flat fee. The County could also consider
installing a self-operating compactor as a
component of the system, which would
charge customers based on weight.
For example, a gated customer-operated
drop box is in operation in rural Skykomish,
King County, WA, allows customers to drive
up to an automated gate, make payment at a
self-service kiosk, and then enter the gated
area to dispose of their solid waste into two
top-loading drop boxes, each with two stalls. It does not have a self-operating compactor. Recycling
facilities are also provided outside the gated area, allowing customers to drop off recyclables without
paying a fee. The waste ultimately ends up being transported to a transfer station 50 miles away for
Automated Rural Drop Box Pay Station in Skykomish, WA Source:
King County (2018)
2019 Integrated Solid Waste Management Plan Update
County of Hawaiʻi

eventual disposal at the regional landfill. Because of its remote location, cameras are used to monitor
activities, and staff make regular visits for maintenance. King County’s Solid Waste Division has formed a
partnership with the Road Services Division in which staff working at the adjacent road services facility
regularly monitor the site.
Some of the challenges related to the Skykomish self-operating system includes illegal dumping
(including in the recycling bins), little to no control of materials that require special handling (e.g.,
hazardous waste), exceedances of load limits, unwanted visitors (e.g., black bear, people scavenging
during afterhours), loss of revenue, and maintenance of bins for proper weight distribution. However,
the advantages of the Skykomish rural drop box includes rubbish collection for an underserved
community, the availability of recycling, opportunities to educate customers, and the partnership with
the Road Services Division.
In the County, potential complications of such a system could include:
•Upfront cost of fee payment technology and compactors at recycling and transfer stations
lacking these facilities.
•Upgrades to existing compacting systems for use by the public.
•Maintenance of fee-payment systems and security cameras.
•Administrative costs (although this would be realized in varying degrees with any PAYT
program).
•Potential safety issues (people operating compactors).
•Potential for illegal dumping.
•If unstaffed, issues with weight distribution in drop box.
However, the introduction of such a system would have the advantage of less reliance on the general
fund, and the potential reduction in recycling and transfer station staffing.
Conclusion
It is possible that not all recycling and transfer stations would have the physical space to accommodate
the infrastructure needs for a PAYT system – some stations may need to be closed, relocated, or
substantially modified to implement this program. There is the potential to consolidate “wastesheds” to
fewer facilities (i.e., closing some and enhancing others based on usage and/or distances from
population centers to the facilities). Chapter 8, Section 8.7.6, identifies potential recycling and transfer
stations for optional closure.
Implementation of these options would require an aggressive public education and information
campaign to ensure that residents understand the rationale for implementing the PAYT program.
Cost Considerations. Estimating the initial infrastructure costs for this option would require conceptual
designs at each of the County’s 22 recycling and transfer stations. The infrastructure cost could vary
considerably depending on site-specific conditions and the extent to which modifications are feasible
at each station. The County would need to modify its financial systems to account for the new
revenue source.
3.5.6.2 Universal Collection with PAYT Rates
While not unprecedented, the County’s current system of solely providing recycling and transfer stations
distributed throughout the County is a relatively uncommon way of providing garbage collection
services to residents. PAYT rates could be implemented to provide universal garbage, recycling, and
2019 Integrated Solid Waste Management Plan Update
County of Hawaiʻi
August 2020 3-15
perhaps organics collection services to all County residents. Elsewhere in the United States, residential
collection services typically are either provided by local government or by the private sector under a
contract or franchise arrangement. The Supreme Court of the State of Hawaiʻi “Konno decision”
affirmed the rights of the United Public Workers (UPW) union to perform work that “customarily and
historically” had been performed by government workers. However, subsequent to that ruling, the
Hawaiʻi Legislature in HRS 46-36 provided for a “managed competition” process in which local
government and the private sector would compete on the basis of efficiency, effectiveness, and price for
new government services. Additional research would be needed to decide the best way to proceed with
universal collection if this is an option the County would like to implement.
PAYT collection rates can take many forms including using a variable can, metered bag, or metered tag
system. The key aspect of this system is to charge a progressive rate for each additional garbage unit
collected above the basic service level (e.g., one can per week).
Like PAYT at County recycling and transfer stations, implementation of this option would require an
aggressive public education and information campaign to ensure residents understand the rationale for
implementing the PAYT program.
Significant upfront planning would be required. The County would need to establish billing systems and
a customer service organization, and modify its financial systems to accommodate this new service.
The County could elect to assess the potential for reducing property taxes as an offset to the new
revenue source.
Cost Considerations. The County of Kaua`i PAYT variable rates are $10 per month for a 64-gallon cart
and $18 per month for a 96-gallon cart. Service is once per week. Everyone pays a $6 base fee whether
they have County-provided collection service or opt out and only use the County-operated recycling and
transfer stations. They provide a 50 percent cost reduction for low-income households, both on the base
fee and the rubbish collection fee.
3.5.7 Expanded Home Composting Program
Since the 2009 Plan, the County has decreased emphasis on a public campaign
around home composting, which formerly entailed educational workshops and
distribution of backyard composting units. The County’s home composting
promotion is now primarily emphasized on the HawaiiZeroWaste.org website,
which includes links to EPA guidance and other resources on backyard
composting, and locations on the island where worm bins, worms, and
accessories can be purchased. The program could rekindle a more aggressive
promotion campaign and a target penetration rate of at least 25 percent of
single-family households within 5 years.
Cost Considerations. The County would have to consider the cost for purchase,
storage, and delivery of each unit. Existing staff resources would need to be used to develop the plan for
how best to distribute the units and to provide suitable promotion and user education.
3.5.8 Expanded Reusable Bag Program
As part of their educational outreach program, the County has conducted Bring-Your-Own Bag (BYOB)
promotional events at local grocery stores and at various community events such as Earth Day, during
which reusable grocery bags are given to interested residents. To expand this program, the County
could significantly increase the number of reusable bags that are distributed to residents, and expand
2019 Integrated Solid Waste Management Plan Update
County of Hawaiʻi
3-16 August 2020
its outreach to encourage participating grocery stores to increase the financial discount for using
reusable bags.
Cost Considerations. This option would require additional staff time and funding for additional
materials.
3.5.9 Expand Source Reduction Education
A key to successful reuse programs is the education of the staff (government, private for-profit, and
nonprofit) who operate the facilities within the program. Once staff have been trained on program
basics, they will need to develop systems to implement programs for the public. The methods for
providing materials to markets include retail sales, dismantling for recycling, and ensuring materials
reach markets accessible to the public.
Chapter 5 Public Education and Information includes a series of proposed enhancements to the County’s
education and promotion programs.
3.5.10 Establish Extended Producer Responsibility Policy
As previously described, EPR is a policy tool that extends manufacturer’s responsibilities to include
responsibility for life cycle costs of their products and associated packaging. This approach has been
successfully implemented in various communities throughout Europe and Canada, as well as parts of the
United States.
When considering the life cycle of a product, manufacturers should take into consideration the
environmental footprint of a product, from its beginning to end of life. Through EPR, the responsibilities
and life cycle costs of their products and packaging shift from municipalities towards manufacturers. For
instance, through EPR, producers analyze the natural resource, energy, packaging, and transportation-
associated costs and impacts of their products (MacKerron 2012).
In 2012, 32 states enacted greater than 70 producer responsibility laws, including products such as
batteries, telephones, paint, pesticide containers, carpet, and fluorescent lamps. However, none of
these programs took into consideration product packaging (MacKerron 2012). Around the globe, British
Columbia mandated a fully funded EPR paper and plastic packaging program by manufacturers in 2014
(Resource Recycling Inc. 2016); after 1 year, the province reported a 77 percent recovery rate. In
Europe, since the European Union’s adoption of EPR in 1994, 25 member states have enacted national
packaging policies and achieved a 65 percent recycling rate in 2012 (EUROPEN 2018).
Some policy statements the County may want to consider include the following:
•Express support for state and federal policies to eliminate subsidies, internalize externalities for
virgin material production and wasting, and involve producers in taking physical and/or financial
responsibility for their products and packaging through reuse, repair, or recycling.
•Express support for state and County agencies to support product stewardship, by creating a
state/counties coalition to work towards EPR, along with other active states.
•Express support for policies designed to relieve local taxpayers from the burden of managing
wastes they have no control over. This could include identifying specific product categories that
have the greatest impact on local programs.
•Express support for mandatory recycled content, as well as “cradle-to-cradle” product take-back
and recycling services. Insist that the cost of the programs be paid by manufacturers and
internalized into the cost of their products.
2019 Integrated Solid Waste Management Plan Update
County of Hawaiʻi
August 2020 3-17
EPR framework policy and legislation can be drawn from successful programs implemented in California,
Oregon, Washington, and Minnesota, as well as other areas of the world including Belgium, the
Netherlands, and Germany.
Cost Considerations. To implement this option, the County would need to invest some ongoing staff
time and potential consulting assistance for research, policy analysis, and drafting legislation. The price
of some products affected by EPR programs could increase depending on implementation.
3.5.11 Create a Zero Waste Fund
To encourage local innovation and participation, the County would fund community zero waste
initiatives with fees levied on landfill disposal. The County could leverage private sector investments by
adopting supportive policies and by providing technical assistance, matching funds, and letters of
support for independent financing and/or grants. The more that nonprofits and private companies
invest in expansion of reuse, recycling, and composting programs, the less the County needs to invest.
The County could also identify and support proposals for state, federal, and foundation grants and loans
for local zero waste businesses and service providers.
For example, in Boulder, Colorado, the Boulder County Resource Conservation Division distributes
$50,000 annually as part of its Zero Waste Funding Program. Since 1997, they have awarded over one
million dollars for education and infrastructure initiatives to businesses, residents, and governments.
Cost Considerations. The cost of this option would depend on the extent to which the County elects to
fund this program. Some added staff time would be necessary to develop and administer the program.
3.5.12 Public-Private Partnerships with Community-Based Organizations
A survey of the reuse industry (e.g., Goodwill Industries, Habitat for Humanity) on the island would be
beneficial. Other nonprofits or businesses may be interested in participating in reuse programs within
the County. The County could convene a meeting of interested parties to determine the level of interest,
evaluate what challenges such a program would face, and identify potential mechanisms to assist with
initiation of the program.
Independent community-based organizations (CBOs) may see this as an opportunity. They are
potentially available to take on repairing and refurbishing as well as dismantling of discarded items into
recyclable commodities.
Cost Considerations. Some added staff time would be necessary to develop and administer the program.
3.6 Recommendations
Based on the analysis presented above, and discussions with the SWAC, the Plan recommends the
following to improve the source reduction program:
1.Develop County policies or ordinances that mandate certain actions be taken to reduce the source
of waste currently entering landfills, including:
Develop a County ordinance that requires a waste reduction plan be submitted to obtain a
commercial building permit. Coordinate implementation with the County Planning
Department.
Work with other counties to develop EPR policy statements or resolutions expressing strong
support for initiatives that require manufacturers of certain products or materials to take
responsibility for the life cycle costs of their products. As a component of the EPR policy,
2019 Integrated Solid Waste Management Plan Update
County of Hawaiʻi
3-18 August 2020
implement a campaign to develop EPR for difficult-to-recycle products, and lobby state and
federal lawmakers to advance EPR initiatives.
Implement a County government source reduction program by implementing policies,
procedures, and incentive programs that will reduce waste streams currently being
generated within various County departments and agencies.
2.Investigate a PAYT program or other funding method. A critical element of the County waste
management program is to provide incentives for the public to participate in source reduction and
other programs to reduce waste going to landfills. PAYT programs have proven to be a highly
successful and cost-effective method of reducing waste going to landfills in many similar
communities nationwide. After considerable deliberation by the SWAC about its advantages and
disadvantages, this Plan update recommends conducting a feasibility study regarding the
implementation of a PAYT program or other funding method. The feasibility study of a PAYT
program or other funding method would include the following components:
Suite of funding mechanisms and logistics for implementing programs (i.e., capital
improvements, administration, self-haul versus collection, or a combination of the two).
Education and public outreach campaign (including retail businesses) that would be
necessary for the implementation.
Pilot program that would be at no cost to the public to introduce the program and identify
ways in which the program can be implemented most effectively.
Training for County staff to implement the program.
“Phasing-in” of the program, which would span over several years.
Prevention of illegal dumping.
Plan for monitoring and evaluation of program results and participation.
Note: Chapter 8, Section 8.8 (Recommendation 1) discusses the continued operation and
maintenance of recycling and transfer stations until a decision on the best method of
collection and transfer is determined, and to also explore alternative funding mechanisms
via a feasibility study. Chapter 10, Section 10.6 (Recommendation 1) discusses a Solid Waste
System Financial Analysis.
3.Improve the current reuse facility program. One of the most popular existing waste reduction
programs among County stakeholders is the operation of reuse facilities where unwanted products
that are still useful can be made available to others rather than discarded. Several recommendations
relating to improving the current reuse program include the following:
Work with contractors managing reuse centers to create a list of preferable donations to
distribute to customers.
Work with the contractor managing the reuse centers to be more selective about
merchandise, emphasizing items that are lightly used, clean, and in good condition. Improve
signage, organization, and display of merchandise.
Provide more covered space at reuse centers.
Collaborate with the volunteer-based Laupāhoehoe Reuse Center to increase participation
of volunteers.
Continue public-private partnerships with organizations such as Goodwill Industries to
develop reuse centers at existing outlets within the County.
Consider expanding the program to other recycling and transfer stations and/or upgrade the
Laupāhoehoe Reuse Center.

County of Hawaiʻi
August 2020 3-19
If improvements to the existing reuse facility program results in greater diversion, expanding the
program to other recycling and transfer stations or upgrading the Laupāhoehoe Reuse Center
could be considered.
4.Expand and improve public education and awareness programs. Stakeholders agreed that
education was a key element of implementing source reduction programs within the County. The
following are recommendations regarding development of educational programs:
Develop a business waste audit and education program to foster source reduction within
the local business community.
Develop a visitor industry waste reduction education program.
Continue reuse education, outreach, and public awareness campaign to encourage public
participation and use of the reuse centers.

4.RECYCLING, BIOCONVERSION, AND MARKETS
4.1 Introduction
Recycling and bioconversion involve reprocessing materials that would have been disposed as solid
waste into new and marketable products. Common recycled materials include beverage containers,
paper products, and scrap metal. Bioconversion consists of processing organic materials such as grass,
leaves, branches, untreated wood, or food to produce new products, such as compost and fertilizer,
using biological means.
This chapter describes existing recycling and bioconversion activities within the County, identifies issues
and concerns with respect to current recycling and bioconversion practices, and presents options for
achieving the County’s recycling and bioconversion goals.
4.2 Background
As discussed in Chapter 3, the State of
Hawaiʻi prioritizes solid waste
management practices and processing
methods for each county according to
Hawaiʻi Revised Statutes Chapter
342G-2 (HRS 342G-2). This chapter
covers the State’s second priority –
recycling and bioconversion (including
composting). Furthermore,
HRS 342G-3 established a 25 percent
waste diversion goal by 1995, and a
50 percent goal by 2000 through
source reduction, recycling, and
bioconversion.
Recycling and bioconversion practices
were first detailed in the original Integrated Solid Waste Management plan created for the County in
1993 and in subsequent updated plans. In 2003, the County passed a resolution with a goal to divert 50
percent of the solid waste from landfills by 2008 and 80 percent by 2013.
4.2.1 Zero Waste
In 2007, the County further enhanced solid waste practices and concepts by adopting Resolution 356-07, a
zero waste philosophy toward solid waste management. In 2008, the County passed Resolution 766-08
urging the state to enact legislation to shift costs and responsibilities for waste management from local
governments to manufacturers of products and create incentives for product redesign. In 2008, the
County contracted with Recycle Hawaii to conduct a zero waste implementation plan (Recycle Hawaii
2009). The Zero Waste Implementation Plan was completed in March 2009. The Zero Waste
Implementation Plan evaluates resource management options including reuse, recycling, composting, and
special discards management, among others, that may help the County achieve its waste reduction goals.
The Zero Waste Implementation Plan includes input from 12 stakeholder meetings and a Zero Waste
Conference. These were held in September 2008 at multiple locations in the County to present zero

waste concepts, and receive input from local residents and business owners about ways to turn
currently discarded materials into resources. The plan received input from over 300 participants.
The recommendations of the Zero Waste Implementation Plan have been incorporated into this Plan
update, where applicable, based on consensus of the SWAC, and Solid Waste Division (SWD) staff.
Greater detail regarding the Zero Waste philosophy and the implementation plan is provided in
Chapter 3, Section 3.2.2.
4.2.2 Review of 2009 Plan
Exhibit 4-1 provides a summary of the recommendations from the 2009 Plan relative to recycling,
bioconversion, and marketing, and describes the actions taken to achieve each recommendation.
Exhibit 4-1. Status Update of 2009 Plan Recommendations for Recycling, Bioconversion, and Markets
2009 Plan Recommendation Status
Recycling
Develop County policies or ordinances that
mandate certain actions be taken to improve
recycling rates.
In 2016, via Resolution 709-16, the County Council requested the
Departments of Environmental Management and Research and
Development initiate a feasibility impact study related to
extended producer responsibility and incentives. The request was
not implemented due to staffing and financial constraints.
Establish a differential tip fee ordinance. In 2005, Ordinance 05-27 adopted a 25 percent of the landfill
disposal fee for green waste and acceptable organics [green waste
must be separated from other solid waste to qualify for the
discounted disposal fee]. This was formerly codified in 2015 as
HCC 20-49(a)(2)(B) and implemented on July 1, 2015.
Establish an ordinance that mandates source
separation and recycling.
Difficult to achieve a balanced community-supported outcome in

dwellings and multi-tenant commercial
buildings to have recycling services.

2009 Plan Recommendation Status
Improve signage at recycling and transfer
stations.
The FY 2018–19 Recycling Program Educational Outreach
Consultant Scope of Services includes the redesign of new signage
at recycling and transfer stations. The signs were installed at the
recycling and transfer stations.
Reconfigure the East Hawaiʻi Regional Sort
Station Reload Facility for use as a material
recovery facility.
Changed goals and direction. County will use the existing facility
as a transfer station with limited separation.
Construct a new material recovery (bailing and
storage) facility for West Hawaiʻi.
The County no longer plans to develop a material recovery facility
in West Hawaiʻi.
Allow small businesses to use the recycling and
transfer stations to recycle select materials.

ordinance to amend County code.
Modify the operating permits of the recycling
and transfer stations to accommodate
expanded recycling services.
Current operating permits allow more materials to be recycled
when and if funding becomes available.
Hire one full-time staff member to serve as a
commercial recycling specialist. No funding available for this position.
Expand business education and outreach
programs. No funds allocated for this project except to provide information
on the website.
Expand opportunities to recycle in public areas
and during public events. The SWD offers recycling bins for events.
Install recycling bins in parks and other public

areas; however, most have been damaged or removed, and many
of the recyclables are diverted by individuals seeking income
through recycling (e.g., HI-5 program).
Conduct additional recycling events within the
community each year. Did not implement, limited staff. County has reduced the type of
materials accepted due to market constraints (e.g., certain
plastics).
Implement and expand the Recycling Art

Develop an organics composting facility at the
West Hawaiʻi Sanitary Landfill or other sites.
The County has been actively engaged in planning for a
composting facility. An Environmental Assessment (EA) was
developed for a proposed site at a former rock quarry adjacent to
the South Hilo Sanitary Landfill, and was withdrawn from
consideration due to concerns over the location and the potential
impacts to the local community. An EA was then completed for a
compost facility on 40 acres in the Shipman Industrial Park in
Kea‘au, and land procurement for 20 of the 40 acres is currently
being negotiated. Design work is currently being completed for
the facility and the composting facility is slated for operation
during the early part of the 10-year implementation period.
Investigate opportunities for pilot food waste
demonstration projects.
Did not implement.
Marketing
Enhance local markets for recyclable materials. The County encourages state or on-island reuse and end- markets
for recycled materials. Currently, green waste, glass, paper, and
tires are used locally.
4.3 Existing Conditions
According to the County Department of Environmental Management (DEM), the waste diversion rate,
signifying the quantity of recycled materials taken as a percentage of total waste generation, has
decreased from approximately 36.1 percent in FY 2009–10 to 20.8 percent in FY 2017–18. Exhibit 4-2
provides yearly data of waste generation, recycling, and disposal activities.
The FY 2016-17 diversion rate may be divided into categories to characterize the amount of recycling
and disposal by material. The two highest waste diversion rates occur in green waste and metal
recycling, at 63.3 percent and 14.2 percent, respectively.
Although the FY 2017–18 current diversion rate is 20.8 percent, there is likely a significant amount of
recycling being conducted independently by private businesses that is not being tracked or measured by
the County. These recycling efforts from the private sector significantly increase the overall diversion
rate, especially in the paper and plastic waste categories.
The status of recycling, bioconversion, and marketing efforts in the County of Hawaiʻi is described
below. As described in Chapter 2, scrap metal recycling facilities contracted with the County were
required to clear-out their stockpiles prior to permit expiration. With the facilities no longer in
operation, the County limited the scrap metal they would accept and diverted scrap metal to the private
sector–thus, there is a marked decrease in subsidized scrap metal after FY 2012–13. Therefore, although
2019 Integrated Solid Waste Management Plan Update
County of Hawaiʻi
August 2020 4-5
the recycling and diversion rates appear to have decreased, this number is skewed since most scrap
metal recycling was diverted to the private sector starting in 2013.

Note: The table does not account for non-County-sponsored (private) recycling or diversions. These could include “big-box” stores (e.g.,
Costco, Walmart) that ship combined bales of cardboard and plastic to either the West Coast to third-party brokers or to the
retailer’s distribution center. Contractors or nonprofit groups also sell recycled materials directly to brokers on the mainland.
4.3.1 County of Hawaiʻi/State of Hawaiʻi Programs
The County offers recycling services through various state and county programs. The County utilizes
recycling and transfer stations as collection points for the majority of recycled material from residents.
Recycled material accepted at these locations includes paper products, green waste, scrap metal, metal
cans, glass, and redeemable beverage containers through the State of Hawaiʻi Beverage Container
Deposit Program. Mixed recyclables and glass are placed in separate bins through the 2-bin program.
The County has also implemented the following measures:
•Maintains a limited number of recycling bins in some parks and public areas; however, most
have been damaged or removed.
•Provides technical assistance and bins to event coordinators looking to recycle at major events.
•Manages programs and facilities for green waste and composting.
To encourage recycling and bioconversion activities, the County provides public education and
awareness programs for residents. These education programs are discussed in Chapter 5 Public
Education and Information. Recycling also encompasses proper diversion of household hazardous
wastes, household appliances, and electronics; these programs are discussed in Chapter 6 Household
Hazardous Waste and Electronic Waste. Special Wastes, which require special handling or processing,
are discussed in Chapter 7.
2019 Integrated Solid Waste Management Plan Update
County of Hawaiʻi
4-6 August 2020
4.3.1.1 County Recycling and Transfer Stations
The County operates 22 recycling and transfer stations for residents to drop off garbage and at 18 of
those stations, residents can drop off recyclables. The Ocean View Recycling and Transfer Station,
located in West Hawaiʻi, is the most recent addition, and accepts HI-5 containers; however, it does not
accept 2-bin recyclables. Most of the recycling and transfer stations have a 2-bin recycling area. One bin
is for corrugated cardboard and brown paper bags, and the other bin is for container glass (non HI-5
such as wine and liquor bottles). Several of the recycling and transfer stations also accept metal cans
(food type) with the scrap metal, and a few collect newspaper. Some of these recycling and transfer
stations also serve as collection points for other types of recyclable materials.
Exhibit 4-3 lists the recycling and transfer stations and
the materials accepted at each location.
The County has expanded recycling activities at recycling
and transfer stations by expanding recycling and reuse
centers (RRCs) at various recycling and transfer stations.
The Kea`au Recycling and Transfer Station, was the first
to be developed into a full-time recycling and reuse
center. These centers have been developed at the Hilo,
Kealakehe, Pāhoa, Waimea, Laupāhoehoe, Keauhou, and
Wai`ōhinu recycling and transfer stations.

4.3.1.2 HI-5 Beverage Container Deposit Program
The State of Hawaiʻi enacted a new Beverage Container Deposit Program in late 2004. Otherwise known
as the “Bottle Bill,” a 5¢ redeemable deposit is placed on each beverage container, as defined under the
law. Consumers may then return the container to redeem their 5¢ at any redemption center. Other
details of the program include the following:
•A 1¢ non-refundable container fee is assessed for program administration.
•Redeemable containers are marked with a “HI5¢” or “Hawaiʻi 5¢” label.
•The container size is limited to 68 ounces (2 liters) or smaller.
•The beverage type consists of non-
alcoholic drinks (soda, water, coffee,
tea, juice) and limited alcoholic drinks
(beer, malt beverages, mixed spirits,
and mixed wine).
•The container material includes
aluminum, glass, bi-metal, and plastic
(#1 and #2 only).
In 2009, the HI-5 program’s state redemption
rate reached a high of approximately 79 percent representing 705 million containers. In FY 2015, the
County had about a 68 percent redemption rate representing 647 million recycled beverage containers
(HDOH 2015). In FY 2017, the County’s estimated HI-5 redemption rate reached approximately
87 percent representing approximately 117 million containers, down from about 89 percent the
previous year (County of Hawaiʻi DEM 2017a).5
5 The redemption rate is estimated using data from HDOH on the number of deposit containers redeemed divided
by the number of containers sold on the Big Island during FY 2017 based on the de facto population.
2019 Integrated Solid Waste Management Plan Update
County of Hawaiʻi
4-8 August 2020
The County provides Certified Redemption Centers (CRCs) for consumers to redeem their HI-5 beverage
containers at select recycling and transfer stations (see Exhibit 4-3 for locations). Additionally, the
County loans out recycling bins for collection of HI-5 beverage containers to organizers of any public
event. The recycling bins consist of an easy-to-transport, lightweight steel frame that uses a clear bag to
hold HI-5 beverages. The County-supplied recycling containers are secured by reservation and
availability is on a first-come, first-served basis.
4.3.1.3 Redemption Centers
Since June 2015, CRCs were opened to the public in the State of Hawaiʻi. In 2019, the County had about
20 CRCs in operation throughout the island. Segregated rates allow consumers an efficient method of
redeeming container refunds by weight (lb) instead of hand counting. Rates are set by the HDOH.
However, consumers also have the option of redeeming their containers by hand count; CRCs must hand
count hauls of 200 or less containers upon the request of the customer.
Exhibit 4-4 illustrates the Office of Solid Waste Management’s last update to segregated rates by
material type.

4.3.1.4 Green Waste Mulching and Drop-off Opportunities
In 2008, the County passed a resolution for an ordinance that prohibits paper and compostable organics
from the County Landfills by 2012 (Council Resolution No. 826-08). Thus, in 2016, the County contracted
with a private contractor to construct two mulch operation sites: East Hawaiʻi Organics Facility (EHOF) in
Hilo and West Hawaiʻi Organics Facility (WHOF). During FY 2016–17, a Notice to Proceed was approved
for the construction of these facilities through a private contractor, and they are now fully operational.
EHOF is located on Ho‘olaulima Road, which also leads to the East Hawaiʻi landfill and other County-
operated solid waste management facilities. WHOF is located in Pu‘uanahulu, adjacent to the West
Hawaiʻi landfill.
Residential customers may self-haul their organics to green waste bins at County recycling and transfer
stations (see Exhibit 4-3 for County-managed green waste recycling locations) free of charge. Residential
self-haul is restricted to 5 cubic yards or less and under 20,000 gross vehicle weight (GVW) with a
maximum of one load per day. For loads greater than 20,000 GVW or that surpass 5 cubic yards,
customers are routed to either the EHOF or WHOF. These facilities accept yard waste and untreated
wood pallets. Commercial entities, including landscapers and haulers, businesses, and government
agencies are required to dispose of their green waste at the EHOF or WHOF (County of Hawaiʻi DEM
2018a). These entities are charged a per ton disposal fee to offset expenses associated with green waste
handling and management, and must have a Solid Waste Facility Disposal Permit with an annual renewal
fee. The business fee is 25 percent of the MSW tipping fee at County-operated landfills.
2019 Integrated Solid Waste Management Plan Update
County of Hawaiʻi
August 2020 4-9
A minimum volume of mulch is available to residents for no charge, contingent upon availability. For
residential and commercial convenience, a mulch pickup area was added to the Kealakehe Recycling and
Transfer Station, in addition to mulch pick up
at EHOF and at WHOF. Mulch must undergo
the enhancement process before being
available for public use. This consists of a
minimum of 15-day processing of mulch,
wherein it undergoes a minimum of five
rotations held at a temperature of
131 degrees Fahrenheit to eliminate
potential invasive species or other unwanted
organisms (County of Hawaiʻi DEM 2018a).
The green waste program diverts green yard
waste and untreated wood pallet material
from the West Hawaiʻi Sanitary Landfill
(WHSL), and up until the end of 2019, the
South Hilo Sanitary Landfill (SHSL). In FY
2017–18, green waste comprised approximately 73 percent of all waste diverted from the landfills for
approximately 38,000 tons (County of Hawaiʻi DEM 2018b).
4.3.1.5 Scrap Metal
Scrap metal is often the bulkiest and heaviest material collected at municipal recycling and transfer
stations. Recycling scrap metal reduces tipping fees, conserves landfill space, and conserves natural
resources by replacing the need for virgin raw materials to produce new metal goods.
Residents may haul their scrap metal (ferrous and non-ferrous) to various County-operated recycling
and transfer stations (see Exhibit 4-3). No commercial, government agency, or nonprofit may use these
facilities to manage their scrap (Section 4.3.2.4 describes privately owned and operated facilities that
accept non-residential scrap). No automobiles, auto/boat/motor parts (including but not limited to
engines, motors, transmissions, or other metals with fluids), propane/oxygen/acetylene tanks, or other
compressed gas cylinders are accepted at recycling and transfer stations. The scrap metal is sorted by a
HDOH-approved contractor and sold to brokers for shipment in domestic and international markets.
To assist with the removal of abandoned vehicles, the County operates an Abandoned Vehicle Removal
Program. Under this program, abandoned vehicles may be hauled by a contractor to the Hilo or
Kealakehe Recycling and Transfer Station after certain procedures have been followed by the Hawaiʻi
County Police Department (HCPD) and DEM. Section 7.2.10 provides more detail regarding the
abandoned vehicle program.
In July 2007, the Hawaiʻi State Legislature enacted Act 197, which establishes new rules for scrap dealers
and redeemers to deter copper theft, a class C felony. The Act requires dealers to obtain a written
statement certifying the seller has the lawful right to sell the copper, and the seller must be 18 years or
older with valid identification. Paperwork received by the seller from the recycler must be notarized
before payment is issued. The County does not buy back copper. Section 4.3.2.4 describes private sector
copper recycling and redemption.
4.3.1.6 Tire Program
According to the State of Hawai’i, over 1 million new motor vehicle tires are brought into Hawaiʻi each
year with the majority being used to replace used tires and the remainder arriving on new vehicles
East Hawaiʻi Organics Facility (EHOF)
2019 Integrated Solid Waste Management Plan Update
County of Hawaiʻi
4-10 August 2020
(HDOH 2017). County Ordinance No. 07-182 (as codified in HCC 20-46) prohibits the disposal of tires that
are whole, cut, sliced, chipped, or shredded at any landfill and all island-wide recycling and transfer
stations. The County does not collect any tires at any recycling and transfer station or landfill. It is illegal
to drop off tires at any County facility. When consumers purchase a new tire, under HRS 342I-22, they
are also charged for its proper end-of-life disposal. Thus, tire companies are required to accept and
properly dispose of used tires from their customers. Currently, used tires generated in the County are
shipped to O’ahu for processing, either at H-Power or AES Hawai’i, Inc.
When left outside in the elements, old tires collect water and serve as breeding grounds for mosquitos
that carry various infectious diseases. In FY 2015–16, during the Dengue fever outbreak, the County
collected over 50,000 tires. Both County code and state statute are instrumental in the proper disposal
of old tires upon point of purchase.
4.3.1.7 Fats, Oils, and Grease Program
FOGs are accepted at the WHSL subject to a special handling fee. Restricted items include petroleum-
based oil, coolants, refrigerants, liquid paints and stains, and process water. Currently, FOGs are
accepted at various businesses listed on the County’s website on the green waste and motor oil web
pages. Residents can take limited quantities of household cooking oil to Pacific Biodiesel Logistics or
treat FOG waste at home, through solidification via absorbent materials such as kitty litter or
newspaper. Once solidified, this waste may be disposed of in the trash. Resources are also provided on
the County’s web page on how residents may convert their used oil into biodiesel.
4.3.2 Private Sector Programs
Many businesses in the private sector develop in-house recycling programs. These programs are often
not tracked by the County and may constitute a large percentage of recycled materials. Some larger
businesses have sophisticated systems to document the amount of recycled material generated, while
smaller businesses sometimes do not carefully track the amount of materials that they recycle. The
County plans to request data from the private sector to better understand the actual recycling numbers
on the island.
4.3.2.1 Curbside Collection of Recyclables
Businesses provide HI-5 beverage container redemption services at their business locations, community
centers, and schools, or through mobile redemption units. Contractors and nonprofit groups also pick up
paper products, such as mixed office paper, newspapers, and cardboard. The recycled materials are
generally sold to brokers on the mainland.
No island-wide or large-scale curbside recycling program is currently implemented in the County;
however, several companies offer collection of recyclables in limited areas of the County for both
business and residential customers. In addition to trash service, a few haulers are also providing
recycling collection service to their customers.
4.3.2.2 Large Retail Business Recycling
Large retailers, such as Walmart, Kmart, Costco, Home Depot, and others, maintain in-house recycling
programs at their stores. Cardboard and plastic (plastic bags and shrink wrap) constitute most of the
materials recycled at these large retailers. Recycling quantities may range from a couple of bales of
combined cardboard and plastic per week up to 20 bales per week for the largest retailers; each bale
averages approximately 800 to 1,000 pounds. Depending on the retailer, HI-5 beverage containers,
mixed paper, wood pallets, batteries, and light bulbs are also recycled at the stores.
2019 Integrated Solid Waste Management Plan Update
County of Hawaiʻi
August 2020 4-11
Data provided during interviews conducted with many of the retailers indicate that most of the
materials, especially cardboard and plastic, are shipped either to the West Coast to third-party brokers
or to the retailer’s distribution center. Other recycled materials are picked up by permitted haulers.
4.3.2.3 Green Waste
Green waste facilities on the island are primarily County-operated. Residents may dispose of their
organics at the six recycling and transfer stations that accept green waste if their volume is less than the
load restriction (see Section 4.3.1.4) and at the two organic facilities (EHOF and WHOF). The County also
promotes home “grasscycling” where grass clippings are used as fertilizer, along with backyard
composting where small-scale organics are converted to soil or mulch at residents’ properties. The
County promotes home composting on their website. To manage larger volumes and to increase their
diversion rate, a compost facility that can process food waste, wood pallets, paper, and compostable
plastics is planned for operation during the early part of the 10-year implementation period.
In 2016, the Hawaiʻi Department of Agriculture issued a permanent rule, pursuant to Hawaiʻi
Administrative Rule (HAR) 4-72-13, placing a quarantine on ōhi`a lehua (Metrosideros polymorpha) and
prohibiting the transport of all ōhi`a-containing materials to prevent the spread of ōhi`a-wilt disease, an
infection caused by the fungus Ceratocystis fimbriata and leading to the mortality of ōhi`a trees (Friday
et al. 2015). Because contaminated soil, sawdust, and wood are transmitters of this fungus, transport of
these materials is prohibited, unless under permit. Invasive species found in compost include little fire
ants (LFAs) and Coqui frogs (County of Hawaiʻi DEM 2018a). Thus, these organics must be treated under
an enhancement process to restrict the spread of invasive species and other organisms.
4.3.2.4 Metals Recycling
Businesses in the private sector with solid waste permits to collect and sort scrap metal at their facilities
include Atlas Recycling, Business Services Hawaii, and Big Island Scrap Metal on both sides of the island;
as well as Mr. K’s Recycling and Redemption in Hilo. Atlas Recycling and Mr. K’s Recycling and
Redemption are licensed to buy back copper. The metal is sold to brokers for markets in domestic and
international markets.
4.3.2.5 Tires
Multiple haulers collect and bale tires and tire parts for shipment to the West Coast or O`ahu for
processing into ground and crumbed materials for use as fuel at the H-Power waste-to-energy (WTE)
facility. One contractor repurposes tires to make concrete tire blocks used in decorative walls. The
contractor is currently attempting to gain approval from the State of Hawaiʻi to allow contractors to use
the tire blocks as a component in structural walls.
4.3.3 Current Material Markets and Market Development Initiatives
Only a small percentage of materials is processed and reused locally, and the cost of the County’s
recycling program is highly dependent on remote market prices for recycled materials in Asia. Therefore,
Hawaiʻi recyclers are susceptible to market fluctuations due to leaner profit margins originating from
high shipping costs, and in recent years, the downward trend in recycling market prices. For example, in
2018, China’s government implemented new restrictions on what type of recyclables may be imported
into the country. China no longer imports low-grade plastics and unsorted paper. China also aims to
increase the quality of recyclables entering China by requiring low contamination. Although the Asian
market is in flux, the United States’ recycling rate for polyethylene terephthalate (PET #1) plastic bottles
2019 Integrated Solid Waste Management Plan Update
County of Hawaiʻi
4-12 August 2020
increased from approximately 28 percent in 2016 to about 29 percent in 2017. This indicates the
demand is strong enough to continue recycling this product, which is mostly used in textiles and bottles.
With these uncertainties, the County has had to reconsider its target market and list of recyclable
materials according to Section 20-31, Chapter 20 of the HCC. On December 1, 2018, the County
eliminated #5 plastics (e.g., yogurt containers, margarine tubs), plastic grocery bags, and clam-shell-type
plastic (e.g., salad, bento boxes) in the mixed recyclable bins at the recycling and transfer stations. Maui
County has also stopped collecting these materials in response to China’s ban. Then in October of 2019,
the County ceased collection of plastic in their recycling program. The global markets for plastics had all
but collapsed. This did not affect the HI-5 beverage container program.
In comparison, Honolulu diverts 74 percent of waste from landfilling at their H-Power WTE facility
through incineration and energy recovery (HDOH 2015). During the development of the 2009 Plan, the
County did not intend to pursue this form of diversion because they agreed with Chapter 342G, HRS’s
definition that incineration does not constitute a form of recycling and considered it too costly to
implement. However, the County has not discounted the potential for some form of material recovery
and treatment for future implementation (see Chapter 9). With the onset of limited recycling
opportunities for plastics and mixed paper, the County will consider other opportunities for diversion
that does not discount an alternative material recovery system.
Examples of local and mainland markets are described below.
4.3.3.1 Mulch and Compost Products
Local businesses, including landscapers, contractors, and public agencies, use mulch and composted
materials produced locally. Customers use compost and mulch for both residential and agricultural
applications. It is likely that 100 percent of the materials produced through recycling of green waste can
be handled locally. The County offers mulch free to residents at EHOF and WHOF as well as the
Kealakehe Recycling and Transfer Station in the mulch pickup area. A new business in East Hawai’i offers
food waste collection service for composting. They also provide workshops for home composters.
4.3.3.2 Cooking Oil, Fats, Oils, and Grease
FOGs are accepted at the WHSL for a fee. Restricted items include petroleum-based oil, coolants,
refrigerants, liquid paints and stains, and process water. Currently, businesses can dispose of FOGs at
various locations listed on the County’s green waste and motor oil web pages. The County encourages
residents to treat FOG waste at-home, through solidification via absorbent materials such as kitty litter
or newspaper. Once solidified, this waste may be disposed of in the trash. Resources are also provided
on the County’s website on how residents may convert their used oil into biodiesel.
4.3.3.3 Paper
Currently, much of the recycled paper and cardboard generated on the island is shipped to domestic and
international markets for reuse. Several local businesses accept newspaper for recycling and produce
shredded paper products used primarily by the local agriculture businesses. Businesses interviewed
indicated that 100 percent of the materials that they produce through recycling are purchased by local
farmers for use in growing and shipping of agricultural products and flowers.
4.3.3.4 Plastics
Some plastic containers (#1 and #2) are included in the HI-5 Redemption Program. As described in
Chapter 3, the County has enacted a Plastic Bag Reduction Ordinance, regulating plastic bag and
2019 Integrated Solid Waste Management Plan Update
County of Hawaiʻi
August 2020 4-13
polystyrene plastic products to reduce the volume of this material and thereby decrease landfilling and
pollution-associated costs. Number 1 and 2 plastics are baled and shipped to overseas markets.
4.3.3.5 Glass
Glass is being reused in the County and shipped off island for recycling. On island uses have included
crushing for use in local construction projects. Up to 10 percent of aggregate is replaced with crushed
glass for “glasscrete.” Other uses for crushed glass include landscaping, backfill, and drainage, among
other things.
Several smaller businesses in the County use recycled glass to produce artistic, architectural, or
educational products;
however, the market for these
products is somewhat limited.
The potential exists to develop
local markets serving the
construction industry that
would recycle most or all the
glass containers generated in
the County. Doing so would
require marketing and
promotion efforts, changing
specifications and regulations,
and developing additional
processing infrastructure.
Products such as glassphalt or
reflective materials used in signage could potentially be produced on the island, and require
development of infrastructure, equipment, and/or facilities to accommodate the manufacture of these
materials.
The HDOH administers a state-wide glass recovery program funded by an advance disposal fee (ADF).
The department collects a 1.5 cent fee per non-deposit container glass from those who manufacture or
import glass containers (excluding deposit beverage containers). Those who import or manufacture
fewer than 5,000 non-deposit beverage glass containers within a 1-year period are exempt from
payment of the 1.5 cent fee; however, are still required to register with HDOH. Exclusions from the
program include tempered glass containers, including drinking glasses, cups, bowls, plates, and ashtrays;
and/or glass containers holding less than 2.5 ounces intended for human consumption.
4.3.3.6 Metals
There are limited facilities in the County for processing scrap metal. The Kealakehe Metal Salvage Facility
closed in 2016 due to onsite lead soil contamination. The bulk of the scrap metal generated in the
County is shipped either to O`ahu for processing and subsequent shipment to the mainland, or directly
to Asian markets.
In the past half-decade, the price of scrap metal experienced a downturn (Lasky 2018), primarily
because the high cost of shipping to distant markets has affected its value. While the scrap metal market
is expected to increase in the following years (World Steel Association 2017), this market remains highly
variable and subject to fluctuations. In addition to shipping costs, factors such as tariffs and product
bans will also affect prices.

4.3.4 County of Hawaiʻi Staffing Levels
Successful delivery of local government waste diversion programs requires devoting an appropriate
amount of resources including staffing. The County has demonstrated its commitment to waste
reduction and recycling by assigning the following staff to County waste reduction and recycling
programs in the DEM:
•One FTE (full-time employee) recycling coordinator.
•Two FTE recycling specialists for the HI-5 recycling program.
•Three FTE recycling specialists.
4.4 Issues and Concerns
As described above, a number of recycling, bioconversion, and marketing activities have been conducted
in the County, including programs and initiatives by other organizations. Despite these efforts, the
County recycling rate hovers around 20 percent (County of Hawaiʻi DEM 2018c), which is well below its
2013 target of 80 percent. As described in 4.3.2, private sector recycling programs are often not tracked
and may constitute a large percentage of recycled materials. However, more could be done by the
County and waste generators to treat materials as resources and further reduce the volume of solid
waste delivered to the landfills. The need to implement additional programs and policies is further
established by the County’s commitment to maximize diversion.
4.5 Options for Improvement
Pursuant to HRS 342G-26, the following subsections provide an overview of various options that could
be implemented to improve recycling and bioconversion and solidify markets. These options were
developed based on successful initiatives implemented in other jurisdictions that may be applicable and
appropriate for the County. Note that the options focus on recycling and bioconversion – waste
reduction and reuse are discussed in Chapter 3, public education is discussed in Chapter 5, and
institutional approaches to collection service delivery (i.e., public versus private) is discussed in
Chapter 8.
4.5.1 Residential Curbside Collection and Processing of Recyclables
In this option, the County would collect recyclables from single-family residents or contract with a private
collection firm for the service. There is a wide variety of curbside recycling programs in use in North
America today. They can generally be grouped into two categories: multi-stream or single-stream systems.
A third type, co-collection, in which bags of garbage and recycling are collected in a single vehicle, is
becoming less popular because of contamination concerns and low participation rates. Multi-stream and
single-stream recycling and other important considerations are described below.
4.5.1.1 Multi-Stream Recycling
With multi-stream systems, households separate and place recyclables into rectangular containers,
bags, or bundles and place them at the curb. The collector lifts materials by hand into multiple
compartments on the collection vehicle. Glass is often separated from other materials to avoid high
contamination of fiber and fiber processing difficulties that can result when broken glass is present.
Most programs sort materials into two or three types of commodities, and five to seven material sorts
are done in some programs.
2019 Integrated Solid Waste Management Plan Update
County of Hawaiʻi
August 2020 4-15
According to a 2016 study, single-stream systems (also referred to as commingled systems) produce 25
percent system loss on average for all steps in the process (mixed recycling facility, processor, mill, and
end user). The losses from a system where all recoverable materials are collected separately from each
other are much lower, at about 5 percent. In a multi-stream recovery system, where most materials are
kept separate from each other at the point of collection, a far greater amount of material collected is
made into new products or used beneficially. If completely separated, conversion to new or beneficial
products can range between 90 and 99 percent [depends on the material, the level of contamination,
and the sorting and processing accuracy] (Ecology 2016).
Advantages
•Separating different types of materials generally results in higher quality recycled material and
thus higher market prices.
•Can raise consumer awareness that sorted materials are valuable resources.
Disadvantages
•Requires more effort by households to sort materials.
•Requires a higher level of effort by haulers, resulting in higher collection costs.
4.5.1.2 Single-Stream Recycling
Single-stream or “commingled” recycling is a system in which all dry recyclables are placed into a single
container. The container is oftentimes lifted using a hydraulic arm attached to a collection vehicle. This
automated type of system lowers collection costs. The lowest cost per ton of material recycled is typically
achieved by single-stream recycling with fully automated collection in which a single driver can collect
material from many stops without leaving the cab of the truck (see photograph below). In a single-stream
system, only around 75 to 80 percent of the collected materials are made into new products, with 20 to
25 percent landfilled or burned in incinerators or boilers [energy recovery] (Ecology 2016).
Advantages
•Generally results in the highest rate of diversion of materials from landfill.
•Simpler system for participants to use because all
materials are combined in a single bin and no sorting is
necessary.
•Lower cost per ton of material recycled because of
higher resident participation rates combined with
automated collection efficiency (lower collection costs).
•Results in fewer injuries to collection workers and
corresponding workers compensation claims because
no lifting or handling of materials is required.
Disadvantages
•Much higher contamination of recyclables; significant
effort is required to ensure that residents maintain material quality.
•Requires sophisticated materials processing facilities and equipment, as well as good
communication with processors and end-use markets to ensure that manufacturing (raw
material quality) requirements are met.
•Fully automated systems require higher initial and long-term capital costs because mechanically
complex trucks are needed that have more rigorous long-term maintenance requirements.

4.5.1.3 Service Standards
Curbside collection is generally offered on a subscription basis, or made mandatory for some or all
single-family residents within a jurisdiction. The County is predominantly rural in character with
relatively small urban and suburban areas in Hilo, Kona, Waimea, and a few other locations. Many of the
rural areas within the County have steep, unimproved roads not suitable for collection vehicles. Thus,
mandatory curbside collection for all County residents is likely to be impractical. Further, longer
distances between collection stops will occur in many of the geographically dispersed small communities
in the County. A voluntary subscription service, for which not all residents would sign up, would
potentially make the distance between collection stops even longer. For program cost efficiency, it is
recommended that this option include designated zones where curbside service would be mandatory.
For the purpose of developing diversion estimates, a rough analysis of housing units in the 2010 Census
Designated Places was conducted. The result was an estimate of 72,894 households (US Census Bureau
2010) that would be served by the program, which is about 84 percent of the estimated 86,778 occupied
single-family households in the County in 2017 (US Census Bureau 2018).
Collection frequency could be weekly or bi-weekly. Weekly collection generally is more costly, and can
potentially result in somewhat higher diversion from landfill. The collection frequency could be
evaluated during a pilot program and determined at a later date.
4.5.1.4 Processing
The processing requirements for the collection program would need to be determined. The economics of
material recovery facilities are characterized by substantial economies of scale. It is likely that the
County’s most cost-effective strategy is to bale single-stream recyclables and ship them to the mainland
for processing (as is currently done by a privately-owned facility with mixed recyclables collected at
County recycling and transfer stations). The resulting requirements for a County processing facility would
consist of a covered building with space to store incoming materials, one or more balers for densifying
materials, and equipment and facilities to load shipping containers for transportation to markets.
It is likely that one or more new processing facilities would be needed to support this program. The cost
of developing and operating several smaller storage and baling facilities would need to be weighed
against the costs and other impacts of trucks hauling materials long distances to a central facility. The
most likely locations for such facilities would be in East Hawaiʻi (Hilo), one in West Hawaiʻi (Kona), and
one in the Waimea area.
4.5.1.5 Other Considerations
There are a number of other factors that would be considered when evaluating curbside recycling:
•Collection is typically performed through a contracting mechanism with a private service
provider, although many cities and counties collect recyclables using municipal workers. This
decision would need to be made with state contracting laws in mind.
•There are many ways of organizing the collection of garbage, recyclables, and green
waste/organics. The program must be integrated with other collection programs. If curbside
recyclable collection were implemented in the County, it would be costly to collect both at
curbside and at all 22 of the County’s recycling and transfer stations.
•Pilot programs and consumer research would be conducted prior to full-scale implementation to
develop data that can be used to refine and tailor the program to the needs of the various
communities within the County.
•Education and promotion of the program would be critical to success.
2019 Integrated Solid Waste Management Plan Update

Diversion Potential. Curbside recycling has the potential to divert significant quantities of material from
County landfills. The extent of diversion could vary significantly depending on the type of program that
is instituted and other factors such as those presented in Exhibit 4-5. Some of the more successful
curbside recycling programs in the United States report collection rates of 800 to 1,000 pounds of
recyclable materials per participating single-family household per year. For example, in 2014, the City of
San Jose exhibited curbside collection of 894 pounds per participating household per year (City of San
Jose 2015), and Seattle reported dry recyclables collection of 1,086 pounds per participating household
per year in 2017 (Seattle Public Utilities 2017). Both jurisdictions have a single-stream system.

1 Materials kept separate; common for large-scale commercial recovery and residential drop box locations or buyback centers.
In FY 2016, 14,887 tons of dry recyclables were collected from County recycling and transfer stations
(County of Hawaiʻi DEM 2017a), which is approximately 408 pounds per household per year. Using
results from the County’s 2008 waste composition study (Appendix D), assuming 72,894 households
(US Census Bureau 2018) would be served and material capture rates of 80 percent for most recyclables
(such as paper, cardboard, and containers), a curbside recycling program could result in additional
recycling of 11,910 tons, which is about 327 pounds per participating household per year, or about 735
pounds per participating household per year, including materials currently being collected from County
recycling and transfer stations.
Cost Considerations. The cost of curbside recycling ranges significantly for different programs. Factors
that influence costs are similar to those that affect the amount of recycling such as:
•Costs increase with the frequency of collection (for example, weekly versus bi-weekly). In a
study conducted by the Solid Waste Association of North America, switching from weekly to bi-
weekly service can result in a 20 to 40 percent decrease in cost (California Recycle 2016). A 2014
cost-benefit analysis from the City of Austin revealed that switching from weekly to bi-weekly
trash collection resulted in a cost savings of approximately 33 percent for customers (City of
Austin 2015).
•Subscription versus mandatory service (mandatory collection has a higher total cost and lower
cost per household because the travel distance between stops is reduced).
•If recyclable materials are separated versus single-stream, more collection time is required at
each stop, thus increasing costs for collection.
•Cost of recycling-only versus a program that also includes curbside collection of garbage and/or
organics.
•Costs are higher in more rural service areas (because of longer distances and increased travel
time between stops).
•Shipping costs increase with distance to markets.
•Unstable recyclables market.
2019 Integrated Solid Waste Management Plan Update
County of Hawaiʻi
4-18 August 2020
Information about the extent to which various factors affect the cost of recycling is shown in Exhibit 4-6.
The EPA reports that typical costs for curbside recycling range from $2.70 to $4.90 per household per
month (EPA 2016d). However, costs can be considerably higher depending on the contracted hauler in
the area and whether they own or operate a landfill or recycling and transfer station. All these costs
assume that there is a curbside garbage service in place. Should the County implement curbside
recycling in the absence of curbside garbage or green waste collection, costs would be considerably
higher because administration, billing, overhead, vehicle maintenance, training, and other costs would
be applied only to recycling and would not be spread over the cost of multiple services.
However, as illustrated in Exhibit 4-6, in a study conducted in Ontario consisting of 223 provincial
municipalities over a 10-year period, curbside operating costs are affected by various impact
parameters. For instance, while single-stream recycling exhibits 50 percent lower management costs
than multi-stream systems, single-stream systems also show 49 percent higher operating costs and a 9.6
percent lower market price for recyclables (Lakhan 2015). The County might consider similar factors
when determining the feasibility of a curbside program.
Exhibit 4-6. Factors Affecting Curbside Recycling Costs
Program Feature
Cost
Increase or Decrease
Single Stream (Program Implementation by 1 Municipality) $4,101 to $5,122 increase
Curbside Collection $9,888 to $11,586 increase

$1.20 to $4.80 increase
Population Density per Square Kilometer $44 to $58 decrease
Source: Lakhan (2015)
As discussed above, the cost of curbside recycling could vary significantly. A curbside recycling-only
system, without garbage or yard waste, and including material processing and marketing, would require
development of significant collection infrastructure and would be costly. The costs would likely be
significantly less if the service was combined with curbside garbage and/or organics collection.
4.5.2 Increase Green Waste Drop-off Opportunities at Recycling and
Transfer Stations
As discussed above, green waste can be dropped off at EHOF and WHOF, and the Kealakehe, Ke’ei,
Waimea, Kea’au, Pāhoa, and Volcano recycling and transfer stations. This option would increase the
number of recycling and transfer stations that accept green waste.
Diversion Potential. The operation of EHOF and WHOF, together with the acceptance of green waste at
various recycling and transfer stations, has resulted in an organics diversion rate of 73 percent of all
waste diverted from the landfill for approximately 38,000 tons in FY 2017-18 (County of Hawaiʻi DEM
2018c). Additional quantities could be captured with the implementation of a green waste disposal ban,
by allowing small commercial customers to participate in the program, and by expanding green waste
collection to include food waste.
2019 Integrated Solid Waste Management Plan Update
County of Hawaiʻi
August 2020 4-19
Cost Considerations. The existing EHOF and WHOF will have continued operational and monitoring
costs, which will be in part offset by tipping fees. The introduction of a collection system for food waste
will also increase operational costs.
4.5.3 Residential Green Waste Collection and Processing
In this option, the County would collect green waste from single-family
residents or contract with a private collection firm for the service. The
choice of County collection versus private collection would need to be
made with State contracting laws in mind.
In this type of program, materials are typically collected in bags or plastic
bins provided by residents or the local government. Types of bags or
containers and associated advantages and disadvantages of each type of
container follow.
•Plastic bags. Relatively inexpensive, convenient; however, a
significant problem for processors because the cost of removing all plastic from the organics
results either in contaminated low-quality feedstock, extremely high-cost bag removal methods,
or both. Grass in plastic bags can go anaerobic and become odorous when opened at the
compost facility. Most green waste collection programs now prohibit collection of green waste
in plastic bags.
•Compostable bags. Somewhat less convenient than plastic bins and
expensive over the long term for households, which is likely to lower
recovery rates. The bags compost well and avoid the contamination issues
associated with plastic bags.
•Plastic bins. Most programs now use plastic containers provided by the local
government, or in some cases by the user, and use rolling 30- to 90-gallon
carts that are easier to get to the curb than non-wheeled bins.
Bin contents are either loaded by hand (manual) or hydraulically (semi- or fully-automated) into the
truck. Most programs use trucks equipped with hydraulic loaders to limit lifting by collection workers,
thus reducing injuries and workers compensation claims.
4.5.3.1 Service Standards
Like curbside collection, it is recommended that any green waste collection program be a mandatory
program for densely populated single-family neighborhoods to increase efficiency and reduce operating
costs. Further, it is recommended that the program include rolling carts loaded by using semi-
automated or fully-automated equipment.
4.5.3.2 Processing Requirements
The County currently has a successful mulch program at East Hawaiʻi Organics Facility (EHOF), West
Hawaiʻi Organics Facility (WHOF), and residential haul to certain recycling and transfer stations (see
Exhibit 4-3). Mulching produces a relatively low value product that is less desirable than compost or soil
products made from compost. Thus, mulch is available for free to residents at EHOF, WHOF, or
Kealakehe Recycling and Transfer Station (a nominal charge for assisted loading may be instituted). The
County is also in the process of developing a compost facility that can process both green waste and
food waste. After the compost facility is operational; the County would conduct a cost-benefit analysis
2019 Integrated Solid Waste Management Plan Update
County of Hawaiʻi
4-20 August 2020
of coupling curbside green waste collection with existing method of self-haul to EHOF, WHOF, and
recycling and transfer stations.
4.5.3.3 Other Considerations
The other considerations that apply to curbside recycling also apply to curbside green waste:
•A decision would need to be made if collection would be provided by County workers or under a
contract with a private service provider consistent with State contracting laws.
•The program must be integrated with other collection programs and with the current green
waste services provided at County recycling and transfer stations.
•Pilot programs and consumer research would be conducted prior to full-scale implementation to
develop data that can be used to refine and tailor the program to the needs of the various
communities within the County.
•Education and promotion of the program would be critical to success.
Diversion Potential. As discussed previously, green waste can be dropped off at EHOF and WHOF, and
the Kealakehe, Ke’ei, Waimea, Kea’au, Pāhoa, and Volcano recycling and transfer stations. Additional
quantities could be captured with the implementation of a green waste disposal ban, and by expanding
green waste collection to include food waste.
Cost Considerations. The factors affecting the cost of curbside recycling discussed above would also help
determine the cost of green waste collection. Costs would depend on the other curbside services
provided. For example, the existing garbage and recycling transfer system network will impact the cost
of curbside recycling and its associated disposal tonnage.
4.5.4 Add Food and Other Organics to a Residential Curbside Recycling
and Green Waste Collection Program
As described previously, the County is in the process of identifying a
compost facility site that would accept yard waste, untreated wood
pallets, food, acceptable paper, and acceptable compostable
serviceware. The facility would be constructed by a private contractor
through a contractual agreement with the County. The finished
product would be sold island-wide, with a minimum portion made
available free to the public. The compost facility would accept green
waste and untreated wood pallets initially and then transition into
accepting the food, acceptable paper, and acceptable compostable serviceware allowing time for the
County to develop a program for collecting these materials.
Throughout the United States, Canada, and elsewhere, many large and small communities with a
commitment to zero waste are modifying their waste collection programs to include food and other
organics such as food-spoiled paper, thereby converting to a three-stream system in which food and
other organics are collected along with garbage and recyclables either weekly or on alternative weeks.
Example cities include Kaua’i County, HI; Boulder, Colorado; and San Francisco, CA:
•Kaua’i County, HI: Adopted a zero waste resolution in 2011 and plans to achieve a 70 percent
diversion rate by the year 2023. Implementation of PAYT program has incentivized residents to
reduce their waste generation. Also, a volunteer organization, Zero-Waste Kaua’i, supports the
ban of materials such as expanded polystyrene (commonly called Styrofoam®), and advocates
waste reduction practices at outreach events and schools (County of Kaua’i 2018b).
2019 Integrated Solid Waste Management Plan Update
County of Hawaiʻi
August 2020 4-21
•Boulder, CO: A zero waste ordinance was developed in 2015 where all single-family
homeowners were required to subscribe to a waste hauling service by 2016, and where all
multi-family property managers had to provide proper waste disposal for tenants. This
ordinance also applied to businesses and stated that there must be proper signage on all bins
for recyclables and compostables. Boulder plans on achieving an 85 percent waste diversion rate
by 2025 (City of Boulder 2016).
•San Francisco, CA: The City plans to become zero waste by 2020; in 2012, an 80 percent
diversion rate was achieved. A mandatory recycling and composting ordinance was passed in
2009 where all residents and commercial businesses had to properly sort their waste in the
proper bins. In relation to residential curbside collection, the City enforces a program that
provides separate collection of single-stream recyclables, compostables, and trash in three
separate bins (EPA 2018a).
These systems require residents to learn new ways of managing food and other organics and program
managers must clearly communicate to residents what materials must go in each bin. Most of these
systems have a type of variable rate to encourage behavior that minimizes garbage. In general, after initial
pilot testing and consumer research, these programs have typically been well-received by residents.
Current research efforts are focusing on ways to increase participation by residents; many programs
report a 35 to 40 percent residential organics participation rate (Wake County 2014; SAFE 2016; Hennepin
County 2017). Recently, curbside organics recycling has proliferated. According to a waste characterization
study conducted by BioCycle of various cities in the United States, between 2009 and 2011, food waste
collection expanded by more than 50 percent (Yepsen 2011). In fact, cities such as Portland, Oregon,
which also employ a PAYT system, exhibited an organics participation rate of 72 percent in 2013 (City of
Portland 2014). Implementation of aggressive PAYT rates is one method communities are using to improve
participation rates.
4.5.4.1 Processing
Food waste programs require more sophisticated composting systems. Once food is added to the
organics stream, composting must be done with some type of covered system with managed air flows to
minimize odors and prevent unsanitary feeding by birds, rodents, and other vermin. See Section 4.5.9
for more information about processing systems appropriate for food and other organics.
Diversion Potential. Using results from the County’s 2008 Waste Composition Study, assuming 72,894
households would be served and a 50 percent capture rate of food and wet or food-soiled paper, it is
estimated that 20,232 tons of food and other organics would be collected. When combined with
recyclables and green waste, the combined system is estimated to result in additional diversion of
32,142 tons, or an amount equivalent to 16 percent of the 195,887 total tons of waste delivered to
recycling and transfer stations in 2016. When the 14,887 tons currently being recycled at recycling and
transfer stations are included, the program would result in an increase in diversion equivalent to
37 percent of total current waste delivered to recycling and transfer stations.
Note that this is considerably lower than the 50 to 70 percent diversion rates reported by other three-
stream programs. This is the result of the following two factors:
•Residents who live in multi-family dwellings and in very rural single-family dwellings would not
be covered by the three-stream program, they would deliver materials to the recycling and
transfer stations.
•The materials arriving at County recycling and transfer stations include materials rarely set out at
the curb by single-family residents on a routine basis, such as construction and demolition debris.
2019 Integrated Solid Waste Management Plan Update
County of Hawaiʻi
4-22 August 2020
To make an equivalent comparison to other residential communities, the diversion rate was adjusted for
these two factors. Including only the 72,894 participating households and typical curbside commodities,
the three-stream system could result in an estimated diversion of 68 percent.
Cost Considerations. Rates for three-stream collection service depend on the size of containers residents
subscribe to. As examples, San Francisco and Seattle charge approximately $45 per month for service
with 32-gallon discard and organics carts (City and County of San Francisco 2018; Seattle Public Utilities
2018); costs are higher if larger containers are desired. These costs include disposal,
processing/composting, administration, education, and other costs, including the cleanup and long-term
monitoring of closed landfill sites.
4.5.5 Add Food Waste Bins at Recycling and Transfer Stations
Around the United States, local governments are adding food waste bins to their drop-off facilities:
•In 2010, numerous counties in Twin Cities, MN, enacted food waste programs. Hennepin County
has combined their food waste collection locations with recycling and transfer stations
(Hennepin County 2018). Other counties in the area, such as Anoka and Ramsey counties, have
certain drop-off locations dedicated solely to residential food waste (Anoka County 2018;
Ramsey County 2018). Minnesota state law (HF403-SF383) requires yard and organic waste to
be disposed of in a compostable or Kraft paper bag, or in a reusable container.
•In Brown County, WI, a pilot program is being run where participants may bring their food waste
to one of two drop-off locations. Residents must register with the County to use these locations
for tracking purposes (Brown County 2018).
According to BioCycle’s annual report, in 2017 there were 67 drop-off programs located in 15 states
servicing approximately 6.7 million households. The report also included a survey where 25 out of 30
municipalities stated that they considered their program a success (BioCycle 2017).
Source: Ramsey County (2018). Organics recycling.
The County currently has green waste (yard waste, untreated pallets) bins located at six County-
operated recycling and transfer stations. The County is currently considering the best-suited location for
a composting facility that will not only process green waste, but also food waste. The County is
investigating the possibility of accepting soiled paper among other compostable materials. Once
constructed, food waste bins could be added to recycling and transfer stations with existing green waste
bins. The contract with the current licensed hauler of green waste would then be modified to add food
waste to the collection agreement.
2019 Integrated Solid Waste Management Plan Update
County of Hawaiʻi
August 2020 4-23
To address odor and contamination-related concerns, certain practices would be implemented by the
County and program participants (Exhibit 4-7). The County could also consider legislation restricting the
type of compostable bag that may be disposed of in the food waste bins. For instance, legislation could
mandate that residents use a certified compostable bag for disposal at drop-off locations, according to
the U.S. Standard ASTM D6400 specification, similar to Minnesota (HF403-SF383) or California (AB1972-
SB567) state law. Recycling and transfer station attendants may determine if a bag meets this
specification by looking for a Biodegradable Products Institute (BPI) logo on the bag (Biodegradable
Products Institute 2018). If the bag does not contain this logo, or if it is not a Kraft paper material,
attendants may deny disposal of these uncertified bags into the food waste bins. By limiting
contamination in the organics, the ultimate quality and processing of the compost will be significantly
improved. To be effective, the program will require rigorous educational and promotional efforts,
particularly at the onset.

The County may consider running a pilot food waste program similar to that in Brown County (Brown
County 2018). As part of the program, the County could formulate a recording system for the food waste
bins. At the recycling and transfer stations, participants who wish to deposit organics in the food waste
bins would be required to sign-in with the onsite
attendant. Thus, data pertaining to usage
frequency would be ascertained.
To launch the program, the County could hand out
a limited supply of countertop compost bins and a
roll of BPI-certified compost liners to residents on
a first-come, first-served basis, contingent upon
funding availability. As stated in Chapter 5, Public
Information and Education, the County plans to
expand signage at recycling and transfer stations.
As part of this initiative, visually enticing signs
could be added near food waste bins. Also stated
in Chapter 5, the County plans to update their
public information brochures. A brochure could be
formulated illustrating acceptable and
unacceptable items that may be placed in food
waste bins. These brochures could also be handed
out at the recycling and transfer stations and at
public outreach events.

Diversion Potential. With many residents already accustomed to participating in an organics program,
there is the potential for increased diversion of food (and other compostable products), particularly if
introduced as a pilot program where residents are already accustomed to hauling green waste (e.g.,
Kealakehe). After understanding functionality, additional quantities could be captured by increasing the
number of recycling and transfer stations that accept food and other compostable products, and the
implementation of a green waste and food waste disposal ban.
Cost Considerations. The addition of food waste bins will have associated maintenance, transportation, and
processing-related costs. However, by adding food-waste bins to recycling and transfer stations with existing
green waste bins, the County will reduce transport-related costs and maximize efficiency for haulers.
4.5.6 Source Separation Ordinance (Mandatory Recycling) and/or
Disposal Bans with Differential Tip Fees
A growing number of local governments are adopting policies and legislation that prohibit disposal of
recyclable products and/or mandate source separation and/or recycling of those materials. For example,
in 2014 Honolulu mandated that commercial businesses and government recycle. Bars were required to
recycle glass, restaurants to recycle food waste, and businesses to recycle paper. In 2017, compliance
rates in Honolulu ranged from 74 percent for glass, 64 percent for office paper, and 74 percent for food
waste (City and County of Honolulu 2018a). In California, state law requires businesses that generate 4
or more cubic yards of waste per week and multi-family complexes (5 or more units) implement
recycling programs. They are also required to recycle their organic waste (e.g., food scraps, yard waste).
In support of the program, Salinas Valley Solid Waste Authority provides free waste assessments to help
these entities improve their recycling programs. Because of the commercial recycling mandate,
Greenfield, located in Salinas Valley, exhibited a 152 percent increase in recycled material by the end of
2010 (Institute for Local Government 2011).
Once recycling opportunities for select materials are in place, some policies the County could consider
include the following:
•Require residents and businesses to participate in recycling and composting programs. An
ordinance could be developed that either requires residents and businesses to source-separate
recyclables or bans the combination of designated recyclable or compostable materials with the
garbage.
•Ban readily recyclable and reusable materials and products from landfills and/or any future
energy from waste facility.
•Ban single-use disposable products from public events and festivals and as many other places as
possible.
According to the EPA (EPA 2018b), best practices to consider when formulating a recycling system
include:
•Incentives and penalties: Incentivize residents by implementing a PAYT system or via adding
additional payments.
•Separate compensation from rates: Allows contractors to base their fees on the number of
customers or cost of service rather than flat customer rates.
•Align costs to rates: Instead of funding for solid waste programs to occur primarily via tipping
fees, rates could be charged for commercial recycling and composting once the area reaches a
high diversion rate.
2019 Integrated Solid Waste Management Plan Update
County of Hawaiʻi
August 2020 4-25
•Limit or eliminate disposal payments: Limit or discard landfill or recycling and transfer station
contractor fees related to waste volume.
•Reward employees for more diversion: Train and reward workers for waste reduction
promotion.
•Require productive market use of yard debris and other organic materials: Require that organics
be composted at a compost or anaerobic digest facility, rather than being used as daily cover in
a landfill.
•Direct materials to local markets: Route recyclable materials for local use in the community on a
conditional basis.
•Education and outreach: Promote waste reduction efforts in-person, via social media, and via
proper signage and literature.
•Equal capacity commercial bin size and frequency: Provide equal capacity for recyclable and
compostable bins in comparison to waste bins.
•Equal services for multi-family customers: Contract with multi-family units and waste haulers to
provide equal services to that of a single-family resident.
•Source separation requirement or preference: Develop contracts that specify how recyclable
and compostable material are separated, based on the area.
•Purchasing preferences (Green Vehicles and Products): Develop contracts that include hauler
best management practices related to zero waste such as fuel-efficient vehicles or the use of
recycled plastic and paper products, etc.
•Innovations clause: Develop contracts to allow leeway in recycling programs for potential novel
disposal practices and technologies.
Diversion Potential. Most of the recycling and transfer stations have a 2-bin recycling area. One bin is
for corrugated cardboard and brown paper bags, and the other bin is for container glass (non HI-5 such
as wine and liquor bottles). Several of the recycling and transfer stations also accept metal cans (food
type) with the scrap metal, and a few collect newspaper. Green waste is also accepted at the facilities
listed in Exhibit 4-3. Thus, residents currently have the opportunity to recycle these materials.
These materials would be good candidates for inclusion in a source-separation ordinance or disposal
ban. Enforcement would be the main challenge because there is relatively little monitoring and no
enforcement authority currently in place at recycling and transfer stations. Prior to enacting the
ordinance, the County would conduct an extensive education and promotion program that highlights
the reasons for the ordinance and the recycling options available to residents. For a period of 6 months
to a year before enacting the ordinance, the County would have signage prominently displayed at each
station that announces the pending ordinance and clarifies recycling options.
Once enacted, it is recommended that initial enforcement be less stringent (that is, encourage, but not
strictly enforce compliance to minimize conflicts and the potential for illegal dumping). More strict
enforcement, such as fining those not in compliance, would require significant changes to the authority
and role of environmental management or security employees for the recycling and transfer stations, or
subcontracting this function to a suitable security provider. Such changes could be considered if less
stringent enforcement proves ineffective.
For the commercial sector, the County could consider a similar ordinance that would apply at its landfills
to readily recyclable materials such as cardboard, green waste, and metals. At its landfills, it would
accommodate the drop-off of all banned materials for recycling. Drop-off would be free (such as at the
2019 Integrated Solid Waste Management Plan Update
County of Hawaiʻi
4-26 August 2020
recycling and transfer stations) except the County could charge a fee for metals that is less than the fee
for garbage (the County started offering this to the commercial sector for green waste in 2015). This
differential tip fee would help encourage diverting metals to private recyclers. The ordinance could be
enforced by banning these materials from the landfill, with a penalty of two times the regular disposal
rate if loads are found containing the banned materials.
In 2009, Seattle mandated food and yard service for all single-family residents, and in 2010 the recycling
rate increased by 2.6 percent. In a 2005 survey, only 25 percent of Seattle residents used an organics bin
while in 2010, the utilization rate increased to 72 percent (Seattle Public Utilities 2017). Similarly, a
green waste and mulch ban from Guam’s one operating landfill in 2013 resulted in support from
residents, due to the multiple potential applications of compost in the agricultural and commercial
sectors (One Guam 2018).
Cost Considerations. To implement this option, the County would need to increase staffing and potentially
seek consulting assistance to research, and draft policies and legislation. Additional staffing would be likely
required to handle the additional material diverted from the landfill as well as enforcement.
4.5.7 Commercial Recycling and Green Waste Program
While there are some businesses and institutions that currently recycle, there is considerable
opportunity to increase recycling from the non-residential sector. Because current markets for most
recyclables are in Asia or the U.S. mainland, the cost of shipping recyclables to markets makes recycling
less cost-effective for businesses than it is in most U.S. mainland communities. It is likely that to increase
the rate of non-residential recycling, the County will need to take regulatory steps to drive the process.
Regulatory measures may include the following elements:
1.Mandatory Recycling/Source Separation Ordinance. Adopt a mandatory recycling ordinance that
requires all businesses and institutions to recycle an approved list of commodities. That list
could include cardboard, metals, green waste, and other select commodities.
2.Business Recycling at Recycling and Transfer Stations. Mandatory recycling could be expensive
for smaller firms that do not generate much waste (such as small offices or retail operations).
Thus, the County would change the permits that govern its recycling and transfer stations to
allow small businesses and institutions to drop off materials. Businesses would still be
prohibited from disposing of waste at stations. At stations where space is available, the County
could provide additional bins to accommodate small business recycling efforts.
If accommodating small business recycling at the stations is not acceptable or feasible, the
mandatory recycling ordinance would provide an exemption for businesses with less than a
certain threshold number of employees (for example, small businesses employing less than
20 persons).
3.Require Collection Firms to Provide Recycling Services through Licensure. License all garbage
collection companies with a condition of the license that stipulates they must provide an
approved recycling collection service. The required service would be tied to the list of
mandatory recyclables. If all firms are required to provide a recycling service, competition would
lead to competitive rates for hauling both recyclables and garbage.
4.Develop and Contract for New Processing Facilities. As discussed above for residential recycling,
the County would need to ensure that processing and marketing opportunities are available for
these materials. The same processing facilities could be used for residential and non-residential
recyclables. This would probably include the County issuing an RFP for these services either at
2019 Integrated Solid Waste Management Plan Update
County of Hawaiʻi
August 2020 4-27
County-owned sites and/or allowing contractors to propose sites. Facilities would probably be
needed in West Hawaiʻi, East Hawaiʻi, and possibly in the Waimea area.
This option would require significant outreach to the business community, as well as a marketing and
technical assistance program. The option would include a reasonable phase-in period so that collection
firms can ramp up for the changed requirements. The County could consider implementing an incentive
program and/or recognition program for businesses that meet the recycling requirements.
If this program is to apply to state and federal government institutions such as schools, negotiations and
consultation with agencies will need to take place. For schools, collection contracts would need to be
revised to allow for recycling in addition to garbage collection.
Diversion Potential. Using results from the County’s 2008 waste composition study, assuming 80 percent
of business and institutions would participate and a 60 percent capture rate for readily recyclable
materials and green waste, this program could result in additional recycling of approximately
13,400 tons per year.
Cost Considerations. The County would need to dedicate staff to draft ordinances and to follow through
with the required legislative process to enact them, and set aside funds for the promotion and
education of the program.
4.5.8 Bioconversion of Food and Other Organics from Businesses/
Institutions
The County’s 2008 waste composition study estimated that discarded food makes up 34,000 tons, or
16 percent, of disposal at County landfills. The putrescible nature of food requires more costly and
sophisticated collection and processing infrastructure than green waste; however, there are many
successful examples on the mainland and elsewhere of organics management programs that
incorporate food and other organics as feedstock. This option discusses the potential for collection from
non-residential sources.
All material would have to be treated under the
enhancement process to restrict the spread of invasive
species and other organisms. In 2016, a contract was
signed with Hawaiian Earth Recycling to operate a
compost facility that can process organics including food
waste. Thus, it is expected that the County will have an
established treatment facility to process incoming food
waste and other compostable materials from businesses
and institutions during the early part of the 10-year
implementation period. The County would need to take
the following steps to attract material to the facility:
•Price the tipping fee at the facility less than the
tipping fee at its landfills to provide a financial incentive for businesses to separate food.
•Develop an outreach program that would work with collection firms and major food generators
to encourage participation well in advance of the facility operation date.
•Be prepared to establish an ordinance preventing food from disposal at major food generators if
the first two steps above are not enough to attract material to the processing facilities.
2019 Integrated Solid Waste Management Plan Update
County of Hawaiʻi
4-28 August 2020
Diversion Potential. Food and other organics, such as waxed cardboard and wet or food-soiled paper,
could be collected from businesses and institutions that discard reasonably large quantities of food.
Existing hauling routes and schedules would need to be altered to provide a separate service for food
and other organics.
Businesses and institutions would need to change work practices to separate food and other organics
from garbage. Other communities have found that one significant challenge for businesses and
institutions has been finding space on the premises to set out a separate collection bin for organics.
Cost Considerations. The potential need for increased staffing to effectively communicate among County
staff, the collection company, and businesses and institutions.
4.5.9 Processing Food Waste Options
Compared to a green waste processing operation,
processing food waste requires additional design and
operational features to prevent odors and the attraction
of birds, rodents, and other vermin. This is typically
accomplished as follows:
•Receiving food scraps in an enclosure and
allowing biodegradation via earthworms
(e.g., vermicomposting)
•Receiving collection trucks and preparing/mixing
feedstocks in an enclosed building with biofilters
and other features to manage air flow and
odors.
•Mixing and agitating feedstock daily (unlike
green waste where under certain circumstances
material can be stored for days at a time).
Organic material may be heated to remove
potential invasive species and other unwanted
organisms, and to speed up the degradation
process.
•The bioconversion process requires either more
sophisticated electronic controls and/or more
sophisticated and meticulous daily operations. Many systems conduct this step of the process in
enclosed buildings or vessels. A brief overview of four commonly used bioconversion
technologies for food follows.
4.5.9.1 Covered Forced Air
Some relatively recent innovations have taken place to lower the cost of bioconversion with food. These
systems include engineered fabric buildings with aluminum frames, air control, and biofilters for receiving
and feedstock preparation. The buildings typically range in size from 2,000 to 10,000 square feet.
Once feedstocks are prepared, the material is placed into outdoor windrows with a fabric membrane
covers (for example, Gore or Ag-Bag) and aeration systems, or into roofed pole buildings with concrete
bunkers, aeration systems, and organic covers (typically finished product). After approximately 30 days,
the feedstock is cured in windrows or piles either outdoors or under a covered structure.

Bunker with roof (Latah Co., ID)
2019 Integrated Solid Waste Management Plan Update
County of Hawaiʻi
August 2020 4-29
These systems have lower capital costs than other systems; however, may require more knowledgeable,
experienced operators to maintain final product quality and minimize nuisance odors.
4.5.9.2 Bays, Beds, and Tunnels
Bays, beds, and tunnel systems are normally
constructed inside buildings, and are essentially a
variant of a turned windrow system. The feedstock
is placed either in a bay formed by two long
parallel walls, or in a four-sided reactor bed.
The walls of the bay or bed are generally about
6 feet high.
The material is turned down the length of the bay
or bed by a machine that is suspended above or
rides on rails along the top of the bay or bed.
Turning aerates the material, and additional
aeration may be provided by a forced air system in the floor of the bay or bed. The turning machine
gradually moves the material down the length of the bay or bed and is timed so that by the time the
material reaches the end, the primary composting process is largely completed. The product is cured in
turned windrows or aerated static piles. As with static piles, the mixture must be perfectly balanced
when it is added because there is no further opportunity for amendments to be added. However, odors
can be easily controlled because bays and beds are usually constructed inside buildings. Bays and bed
systems typically are more expensive than turned windrows and static piles; however, less expensive
than in-vessel systems.
4.5.9.3 In-Vessel Systems
In-vessel systems offer the greatest degree of
control over the composting environment. In-
vessel systems also have the smallest land
requirements, although they are the most
expensive technology to design, construct, and
operate. An in-vessel system is defined as one in
which the composting process is conducted inside
a type of sealed container (the vessel) where the
environment is highly controlled, and access is
restricted (may be aerobic or anaerobic).
In-vessel systems can be either flow or batch
reactors. Larger systems consist of permanent chambers installed within a building. Mechanisms are in
place to load raw waste into and to remove compost from the chambers. At a minimum, the system
includes monitoring systems for temperature and oxygen content and an aeration system. Smaller
systems involve the use of portable containers. Modular vessels, which are similar in appearance to
international shipping containers, are filled with raw organic waste, sealed, and attached to aeration
manifolds and monitoring equipment. Microbes biodegrade the material, and at the end of the primary
composting process, the container is disconnected, emptied, and the material is formed into turned
windrows or static piles to complete the composting process (curing). A common byproduct of the system
includes biogas that may be utilized as energy. The vessel is then available for the next batch of feedstock.

4.5.9.4 Energy Recovery with Wet and Dry Anaerobic Digestion
Significant amounts of energy are contained in food and other organics currently sent to landfills. The
Hawaiʻi Clean Energy Initiative seeks to generate 70 percent of Hawaiʻi’s energy from renewable sources
by 2030 (HDOH 2015). The variability in energy prices and concerns over global climate change have led
to the development of anaerobic digestion systems for food and other organics. Anaerobic digestion is a
proven technology that has been used in the wastewater field for years. The process converts food and
other organics to biogas (that can be used to produce electricity or to power vehicles) and dewatered
digestate that can be composted and sold for agricultural uses.
In a wet system, incoming materials are loaded into an enclosed building for tipping, pre-sorting, and a
series of pre-processing activities to remove recyclable and non-recyclable inorganic elements from the
material. Feedstocks are then fed into a hydropulper, which is designed to separate the remaining
inorganics from the biodegradable elements and to convert the organics into an organic suspension. The
biodegradable organic elements are pumped from the hydropulper to a grit removal system to further
remove unwanted materials that may have passed through the hydropulper sieve. The grit-free
suspension is then pumped to the anaerobic digester where the digestible material is converted into
methane-rich biogas. Non-digestible material is segregated for final curing and stabilization into compost.
Dry systems allow solid materials to be mixed into the
biomass, whereas traditional wet digesters make only
minimal use of solids. In a dry system, up to 50 percent
of the biomass can be solids such as green waste, wood
chips, or paper. Biogas is then transformed in block-type
thermal power stations into electrical energy and heat.
Like the wet system, the digestate residual is cured to
convert it into compost or other agricultural products.
The dry systems have the advantage of being relatively
cost-effective organics management solutions for
relatively small waste streams (as small as approximately
6,000 tons per year). A key to the cost
effectiveness of wet or dry systems is
proximity to a power user, and/or
relatively high prices paid for electricity
generation or fuels. The relatively high cost
of electricity in the County provides an
advantage for this technology locally
compared to other areas of the country.
Diversion Potential. Using results from the
County’s 2008 waste composition study,
and assuming capture rates of 50 percent
for food, 50 percent for wet- and food-soiled paper, and 10 percent for wood, this program could result
in additional diversion of 21,600 tons. Additional carbon may need to be obtained from green waste,
wood chips, or other sources depending on the type of processing system selected.
Cost Considerations. The cost of processing food wastes and other organics will vary depending on the
type of technology, market conditions, contract terms, permitting requirements, power purchase
agreements, and other factors.

4.5.10 Establish a County “Buy Recycled” Policy
This option, also discussed in the draft source reduction section, is important for promoting markets for
recycled materials. The County could change its procurement practices to require the use of recycled
glass, organics, and other materials to the extent practicable. This would help support the development
of local markets for readily recyclable materials. The County would work with local businesses to identify
materials that can be reused and recycled as part of County operations.
Diversion Potential. Difficult to quantify; this is a program that would support additional recycling.
Cost Considerations. The County may need to pay a higher price for some recycled products, and would
need to devote staff resources to refining its procurement policies.
4.5.11 Marketing Partnership with Other Hawaiʻi Counties
The County’s geographic isolation makes it expensive to ship recyclables to most existing markets. The
County could team with the other Hawaiʻi counties and the state government to investigate joint
marketing and market development opportunities. This could include improved pricing for backhauling
containers to the mainland and overseas markets, funding pilot programs for new local end uses, or
joint marketing of materials to improve market prices and/or lower transportation costs.
Diversion Potential. Difficult to quantify diversion potential; however, this initiative could result in long-
term benefits.
Cost Considerations. The County would need to dedicate additional staff to develop and participate in
potential studies or pilot programs.
4.5.12 Establish Opportunity to Recycle Legislation
The County could consider developing new requirements for owners and managers of multi-family
dwellings and multi-tenant commercial buildings that ensure that all tenants have reasonable access to
recycling services and premises-based facilities comparable to single-family dwellings and small
businesses. Any such requirements would be best implemented following consultation with the local
building industry.
Diversion Potential. Difficult to quantify diversion potential, however this initiative could result in long-
term benefits.
Cost Considerations. There would be some cost associated with industry consultation and modifying
building codes to support the new requirements. The cost of buildings affected by the legislation could
increase somewhat; however, after there is familiarity with the new requirements, impacts on
construction project cost would be modest.
4.5.13 Maintain Active State and Regional Profile on Zero Waste Public
Policy
The County could work with state and federal legislators and encourage other communities in the region
to adopt similar zero waste goals and plans. This effort could include a coordinated effort with regional
cooperation to support state and national efforts to adopt:
•Extended producer responsibility.
•Deposit programs.
2019 Integrated Solid Waste Management Plan Update
County of Hawaiʻi
4-32 August 2020
•Funding of zero waste initiatives through state-wide or regional landfill surcharges and product
charges.
•Change school collection contracts to include recycling.
•Full cost accounting for waste disposal.
•Packaging levies (for example, on plastic bags).
•Minimum recycled content standards for additional products.
•Design for the environment programs.
•Green procurement and green building guidelines for the public sector.
•National measuring, monitoring, and reporting in achieving zero waste goals.
•New mechanisms for financial assurance for post-closure liabilities for landfills.
Diversion Potential. Difficult to quantify diversion potential; however, this initiative would result in long-
term benefits.
Cost Considerations. There would be cost associated with staff time spent on zero waste advocacy, and
modest expenses for supplies.
4.5.14 Other Potential Recycling Opportunities
There are other initiatives that the County could adopt to support recycling, including:
•Improve Recycling Opportunities in County Parks. The County could consider developing a
program to provide additional recycling opportunities in all County parks. This could mirror the
2-bin system used at recycling and transfer stations by placing small mixed-material bins and
glass-only bins adjacent to all garbage bins at each park. The effectiveness and cost of this
program would first be tested with a pilot program. Improvements could include the addition of
lock-kits to recycling bins as well as improved illumination systems to deter vandalism.
•Improve Recycling Opportunities on Downtown Streets. The County Public Works Department
collects trash in downtown areas of communities such as Hilo and Kailua-Kona. A pilot program,
similar to the one suggested above for County Parks, could be implemented to test the
effectiveness and cost of providing recycling opportunities at all trash collection locations.
•Expand the Promotion of Event Recycling. The County currently provides technical assistance
and event bins to event coordinators looking to recycle at major events. This program could be
expanded by developing a list of major recurring events, contacting event coordinators, and
working with those coordinators to develop plans to improve recycling. The County would
consider providing financial assistance for recycling bins and/or developing an ordinance that
requires event recycling and possibly the use of compostable or reusable cutlery. The County
could also consider requiring waste reduction and recycling plans for event and facility rental
permits.
•Establish a Recycle Art Campaign. The County could establish a Recycle Art campaign, similar to
the Art of Recycling School Competition, with the goal of coordinating the efforts of business
and public offices and schools to organize and conduct recycle art contests at various venues
once per quarter. Examples of places where recycle art could be displayed include bank lobbies,
grocery stores, government offices, libraries, schools, airports, and museums. A good example
of the popularity of recycled art, “The Trash Show: Hawaiʻi Artists Recycle” has held annual arts
events that are free and open to the public in East Hawaiʻi for over 30 years.
2019 Integrated Solid Waste Management Plan Update
County of Hawaiʻi
August 2020 4-33
•Expand Visitor Industry Recycling. Hotels, resorts, and other businesses that service the County’s
visitor industry are major waste generators. The County could increase its efforts to work with
this sector to improve recycling opportunities.
•Explore Opportunities to Develop an Eco-Industrial Park. Eco-industrial parks are clusters of
complementary businesses that can make beneficial use of currently discarded materials and
products produced by others. Candidates are organics processing, building deconstruction,
salvage, reuse, and repair. Actions by the County could include passing favorable zoning
ordinances and/or tax relief to incentivize this type of activity.
4.6 Recommendations
Based on the analyses presented above and discussions with the SWAC, the Plan recommends the
actions listed below to improve the County recycling, bioconversion, and markets program. The
operating expenditures associated with the recommended actions would likely be funded by a new
funding method (e.g., PAYT), property taxes, and tipping fees, and the capital expenditures would be
financed by general obligation bonds as discussed in greater depth in Chapter 10 Administration.
The recommendations are divided into two categories, those relating to recycling of non-organic
materials (Recycling) and those relating to diversion of organics from landfills (Organics).
Implementation of the recycling recommendations may be slower than initially anticipated because of
the impact that the world-wide commodity market volatility has had on County recycling revenues.
4.6.1 Recycling
1.Develop County policies or ordinances that mandate certain actions be taken to improve recycling
rates. In many communities nationwide, experience has shown that updated policies and
ordinances are necessary to support new programs designed to treat discarded materials as
resources and keep them out of landfills. After reviewing various options, the County decided the
following options are best suited to the specific conditions within the County:
Thoroughly investigate mandates prior to implementation including assessment of markets
(should be well-established), operational viability (solicit input from recycling and transfer
station attendants, haulers, landfill operators), and implementation in other jurisdictions with
an emphasis on other Hawaiʻi counties.
Establish a differential tip fee ordinance.
Investigate the feasibility of establishing a mandatory curbside collection program for some
single-family residences.
Establish mandatory source separation and recycling ordinance, which would require all
businesses and institutions to recycle select types of materials. This could include implementing
landfill bans for select recyclables.
Develop legislation that requires owners and managers of multi-family dwellings and multi-
tenant commercial buildings to provide recycling.
Conduct research and coordinate with legislators and waste managers within Maui, Kaua’i, and
Honolulu counties, to evaluate the potential for combining efforts to develop a statewide landfill
diversion strategy.
Lobby the State to change school waste collection contracts to mandate that recycling services
are included.
2019 Integrated Solid Waste Management Plan Update
County of Hawaiʻi
4-34 August 2020
2.Complete capital projects to facilitate implementation of expanded recycling programs. A
common theme expressed during discussions with the SWAC is the need for improved facilities to
manage recyclables. The County plans to:
Modify infrastructure at recycling and transfer stations to accommodate and expand recycling.
Improve signage at recycling and transfer stations to provide the public with comprehensive
information about recycling opportunities and procedures.
3.Expand opportunities for commercial recycling. The results of the waste stream assessment
conducted for this Plan update (Chapter 2) demonstrated clearly that commercial businesses
dispose of large quantities of potentially recyclable materials. After deliberation with the SWAC and
reviewing programs implemented by other jurisdictions, the County could implement the following
actions to increase commercial recycling:
Allow small businesses to use the recycling and transfer stations to recycle selected materials
within limits manageable by the County.
Work with the HDOH Solid and Hazardous Waste Branch to modify recycling and transfer station
operating permits to accommodate expanded recycling services.
Expand education and outreach programs for both large and small businesses to foster
participation in commercial recycling programs.
4.Expand opportunities to recycle in public areas and during public events. Providing recycling bins in
public places and at public events is a very visible way for the County to demonstrate its
commitment to landfill diversion. The County could achieve this by:
Installing additional recycling bins in parks and other public areas.
Increasing recycling opportunities at community events..
5.Establish goals that are expressed and measured in terms of environmental impacts.
(e.g., greenhouse gas emissions, toxicity, energy use) and consider full life cycle impacts, in addition
to tonnage-based landfill diversion or waste recovery goals.
6.Annually or bi-annually assess existing local and regional markets for materials across the
waste stream; study service voids for missed opportunities to recover commodities. The County
could shape strategic action plans around the findings. This process would need to consider
community, environmental, and other factors; this would not just be a commodity-driven effort.
An initial assessment could consider other destinations for shipping recyclables that have lost
value in the current market. For example, the County could consider shipping formerly recyclable
materials (e.g., plastics) to the H-power facility in Honolulu if determined economically cost
effective (i.e., cost savings, cost neutral) through close coordination and negotiations with the
City and County of Honolulu.
4.6.2 Organics
Waste stream studies conducted previously and, as part of this project, have determined that organics
comprise a relatively large portion of the waste entering County landfills annually. Diversion of organics
was identified as a priority by the SWAC; therefore, the County developed the following actions:
1.Improve education and outreach programs that promote improved management of organics.
Composting has many benefits and is one area where education and outreach has been shown to be

County of Hawaiʻi

effective at reducing organics households and businesses send to landfills. After considering various
options, the County plans to implement the following education and outreach programs:
Ensure that the contractor responsible for administering the organics program is meeting
contractual requirements.
Expand and further develop a master composter program.
Develop a training program and guidance materials for farmers and gardeners.
Implement a “Stop Wasting Food” program that would benefit programs such as local food
banks.
Partner with others to establish compost demonstration gardens at recycling and transfer
stations or at other visible locations in the community.
2.Initiate an onsite composting program for residents and businesses by distributing subsidized
composting bins to both residences and businesses. Data from similar communities indicate that the
lowest cost method of keeping organics out of landfills is to manage them on site. This eliminates the
need for costly collection or transfer of organics. This is particularly true for the County with many
homes in rural areas that cannot be served cost-effectively by collection truck routes. This program
would fund subsidized bins for onsite composting of green waste and food waste.
3.Conduct a landfill organics ban implementation study.
4.Implement added organics management facilities and equipment. Although onsite programs are
beneficial, more centralized infrastructure is also needed to provide opportunities for those
residents and businesses that are not interested in managing organics on site. After reviewing many
options with the SWAC and other stakeholders, the County will consider the following programs:
Add food waste drop-off locations at recycling and transfer stations that already collect green
waste.
Formulate compostable bag ASTM D6400-compliance legislation.
Add organics/yard waste disposal to existing brochures/signage.
Expand the number of drop-off locations for green waste and/or food waste at recycling and
transfer stations.
Continue operation of mulch facilities at WHSL and SHSL.
Investigate organics collection programs, including a residential curbside collection program and
recycling and transfer station drop-off facilities. As part of this investigation, perform pilot food
waste demonstration projects with the potential for eventual expansion into full-scale food
waste management programs.

5.PUBLIC EDUCATION AND INFORMATION
5.1 Introduction
Public education is a critical component of a successful environmental program because it informs
citizens about proper solid waste management and diversion methods. The public’s understanding of
various reuse, recycling, and composting activities are improved through these education and outreach
programs. Education informs residents of the wide variety of solid waste services and opportunities
provided by the County and other entities.
This chapter describes existing public education activities within the County of Hawaiʻi, identifies current
issues and concerns with respect to public education, and presents recommendations that will help
enhance educational opportunities.
5.2 Background
5.2.1 Regulatory Context
In accordance with Hawaiʻi Revised Statutes Chapter 342-G (HRS 342G-26), the public education and
information section of an Integrated Solid Waste Plan shall describe the programs that will be used to do
the following:
1.Provide comprehensive and sustained public notice of the options for alternative source
reduction, recycling, and bioconversion, and for the proper handling of household hazardous
and special wastes.

5.3 Existing Conditions
5.3.1 County of Hawaiʻi Public Education and Information Programs
The County employs several recycling specialists who conduct basic educational activities along with
their other duties. In addition, the County contracts with several business entities to coordinate and
provide educational activities to the community. The County’s main education initiatives include the
following:
•Website (HawaiiZeroWaste.org).
•Newspaper advertisements.
•Radio, television, and movie theater advertising.
•Brochures/flyers/posters.
•Community outreach.
•Networking with existing nonprofit and community groups (e.g., Recycle Hawaii, Zero Waste
Big Island).
•Community events.
•Sporting events.
•School and group tours of the solid waste/recycling facilities.
•Business education (HawaiiZeroWaste.org).
•Person-to-person interaction (emails, telephone calls, interaction with customers at the
recycling and transfer stations).
A brief description of each of these initiatives follows.
5.3.1.1 County Website
The Department of Environmental Management, Solid Waste Division (SWD), has its own page on the
County’s government website. Two links are provided on the SWD’s dedicated page. The first link is to
the County Public Document portal, which directs the user to solid waste documents and standard
forms. The second link is for access to the SWD’s website, HawaiiZeroWaste.org. The public document
portal includes official solid waste documents and operational information, recycling and transfer
station locations and operating hours, guidelines, permits, and plans. The HawaiiZeroWaste.org website
is a comprehensive public education resource that emphasizes current events and announcements, as
well as providing tips and options for residents and businesses regarding:
•Waste reduction, reuse, recycling.
•Detailed facility (e.g., recycling and transfer facilities) information.
•Zero waste initiatives.
•Educational school-oriented resources.
•Event planning resources to increase recycling and reduce litter at special events.
Relating to social media, the SWD will occasionally post information to the Mayor’s Facebook page.
2019 Integrated Solid Waste Management Plan Update
County of Hawaiʻi
August 2020 5-3
Recycle Hawaii, a volunteer-based organization, provides information on recycling and reuse services via
its own website. Their site includes general recycling, waste reduction, and reuse information along with
specific County program information.
5.3.1.2 Radio, Television, and Print Media Advertising
The County advertises a variety of waste reduction and recycling programs, including Christmas tree
cycling, the polystyrene (Styrofoam) ban, green waste/mulch, 2-bin recycling, reuse centers, tire
recycling, household hazardous waste, e-waste, and used motor oil programs. Forms of outreach include
the Recycle Guide, signage, flyers, printed media advertisements, banners, radio spots, television
advertisements, and movie theater advertisements.
The County is expanding the program to further
educate the public about various waste issues and
keep them informed of upcoming events.
5.3.1.3 Flyers
The County and their vendors have prepared
flyers that cover a range of waste management
topics for public distribution. The flyers, which are
the same as the signage posted at the recycling
and transfer stations across the island, address
green waste recycling, composting, plastics
recycling, household hazardous waste, used
motor oil collection, and the HI-5 recycling
program. The flyers are available to the public at community events, at recycling and transfer stations,
and at other County solid waste facilities. They are also available in Portable Document Format (PDF) at
www.HawaiiZeroWaste.org. In early 2019, the County updated flyers related to the used motor oil
program; recyclable and non-recyclable materials; cardboard and paper bags; paper, metal cans, and
plastic; and glass.
5.3.1.4 Community Outreach
The County strives for transparency and collaboration in its ongoing efforts to further community
outreach. This includes an emphasis on networking with nonprofits, community groups, and businesses
whose goals align with waste diversion (waste reduction, recycling, and composting). There are clear
Recycling Education in Movie Theatres
2019 Integrated Solid Waste Management Plan Update
County of Hawaiʻi
5-4 August 2020
benefits of transparency and collaboration when and where possible and appropriate to build support
for a program, disseminate new information, and – perhaps most importantly – ensure that community
messaging is accurate and congruent. Examples of the County’s community outreach activities:
•Contracted with a consulting firm to assist with the design and coordination of an expanded
community outreach program. The expanded program emphasizes proper sorting and use of
recycling bins to reduce contamination in the waste stream.
•Developing a Master Recycler Program in collaboration with the nonprofits Recycle Hawaii and
Zero Waste Big Island. This program will include all aspects of waste diversion, not just recycling.
This will be modeled after existing programs, such as the Master Recycler Program in Oregon
(which has generously offered technical support).
•Developing a Facebook page as an additional opportunity for public connection. Again, this is
where networking with existing waste reduction and diversion-oriented groups will provide a
much broader audience with accurate and real-time information.
Transfer Station Thrift Store, LLC, (TSTS) the company that manages and operates the reuse centers at
select County recycling and transfer stations, are contractually obligated to provide community
education. TSTS provides educational brochures at all its locations, educating the public on landfill waste
and measures that can be implemented to further reduce waste.
5.3.1.5 Community Events
The County participates in various community
events throughout the year aimed at enhancing
environmental awareness (e.g., University of
Hawaiʻi, Hilo [UHH] Earth Day Fair). An emphasis
has been placed on the HI-5 program through the
installation of HI-5 recycle bins at larger
community events such as the Merrie Monarch
Hula festival. Organizations may reserve these bins
for their events, subject to availability.
As part of the County’s expanded community
outreach campaign, education material related to
waste reduction will be promoted at local sporting
and civic events. A County booth will be present at
these events to inform the public of their facilities
and of landfill diversion practices as well as providing current, up-to-date recycling information.
Promotional materials such as magnets, pens, pencils, and reusable bags—all bearing the
www.HawaiiZeroWaste.org address—are used to further spread the recycling message.
In addition, local nonprofit groups such as Hawai'i Wildlife Fund, Zero Waste Big Island, Recycle Hawaii,
Keep the Hawaiian Islands Beautiful, among others, participate in and/or create community events
throughout the year. For these events, recycling/reuse specialists are available to engage with the public
to answer questions and provide technical assistance.

5.3.1.6 School Programs
The County and its vendors organize a range of waste reduction and
recycling programs for local schools. The County currently offers
tours of the landfill, scrap metal and composting facilities, and the
recycling and reuse centers for school groups on an as-requested
basis. Complementary school programs offered by other
organizations are described below.
Recycle Hawaii provides school curriculum and presentations related
to zero waste, recycling, and sustainability. For example, Recycle
Hawaii encourages schools and organizations to “upcycle” materials
by reclaiming, recreating, or repurposing them through their Art and
Craft of Upcycling program. This program motivates participants to
practice sustainable practices by reducing and repurposing their
waste through a creative outlet. Submitted art pieces are showcased
on the Recycle Hawaiʻi website.
Keep America Beautiful’s Recycle-Bowl (Keep America Beautiful
2018) encourages schools to participate in a competition that tracks
the weight of their recyclables for 4 weeks. This program encourages schools to increase their recycling
rate and to educate students and teachers about waste reduction and sustainability.
The Ocean Conservancy’s International Coastal Cleanup Project encourages schools and volunteers to
participate in marine waste removal along shorelines. By identifying sources of debris and illustrating
the harmful impacts of debris on marine life, students and the public are inspired to properly dispose of
their waste.
5.3.1.7 Business Education
The County provides business education emphasizing proper disposal of commercial waste, the
polystyrene ban, and tire recycling. The County:
•Helps businesses dispose of commercial waste, such as mercury-containing light bulbs.
•Encourages the formulation of “Green Teams” where a business designates a group of
employees to manage and discuss opportunities related to waste reduction that could
ultimately result in cost-savings for the company.
•Provides the food service industry information and support during the transition Polystyrene
Foam Container & Food Service Ware Reduction program. A flyer is available to businesses
explaining how the food service industry can meet the County requirements.
•Maintains a tire recycling educational program that targets both the tire businesses and the
public. Activities have included inspection by a County contractor to see if businesses are
abiding with the state requirements, the provision of information on the state requirements,
and posters and radio and newspaper advertisements.
5.4 Issues and Concerns
As described above, the County currently invests resources into creative education and outreach
programs. However, given the County’s commitment to landfill diversion, additional effort could be
expended to further reduce the quantities of materials discarded in landfills. The County plans to
employ social marketing principles to guide the design and implementation of education programs.
County DEM: School Education
Program
2019 Integrated Solid Waste Management Plan Update
County of Hawaiʻi
5-6 August 2020
Social marketing is the planning and implementation of programs designed to bring about social change.
Some of its key concepts include the following:
•The ultimate objective of marketing is to influence action.
•Action is undertaken whenever target audiences believe that the benefits they receive will be
greater than the costs they incur.
•Programs to influence action will be more effective if they are based on an understanding of the
target audience’s own perceptions of the proposed exchange.
•Target audiences are seldom uniform in their perceptions and/or likely responses to marketing
efforts and therefore should be partitioned into segments.
Marketing efforts must incorporate all of the “4 Ps,” that is:
•Create an enticing “Product”—the package of benefits associated with the desired action.
•Minimize the “Price”—the target audience believes it must pay in the exchange.
•Make the exchange and its opportunities available in “Places” that reach the audience and fit its
lifestyles.
•“Promote” the exchange opportunity with creativity and through channels and tactics that
maximize desired responses.
Recommended behaviors always have competition that must be understood and addressed. Because
the marketplace is constantly changing, program results must be regularly monitored, and management
must be prepared to rapidly alter strategies and tactics to optimize the effectiveness of the program.
Other key features of successful education programs that the County would strive to achieve include the
following:
•Research different segments of the population who are targeted for programs.
•Maintain a consistent “look” for the program.
•Use a variety of communication methods.
•Keep detailed records of efforts and results.
•Evaluate the impact of education and promotion programs.
•Cross-promote solid waste management activities with other County environmental initiatives.
Relating to the contamination issue, new recycling signs have been developed and installed at the
recycling and transfer stations from early 2019 to middle 2019. The new recycling signs are consistent
with a standardized format, making it easier for visitors as well as residents to easily identify what and
how to recycle.
The County is considering requiring proper signage at businesses and public events. The County plans to
expand its technical assistance for businesses to educate and inform them of proper solid waste
management including waste reduction and recycling, as well as to encourage their customers of proper
recycling and composting practices. At community outreach and school events, brochures and fliers are
handed out to inform the public of proper recycling and waste diversion techniques.
5.5 Options for Improvement
Substantial progress in advancing the County’s landfill diversion objectives will require enhancements to
the County’s current education and outreach programs. Implementation of these programs and
initiatives will require additional funding for outreach activities. This could be achieved either directly by
the County or by contracts with appropriate consultants, vendors, or government entities.
2019 Integrated Solid Waste Management Plan Update
County of Hawaiʻi
August 2020 5-7
5.5.1 Develop 3-Year Landfill Diversion Education and Social
Marketing Plan
To maximize the effectiveness of the County’s educational and promotional efforts, a 3-year plan could
be developed that identifies the major goals and objectives of the County’s landfill diversion education
efforts, including specific programs and initiatives that will be implemented to obtain those goals. This
3-year plan would provide a schedule or “blueprint” of activities that will be undertaken to support
waste reduction and recycling activities. It would help ensure effective use of staff time and budget as
well as offering a benchmark for measuring success.
The 3-Year Landfill Diversion Education and Social Marketing Plan could:
•State the County’s key messages (broad goals and specific objectives).
•Identify specific demographic groups or geographical areas the County would like to reach with
its messaging. Identify educational programs tailored to target the specific types of materials
that are easy to recycle yet are not being diverted effectively, based on the results of the waste
stream assessment section of this Plan update.
•Develop improved public awareness programs that publicize current and future waste
management and recycling programs.
•Develop improved educational and promotional activities specifically geared toward new
programs and initiatives identified in this plan.
•Evaluate the benefit of providing educational and promotional materials in other languages.
•Identify how the County will measure the success of its efforts.
•Estimate the costs of future education and promotion efforts.
•Identify how to promote a change in administration and funding (e.g., PAYT program and fee
schedules for residents and businesses).
•Leverage cultural importance of proper waste management on Hawaiʻi Island–for its community
and for tourism.
The plan would address immediate, short- and long-term actions pertaining to the following programs:
•Diversion as an overarching County waste management policy.
•Residential waste reduction and reuse.
•School programs for waste reduction, recycling, and composting.
•Residential recycling.
•Visitor industry waste reduction and recycling.
•Business waste audit and education programs.
•Other business waste reduction and recycling.
•Construction and demolition waste reduction, reuse, and recycling.
•Implementation of alternative funding mechanisms.
Cost Considerations. To implement this option, the County would need to budget for consulting time to
assist in the preparation of an education and promotion plan and development of program identification
and materials.
2019 Integrated Solid Waste Management Plan Update
County of Hawaiʻi
5-8 August 2020
Recommendations from the plan would likely result in initiatives that would require funding in
subsequent years for plan implementation. The plan would be evaluated and updated every other year.
5.5.2 Conduct Waste Management Attitude Survey
The County would benefit from conducting a market survey to assess public attitudes about waste
management in the County. The survey would be used to assess perceptions, attitudes, and behavior of
non-users and users towards the County’s programs and services. The results could be used to shape
messages to target audiences in different communities.
The survey would be conducted over the telephone by a firm experienced in conducting market
research. Respondents would be randomly selected from commercially available lists that are specially
prepared and which provide telephone numbers in the target geographic area (excluding fax numbers,
business numbers, and other non-residential numbers).
Because non-response tends to increase with survey length, the survey would not exceed 10 minutes
because this tends to be the upper limit of tolerance for surveys. Methods such as using a predictive
auto dialer (PAD) and a computer-assisted telephone interviewing (CATI) system would be considered to
ensure randomness and survey efficiency.
Cost Considerations. To implement this option, the County would need to budget for consulting time to
conduct the market survey. It would also require County staff time to deliver, analyze, and monitor the
survey. The specific amount of spending for the survey would be developed as part of development of
the 3-year education and promotion plan.
5.5.3 Expand Existing Advertising and Marketing Efforts
The County currently advertises various aspects of its waste management program, such as recycling,
through television, movie theaters, radio, print advertising, and outreach at community or special
events. These efforts could be expanded to include zero waste programs and initiatives and incorporate
new themes or slogans implemented by the County. Expanded television and radio advertising could
include paid advertisements, as well as promotional opportunities such as news stories, talk show
interviews, and additional special event outreach.
Increasing the number and scope of County participation in community events is also recommended in
Chapter 4 Recycling, Bioconversion, and Markets. Expanding participation in community events will
create additional opportunities to distribute educational and marketing materials to both residents and
businesses.
Cost Considerations. This option could be funded at a variety of levels. The specific amount of spending
on added advertising and marketing would be developed as part of development of the 3-year
education and promotion plan.
5.5.4 Expand Public and Civic Outreach
The County plans to increase its presence at public outreach events. Events such as high school and
college sporting events as well as civic events such as fairs, festivals, and expositions. The County could
design a simple, easily transportable booth to further engage the public to learn about waste reduction,
proper waste disposal, and about the recycling and transfer stations. Literature and brochures would be
handed out to the public at these events as well as small promotional items such as magnets,
compostable pencils, and note pads with the www.HawaiiZeroWaste.org address.
2019 Integrated Solid Waste Management Plan Update
County of Hawaiʻi
August 2020 5-9
County presence at these events will spread the waste reduction and sustainability message to the
public. Not only will the community learn how and where they can properly dispose of their waste, they
can also discover how they are better able to reduce their ecological footprint through recycling and
reuse. Expanded outreach at more events will also increase accurate waste disposal on site.
Cost Considerations. Presence at public and civil events would require County staff time, preparation,
and analysis.
5.5.5 Expand School Education Programs
The County has a school outreach program that includes several educational initiatives being
implemented in the public schools around the island. These existing educational programs could be
expanded to incorporate a multi-level approach that is consistently implemented across a range of age
groups over time and would integrate zero waste concepts. Potential activities could include recycling
and composting initiatives, specific curriculum, field trips, guest speakers, and waste audits.
If the County incorporates recycling as a requirement for hauling contractors that service schools, as
recommended in Chapter 4, it could create opportunities for schools to involve students with the
recycling effort on individual campuses.
Cost Considerations. This option could be funded at a variety of levels. Much of the expense would be
for added staff time for County staff or contracts with its education vendors.
5.5.6 Expand Business Education Programs
The County plans to further encourage partnerships and sponsorships by local environmental and
community groups to help them take ownership of waste management concerns and provide
recognition for waste reduction successes. The County could expand on its program of technical
assistance for individual business owners and business and trade groups, with a focus on reducing both
the quantity of commercial and industrial discards to the landfill. The County could conduct technical
assistance that includes visiting the businesses, and suggesting ideas to further waste reduction
practices, and better inform them of business recognition opportunities. County education staff could
collaborate with other agencies that interact with businesses about environmental issues such as air,
energy, water, wastewater, and disaster planning to leverage resources and avoid duplication of effort.
Key steps in expanding the County’s business outreach programs could include the following:
•Identifying major generators and generating sectors.
•Developing a database of key contacts at individual businesses and organizations.
•Identifying classes of readily recyclable materials generated by businesses.
•Establishing priorities.
•Developing strategy and preparing education and outreach materials.
•Monitoring effectiveness.
•Revising and refining the program annually based on results of effectiveness analysis.
County education staff could also look to businesses that provide advertising services (such as utilities,
transit, newspapers) and search for opportunities for free advertising.
Cost Considerations. This option could be funded at a variety of levels. Much of the expense would be
for added staff time.
2019 Integrated Solid Waste Management Plan Update
County of Hawaiʻi
5-10 August 2020
5.5.7 Develop Visitor Industry Education Programs
Given the significant contribution of the visitor industry to the County’s waste stream, it would be
beneficial to develop focused educational and promotional programs that specifically target the visitor
industry. This could include developing brochures for hotels; adding more recycling bins at airports,
beaches, and parks; and installing displays at airports. The County could also provide a list of
recommended actions to hotels and resorts outlining measures they can implement to reduce waste,
and contact information for technical assistance. For example, a tip sheet for hotels and motels could be
formulated that illustrates best management practices in relation to waste reduction.
Cost Considerations. This option could be funded at a variety of levels. Much of the expense would be
for added staff time.
5.5.8 Evaluate Effectiveness and Continue to Refine Education Programs
The long-term success of the County’s education program will be dependent on the extent to which
educational and promotional materials can be continually modified to respond to changes in the
program. As part of this effort, the County would include ongoing evaluations of the progress and
effects of its source reduction and recycling programs. This effort would include evaluating the public’s
understanding of various programs, establishing benchmarks for success at current levels of effort, and
evaluating the effectiveness of education and promotional campaigns.
The information needed to evaluate the effects of an education and promotion program might be
gained through:
•Analysis of recycling rates, monthly participation rates, and capture rates.
•Analysis of levels of contamination in recycling programs.
•Analysis of the extent of media coverage.
•Personal interviews.
•Soliciting opinions at community events and meetings.
•Mail, telephone, or drop-off surveys.
•Focus groups.
•Mail-back response cards.
•Evaluation of the number of hits on the County’s website.
The County could include evaluation as part of every education and promotion program. Results would be
communicated to appropriate audiences including elected officials, interest groups, and the public.
Cost Considerations. A good rule of thumb is that approximately 10 percent of the cost of a program is
spent on the program’s evaluation to make changes as deemed necessary to ensure success.
5.6 Recommendations
Based on the analysis presented above and discussions with the SWAC, the Plan recommends the
actions listed below to improve public education and information program. . Many of the options
discussed above and other education initiatives, such as those in support of residential and business
2019 Integrated Solid Waste Management Plan Update
County of Hawaiʻi
August 2020 5-11
recycling, visitor industry waste management practices, and organics and composting, are addressed in
other sections of this Plan update.
1.Implement a 3-year education and social marketing program to educate the public and
business community about landfill diversion and recycling initiatives and opportunities,
including proper disposal and recycling to reduce contamination.
2.Conduct a waste management attitude residential survey.
3.Ensure the County has the staffing available commensurate with the needs of the public
outreach program.

6.HOUSEHOLD HAZARDOUS WASTE AND ELECTRONIC WASTE
6.1 Introduction
Household products exhibiting corrosive, reactive, toxic, or ignitable properties are considered “household
hazardous waste” (HHW), as defined by the EPA. These products include, but are not limited to:
automotive fluids, paints, oils, cleaners, pesticides, poisons, and batteries. They require special handling,
transport, and disposal or recycling methods, and they present special risks and disposal methods.
Electronic waste (e-waste) consists of any broken or unwanted electronic devices. Computers, VCRs,
copiers, stereo equipment, televisions, cell phones, and monitors are examples of common e-wastes.
Like HHW, many e-wastes, such as cathode ray tubes (CRTs) from older televisions and monitors, include
components that are toxic and restricted from the landfill. This chapter describes the status of the HHW
and e-waste collection and disposal system within the County, identifies current issues and concerns,
and presents options for achieving the County’s HHW and e-waste goals.
6.2 Regulatory Background
The discussion in this section describes the regulatory framework for management of HHW and e-waste.
6.2.1 Summary of Household Hazardous Waste Regulations
According to HRS 342G-1, solid or municipal waste is defined as:
Solid waste or municipal solid waste means: garbage, refuse, and other residential or
commercial discarded materials, including solid, liquid, semisolid, or contained gaseous
materials resulting from industrial, commercial, mining, and agricultural operations; sludge from
waste treatment plants and water supply treatment plants; and residues from air pollution
control facilities and community activities. This term does not include solid or dissolved materials
in domestic sewage or other substances in water sources, such as silt, dissolved or suspended
solids in industrial wastewater effluents, dissolved materials in irrigation return flows, or other
common water pollutants.
According to HRS 342J-2, hazardous waste means:
A solid waste, or combination of solid wastes, which because of its quantity, concentration, or
physical, chemical, or infectious characteristics may:
(1)Cause or significantly contribute to an increase in mortality or an increase in a serious
irreversible or incapacitating reversible illness; or
(2)Pose a substantial existing or potential hazard to human health or the environment when
improperly treated, stored, transported, disposed of, or otherwise managed.
HHW are typically generated in small quantities and, as a result, are not considered hazardous waste.
HHW are exempt from federal and state hazardous waste regulations, according to the Code of Federal
Regulations (CFR) 40 Part 261.4 and the State of Hawaiʻi Administrative Rules (HAR 11-261-4). According
to HRS 342G-1 definitions, household hazardous waste means:
Those wastes resulting from products purchased by the general public for household use which,
because of their quantity, concentration, or physical, chemical, or infectious characteristics, may
pose a substantial known or potential hazard to human health or the environment when
improperly treated, disposed of, or otherwise managed.
2019 Integrated Solid Waste Management Plan Update
County of Hawaiʻi
6-2 August 2020
Because components of household waste may be hazardous to human health or the environment,
HRS 342G-26 requires that integrated solid waste management plans:
1.Assess the quantity and type of hazardous wastes generated by residences in the county;
2.Describe current collection, recycling, and exchange programs, as well as current methods of
disposing of household hazardous waste; and
3.Develop programs for the collection of household hazardous wastes that protect the public and
the environment from these substances. The household hazardous wastes collected by the
counties shall be disposed of by a state program.
6.2.2 Summary of E-Waste Regulations
As of 2010, the Hawaiʻi legislature enacted Act 13 to encourage recycling of electronics, and mandated
manufacturers to establish, conduct, and manage take-back recycling programs for “covered electronic
devices” (CEDs). Act 13 was revised in 2011 to include “covered televisions” (CTVs). The HDOH is
responsible for implementing the “Hawaiʻi Electronic Device Recycling Program.” Manufacturers of CEDs
sold in Hawaiʻi must register with HDOH and pay an annual registration fee of $5,000 and must set up
recycling plans. Television manufacturers must follow the same protocol except for the fee, which is
$2,500 annually. Any manufacturer that sells both CEDs and CTVs are required to pay a combined
$7,500 in annual registration fees. The collected fees are used by HDOH to administer the program.
According to Chapter 339D, Electronic Waste and Television Recycling and Recovery Act, a “covered
electronic device” or “covered television” includes a computer, computer printer, computer monitor, or
portable computer with a screen size greater than 4 inches measured diagonally; and televisions with a
viewing screen greater than 9 inches intended for use by a household. The program does not cover
certain electronic devices including those that are a component of a motor vehicle, part of a larger part
of equipment (e.g., medical diagnostic equipment), or electronic devices in appliances (e.g.,
refrigerator), nor does it include telephones or global positioning system (GPS) units. The program is
offered to any household, government entity, business, or nonprofit organization exempt from taxation
under Section 501(c)(3) of the United States Internal Revenue Code, regardless of size or place of
operation within the State.
6.2.3 Review of 2009 Plan
Exhibit 6-1 provides a summary of the recommendations from the 2009 Plan relative to household
hazardous waste and e-waste, and describes the actions taken to achieve each recommendation.

6.3 Existing Conditions
Household hazardous waste in the County is collected on specified collection dates at select recycling and
transfer stations during the year. E-waste is collected every Saturday on a rotating schedule at the Wai‘ōhinu,
Waimea, Kealakehe, and in Hilo at Mr. K's Recycle & Redemption Center.
The County provides public awareness and educates residents on HHW and e-waste programs,
promotes HHW collection events, and contracts for the collection of the hazardous products, which are
then shipped to the mainland for proper disposal or treatment. The following subsections describe in
greater detail the County’s existing e-waste and HHW program.
2019 Integrated Solid Waste Management Plan Update
County of Hawaiʻi
6-4 August 2020
6.3.1 Household Hazardous Waste
An established HHW collection frequency of six HHW collection events per year are held at four of the
recycling and transfer stations.
Success at the Hilo and Kealakehe (Kailua-Kona) recycling and transfer stations caused unacceptable
traffic congestion during the HHW collection events. Both sites were relocated to accommodate traffic
flow. The Hilo and Kealakehe (Kailua-Kona) recycling and transfer stations each historically hosted two
HHW collection events per year. The County's FY 2020–21 budget reduced the frequency to one event
per year in August in Hilo and Kealakehe (Kailua-Kona), instead of two. Eventually, the County plans to
resume twice a year collection.
Future HHW collection events are currently scheduled for the following specific dates at these four locations:
•Hilo: Waiākea High School—First Saturday of August, 7:30 a.m. to 2:30 p.m.
•Kailua-Kona: Kealakehe High School —Second Saturday of August, 7:30 a.m. to 2:30 p.m.
•Pāhoa Recycling and Transfer Station—First Sunday of March, 8:30 a.m. to 3:30 p.m.
•Waimea Recycling and Transfer Station—First Saturday of March, 8:30 a.m. to 3:30 p.m.
HHW collection rates have remained consistent the past 5 years with a marked decrease from years
prior (FY 2010 to FY 2012 averaged 136 tons/year while FY 2013 to FY 2017 averaged 58 tons/year). This
difference is attributable to residents having greater opportunities for battery disposal at other non-
County-managed locations as well as the promotion of Do-It-Yourself Used Motor Oil Collection sites
available year-round to residents. Exhibit 6-2 displays the type and quantities of HHW collected from FY
2015 through FY 2017.

a After 2013, the County stopped accepting automotive batteries at the recycling and transfer stations due to high disposal costs. However,
these batteries are accepted at County-run take-back days where residents may bring in their household hazardous waste free of charge.

The HHW program is free for County residents. It is advertised via signage and flyers at the recycling and
transfer stations, newspaper and radio advertisements, and on the County HawaiiZeroWaste.org
website. Social media outlets also promote the events such as local community Facebook pages, and
nonprofits (e.g., Recycle Hawaii). Video feeds such as Big Island Video News promote the events at no
cost to the County.
Commercial entities may contact private contractors for hazardous waste storage, recycling, and/or
disposal. Residents who cannot come to one of the events or who have items that are not acceptable for
collection at the residential events, can contact private contractors to have their HHW disposed for a fee.
6.3.2 E-Waste
The “Computers, Electronics, & Printer Cartridges” page of the County’s HawaiiZeroWaste.org website
explains why e-waste should be recycled and provides resources for the public to learn more about the
State of Hawaiʻi Electronic Device Recycling Program. The website lists the locations where items can be
recycled free for residents and for a fee for both businesses and residents. The website also provides an
inventory of manufacturers and producers that have their own trade-in recycling programs where it is
possible that a consumer may get value for the e-waste item towards the purchase of new electronic
equipment (or in some cases, may get a return in value without making a purchase [e.g., mobile
telephones and accessories]).
The County also recycles more types of e-waste than what is supported by the Electronic Waste and
Television Recycling and Recovery Act. The County also recycles VCRs, CD/DVD players, stereo
receivers/amplifiers (no speakers), UPS systems, digital cameras, and mobile and landline telephones—
none of these items are listed as approved Covered Electronic Devices (CEDs) under the Hawaiʻi
Electronic Device Recycling Program (see Section 6.2.2).
E-waste is accepted at one permanent drop-off site in Hilo, Mr. K’s Recycle and Redemption (Mr. K’s),
which is open daily from 8:30 a.m. to 4:30 p.m. Residents can recycle their e-waste for free on Saturdays
and must pay a fee of $0.55 per pound on the other days. E-waste accepted includes televisions,
computers, laptops, monitors, printers/fax machines/multi-function printers, VCRs, CD/DVD players,
stereo receivers/amplifiers (no speakers), UPS systems, digital cameras, and mobile and landline
telephones. Microwaves and heating/cooling devices are not accepted. Commercial entities may also
recycle e-waste at Mr. K’s; however, businesses are normally charged a fee of $0.95 per pound to recycle
e-waste Sundays through Fridays, with a discounted rate of $0.55 per pound on Saturdays. In June 2018,
Mr. K’s held a one-day special event allowing free e-waste collection for everyone, including nonprofits,
state/government agencies, and businesses by appointment only. Approximately 73,624 pounds of
commercial and 7,932 pounds of County government e-waste were collected during this event.
In addition to free e-waste recycling every Saturday at Mr. K’s in Hilo, free residential household e-waste
recycling collection occurs on other parts of the island on a monthly rotating basis at three locations:
•Wai‘ōhinu Recycling and Transfer Station—First Saturday of every month.
•Waimea Recycling and Transfer Station—Second Saturday of every month.
•Kealakehe (Kailua-Kona) Recycling and Transfer Station—Third Saturday of every month.
These collections are prohibited from accepting e-waste from businesses, agencies, and nonprofits.
Rotating e-waste collection sites are open from 9 a.m. to 4 p.m., only on their scheduled days. The list of
e-waste accepted at the County facilities, also collected at Mr. K’s Recycle and Redemption, are
described above. In addition to managing the permanent e-waste collection site in Hilo, Mr. K’s Recycle
and Redemption collects e-waste from the rotating drop-off sites, then repairs a small portion for resale
and/or recycles the material. Other local companies provide e-waste recycling services for a fee.

Many manufacturers and producers of electronics have programs that allow consumers to get value for
their products through trade-ins or to simply recycle their e-waste. The County’s website lists the
retailers and manufacturers with website links to these recycle/trade-in programs (e.g., Walmart,
Panasonic, Nokia). The County website also provides contract information for businesses that take-back
mobile telephones and accessories (e.g., Sprint, AT&T) and inkjet/toner cartridges (e.g., Office Depot,
Target). Local retailers who collect e-waste ship the e-waste to the mainland for recycling at certified
facilities. The mainland recyclers segregate the e-waste into glass, plastics, and metals components,
which are sold to waste management entities. Exhibit 6-3 presents the total quantity of e-waste
collected during the 2010 to 2018 fiscal years.

As described in Chapter 3, there are
seven reuse centers throughout the
County sited next to the recycling and
transfer stations. Though not
classified as e-waste, these centers
allow residents to drop off unwanted
and still useful small electronic
appliances that still have some use
left in them. Residents can then
purchase the appliances for a nominal
fee at the center.
In 2006, 2008, and 2010; the
University of Hawaiʻi (UH), in
conjunction with Apple Corporation,
sponsored the Hawaiʻi Education and
Government eDisposal Day. The
event allowed residents to dispose of their personal e-waste during a single-day event at locations in
Hilo and Kona and two events in Maui (Kahului and Līhue). In 2012, the event was expanded to allow
3 days of e-waste collection from County, state, or federal military branches; small to medium-sized
businesses (of less than 100 employees); and nonprofit organizations while continuing with single-day
event for Hawaiʻi households. It is estimated that over 5 million pounds of e-waste was collected
statewide during these events. The UH is no longer holding these community events; however, they are

still recycling university-generated e-waste on a quarterly basis and encouraging reuse through a
university-supported “swap meet.” The Apple Corporation is still supporting their efforts.
6.4 Issues and Concerns
6.4.1 Household Hazardous Waste
Household hazardous waste presents unique hazards to humans and the environment. Storage,
handling, transport, and disposal of hazardous waste require special procedures and equipment.
Currently, there are a limited number of locations for residents and businesses to dispose of HHW. The
distance to collection sites, and challenges associated with storage, handling, and transporting HHW
may be a disincentive for residents or businesses in rural areas to properly dispose of their waste.
If transfer or landfill staff identify HHW, they take steps to manage it appropriately and keep it out of
the landfill. County staff also respond to occasional reports of HHW discarded in remote areas of the
County. However, once in a garbage bag or bin, it is very difficult (and expensive) to identify HHW in the
waste stream.
Despite the County’s current efforts to keep HHW out of its landfills, the 2008 County of Hawaiʻi Waste
Composition Study estimated that 527 tons of HHW was disposed of in County landfills in FY 2008.
Although the County added two new collection locations for hazardous waste in 2008, the amount of
hazardous waste collected has decreased. For example, FY 2010 through FY 2012, HHW collected was
approximately 243 tons, and for FY 2015 through FY 2017, approximately 191 tons 6. With an average of
only 87 tons/year of hazardous waste managed between FY 2010 and FY 2017, and the estimated 527
tons disposed of in County landfills in FY 2008, there is a marked need to increase funding to educate
the public about this program. [The County spent about $220,096 on its HHW program in FY 2017, of
which approximately $11,000 was used towards advertising the program]. Thus, additional education
and more convenient opportunities to properly manage HHW would be beneficial. Potential
opportunities for improving the existing system are presented below.
6.4.2 Electronic Waste (E-Waste)
The County is charged $0.55 per pound by the vendor to collect, process, and market the e-waste. The
County pays for the residential e-waste program through state funding (electronic device recycling
fund 7) and property taxes; however, there is no similar program to address e-waste generated by
businesses, schools, or government entities such as the military branches. Although the County provides
businesses with a reduced rate on Saturdays, the cost of e-waste disposal remains a disincentive for
many private businesses to recycle e-waste, and results in much of the business e-waste being sent to
the landfills. A lack of staff assigned to monitoring and enforcement at recycling and transfer stations
and landfills contributes to e-waste entering the landfills.
6 In FY 2009 through FY 2011, a large component of HHW was car batteries; they were not collected under the
HHW program in later years. The car battery tonnage was removed for a more accurate comparison to later years
of collection.
7 According to Chapter 339D, Electronic Waste and Television Recycling and Recovery Act, there is an electronic
device recycling fund, which is a culmination of fees, payments, and penalties as collected from manufacturers and
retailers. The funds are administered through the HDOH, and expended for the sole purpose of implementing and
enforcing the Electronic Waste and Television Recycling and Recovery Act.
2019 Integrated Solid Waste Management Plan Update
County of Hawaiʻi
6-8 August 2020
The State of Hawaiʻi’s Electronic Waste and Television Recycling and Recovery Program is a positive step
in reducing e-waste disposal although e-waste is not banned from landfills under state or Hawai’i County
laws. The City and County of Honolulu have a landfill ban on business and governmental e-waste, while
households are exempt. Stronger legislation may be required to deter residents or businesses from
disposing of e-waste in ways that result in the waste entering landfills. The HDOH 2016 Report to the
legislature underlines several concerns and challenges related to the Electronic Waste and Television
Recycling and Recovery Program:
1.The law gives manufacturers too much leeway in recycling programs they offer consumers. With
no criteria or performance standards tied to the manufactured-generated recycling plans (which
describe collection and recycling procedures), some manufacturers end up implementing
inconvenient programs that require consumers to do much of the work to recycle their Covered
Electronic Devices (CEDs).
2.Most collection programs have been drastically scaled back, or eliminated because of budget
constraints, and comprehensive services are centered on O`ahu because of its population
concentration.
3.Some manufacturers do not put effort in establishing CED recycling programs (as evidenced by
the reporting of recycling 0 pounds of CEDs) and other manufacturers are only implementing
programs in Oahu, with no comprehensive services to the other islands.
The 2016 Report to the legislature suggests that statutory mandates for minimum e-waste recycling
goals and customer convenience are necessary to encourage a state-wide program that is both effective
and convenient. The HDOH’s plan is to continue to work with the Legislature to strengthen the program
with respect to consistency of service provided across the state, convenience of the recycling programs,
long term stability of the programs, and to setting recycling goals. The ultimate final disposition of e-
waste is an important factor to consider with e-waste recycling or disposal. Disposal or recycling of e-
waste by uncertified companies can potentially result in discarded e-waste being shipped to third world
countries where fewer desirable practices are implemented. Use of certified recyclers can increase costs
of recycling or disposal. The County’s current program (implemented through Mr. K’s Recycle and
Redemption) uses recyclers that provide certificates of destruction. The County spent about $165,000
($0.55 per pound) on its e-waste recycling program in FY 2017–18. State grants are available to help
defray the cost of recycling, the County received a $160,000 grant from the state for FY 2018–19 and will
receive the same amount in FY 2019–20.
The design of collection facilities for e-waste and HHW must consider special conditions within the
County, including invasive species concerns, and operating conditions in areas where the facilities are
established. Dangerous conditions (wet and slippery surfaces in high precipitation areas) and the
potential for export of invasive species (such as African tree snails or coqui frogs) must be evaluated
during design.
6.5 Options
An overview of various options that could be implemented to improve the management of HHW and e-
waste follows. These options were developed based on successful initiatives implemented in other
jurisdictions that may be applicable and appropriate for the County.
2019 Integrated Solid Waste Management Plan Update
County of Hawaiʻi
August 2020 6-9
6.5.1 Install Permanent Collection Facilities at Recycling and
Transfer Stations
Permanent collection facilities at recycling and transfer stations would provide more opportunity for
residents to properly dispose of HHW, e-waste, and some special wastes. The facilities could be
incorporated into the standard layout design at selected stations. The County has constructed a special
waste collection facility at the Pāhoa Recycling and Transfer Station as a component of its upgrade;
however, it is currently unused due to staffing deficiencies. Guidelines could be developed for both
residential and business use of the facilities.
Facilities are designed with safe work practices in mind for operation of equipment such as forklifts or
trailers. Operational plans are established to minimize the risk of injury to workers. In areas with higher
rainfall, facility designs include covered or enclosed areas that incorporate measures to prevent invasive
species from entering waste storage areas or being transported off site with waste.
Having fixed facilities at recycling and transfer stations would potentially reduce the amount of illegal
dumping, and would allow the County to set up a safer and more efficient system for storage, handling,
transport, and eventual disposal of the wastes.
Cost Considerations. Permanent facilities for HHW can range significantly in costs depending upon their
design and function. If permanent facilities are developed at multiple recycling and transfer stations, the
facilities could be smaller and would be less costly. Annual operating costs would depend on how often
the facilities are open and the extent to which the programs are successful in attracting HHW.
6.5.2 Implement Additional Collection Events
Additional one-day collection events, combined with promotional campaigns, could potentially increase
diversion of HHW, e-waste, and special waste from the landfills. Events could be designed to target a
single type or multiple types of waste. Similar to the currently scheduled events, the County could
sponsor events that are implemented on an island-wide basis, or community-specific events that are
rotated through various geographic areas. The County could conduct such events at fixed locations, or
conduct a mobile event utilizing trucks or trailers set up to transport specific types of waste. The County
could also set up events that are specific to either residents, agricultural businesses, or commercial and
industrial businesses.
For e-waste only, collection events could be accomplished using a trailer or container that would rotate
among various recycling and transfer stations. A schedule could be published that documents the days
that the service would be provided by location. As an example, a trailer could get to 12 locations each
year if it spent a set week every third month at a different station (that is, second week of January, April,
and July).
Cost Considerations. Costs for conducting such events would include cost of temporary facilities to store
wastes dropped off during the events, costs for promoting the events, and additional training costs for
staff who would manage the events and the storage and handling of the waste. Additional expenses
would include the cost of any subcontracted waste hauling or disposal firms used to transport and
dispose of the waste collected.

County of Hawaiʻi
6-10 August 2020
6.5.3 Establish E-Waste Take-Back Programs with Manufacturers
or Sellers
As described in Section 6.3.2, the Computers, Electronics, & Printer Cartridges page of the SWD’s
website (HawaiiZeroWaste.org) does a thorough job explaining why e-waste should be recycled, and
provides resources for the public to learn more about the Hawaiʻi Electronic Device Recycling Program,
which includes an inventory of manufacturers and producers that have their own trade-in recycling
programs. The County’s website lists the retailers and manufacturers with website links to these
recycle/trade-in programs (e.g., Walmart, Panasonic, Nokia). The County website also provides contract
information for businesses that take back mobile telephones and accessories (e.g., Sprint, AT&T) and
inkjet/toner cartridges (e.g., Office Depot, Target). There are also opportunities for corporate
sponsorships (e.g., UH program with Apple Corporation, Hawaiʻi Education and Government eDisposal
Day) to promote e-cycling.
The County could potentially apply for grants from manufacturers, or work directly with sellers to
establish collection events to promote the concept of producer take-back programs and the general
importance of e-cycling.
Cost Considerations. The County already incorporates information about e-waste take-back programs
into their educational materials on their HawaiiZeroWaste.org website. They could expand this program
by working in conjunction with either sellers or manufacturers to establish take-back programs that
involve collection events (similar to the UH/Apple Corporation-sponsored Hawaiʻi Education and
Government eDisposal Day). It would require additional costs for the County to provide staff to initiate
and manage such programs. Some costs could potentially be offset by grants provided by the
manufacturers or sellers.
6.5.4 Implement Advanced Disposal Fee for E-Waste
The County could implement requirements to collect advance disposal fees on certain types of e-waste.
The fee would be collected at the point of sale and would be earmarked to support the management
and eventual disposal when the e-waste reaches the end of its useful life. Currently, only California has
implemented legislation requiring consumers to pay a fee upon purchase of equipment. The California
law applies to purchases of specific types of e-waste items known to contain materials that are
considered hazardous upon disposal (primarily televisions, computers, and other types of equipment
that use CRTs, liquid crystal displays, or plasma screens). The fee only applies when purchasing new
equipment and is restricted to products covered under the law. Retailers are required to implement the
fee system and can capture 3 percent of the fee to cover the costs of implementing the program.
Cost Considerations. Implementation of this type of system would require the County to invest labor
costs to draft legislation supporting the requirements, and to implement a program to manage money
collected. It is anticipated that implementation of such a program could potentially result in revenue
that would partially offset costs the County would eventually spend to manage disposal of e-waste
generated at recycling and transfer stations or during collection events. Costs would be incurred by local
retailers and manufacturers to establish and administer the program. Consumers would ultimately pay
any added cost associated with the fee at the point of purchase.

County of Hawaiʻi
August 2020 6-11
6.5.5 Explore Public-Private Partnership for Local E-waste Campaign
(anything with a plug)
The 2009 Zero Waste Implementation Plan discussed the concept of hand-dismantling electronic
components (e-waste) to segregate high-grade metals and segregate working parts rather than shipping
materials off island as is currently the practice under the Electronic Waste and Television Recycling and
Recovery Act. Currently, e-waste collected on the island is shipped, typically without being pre-sorted, to
the mainland for proper disposal. An on-island e-waste campaign would present a potential opportunity
to create value-added products, jobs, and tax revenues in the County rather than shipping e-waste off
island to benefit another jurisdiction.
There are several ways to initiate on-island hand-dismantling of e-waste:
•Provide financial incentives for local dismantling to a company that is currently shipping bulk e-
waste off the island.
•Encourage a joint venture with companies that have established hand-dismantling operations,
or have designed their own e-waste processing equipment and may be seeking joint ventures
with nonprofit organizations or for-profit businesses.
•Apply for a grant to promote green infrastructure jobs.
In this option, the County would study different models for promoting local dismantling of e-waste and
convene a meeting of interested parties to determine the level of interest and what help might be
needed to move forward. The County could assist them in implementing a process on their own (perhaps
with some initial funding support) or issue a request for proposals to develop new services as needed.
Depending on the material source and process used for dismantling, a solid waste and/or hazardous
waste permit may be required.
Cost Considerations. The cost of an e-waste campaign could vary widely depending on the extent to
which the program would require County funding to initiate and sustain. The funding would have to
cover an initial study to investigate opportunities.
6.6 Recommendations
Based on the analyses presented above, and the preferences of the SWAC and County staff, the Plan
recommends the actions listed below to improve the HHW and e-waste program. Proposed funding and
the timing of implementation for each program are described in Chapter 10.
1.Ensure enough staffing to operate HHW/e-waste programs successfully. The current County
staffing level is a limiting factor for the implementation of new waste management programs.
Whether new programs are implemented solely by County staff or involve subcontractors,
additional staff will be necessary to successfully initiate and manage new programs. To expand
the HHW and e-waste programs, it is recommended that the County review the staffing needs
to make the program successful.
2.Implement HHW/e-waste public education, outreach, and public awareness program. As a
component of the additional HHW and e-waste programs, advertising will need to be increased
to make the public aware of the events and to encourage participation. The County would
expand the existing marketing programs through:
Providing event-specific announcements or advertisements.
Displaying additional signage at recycling and transfer stations.
2019 Integrated Solid Waste Management Plan Update
County of Hawaiʻi
6-12 August 2020
Expanding outreach programs by conducting community-based educational events at
schools or other public institutions.
3.Research and evaluate elements of successful e-waste/HHW programs implemented in other
jurisdictions and integrate those successes into the County’s program.
4.Explore e-waste take back programs with state and manufacturers/sellers. Take-back
programs by manufacturers and sellers of e-waste are a cost-effective method to divert e-waste
from landfills. Such programs can reduce costs of proper disposal for consumers, make it more
convenient for consumers to discard their e-waste, and ultimately, provide an incentive for
manufacturers to design less toxic and more recyclable products. It is recommended that
County staff:
Conduct research to assess what legislation may be required to mandate and manage take-
back programs for specific types of e-waste.
Coordinate with other counties and the state to develop and implement e-waste take-back
EPR programs.
Coordinate with local retailers to facilitate implementation of take-back programs for e-
waste.
Assess legislative actions that may be necessary to improve e-waste programs including
demanufacturing, storage and handling, and funding equity.
5.Conduct additional HHW collection events. During the development of the 2009 Plan update, a
consensus was expressed by the SWAC that periodic HHW collection events were successful and
offered the best opportunity for both proper disposal of HHW and diversion of these wastes
from landfills. One of the most prevalent comments was that the number and locations of
collection events be expanded to create additional opportunities for proper HHW disposal. It is
recommended that the County establish 10 to 12 additional HHW collection events per year.
6.Explore legislative actions for hazardous products and packaging take-back programs. Take-
back programs by manufacturers and sellers of hazardous products are a cost-effective method
to divert these types of waste from landfills. It is recommended that County staff:
Conduct research to assess what legislation may be required to mandate and manage take-
back programs for specific types of hazardous waste or packaging.
Assess what legislative actions may be necessary to facilitate storage and handling of
hazardous products and packaging at various types of collection locations, and funding
equity.
7.Explore public-private partnership for a local e-waste campaign (on-island demanufacturing). It
is recommended that the County initiate a study of different models for promoting local
dismantling and refurbishing of electronics. As part of the study, the County would convene a
meeting of interested parties to determine the level of interest and identify ways that the County
can help facilitate development of a locally-based e-waste program. Depending on the economics
of on-island dismantling, the County could then evaluate the extent to which it would provide
funding to support implementation of a public-private partnership e-waste program.

7.SPECIAL WASTE
7.1 Introduction
As defined in Hawaiʻi Administrative Rules 11-58.01-03, “Special wastes” means any solid waste which,
because of its source or physical, chemical, or biological characteristics, require special consideration for
its proper processing and/or disposal. This term includes, but is not limited to, asbestos, used oil, lead
acid batteries, municipal waste combustion ash, sewage sludge that is non-hazardous, medical wastes,
tires, white goods, and derelict vehicles.
Special wastes typically comprise a significant portion of the total waste stream for most communities.
The South Hilo Sanitary Landfill (SHSL) formerly accepted a wide range of special wastes; however,
because the site closed in 2019, the West Hawaiʻi Sanitary Landfill (WHSL) receives the bulk volume of
special wastes in the County.
7.1.1 Review of 2009 Plan Update
Exhibit 7-1 is a summary of the recommendations put forth in the 2009 Plan update relative to source
reduction, and a description of the actions taken to achieve each recommendation.
Exhibit 7-1. Status Update of 2009 Plan Recommendations for Special Waste
2009 Plan Update Recommendation Status
Include special waste drop-off and collection areas in the design of
new or renovated recycling and transfer stations.
Limited special wastes drop-off
opportunities designed/implemented
(White Goods).
Continue the current effort to modify convenience center permits to
allow white goods recovery at recycling and transfer stations.
Modified certain permits for White
Goods acceptance.
Include information regarding the environmental benefits of
properly disposing of scrap tires, and current disposal options in the
County's education and promotion programs.
HDOH administers the tire/wholesaler
scrap tire education program. The
County implemented an educational
program that targeted both the tire
dealers and the public. The County also
did multiple inspections of each tire
dealer and provided information to the
dealer on proper tire management.
7.2 Background
Special wastes are generated by both residents and commercial businesses, and in some cases require
special handling or processing to comply with federal and state regulations. As shown in Exhibit 7-2,
certain types of special wastes can be disposed of in WHSL, with varying levels of documentation
depending on the type of waste. Some types of special wastes cannot be disposed at the landfill and
require transport to separate recycling, processing, or disposal facilities. The County manages many
types of special wastes by establishing drop-off or collection points, and then transporting the waste
materials to either the landfill or other recycling or disposal facilities.
The County Department of Environmental Management (DEM) sponsors household annual and bi-
annual hazardous waste collection events at select recycling and transfer stations for residential waste.
2019 Integrated Solid Waste Management Plan Update
County of Hawaiʻi
7-2 August 2020
Special wastes accepted at these events include used oil (also accepted at six permanent collection
locations), lead-acid batteries, and medication. Waste must be from residential households. Commercial
and industrial-generated wastes are managed through the Hawaiʻi Department of Health (HDOH).

7.2.1 Asbestos
Asbestos-containing materials (ACM) are currently accepted for disposal at the WHSL in designated
areas within the landfill.
7.2.2 Used Motor Oil
The County sponsors a do-it-yourself used oil recycling program. The program is funded by the County,
made possible through the donated support of businesses collecting the used motor oil. Under the
program, residents can drop off used motor oil at no charge at any of seven collection locations. The oil
is accumulated at these collection centers, and then transported to recycling or energy recovery
facilities by waste hauling or disposal contractors. During 2015, 2,750 gallons (86.6 tons) of motor oil
were collected and either recycled or used in an energy recovery facility (County of Hawaiʻi DEM 2016a).
During the period from January through June 2016, 2,035 gallons (64.1 tons) of used motor oil were
collected (County of Hawaiʻi DEM 2017b).
Potential issues (public health and environmental) with used motor oil disposal include residents
disposing of used motor oil into the waste stream that enters the landfills, discarding containers of used
oil at the recycling and transfer stations, or discharging used oil to the ground surface.
7.2.3 Petroleum-Contaminated Soil
Soil affected by release of petroleum products is currently accepted at the WHSL, if it has been
chemically profiled and determined to be non-hazardous. The contractor, Waste Management
Corporation, reviews chemical profiling data for petroleum-contaminated soil entering the WHSL, and
manages the placement and disposal of this material at the landfill.
2019 Integrated Solid Waste Management Plan Update
County of Hawaiʻi
August 2020 7-3
7.2.4 Used Batteries (lead-acid)
Used lead-acid batteries are typically recycled by distributors such as auto parts stores or auto service
centers. Prior to 2013, specific collection areas for batteries were set up at the Kealakehe, Hilo, and
Kea`au recycling and transfer stations. They were transported to their respective base yards and
eventually to scrap metal yards or handled as household hazardous waste (HHW). After 2013, the
County stopped accepting automotive batteries at the recycling and transfer stations. However, these
batteries are accepted at County-run HHW collection events where residents may bring in their HHW
free of charge.
Potential issues with used battery disposal include residents disposing of batteries into the waste stream that
enters the landfills, discarding used batteries at recycling and transfer stations, or in more remote areas.
7.2.5 Sewage Sludge
WHSL receives non-hazardous sewage sludge from the Hilo Wastewater Treatment Plant, and from two
private wastewater treatment plants. Other private facilities, including resorts and a private wastewater
treatment plant located in Waimea, recycle sewage sludge by composting the sludge on their
properties.
7.2.6 Agricultural and Farm-Generated Waste
Agricultural wastes generated in the County typically include dead livestock, spoiled foods, and green
waste. Farm-generated wastes include containers of herbicides, pesticides, or other agricultural
chemicals. Currently, the County accepts livestock, or makes arrangements to assist the owner with
proper burial of deceased large animals (smaller animals such as cats and dogs are accepted at the
landfill). Green waste produced at farms is most frequently used by the farm owners. Green waste is
accepted for recycling at EHOF and WHOF; residential green waste is accepted at select recycling and
transfer stations, as described in Chapter 4 Recycling, Bioconversion, and Markets.
The HDOH’s pollution coordinator provides guidance for the management and disposal of farm-
generated hazardous wastes. Relating to pesticides, conditionally exempt small quantity generators
(CESQGs) may contact the state’s pesticide branch for disposal information. Triple-rinsed chemical
containers are allowed in the commercial solid waste stream (HDOH 2013).
7.2.7 Medical Wastes
Under Hawaiʻi County Code, untreated medical wastes are considered “prohibited materials” and not
allowed to be disposed in landfills. Medical wastes pre-treated at the generating facility to remove
pathogens and other hazards are permitted to be disposed at the WHSL.
To prevent misuse and improper disposal of prescription drugs and sharps, various levels of government
have developed pharmaceutical take-back programs:
•The U.S. Drug Enforcement Administration (DEA) offers bi-annual free take-back days for
prescription and Over-The-Counter (OTC) pharmaceuticals.
•The State of Hawaiʻi Department of the Attorney General, HDOH, and the Hawaiʻi County Police
Department (HCPD) administer the Hawaiʻi Medication Drop Box Program through federal
funds. Residents may dispose of their prescriptions in designated boxes located inside the Hilo,
Puna, or Kona police stations.
2019 Integrated Solid Waste Management Plan Update
County of Hawaiʻi
7-4 August 2020
•The County accepts residential prescription drugs at Kona or Hilo’s HHW collection events, or at
Waimea or Pāhoa’s annual HHW collection event.
•Longs Drugs operates a take back program for prescription medications, over-the-counter
medications, and liquid medicine bottles Hilo, Pāhoa’s, and Kona (Kealakehe). This was made
possible through the House Bill (HB)-1272 that was passed by the state legislature in 2019.
Sharps and needles are not accepted at these events. Residents may dispose of their sharps and needles
through their medical provider or by properly securing their syringes in a puncture-resistant container
and placing it in the garbage. Information on proper disposal of needles and pharmaceuticals are
provided on the County’s zero waste website.
Some businesses subcontract medical waste disposal to private businesses that specialize in medical
waste disposal. The HDOH is the lead regulatory agency tasked with oversight per HAR 11-104.1. In FY
2016–17, an estimated 442 tons of treated medical waste were disposed of at County landfills.
While medical waste management practices are generally effective, County staff members have, on
infrequent occasions, observed untreated medical waste at recycling and transfer stations or landfills.
7.2.8 Used Tires
County Ordinance No. 07-182, as codified in HCC 20-46, prohibits the disposal of tires that are whole,
cut, sliced, chipped or shredded at any landfill and all island-wide transfer stations. The County does
not collect tires at recycling and transfer stations or landfills, and it is illegal for residents and business
owners to drop off tires at any County facility. Both residential and commercial scrap tires are typically
collected and disposed of by automotive service centers during installation of newly purchased tires.
Residents can also drop off tires at several local companies that are permitted by the HDOH to conduct
tire disposal facilities; these businesses charge a nominal fee to dispose of used tires. Scrap tires on
abandoned vehicles are removed by the scrap metal hauler and then transported to a recycling or
disposal facility.
Tires generated in the County are shipped to O`ahu for crumbing and subsequent blending with coal at
the AES Hawaiʻi Inc. coal-fired power plant or processed in the H-Power waste to energy facility (City
and County of Honolulu. 2017). A small percentage of used tires are recycled for use in artistic or
industrial products. At least one business in the County has conducted a pilot project that mixes scrap
tires and concrete to create blocks for landscaping walls or fences. Nationally, markets are increasingly
being developed to use recycled products from tires, including steel alloys from belted tires, rubber
products such as playground surfaces or mats, and landscaping products. Local markets for scrap tires
are, however, still limited.
Although tires are relatively inert and do not break down quickly when discarded in the environment,
discarded tires can trap rainwater and provide an environment that mosquitoes, vermin, or invasive
species can thrive in, creating a public nuisance or potential public health concerns. The County will
continue to promote tire recycling best management practices in its public education and information
programs.
7.2.9 White Goods (Large Appliances)
White goods (large appliances) consist of used appliances including dishwashers, ranges, refrigerators,
water heaters, freezers, and other similar domestic appliances. According to the EPA, steel and iron are
the predominant materials in major appliances, and the recycling of these materials avoids the
environmental impacts associated with the mining and processing of virgin material (EPA 2016a). Thus,
2019 Integrated Solid Waste Management Plan Update
County of Hawaiʻi
August 2020 7-5
recycling at scrap metal facilities is highly encouraged. Big Island Scrap Metal, located on both sides of
the island, Hilo and Kona, currently accepts these items.
The County also promotes on its
website the Refrigerator Trade-Up
“Rid-A-Fridge” Program that offers
residents the option to replace
and dispose of energy inefficient
appliances, contingent upon
funding availability. Through this
program, rebates are offered to
residents to replace their white
goods with more updated and
efficient models.
Residents may also drop off
unwanted white goods at various
recycling and transfer stations
(Exhibit 7-3). Since 2009, the
County has expanded their white
goods recycling program by
adding reuse facilities to seven more recycling and transfer stations. Drop-offs are allowed at other
recycling and transfer stations to keep them from ending up in the transfer trailers and the landfill. The
County employees monitor the number of white goods to remain in compliance with permit
requirements, and regularly load and recycle them at a scrap metal facility. At those facilities, freon is
recovered and recycled in accordance with federal law from appliances such as refrigerators, freezers,
and air conditioners.

Some retail outlets will pick up used appliances and transport them to scrap metal facilities when a new
(replacement) appliance is purchased with the delivery option. However, delivery to remote areas of the
island such as North Kohala or Ka`u is not offered by most retail outlets.
The difficulties associated with transporting bulky items such as white goods and limited recycling
options may consequently lead to Illegal dumping by residents. Options to improve the white goods
disposal process include changing the operation permit for more recycling and transfer stations to
accept residential white goods, establishing additional targeted collection days and locations, or having
mobile collection events.
7.2.10 Abandoned Vehicles
Abandoned vehicles are managed by the County Abandoned Vehicle Coordinator in conjunction with the
HCPD. According to HCC 24-199, abandoned vehicles (operational and non-operational) in public right-
of-way are subject to a $250 fine and vehicle removal-associated expenses.
Abandoned vehicles that have been reported to the HCPD are tagged, monitored, and evaluated to
assess if they are derelict. If after the monitoring period the vehicle has not been moved, it is considered
derelict; the vehicle is then hauled by a County-contracted towing company to one of the two waste
metal recovery facilities. If the vehicle is abandoned and not considered derelict, the vehicle is
impounded by the County, and an attempt is made to notify the registered owner.
7.3 Recommendations
The current program for special wastes is somewhat limited by the County recycling and transfer station
infrastructure. It was agreed through consensus of the SWAC to include functional elements necessary
for proper handling of special wastes in new facility plans or designs. Permits will have to be modified to
allow the handling and temporary storage of special wastes at recycling and transfer stations, and staff
will require training to implement new programs correctly. Further study will be required to develop
programs that are adequately protective of human health and the environment. Based on the analysis
presented above, and discussions with the SWAC, the Plan recommends the following to improve the
special waste program:
1.Continue to integrate the Do-It-Yourself Used Motor Oil program within the County’s public
education and information program.
2.Increase the number of recycling and transfer stations that accept white goods. Continue to
explore the feasibility of removing the freon at the site to simplify the handling, loading, and
transport of white goods.
3.Continue to ensure that recycling facilities responsible for dismantling of white goods are
trained properly for the recovery and recycling of freon-containing appliances.
4.Continue to promote tire recycling best management practices within the County’s public
education and information program.

8.COLLECTION AND TRANSFER
8.1 Introduction
The County currently operates a network of 22 recycling and transfer stations. The County contracts
with private firms to transport recyclables from most of the stations to privately operated processing
facilities.
Municipal waste is transported by the County’s Department of Environmental Management (DEM) Solid
Waste Division (SWD) staff to the West Hawaiʻi Sanitary Landfill (WHSL).
This chapter describes current conditions of the existing solid waste collection and transfer system
within the County, identifies current issues and concerns, and presents options and recommendations
for achieving the County’s solid waste collection and transfer goals.
8.2 Background
The County of Hawaiʻi developed the transfer station system in the 1970s to provide a transition from
operating local dump sites to instituting a more centralized landfill system. The transfer stations were
initially constructed as inexpensive, temporary facilities to fulfill the immediate needs of residential
users by consolidating smaller residential loads into combined larger loads for transfer to landfills. The
recycling component of the transfer station was incrementally added beginning in the early 2000s, and
the County now refers to the facilities as “recycling and transfer stations.”
The 22 recycling and transfer stations operate under Solid Waste Management Permits issued by the
Hawaiʻi Department of Health (HDOH).
8.3 Review of 2009 Plan Update
Exhibit 8-1 provides a summary of the recommendations presented in the 2009 Plan update relative to solid
waste collection and transfer, and a description of the actions taken to date to achieve each recommendation.
Exhibit 8-1. Status Update of 2009 Plan Recommendations for Collection and Transfer
2009 Plan Update Recommendation Status
1)Retain the County’s system of recycling and
transfer stations. 2) A component of retaining the
system includes completing upgrades to address
structural deficiencies. 3) Provide expanded services
in support of zero waste initiatives.
1) County’s MSW system retained. 2) Upgrades to several
recycling and transfer stations completed (see below).
3)Zero Waste initiatives include plastic bag/polystyrene
foam ban, addition of seven reuse centers.
1) Reconstruct one or more recycling and transfer
stations annually, including a new South Kona
recycling and transfer station at Ocean View. 2) The
County should also consider installing compaction
units for recyclables at selected stations. Consider
adopting a "satellite" system where compactors
would be installed at selected stations, which would
accept uncompacted recyclables from nearby
stations lacking compactors.
1) Reconstructed Pāhoa, Glenwood, and Volcano recycling
and transfer stations. Currently reconstructing Wai`ōhinu/
Ka`u recycling and transfer station. The Ocean View
Recycling and Transfer Station is being constructed.
2)Recycling compactor system not implemented.

County of Hawaiʻi
Exhibit 8-1. Status Update of 2009 Plan Recommendations for Collection and Transfer (continued)
8-2 August 2020
2009 Plan Update Recommendation Status
Implement full-time staffing and reduced operating
hours at recycling and transfer stations; consider
closing one or more stations.
Public demand requires more recycling and transfer
stations and longer days and hours of operation. Current
funding provides limited staffing levels.
Develop a system to license private collection firms.
In this program, all firms that collect garbage from
residents or businesses would be required to register
vehicles, document that the vehicles meet safety
requirements, and pay a nominal licensing fee (to
cover the cost of licensing).
Currently, collection firms must have an account/permit to
dispose at the landfill. A license program has not been
developed.
Change permits to allow small commercial
businesses to drop off recyclables at County recycling
and transfer stations. These permits would make it
much more convenient for small businesses in rural
areas to recycle. To ensure efficient and safe
operations, only trucks below a certain size threshold
(for example, less than 1 ton) would be allowed to
use the stations.
The increased cost of processing the material is a concern.
The County has not added enough funds to take material
from the businesses.
Conduct an operational efficiency analysis. Did not implement. No funds were available for
operational efficiency analysis.
Develop a base yard facility and equipment
maintenance facility for transfer vehicles at the SHSL.
Constructed a new South Hilo base yard, but not the
maintenance facility.
8.4 Existing Conditions
Currently, there is no curbside recycling or garbage pickup provided by the County. Most island
residents use the network of 22 recycling and transfer stations to dispose of their rubbish. The recycling
and transfer stations are geographically distributed for the convenience of island residents. A map
showing the relative size of each station as correlated to garbage received (FY 2017–18) is included in
Exhibit 8-2.
Private companies provide curbside pickup within limited geographic regions of the island for a fee.
Based on residential credit information from the County 8, it is estimated that about 6,000 households
currently subscribe to curbside service. This represents approximately 9 percent of the estimated 66,094
occupied households in the County in 2017. Fees for curbside collection quoted by private collection
firms appear to range between $20 and $40 per household per month. In 2018, the Honolulu, Kaua’i
County, and Maui County curbside pickup costs for residents were approximately $10, $12, and $18,
respectively. There are several companies that collect garbage from businesses and institutions in the
County. Collection rates charged vary by company, the type of service provided, and the distance from
the collection point to the landfill.
Use of the recycling and transfer stations to drop off recyclables or garbage is currently free for residents.
8 The County provides credit against tipping fees to collection firms that document waste that is collected from
residences.

8.4.1 Recycling and Transfer Station Features
The 22 recycling and transfer stations managed by the County vary in size, population served, tonnage
of waste collected per day, types of waste accepted, and hours of operation. Site characteristics for each
recycling and transfer station are presented in Exhibit 8-3.
Except for Miloliʻi and Ocean View recycling and transfer stations, rubbish is compacted typically three to
four times per day by SWD facility attendants who distribute their time among the different facilities. The
Miloliʻi Transfer Station has a roll-off container that is hauled twice per week to the WHSL by the SWD.
Recycling and transfer station attendants clean and maintain the stations, operate the compactors,
periodically monitor haulers for prohibited materials, and report any unusual activity at the stations.
The recycling and transfer stations are permitted to accept only residential rubbish; commercial and
hazardous wastes are prohibited at all stations. For each volunteer event, nonprofit organizations and
community groups are required to get a waiver to dispose of material at the recycling and transfer
stations, which can be time consuming and inconvenient. Commercial businesses frequently use the
stations due to a lack of resources for enforcement and/or suitable alternatives for solid waste disposal.
Without adequate security measures and enforcement, it is difficult for the County to ensure that all
permit requirements are being met. Currently, 21 of the 22 stations are gated and have part-time
security guards.

At 18 recycling and transfer stations the County
employs a 2-bin system for recycling, with
limited stations providing a separate bin for
cardboard. This system consists of separate roll-
off containers to accommodate the recyclables.
Currently, most stations have stairs and
platforms to allow convenient customer access
to the recycling bins. Select stations offer a HI-5
redemption center, and reuse opportunities
and/or facilities for the recycling of green waste
and metals. The recycling services provided at
each station are shown in Exhibit 8-4. Several of
the recycling and transfer stations are used
illegally by private recyclers or community groups to drop off recyclable materials.
The County facilitates the use of the recycling and transfer stations as collection points for recyclables to
the extent practicable, and intends to eventually upgrade all of the recycling and transfer stations to
enhance recyclable collection capabilities.
At the stations, residents deposit garbage into chutes that lead to truck-mounted, compacting containers
(except Pāhoa), which are then hauled by SWD staff to the landfill. The County operates and maintains
stationary compacting units, truck-mounted compacting units, and a fleet of trucks and compacting
containers utilized in the operation of the recycling and transfer station system, and provides part-time
security monitoring.

County of Hawaiʻi

The County has placed a strong emphasis on waste diversion. Since 2009, the County has expanded its
green waste program. Green waste bins have been added to various recycling and transfer stations. In
2013, EHOF and WHOF began operation. In their first year, these facilities collected 40,465 tons of green
waste representing 63 percent of diverted waste from the SHSL and
WHSL (County of Hawaiʻi DEM 2017a). Although these facilities
accept yard trimmings and untreated wood pallets, they do not
accept food waste. According to the EPA (EPA 2018c), food waste
composes 15.1 percent of MSW—a value exceeding yard trimmings
(13.3 percent) and wood (6.2 percent). Thus, in 2014, a request for
proposals (RFP) was released for a compost and green waste
processing facility that would accept food and yard waste (East
Hawaiʻi Organics Facility). The County plans to develop the facility on
the east side of the island as early as 2020.
To further the philosophy of waste reduction and zero waste, the
County has also expanded reuse facilities. Reuse centers have been
installed at eight recycling and transfer stations (see Exhibit 8-3);
these facilities accept donated reusable items that are then sold for
reuse back to the public. Through reuse, negative environmental
impacts associated with landfilling and reprocessing are bypassed or
delayed. The County has garnered recognition for these improvements and updates. For example, the
Solid Waste Association of North America (SWANA) recognized the Pāhoa Recycling and Transfer
Station’s 2012 improvements for environmental and economic solid waste management. This station
accepts green waste, cardboard, glass, and scrap metal, and includes an onsite reuse center and HI-5
redemption center. Waste reduction is also achieved through the County’s white goods program;
residents may bring clean empty household appliances to 13 recycling and transfer stations (see
Exhibit 8-3).
8.5 Issues and Concerns
The County’s network of recycling and transfer stations provides convenient locations for County
residents to drop off recyclables and garbage. Residents who prefer curbside collection must make
arrangements with a local business providing the service.
When evaluating a curbside service program, the County would assess the need to continue operating
all 22 recycling and transfer stations. Curbside service would require significant additional capital start-
up and yearly operations costs, and the net cost increase could potentially be reduced by closing some
of the County’s existing recycling and transfer stations.
As discussed above, the County’s existing transfer system was established in the 1970s and most of the
stations require significant upgrades to address structural and functional deficiencies. As discussed in
Chapter 4 Recycling, Bioconversion, and Markets, it would also be desirable to provide additional
opportunities to divert waste from landfill disposal. Many such opportunities would require significant
and potentially expensive changes to the existing infrastructure and operations at County recycling and
transfer stations.

8.6 Curbside Collection Implementation Considerations
This section provides a discussion of a variety of issues that would be considered when evaluating the
merits of the County implementing a residential curbside collection service, including:
•Institutional approaches to service delivery.
•Funding options.
•Service levels.
•Collection technologies.
•Service frequency.
Many of these issues were also discussed in Chapter 4 Recycling, Bioconversion, and Markets.
References to this chapter will be made as appropriate.
8.6.1 Institutional Approaches to Service Delivery
In the United States, residential waste collection services are provided by both the private and public
sectors. Although there are numerous ways to group or categorize different ways of delivering waste
collection services, the four most common types of service delivery arrangements currently used in the
United States:
1.No government-organized collection service.
2.Local government owned and operated collection service.
3.Non-competitive franchise collection service with rate regulation.
4.Competitive contract collection service.
This section provides a brief discussion that highlights the features of each service delivery arrangement.
8.6.1.1 No Government-Organized Collection Service
This is the method of collection currently in effect in the County, where customers either deliver their
own waste to a processing or disposal facility, or select a private business to pick up recyclables and/or
waste at the curb. In many communities, “going to the dump” has long been part of a routine for some
residents. Many of these individuals would prefer to make the time to deliver waste materials on their
own rather than pay for collection services.
Historically, many communities have given residents the option to either sign up for curbside collection
services or to self-haul their materials. The main advantage to self-haul collection is that the (typically
smaller) percentage of residents who prefer to self-haul their waste may do so without being charged
for a service they do not want or need.
In most industries, having many firms compete for business tends to result in efficiencies and lower
costs for consumers. However, this is usually not the case for residential collection of garbage because
the benefits of competition are usually overcome by the inefficiencies of having multiple haulers driving
down the same street each day.
Trucks must drive greater distances between stops resulting in fewer stops per collection day leading to
increased costs. In other words, residential collection service costs can be reduced by regulatory
structures that ensure that a product or service is delivered by a single entity.
Another disadvantage of this arrangement is that billing and other overhead costs will also be higher
than in-service arrangements in which billing is combined with billing for other municipal services and
handled by a single entity. Finally, as communities grow and housing density increases, public health and
2019 Integrated Solid Waste Management Plan Update
County of Hawaiʻi
August 2020 8-11
social considerations become more important; garbage should be removed at least once every 7 days to
control flies and odors.
8.6.1.2 Local Government Owned and Operated
Local government collection is most typically performed by city
governments although collection is sometimes provided by counties,
especially where the county is the most basic level of government.
Advantages typically associated with local government collection include
the following:
•Local governments have some inherent cost advantages over
private firms, such as not having to pay income or other taxes
(the County does have to pay the General Excise Tax), the ability
to combine overhead costs for collection programs with other
existing programs (such as water, power, or sewer), not earning
profits, and lower costs of borrowing.
•Local governments may place a higher value on service to
customers than private firms.
•When local government collection is provided as part of a utility structure, rate increase
proposals are discussed in an open, public forum.
•Local government collection typically includes all households in a city or county allowing for
increased efficiency through the economics of contiguity (the contiguous alignment of
customers along a service route), and for larger jurisdictions, potential economies of scale.
While local government has some inherent cost advantages, the cost of local government collection is
often higher than when collection is provided by the private sector. A comprehensive national survey of
collection practices found that local government and privately provided service were of equal cost, on
average, for smaller local governments with a population of less than 20,000. And the survey found that
privately provided service with exclusive collection territories was significantly less costly (up to
37 percent) for larger jurisdictions with populations of more than 50,000 (Stevens 1980). According to
certain reports, privatization of MSW collection may result in a cost savings ranging from 20 to
40 percent for local government (NSWMA 2011). However, privatization may not always be less costly
than government collection, as the weak competition between collection companies often reduces cost
savings. In fact, a meta-analysis study conducted between 1960 and 2008 across the United States and
nine other countries determined no cost difference between public versus private collection (Bel and
Warner 2008).
Some other factors that can lead to inefficiency and higher costs for local government collection include:
•Civil service requirements can hamper the ability of supervisors to motivate employees and, if
necessary, terminate underperforming employees.
•The lack of the profit incentive removes a powerful motivator toward efficiency.
•Work rule requirements can make it much more difficult for public sector managers to affect a
flexible response to changed conditions.
•The initial cost to purchase vehicles and containers and subsequent operation and maintenance
costs can be difficult for some communities to finance.
While local government collection can be cost competitive with the private sector, there are many
documented cases where local government has cut collection costs significantly by contracting out
collection services (Kenny 2013). In summary, it is likely but not certain that local government collection
2019 Integrated Solid Waste Management Plan Update
County of Hawaiʻi
8-12 August 2020
would be somewhat costlier than collection provided by the private sector in the County. If the County
were to establish a collection service, it would be critical to ensure good, experienced, proactive
management, and the use of appropriate incentives to motivate the behavior of collection personnel.
8.6.1.3 Non-Competitive Franchise with Rate Regulation
In this type of service arrangement, collection is provided by private firms holding franchises that give
them an exclusive right to collect waste from all residences within a specified geographic area. The non-
competitive aspect of the franchise means that rates are negotiated between the hauler and the state
or local government. This is a common arrangement in many communities in the United States. As an
example, in the state of Washington, hauler rates are regulated by the Washington Utilities and
Transportation Commission (WUTC) for jurisdictions that opt for this collection arrangement.
This method of providing collection service can foster a sense of partnership between the private and
public sectors. It is one of the most flexible institutional arrangements, because there is usually an
ongoing mechanism for negotiation between the public and private sectors. If conditions change it is
often easier to make adjustments to service levels, or add additional services such as curbside recycling
programs than other types of service arrangements. For example, local government collection programs
are often difficult to change because of civil service agreements. Contract collection is inherently less
flexible because a good contract specifies numerous details that are part of a legally binding agreement
that can be complex to alter. With an exclusive franchise, the jurisdiction retains flexibility to negotiate
change, and the efficiency advantage of contiguous routes.
One disadvantage associated with non-competitive franchises is the lack of competition to establish a
true, baseline cost of service. Without competition, local governments must rely on various regulatory
measures, rate comparisons with similar-sized operations, auditing methods, and negotiating
techniques to try and mandate that collection service providers establish reasonable pricing for services.
Often, these efforts result in only modest success; thus, competitive contracting for collection services
often is cheaper than a non-competitive franchise collection service. Finally, it is often difficult and
costly for governments to secure the expertise to effectively regulate the rates charged by haulers.
8.6.1.4 Competitive Contract Collection Service
The competitive contract arrangement refers to a system in which a city or county goes through a
competitive selection process and awards a single contract to the successful firm for the exclusive right
to provide collection services in a designated area for a specified period. Assuming there are multiple
firms competing for the business, contract collection for exclusive collection zones usually result in
lower prices for residential collection services than the other institutional arrangements. This occurs
because firms must keep their prices low to be competitive.
However, contract collection is not always the lowest cost institutional arrangement for collection. Higher
costs can occur if local governments do not use adequate care in the development, implementation, and
administration of the contractual relationship with its contractor. Three key factors that must be present
for a community to ensure low cost, high quality service from a competitive contract:
•The procurement process must be structured to ensure that multiple firms bid on the collection
zones, and that multiple firms will be willing to bid once the initial contract ends and must be
rebid.
•The procurement documents and, in particular, the contract must precisely specify the services
required.
2019 Integrated Solid Waste Management Plan Update
County of Hawaiʻi
August 2020 8-13
•The contracting jurisdiction must devote significant resources to craft a good contract. Once the
contract is in place, additional resources are needed to actively monitor and manage contractor
performance.
Some disadvantages of contract collection include the following:
•There is added risk associated with contracting because it is difficult to foresee the future and to
devise a contractual relationship that protects the interests of the contracting jurisdiction yet
leaves the private sector the flexibility to profitably and creatively provide the requested
services.
•Customer service can suffer if the contract does not clearly specify service requirements and/or
if the contracting jurisdiction does not enforce contractual requirements.
•In some cases, intense competition or intra-firm marketing pressures result in firms bidding
prices below the true cost of service. In such cases the local government benefits from low
prices; however, there can be protracted difficulties in getting the contractor to perform in
accordance with the contract.
The County would need to address many issues when implementing curbside collection using
competitive contracts including the following:
•Deciding how many collection zones and contracts are appropriate to establish. To ensure long-
term competition and economies of scale, the County would need a minimum of two zones
awarded to two different contractors and probably a maximum of three or four zones.
•Developing a complex request for bids or proposals including a good contract that spells out
clearly the services to be performed and penalties for non-performance.
•Communicating daily with haulers about ongoing billing, customer service, and equipment or
logistical issues.
•Monitoring contractor performance.
In the County of Hawaiʻi, a 2004 Supreme Court of the State of Hawaiʻi decision affirmed the right of
private sector unions to provide services traditionally performed by the public sector. The Hawaiʻi State
legislature has made provisions to allow for managed competition, in which both the public and private
sectors could compete to provide public services, such as collection (Supreme Court of the State of
Hawaiʻi 2004).
However, there is no process yet established for such a competition, and it is highly likely that an
attempt to enact such a process would result in litigation with an uncertain outcome.
8.6.2 Collection Technology
Curbside collection can use various levels of automation. The traditional
approach to collection relies on crews of two to three people to manually
toss refuse into collection trucks. To reduce crew sizes, some communities
have implemented semi- automated or fully automated collection systems.
This requires providing each household with a wheeled container that is
rolled to the curb on collection day. Automated collection trucks have
lifting mechanisms that empty the rubbish into the truck. This section
discusses the relative merits of manual, semi-automated and fully
automated collection systems, and their applicability to the County.
2019 Integrated Solid Waste Management Plan Update
County of Hawaiʻi
8-14 August 2020
8.6.2.1 Manual Collection
Manual collection is the traditional method of collecting materials at curbside. Waste is typically
collected by two- or three-person crews in rear-loaded and side-loaded collection vehicles. This
arrangement is a common method of collection in the United States, although in some rural areas where
the distance between stops is great, one-person crews are sometimes used. Side-loaded vehicles use
compartment openings on the driver side of the vehicle rather than at the back, and therefore the driver
or crew member does not have to walk as far to unload waste into the truck. For this reason, side-
loaded vehicles can be operated somewhat more efficiently than rear-load vehicles when smaller (one-
or two-person) crews are used.
To reduce labor costs, many communities are modifying their solid waste collection program to add
some level of automation. According to the National Waste and Recycling Association, in 2013,
approximately half of all newly purchased waste collection vehicles were fully automated and manned
by one person (Rogoff 2015). In Hawaiʻi, the counties of Honolulu, Kaua’i, and Maui have transitioned
from manual collection to fully automated collection (City and County of Honolulu 2018b; County of
Kaua’i 2018b; Maui County Government 2008).
Automated collection vehicles reduce labor costs by allowing for smaller crews; however, this is at the
expense of higher capital investment in trucks. Therefore, automated collection is best suited to areas
with relatively high labor costs, and manual collection is best suited to areas with relatively low labor
costs. Insurance premiums are also higher with manual collection because many workers suffer injuries
to backs and shoulders by repetitively lifting waste into the truck. Thus, the appropriateness of manual
versus automated collection will depend on the relative cost of labor plus associated costs versus capital
costs, and the characteristics of local collection routes.
8.6.2.2 Semi-Automated Collection
In semi-automated systems, the collector wheels the container
from the curb to the rear or side of the truck and attaches the
container to an automated hydraulic dumping unit (tipper).
These systems require special containers that are designed to be
compatible with the lifting units. Virtually all the heavy lifting
associated with rubbish collection is eliminated; thus, worker
fatigue and injury is reduced, and the vehicles can be operated by
crews as small as one person. Considering that solid waste
collectors have the highest injury rate of any industry nationally,
the benefits associated with eliminating lifting can be significant.
Although semi-automatic systems require more time per pickup than manual loading, service time per
crew member can decrease because semi-automated systems usually allow for a sizable reduction in
crew size. The wheeled containers used with semi-automated and fully automated systems are often
perceived by the customer as a more convenient, cleaner collection system, resulting in decreased litter.
For rural customers with long dirt driveways, larger, wheeled containers may be a drawback because
they are difficult to load into a personal vehicle to take to the set-out location. In rural areas, customers
could be allowed to set out smaller, 30-gallon cans to make it more convenient.
Semi-automated collection has been successful in some communities but unsuccessful and ultimately
canceled in others. This type of collection service typically failed due to slower route times, overly
stringent container set-out requirements, higher vehicle and container costs, or a perceived reduction in
the incentive to recycle because of the larger can sizes. Municipalities with successful semi-automated
2019 Integrated Solid Waste Management Plan Update
County of Hawaiʻi
August 2020 8-15
collection programs devised ways to work around these problems. In some cases, it has been
determined that despite the challenges, overall collection costs were less than manual collection
because of the reduction in crew sizes, decrease in insurance premiums, and reduced injury rates.
Compared with manually loaded vehicles with two- or three-person crews, semi-automated collection
results in longer route times and higher capital costs. Manually loading rubbish into trucks from cans is
faster than using semi-automated loading systems. Labor costs can be reduced by reducing the size of
the crew per truck; however, capital costs are increased because more trucks may be required to pick up
the same quantity of waste.
Semi-automated (and fully automated) collection would be challenging to implement in rural areas of
the County because of factors not conducive to automation, including:
•Unimproved roads.
•Lack of curbs or sidewalks for set outs.
•Steep slopes.
•Dense vegetation.
A focused study would be needed to evaluate if semi-automated or fully automated collection
(described below) could be implemented effectively in the County.
8.6.2.3 Fully Automated Collection
Although fully automated systems are not as common as semi-automated systems, the number of
communities throughout the country that use fully automated collection
vehicles is growing. Fully automated systems use one-person side-loading
vehicles equipped with a lifting mechanism (collection arm) on the side of
the vehicle. The operator pulls up to the container at the curb and controls
the entire loading operation from the right-hand driver’s seat. The
collection arm allows the operator to grasp, empty, and return the
container without leaving the truck cab. In certain cases, such as
improperly positioned or obstructed containers, the operator may have to
leave the cab to respond to a problem.
Fully automated systems have similar advantages to the semi-automated
systems discussed in the previous section. Because virtually all lifting is
eliminated, the costs associated with worker injury and fatigue are greatly
reduced. In addition, there is usually an improvement in collection labor
efficiency because fully automated systems use a single person on each
truck and the driver does not have to get out of the truck as frequently.
Benchmark fully automated collection systems can collect from more than 800 households per day per
truck with a single driver. Since commercial containers compatible with fully automated systems are
available up to 300 gallons, some communities have lowered collection costs by incorporating
commercial accounts on residential routes.
Fully automated systems require cooperation by residents to set out containers in a prescribed way.
Implementing fully automated systems presents additional physical constraints as well. Single side of the
street routing is required (which will increase miles driven and drive time between accounts). Parking
restrictions may need to be instituted, and obstructions (for example, trees, and utility wires) may
present problems in certain areas.
2019 Integrated Solid Waste Management Plan Update
County of Hawaiʻi
8-16 August 2020
Compared with manually loaded vehicles with two- or three-person crews, route times will be longer
and capital costs will be greater with either semi- or fully-automated collection.
However, labor costs would decline by reducing crew sizes to one (plus extra replacement drivers for sick
days, vacation, and holidays). The total operational collection cost will depend on a community’s labor
costs and route structure. Because capital costs will be higher and route times slightly longer, the main
source of savings compared to manual collection is in labor. Communities that have shifted to automated
collection typically have relatively high labor costs. This is an important factor in case studies of
automated collection that show an overall reduction in collection costs.
Compared to semi-automated collection, fully automated collection requires trucks that are costlier
with higher maintenance requirements. Those costs are typically overshadowed by the cost savings that
results from the reduced time per stop. Thus, in most cases, fully automated collection appears to be
more advantageous than semi-automated collection.
8.6.3 Service Levels
Curbside service is generally provided in one of two ways:
•Subscription basis—where residents have the option to either subscribe to the service or not.
•Universal collection—where all residents in a jurisdiction or a sub-area of a jurisdiction are
charged for curbside service regardless of whether they use the service.
The advantages of a subscription service are that residents are given a choice of whether to pay for the
service. The disadvantage is that it makes collection costlier on a per household basis by lengthening the
distance between stops on a route. Universal collection has just the opposite set of advantages and
disadvantages: residents no longer have a choice and are required to pay for a service; yet, per
household costs are lower.
This issue was discussed in Chapter 4 Recycling, Bioconversion, and Markets. The County is
predominantly rural in character with relatively small urban and suburban areas in Hilo, Kailua-Kona,
Waimea, and a few other locations. Many of the rural areas
within the County have steep, unimproved roads not
suitable for collection vehicles. Thus, mandatory curbside
collection for all County residents is likely to be impractical.
Further, longer distances between collection stops will occur
in many of the geographically dispersed small communities
in the County. A voluntary subscription service, for which
not all residents would sign up, would potentially make the
distance between collection stops even longer. While there
is no binding constraint against implementing a subscription
service, the fact that the County has many geographically
dispersed rural communities suggests that designating
specific geographic zones where curbside service would be
mandatory would make more sense than mandating island-wide collection.
8.6.4 Service Frequency
Most collection systems now include both garbage and recycling and many offer green waste services.
Some communities are taking the next step toward zero waste and are diverting food and other organics
from the garbage at curbside. Considering the County’s commitment to increasing landfill diversion, if
2019 Integrated Solid Waste Management Plan Update
County of Hawaiʻi
August 2020 8-17
the County elects to make the substantial commitment to begin offering curbside collection services, it
would make sense to offer curbside collection of recyclables.
Some communities in hot and humid climates offer garbage collection service twice weekly. This is
significantly more expensive than weekly collection and this practice seems to be less common; weekly
collection of garbage is typical in most communities.
Recyclables are typically collected either weekly or bi-weekly. Weekly collection generally is costlier and
may result in higher diversion from the landfill. However, as discussed in Chapter 4, the evidence of
increased diversion from weekly collection versus bi-weekly collection is weak and is not consistent in all
jurisdictions. Organics (e.g., yard and food waste) collection services are offered in a wide variety of
service frequencies including weekly, bi-weekly, monthly, and seasonally.
The most aggressive approach to diversion at curbside is a three-stream system in which food and other
organics (which could include green waste) is collected weekly and garbage and recyclables are collected
either weekly or on alternative weeks.
8.6.5 Funding Options
There are several ways that the County could pay for a curbside collection service, including:
•Property taxes.
•Direct billing.
•PAYT program.
8.6.5.1 Property Taxes
This is how solid waste management expenditures are currently funded. Thus, it would be relatively
simple for the County to continue with this method and would potentially streamline implementation of
a new service.
The main disadvantage of this funding method is that it would provide no information to customers
about the cost of the program. The lack of information for consumers about program costs would
indirectly eliminate one way of providing incentive to program managers to keep service costs low. To
educate the public on program costs, the County could separate the costs of waste management
services on property tax bills. This would be relatively simple for the County to implement and would
provide some information to customers about the cost of curbside collection, and potentially other
waste management services.
8.6.5.2 Direct Billing
The County could provide curbside collection and other waste management services in a similar manner
to utility services, such as water or electricity, and send bills directly to customers. This is a very common
arrangement in the United States. The main advantages of this type of system are to provide better
information to customers about the cost of the collection service, and to indirectly provide incentives to
provide services more efficiently.
To implement this type of system, the County would need to hire personnel, establish computer-based
systems for the program, and conduct considerable public education. Ongoing customer service would
need to be provided to address disputes about services and billing, and for collection of unpaid bills.
2019 Integrated Solid Waste Management Plan Update
County of Hawaiʻi
8-18 August 2020
8.6.5.3 Pay-As-You-Throw
As discussed in Chapter 3, Source Reduction, PAYT can take many forms including using a variable can,
metered bag, or metered tag system. The key aspect of this system is to charge a progressive rate for
each additional garbage unit collected above the basic service level (for example, one can per week). In
other municipalities, PAYT has proven to be a highly effective method of reducing waste and increasing
the use of recycling and organics diversion programs.
Implementing a PAYT system for residential garbage collection service or at existing recycling and transfer
stations would require implementation of an aggressive public education and information campaign to
ensure that residents understand the rationale for implementing the PAYT program. Significant upfront
planning would be required to assess a wide range of implementation details. The County would need to
establish billing systems, a customer service organization, and modify its financial systems to
accommodate this new service. The County could elect to assess the potential for reducing property
taxes as an offset to the new revenue source. See Chapter 3 for a dedicated discussion of PAYT options.
8.7 Options for Improvement
The County’s system of recycling and transfer stations is a unique system that has served the County
well for more than 30 years. Options for improving that system follow.
8.7.1 Add Curbside Collection
The challenges associated with implementing curbside collection of recyclables (as discussed in Chapter
4 Recycling, Bioconversion, and Markets) would also apply to collecting garbage. Mandatory curbside
collection of garbage for all County residents is impractical because of the County’s predominantly rural
character and the many areas with steep, unimproved roads not suitable for collection vehicles. Further,
longer distances between collection stops will occur due to the large number of geographically
dispersed small communities in the County. A voluntary subscription service, for which not all residents
would sign up, would potentially make the distance between collection stops even longer. For program
cost efficiency, it is recommended that this option include designated zones where curbside service
would be mandatory.
Cost Considerations. The cost of curbside collection of garbage would depend on many factors including
the type of collection vehicles used (manual versus semi-automated versus fully automated), the
number of rural households included in the program (increased distance between collection stops), and
the institutional arrangement (for example, public versus private). A collection study would be required
to further explore opportunities for this type of service.
The cost of curbside collection would be offset somewhat by reducing the amount of waste that would be
transported from recycling and transfer stations to landfills. This may be achieved by increasing the
diversion rate through increased recycling and composting endeavors. The County’s full complement of
recycling and transfer stations would be somewhat less necessary if curbside collection were implemented.
However, it should be recognized that the rural residents not easily served by curbside service are
dispersed geographically throughout the island and still need convenient locations to dispose of recyclables
and garbage.

8.7.1.1 Collection Sub-Options
This section explores several different opportunities for residential curbside collection as collaborated
between the County and the SWAC. While there are many possible methods of implementing collection
service, the sub-options considered in this section reflect current opportunities and constraints that
exist in the County, including:
•The County transfer system provides reasonably convenient service for all households, and
there is no County-sponsored curbside service.
•About 9 percent of County households receive garbage service from private companies that
compete for customers with little County involvement.
•Few companies currently provide curbside recycling for residences (in part because there are
very few locations they could take the materials collected).
•Universal curbside collection of garbage for all County residents is impractical because of the
County’s predominantly rural character and the many areas with steep, unimproved roads not
suitable for collection vehicles.
•State law may preclude the County from engaging in franchises or contracts with private sector
collection firms.
The following sub-options provide an increasing level of change, potential benefits and costs, and
implementation difficulty:
A.Retain existing system.
B.License all collection companies.
C.License existing collection companies and require every-other-week recycling.
D.County offer collection services using County crews.
E.Exclusive franchises for private sector collection.
Note that in all these options, collection service would be optional for residents. A universal collection
service would be more efficient than an optional service because it would result in more stops per hour
of collection. However, in most areas of the County the total cost for universal collection would probably
be quite high when combined with a means of providing service to the many rural residents that are
spread out widely throughout the County. To serve these residents, the County would need to retain
many of its existing stations (perhaps ten to 15 of the existing 22 stations) or provide an additional
collection service (such as bins located on main roads where residents could dispose of their waste). It is
possible that universal collection could be implemented in Hilo or in select areas on the western side of
the County at the same time recycling and transfer stations that serve those areas could be closed. This
could be evaluated at a later date; however, in most areas of the County, the sum total of universal
curbside collection and maintaining recycling and transfer stations for more rural areas is likely to be
cost-prohibitive compared to any advantages it might provide.
A.Retain Existing System
In this option, the existing system would be retained. Residents who would prefer curbside collection
would make arrangements with a collection company.
2019 Integrated Solid Waste Management Plan Update
County of Hawaiʻi
8-20 August 2020
This system would have the advantage of simplicity by just continuing existing practices at no additional
cost to the County: those living in more urbanized areas of the County have the service available to
them. Some disadvantages of this option include:
•Many areas of the County are currently not served because of the difficulty of profitably serving
customers outside of more densely populated areas.
•The current collection system is relatively inefficient with both low route densities and the
potential for multiple companies collecting from homes on the same street.
•This system is somewhat less compatible with recycling because persons receiving garbage
collection still would have to go to a recycling and transfer station to drop off recyclables.
•There is currently no standardization of services and no control over the type and condition of
vehicles used by haulers.
B.License All Existing Collection Companies
In this option, the County would pass an ordinance requiring all companies collecting garbage or recyclables
from residents to obtain a “material collection license.” The County would place certain conditions for
obtaining a license such as: paying a small annual fee, obtaining a “license sticker” to be displayed on each
vehicle used for collection purposes, and require proof of annual safety inspections of each vehicle.
The County could then assist in the promotion of collection service by licensed haulers by listing haulers
name and phone numbers on its website and in promotional material. This would inform the public about
the services available.
Other than requirements associated with licensure, collection companies would be free to engage in
operations as they see fit including where and when to offer service, the method of set-out, and the
price of the service.
There would be a small initial cost to prepare the ordinance and develop the licensing program, then a
small annual cost to license each vehicle. Part or all the annual cost of the program could be paid
through licensing fees.
C.License All Existing Collection Companies and Require Bi-Weekly Recycling
This option is similar to Option B, with an additional requirement that licensed haulers also offer a bi-
weekly recycling service, and submit documentation about the method of collection for County
approval. Materials collected must match the list of materials accepted in the County’s 2-bin recycling
system at its recycling and transfer stations.
To implement this option, the County would need to ensure there are places for haulers to deliver
recyclables; at a minimum, facilities would be needed on the west and east sides of the island. This
could be accomplished at the South Hilo sort station, or at a private facility or facilities on the west and
east sides of the island, and possibly Waimea.
This option would have the advantage of increased recycling. It would, however, increase the cost of
curbside service and probably result in some customers discontinuing collection service.
D. County Collection Services Using County Crews
In this option, the County would establish a new section of collections, and implement weekly curbside
collection of garbage and every-other-week collection of recyclables County-wide. Private sector
collection from 1-unit detached housing would no longer be allowed. It is assumed that this would be an
optional service available in areas of the County that could be reasonably served by a collection vehicle
(The 2009 Plan estimated that this would be about 70 percent of all 1-unit detached housing). The County
2019 Integrated Solid Waste Management Plan Update
County of Hawaiʻi
August 2020 8-21
would need to ensure that processing facilities are available for the west and east sides of the island, and
possibly Waimea. Collection options would need to be studied further including an economic analysis.
Customers who do not sign up for collection service would continue to use the remaining recycling and
transfer stations.
This option would have significant implementation challenges, some of which include:
•Hiring additional staff and procuring vehicles, carts, and equipment.
•Hiring consulting expertise with an individual or firm that has expertise in establishing a
collection operation.
•Establishing a billing mechanism to charge customers for the service.
•Establishing base yards for vehicles and carts in two or three locations on the island.
The County would need to estimate the cost of collection service, including start-up costs, and then
decide if it would be provided at cost or at a subsidized rate.
E. Exclusive Franchises for Private Sector Collection
In this option, the County would establish two to four franchises in which a collection company would
have the exclusive right to collect waste and recyclables from residential customers. Currently, it is
estimated that there are only about 6,000 customers that currently subscribe to collection service.
Considering that a single truck in a somewhat rural system can collect from 200 to 600 customers each
day on a route (depending on route density), the franchises would be small initially. Thus, more than a
few territories would be very inefficient to implement.
The service would be optional for residents, and presumably with an exclusive territory, costs would fall
compared to existing rates and the number of customers served would probably grow through time. All
companies would be required to offer a similar service, ideally using the same type of cart, with weekly
collection of garbage and every-other-week collection of recyclables. The County would need to ensure
that processing facilities are available for the west and east sides of the island, and possibly Waimea.
It is uncertain if this could be implemented under current state law. If the County were to implement
this option, the County would probably face a legal challenge from the union that serves County
workers. Thus, the County would need to test the legality of this approach. It might be able to proceed
by engaging in a managed competition process in which the County could also vie for franchises in
competition with private collection firms. The County would need to receive approval from the state to
engage in such a process. Thus, there is some legal work to be done prior to determining if this option
could be implemented.
Assuming implementing this option is legal, there are many ways that franchises could be awarded. It
would be challenging to develop a method of assigning franchises that is perceived as “fair” by all
existing collection companies: many (or all) of them are likely to oppose any particular franchise award
method. One approach would be to have firms bid a price per month for collection service in each zone
(i.e., bids would differ in each zone). The lowest price offered in a zone would be the winning bid. The
County could then set a County-wide rate that all residents would pay for collection services. The County
would then pay (or receive a payment from) the collection firm for the difference between the bid price
and the County-wide rate paid by residents for service in each franchise territory. The collection firm
would bill and collect the County-wide rate from residents who elect to sign up for the service.
The County would need to establish rate review capabilities and establish a process for firms to adjust
bid prices as costs change in the future. This would include reviewing the justification for any proposed
2019 Integrated Solid Waste Management Plan Update
County of Hawaiʻi
8-22 August 2020
rate increases. The County would continue to set the actual rate paid by residents. That rate could be
set so that the County breaks even or it could subsidize the collection service as it prefers.
In this option, some County recycling and transfer stations would remain open for those that prefer to
not pay for curbside collection.
The main advantages of this option are providing a way of improving the efficiency of service provision
(only one firm passing down a residential street), standardized services County-wide, increased
recycling, and flexibility and choice for residents.
Some disadvantages of this approach include: existing collection firms would lose the ability to provide
services as they see fit, and significant administration and legal expertise would be required for
implementation and to regulate rates. Implementing this approach would require project management
and specific expertise. It would probably take the County a year or more to put into place and would
probably require hiring a project manager and/or using consultants to provide specific expertise.
Cost Considerations. The cost of this option would depend on many factors as described above.
8.7.2 Change Permits to Allow Small Businesses to Recycle at
Transfer Stations
In the 2009 Plan, the County attempted to change the operating permits for each station from a
convenience center to a recycling and transfer station. This change would have eliminated a 40-cubic-
yard per day delivery maximum and would have allowed non-residential customers to access the
stations. Yet, the County encountered difficulties in the permit change process with the HDOH.
If the County reconsiders the permit change process, this option would allow non-residential customers
to use the recycling services at each recycling and transfer station. Non-residential customers would not
be allowed to deliver rubbish at the stations. This policy would provide more convenient recycling
opportunities for small businesses throughout the County within limits manageable by the County.
Cost Considerations. Under this option, the amount of recyclables that would be delivered to recycling
and transfer stations is uncertain. The County would anticipate increased costs associated with handling
and transportation for increased tonnage. The County would also need to invest in additional signage,
education, and promotion of this new policy. This would require the County to identify a system to bill
commercial haulers for recycling at the recycling and transfer stations. Although the commercial haulers
would be required to pay into the recycling system, they would ultimately realize a cost savings in the
reduction of landfill tonnage.
8.7.3 Continue Progress Towards Reconstruction of Stations in
Need of Repair
As shown in Exhibit 8-5, 11 of the County’s 22 recycling and transfer stations have major engineering
deficiencies requiring reconstruction, and another two have intermediate engineering deficiencies that
can be addressed while the station is operational. As described in Exhibit 8-5, the County has made
improvements to the following facilities since the adoption of the 2009 Plan:
•Glenwood–Reconstructed in 2015.
•Kea`au–Remodeled in 2011.
•Kealakehe–Reconfigured and repaved in 2014.
•Ocean View–Planned and designed, phase 1 construction in early 2019.
•Pāhoa–Reconstructed in 2011.
2019 Integrated Solid Waste Management Plan Update
County of Hawaiʻi
August 2020 8-23
•Volcano–Reconstructed in 2015.
•Waimea–Remodeled and reconfigured in 2010.
•Wai`ōhinu–Awarded contract for reconstruction in 2019.
Cost Considerations. If the County plans to implement a curbside service program, station upgrades and
reconstruction would be planned with this service in mind.
8.7.4 Increase Attendants’ Monitoring of Recycling and Reduce Operating
Hours at Recycling and Transfer Stations
The County could improve recycling by increasing attendants’ presence at the recycling roll-offs at each
station. The attendants would encourage customers to separate recyclables and provide information
about different ways residents could reduce the amount of waste going to landfills.
Currently, the County stations are open for 12 hours (except for Hilo [10.5 hours], Ocean View [8 hours]
and Miloli’i [sunrise to sunset]). The feasibility of reducing operating hours is challenging because the
County has concerns about reducing operating hours due to high public demand for disposal service.
The County could consider conducting a customer survey to provide feedback regarding staffing levels
and hours of operation to understand the needs of the customers and the cost of operation. Past
surveys have shown customers want increased hours for recycling and transfer stations however
including survey questions regarding additional recycling information/education at the sites would help
define future needs.
Cost Considerations. The cost of the initial survey to the residents would be a nominal fee. If it results in
the County providing full-time attendants at each station with existing staff, there would be station
attendant staff that could perform functions currently done by private security guards. Thus, the County
could significantly reduce or eliminate the cost of employing private security guards.
8.7.5 Add Full-Time Attendants, Reduce Operating Hours, and Implement
PAYT at Recycling and Transfer Stations
As discussed in Chapter 3, PAYT systems provide a powerful incentive to reduce waste and increase
reuse and recycling. It is possible that the introduction of a PAYT system at recycling and transfer
stations would be a step in incentivizing a curbside collection program. This option includes a PAYT
program, with full-time attendants and reduced operating hours.
The County would need to devote considerable upfront resources to educate residents about the
reasons for the new program and to explain how the new program works.
Further, it is recommended that this type of program be phased in with a 3- to 6-month grace period
during which bags or tags would be collected; however, no one would be turned away for not using the
appropriate bag or tag.
Illegal dumping is always a concern, although results from around the country have shown that long-
term increases in illegal dumping from PAYT programs are rare. The County may need to consider
increasing enforcement authority for the DEM or other County agencies to allow them to levy fines
against those caught engaging in illegal dumping practices.
Cost Considerations. See Chapter 3, Section 3.5.6.1 for details on the implementation of PAYT at
Recycling and Transfer Stations, including cost considerations.

County of Hawaiʻi
8-24 August 2020
8.7.6 Reduce System Costs by Closing Select Stations and Reducing
Operating Hours
In this option, the County would close some stations and reduce the operating hours of some stations
that remain open. The money saved could be used to increase waste reduction, reuse, and recycling or
used to lower the amount of money collected from property taxes for solid waste management purposes.
This option would include closing the following ten stations (Exhibit 8-6):
Exhibit 8-6. Station Closure Options
Closed Stations Closest Remaining Station(s)
Glenwood Volcano
Honomū Laupahoehoe, Hilo
Kalapana Pāhoa
Ke`ei Keauhou
Miloli`i Keauhou, Oceanview, Wai`ōhinu
Pa`auilo Honoka`a, Laupāhoehoe
Pāhala Wai`ōhinu
Pāpa`ikou Hilo
Puakō Waimea, and new facility planned at WHSL
This option would require an aggressive public education program that stresses the reasons for closing
some stations. As discussed above in the PAYT option, the County would need to educate residents and
increase enforcement to prevent illegal dumping. It is likely that some residents would continue trying
to drop off waste at closed transfer stations for some time until residents become comfortable with the
new arrangement. The County would need to plan for this and increase its budget for enforcement and
cleanup crews.
Cost Considerations. With ten fewer stations, a reduction in operating hours, allowing for the added cost
of full-time attendants, and providing budget for increased enforcement, it is estimated that this option
could result in significant annual cost savings.
8.7.7 Lower Transportation Costs by Compacting Recyclables
In FY 2017–18, the County spent about $960,000 transporting recyclables from recycling and transfer
stations to processors. The transportation costs could be lessened thereby reducing the volume of
material transported by compacting recyclables prior to transportation from stations. Two possible
methods of compaction include:
•Convert one garbage chute to handle recyclables at larger stations with multiple garbage chutes
(Kea`au, Pāhoa, Hilo, Waimea, Kailua, Keauhou).
•Breakdown/flatten cardboard boxes.
•Use compactor drop boxes at stations for mixed recyclables.
2019 Integrated Solid Waste Management Plan Update
County of Hawaiʻi
August 2020 8-25
8.7.7.1 Converting One Garbage Chute to Accept Recyclables
In this option, for stations with more than
two chutes, one chute would be designated
for accepting recyclables only as depicted in
the adjacent photo. Once dropped into the
chute, materials would be compacted in the
County’s 75-yard compaction trailers, using
the same operational methods currently
used for garbage.
The Kea`au, Waimea, and Keauhou stations
each have two chutes for garbage, the Kealakehe (Kailua-Kona) station has three, Hilo station has four,
and Pāhoa has two transfer trailers. Where only two chutes are available, it may be difficult to devote
one chute entirely to recyclables; long lines may form during peak conditions for disposal. Signage would
need to be changed, public education would be needed, and a full-time attendant would need to be
present on-site to ensure that only recyclables went into the chute designated for recycling. This
concept might work better at the Kealakehe (Kailua-Kona), or Hilo stations where converting one chute
would leave multiple shoots still available for garbage. Transportation cost savings from compacting at
the Hilo Recycling and Transfer Station may be small because mixed recyclables are transported a short
distance for processing in Hilo.
In summary, this concept appears to be feasible at the Kealakehe (Kailua-Kona) station, and might be
feasible at the Kea`au and Waimea stations. The County would likely conduct a pilot program to test its
effectiveness.
8.7.7.2 Use Compactor Drop Boxes at Stations for Mixed Recyclables
The County could increase truck payloads and lower
transportation costs by installing stationary compactors
at each station for recyclables. This system would
include a compaction unit and a charging hopper (two
cubic yards is a typical size) that residents would place
their recyclables into. When the charging hopper is full,
an operator would activate compaction and material
would be pushed into an enclosed drop box.
For safety, the system should be key- or code-operated
so that only trained operators would be able to engage
the compaction unit.
Enclosed drop boxes come in many sizes, and a 40-cubic-yard box is recommended to allow containers
to stay at stations for longer periods of time before they needed to be hauled. The installation would
require pouring a concrete pad to support each compactor and building a safe and convenient platform
around the charging hoppers for customers. County equipment operators (or a station attendant) would
have to routinely operate the compaction units to compact recyclables as they currently do for the
County’s garbage trailers. In FY 2017–18, the uncompacted mixed recyclables hauled from recycling and
transfer stations averaged about 4.5 tons per 40-cubic-yard bin. This type of unit at County stations
could probably achieve an average compaction ratio somewhere between 3:1 and 5:1 for mixed
recyclables.
Mixed
Recyclables
Garbage
2019 Integrated Solid Waste Management Plan Update
County of Hawaiʻi
8-26 August 2020
Cost Considerations. Converting garbage chutes to accept recyclables would probably require one
additional site attendant at each station (to ensure that materials are placed in the proper chute). There
would be a small initial cost for extra signage, education, and promotion.
The cost of compacting recyclables would need to be taken into consideration. If the County were to
install one compaction unit at each station and purchase various containers, the total initial capital cost
would be properly budgeted. In subsequent years, amortization of these units and containers would also
be equated into future budgets. When considering the added annual maintenance cost of about 5
percent of capital and labor costs for staff, it is uncertain if installation of compactors at all stations
would be cost-effective given the current recycling rates at County recycling and transfer stations.
However, it is important to note that many options considered in the Plan update (such as mandatory
recycling, PAYT, allowing non-residential recycling) would increase the quantities of mixed recyclables
accepted at stations. The larger the volume of recyclable materials transported, the more likely
compaction will be cost-effective. Another option to consider is installing the units only at selected
stations. The County could adopt a “satellite” system with compactors installed at stations that would
accept uncompacted recyclables from stations more distant from processors.
8.8 Recommendations
Based on the analyses presented above and discussions with the SWAC, the Plan recommends the
actions listed below to improve the collection and transfer program. the recommendations discussed
below. Implementation issues related to these activities are discussed in Chapters 3, 4, and 5.
1.Retain the County’s system of recycling and transfer stations; however, also explore
alternative funding methods via a feasibility study as discussed in Chapter 3 recommendations
(Recommendation 2). Until a decision is made on the best method of collection and transfer,
the County will continue to maintain and upgrade recycling and transfer stations to address
structural deficiencies and provide expanded services to divert waste from the landfill.
Note: Chapter 10, Section 10.6 (Recommendation 1) discusses a Solid Waste System Financial
Analysis.
2.Reconstruct one or more recycling and transfer stations annually. The decision discussed
above to maintain the County’s recycling and transfer system will require repair and/or
reconstruction of the recycling and transfer stations. After considering other County funding
needs, it is recommended that the County fund at least one reconstruction each year.
3.Consider “Satellite” compaction units for recyclables at select stations. The County would also
consider installing compaction units for recyclables at selected stations. This would include
consideration of adopting a “satellite” system where compactors would be installed at selected
stations, and those stations would accept uncompacted recyclables from nearby stations with
no compactor.
4.Reduce operating hours at recycling and transfer stations and consider closing one or more
stations. Reduce operating hours at recycling and transfer stations, and consider closing one or
more stations. In Chapters 3, 4, and 6, a number of proposed programs are recommended for
implementation at County recycling and transfer stations. It will be imperative that County staff
are present during station operating hours to inform users of the various recycling, reuse,
organics, and other programs available. As more services are provided, it will become
prohibitively expensive to keep recycling and transfer stations open 10 to 11 hours per day, 362
days per year. The County could consider closing select recycling and transfer stations if the
2019 Integrated Solid Waste Management Plan Update
County of Hawaiʻi
August 2020 8-27
benefits of increased services in some areas are deemed to be less than the cost of providing
that service. To start this process, the County would consider conducting a customer survey to
provide feedback regarding staffing levels and hours of operation to understand the needs of
customers.
5.Change County code to allow small businesses to drop off recyclables at County recycling and
transfer stations within limits manageable by the County.
6.Enable non-profits and community organizations specifically involved with litter abatement to
drop off non-recyclables at transfer stations without the need for daily waivers or permits.
7.Conduct an operational efficiency analysis to lower costs. the County would continue to
monitor the cost of its recycling and transfer network, including contracting with a third party to
conduct an efficiency analysis and identify potential opportunities to lower costs.

9.RESIDUALS MANAGEMENT
9.1 Introduction
Residuals refer to materials remaining after source reduction, reuse, recycling, and bioconversion.
Residuals management is the final treatment and/or disposal of the waste that cannot be economically
used in any other way. The County of Hawaiʻi provides landfill disposal for residual materials at the West
Hawaiʻi Sanitary Landfill (WHSL) located in Pu`uanahulu. The South Hilo Sanitary Landfill (SHSL) reached
capacity and subsequently closed in 2019. Located near the closed SHSL, MSW and commercially
generated waste is now collected at the East Hawaiʻi Regional Sort Station (EHRSS) and routed to the
WHSL. For residents, the common forms of residual materials sent to landfill are household rubbish, or
municipal solid waste (MSW), and DIY construction and demolition waste. Businesses and institutions
send a wide range of different non-hazardous residual materials from their daily operations.
This chapter describes current conditions of the existing residuals management system within the
County, identifies current issues and concerns, and presents options for managing residuals after source
reduction, reuse, and recycling.
9.2 Review of 2009 Plan Update
Exhibit 9-1 below provides a summary of the recommendations put forth in the 2009 Plan update
relative to residuals management, and describes the actions taken to achieve each recommendation.
Exhibit 9-1. Status Update of 2009 Plan Recommendations for Residuals Management
2009 Plan Update Recommendation Status
Develop a conversion technology facility. Between 2006 and 2014, the County issued several RFPs to
vendors who could potentially design, construct, and operate a
waste to energy (WTE) facility. The County’s evaluation of
proposals during this time determined that a mass burn WTE
facility was the most commercially and technically feasible option.
The County rejected a proposal in 2008 due to higher than
expected costs. Advanced diversion technology (e.g., WTE,
pyrolysis) must demonstrate that it is environmentally and
economically feasible, and the technology has a verifiable and
viable commercial track record (a minimum of 5 years) for
handling of municipal solid waste, before it will be considered by
the County.
Truck waste from the SHSL to the WHSL. The County began trucking waste exclusively to WHSL in late 2019.
Investigate the feasibility and cost of expanding the
SHSL. to a northwest parcel adjacent to the landfill
or to a rock quarry located next to the SHSL site.

The County will continue to look at means and methods to
maximize the load.

County to conduct a more in-depth evaluation of the
feasibility and cost of a new lined landfill in the
existing quarry site adjacent to the current SHSL that
would provide an estimated fifty (50) or more years
of additional disposal capacity.
A study was performed and it was determined that this option is
unfeasible due to proximity to the airport, among other
considerations. Instead, residuals are shipped to WHSL.
County to prepare a master planning document for
the WHSL and SHSL facilities.
1) The County is preparing a plan focused on reconfiguring
circulation, scalehouse location, and other facilities in anticipation
for additional residuals entering WHSL from the SHSL. 2) In 2012,
the County commissioned a Hilo Landfill Feasibility Study. In 2017,
the Cover System Alternatives Evaluation for SHSL was prepared,
and in 2018 the EA and subsequent Finding of No Significant
Impact (FONSI) was issued by the County Department of
Environmental Management (DEM) on behalf of the South Hilo
Sanitary Landfill Final Closure. Because it was determined in the
Hilo Feasibility Study that expansion of the Hilo landfill is
unfeasible, there is no need to proceed with a master planning
document during this planning period. Near the conclusion of the
30-year monitoring and maintenance period of the closed landfill,
there will be a need to develop a plan on behalf of the future use
of this site.
County engage in a dialogue with other Hawaiʻi
counties about the potential for mutually beneficial
joint solutions.
Some contractual efforts with Waste Management have been
made between Hawaiʻi Community College, University of Hawaiʻi,
Kaua'i County, and County of Hawaiʻi
County conduct a feasibility study of remediating the
closed Kailua-Kona landfill.
The County is still dealing with ongoing issues associated with the
closed landfill’s subsurface fires. A feasibility study is still on the
horizon for the required 30-year post-closure remediation efforts.
9.3 Existing Conditions
Residual waste from the western part of the County is disposed of at the WHSL and waste from eastern
part of the County is brought to EHRSS and shipped to WHSL. Residential residual waste is accepted at no
charge at 22 recycling and transfer stations and transported by County Solid Waste Division (SWD) staff for
disposal at both facilities. In 2019, commercial disposal of residual waste generally required a landfill
disposal permit through the DEM and a landfill tipping fee of $110 per ton. Per Hawaiʻi County Code,
tipping fees may be waived when it is “in the best interest of the County,” including one-time events for
community organizations, nonprofit organizations, or private property owners who are remediating illegal
dump sites that they did not create. The status of each landfill is described in the following sections.
9.3.1 South Hilo Sanitary Landfill Closure
The SHSL is located in Hilo, approximately 1 mile east of Kanoelehua Avenue and one mile south of the Hilo
International Airport. The landfill, which closed to customers in late 2019, is accessed via Leilani Street and
an unnamed access road. The County of Hawaiʻi owns the SHSL, and the DEM estimates that the landfill
started operations in the 1970s. The landfill facility is located on approximately 40 acres, the majority of
which was used for municipal solid waste disposal. The landfill was established on a former quarry and is
unlined. The landfill accepted approximately 75,400 tons in FY 2017–18, an average of approximately 6,300
tons per month.
The County permanently closed the SHSL when it reached capacity in late 2019. In 2012, the County
commissioned a Hilo Landfill Feasibility Study, which determined that design and expansion of a landfill on
2019 Integrated Solid Waste Management Plan Update
County of Hawaiʻi
August 2020 9-3
the Hilo side of the island was not feasible, and
shipping to the WHSL was both feasible and cost
effective. In 2018, an Environmental Assessment
(EA) and subsequent Finding of No Significant
Impact (FONSI) was issued by the DEM on behalf
of the SHSL final closure and shipping to the
WHSL. The primary drivers for shipping to the
WHSL include:
•Limited capacity at the existing SHSL.
•Significant constraints to expanding the
existing SHSL (e.g., proximity to Hilo
International Airport).
•Significant constraints to establishing a
new landfill in East Hawaiʻi.
Thus, the landfill was closed, and residual waste is now hauled from the East Hawaiʻi waste stream to the
WHSL in Pu'uanahulu (Exhibit 9-2). A 30-year closure and monitoring program has been developed for the
SHSL. Plans include slope stabilization, installation of a gas ventilation system, and an improved stormwater
system (County of Hawaiʻi DEM 2017c).
To continue service to customers on the east side of the island upon the SHSL closure, the County
converted the East Hawaiʻi Regional Sort Station (EHRSS) in Hilo to not only accept recyclable and
reusable material, but also MSW. The County then trucks the residuals from the EHRSS to the WHSL.
Construction and demolition (C&D) debris, including grading and grubbing (G&G) materials (e.g., large
stumps) are not accepted as EHRSS, these materials must be hauled to WHSL.
9.3.2 West Hawaiʻi Sanitary Landfill
The WHSL is located southwest of Waikoloa at Pu`uanahulu in the North Kona District (Exhibit 9-2). The
County of Hawaiʻi owns the WHSL and County personnel operate the landfill. The WHSL is operated by
Waste Management of Hawaiʻi under a contract with the County.
Waste Management is currently responsible for
construction of new cells, environmental
monitoring, and closure and post-closure
activities.
The WHSL facility has been in operation since its
construction in 1993, and is located on
approximately 300 acres, of which 149 acres are
currently permitted for landfill activities. The
WHSL is a Resource Conservation and Recovery
Act (RCRA), Subtitle-D landfill 9 (40 CFR Section
257.2) as administered through Hawaii
Administrative Rules Chapter 58.1 (HAR 58.1). The
9 Non-hazardous solid waste is regulated under Subtitle D of RCRA. Regulations established under Subtitle D ban

landfill is lined with a geomembrane, and has an engineered leachate collection system. To comply with
the U.S. Environmental Protection Agency (EPA) Clean Air Act, a new landfill gas collection and recovery
system was installed in 2013.
The landfill accepted approximately 12,000 tons per month or 150,000 tons in FY 2018. The landfill has
23 cells currently permitted, of which 10 have been filled, and one (Cell 11) is active. Waste
Management is in the process of preparing Cell 12 for the next phase of disposal. The landfill property
also provides large areas for material recovery, disaster debris processing, and greenwaste. As reported
by the County in a 2019 Solid Waste Advisory Committee (SWAC) meeting, the WHSL has an estimated
100 years of life remaining at current recycling rates (Exhibit 9-3). If the community manages their waste
responsibly by reducing, reusing, and recycling; the life expectancy could exceed 100 years. As
forecasted in Chapter 2, the community would experience an average increased diversion rate of 8
percent through 2039 if approximately 50 percent of food waste is diverted when the proposed
compost facility is in operation during early part of the 10-year implementation period.
As described in Section 9.3.1, in 2012, the County commissioned a Hilo Landfill Feasibility Study, which
determined that the expansion of a landfill on the Hilo side of the island was unfeasible and shipping to
the WHSL was both feasible and cost effective.
In preparation of hauling waste to WHSL, the County Council adopted resolutions 310-17 and 311-17.
Resolution 310-17 authorizes the payment of a multi-year lease for five trailers and 311-17 authorizes
the payment of funds for five semi-tractors.
With the final closure of SHSL, the County is preparing a master plan focused on reconfiguring circulation,
scalehouse location, and other facilities in anticipation for additional residuals entering the landfill.
landfills, including design criteria, location restrictions, financial assurance, corrective action (cleanup), and closure
requirement. States play a lead role in implementing these regulations. (EPA 2018d)

2019 Integrated Solid Waste Management Plan Update
County of Hawaiʻi
August 2020 9-7
9.3.3 Landfill Disposal Fees
Under Ordinance No. 18-5, the County amended HCC 20 to increase the landfill disposal fees. Ordinance
No. 18-5 reads as follows:
The purpose of this ordinance is to increase disposal fees to cover costs incurred by the Solid
Waste Division of the Department of Environmental Management for services it provides to the
residents of and visitors to Hawai`i County. The County of Hawai`i’s Integrated Resources and
Solid Waste Management Plan complies with state mandates of waste reduction and provides a
path to provide solid waste disposal services for all, including the operation of all transfer
stations and recycling operations. The current plan requires capital improvements, new
equipment, maintenance of existing equipment, as well as improved service.
The County seeks a healthy economy that requires intelligent and efficient solid waste
management and disposal. Presently, the General Fund subsidy is substantial. Adoption of these
changes will reduce the Solid Waste Division’s dependence on the General Fund as well as
provide the groundwork for implementation of the updated plan.
In July 2019, landfill disposal fees increased to $110 per ton. Rates by vehicle size and volume, which
apply when weights cannot be obtained, were increased to $66 per vehicle for light trucks, $111 for
medium trucks and $198 for large trucks. For all other vehicles, disposal fees were retained as $36 per
cubic yard for compacted material, and $22 per cubic yard for non-compacted material. Special handling
fees (for handling asbestos) increased to $110 per truck load (or a fraction thereof). The fee schedule is
set to change in subsequent years, with specific rates established through 2022.
9.3.4 Evaluation of SHSL Capacity Replacement
Because the SHSL was near its permitted capacity and planned closure date, in 2003 the County began a
focused evaluation of potential options for future disposal of residual waste on the east side of the
island. One potential component to the overall solid waste management approach was to develop waste
reduction technology (WRT). Thus, in 2004, the County Council adopted Resolution 218-04 that supports
solid waste landfill diversion through waste reduction technology with procurement criteria that matches
Hawaiʻi County policies, needs and waste stream, and delineates next actions.
In 2006, the County initially evaluated five different waste reduction technologies: mass burn
incineration (mass burn), incineration using refuse derived fuel, aerobic composting, thermal
gasification, anaerobic digestion, and bio-refining. During the process, aerobic composting was found to
be unsuitable due to the potential for offensive odors; and bio-refining was found to be unproven and
likely not commercially viable technology. In addition, the evaluation concluded that anaerobic digestion
was not suitable “because it could only deal with a limited portion of the waste stream and did not yet
have a sufficiently viable commercial track record dealing with a municipal solid waste stream like that
of Hawaiʻi.” Thus, it was determined that either mass burn or thermal gasification, both WTE facilities,
were the most viable waste reduction technologies.
Between 2006 and 2014, the County issued several RFPs to vendors who could potentially design,
construct, and operate a mass burn or thermal gasification WTE facility. The County’s evaluation of
proposals during this time determined that a mass burn WTE facility was the most commercially and
technically viable option. Notably, a mass burn WTE facility was identified as having the potential to
reduce the volume of processed solid waste by 90 percent, reduce weight by 70 percent, and would
have air emissions below EPA standards.
In March 2008, Wheelabrator Technologies Incorporated (a wholly owned subsidiary of Waste
Management) was selected to develop a mass burn WTE project by the County. In response,
2019 Integrated Solid Waste Management Plan Update
County of Hawaiʻi
9-8 August 2020
Wheelabrator submitted a detailed cost proposal to design and construct a mass burn WTE facility to
replace the SHSL. After evaluating the Wheelabrator submittal, the County Council rejected the WTE
proposal largely because of concerns about higher than anticipated costs for the facility. In 2014, a third
RFP was issued for WTE facility proposals, and was withdrawn prior to the selection process.
As described in Chapter 4, in consideration of alternative methods for waste reduction to more
advanced technologies, the County contracted with a private contractor in 2016 to construct two
organics management sites: EHOF and WHOF. During FY 2016–17, a Notice to Proceed was approved for
the construction of these facilities through a private contractor and both facilities are now operational.
The County has also been engaged in developing a compost facility that not only handles green waste,
but also food waste and other compostables, to divert a larger volume of waste from the SHSL and
WHSL. In 2016, an RFP was issued for the construction of a Compost and Green Waste Processing
facility, and an Environmental Assessment (EA) was prepared that considered a proposed site at a
former rock quarry adjacent to the SHSL. The EA was ultimately withdrawn from consideration due to
concerns over the location and the potential impacts to the local community. Three new sites are under
consideration, with the composting facility slated for operation during early part of the 10-year
implementation period.
A chronology of County waste reduction technology procurement dating back to 1995 is provided in
Appendix E.
9.4 Issues and Concerns
Since the 2009 Plan, establishing a place for disposal of residuals from East Hawaiʻi when the existing
SHSL closes was a key residuals management issue. As described in Section 9.3.1, the County continues
to provide service to residents on the east side of the island regardless of SHSL closure. The County
converted the EHRSS in Hilo to not only accept recyclable and reusable material, but also MSW. The
County started hauling residuals from the EHRSS to the WHSL in 2019. The County no longer considers
hauling and landfilling residual waste from East Hawaiʻi an issue.
The County considers the potential for private sector development of residuals management facilities
without County involvement a policy issue. Section 9.4.1 considers how those facilities could affect flow
control and contractual obligations with landfill management companies that currently or may be under
contract to the County in the future.
Section 9.4.2 describes debris management in response to natural disasters.
Section 9.4.3 includes the long-term management of the closed Kailua-Kona and Waimea landfills.
In December 2018, the County recycling program revised the materials accepted due to changes in the
global recycling market. The County eliminated #5 plastics (e.g., yogurt containers, syrup bottles, margarine
tubs), plastic grocery bags, clam shell-type plastic (salad, bento, fruit, etc.) in the mixed recyclable bins
at the recycling and transfer stations. And again, in October of 2019, only cardboard, glass, and bi-metal
cans were collected for recycling – no plastic or paper. The HI-5 program remains intact.
With uncertainties in the global market, the County will need to consider other opportunities to dispose
of formerly recycled materials that end up in the waste stream, following a concerted effort of public
outreach to encourage residents to reduce and reuse these materials. Section 9.5 describes existing
recovery and treatment technologies and recovery and treatment options for the County that have the
potential to capture these formerly recycled materials.
2019 Integrated Solid Waste Management Plan Update
County of Hawaiʻi
August 2020 9-9
9.4.1 Private Facilities and Flow Control
Many government jurisdictions in the United States have flow control laws in effect to ensure that
materials flow to facilities in which they have significant capital investment and/or other interest. They
are common in jurisdictions with capital intensive WTE facilities.
In 1994, the U.S. Supreme Court ruled in the “Carbone decision 10” that a town’s flow control ordinance
discriminated against interstate commerce by favoring a privately owned local facility over out-of-state
private facilities. This decision put the legality of state and local government flow control laws affecting
public facilities in question. In April 2008, this issue was resolved when the Supreme Court ruled that
state and local government laws directing locally generated wastes to publicly owned waste facilities do
not discriminate against interstate commerce 11. This decision appears to establish the right of counties
to establish flow control ordinances directing locally-generated wastes to publicly-owned facilities.
In the County, a private waste processing firm, BioEnergy, has expressed interest in developing a
relatively large WTE recovery facility for processing the residuals it collects from businesses and
institutions. There are reasons to believe that this may not be a desirable for the County. A flow control
ordinance is one way that the County could ensure that residual materials flow to facilities that are
County owned, or operated under contract to the County.
A flow control ordinance protects the County against several risks associated with the private sector
developing facilities without explicit County approval. Some of those risks include:
•Because of the County’s relative isolation and small size, the potential barriers for local private
collection firms who wish to establish operations in the County are perhaps higher than on the
mainland. It is possible that a single private firm with a large national market share and its own
recovery facility could potentially keep collection costs higher than would otherwise exist in a
more competitive environment.
•Allowing a private firm to develop a large recovery facility reduces the County’s flexibility to
adopt waste reduction programs. County policy makers could be in the unenviable position of
having a large firm facing financial losses if the County were to require aggressive recycling or
bioconversion from businesses and institutions.
•The County would lose some degree of control and flexibility for choosing the recovery and
disposal technology that best meets the needs of the entire County.
At this time, the BioEnergy Hawaii still has issues it must resolve to secure land and permits. The County
continues to monitor the progress of this facility. If it appears that the facility will be developed, the
County will evaluate whether it is in the County’s best interests to allow the facility to proceed, or
whether it will establish a flow control ordinance to keep the flow of waste in the County system.
9.4.2 Natural Disaster Debris Management
The responsibility of natural disasters in the State begins at the county level. The State Civil Defense
System provides the operational infrastructure and procedures to meet the demands of natural
disasters but to be effective, input is necessary by each county. Hawaiʻi County Civil Defense is the local
agency that develops mitigation plans at the county level as coordinated with State Civil Defense. The

County regularly updates their Multi-Hazard Mitigation Plan, which is a requirement to be eligible for
Federal Emergency Management Funds.
9.4.3 Closed Landfills
9.4.3.1 Kailua-Kona
The Kailua-Kona Landfill was a municipal solid waste landfill that operated from the late 1970s until it was
closed in 1993. The landfill occupies approximately 20 acres and is located east of the Queen Ka'ahumanu
Highway approximately 3 miles north of Kailua-Kona in the North Kona District. Subsurface fires from
waste material have been documented at the landfill since 1991. During final closure of the landfill, a
final cover system of 30-mil polyvinyl chloride (PVC) geomembrane liner and 2 feet of cover soil were
installed in 1993. The cover has undergone damage from subsurface fires and intrusive investigations to
evaluate options for extinguishing the fires. Temperature and gas monitoring occur periodically as part of
the post-closure monitoring
Subsurface waste combustion continues to be a concern at the landfill. The County and its engineering
consultants are monitoring the current condition and extent of the subsurface fires and developing
options for subsurface fire suppression.
The once rural setting surrounding the landfill is being developed including a Hawaiʻi County Police
Department (HCPD) station, Kealakehe High School, West Hawaiʻi Civic Center, State Judiciary Complex,
and Kealakehe Recycling and Transfer Station. There are also plans for an affordable housing
neighborhood in the future. A regional park is in the draft NEPA environmental assessment phase.
Although there have been no recent complaints from neighbors since the County began proactively
managing the site, long-term management plans for the landfill are being evaluated by the County.
Management plans being considered include:
•Relocation of the Waste: The waste could be relocated to West Hawaiʻi Sanitary Landfill;
however, there are major health and safety concerns with digging into the landfill and moving
the waste. While this alternative is extremely expensive, it is considered clean closure and will
no longer require post-closure monitoring and maintenance, and the land can be used for
another purpose.
•Construction of a New Engineered Cap: Construction of an engineered cap could limit oxygen
infiltration into the waste mass and limit the current “chimney effect” that is occurring at the
landfill now. This alternative would not eliminate post-closure monitoring; however, it would
lessen maintenance costs.
•Implementation of a New Technology: The County is currently looking into technology being
used to extinguish subsurface coal fires. The technology works by injecting a foam mixture into
the waste mass. The foam consists of a biodegradable fire retardant and is injected using
nitrogen gas. The foam wets and cools the area of combustion. This is considered interim
mitigation.
9.4.3.2 Waimea
The Waimea Landfill is in Lālāmilo, in the South Kohala district, and consists of a single, unlined landfill
cell. The landfill was established in the late 1960s at a former quarry site, has an area of approximately
9.28 acres, and is located on land parcels owned by the State and the County. Landfilling activities
ceased during 1986, and the landfill was closed in 1987. A cover of several feet of fine soil was placed
over the top of the landfill. Records indicate that the quarry was originally excavated to an approximate
depth of 30 feet, and that approximately 35 feet of rubbish was landfilled at the site.
2019 Integrated Solid Waste Management Plan Update
County of Hawaiʻi
August 2020 9-11
Based on past investigations, filling and grading activities have been completed over portions of the
landfill and have extinguished subsurface fires by limiting the amount of influx of oxygen to the
subsurface of the landfill.
Currently, post-closure monitoring is being performed on a quarterly basis. The County and state are
currently in the discussion phase on the required word to “sunset” the post-closure monitoring
requirements. Additional cover material may be added to seal the landfill from the atmosphere to
prevent combustion and to provide stormwater control measures. Once the HDOH agrees with the plan,
the parcel can be used for other uses.
9.5 Material Recovery and Treatment Facilities Overview
This section provides 1) a background description of EPA’s waste management hierarchy and worldwide
trends regarding recovery and treatment of residuals (Section 9.5.1), 2) an overview of recovery and
treatment technologies (Section 9.5.2). Recovery and treatment options for the County are discussed in
Section 9.5.6.
9.5.1 Background
The EPA’s integrated waste management hierarchy (EPA 2018e) includes the following four
components, listed in order of preference:
1.Source reduction (or waste prevention), including reuse of products and on-site (or backyard)
composting of yard trimmings.
2.Recycling, including off-site (or community) composting.
3.Energy recovery.
4.Treatment and Disposal.
More broadly, there is an intermediate step to integrated waste management after the first “3Rs” of
source reduction, reuse, and recycling (including bioconversion), the “4th R” that can be referred to as
recovery or treatment. For the foreseeable future, after source separation, reuse, recycling, and
2019 Integrated Solid Waste Management Plan Update
County of Hawaiʻi
9-12 August 2020
bioconversion are completed, there will be residual materials that must be managed. Currently, that
residual material is disposed of in County landfills.
Throughout the world, there is a trend to implement additional treatment of these residual materials
prior to landfill disposal using processes such as waste to energy (WTE) or mechanical-biological
treatment (MBT). Locally, Honolulu’s WTE facility reduces approximately 90 percent of its waste volume
and has saved approximately 500 acres of landfill space since its construction (SWANA 2014). Treatment
consists of applying some combination of mechanical, biological, chemical, or thermal processes to the
material prior to landfill disposal to recover energy and additional useful materials, and to remove
organics from the residuals that are sent to landfill. The objectives and benefits of recovery and
treatment include the following:
•Recovering additional materials for recycling that remain in discarded materials after the source
reduction, reuse, and recycling.
•Recovering the inherent energy remaining in discarded materials after source reduction, reuse,
and recycling.
•Stabilizing the organic fraction of residuals to minimize greenhouse gas emissions and other air
emissions from organics that remain after source reduction, reuse, and recycling.
•Reducing the volume and toxicity of materials sent to landfill.
•Preserving land and extending the lifespan of existing landfills.
Recovery and treatment facilities (often more narrowly referred to as conversion, emerging, or
alternative technologies) are in the planning stages in many United States jurisdictions. A recent
assessment of alternative technologies is included in Exhibit 9-4 below.

Outside the United States, many other countries are implementing recovery and treatment technologies
prior to landfill disposal. The European Union initiated a circle economy plan wherein they aim to
achieve 65 percent recycling of municipal waste and to restrict MSW landfilling to 10 percent by 2030
(European Parliament 2017). Implementing technologies to meet these requirements is projected to
2019 Integrated Solid Waste Management Plan Update
County of Hawaiʻi
August 2020 9-13
significantly reduce greenhouse gas emissions from landfilling in the European Union. Recovery through
thermal means is widespread in Japan and other Asian countries, and new recovery/treatment facilities
are currently being developed in Canada, Australia, and New Zealand.
9.5.2 Overview of Recovery and Treatment Technologies
There is a tremendous variety of possible recovery and treatment options for municipal solid waste
currently in operation or under development. They range from options with a long, successful track
record in the United States and elsewhere (such as mass burn WTE facilities) to potentially promising
new technologies in various stages of testing and development (such as the flash carbonization process
being developed at the University of Hawaiʻi, Mānoa). There are various ways of grouping recovery and
treatment technologies for MSW; however, this Plan update classifies them into the following three
groupings:
•Thermal.
•Mechanical-Biological Treatment.
•Other.
The “other” technologies refer to a wide variety of different processes (and process elements) that are
in various stages of development such as thermal depolymerization, hydrolysis, autoclave, and flash
carbonization. At this time, there are no commercial-scale facilities processing MSW using these
technologies in the United States and very few that are currently operated at a commercial scale
elsewhere in the world. Thus, while these technologies could be investigated further, they are not
assessed further in this Plan update.
9.5.2.1 Thermal Technologies
For the purposes of this discussion, thermal technologies
have been grouped into the following five main categories:
mass-burn, refuse-derived-fuel (RDF), gasification, pyrolysis,
and plasma arc. A summary of each type of technology
follows.
Mass-burn. These facilities are by far the most common
recovery technology currently utilized in the United States
and around the world. In this system, residual materials are
loaded from a pit into a furnace with little or no pre-
processing. The materials are combusted, and the heat is
used to produce electricity and/or steam. In fact, European countries such as Sweden and Denmark
have the capacity to treat 100 percent or more of their MSW through incineration (European Parliament
2017). In the United States, 70 mass-burn facilities utilize 14 percent of waste destined for landfilling
(Seltenrich 2018). As discussed above, the County conducted a procurement process for a waste
reduction technology to replace the SHSL and selected mass-burn WTE technology. This technology was
selected mainly because of its long, successful, track record for processing MSW.
The main advantages of this technology are its proven and reliable operating history, the ability to
expand, and the environmental benefits that result when WTE output are used to displace power that
would otherwise be generated by fuels such as oil or coal.
A main disadvantage of this technology is that the upfront money necessary to construct a mass burn
WTE facility is considerable, and it may take several years before the economic benefits are realized.
2019 Integrated Solid Waste Management Plan Update
County of Hawaiʻi
9-14 August 2020
According to the EPA, a small new plant typically requires at least 100 million dollars to construct
(EPA 2017b).
Refuse-Derived-Fuel. Reduced-Derived Fuel (RDF) facilities
include front-end pre-processing to recover materials and
produce a fuel that is sent to a combustion unit to generate
electricity and/or steam. The H-Power facility in Honolulu is
a good example of this type of technology.
Compared to mass burn WTE facilities, RDF facilities can
result in increased recovery of recyclable materials. On the
other hand, the pre-processing requirements add
complexity to the system and there are more types of
materials that cannot be burned in an RDF plant than in a
WTE facility. In part because of these distinctions, RDF
plants are somewhat less popular than WTE facilities.
However, the cost, reliability, and performance of this technology is relatively like that of mass-burn facilities.
Gasification. Gasification facilities differ from mass-burn and
RDF plants because they focus on creating a synthetic gas
that can be used to produce energy, and the gasification
process uses very limited amounts of oxygen. Materials are
first shredded and or sorted to ensure consistent sizing, and
then are fed into a gasification chamber. The gasification
process heats materials to very high temperatures (1,650ºF
to 2,200ºF) where chemical reactions take place to form a
synthetic gas from the organic fraction of the materials and a
glass-like slag from the inorganic fraction. Some systems
reclaim recyclables prior to gasification, or control the
chemical process in order to produce usable products from
the inorganic fraction after the gasification step. After
cleaning, the gas can be burned directly in an internal
combustion engine or turbine, or used to create a synthetic
fuel. The gas is usually used to generate electricity or as a
vehicle fuel. The process used to create the gas typically uses only enough oxygen to produce the
desired temperatures.
This technology has some key advantages compared to typical WTE facilities including:
•A variety of process features provide opportunities for fewer air emissions.
•The syngas created is potentially more efficient than direct combustion of MSW because it can
be combusted at higher temperatures or even in fuel cells.
•The technology appears to scale down to smaller sizes more efficiently than WTE facilities,
potentially making it more applicable to smaller communities working toward a goal of zero
waste.
Some disadvantages of this technology include:
•Service intervals are typically on the order of a few months for the plants, requiring frequent
plant shutdowns to maintain and clean the reactor.
•Lack of successful commercial demonstration in the United States (few examples worldwide)
and related uncertainties surrounding the cost and long-term effectiveness of the technology.
2019 Integrated Solid Waste Management Plan Update
County of Hawaiʻi
August 2020 9-15
•Environmental permitting regulations are unclear or nonexistent.
•Public education is needed to overcome negative perceptions of thermal technologies.
Pyrolysis. Pyrolysis refers to the chemical decomposition of a substance by heating in the absence of
oxygen. Pyrolysis typically occurs at temperatures ranging
from 750ºF to 1,650ºF. The composition of the pyrolytic
product is changed by the temperature, speed of process,
and rate of heat transfer. Lower pyrolysis temperatures
usually produce more liquid products and higher
temperatures produce more gases. Pyrolysis is used
frequently in the chemical industry, for example, to produce
charcoal, activated carbon, methanol and other chemicals
from wood, and to produce coke from coal. For MSW, pre-
processing steps are required that include separation and
screening to remove contaminants, shredding to reduce
particle size, magnetic separation to remove conductors,
classifying to refine, drying to increase the calorific value, and (in some systems) pelletizing to obtain
homogeneity.
The products resulting from the pyrolysis process are a synthetic gas and/or liquid and a char. The gas is
burned in a secondary combustion chamber, then is typically passed through a boiler for heat recovery.
Although some oxygen may be used for combustion of the gas to destroy organics, the combustion
takes place in a gaseous phase requiring much less oxygen than incineration. This results in the
formation of much less nitrous oxide and soot from the power generation process.
There were many attempts in the United States to scale up this technology from pilot scale
demonstration plants during the 1970s and 1980s, and none of the plants were able to overcome
challenges associated with maintaining a sealed chamber to keep air out, adjusting the process to match
the variability of the MSW inputs, and competition with landfills and WTE facilities. Recently, interest in
this technology has increased; however, it remains to be seen if it will become commercially viable in
the United States.
The advantages and disadvantages cited above for gasification also generally apply to pyrolysis, with
various advantages and disadvantages associated with specific processes and vendors.
Plasma Arc. Plasma arc technology, developed for use in the metals
industry in the late 1900s, uses intense heat (over 7,000ºF) to break
down feedstocks into elemental byproducts. Plasma is a collection of
free-moving electrons and ions that is typically formed by applying a
large voltage across a gas volume at reduced or atmospheric
pressures.
MSW is fed through this gas, changing the organic fraction into
elemental compounds such as hydrogen, oxygen and carbon, and the
inorganic fraction into a glass-like vitrified mass that is claimed to be
highly resistant to leaching.
An estimated 22 plasma arc waste processing facilities exist around
the world, notably in Japan, France, and by the United States Navy
(Circeo 2009).
The advantages and disadvantages of this technology are like those of pyrolysis and gasification. One
additional advantage of this system compared to the others is the more complete breakdown of
2019 Integrated Solid Waste Management Plan Update
County of Hawaiʻi
9-16 August 2020
materials has the potential to result in the lowest possible percent of residuals sent to landfill. One
drawback of the technology is the high electric power requirements for the torches, which may make it
more difficult to obtain net energy benefits from this technology. To address this, some developers are
using the plasma arc after an initial gasification step.
9.5.2.2 Mechanical-Biological Treatment
Mechanical-Biological Treatment (MBT) describes the integration of processes normally found in
material recycling facilities (MRFs), RDF (refuse-derived-fuel), plants, and composting plants. A key
feature of the process is using the activity of microorganisms to create a stabilized output. This can be
accomplished either in the presence of oxygen (aerobically; that is, composting) or in the absence of
oxygen (anaerobic digestion). The output of the process is typically either stabilized organic matter
(compost or landfill cover), biogas (for fuel), or drying (for producing a refuse-derived-fuel).
Like thermal technologies, there are many different MBT processes, systems, and vendors. In 2017,
Europe had an estimated 570 active MBT facilities in 2017 resulting in the diversion of 55 million tons of
residual waste (O’Brien 2017). The operation of these facilities can further zero waste endeavors. Mixed
municipal solid waste (MMSW) composting is a type of MBT facility that has been tried by various
jurisdictions in the United States.
While MMSW composting is a type of MBT, these “first generation” plants developed in the 1980s and
1990s usually consisted of just an initial shredding and/or biological drum treatment and aerobic
composting. There are numerous examples of failed MMSW composting operations resulting from high
costs, ongoing equipment breakdowns, odor concerns, and/or an inability to market the compost end-
products. Many of the new European MBT plants are more sophisticated than first generation MMSW
composting plants, and United States composters are continually modifying and optimizing systems;
however, there are challenges that must still be overcome. Examples of challenges with this technology
include the Pine Top, Arizona, MBT plant, which was converted from accepting MSW to accepting only
source separated organics, because of equipment maintenance issues and the challenge of finding
markets for the compost it produced. The largest MBT plant in North America, in Edmonton, Alberta,
has faced challenges related to equipment failures and maintenance, and the City is considering
modifications to its current process to produce an RDF product, or other alternatives to improve the
economics of the plant. However, the feasibility of this option is improving, in 2017 the first functioning
MBT facility in the United States was opened in West Virginia. The end-product will be used as a clean-
burning alternative to coal (Recycling Production News 2016).
Recent experience with European MBT plants has resulted in many similar technical problems initially,
with low throughput capacity caused by machine overload or breakdown and higher operational costs
than expected due to high maintenance and service requirements. There have also been challenges
during mechanical separation. Many of the problems encountered at European plants have been solved,
and nearly all of the European facilities are running at their expected capacities, and in some facilities,
this has resulted in significantly higher than anticipated operation costs. One common weak point at
MBT facilities is the final biological treatment process, which is often designed like a composting
process. Managing odors and meeting material specifications is an ongoing process that requires
constant attention.
All MBT processes involve waste input and control, mechanical preparation, biological and/or thermal
treatment, and product conditioning. Waste input and control normally consists of manually removing
oversized and hazardous materials. Mechanical processing can include minimal separation or shredding,
or sophisticated sorting of the inbound waste into biodegradable material, recyclables, and contaminant
streams. Sorting is usually done with dry processes, and it can also involve wet processes, such as
2019 Integrated Solid Waste Management Plan Update
County of Hawaiʻi
August 2020 9-17
flotation and hydro-pulping. Depending on the quality and market demand, the recyclables are typically
sold. Paper fibers, textiles, rubber, plastics, and residual organics can be used as RDF.
The biological stage of the MBT process can either be aerobic composting or anaerobic digestion. The
outputs of this process can be either a synthetic gas, RDF, or compost. The quality of the compost will
depend on the specific process used and the ability to separate metals, plastics, glass fragments, and
toxic materials from the organic fraction. However, in general, the compost produced from an MBT
process is of lower quality than compost produced from source-separated organic material such as
green waste or food waste. Some plants produce multiple types of compost and target products for
specific applications such as agricultural use, site remediation, or landfill cover. Some processes result in
large quantities of residuals (up to 50 percent) that must be landfilled.
Like the thermal recovery options, there are many different processes and systems used in MBT plants.
For the purposes of this Plan update, MBT systems are classified into three groups:
•Biological treatment with RDF for combustion.
•Biological treatment with composting.
•Anaerobic digestion.
A brief overview of each type of MBT system follows.
Biological treatment with RDF for combustion. A popular approach in Europe is to do relatively little up-
front sorting, and use the heat released from aerobic breakdown of organics to dry the materials. Metals
and inert materials are then removed, and paper fibers and plastics are made into RDF. The value of this
fuel is relatively high and can be used as a substitute for fossil fuels in a wide range of applications,
including power stations and vehicle fuel. The process also produces composted material that can be
landfilled. Through this process, a 65 to 90 percent diversion rate may be achieved (Arsova 2015).
Biological treatment with composting. In this process, relatively little mechanical pre-processing is done
upfront and materials are fed into a long, rotating drum (made by companies like Bedminster and Dano)
where the MSW is processed for 1 to 4 days. The combination of the mechanical rotation and the
beginning of the biological degradation of the organic material allow a reduction of the organic fraction
size and good mechanical separation of the organics from physical contaminants. At the end of the
process, the organics are sent to composting. The inorganic fraction is either sent directly to a landfill or
sorted further to recover recyclables depending on whether markets exist for the sorted materials. This
process achieves a 50 percent diversion rate and does not produce biogas, rendering energy recovery
inplausible (Arsova 2015).
Anaerobic digestion. Anaerobic digestion uses anaerobic
bacteria to break down material without oxygen. This
technology is well established for treating outputs from
wastewater treatment plants, dairy farms, and other
sources of relatively homogenous organic material. It is
now beginning to be applied to source-separated organics
and MSW.
To treat MSW using anaerobic digestion, organics must be
separated from inorganics and prepared into a slurry
appropriate for the digesters. This separation process has
proved to be challenging at many facilities processing MSW and organics. Various technologies exist for
the initial separation process that use water, screens, magnets, separators, and shredders in various
combinations.
2019 Integrated Solid Waste Management Plan Update
County of Hawaiʻi
9-18 August 2020
During the digestion process, about two-thirds of the biodegradable organic matter is transformed into
a biogas composed mainly of methane and carbon dioxide. The remaining one-third comes out of the
process as a digestate that must be treated using an aerobic curing phase (composting) to stabilize it
prior to landfilling. Anaerobic digestion systems for MSW treatment are limited in the United States,
which may be due in part to the relatively low cost of fossil fuels in the United States in comparison to
Europe, where anaerobic digestion technology is more widely used due to high fossil fuel prices, high
tipping fees, and government incentives (Edwards et al. 2016). [European Union Directive requires union
members to reduce landfilled organics by 65 percent by 2020 (Rogoff et al. 2014).]
According to a study performed in 2014, many factors come into play regarding the viability of an anaerobic
digestion system as a large-scale MSW disposal option in the United States, including the need for:
•Significant centralized source of high-quality organic waste.
•High energy costs (higher revenue for facility).
•Limited land for siting a compost facility.
•Lack of conventional WTE facilities.
•Markets for residual (compost) or an outright ban on organics in landfills (Rogoff et al. 2014).
It has also been reported that aerobic composting MBT systems (e.g., biological treatment with RDF for
combustion) are likely to cost 30 percent less than anaerobic digestion treatment systems for both low
and high capacity systems (Arsova 2015). Additional costs may include landfilling of unmarketable
residual waste, daily operation, and maintenance fees.
In 2017, the EPA developed a co-digestion economic analysis tool “CoEAT” that helps users (e.g., municipal
managers) quantify the cost to benefit analysis of processing organics including parameters such as:
•Fixed and recurring costs.
•Solid waste diversion savings.
•Capital investments.
•Biogas production and energy savings.
In recognizing the need to better understand anaerobic digestion facilities, the EPA is also conducting a
study that collects data from operators of anaerobic digestion facilities for 3 years (data collection began
in 2015). To date, they have published survey results from three types of systems: stand-alone food
waste digesters (multi-source and industry-dedicated), on-farm digesters that co-digest food waste, and
digesters at water resource recovery facilities that co-digest food waste. The survey establishes the
number of anaerobic facilities processing in the United States and their locations, and their processing
amounts and available capacity. Other information gathered includes non-food waste processed,
feedstock types and sources, tipping fees, pre-processing and de-packaging processes, operational
specification, and biogas production. At the time of the survey, none of the three systems surveyed is in
operation in the State of Hawaiʻi. The final reporting of EPA’s anaerobic digestion study findings is
expected to conclude in 2019 or 2020 (EPA 2018f).
9.6 Recovery and Treatment Options for the County of Hawaiʻi
It is important to note than no currently known recovery or treatment technology will remove
100 percent of residuals from the municipal waste stream: thus, for the foreseeable future, landfill
capacity will be required for residuals generated in the County. With the onset of SHSL closure, the
County has three primary landfill disposal options: trucking East Hawaiʻi residuals to the WHSL at
Pu`uanahulu, or barging residuals to another Hawaiian island, or to the mainland. As previously
2019 Integrated Solid Waste Management Plan Update
County of Hawaiʻi
August 2020 9-19
described, the County began trucking MSW to the WHSL in 2019. A recovery and treatment facility could
play an important role in decreasing the volume of solid waste landfilled at the WHSL.
A new recovery and treatment facility will likely cost considerably more than the cost of trucking East
Hawaiʻi waste to the WHSL. Thus, a central question to evaluate when assessing whether to develop a
recovery and treatment option is:
Do the environmental benefits of these facilities outweigh their additional cost?
The following recovery and treatment options for consideration are discussed below.
R-1 Study Recovery and Treatment Technology
R-2 WTE Facility for all County Residuals; Ash and Bypass Materials to WHSL
R-3 One or More Modular WTE Facilities in Rural Areas; Ash and Bypass Waste to WHSL
R-4 Develop MBT Facilities at the SHSL and/or WHSL Sites
9.6.1.1 R-1 No Action; Study Recovery and Treatment Technology
In this option, the County would take no immediate action toward developing a new recovery or
treatment project. The County would instead assess the change in volume of residuals after the
proposed organic composting facility in Hilo is fully operational (slated to accept food waste and other
compostable materials beyond yard waste during early part of the 10-year implementation period).
Further, the County would engage in a dialogue with other Hawaiʻi counties about the potential for joint
solutions. For example, the County may consider shipping materials that were formerly recyclable
(e.g., #5 plastics) to the H-Power facility in Honolulu if determined economically cost effective (i.e., cost
savings, cost neutral) and through close coordination and negotiations with the City and County of
Honolulu. If deemed necessary, these efforts could be followed by a study that emphasizes the
identification of appropriate recovery and treatment technology sizing options for the County.
Advantages Disadvantages
Reduces the risk of unsuitable sizing of
recovery and treatment technology
Reduces the risks associated with being at the
leading edge of a new technology, such as
technology failure or unexpected cost
increases.
Continued reliance on landfilling as the County’s singular
residuals management for a few more years.
Cost Considerations. The cost would be nominal since the County would only investigate recovery and
treatment options if it is determined that the proposed compost facility and/or the possibility of
shipping waste to the H-Power Plant in Honolulu would not markedly increase the quantity of waste
diverted from WHSL.
9.6.1.2 R-2 WTE Facility for all County Residuals; Ash and Bypass Materials to WHSL
In this option, a new procurement would be conducted by the County seeking to develop a large WTE
facility that could accept residuals from the entire County. This would require a siting study to
determine where it would be located; typically, the closer such a plant is located to the primary
population and employment centers in West Hawaiʻi, the lower the associated operating costs.
2019 Integrated Solid Waste Management Plan Update
County of Hawaiʻi
9-20 August 2020
Advantages Disadvantages
Reliable, long-term recovery technology Considerably higher cost than landfill
Environmental benefits, including reduced greenhouse gas
emissions from displacing electricity from oil-fired
combustion units and additional recycling of metals
The facility would provide a disincentive for
aggressive additional waste reduction and
recycling, which goes against zero waste principles
Preservation of land, and landfill capacity Emissions and costs associated with trucking
rubbish to the plant
Reduced potential for water quality impacts from landfilling
unstabilized residuals, and reduced volatile organic
compound emissions
WTE facilities burn waste resources that can be
recycled or composted in a well-integrated system
Economies of scale of a larger facility would result in lower
costs than a smaller facility
Cost Considerations. The cost of large WTE would probably be less than smaller facilities due to
economies of scale. This cost savings, however, could potentially be offset by the cost of transferring
and trucking waste materials to the facility.
9.6.1.3 R-3 Modular Incinerators in Rural Areas; Ash and Bypass Waste to WHSL
Much of the County is rural in character, and the County incurs
considerable cost transporting residuals from its recycling and transfer
stations to the landfill. One option to consider would be to procure and
develop one or more small, modular incinerators in rural areas. This
would dramatically reduce transportation costs and has the potential to
be a cost-effective recovery system that could be located at one or
more of the County recycling and transfer stations.
While there are relatively few such units used to process MSW on the
mainland, there are more than 1,000 modular incinerators serving rural
areas, military facilities, and hospitals around the world. These facilities
can be good recovery systems for smaller, remote locations. These
systems generally cost less in installed cost per ton-day than larger,
mass burn WTE facilities; however, they do not have the longevity of those facilities and can cost more
to operate on a per-ton basis.
In this type of system, MSW is loaded into a surge chamber using a rubber tire bucket loader. The door
that seals the lower chamber is then opened and waste is injected into the combustion chamber.
Additional waste can be loaded into the surge chamber after the lower chamber door is closed. It is
assumed that the unloading floor would accommodate two unloading stalls plus some room for
separated bulky waste that would need to be transferred separately in transfer trailers or drop boxes to
a County landfill.
The lower chamber operates at about 1,850°F, while the upper chamber operates at about 1,450°F for
reducing air pollution emissions. There is no grate in this unit. Air is applied at a rate that is less than
necessary to complete combustion resulting in essentially a gasification or pyrolysis process. The partial
combustion products pass into an afterburning secondary chamber that will ensure successful burn out
of particulate combustion gases. Air is supplied by outside blowers to provide correct combustion for a
given application to meet local emission standards. Controlling the lower chamber gas velocity is
important in this process to maintain a quiet combustion area. Ash is removed using a roll-off box that
when filled can be transported to the landfill.

These systems can be used to recover steam and/or generate electricity. Successful electricity
generation depends on access to existing electric system infrastructure and a power utility that is a
willing partner.
For the purposes of sizing and developing cost estimates, this option assumes the following:
•The facility would be located at the Wai`ōhinu Recycling and Transfer Station, which would
accept waste from other surrounding recycling and transfer stations.
•The waste stream assessment forecast in 2009 estimated that 18 tons would go to the facility on
an average day (assuming the recycling rate at that time). Thus, a 20-ton-per-day unit would
provide adequate capacity for peak flows; yet, it would not be oversized if significantly more
waste is reduced or recycled.
•The facility would be staffed by two to three County employees each day. A front-end loader
would be needed to separate bulky materials and load residuals into the unit.
•Improvements to the recycling and transfer station would be required including a small
(10,000 square feet) building with a tip floor and a bulky waste load out chute. This could be
integrated with planned improvements to the Wai`ōhinu Recycling and Transfer Station.
•About 10 percent of the residuals received would be bulky wastes not appropriate for
incineration—these would be transferred to the WHSL.
•Thirty to 35 percent of the incoming material by weight would need to be transported to the
WHSL as ash.
Advantages Disadvantages
Reduction of about 20 percent of total system transfer
truck miles and reduced landfilling of organics would
result in less air pollution and greenhouse gas emissions
While the system should be able to meet EPA air
quality requirements, some air pollutants would
result from the incineration process
Potential for additional metal recovery for recycling after
combustion
Likely community opposition
Capital and operating costs are uncertain at this
stage–would need an RFP process to confirm
A new technology and system would require
additional training and skills for County staff
Cost Considerations. It is estimated that this option will have a range in cost and will be highly
influenced by site specific considerations, particularly installation of the unit in a relatively remote area.
Additional research and/or RFP process would be required to refine this estimate much further.
This estimate includes capital and operating costs minus transportation cost savings. In 2020, it is
estimated that this facility would eliminate about 20 percent of the miles currently driven by the
County’s recycling and transfer station trailer fleet.
Costs associated with landfilling will be substantially decreased.
It is assumed that the project would be combined with a reconstruction of the Wai`ōhinu Recycling and
Transfer Station.
It is possible that electricity sales could be profitable for this facility, and considering its remote location,
it would be safe to assume no cost for the equipment necessary to generate electricity and no revenues
from energy sales.
2019 Integrated Solid Waste Management Plan Update
County of Hawaiʻi
9-22 August 2020
9.6.1.4 R-4 Develop Mechanical Biological Treatment (MBT) Facilities at the WHSL Site
As discussed above, there are a handful of Mechanical Biological Treatment (MBT) facilities operating in
the United States and numerous facilities operating elsewhere in the world. While MBT facilities are not
as “proven” as WTE or RDF facilities, there is enough operating history for the County to consider
developing one or more MBT facilities. It would be prudent for the County to consider initially
developing a facility for East Hawaiʻi because there will be fewer residuals received at the EHRSS
compared to WHSL and these materials would not have to be transported.
This option would require additional study, and an RFP process. Through that process, the County could
decide on the desired outputs from the process (RDF, biogas, compost), assess markets for recovered
materials, and evaluate the implications for landfill operating practices. It is possible that the facility
could be developed at the SHSL site, potentially making use of the reload facility in some capacity.
Advantages Disadvantages
Reduced greenhouse gas emissions Much higher cost than landfilling
Reduced potential for water and air pollution from
landfilling
Higher risk of system failure leading to higher than
anticipated costs compared to WTE or landfill disposal
options
Additional recovery of materials not reused or recycled
prior to reaching the plant
Systems have many moving parts and will require
specialized operating expertise, sound preventive
maintenance, and vigilant on-going odor management
practices
Beneficial use of materials not otherwise recovered
such as electricity, vehicle fuels, compost, landfill cover
Preservation of current landfill capacity and reduced
need for additional land for landfill activities
Cost Considerations. This option would have a wide range in costs. These costs would be influenced by
multiple different types of MBT systems currently available, wide ranges in the reported cost of these
systems, and challenges in translating those costs to the County. The results of a conceptual design of
two MBT facilities (one for East Hawaiʻi and one for West Hawaiʻi) would also have an associated cost. In
general, lower cost systems:
•Achieve lower material recovery.
•Send more residual materials to landfills.
•Are in rural areas so that odor controls are less critical.
•Produce residual materials that must be landfilled.
9.7 Landfill Disposal Options
The County’s progress toward waste reduction and any decision on whether to implement a recovery or
treatment option will not eliminate the need for landfill capacity for the foreseeable future. At planned
recycling rates, and taking into account the 2019 closure of SHSL, WHSL has approximately 100 years of
remaining life (2119). As more materials are reused or recycled, or if a recovery facility is developed, the
capacity of WHSL will be extended.
The following two landfill disposal options address both short-term and long-term considerations.
2019 Integrated Solid Waste Management Plan Update
County of Hawaiʻi
August 2020 9-23
9.7.1 Improve Existing Infrastructure and Operations
Because the WHSL receives East Hawaiʻi’s waste with the closure of the SHSL, another option includes
improving the operation and monitoring of WHSL. The public has various concerns related to
environmental degradation, odor, and impacts to the tourism industry; some of these issues can be
resolved through the implementation of innovative technology at the landfill. Potential improvements
are described below.
9.7.1.1 Update Infrastructure at the WHSL and EHRSS
The County will continue to conduct periodic evaluations as needed to improve facility operations and
efficiencies at WHSL and EHRSS in response to changes in flow patterns and increased volume. Activities
could include:
•Integrate compaction into the floor space of the EHRSS.
•Reconfigure circulation, scalehouse location, and other facilities at WHSL to handle the
additional residuals.
Cost Considerations. The County SWD already has funding allocated via the County Capital
Improvements Program for EHRSS facility upgrades.
9.7.1.2 Landfill Gas to Energy
Once landfilled, waste undergoes anaerobic digestion, wherein microorganisms break down organic matter
and release products such as carbon dioxide and methane (Exhibit 9-5). Landfills constituted 14.1 percent
of United States methane emissions in 2016 (EPA 2018g). Methane is approximately 28 to 37 times more
potent as a greenhouse gas than carbon dioxide (EPA 2017a). This gas may be collected, compressed, and
isolated (Silva dos Santos et al. 2018). Once isolated, methane may be used to run gas turbines and fuel
cells as an energy source (California Energy Commission 2018) or as compressed gas for services vehicles.
Exhibit 9-5. Landfill Gas to Energy Schematic
Source: EPA (2018f)
2019 Integrated Solid Waste Management Plan Update
County of Hawaiʻi
9-24 August 2020
The collection and conversion of methane not only will mitigate the greenhouse gas emissions, it will
also decrease odors from the landfill. The volume of methane may be tripled through the addition of
water to a landfill through an acceleration of the decomposition process (FirmaTek 2017), leading to
increased energy generation as well. The County already collects landfill gas at WHSL. Instead of
combusting the methane in a flare, this gas could be converted to energy, an effective, environmentally
friendly means of recovering the resource.
Cost Considerations. As the landfill owner, the County could receive revenue from the sale of electricity
generated from the landfill gas and could possibly be eligible for revenue from renewable energy and
tax credits and other incentives. These potential revenue sources could help offset capital costs.
9.7.1.3 Odor Control
In addition to landfill gas, odors from landfills are often generated from leachate. Leachate contains
relatively high concentrations of organic matter, sulfur-based compounds, heavy metals, and
chlorinated salts (Berihum 2017) resulting in odorous compounds. Because of its generally low pH,
leachate often contains high concentrations of acidic odor-causing compounds (Goldstein 2005 et al.).
Although odors are not an issue at this time, if they are in the future due to changed surrounding land
uses or increased volume of residuals, landfill odors may be managed in various forms:
•Water-Soluble Misting: Liquid or solid waste can be treated through the application of mists
containing antibacterial disinfecting compounds (Berihum 2017). For instance, Odor
Management Industries has developed a product called Ecosorb that uses a non-hazardous
mixture of plant-based material, surfactant, and water to absorb odor-causing molecules and
deodorize the surrounding air (OMI Industries 2017).
•Enzyme Protein Misting: When odor molecules contact enzyme/protein solutions, a chemical
reaction occurs, changing the odor-causing chemical’s molecular structure and eliminating the
odor-causing scent (Peter 2014). These enzymes may also be applied through a mister.
•Lime: The application of lime to leachate, animal waste, and sludge solidifies waste and can
reduce odor from acidic compounds (Goldstein 2005 et al.).
Cost Considerations. Cost of alternative odor control mechanisms varies depending on the desired
application, and would be assessed if there is a future need–the current system of combusting methane
is effective in reducing odors at this time.
9.7.2 Construct a Construction and Demolition Landfill with a Sorting and
Reuse Area
As defined in Hawaiʻi Administrative Rules 11-58.01-03: "Construction and demolition waste" means
solid waste, largely inert waste, resulting from the demolition or razing of buildings, of roads, or other
structures, such as concrete, rock, brick, bituminous concrete, wood, and masonry, composition roofing
and roofing paper, steel, plaster, and minor amounts of other metals, such as copper. Construction and
demolition waste do not include cleanup materials contaminated with hazardous substances, friable
asbestos, waste paints, solvents, sealers, adhesives, or similar materials.
C&D waste commonly contains inert materials including cement, concrete, bricks, wood, and ceramics.
These materials may be recycled and used as aggregates for embankments, layers of foundation, road
foundations, and asphalt (Mei et al. 2014). Materials of significant market value, such as metals, may be
sold to specialized recyclers while other materials such as aggregates and wood may be ground at the
C&D facility and sold or used in a beneficial manner (Harler 2014). Developing a specialized C&D landfill
2019 Integrated Solid Waste Management Plan Update
County of Hawaiʻi
August 2020 9-25
with a sorting and reuse area would provide an opportunity to divert materials that would otherwise be
landfilled.
This section discusses existing C&D material handling facilities in the State of Hawaiʻi, mechanisms to
increase diversion, management options, and benefits.
9.7.2.1 Existing C&D Material Handling Facilities–State of Hawaiʻi
The State of Hawaiʻi currently has one privately owned C&D landfill located on O'ahu. The C&D landfill
and recycling facility is owned and operated by PVT Land Company. According to the company website,
at full capacity, the facility processes up to 1,775 tons and diverts up to 1,420 tons of debris daily for
reuse and recycling instead of landfilling the material. Of the 1,755 tons of processed material,
approximately 42 tons is metal, 900 tons is feedstock for energy production, and 840 tons includes rock,
concrete, and dirt. The remaining unrecyclable material (200 tons) is landfilled. The feedstock is
stockpiled for eventual use in a gasification facility. At the time of this Plan, PVT Land Company is
preparing to relocate their operations to 179 undeveloped acres across the road from the existing
operations. The new facility would be expanded to include two materials recovery and processing lines
as well as the installation of an enclosed gasification unit and photovoltaic panels to power operations.
The project is currently in the planning and environmental approval phase, and will require a Special Use
Permit because the proposed activity is not consistent with the zoning of the site (State Land Use
Agricultural District) (PVT Land Company 2019).
Although not a C&D landfill, Hawaiʻi Materials Recycling in Maui County accepts concrete, concrete
block, asphalt, rock, dirt, and sand. The facility is sited so that it can use reclaimed water from the
island’s wastewater treatment plant.
9.7.2.2 Diversion Mechanisms
For an effective program, the County would need to consider methods to maximize the diversion rates
of C&D waste. These methods are discussed in Chapter 3, Section 3.5.3. The options include building
permit requirements, establishing mandates to prevent certain materials from disposal at the landfill, or
setting specific recycling rates for C&D. As discussed in Chapter 4, Section 4.5.1, the County could
explore opportunities to develop an Eco-Industrial Park that includes clusters of complementary
businesses (e.g., organics, building deconstruction, salvage, reuse, and repair) through favorable zoning
ordinances and/or tax relief in conjunction with the C&D landfill.
In the City of Seattle, new construction, remodeling, and demolition activities are banned from disposing
of asphalt paving, bricks, and concrete; metal; cardboard; new construction gypsum scrap; and
unpainted and untreated wood. During the early part of the 10-year implementation period, the City of
Seattle plans to add carpet, plastic film wrap, and tear-off asphalt shingles to the banned items list. The
program is implemented by first requiring projects with work areas greater than 750 square feet to
develop a waste diversion plan as a component of building permit applications. To demonstrate
compliance, the City requires all demolition projects and new construction and remodeling (that entail
demolition) that receive a building permit to submit an electronic waste diversion report within 60 days
of final inspection. The success of the program is highly contingent on a robust network of Seattle-
certified salvage and source-separated recyclers, including mixed-waste recyclers and disposal facilities
(City of Seattle 2019).
9.7.2.3 Management Options
With C&D representing a significant proportion of the MSW waste stream, there is an opportunity to
divert these materials from disposal and to manage them into productive uses.
2019 Integrated Solid Waste Management Plan Update
County of Hawaiʻi
9-26 August 2020
C&D can be managed in the following ways:
•Recycled–Material separated for recycling.
•Reused–Materials that have or can be salvaged or reused on the same or other construction
projects.
•Beneficially Used–Material that is not recyclable or reusable can be used for other purposes,
such as unpainted and untreated wood used as feedstock for biomass-mass burners or for
groundcover (dog runs), pathways, or temporary roads.
•Disposed–Material permanently placed in a landfill where it could be used as Alternative Daily
Cover (ADC) in lieu of dirt or soil to cover landfill garbage.
9.7.2.4 Benefits
The benefits to limiting the disposal of C&D materials include:
•Provides the largest contribution to job, wage, and tax revenue from C&D recycling, followed by
ferrous and non-ferrous metals (EPA 2016a).
•Reduces purchase and disposal costs.
•Provides a tax benefit if recovered materials are donated to a qualified 501(c)(3) charity.
•Reduces transportation costs if materials are used on site.
•Reduces environmental impacts associated with the extraction and consumption of virgin
resources and production of new materials.
•Conserves landfill space.
Cost Considerations. There would be upfront costs to plan, design, and construct the landfill and sorting
and reuse area; however, when in operation the County would charge a tipping fee, and repurposed
C&D products would also generate revenue.
9.8 Recommendations
As described previously, the County studied various alternatives to expand the existing SHSL or to find
an alternative landfill site in East Hawaiʻi, and determined several significant constraints would interfere
with these efforts. Therefore, trucking and disposal of waste to the existing WHSL is the County’s
singular residual waste disposal option at the time of Plan development. With a final decision on
landfilling, and based on the analyses presented above and discussions with the SWAC, the Plan
recommends the following residual management strategies during the next planning period.
1.Consider recovery and treatment technology for handling of municipal solid waste if all of the
following criteria are met: 1) waste diversion approaches already in operation are ineffectual or
cost-prohibitive in meeting County waste reduction goals, 2) it can be demonstrated that the
technology is environmentally sound and economically feasible, and 3) the technology has a
verifiable and viable commercial track record (minimum of 5 years).
2.Investigate the feasibility of a landfill with a sorting and reuse area for construction and
demolition materials.
2019 Integrated Solid Waste Management Plan Update
County of Hawaiʻi
August 2020 9-27
3.Update infrastructure at the WHSL and EHRSS. The County will continue to conduct periodic
evaluations as needed to improve facility operations and efficiencies at WHSL and EHRSS in
response to changes in flow patterns and increased volume. Activities could include:
Integrate compaction into the floor space of the EHRSS.

10.ADMINISTRATION, FUNDING, AND IMPLEMENTATION
10.1 Introduction
The current solid waste management programs, as discussed in previous sections, are primarily
administered and funded through various state grants, property taxes, and tipping fees. Departments
within the County of Hawaiʻi develop their budgets on an annual basis. The budgets and funding are
submitted by the mayor’s office and approved by the County Council.
This chapter describes current conditions of the existing administration and funding within the County,
identifies current issues and concerns, presents options currently under consideration by the County,
and provides a recommendation for implementation.
10.2 Review of 2009 Plan Update
Exhibit 10-1 below provides a summary of the recommendations put forth in the 2009 Plan update
relative to administration, funding, and implementation, and describes the actions taken to achieve
each recommendation.

10.3 Existing Conditions
The County accounts for revenues and expenses for solid waste management in its solid waste fund.
Revenues are received from state and county sources. The state provides grants and subsidizes
programs, such as glass recycling, e-waste recycling, and the beverage container deposit program (HI-5).
State funding is generally allocated based on County population or County’s budgetary requests to the
state for program administration. The sources of solid waste funding from the County primarily include
revenues transferred from the general fund and revenues from fees associated with solid waste disposal
at the landfills. In addition, the County typically finances large capital improvement projects with general
obligation (GO) bonds.
Budgets for the solid waste fund and capital improvement program are created on an annual basis and
approved after a review process by the mayor’s office and the County Council that includes public
testimony.
10.3.1 Solid Waste Fund Revenues
Exhibit 10-2 presents FY 2017–18 actual and FY 2018–19 budgeted revenues for the solid waste fund.

10.3.1.1 State Programs
Glass Recycling. The glass recycling program consists of glass containers not included in the state
Beverage Container Deposit Program. The program is administered through the state and is subsidized
with an advance disposal fee (ADF), currently at 1.5 cents per container. The state allocates funds from
this program to the counties based on the population size of each island and distributes these funds on
a quarterly basis.
Beverage Container Deposit Program (HI-5). The Beverage Container Deposit Program is a state-
administered program, which places a 5¢ redeemable deposit on each beverage container, as defined
under law. Consumers may then return the container to redeem their 5¢ at any redemption center. A 1¢
non-refundable container fee is assessed to support the costs of recycling and program administration.
Any funds that are not redeemed by consumers may be distributed to County-based programs. The
County submits a list of requests to the state on annual basis, outlining budgetary needs for HI-5
projects and program administration.
Electronic Device and Television Recycling Law. The Electronic Device and Television Recycling Law
(Chapter 339D-7.5) reinforces product stewardship by requiring manufacturers of electronics to run
recycling programs to comply with local government regulations. Manufacturers of covered electronic
devices (CEDs) sold in the State of Hawaiʻi must register with HDOH and pay an annual registration fee
of $5,000 and must set up recycling plans. Television manufacturers must follow the same protocol
except for the fee, which is $2,500 annually. Any manufacturer that sells both CEDs and covered
televisions (CTVs) are required to pay a combined $7,500 in annual registration fees. The state allocates
funds from this program to the counties based on the population size of each island and distributes
these funds on a quarterly basis. According to HDOH, these programs have been scaled back because of
budget constraints (HDOH 2015).
The State Revolving Fund (SRF) program. The SRF program assists local governments in the financing
the construction of water pollution control projects necessary to prevent contamination of our
groundwater and coastal water resources and to protect and promote the health, safety and welfare of
the citizens through awarding of low interest loans. Since the 2009 Plan, the County has benefited from
the SRF to finance stormwater-related projects at their recycling and transfer stations.
The County may request additional funds during the year for more redemption centers, shelters, bins, or
public awareness programs.
10.3.1.2 County Programs
Landfill Tipping Fees and Permit Fees. The County generates revenue from solid waste disposal through
landfill tipping fees and permit fees. In 2019 non-residential customers paid $110 per ton of solid waste
to the landfill, and for customers that dispose of waste on a routine basis, a $25 one-time annual fee is
assessed for account setup and administration costs. Businesses, agencies, farms, and nonprofits are
subject to a $27.50 per ton tip fee for source-separated green waste.
Customers may also pay special handling fees on non-routine disposal of solid wastes that require
additional personnel or costs for disposal (i.e., solid waste that requires special storage, handling, or
disposal practices such as asbestos or petroleum-contaminated soil).
Transfers from the General Fund. The primary revenue source for County solid waste programs is
transfers from the General Fund. Property taxes account for the largest portion of the General Fund.
Other fund sources include hotel/tourism taxes, public service company taxes, interest on invested
funds, and any carryover of the General Fund balance from the prior year. Each County department
2019 Integrated Solid Waste Management Plan Update
County of Hawaiʻi
10-4 August 2020
forecasts its budgetary needs for the year, and the Mayor’s office and County Council approve the
budgets pending a review process.
10.3.1.3 Other Programs
Abandoned Vehicle Program. The abandoned vehicle program is funded directly from a portion of the
vehicle registration fee. The program receives $25 per registered vehicle to pay for program
administration, towing companies, and scrap metal vendors.
Residential Hauler Credit. Vendors that charge a fee for residential waste pickup may qualify for a
residential hauler credit. To qualify, the vendor must have a physical address of each customer. The
annual credit to the vendor is determined by the annual number of single-family accounts multiplied by
a factor of 1.5 (tons per year per customer) multiplied by the landfill tipping fee (e.g., $110/ton).
10.3.2 Solid Waste Fund Expenses
FY 2017–18 (actual) and FY 2018–19 (budgeted) expenses for the County solid waste fund are shown in
Exhibit 10-4. Expenses have been grouped into categories that reflect the main solid waste functions
provided by the County. The expense groupings shown were prepared by an allocation process in which
greater than 500 lines of expenditures were assigned to functions using appropriate, available data and
professional judgment by County staff.

Note: Totals may not add because of rounding.
As shown, budgeted expenses for FY 2018–19 are higher than FY 2017–18 actuals. Expenses are
projected to increase because of inflation, waste stream increases, increased staffing at recycling and
transfer stations, tariffs, import bans, and substantial reductions in forecast prices received for recycled
materials. Also, due to the 2018 Kilauea Volcano lava event, many properties were devalued, which
resulted in the loss of real property tax revenues, the main source of taxes to the general fund. As
shown in Exhibits 10-2 and 10-3, the general fund is the primary source of revenue for the management
of solid waste in the County.
Exhibit 10-5 provides the SWD’s prioritized capital improvement funding request as submitted to the
County Council. These improvements have been included in the Capital Improvement Program forecasts
shown later in this section. As shown, the County also made provisions for SHSL closure requirements.
Closure and post-closure requirements for the WHSL are the responsibility of the County’s contractor.

10.4 Issues and Concerns
As discussed in prior sections, the County is considering several potential changes to the current waste
management program. Some of the options currently under consideration could be implemented
relatively easily and integrated as part of the County’s existing waste management system. Other
options will require more significant changes including new infrastructure, new administrative positions
within the County, coordination with other County agencies, community outreach, behavioral changes
by the public (paradigm shift), and in some cases, will require passage of policies, ordinances, and
legislation requiring public and commercial participation.
A central issue for the County is determining the best policies and procedures to fund both existing and
new waste management programs and initiatives. Currently, residential customers can deliver waste to
County recycling and transfer stations at no charge, while commercial haulers must pay tipping fees at
the landfills. As shown in Exhibit 10-4, the FY 2017–18 County general fund provides approximately two-
thirds of the revenue used to fund current solid waste expenses (excluding debt financing for major
2019 Integrated Solid Waste Management Plan Update
County of Hawaiʻi
10-6 August 2020
infrastructure). This aligns with the 2009 Plan update. However, general fund transfers supporting solid
waste expenses are expected to drop to around 50 percent in FY 2018–19 compared to about 60
percent in FY 2017–18. This is attributable to excess monies from the FY 2017–18 general fund that are
expected to carry over to FY 2018–19, and to a lesser extent, an increase in state grant contribution to
the glass recycling, e-waste, and beverage container deposit programs.
In FY 2017–18, about 36 percent of the funding was derived from landfill tipping fees, and in FY 2018–
19, tipping fees are estimated to contribute closer to 32 percent. Except for a projected lessened
reliance on the general fund in FY 2018–19, these percentages are relatively unchanged from those
reported in the 2009 Plan update. This indicates that few changes to the overall funding structure have
occurred since the last planning effort, although tipping fees have increased from $85 to $110 per ton
during the past 5 years. According to Ordinance Number 18-5 (Appendix F), which amends HCC 20 of
the, the landfill charge rate per ton cannot exceed $116 in 2022. Exhibit 10-6 shows a breakdown of the
landfill charge rates through 2022 (Ordinance No. 18-5).
Exhibit 10-6. Landfill Charge Rates 2018-2022
2018 2019 2020 2021 2022
$108 $110 $112 $114 $116
The funding mechanisms, administration, and types of programs and legislation required to implement
modifications to the existing waste management program will depend on the options selected for
implementation in this Plan update. It is likely that additional regulations will be necessary to
successfully implement changes to the County’s current program and to encourage changes in the
current patterns of waste disposal by both the public and commercial businesses.
Three key issues facing the County that may require legislative changes include:
•Increasing diversion by thinking of waste as a resource and reducing wasteful behavior.
•Minimizing or eliminating illegal dumping.
•Reducing contamination at the recycling and transfer stations and green waste facilities.
In addition to legislation and ordinances, community outreach and education will also be necessary to
effect a change in public perception of the issues surrounding waste management, and thereby influence
established behavior patterns. As community involvement and concern for waste-related environmental
stewardship increase, it is expected that acceptance of additional fees and regulation regarding waste
disposal practices will become more widely embraced by the public and commercial sectors.
As part of the Plan update process, the County is evaluating potential options and setting both
recommendations for waste management. To successfully expand and adapt the current county-wide
waste management program to meet its goals, the County will need to:
•Make decisions regarding the path forward according to the Plan’s recommended priorities.
•Take advantage of best practices and lessons learned from other jurisdictions regarding funding
and administration mechanisms, and related legal and regulatory requirements.
The County must also consider the potential implications of various existing Federal, State, and County
regulations on the implementation of the waste management program.

County of Hawaiʻi
August 2020 10-7
10.5 Administration and Funding Options
Many of the options being considered in previous chapters of this Plan update would require changes to
existing methods of administering and funding programs. Some administration and funding options for
consideration follow.
10.5.1 Establishing Solid Waste as an Enterprise Fund
As discussed above, about two-thirds of the County’s expenditures for solid waste management are
currently funded by the County’s general fund which is primarily supported by property taxes. There are
some disadvantages associated with the current funding system, including:
•Property tax funding provides no financial incentive for residents to reduce waste.
•Using property taxes to fund solid waste services can be perceived as unfair because property
tax collections are not correlated specifically with the types and volumes of waste generated,
potentially leading to inequitable subsidization.
•It can be somewhat more challenging to manage solid waste programs based on funding
allocation of money from the general fund, because the money in the general fund may be
redirected towards other pressing county needs.
Another funding mechanism for solid waste systems costs commonly used in many communities is to
establish a self-sustaining enterprise fund. An enterprise fund can be supported primarily by user fees,
dedicated taxes, or dedicated property taxes. Some advantages often cited for enterprise funds include:
•Promoting fairness by charging specifically for waste composition and volume disposed.
•Reducing burden on the general fund.
•Requiring more sensitivity to customer’s needs.
•Allowing managers more discretion; however, still holding them accountable to customers.
•Running government more like a business.
The main disadvantages cited for enterprise funds is that they can be regressive and place a burden on
the poor by increasing the amount they must pay for an essential service like waste management.
Enterprise funds also may be more cumbersome to administer (management of financing) and politically
unpopular for those with the expectation that solid waste is subsidized through the general fund.
Several factors would be considered to establish an enterprise fund system:
•Determine local authority (i.e., Can the County legally charge solid waste management user
fees?).
•Gain support from decision makers.
•Decide the appropriate type of user fees to support the enterprise fund.
•Perform full cost accounting to identify and report costs of operation, including the preparation
of a long-range budget.
•Educate the public.
2019 Integrated Solid Waste Management Plan Update
County of Hawaiʻi
10-8 August 2020
10.5.2 Separating Solid Waste Management as a Line Item on
Property Taxes
The County could provide additional information to customers about the cost of managing solid waste
by adding a separate line item on property tax bills outlining the amount of the tax used to fund solid
waste services. A possible breakdown might include the three primary categories of expenses shown in
Exhibit 10-3: SWD Operations, West Hawaiʻi Sanitary Landfill, and Recycling Programs. The addition of a
line item on property taxes would be an interim step to educate the public on the breakdown and costs
of solid waste management.
10.5.3 Establish PAYT System at County Recycling and Transfer Stations
As discussed in greater detail in Chapter 3, there are several ways that the County could implement a
PAYT system at recycling and transfer stations. A PAYT program may be implemented via:
•Charging residents’ solid waste by weight through the addition of scales at County recycling and
transfer stations while accepting drop-off of recyclable or compostable materials at no charge.
•Charging residents’ solid waste by volume where residents pre-purchase tags and/or bags that
they would then place their waste in and haul to their nearest recycling and transfer station.
•Charging residents’ solid waste by volume being disposed of, while allowing drop-off of
recyclable or compostable materials.
•Implementing universal curbside collection of garbage for all households in the County where
practical.
Two methods that would minimize staffing requirements at the stations include a “tag” or “bag” system.
In a tag system, property owners would be issued tags along with their semi-annual property tax bills
that could be used as “currency” for delivering waste, and extra tags could be available for purchase at
County offices or retail outlets. Arrangements would need to be made for renters not served by a
building collection service.
A bag system would consist of requiring all residents to put waste into a standard type of plastic bag
that would be available for purchase at County offices and/or retail outlets.
There would be many implementation challenges associated with this system. An extended phase-in
period would be necessary accompanied by an intensive public education program. A PAYT program
could be a user fee option integrated into an enterprise funding program (see Section 10.5.1). This
program has been shown to work in other jurisdictions on the mainland and in Hawaiʻi (e.g., Kaua’i).
10.5.4 Modifications to Existing Programs and Practices
The County could consider modifications or improvements to existing programs that may increase
revenue instead of changing funding mechanisms (e.g., enterprise fund):
•Seek more non-user-fee funding (e.g., federal grants, opportunities such as SRF).
•Increase recycling rates through improved operations (e.g., public outreach, transfer and
recycling station upgrades).
•Determine adequacy of handling fees on non-routine solid wastes (e.g., asbestos, petroleum-
contaminated soil).
•Increase participation of the hotel/tourism industry through tax incentives or other
mechanisms.
2019 Integrated Solid Waste Management Plan Update
County of Hawaiʻi
August 2020 10-9
•Determine adequacy of the registration fee for the abandoned vehicle program.
•Reevaluate the residential hauler credit program.
•Regularly review and, when appropriate, renegotiate the WHSL contract.
10.5.5 Illegal Dumping Prevention
Illegal dumping of household and commercial waste can have a variety of potential negative impacts.
Hazardous chemicals generated from illegally dumped waste can contaminate groundwater and surface
water, potentially affecting both human health and aquatic habitats. Flooding can result from blockage
of streams and drainage culverts. Property values can be affected by illegal dumping, economic impacts
resulting from costs of clean up can affect County resources, and illegal dumping degrades quality of
life –the beauty of the island for residents and visitors. Additional efforts to prevent illegal dumping
would be particularly important if the County were to implement a PAYT program or dramatically
increase the tipping fee.
This section describes existing regulations at the federal, state, and local level. It also describes illegal
dumping prevention measures within the County, issues and concerns, and options to deter illegal
dumping that have the potential to bolster the County’s existing prevention system.
10.5.5.1 Regulations
At the federal level, Statute 42 United States Code (USC) 6928(d)(2)(B) & (C) of the Criminal Provisions of
the Resource Conservation and Recovery Act (RCRA) indicts offenders who knowingly treat, store, or
dispose of hazardous waste without a permit with penalties up to 2 years of incarceration and a
$50,000 per day in fines.
The County regulates “littering” and the state regulates “illegal dumping.” The state defines illegal
dumping as the illicit disposal of solid waste that is equal to or greater than 1 cubic yard. The County’s
litter law does not quantify what is considered litter; therefore, it could be less than or greater than 1
cubic yard.
In accordance with Hawaiʻi Revised Statutes Chapter 342H (HRS 342H), illegal dumping could be subject
to enforcement action and administrative civil penalties up to $10,000 per day. Those who knowingly
dispose of solid waste equal to or greater than 1 cubic yard and less than 10 cubic yards are subject to
criminal penalties (petty misdemeanor) up to $25,000 per day for each offense. If illegal dumping is
equal or exceeds 10 cubic yards, it is considered a class C felony and potentially subject to $50,000 for
each separate offense. If illegal dumping is suspected, a complaint can be filed with the State
Department of Health, Solid and Hazardous Waste Branch, State Department of Attorney General
Investigations Office, District Health Office located in Hilo, or Hawaiʻi County Police Department (HCPD).
Hawai'i County Code (HCC 20-8) contains provisions that prohibit littering. In the past five years,
revisions such as Ordinance 12-1, aimed at reducing plastic bag littering and pollution, have been
enacted to further reduce contamination. These provisions cover the materials commonly encountered
in the municipal waste stream and prohibit discarding or disposing of these materials on either public or
private property. Violators may be fined up to $1,000 and/or not more than 200 hours of community
service for each offense. Cost recovery for cleanup is also allowed under the current County code.

10.5.5.2 Countywide Illegal Dumping Prevention
The County’s HawaiiZeroWaste.org website provides a wealth of information related to illegal dumping
including:
•A link to “Trash Free Hawaiʻi” website, an initiative by the State of Hawaii Department of
Transportation (DOT), Highways Division, and O`ahu District’s Storm Water Management
Program, which seeks to reduce litter entering the storm drains that ultimately enter the ocean.
•State of Hawaiʻi’s regulations, including information related to potential hazardous
contaminants that may be within commercial or industrial waste from small quantity
generators.
•Education of the potential health consequences of open dumps (illegal dumps).
•Actions that can be carried out by private landowners, contractors, and “everyone” to address
and prevent illegal dumping, including reporting procedures.
•A link to a brochure that describes how to conduct a community cleanup of a dump site.
•Contact information for the County Department of Public Works, Highways Maintenance
Division, to request rubbish removal in County right-of-way.
•Information emphasizing the role of small businesses in the handling of hazardous materials,
including a link to HDOH guidance and other resources.
The County holds household hazardous waste collection events per year at well-known and well-
publicized locations in Hilo, Kona, Waimea, and Pāhoa. Chapter 6 provides further information regarding
the handling of hazardous waste.
The 501(c)(3) nonprofit, Keep the Hawaiian Islands Beautiful website, provides an online litter “hotline”
as another avenue to report illegal dumping. The nonprofit’s mission emphasizes the engagement of
individuals to take a greater responsibility for improving the community environment and preserving the
beauty of the Hawaiian islands. Solid waste initiatives and recycling, beautification, and litter prevention
and control are activities emphasized by the nonprofit.
10.5.5.3 Issues and Concerns
Regardless of the existing regulatory framework and “grassroots” approach to prevent illegal disposal of
rubbish, illegal littering or dumping still occurs, notably along roadways in more rural areas, on vacant
lots, and in gulches with major roadways crossing them or near industrial facilities. Enforcement of
existing illegal dumping and litter laws is challenging due in part to the rural nature of the County.
Currently enforcement of the County code is the responsibility of the HCPD. Because littering is not one
of the higher priorities for HCPD, many of the violators who litter are not caught or penalized. DEM staff
do not have the training or legal authority to enforce litter laws. The County would increase its potential
liability if it required DEM employees to enforce policy, even within the confines of County recycling and
transfer station properties.

10.5.5.4 Options to Prevent Illegal Dumping
Illegal Dumping Prevention Studies
It is anticipated that passing ordinances or legislation that requires the public to pay for waste disposal
on a per unit basis may, in the short term, increase the occurrence of illegal dumping. Studies conducted
in rural areas of Kentucky concluded that when additional fees were implemented for public waste
disposal, illegal dumping increased, especially in areas where a higher percentage of the population had
low or poverty-level incomes. However, most jurisdictions implementing programs such as PAYT
reported only short-term increases in illegal dumping, and a decline to pre-implementation rates of
incidence within the first 1 to 2 years after implementation. Exhibit 10-7 presents four programmatic
areas the EPA has suggested focusing on for preventing illegal dumping.
Exhibit 10-7. Four Programmatic Areas for Preventing Illegal Dumping (EPA 1998)
Source: EPA (1998)
The New South Wales Environmental Protection Agency conducted a report on illegal dumping including
an online survey consisting of 63 government authorities, 100 trade and industry authorities, and 1,009
community members. Respondents were given various methods to reduce illegal dumping and were
asked to rank their effectiveness. Patrolling and surveillance were viewed as the most effective, with 81
percent of participants responding that the method was “somewhat or very effective.” Community
outreach and education was viewed by 77 percent of participants as “effective,” and fines/enforcement
were viewed by 70 percent of participants as “effective.” Relating to joint campaigns with the New
South Wales EPA, 56 percent of local government authorities stated the method was “very effective,”
while signage received the least support with 43 percent of respondents stating the method was “not
Cleanup Efforts. Cleanup projects will require a coordinated planning effort to ensure that adequate resources and funding
are available. Once a site has been cleaned, signs, lighting or barriers may be required to discourage future dumping. Signs
should indicate the fines and penalties for illegal dumping, and a phone number for reporting incidents. Landscaping and
beautification efforts may also discourage future dumping, as well as provide open space and increase property values.
Community Outreach and Involvement. This may be the most important tool in ensuring that this practice is effective. The
organization of special cleanup events where communities are provided with the resources to properly dispose of illegally
dumped materials increases the understanding among residents of illegal dumping impacts and supplies opportunities to
correctly dispose of materials which may otherwise be illegally dumped. Integration of illegal dumping prevention into
community policing programs or use of programs such as Crime Stoppers may also be an effective way to increase
enforcement opportunities without the additional cost of hiring new staff. Producing simple messages relating the cost of
illegal dumping on local taxes and proper disposal sites will aid in eliminating the problem. Having a hotline where citizens
can report illegal activities and educating the public on the connection between the storm drain and water quality, and
other potential hazards associated with dumping refuse into streams or drains will decrease disposal of waste into streams
or storm drain inlets.
Targeted Enforcement. This tool involves the use of ordinances to regulate waste management and eliminate illegal
dumping through methods such as fines, cost recovery penalties for cleanup, and permit requirements for waste
management activities, to name a few. These fines and penalties can be used to help fund the prevention program or to
provide rewards to citizens who report illegal dumping activities. Other recommendations for this tool include training of
staff from all municipal departments in recognizing and reporting illegal dumping incidents, dedicating staff who have the
authority to conduct surveillance and inspections, and writing citations for those caught illegally dumping.
Tracking and Evaluation. This tool measures the impact of prevention efforts and determines if goals are being met. Using
mapping techniques and computer databases allows officials to identify areas where dumping most often occurs, record
patterns in dumping occurrence (time of day, day of week, etc.), and calculate the number of citations issued and the
responsible parties. This allows for better allocation of resources and more specific targeting of outreach and education
efforts for offenders.

performed by the New South Wales EPA.

Illegal Dumping: County’s Options
A combination of passing more severe penalties for illegal dumping, targeted enforcement actions by
HCPD, establishment of new community outreach and participation programs, and other actions found
to be successful in other jurisdictions may help to curb illegal dumping in the County. Potential actions
that may be considered for the County to prevent illegal dumping are listed below.
•Civil and Criminal Penalties. Develop legislation that sets more severe civil and criminal penalties
for illegal dumping activities than what is legislated by the state (HRS 342H). Legislation could be
worded such that the penalties increase with the egregiousness of the violation, and based upon
a weight, volume, or types of material that are dumped, and location of illegal activity (that is,
higher penalties for dumping into streambeds). Legislation could require violators to pay for
consequential damages and cleanup costs resulting from specific violations.
•Targeted Enforcement. Work with the community and the HCPD to develop a targeted
enforcement program. Incentives could be offered for monitoring and reporting of illegal
dumping to authorities, and methods could be developed for periodically evaluating illegal
dump sites for evidence of the identity of the violators. Legislation supporting prosecution of
violators based on the evidence of ownership at the time of the violation derived from dumped
materials may need to be developed to effectively implement such a program.
•Community Education, Outreach, and Involvement. Develop programs with school and
community groups or organizations to emphasize prevention, and conduct periodic clean ups of
illegal dump sites, to raise community awareness and involvement in reducing illegal dumping
activities.
•Install Signage at Problem Areas. Install signage where illegal dumping typically occurs listing the
more severe civil and criminal penalties for violators to curb future dumping. This process may
be completed in conjunction with the planned re-signing at recycling and transfer stations, as
stated in Chapter 5, Public Education and Information.
2019 Integrated Solid Waste Management Plan Update
County of Hawaiʻi
August 2020 10-13
•Increase Security at Recycling and Transfer Stations. Hire full-time attendants to monitor the
recycling and garbage facilities to deter potential violators. Install a fence around Miloli’i to
reduce illegal dumping during non-operating hours.
•Small Quantity Generator Program. Inform small businesses how to best dispose of their
hazardous waste to reduce illegal dumping and contamination. Businesses who are small
quantity generators (SQGs) and produce between 100 and 1,000 kilograms per month of
hazardous waste may accumulate waste for up to 180 days without a permit. As described in
Section 10.5.5.2, the County provides information and guidance targeting businesses (SQGs) on
their HawaiiZeroWaste.org website. This program could be bolstered by initiatives such as
County interaction with small businesses through meetings and site visits.
•Recycling and Transfer Stations. Allow small businesses to utilize the recycling and transfer
stations for recycling (see Recommendations, Chapters 4 and 8).
10.6 Plan Recommendation
Exhibit 10-9 outlines the 10-year funding projections for the 84 recommendations identified throughout
this Plan. Fluctuations in markets and uncertainties regarding the outcomes of programs that will be
operational early in the planning period will likely involve the County continuing with the current system
of funding most operating expenditures using property taxes and tip fees until the outcome of programs
are better understood. The County must ensure that DEM has resources commensurate with the needs
of all current and future solid waste programs. Based on the analyses presented above and discussions
with the SWAC, the Plan recommends implementing the following administrative activities during the
next planning period:
1.Prepare a Solid Waste System Financial Analysis. Prepare the analysis to align with programs
identified in this Plan and to achieve less reliance on the general fund. Major capital
expenditures would continue to be funded through general obligation bonds. The planning
effort would also consider methods and costs associated with the discouragement of illegal
dumping, particularly because there is a correlation between this undesirable activity and the
implementation of a PAYT program.
Note: Chapter 3, Section 3.6 (Recommendation 2) discusses the analysis of a PAYT program or
other funding mechanism for source reduction. Chapter 8, Section 8.8 (Recommendation 1)
discusses the continued operation and maintenance of recycling and transfer stations until a
decision on the best method of collection and transfer is determined, and to also explore
alternative funding mechanisms via a feasibility study.
2.Regularly review and, when appropriate, renegotiate WHSL contract.

1.INTRODUCTORY REMARKS
Keyra Wong, Deputy Corporation Counsel
William Kucharski, Director
Diane Noda, Deputy Director
Gregory Goodale, SWD Chief
Tina DeMello, Secretary
Mary Fujio, Assistant Secretary
Opening and introductory remarks were made by Gregory Goodale at 10:10 a.m.
Mr. Goodale introduced himself as the Solid Waste Division Chief for the Department of
Environmental Management and expressed his appreciation to all the members for
being a part of the Solid Waste Advisory Committee (SWAC) and for making the
commitment to help the County. He explained he is not technically a part of this group
but wants to welcome everyone and express appreciation for the Mayor appointing
everyone and everyone accepting to be a part of this committee.
Mr. Goodale introduced the following people: William Kucharski, Director of
Environmental Management, and Diane Noda, Deputy Director of Environmental
Management; Mary Fujio and Tina DeMello, who work with the Department and will be
helping and assisting at these meetings; Keyra Wong, Deputy Corporation Counsel;
David Tamas, who will be helping with facilitating these meetings; and Dennis Lee, who
is the Senior Project Manager Dennis Lee and a consultant with Wesley Segawa and
Associates (WSA), which is the prime consultant for this project.
Mr. Goodale turned it over to Director William Kucharski to say a few words.
Mr. Kucharski thanked everyone for being part of this committee. It is an important
effort on the County's part to plan and planning is important. He thanked the members
1
for volunteering to be on the committee, because the plan is critically important to the
County and the people who live here. His door is always open, and if there are any
issues, don't hesitate to ask him ..
2. INTRODUCTION OF COMMITTEE MEMBERS AND STAFF
George Hayducsko gave an overview of who he is. Most of his career was in Wisconsin,
where he worked for three different counties and designed two recycling programs. He
has over 30 years of experience from landfills to waste to energy, and he designed two
successful recycling programs. He hopes his experience will help Hawai'i County in this
process. He thanked all of the members for being here and taking time out of their day
to volunteer for the community in helping making the recycling and solid waste
programs better. He asked the committee to introduce themselves and explain their role
today and connection with solid waste and recycling.
Barbara Bell: She was the Executive Director for Recycle Hawai'i before Paul
Buklarewicz for a couple of years. She was also on the last two SWAC commissions
and through that became the Director of Environmental Management, from where she
retired in 2007.
Adam Scharf: He works currently at Pohakuloa Army Training Area as the Program
Manager of Solid Waste and Recycling for the United States Army on the Big Island.
Pohakuloa manages over two million pounds of refuse a year and began a quality
recycling program 38 months ago. They were at a five percent diversion rate, diverting
waste from the County of Hawai'i's landfill. They are tracking 63 percent of all refuse
generated at Pohakuloa and diverting it from the County's landfill by way of composting
(food waste, grind and chip wood and turn it into organic matter). They also manage all
the metals, ferrous and nonferrous. He has a lot of boots-on-the-ground experience in
building programs, approaches, and techniques to approve diversion rates. He
recognizes the importance of this committee, and that's why he had volunteered to be a
part of it. He does a lot of data analysis and analyzes the waste stream on a regular
basis to come up with metrics and posts and tracks the data to ensure they are always
tracking who the large contributors are and what they are contributing, and then build
programs around that and measure improvements. He knows he would be of value to
this committee to help build a better plan for the next ten years.
Georjean Adams: She is currently retired and is the Vice President and secretary for
Recycle Hawai'i. She is also on the board of the homeowners Association for where she
lives at Mauna Lani Resort. She started her life as a Junior Bureaucrat with EPA after
graduating college and worked with a group that defined what hazardous waste was.
Then she got a job at 3M, where the focus was on product stewardship/lifecycle
management, trying to figure out how to make sure that products that 3M makes do not
cause issues upon disposal. She has been active with the American Chemical Society
and has worked as an independent consultant for three years. She brings an industrial
perspective, working with companies and their products and issues on how to manage
2
waste through the commercial stream. As a resident of this island, she wants to keep it
the best and make it better.
Steven Araujo: He owns and operates D&D Rubbish Service and have been doing it for
twenty-five years. He started back when Steven Yamashiro was mayor and has seen
the changes from that time until now. He does believe in some of the programs and is
also a realist, asking questions such as is it going to work? How much is it going to cost
the taxpayer, is there an actual benefit? And how is this going to affect his business and
the rest of the rubbish businesses?
Paul Buklarewicz: He has been the executive director for Recycle Hawai'i for the past
15 years. Recycle Hawai'i is a 501 (c) (3) nonprofit. Education is the primary mission,
and resource management recycling promotion. He has been facilitating, initiating and
expediting a lot of the recycling programs here on the island (E-waste collection, used
motor oil, home composting) and along with Barbara served on the last go around of the
Solid Waste Advisory Committee ten years ago.
Keyra Wong: She is a deputy corporation counsel and advises DEM, DPW and the Real
Property Tax Division. Her capacity here is to help this committee and provide legal
advice.
Robert Ely: He is a retired chemical engineer and environmental engineer and is 77
years old. Right now he is fully employed as a consultant in a project that has nothing to
do with what the SWAC is about. He provided some background on projects he has
worked on --the design and management of Chem's Security Systems Hazardous
Waste Landfill at Arlington Oregon; Casmalia Hazardous Waste Landfill in Casmalia
California; he worked for Zeffro, which is based in Wisconsin, as a manager of process
design on sludge management systems; he helped design the anaerobic digestive
systems for Alaska Lumber and Pulp in Sitka Alaska; he got involved heavily in the
Ainakoa Pono Project and came in contact professionally with Bill Kucharski when Bill
was with AECOM; and during the last go around with the incinerator, he worked for
Covanta as a consultant looking at both political aspects and technical aspects. He is
hoping to lend professional expertise to this group.
Alan Okinaka: He is a retired manager from GTE Hawaiian Tel. He was formerly an
electrical engineer and initially managed technology but ended his career managing
people. He feels the least certified with anything to do with solid waste management,
but being a part of the committee is privileged to be a part of group that is trying to
manage something that is very difficult to solve. Has two compost piles and embraces
1, 2 and 5 plastics for recycling. He gets upset if he has more than one 32 gallon bag of
trash every week and flattens all corrugated boxes down religiously.
Mr. Okinaka asked how the Environmental Management Commission, the Solid Waste
Commission and the Department of Environmental Management interact. Mr. Goodale
responded that Bill Kucharski and Diane Noda oversee the Department of
Environmental Management and the two divisions that are within it, which are the Solid
Waste Division and the Wastewater Division. The Environmental Management
3
Commission's members are also appointed by the mayor, and it is more of a formal
commission that address solid waste management issues as well as wastewater
management issues. The SWAC takes on solid waste management by itself and is
required by the State of Hawai'i to develop an updated plan every ten years.
Ms. Noda explained that the Environmental Management Commission is created by the
County Code, and part of its duties are to advise the Department on solid waste and
wastewater programs, including waste reduction strategies, recycling, litter control,
community involvement, and other issues. The Solid Waste Advisory Committee is
created by State law, and its limited purpose and limited duration is only until our
revised solid waste plan is submitted to the State Office of Solid Waste Management.
The deadline for this is November 2019. A consultant has been hired to submit the plan.
She explained the binders they were given included HRS Chapter 342G which
addresses the Integrated Solid Waste Management Plan. It establishes that each
County is to have a committee appointed by the mayor. This committee is convening
because the ten-year mark is next year.
3.STATEMENTS FROM THE PUBLIC
None
4.ELECTION OF CHAIR AND VICE CHAIR
Mr. Buklarewicz nominated George Hayducsko as chair and Ms. Bell seconded the
nomination, and all voted in favor.
Ms. Adams nominated Mr. Okinaka as vice chair; Ms. Bell seconded the nomination;
and all voted in favor.
Ms. Noda explained that the Charter points out that for an advisory committee, you
would need a majority of those present to make any action valid, and for a committee of
eight members, they will need five for a quorum.
5.NEW BUSINESS
a.Orientation by Office of the Corporation Counsel on:
(1) Sunshine Law
Ms. Wong provided a brief overview of the Sunshine Law. It applies to this committee
because this body was created by State statute; and committees, boards and
commissions created by State statute are subject to the Sunshine Law. According to the
County Charter, Section 13-20, this committee is subject to open meetings provisions.
This committee has broad discretion to make decisions and form public policy. They
have to protect the public's interest and the right to know about the committee's
decision-making and deliberations. The Sunshine Law requires no discussing board
4
business outside of an open meeting. Every meeting must be open to the public, unless
there is an executive session or limited meeting as allowed by statute. Boards must
provide notice, accept testimony, and keep minutes; and they cannot consider matters
not included on the agenda. This becomes important because people from the public
may testify on matters not on the agenda. If that happens, it would be the chair's role to
tell that person it is not on the agenda. Committee members also should not allow a
discussion to get tangential, because the public would not have had the right of notice
and would not have known that would have been discussed. Basically, they cannot
discuss issues that are not on the agenda.
Mr. Scharf asked whether, if they were working on a component of this project and he
had a question for Mr. Okinaka, he could call him and ask the question or if he had to
ask it at an open meeting. Ms. Wong said it had to be at a meeting. Two members are
allowed to discuss matters but cannot commit to voting on anything.
Mr. Okinaka whether the committee has the authority to accept public testimony on
something that isn't on the agenda, and Ms. Wong said they would have to amend the
agenda by 2/3 votes to accept the topic. If it's a reasonably important topic that would
affect a number of people it cannot be added to the agenda, and it could be placed on
the next agenda. It is up to the chair's discretion.
Mr. Buklarewicz said that Ms. Adams is on the Board of Directors for Recycle Hawai'i,
and he is not on the board but attends the meetings. If the SWAC has discussion on
something that is also discussed at the board meetings, he and Ms. Adams may need
to recuse themselves. Ms. Wong said that if they discuss matters in the board meetings
that somehow relate to the SWAC and its purpose, then he should not participate in that
discussion. If the SWAC is going to make a decision which would impact how he does
his business, he should recuse himself from voting on that decision.
Ms. Wong continued with her Sunshine Law presentation, as follows:
•"open meeting" requirement. Every meeting will be an open meeting and all
persons will be permitted to attend unless otherwise provided by in the
constitution. Portions of meetings can be closed if they go into executive
session or for other limited exceptions. All meetings will need to be held in a
public place, and board shall take official action and votes in public. They
cannot vote in executive session ..
•If someone is disrupting a meeting to where the meeting cannot carry on, the
chair has the discretion to remove that person.
•Any interested person may submit written or oral testimony on any agenda
item. Most boards set a reasonable time limit of 3 minutes.
•The notice and agenda must list all items that the Board intends to consider,
and the agenda must be sufficiently detailed as to provide the public with
5
adequate notice. The notice and agenda must be filed with the county clerk at
least six days prior to the meeting.
•An agenda may be amended with a 2/3 votes of all members, but an item of
reasonably major importance which would affect a significant number of
people cannot be added. It would need to go on the next agenda.
•The Sunshine Law does not apply to social events attended by board
members in which board business is not discussed, and it does not apply to
non-board members. There should be no discussion with non-board members
regarding matters discussed in closed sessions.
•Two board members may discuss board business outside of a meeting to seek
information so long as no commitment to vote is sought or made. Beware of
serial communications--the language is found in HRS 92-2.5a.
•Other permitted interactions: Ms. Wong described other permitted actions
pursuant to the Sunshine Law.
•Executive meetings are closed to the public. A motion to enter executive
session shall be stated in open session, and a two-thirds vote of the board
members present is necessary in order to go into executive session.
•Minutes are required to include the, date, time and place of the meeting,
members absent or present, the substance of what was discussed, votes
taken, and any other information that any member wants to add to the
minutes. Executive minutes may be withheld, and minutes may be
transcribed or summarized by notes taken.
Ms. Wong said that if the rules are not followed and someone brings an action within
ninety days, a person could actually be charged with a misdemeanor and then removed
from the board.
(2)Rules of Procedure
Ms. Wong explained that the SWAC will follow the general rules of procedure
formulated by a combination of the Robert's Rules of Order, the County Charter, and
the Hawai'i Revised Statutes.
A quorum is the majority of the members of the board or committee, which would be five
for the SWAC. Prior to calling the meeting to order, the chairperson has the duty to
determine whether quorum is present. If quorum is not present, the chairperson either
waits until there is one or, if it is known that quorum is not going to be met, than the
chairperson calls the meeting to order, announces the absence a quorum, and
entertains a motion to adjourn. However, you can still receive testimony and
presentations on the agenda items, and question testifiers and/or presenters, provided
6
that no deliberation, and no decision-making or voting is made until the next meeting.
Members shall create a record of the testimony or presentation, and this would be
presented in the minutes before deliberation or decision-making at the next meeting, the
board is required to present a copy of the testimony and presentations received at the
canceled meeting, and the committee has an opportunity to report to the other members
who weren't there about what was said.
If a member is not able to make it to a meeting, please call the department and let them
know in advance.
Mr. Okinaka asked whether, if a member of the public submitted a large document with
their testimony, if it needed to be accepted, and Ms. Wong said they would need to
receive and accept the whole testimony and document.
Ms. Wong explained that Robert's Rules and general procedures provide for order,
decorum, fairness, efficiency and clarity. Generally when there is a motion, it is then
seconded, then there is a discussion, and then you call for the vote. For boards advisory
boards such as SWAC, the affirmative vote of the majority of those who are present at
the meeting shall be sufficient to make any action valid.
The chair's role is to be the manager of the meetings, and the chair cannot make
motions or second any motion. The chair can only recognize the motion and the
second. The chair must maintain a neutral position to provide credibility for rulings,
protection of minority positions, and to maintain the public's trust. Active participation on
of the chair taints the ability to properly manage the meetings. The chair has to manage
the meeting, help it be productive, and demonstrate the power of process. The chair
may relinquish his or her duties to the vice chair, and it would be best to do so prior to
deliberations taking place. However, the ability to relinquish shall not be used frequently
and cannot be used back and forth for convenience. The acting chair must accept
limitations for the agenda item, keep the peace, and maintain order and decorum.
Leadership and conflict resolution is required both for board members and anyone in
attendance. Public participation should be encouraged, but the rights of one person
should not trump the rights of the rest. It is easier to maintain order if all parties believe
that the chair is being a fair and reasonable person without predispositions.
Everyone should know their role as a board member. The members set the pace. When
motions are made, they should be valid, clearly articulated, and easy to understand.
Avoid getting involved in personality issues, respect others who have the floor, and wait
your turn. If a member wants to make a statement or motion, raise a hand to get the
chair's attention and wait until called upon by the chair. Addressing others casually is
okay; but using surnames is recommended. Keep the meeting on track and don't rely on
the chair to keep discussion focused. If discussion becomes repetitive or irrelevant,
state as much to the chair as a point of privilege, and the chair should redirect
deliberations or call for the vote.
Ms. Wong said she has a cheat sheet on the Robert's Rules available.
Mr. Scharf asked about the process for a special field trip, and Ms. Wong said it would
count as a limited meeting. The State would need to be asked for permission, and the
limited meeting would be closed to the public. Minutes would be required. Members can
discuss but cannot vote. If the SWAC wants to have a site visit, they need to make a
request to the Corporation Counsel, who will help get permission from the State. There
is a requirement to advise the public of the limited meeting and that it is closed for the
public.
Chair Hayducsko called for a five-minute recess at 10:58 a.m.
The meeting reconvened at 11 :07 a.m.
b.Solid Waste Division program overview.
Chair Hayducsko gave an overview of the County's recycling and solid waste programs
using a PowerPoint presentation. The main points are summarized below.
Hl5 Deposit Beverage Container Program -Certified Redemption Centers -We have 11 County sponsored sites at the transfer stations.-There are 8 private Certified Redemption sites around the County.-The Hl5 Beverage Container Redemption Program for FY 2016-2017 diverted
6,071 tons of recyclables from the County's landfill.-The Hl5 percent redemption rate for Hawai'i Island is 87%.
2-Bin Recycling-The 2-Bin program consists of 2 distinct collection bins: a Mixed Recycling bin
and a Glass bin-The 2-Bin Recycling program for 2016-17 diverted 5,990 tons of recyclables from
the County's Landfill.-Signage is provided at the 2-Bin sites at the transfer stations, but they are seeing
quite a bit of contamination at the sites, when the public does not abide by what
recyclables are to be put into the containers. Education is critical and needs to be
done constantly or you will lose the effectiveness of the program.
Mr. Ely asked if there is any data available as to the cost of these individual segments
of the program? Mr. Hayducsko said yes, there is cost associated and it is tracked.
Mr. Scharf asked why there is a drop off in 2Bin recycling and Mr. Hayducsko said the
containers are sometimes not available to the public because they are full, and they are
trying to address that. Mr. Scharf said residents can be lazy, and there is a culture in
the home to dispose of trash in whatever way is convenient. Traffic flow could be
another problem. Chair Hayducsko said these are things that they will need to look at
and address.
Ms. Bell asked what the contamination is percentage wise and whether they had done
a waste comp study recently, and Chair Hayducsko said he was not sure and that a
8
waste comp study had not been done for ten years. They are not anticipating doing
one.
E-Waste Recycling-E-Waste Recycling for FY 2016-17 diverted 235 tons-The County Electronic Waste Recycling Program for residences in Hilo,
Kealakehe, Wai'ohinu and Waimea-The County contracts with Mr. K's. At Mr. K's it is free for residences on
Saturdays (the County subsidizes on Saturdays), and there is a reduced rate on
Saturday for commercial entities. Sunday to Friday there is a fee for both
residence and commercial entities.
Household Hazardous Waste (HHW) -Over 2,882 participated in HHW during FY 2016-FY 2016-17 collected 53 tons of materials-There are 4 locations Island wide: Hilo - twice a year, Kealakehe -twice a year,
Waimea -once a year and Pahoa - once a year.
Mr. Okinaka asked how much it costs to run a day of collecting hazardous waste, and
Chair Hayducsko said it costs around $50,000 per event. The contractor required to
provide personnel and move items collected off island. There is no disposal site on the
island.
Scrap Metal/White Goods/Automobiles -Scrap Metal/Automobiles(AV) for FY 2016-17 diverted 9075 tons
Used Motor Oil -16,547 gallons of Used Motor Oil was processed for FY 2016-17-The County has volunteer Used Motor Oil collection sites, island wide.
Mr. Ely asked what is meant by "processed", and Mr. Hayducsko said it means what is
received and taken for re-use--lt is not just collected and stored, it is being utilized.
Tire Education -They are educating tire vendor throughout Hawai'i County of their obligation to
charge customers for acceptance and disposal of used tires.
Mr. Goodale wanted to make full disclosure regarding tire education. They had
received a notice of violation regarding tires, and as part of a settlement with the state
they developed the tire program, which communicates to the retailers their obligation to
take used tires. The fee has to be charged regardless. It has produced relatively
beneficial results, but a main task is making sure everyone knows about it.
Green Waste -Greenwaste received in FY 2016-17 in East Hawai'i -over 10,000 tons; in West
Hawai'i - just under 30,000 tons.
9
-The current commercial tipping fee to dispose of Greenwaste is $21.25 per ton,
which is 25% of the current tipping fee. There is no charge for residential
customers
Mr. Okinaka asked what the County does with the greenwaste, and Chair Hayducsko
said they contract with HER to grind up greenwaste and create mulch. In East Hawai'i,
they contract to make enhanced mulch which destroys vectors. In West Hawai'i they
don't make enhanced mulch due to the lack of vectors in the mulch. Both sites are
tested for fire ants on a monthly basis.
Reuse Centers -The reuse program helps to ensure usable materials are diverted from the
County landfills.-The Reuse Centers diverted 350.66 tons from the landfill during FY 2016-17
Education and Outreach-The program focuses on educating the community about the value of recycling,
reuse programs and diversion of materials from the County landfills.
Transfer Stations-There are 22 transfer stations island wide-Landfill tonnage for FY 2016-17: South Hilo Sanitary Landfill 72,247 tons (36,291
Commercial, 35,956 County); West Hawai'i Sanitary Landfill 122,915 tons
(78,892 Commercial, 46,023 County)
c.Preliminary Discussion on Goals and Objectives.
Mr. Scharf said it would be great to bench mark where they are today, to provide a
baseline for today as a part of setting goals.
Ms. Adams asked how they are going to scope and update what was done ten years
ago and suggested they compare numbers from ten years ago, which would be
interesting. Would be interesting to compare what those numbers were ten years ago.
Mr. Araujo said he would like to see the cost of Recycling Program contracts, and Ms.
Bell said they would like all available data.
Mr. Okinaka said they should look at new methods, landfill mining -metal, plastics that
can be recycled; devices/containers developed for safe back yard burning; ban fires -
clear out acres and have ban fires. HOW ABOUT: Mr. Okinaka said they should look at
new methods of landfill mining, looking at what metal and plastics can be recycled and
whether there are objects that can be safe for backyard burning. They could clear out
land and have large ban fires.
Mr. Scharf said there is food waste technology that turns food into pig/chicken feed.
10
Chair Hayducsko said he doesn't want anyone to be hesitant to throw out any thoughts
or proposals. As a group it's good to throw out ideas.
Mr. Buklarewicz said the Zero Waste Implementation Plan on the Recycle Hawai'i
website shows that 90% of the plan was adopted into the ISMP.
Chair Hayducsko said the objective is to update the ISWMP, not to rewrite it. They all
want to protect the land and environment. For the schedule, they were thinking of
having monthly meetings, and then completing and submitting the plan to the state by
the end of 2019. There will be draft plans the consultants will present to the SWAC for
review and debate. There is a lot to do.
Mr. Ely expressed concerns about what the consultants would be doing, whether they
would be reporting to the SWAC on a regular basis, and what their timeline was for a
first draft. Mr. Goodale said they could provide the scope of work and what they expect
to get for the money they are paying the consultant. The SWAC will have a lot of
influence over the direction the plan takes. He would arrange to have the consultant
contract available for the SWAC's review.
Mr. Lee explained that he worked for the consultant, and they had been hired to do
basically four tasks: first is the design process--the methodology to determine how they
are going to do the update. The second is to present a preliminary draft. The third task
is to conduct public hearings, and the last is to finalize the draft and submit to the
Department of Health. There is a schedule with detailed tasking, general tasking, and
milestones for each task along with the scope.
d.Discussion on frequency of meetings, best time and day to meet, and
location.
With Mr. Tamas' assistance, the group settled on the second Wednesday of every
month, from1 :00 p.m. to 3:00 p.m. for their regular meetings, or at such other date, time,
and place as may be specified by the SWAC.
Motion and Vote: M§.f. Bell moved to meet on the second Wednesday of every month,
starting on April 11, 2018, from 1 :00 p.m. to 3:00 p.m. in Hilo, unless otherwise noted.
Mr. Scharf seconded the motion, and all members voted aye.
e.Decide on date, time, and location of next meeting.
-See above.

Solid Waste Management Plan ("IRSWMP") update to the Committee
Members
Chair Hayducsko distributed copies to the members who so requested. Ms. Adams said
she would like copies available for members to view at all future meetings.
b.Overview by George Hayducsko of the Diverted and Landfill Tonnage and
the Cost of Recycling Programs.
Chair Hayducsko gave a PowerPoint overview on the percentage and tonnage of
materials managed and diverted from the landfill. He also gave an overview of the cost of the
recycling diversion programs.
The main points of his presentation are summarized below:
•FY 2016-17 Tonnage of Materials Managed
o Landfill: 195,162
o Greenwaste: 40,465
o Other Reuse & Recycling Programs: 19,330
•FY 2016-17 Percentage of Materials Managed
o Landfill: 76%
o Greenwaste: 16%
o Other Reuse & Recycling Programs: 8%
•FY 2016-17 Tonnage of Materials Diverted from the Landfill
o Greenwaste: 40,465
o Metal/Automobiles: 9,075
o Glass: 4,935
o Old Corrugated Cardboard (OCC)/Paper: 3,575
o Plastics (1,2 &5): 1,043
o Reuse Centers: 350
o E-waste: 235
o Household Hazardous Waste: 93
o Used Motor Oil (UMO): 24
•FY 2016-17 Percentage of Materials Diverted from the Landfill
o Greenwaste: 68%
o Metal/Automobiles: 15%
o Glass: 8%
o Old Corrugated Cardboard (OCC)/Paper: 6%
o Plastics (1,2 &5): 2%
o Reuse Centers: 1 %
o E-waste: less than 1 %
o Household Hazardous Waste: less than 1 %
o Used Motor Oil (UMO): less than 1 %
•Diversion Program Contracted Expenses and Cost per Ton (Utilizing FY2016-
l 7 Disposal Report Data)
o Greenwaste Contracted Expenses: $4,205,675
Cost per Ton: $104
o Metal/ Automobiles Contracted Expenses: $945,338
Cost per Ton: $104
o 2-Bin Recycling Contracted Expenses: $1,018,060
Cost per Ton: $170
2
o Reuse Centers Contracted Expenses: $211,209
Cost per Ton: $603
o E-waste Contracted Expenses: $192,071
Cost per Ton: $817
o Household Hazardous Waste Contracted Expenses: $220,406
Cost per Ton: $2,370
o Used Motor Oil (UMO) Contracted Expenses: $25,723
Cost per Ton: $1,072
Ms. Bell asked whether there was a landfill cost per ton, and Mr. Goodale replied that it
cost approximately $145 to put a ton into the landfill.
Vice Chair Okinaka asked whether the contracted expenses discount the fees that are paid
to take things to the landfill, and Chair Hayducsko said no, that it is the cost the County pays to
the contractor. It is the cost to the County.
Mr. Buklarewicz commented that the increase in cost for e-waste went up about 3 cents
per pound. Recycle Hawai'i had pulled in 225 tons in a 12-month period, and it was about 38
cents per pound. This is based on a 3-year average for both East and West Hawai'i.
Ms. Bell said that at some point she would like to know the net prices of greenwaste
minus tip fee. She would like to see the overall cost to determine whether the greenwaste tip fee
is too high or too low. Chair Hayducsko answered he would have that number for the next
meeting.
Mr. Buklarewicz asked whether the Used Motor Oil (UMO) figure includes what is
collected at the Household Hazardous Waste Collection (HHWC) events, or whether it is
separate. Chair Hayducsko said the chart they were looking at shows the UMO collected by both
the DIY UMO vendors, and the UMO collected at the HHWC events is listed under the HHWC
event. Mr. Goodale explained that the County is charged by the gallon for the UMO collected by
the UMO vendor at the UMO volunteer collection sites, and the County is charged primarily a
lump sum for all the waste collected during the HHWC events.
Mr. Okinaka asked how DEM determines the tonnage of greenwaste, and Chair
Hayducsko said there is a scale that weighs all the greenwaste. If the greenwaste comes from a
business, there will be a charge for it. If it comes from a transfer station through the public, it is
weighed but there is no charge.
5.NEW BUSINESS
a.Overview by George Hayducsko of the 2009 IRSWMP
Chair Hayducsko handed out a draft on the status ofHawai'i County's 2009 IRSWMP
and explained that it shows items recommended in that plan and the status of those
recommendations. Some recommendations were implemented, and some were not. The status is
not yet updated on all the recommendations that are listed. As an example, he pointed out a
recommendation to expand and improve public education and awareness. The status shows that
there has been no dedicated public education and awareness program since June 2014.
3
Mr. Buklarewicz commented that education is the most important factor if the population
is to recycle. Chair Hayducsko agreed that education is critical and explained that DEM's
website is maintained, facility tours are provided, and they issue press releases, advertise, and do
presentations. However, they do not have staff to design an education program.
Mr. Scharf asked whether the consultant will be writing a new draft plan or will be
working from the former plan. Mr. Miller explained that this is a great tool to determine how we
implemented the current plan, and a new plan will be produced to follow through.
Vice Chair Okinaka asked whether they would get a breakdown of what was not
implemented from the old plan, and Ms. Adams asked about they would be reevaluating the old
recommendations and solutions. Chair Hayducsko replied that they would be coming up with
ideas, and the ideas will be put in front of staff and the consultants for inclusion into the plan.
b.Overview by George Hayducsko of the 2-Bin Recycling Program
Chair Hayducsko gave a presentation on recyclable materials and explained that having
clean recyclables is always important and highly recommended, and more so now that China and
other Asian countries are allowing very little contamination. There is a lot of contamination,
however, in DEM' s 2-bin recycle bins. HIS items should be recycled at certified redemption
centers rather than be placed into the 2-bin recycling bins.
Plastic containers numbered 1, 2, and 5 are accepted in the 2-bin recycling containers. It
is important for people to look at the number on these containers before putting them into the
bins at the transfer stations. Education is critical.
The County contracts with Business Services Hawai'i (BSH) to collect, transport,
process, and market the recyclables from the 2-bin recycling program. BSH takes the
recyclables back to their facility, where individuals sort out the materials in a sorting line. HIS
glass bottles get shipped intact off the island, as required by the Department of Health. 2-bin
glass gets recycled and used on the island.
County recycling staff inspects that the HIS cans and bottles are labeled properly at both
retail locations and Certified Redemption Centers (CRCs).
Chair Hayducsko announced a short break. Recess was held from I :56 p.m. to 2:02 p.m.,
at which time he called the meeting back to order.
c.Presentation by the Department of Environmental Management's
Consultant regarding the ISWMP Rewrite Methodology
Chair Hayducsko introduced our Dwight Miller, who would be providing the plan outline
and schedule.
Mr. Miller explained that he is with Parametrix and has been in Hawai'i for about 32
years. He worked on Maui's SWMP back in the early 1990s and has worked on miscellaneous
parts of plans since then. He does a lot of solid waste planning as well as a full spectrum of solid
4
waste work in facility planning, design construction, and so on. He said that Chair Hayducsko 's
earlier handout on the recommendations from the 2009 plan and status informs the current
SWAC as they go forward into the 2019 plan. They are essentially learning from the 2009 plan
on what was recommended, how the recommendations were implemented, what could not be
implemented, and then using all that information coming into the new planning effort.
1)Plan Outline
Mr. Miller provided a Power Point of the plan outline and summarized the topics. Several
SW AC members provided comments during the presentation.
•Solid Waste Priorities and Practices with reference to Hawai'i Revised Statutes
Section 342G-2.
o Landfill and Transfer Stations -Support System
o Recyclers require a higher grade of material
•Background on fiscal year 2017 on landfill and waste diversion.
o Solid Waste Annual Reports
o Diversion Incentive Program, where the County used to pay for data. There is
no longer a financial incentive for businesses to provide data.
o Chair Hayducsko said he hopes to ask commercial entities for recycling data.
o Require recyclers to provide recycling data; it takes a really long time for data
to get into the system.
-Ms. Bell said she would like at least the last ten years of annual reports.
•Background on Demographics and Projections
o Project out waste stream
o Increase per capita -population per capita per day in ten years
o County ofHawai'i (COH) population percent change estimate (2010-2017):
8.3%
o State percent change estimate (2010-2017): 5.0 %
o COH projected growth rate (2010-2040): .5%
o State projected growth rate (2010-2040): .8%
•Background on Tourism
o Tourist projection (2015-2040): 7.5 million -just under 10 million
•Summary Status of 2009 Recommendations: What does it mean and what do we see
going forward:
1.Funding constraints
2.Commodity Markets -limited recycling opportunities
3.Tip fees implemented
4.Expanded greenwaste drop-off
5.Enhanced Household Hazardous Waste (HHW) and E-Waste Programs
6.Reconstructing transfer stations -HOVE and Wai'ohinu
5
7.Closing the South Hilo Sanitary Landfill (SHSL ); transferring waste to the
West Hawai'i Sanitary Landfill (WHSL)
•SWAC's Role
o Recommendations utilizing the current status of existing conditions
o Alternatives development
■Doing the planning process for the next ten years
■What more can be done on island? Greenwaste; compost; food waste;
organics; composting programs
-Mr. Scharf suggested pig feed.
-Ms. Adams said she would like to look at a change of technologies and smaller
units.
•Planning Approach
o Involving the SWAC; gathering ideas and how they will work
o Developing a pragmatic plan by implementing recommendations
o Maintaining and implementing the plan
-Ms. Adams recommended bringing in someone from Kaua'i to talk about curbside
pickup. Mr. Goodale agreed it would be good to evaluate curbside service and the
areas where it could be implemented, given the rural nature of the island.
-Mr. Miller added that a 23% diversion rate with a system that does not have
curbside service or mandatory recycling is really great.
•Public Review: DOH review and public to comment
•Public Review and Completion
•Action Items
o Short-Term
■Background
■Field Visits
■Alternatives Development
o Mid-Term
■ISWMP Review and Update
■Interim Draft Review
o Long-Term
■Preliminary Draft Review
■Final Draft Review
■Public Hearings
Mr. Miller explained that the SW AC will bring ideas to the table, and he will be
providing a printout of the methodology, a memorandum, a review of past recommendation, data
collection, infrastructure and human infrastructure, and develop a draft by November. The 6
SW AC will take field trips and have additional meetings. Topics will be reviewed around the
key areas as opposed to working on a chapter at a time.
Mr. Scharf asked Mr. Miller what his best success story was, and Mr. Miller responded
that in Washington, he did a back-to-back plan. It was a very realistic and up front plan, and it
included recycling and facility improvement. He also worked on a study of curbside collection
of recyclables and trash pickup for an urban county.
Mr. Scharf asked Mr. Miller whether it is hard to convince a community to implement
new technology into the infrastructure and whether he had insight on that. Mr. Miller said you
don't want to hang the whole plan on technology. A feasibility study would help to get deeper
on waste characteristics so they would know what they're dealing with.
Chair Hayducsko explained that he had asked the committee members to delete/recycle
the contract that was sent to them earlier via email and replace it with the hard copy provided
today, as the copy sent via email has proprietary information.
Vice Chair Okinaka asked for clarification about the term "update the plan" and whether
it was assumed the former plan is quite solid and the backbone for how solid waste management
will be addressed for the next several decades. Chair Hayducsko said he feels the current SW AC
will help design the best plan they can with today's knowledge. The plan is something that is
never truly finished, as new ways of doing things always come along. They will do their best to
look into the future, figure out what to do, and provide the roadmap.
Mr. Goodale added that a lot of different methodologies have been looked at on disposing
of trash, recycling, and diversion; and the reality is that over the years there has not been a lot of
change. DEM sees the update to the plan as incorporating whatever new technologies would
make sense. Some methodologies have gotten better, and they need to figure out how the
County can do better. No one wants to look at the plan as just maintaining the status quo or
being stagnant. The update is to make it better for the whole County. It is a state mandate for
the plan to be updated every ten years, but the reality is that the plan is looked at and used
frequently by DEM. His copy of the plan is dog-eared and tagged all over. The overall system,
however, can always be improved. He does not want the program to be inflexible or rigid.
2)Schedule
Mr. Miller provided the schedule via PowerPoint and said it would be emailed to the
members.
d.Discuss proposed limited meeting and site visit for June 13, 2018: The
proposed sites to visit on June 13, 2018 are Pahoa Recycling and Transfer
Station, Kea'au Recycling and Transfer Station, Hilo Recycling and Transfer
Station, South Hilo Sanitary Landfill, East Hawai'i Organics Facility and
East Hawai'i Regional Sort Station. Areas of these site visits would be
potentially dangerous to the health and safety of the public and
impracticable for the public to take part in all sections of these site visits, it is
recommended that the Committee approve a limited meeting for the site

ChairHayducsko explainedthatheandMs. Seckel would betag-teaming onthe
variousagenda items.
Ms. Seckel passedouttwohandouts, oneatimeline forthereport andtheother a
workbookforrecommendations and options. Sheexplained thatthe2009planhad
extensive workputintoitandisagoodplan. Sheclarified thatthe SWAC’staskisnot to
createanew plan, buttorevisetheplanwith current andnewinformation. Itwas brought
toherattention thattheprocess needed tomoveforward alittle faster, sothe timelineis
aggressivebut doable, giventhattheyarerevisingtheplanandnotdoingatotalrevamp.
Ms. Seckel saidsheisworkingwith DwightMiller forParametrix. She explained her
background andhistory insolid wasteplanning, andhowit runsinherfamily. Shecreated
theSWACWorkbookforRecommendations andOptions (“workbook), whichis closelytied
tothescheduleandisdesignedtohelpthemembersmakedecisions. The objectiveisto
engage theSWACandCountyinto lookingatoptionsandrecommendations forthe2019
planbystarting with the2009plan. Since themembers have visited thesolidwaste sites
andare savvyonthe currentCounty conditions, theycan focusonoptions and
recommendations.
Sheexplained thatthememberswere being given homework, andtheywouldhave two
weeks to doit. Theyweretolookthroughthe2009planandmakedecisions. Sheprovided
instructions onhowtousetheworkbook, whichincludes eachrecommendation inthe2009plan,
thechaptertofindthem, andthe statusofeach recommendation. Theirhelpisneededto
determinewhethertoretain orremove arecommendation, andprovide contextandtheirown

Several members hadquestionsabouthow tousetheworkbook, andMs. Seckel and
ChairHayducskoprovided answers. Chair Hayducsko saidthatifamember wasinterested only
incertainsectionsoftheplan, he/shecouldconcentrate onthosesections. Theydidnotneed to

Itwasdecided theworkbookneededtobemadefillableso thatmembers could typein

5. NEW BUSINESS
a. Summary byGeorgeHayducsko of theJune13, 2018, andJuly11, 2018,
LimitedMeetings andSiteVisitsanddiscussion regardingfacility conditions.
ChairHayducskobriefly summarized theSWAC’ssitevisits. AttheJunevisittheyspent
some timeatthe landfill itself, receiving anoverviewoftheprocess. Theyalso stopped bythe
sortstation, wherehaulers andbusinesses dumptheir rubbish. Whileremaining inthevan, they
drovebytheorganics facility, theHI-5Redemption Center, andthe2-binrecyclingarea. Then
theyvisited the RecyclingandTransferStation andviewed the system there, andthen
made aquick stopatthe RecyclingandTransferStation.
4
OnJuly11, 2018, theyvisitedthewest side. First theysawtheWest Sanitary
Landfill, whereGreg Goodaleand GeneQuiamas providedan overview. Theythensaw the
West OrganicsFacility, andthenthe Recycling andTransfer Station. They had
lunch atMs. Bell’s home. Their last stopwasattheWaimea RecyclingandTransfer Station,
where amajorissueistheheavy wind.
Heheard fromthemembers thatsignage andeducation areproblems. Signsneed tobe
updated, andmore educationisneeded. TheSWAC’s goalas acommitteeisnot tomicro-
managebutto makesureinformation, suchasthesignageandeducation issues, getsintothe
report.
Hewent aroundthetable andasked eachmember fortheir thoughts fromthesitevisits.
Ms. Bellsaidtherehastobeawaytohavethesecurity guards ortransfer station
attendants helpeducatepeoplewhentheydisposeoftheirtrash. Sheknows thereareunion
issues, but itisnotacceptablewhenshegoestothe TransferStation andseestheworker
justsitting there inhistruck.
Mr. Buklarewicz saidhestill wonderswhy hecan’tbring his usedmotoroil tothe
transferstations.
Mr. Elysaid heusesthe TransferStation frequentlyand wouldsaythatabout a
thirdofthetime, thebinsareoverflowing. Inaddition, thereisanewcontractorhandling the
Reuse Center, andthechangesmadethere have notbeenforthe better. Mainly, itisverymessy.
Ms. Adamssaidshehasthesamecommentsas theothers. Thereisaseparate needfor
education. It iseasiertothrowthings awaythantorecycle. Shewas sorelydisappointedatthe
sortstationinHilo, because thereisalotofcommercial wastethatcouldberecycled. The
signage alsoneedsimproving. Thereneedstobeconstant awarenessandtraining. Peoplejust
don’tknowwhat canandcannot bedone. Management needsto bemoreontopof things. At
theWaimea TransferStation, whichsheuses, itis often overflowing. Pressureneeds tobeput
onthepeoplewhorunthethriftstores.
Mr. Araujosaidheechoeseverybody. Theregional sortstationwasoriginally builtasa
reload stationbeforeMayor Kim’sadministration, andhedoesn’tknowhowitgotchanged. The
Countyneeds betterpersonnelmanagement atthe transferstations, sortstation, andlandfills.
Scrapironand oilstill getdumped. He seescommercial vehicles dumpingtheirloads atthe
transferstations. Therecycleandreuseareas arelikewayward thriftstores, withrusty andopen
containersofpaint. A lotofthe items peopledonate endupinthelandfillbecause theyarenot
storedproperly. TheCounty needsbettercontractswithvendors. Vendorsneedtobeheld to
theirresponsibilities. Thegreenwastesystem, ontheotherhand, isworkingperfectly andisnice
andclean.
ChairHayducskothankedeveryonefortheir comments.

b. Statusofplandevelopment andschedule.
ChairHayducsko said thiswasalreadydiscussed, butifthey hadanyquestions, Ms.
Seckelwastheretohelp. Ms. Bellaskedforclarification onwhentheirworkwouldbedone,
andMs. Seckelanswered thattheSWACistotrytocomplete theirworkinDecember. They
mayneedtomeetagain, depending onthedegreeofcommentsreceivedfromtheDOH.
c. County’sproposed recommendationsdiscussion.
1) Proposed East OrganicsFacility update.
ChairHayducsko asked GeneQuiamas to updatethemonthestatusofthis new project.
Mr. Quiamas saidtheEAis doneandwaitingtobepublished.
ChairHayducsko presentedseveral slides, showing amapoftheproject locationand an
aerialphotograph ofthearea. Healsoshowed slidesofatypicalprocessflowdiagram, a
conceptual siteplan, an “unwindingdevice” andblower unit, andcoveredwindrows. The
proposed siteisonaboutthreeacres attheShipman IndustrialPark. Thefacilityistobeoperated
by Hawaiian EarthRecycling. Theconceptual planhasawastereceivingarea, biofilter, scale,
office, andwindrows. Thecomposting willbeaerobic. Itwillbeaclosed, controlledsystem
andisonthehigh endforcomposting.
Ms. Adamsaskedwhere theorganics willcomefrom, andChairHayducsko saida lotof
thematerialwillbe greenwaste andfoodwaste. Exactlywhere theadditional materialwillcome
fromorhowitwillgettothefacilityhasnotyetbeen identified. Thevendor hastoldthe County
theycanmakecompost withwhattheyhave, buttheCountyshould lookintocapturing
additionaltonnageof organics andhowtocollectandtransporttheorganics.
ChairHayducsko saidiftheSWACis concerned abouthowtheorganicsfacilitywillget
thewaste, theyshould include it inthereport. Does astudy needtobedone tofigureoutwhere
thematerialwill comefrom? Can thefoodbepickedupeveryday? Theseareafewofthe
questions thatcouldbe answered inareport.
Thenext slideshowedtheminimumannualtonnagewhichtheCountyguaranteesto
HERandthetonnage guarantee startingJuly1, 2020.
Ms. Bellasked iftherewasacontractorto buildthefacilityandrunit, andChair
Hayducsko saidtheCountywouldbebuildingit, andtherewouldbeacontractforthe
management andoperation.
Mr. Quiamas saidthedraftEAistobepublished onAugust 23, 2018. Assoonasthe
County receives thefunds, theywillgointothedesign ofthefacility. Thedesignis relatively
simple. Thevendorwillneed togothrough sometestingtoensurethecompostbeing made
meets thecriteria setbytheU.S. CompostingCouncil. Fromthere, theCounty canstarttaking
inmaterialforcomposting. Thedrop-deaddateisJuly1, 2020.

Mr. Araujo askediftheCountybought theparcelfromShipman, andMr. Quiamas said
Shipman’s indications aretheywant tolease. However, everythinghingesontheoutcomeofthe
finalEA. Theland acquisition anddesign cannot becompleted untilthefinalEAisdone.
Mr. Araujosaidthe intersection by ShipmanIndustrial Parkisvery dangerous, anditwill
bebadifthegeneralpublichastogothere. Mr. QuiamassaidtheDOThasaprojecttofundand
signalizethatintersection duringthenextfiscalyear.
2) Newtechnologies.
Chair Hayducskosaidsome members hadasked himtocheck outBioEnergy
Hehas beenplayingphone tagwith GuyKaniho. Hewilltryto getsomeinformationabout the
project andperhapshaveMr. Kanihogive ashortpresentation on it.
Ms. Seckel saidtherearealotofnewtechnologies outthere, buttheyareveryspecific as
tosizeofcommunity, population centers, howmuch wasteisgenerated, andwhatistrying tobe
done. TheSWAC need tonarrow whatthey wanttolookat—arethey lookingtoreduce
greenhousegasemissions? Improvethesorting ofrecyclables? Improve thesorting ofsolid
waste residualsbefore goingtothelandfill? OncetheCommittee identifieswhatneedstobe
improved, thenastudycanbedone.
Ms. Adamsasked ifthewastecharacterizationwasgoingtobeupdated, andChair
Hayducsko saidthereisnoplantodoawastecharacterization studyfortheplan. However, if
theSWACrecommends it, theycanmakethatsuggestion. Ms. Seckel saidtherewasa2008
study referenced inthe2009 plan, andshebelieves itwould have similarresultsnow.
Ms. Adamssaid shewasjustaskingthequestion, asshewonderswhether thingshave
changedenoughtowarrantanotherstudy.
Mr. Araujosaidthatbeingahauler, hefeelshowtonnageis calculatediswrong. Itisthe
volume thatshould matter, nottheweight. Thelandfillisnotgettingtooheavy—it isgettingtoo
full.
ChairHayducsko saidwastecomposition studiesareuseful, butheisconcerned because
theyalways getjustasnapshotofthewaste, whatever wasdumpedinthattimeframe. Thewaste
couldbevery different inanother hour.
Dwight Miller (viaspeakerphone) asked toweigh inonthis. Hesaidawaste
characterizationstudycouldbedone, focusingonthose areasofgreatest interest. Somemajor
demographic and socialchangeshaveoccurredinthe past10 years, particularly withonline
shopping andthepackagingwiththat, andthetypes ofplastics beingused. Astudywould help
getabetterfeelfortherecyclablesthataretogointothevariousfacilitiesbeingproposed. He
would liketodoawaste characterization studyandfocusonthose areas ofparticularinterestto
theCountyandwhere the bestopportunitiesareforpulling materialoutofthelandfill.
7
Mr. Araujosaidbeforeawastecharacterization studyisdone, theymaywanttogoback
andlookat previous studiesdone. Onewasdonebeforetheinitiation ofthetipping fee. The
companythatdidthe studywentthroughandweighedeverything that wentintothelandfill.
Ms. Bellsaidthere wasalsoastudydonein2002.
3) Otherpotentialoptionsofemphasisfor wastediversion: construction and
demolition, cardboard, promotionandeducation.
Ms. Seckel thatfora wastecomposition study, theywouldtryto identifyparticularlow-
hangingfruit. Inlookingatthe 2008study, cardboardwasanitemthatcoulduse abetter
system. Notalltransfer stationshave theoptionofseparatingcardboard, soan ideathatcouldbe
integratedintothe planistoseparatecardboard atallstations.
Thecommittee membersdiscussedideas onhow toimplementhaving cardboard
recycling atallthetransferstations.
Onconstruction anddemolition, Ms. Seckel saiditcouldstayontheisland, asfaras
reusing materialsfrom constructionprojectsinnewprojects—suchasreusing concrete. The
permittingprocesscouldrequire commercial developerstodosomesortofwastereductionplan.
Ithasbecome moreregulated acrossthenation. Therearealotofopportunities toreuseC&D
material onthe island.
Ms. BellwonderedhowC&Dmaterialcouldbereusedontheisland, andMr.
Buklarewiczsaidthere is anOahucompanythatwillbehiringinKonatomarket C&Dmaterial.
Thereis abigmarketforit.
Mr. Miller saidthereissomematerial, suchasdrywall andcleanwood, thatwould have a
strong market incertain locations. Therearedefinitely opportunities to useit. Itisalso better to
usealotof thismaterial, suchas concrete andasphalt, as aninertfillrather thanhaveitgoto a
mixed landfillwhereitisjustmixed inwithother garbage, whichdoesnottakeadvantageofthe
inert characteristics. Whenconstruction companies startidentifyingthematerials theyare
generating, thenmarkets willdevelop withvendorswhowillactuallystartusingthematerial. It
wouldalso begoodtohavepre-demolitionorpre-construction recycling plansforcommercial
projectssothe recyclers outthere canseewhatmaterials willbecome availableand securethem
fortheir recycling facilities. Ifthemessagegetsoutthatmaterials areavailable, markets canbe
developedaroundthem.
Regarding education andoutreach, ChairHayducskoprovidedanoverview onwhatis
beingdonethisyear. Theyhaveabudget todoeducation andoutreach, butitconcernshimthat
notenough isbeingdone. Theycurrently have $85,000budgeted fortheeducation andoutreach
project discussed. Indevelopingtheoutreach, thefirstthing istodecide whatmessage they want
togetoutto thepublic—itneeds to beamessage that reaches peoples’ hearts. Itshould be

3. STATEMENTS FROM THE PUBLIC:
None
4. New BUSINESS:
a. Review and summarize recommendation from the Hawai‘i Department of Health
(DOH).
i. General Comments and Recommendation:
1. Energy-Balance Component. Proposed document handed out to the SWAC;
document will be included in the plan.
2. Facility Implementation Component. Is already in the plan, it just needs to be
labeled appropriately. Parametrix will identify where the component can be found
for the DOH.
3. A Complete Program Funding Component/Capital Improvements. Proposed
documents handed out to the SWAC; documents will be included in the plan.
b. Review and summarize recommendations from ISWMP public hearings and
submitted written testimony.
i. Public Comments – Common Themes:
1. Public Education. Many people interested in expanding the program. This is
probably the comment with the most occurrences.
2. Why not Waste to Energy/New Technologies?
3. Against Waste to Energy (Incineration)
4. Why is the County limiting materials for recycling?
5. Against Pay-As-You Throw, mostly because of illegal dumping.
6. Composting. Want small facilities on other parts of the island, not just Hilo.
Concerns with collection of materials (note: Zero Waste Big Island offered to help
County develop a plan for this.)
7. Waste Composition Study
8. Plastic Recycling Options
9. Reduced Hours at the Transfer Stations.
10. Electronic Recycling
11. Zero Waste
ii. Addressing the ISWMP Public Hearing Comments:
1. Cory Harden (comment 6) Clarification needed – one section of the plan says the
amount of waste generated went down, but another section says it went up.
SWAC recommends that Chair Hayducsko and Parametrix will double
check the numbers for accuracy and amend as needed.
2. Heidi Jaworski (comment 5) Why are Ocean View residents required to put all
drop offs in black plastic trash bags (even cardboard)? This is an added expense
for one of the poorest communities on the island to bear, and is an environmentally
unsound practice. Are we being discriminated against for some reason?
SWAC stated that Ocean View residents are not being discriminated against.
The disposal system in place requires mechanized transfer of trash by
grappling hook from one container to the transport container. For this
system, to prevent littering, it is required that materials be containerized –
whether in a plastic bag or a box.” We recognize a need for an upgrade and
that site is scheduled for modification or upgrades that can be expected in a
few years which would eliminate the need to containerize the trash.
3. Heidi Jaworski (comment 7) In my experience, this is typical of the serious lack of
communication that takes place between county offices and concerned neighbors –
it simply doesn’t exist, and it should. We should be able to work together to make
our communities a better place to live, and responsibly manage the environment
around us.
See Chapter 1 p 1-2 Customer Service: To share aloha and information. The
SWAC will amend the ISWMP to include its position that all public inquiries be
handled with the utmost respect and timely communication.
4. Megan Lamson Leatherman (comment 3) In addition to changing the County code
to allow small businesses to drop off recyclables at recycling and transfer stations
SWAC recommends to add recommendation #84 - Allow non-profit
organizations and community groups to dispose of non-recyclable waste from
coastal cleanups and litter cleanups at Recycling and Transfer Stations
without the need for individual daily transfer station tipping fee waivers and
use permits.
5. Megan Lamson Leatherman (comment 4) In addition to Conduct additional
HHWC events and provide additional locations on island for dropping off more
common HHW items during standard working hours.
SWAC recommends asking reuse center vendor to take certain materials i.e.
household cleaning products (Ajax, soaps, shampoo etc.) with the intent of
diverting them from the HHWCE to the reuse centers. Suggested developing
a list of products and provisions to protect the environment and workers.
6. Lee McIntosh (comment 4) 3.6 – p 3-18 The county should avoid placing
additional burdens on obtaining a building permit.
SWAC comment and recommendation: The waste reduction plan is a
valuable document and the SWAC recommends keeping the recommendation,
and reword to apply to commercial building permits and not to residential
building permits.
7. Paul Montague (comment 1) Page 4-7 The chart indicates that the Ocean View site
recycles glass. It does not.
SWAC recommends to correct that section.
8. Richard Pratt Does the Plan address additional waste resulting from natural
disasters?
SWAC Recommendation: to add a sentence or two in Section 9.4 referring
to the Civil Defense’s Disaster Management Plan for debris management.
Motion and vote: Ms. Adams moves to accept adding in sentence(s) to Chapter 9
referring to Civil Defense; Ms. Bell 2nd the motion and members voted aye.
Motion carries.
9. Dan & Marlene Sabo (comment 1) what is being done to fix the problem of last
minute closures of transfer stations and green waste drop-off sites?
SWAC recommends to add language in the Summary of Chapter 10 - Ensure
County has resources commensurate with the needs of all current and future
solid waste programs (add text as appropriate).
c. Discuss and recommend changes to the ISWMP.
No additional comments.
d. Approve the ISWMP with proposed changes.
Motion and vote: Ms. Bell moved to approve the changes to the ISWMP as discussed
today; Mr. Okinaka 2nd the motion and all members present voted aye. Motion carried.
5. ANNOUNCEMENTS:
Chair Hayducsko thanked the committee members for all their time, effort and commitment.
He also advised that we are not disbanding the SWAC until the ISWMP is approved.
6. ADJOURNMENT:
Motion and vote: Ms. Adams moved to adjourn, Mr. Okinaka 2nd and all members voted
aye.

Considerations for ranking
Diversion Potential – What is the measure’s tonnage diversion potential from landfill?
Local Authority – How much control must the local government exert over the discard management
system (e.g., service providers, infrastructure collection/transfer/disposal, and/or waste generators) in
order to accomplish the measure?
Implied – indirectly through culture or practice – less likely to accomplish measure
Influenced – by policy, permit, license or ordinance – moderately likely to accomplish measure
Explicit - directly through contracts or operations – highly likely to accomplish measure
Receptivity – What is the relative ease and level of effort to initiate and obtain local buy-in for the
measure? For example, does it involve promotional activities, recognition, no requirements on waste
generators, minor costs (generally easier), or does it involve setting mandatory requirements,
restrictions, or higher costs (generally more difficult)?
Environmental outcome – (e.g., ecological toxicity, human heath, greenhouse gas emissions generated
by raw materials extraction and product manufacturing)
Staff Knowledge – How much staff knowledge or specific expertise is needed to implement the
measure? Can it be implemented by mid-level local agency staff without outside legal or contractor
assistance?
Community Led Initiatives – How easy or hard is it for individuals or groups to initiate adoption or
implementation of the measure without actions required by the jurisdiction? Can a local non-profit or
group of interested residents carry out the activity (e.g., develop a “how-to guide”) or will it require
initiation by local jurisdiction staff or elected bodies (e.g., adopt a local ordinance).

SECTION 1
Introduction
The County of Hawai`i is updating its Integrated Solid Waste Management Plan. The plan
will examine waste management options in the County. To aid in the evaluation of these
options, CH2M HILL conducted this waste composition study to provide statistically valid
data on the types and quantities of waste currently being disposed of at the West Hawai`i
(Pu`uanahulu) Landfill. The field work for this study was performed by Sky Valley
Associates.
This report presents the results of the waste composition study, which include composition
estimates, both for the overall waste stream and for the transfer station, commercial, and
self-haul wastes disposed at the landfill. The results are based on samples taken during
May of 2008. A similar study was performed at the South Hilo Landfill in 20011. We have
used the results of that study to represent the composition of waste that enters the East
Hawai`i landfill. The results are combined to provide waste composition estimates for total
County disposal.
There are four major sections of this report. Section 1 briefly summarizes the project,
including a description of the sources of disposed waste and the project methodology.
Sections two through four provide sampling results for the overall waste stream; results for
the transfer station, commercial, and self-haul substreams; and substream estimates for
West Hawai`i and East Hawai`i.
Following the main body of the report are attachments that included detailed sampling
results (Attachments A and B), descriptions of waste components (Attachment C),
descriptions of the sampling methodology and calculations (Attachment D), and field
sampling forms (Attachment E).
1.1 Sources of Disposed Waste
For analysis and planning purposes, landfill disposal quantities can be divided into
substreams. A waste substream is defined according to its source of generation, its means of
collection and transport to the disposal facility, or both2. For the purposes of this study, the
waste disposed at the West Hawai`i Landfill was divided into the following three substream
categories:
1. Transfer Station – This is waste hauled from one of nine transfer stations on the west
side of the Island. It is transported to the West Hawai`i Landfill in transfer station
compactor boxes. Transfer station loads are composed primarily of residential waste.
1 Cascadia Consulting Group, 2001. Waste Composition Study, South Hilo Landfill, County of Hawai`i.
2 It should be noted that this study estimates the composition of waste disposed, not waste generated. Waste generation is
equal to the sum of both the disposed and recycled amounts.
SECTION 1 INTRODUCTION
1-2 APPX B_WASTE COMPOSITION REPORT_121709.DOC
2. Commercial – This is waste hauled by commercial hauling companies. Commercial
haulers use a variety of vehicles to transport this waste to the West Hawai`i Landfill,
including packer trucks (garbage trucks), roll-offs (primarily open boxes), and other
vehicles (e.g. flatbeds, pickups, etc.). This waste is collected both from residences and
businesses.
3. Self-Haul – This is waste that residents, contractors, businesses, and public entities haul
directly to the West Hawai`i Landfill. These loads are transported either in small
vehicles (e.g. autos, pick-ups, etc.) or large vehicles (e.g. dump trucks, flatbeds, etc). As
with waste in the commercial substream, self-haul waste comes from both residences
and businesses. Waste from public agencies (such as the County of Hawai`i Parks
Department) is also included in this category.
The waste stream was broken down further in the transfer station and commercial
substreams as follows:
• During field sampling, samples taken from the transfer station substream were also
recorded by station so that information about the waste composition at individual
stations could be recorded. Note, however, the relatively few number of samples taken
at any individual station make any resulting composition estimates highly uncertain: the
results should be viewed accordingly.
• Samples from the commercial substream were divided among the three main vehicle
types (packers, rolloffs, and other).
Each of the three substreams contributed a portion of the approximately 128,500 total tons of
waste disposed at the West Hawai`i Landfill from July 2007-June 2008 (FY 2008). About 32
percent (or about 41,700 tons) of this waste was hauled from transfer stations. Commercial
hauling companies disposed of nearly 63 percent (81,000 tons), and the remaining 5,900 tons
(approximately 5 percent) were transported to the landfill by self-haulers.
1.2 Methodology
This section presents a summary of the sampling and calculation procedures used in this
study. The complete sampling methodology including descriptions of the main calculations
can be found in Attachment C. The procedures summarized in this section were used
during the recent sampling event at the West Hawai`i Landfill. Sky Valley Associates
conducted both the recent sampling event at the West Hawai`i Landfill and the 2001
sampling event at the South Hilo Landfill; the same procedures were used during both
events.
1.2.1 Sampling Procedures
A sampling plan was developed to produce statistically valid composition data for the three
substreams described above. A total of 100 samples were captured and sorted at the West
Hawai`i Landfill on May 15, 16, and 19 through 21, 20083. The allocation of these samples
among the three substreams was determined according to each substream’s contribution to
3 Because all sampling occurred during May of 2008, these results do not account for any seasonal variation.

the total waste stream, with one exception. There is relatively little mixed self-haul material
delivered to the West Hawai`i Landfill (1,200 of 128,000 tons in FY 2008, or less than
1 percent). Therefore, it was decided that overall sampling accuracy would be improved by
using self-haul sampling results from the 2001 study to represent the composition of mixed
self-haul loads in West Hawai`i, and assigning samples that would have been obtained from
the self-haul stream to the other two substreams. The composition profile of mixed self-haul
loads from the 2001 study was used to estimate the mixed self-haul composition for the
West Hawai`i Landfill.
In addition to the mixed self-haul loads delivered to the West Hawai`i Landfill, there were
about 4,700 tons of pure loads i.e., loads that could be assigned to a single waste component
such as confidential documents or tires (or in the case of construction and demolition debris,
assigned to a subset of the waste stream). The 2001 composition profile was applied only to
the mixed self-haul loads: the pure loads were added to the mixed load profile resulting in a
total self-haul profile.
Finally, adjustments were made so that a sufficient number of samples were taken from
each substream and vehicle type to assure that sample data are representative of
composition. The commercial substream was oversampled to account for the increased
variability typically encountered in that substream.

All loads were systematically selected for sampling4. From each selected load, a 200- to
300-pound representative sample was hand-sorted into 58 prescribed component material
categories, which were then weighed and recorded. Evidence of explosive or hard-to-
process items was noted for each load. A listing and description of the component material
categories is included in Attachment C. Exhibit 1-2 summarizes the number of samples and
the total and average sample weight.
4 Systematic sampling is outlined in more detail in Attachment B. In short, this procedure assures that the correct number of
samples is taken randomly and throughout the day by selecting every “nth” vehicle from each substream (i.e. every 4th
commercial packer truck).

1.2.2 Calculations
A weighted averaging process was used to prepare the waste composition estimates in
which composition percentages from substreams were multiplied by FY 2008 tons from that
substream. The result is FY 2008 tons for each waste component in each substream.
Exhibit 1-3 presents a flow chart that summarizes the calculation process for the waste
composition estimates. For West Hawai`i, composition estimates were calculated for the
sample groups, the three substreams, and the overall waste stream using the linked
procedure shown. For the transfer station substream, composition percentages were
calculated for each of the nine transfer stations. Sample loads that came from each of the
nine stations determined these composition percentages. The percentages were weighted
according to the tons disposed by each station during FY 2008, and then pooled to produce
an overall transfer station composition5.
For the commercial haulers, separate composition percentages were calculated for three
vehicle types: packer, roll-off, and other vehicles. These percentages were weighted
according to the estimated tons disposed by each vehicle type during FY 2008. They were
then combined to give composition percentages for the commercial substream.
For waste from East Hawai`i delivered to the South Hilo Landfill, the waste quantities by
component were determined by multiplying the 2001 waste composition percentages by
FY 2008 deliveries from each substream (transfer stations, commercial loads, and self-haul
loads. As described above, pure loads delivered to the South Hilo Landfill were assigned to
specific waste components.
The overall waste stream composition for West Hawai`i and East Hawai`i was calculated as
an aggregate of the sample group compositions, which were weighted according to their
tonnage contribution to the overall waste stream. Finally, a similar process is used to
combine results from West Hawai`i and East Hawai`i into a total county waste composition
profile.
5 Tonnages from the West Hawai`i Landfill and the South Hilo Landfill provided all tonnages used to “weight” each sample
group for this study. The weighting process is described in Attachment C.

For the West Hawai`i substreams, low and high estimates are shown that represent a
90 percent confidence level, meaning that there is a 90 percent certainty that the actual
composition is within the calculated range6. In exhibits and charts throughout this report,
the values graphed represent the mean component percentage, not the range.
6 The low and high estimates could not be calculated for any profile that blends information from more than one East Hawai`i
substream because the relative quantity of waste delivered to each substream has changed since 2001.

SECTION 2
Countywide Sampling Results
This section presents a summary of countywide composition results for the total waste
stream and the three substreams (transfer stations, commercial, and self-haul), and includes
data for both West and East Hawai`i. Most of this information is presented in one of the
following two formats:
• A bar chart that depicts the composition by nine main waste categories: paper, glass,
metal, plastic, organics, construction and demolition, household hazardous, special, and
mixed.
• An exhibit that lists the ten largest of the 58 waste components, by weight.
More comprehensive exhibits that details the full composition results for the 58 component
categories are presented in Attachment A (Exhibits A-1 through A-6).
2.1 Total County, West Hawai`i, and East Hawai`i Composition
Exhibits 2-1, 2-2, and 2-3 are bar charts that show the overall composition results for the nine
main waste categories of waste disposed for the entire County, for West Hawai`i, and for
East Hawai`i, respectively. When combined, organics and paper comprise more than half of
the waste stream. Construction and demolition waste accounts for another 22% by weight.
The construction and demolition category includes such components as clean lumber and
gypsum scrap. The organics main waste category contains such components as food,
textiles, and prunings.
The composition of waste disposed in West Hawai`i is similar to the composition of
disposed waste in East Hawai`i. Two differences that merit mention include: there are more
organics disposed of in West Hawai`i (35.3%) than in East Hawai`i (29.6%); and more special
waste disposed of in East Hawai`i (5.2%) than in West Hawai`i (1.9%). The types of special
wastes disposed most often in East Hawai`i include industrial sludge, bulky items, and tires
(see Exhibit A-3 in Attachment A).
Exhibits 2-4, 2-5, and 2-6 show the ten largest waste components for the entire County, for
West Hawai`i, and for East Hawai`i. In all three areas, the largest three components by
weight are food, clean and treated lumber7, and cardboard, which combined make up
approximately a third of the total waste stream.
Notable differences between West Hawai`i and East Hawai`i include:
• One component in each area appears on the list in one area but not in the other:
R/C metal8 is in the top ten for West Hawai`i, and film plastic in East Hawai`i.
7 Most of the disposed lumber in the waste stream is treated, and is not appropriate for composting.
8 The R/C components include waste that is made mostly of one component but contains significant amounts of other
components, or waste that is part of a broad waste category but cannot be put into any of its component categories. Examples
of R/C organic waste includes carpet and disposable diapers, while materials such as paper towels and coated milk cartons
belong to R/C paper.
SECTION 2 COUNTYWIDE SAMPLING RESULTS
2-2 APPX B_WASTE COMPOSITION REPORT_121709.DOC
• Clean and treated lumber accounts for 8.8% by weight in West Hawaii versus 14.3% in
East Hawaii.
• Food accounts for 17.7% by weight in West Hawai`i versus 12.8% in East Hawai`i.
Exhibit 2-7 shows a summary comparison of composition and quantities for the nine main
waste categories for West Hawai`i and East Hawai`i.
2.2 Comparison of Hawai`i County Composition to U.S.
Average
Exhibit 2-8 provides an aggregated comparison of the Hawai’i County disposed waste
stream with the U.S. average, as compiled by the US Environmental Protection Agency
(EPA). The data are shown in aggregated form because the EPA data is grouped somewhat
differently and excludes construction and demolition debris. As shown, Hawaii County’s
disposed waste stream includes somewhat more paper, metal, and organics and somewhat
less plastic and glass than U.S. averages.
2.3 Transfer Station, Commercial, and Self-Haul Substreams
Exhibits 2-9, 2-10, and 2-11 are bar charts that show the overall composition results of waste
disposed countywide in the main waste categories for the transfer station, commercial, and
self-haul substreams. The composition by category for transfer station and commercial
substreams are similar with organics, paper, and construction and demolition waste
accounting for 70-80% of the waste disposed. Construction and demolition waste is more
pronounced in the commercial substream (24.0% vs. 14.4%) and organics is more
pronounced in the transfer station substream (37.6% vs. 31.5%). In comparison, the self-haul
substream is quite high in construction and demolition waste (45.6%) and special waste
(21.6%). As shown in Attachment A (Exhibit A-6), most of the self-haul special waste
consists of industrial sludge.
Exhibits 2-12, 2-13, and 2-14 show the ten largest waste components for the transfer station,
commercial, and self-haul substreams. The top ten components make up 69%, 76%, and 87%
of the transfer station, commercial, and self-haul substreams, respectively. Food, clean and
treated lumber, and cardboard are each in the top 5 components in the transfer station and
commercial substreams. The largest self-haul substream components include clean and
treated lumber (20.5%), industrial sludge (15.1%), and green waste (11.4%).
It is important to note that many of the top ten components are good candidates for re-use
or are potentially recyclable. For example, the estimates indicate that there is over
15,800 tons of cardboard disposed by the transfer station and commercial substreams:
cardboard represents 5.9% of the transfer station substream, and 10.0% of the commercial
substream.

2.4 Explosive and Hard-to-Process Items
During the process of capturing and sorting samples, the field supervisor noted loads that
contained hard-to-process or potentially explosive items. Hard-to-process items include
anything that would be difficult or impossible to manually sort, automatically process, or
transfer by conveyor belt due to weight or size constraints. Examples of these items are
appliances, mattresses, and carpet. Of the 100 loads sampled, 9 contained hard-to-process
items: three with mattresses, three with bulky furniture, and one each with large-sized
demolition materials, large crates, and large plastic pipe. Five of the hard-to-process items
came from the transfer station substream and four came from the commercial substream.
No potentially explosive items were identified during the 2008 and 2001 sampling events.

SECTION 3
West Hawai`i Sampling Results
This section presents summary composition results for the West Hawai`i transfer station,
commercial, and self-haul substreams. The information is presented using the same formats
used in Section 2. More comprehensive exhibits that detail the full composition results for
the 58 component categories are presented in Attachment A (Exhibits A-7, A-8, and A-9).
Exhibits 3-1, 3-2, and 3-3 show the overall composition results for waste disposed of in West
Hawai`i via the three substreams. Organics, paper, and construction and demolition debris
account for 77% and 83% of the transfer station and commercial substreams, respectively.
More than 90% of the self-haul substream consists of three waste categories: special waste
(mainly industrial sludge), construction and demolition debris, and organics.
Exhibits 3-4, 3-5, and 3-6 show the ten largest waste components in West Hawai`i for the
three main substreams. Cardboard is a significant component in all three substreams: 5.1%
for transfer stations, 9.8% for commercial, and 2.4% for self-haul. Other components that
appear in all three substreams include food, green waste, clean and treated lumber, and
R/C organic.
Green waste (14.4%) is the largest component of the West Hawai`i transfer station
substream, and food (21.3%) is the largest component of the West Hawai`i commercial
substream. Food, clean and treated lumber and R/C demolition are in the top 5 of both the
transfer station and commercial substreams. Some components that appear in the top 10 of
only one of the transfer station or commercial substreams include R/C metal, ferrous metal,
and textiles, which are in the top 10 in the transfer station substream, and R/C paper,
concrete, and film plastic which are in the top 10 in the commercial substream.
The self-haul substream composition differs from the transfer station and commercial
substreams. The top three components of the self-haul substream are industrial sludge,
clean and treated lumber, and rocks and soil.
Exhibit 3-7 shows FY 2008 tons, the number of samples taken, and composition results by
category for West Hawai`i transfer stations. As discussed in Section 1, the small number of
samples taken from individual stations means that there is considerable uncertainty
associated with these estimates.

SECTION 4
East Hawai`i Sampling Results
This section presents summary composition results for the East Hawai`i transfer station,
commercial, and self-haul substreams. More comprehensive exhibits that detail the full
composition results for the 58 component categories are presented in Attachment A
(Exhibits A-10, A-11, and A-12). As noted in Section 1, the composition percentages for the
East Hawai`i substreams were taken from the results of the 2001 study. The tons for waste
components were calculated by multiplying FY 2008 tons for each substream by the 2001
study’s composition percentages.
Exhibits 4-1, 4-1, and 4-3 show the overall composition results of waste disposed of in East
Hawai`i via the three main substreams. Organics, paper, and construction and demolition
debris account for 69%, 77% and 83% of the transfer station, commercial, and self-haul
substreams, respectively. Other waste types that comprise large percentages of individual
substreams include metal and plastic in the transfer station substream (10.5% and 9.2%,
respectively), plastic in the commercial substream (10.0%), and special waste (14.6%) in the
self-haul substream.
Exhibits 4-4, 4-5, and 4-6 show the ten largest waste components in East Hawai`i for the
three main substreams. Three of the top five components are the same for the transfer
station and commercial substreams (food, cardboard, and R/C paper). Cardboard
comprises 6.8% of the transfer stations substream and 10.5% of the commercial substream.
Several waste components appear in the top 10 of only one substream, including green
waste, bulky items, and R/C plastic, which are in the top 10 in the transfer station
substream, and film plastic, durable plastic, and newspaper which are in the top 10 in the
commercial substream.
The self-haul substream composition differs from the transfer station and commercial
substreams. The top three self-haul substream components are clean and treated lumber,
green waste, and industrial sludge. The only top 10 self-haul components that are also in the
top 10 in one or both of the other substreams include green waste, R/C organic, R/C paper,
and clean and treated lumber.

Sampling Methodology
Objective
This study was intended to produce statistically valid data on the types and quantities of
waste disposed at the West Hawai`i Landfill during FY 2008. The results of this study were
combined with the results of the 2001 study conducted at the South Hilo Landfill resulting
in a waste composition profile for the entire County.
Substream Definition
The waste hauled to the West Hawai`i Landfill can be divided into the following three
categories (called substreams):
1. Transfer Station – is composed of waste hauled from nine transfer stations on the west
side of the island. It is transported to the West Hawai`i Landfill in transfer station compactor
boxes. Transfer station loads are made up primarily of residential waste.
2. Commercial – is composed of waste hauled by commercial hauling companies.
Commercial haulers use a variety of vehicles to transport this waste to the West Hawai`i
Landfill, including: packer trucks (garbage trucks), roll-offs (primarily open boxes), and
other vehicles (e.g. flatbeds, pickups, etc.). This waste is collected from both residences and
businesses. Commercial samples were allocated to each of these three vehicle types.
3. Self-Haul – is composed of waste that residents, contractors, businesses, and public
entities haul directly to the West Hawai`i Landfill. These loads are transported either in
small vehicles (e.g. autos, pick-ups, etc.) or large vehicles (e.g. dump trucks, flatbeds, etc).
As with waste in the commercial substream, self-haul waste comes from both residences
and businesses.
Sample Allocation
The total number of samples allocated to each substream and sampled on each day of the
study is provided in Exhibit D-1. Note that no samples were allocated to the self-haul
substream. There is relatively little mixed self-haul material delivered to the West Hawai`i
Landfill (1,200 of 128,000 tons in FY 2008, or less than 1 percent). Therefore, it was decided
that overall sampling accuracy would be improved by using self-haul sampling results from
the 2001 study to represent the composition of mixed self-haul loads in West Hawai`i, and
assigning samples that would have been obtained from the self-haul stream to the other two
substreams. The composition profile of mixed self-haul loads from the 2001 study was used
to estimate the mixed self-haul composition for the West Hawai`i Landfill.
The project budget allowed for a total of 100 total loads to be sampled. The allocation of
samples between the substreams was determined according to each substream’s

contribution to the total waste stream. Adjustments were made so that a sufficient number
of samples were taken from each substream to ensure a representative composition. Thus,
the commercial substream was slightly over sampled, and the transfer station substream
was slightly under sampled.
Vehicle Selection
Sampling intervals for each substream and vehicle type were determined by dividing the
day’s expected number of arriving loads by the number of samples needed on that day. For
example, if 20 commercial packer trucks were expected to arrive at the West Hawai`i
Landfill on a sampling day, and a total of 5 samples were needed, every 4th commercial
packer truck would be selected for sampling. Prior to each sampling day, the Field
Supervisor was given a sheet outlining specific sampling intervals per substream and
vehicle type. Attachment E contains an example of the vehicle selection sheet used in this
study.
Field Procedures
On each sampling day, the Field Supervisor identified sample loads as they arrived at the
West Hawai`i Landfill. The Supervisor assigned each selected load a unique sample
identification number. Then, the Supervisor surveyed the driver of each vehicle to obtain
“header information” which was recorded on that sample’s waste sort sheet. The following
information was collected for each sample load:
1. Load type
a. Commercially hauled loads only - the hauler name
b. Transfer station loads only - name of transfer station the load came from
ATTACHMENT D SAMPLING METHODOLOGY AND CALCULATIONS
APPX B_WASTE COMPOSITION REPORT_121709.DOC D-3
2. Generator type
a. Commercially hauled loads only
i. Loads that were 80% or more residential waste were recorded as “residential”
ii. Loads that were 80% or more commercial waste were recorded as “commercial”
iii. Otherwise, the generator type was recorded as “mixed”
b. Transfer station loads only - always marked as “mixed”
3. Vehicle type
a. Commercially hauled loads only - recorded as “packer,” “roll-off,” or “other vehicle”
(e.g. flatbeds, dump trucks, pickups).
b. Transfer station loads only - were always recorded as “transfer station box.”
As the load was emptied at the West Hawai`i Landfill, the Field Supervisor observed the
load for evidence of hard-to-process or potentially explosive items. Details regarding these
items were noted on the sample’s waste sort sheet. Hard-to-process items included anything
that would be difficult or impossible to manually sort, automatically process, or transfer by
conveyor belt due to weight or size, such as: appliances, mattresses, cabinets, carpet, asphalt
or concrete, and large pieces of scrap metal or lumber.
Next, the selected load was visually divided into an imaginary 16-cell grid. The supervisor
then identified the randomly selected cell and approximately 200 to 300 pounds of waste
was removed from that cell with a loader and placed on a tarpaulin. Samples were then
tagged with a sample identifier labeled with their unique sample number and the date.
Once the total weight of a sample was recorded, the material was sorted by hand into the 58
prescribed components, placed in plastic laundry baskets, weighed, and recorded. (See
Attachment C for a list and definitions of the components.)
Each sample was sorted by hand to the greatest reasonable level of detail, until no more
than a small amount of homogeneous fines (less than 1 square inch) remained. The goal was
to sort each sample completely into component categories. However, if fines did remain
after sorting, they were weighed and the Supervisor classified them as “mixed residue.”
As the final step in collecting field data, the Supervisor reviewed, completed and organized
the forms from each day’s sampling activity. The Supervisor also prepared data summary
sheets and sampling checklists at the end of each day. Completed data forms were then
transmitted to the Project Manager at CH2M HILL for review and quality control prior to
data entry.
Waste Composition Calculations
The composition estimates represent the ratio of the components’ weight to the total waste
for each noted substream. They are derived by summing each component’s weight across all
of the selected records and dividing by the sum of the total weight of waste, as shown in the
following equation:

c = weight of particular component
w = sum of all component weights

where n = number of selected samples
for j 1 to m
where m = number of components
The low and high, or confidence interval, for this estimate is derived from a nonparametric
statistical technique called the Bootstrap (Efron, B. 1982. The Jackknife, the Bootstrap, and other
Resampling Plans. Society for Industrial and Applied Mathematics). Standard methods of
calculating sample statistics are generally not applicable to waste composition results
because each substream consists of multiple waste components that must sum to one for
each substream. The distribution of these components is a multinomial with unknown
properties. As such, sample statistics other than the sample mean proportions cannot be
calculated using standard parametric techniques without making unappealing assumptions
that would invalidate the results.
The Bootstrap method is a simulation technique that allows the calculation of the variance
and other statistics of a parameter with unknown distributional properties. In this study, the
Bootstrap method was used to calculate the square root of the Bootstrap variance estimates
of each sample mean (henceforth referred to as the standard error). The mean and standard
error were then used to calculate confidence intervals about sample mean estimates.
The upper and lower confidence limits provide the boundaries of an interval within which
we are 90 percent confident that the true mean proportion of a waste type will lie. They
represent the high and low estimates shown in this study.
Upper and lower confidence limits were calculated as follows:
CIu =gSM + (1.645*SEg)
CIl =gSM - (1.645*SEg)
where: CIu = upper confidence limit
CIl = lower confidence limit
gSM = sample mean proportion for waste component g
1.645 = standard normal deviate (two-tailed) at a 0.05 level
ATTACHMENT D SAMPLING METHODOLOGY AND CALCULATIONS
APPX B_WASTE COMPOSITION REPORT_121709.DOC D-5
SEg = standard error for waste component g
The overall waste composition estimates were calculated by performing a weighted average
across the relevant sampling groups. For the transfer station substream, the estimates were
calculated by performing a weighted average based on the tonnage disposed by each
transfer station. For the commercial substream, the estimates were calculated by performing
a weighted average based on the tonnage hauled by each vehicle type. For the self-haul
substream, the estimates were calculated by multiplying total self-haul mixed loads by the
waste component percentages from mixed loads from the 2001 sampling study. To that was
added the tonnages disposed by 18 pure loads. Component percentages were then
calculated based on the tons of mixed material and pure loads for each component.
The weighting percentages that were used to perform the composition calculations are listed
in Exhibit D-2. This information was obtained from scale records at the West Hawai`i
Landfill for FY 2008. The composition estimates for both the overall waste stream and each
substream were applied to the relevant tonnages to estimate the amount of waste disposed
for each component category.
The weighted average for an overall composition estimate is performed as follows:
Oj = ()+++)*()*(*332211jjjrprprp
where:
Oj = overall composition estimate for component j
p = the production of tonnage contributed by the noted sample group
r = ratio of component weight to total waste weight in the noted sample group

Waste was not sampled from the Laupahoehoe, Miloli`i, and Ke`ei transfer stations.
When calculating composite results for the transfer station substream, the tons from
those stations were assumed to have the composition profile of the following stations:
Pa`auilo, Waiea, and Kohala, respectively.

County of Hawaii Draft 2019 ISWM Plan
DOH comments
November 25, 2019
General Comment
The plan lacks an energy-balance component, facility implementation component and a
complete program funding component. The facility implementation and program funding
components are especially important towards making the plan complete.
Specific Comments
Sec. 4.3.1.2, pg. 4-7, paragraph 2. The statement “In FY 2015, the container fee dropped from
1.5 to 1 cent per container resulting in about 68 percent redemption rate…” suggests that the
container fee amount affects the redemption rate is inaccurate. Statute allows the department
to adjust the container fee based on the redemption rate.
Sec. 4.3.1.3, pg. 4-8, paragraph 2. The CRC counts are not accurate and pertain to activity in
other counties. We suggest focusing on the number of CRCs on Hawaii Island.
Sec. 4.3.3.5, pg. 4-13, paragraph 4. The information regarding rates for on-island use and for
remanufacturing is obsolete (and mixes descriptions of ADF and DBC program activities) and
suggest it be removed.
Sec. 4.5.4, pg. 4-21, bullet #1. The term “waste mitigation” seems to be used interchangeably
with “waste reduction” here and throughout the plan document. If these are references to
waste reduction activities, we suggest the uniform use of “waste reduction”. If the mitigation
actions differ from reduction activities the difference should be explained.
Sec. 4.6.1, pg. 4-34. Recommendation to establish a differential tip fee ordinance. Can more
information be included? i.e. potential tiers for the differential tip fee and materials to be
covered.
Sec. 5.5.6, pg. 5-9 to 5-10. The discussion of reducing the toxicity of commercial discards to
the landfill describes the management of hazardous wastes; which are prohibited from both
county landfills. This section should be edited for clarity.
Sec. 6.2.1, pg. 6-1. We recommend editing this section to clearly distinguish between
hazardous wastes and solid wastes; and to clearly explain the household hazardous waste
exemption.
Sec. 6.5.5, pg. 6-10. We note that a solid waste and/or hazardous waste permit may be
required for the activities described in this section. The permitting requirements would be
dependent on the source of the material and type of process to be used at the prospective
facility or facilities.
Sec. 7.2.7., pg. 7-4, paragraph 2. The statement that “…there are no required standard
practices or documentation procedures.” (for medical waste) is incorrect. Hawaii Administrative
Rules Ch. 104.1 “Management of and Disposal of Infectious Waste” is an applicable regulatory
requirement for the storage, transportation, and treatment of infectious waste.
Responses to Hawai'i Department of Health Comments: Integrated Solid Waste Management PlanHDOH Comments provided November 25, 2019Chapter PageLine No Comment ResponseGeneral N/A N/A The plan lacks an energy‐balance component, facility implementation component and a complete program funding component. The facility implementation and program funding components are especially important towards making the plan complete. Prepared Energy Balance Component (Appendix H) and added a table Exhibit 10‐9 that outlines the 10‐year funding projections for the 10‐year planning timeframefor the recommendations identified throughout this Plan. 44‐7 Paragraph 2Sec. 4.3.1.2, pg. 4‐7, paragraph 2. The statement “In FY 2015, the container fee dropped from 1.5 to 1 cent per container resulting in about 68 percent redemption rate…” suggests that the container fee amount affects the redemption rate is inaccurate. Statute allows the department to adjust the container fee based on the redemption rate. Container fee discussion was modified to omit the correlation between container fee and redemption. 44‐8 Paragraph 2Sec. 4.3.1.3, pg. 4‐8, paragraph 2. The CRC counts are not accurate and pertain to activity in other counties. We suggest focusing on the number of CRCs on Hawaii Island.

Response to ‘Arroya’
Mahalo for taking the time to participate in the Integrated Solid Waste Management Plan Update.
Education and Outreach is ranked as the highest priority by the Solid Waste Advisory Committee for the
2019 Integrated Solid Waste Management Plan Update. A documentary would fall under this category.
Response to Austin, Chuck
Mahalo for taking the time to participate in the Integrated Solid Waste Management Plan (Plan) Update.
The process you described is the strategy used in the update of the Plan. Please see the Executive
Summary, ES1-ES4.
Response to Balsis Jr., Bernard
Mahalo for taking the time to participate in the Integrated Solid Waste Management Plan Update.
1. Since the current cessation of accepting plastics, mixed paper, and newspaper in the County’s
recycling program, it is estimated that the increase in volume by weight to the landfill is
between 1.0 to 1.5 percent per year. With increasing cardboard recovery as well as continuing
waste reduction and reuse through education, the County is hopeful that the overall net will be
zero increase to the landfill.
2. The County and the Solid Waste Advisory Committee evaluate programs using several goals.
One is that they are Efficient and Affordable, i.e. to balance funds available for managing solid
waste with other County priorities, the Plan identifies programs that get the best value (‘bang
for the buck’) for County ratepayers and taxpayers.
3. Please see above number 2.
4. While very limited preliminary research shows that O’ahu may take the residual waste from the
County of Hawai’i, at this time, this is not something the SWAC or the Solid Waste Division has
evaluated as an option.
5. Accepting solid waste from Maui has not been explored at this time. The County will consider
recovery and treatment technology for handling of municipal solid waste if all of the following
criteria are met: 1) waste diversion approaches already in operation are ineffectual or cost
prohibitive in meeting County waste reduction goals, 2) it can be demonstrated that the
technology is environmentally sound and economically feasible, and 3) the technology has a
verifiable and viable commercial track record (minimum of 5 years).
6. The Department of Environmental Management will soon be soliciting Requests for Information
for ideas, innovations, and solutions for entrepreneurs, organizations, public / private
partnerships to provide potential (partial) solutions to these challenges. Entrepreneurs can
contact the County Department of Research and Development to obtain information on
programs relating to agriculture, energy, tourism, economic development, community
development, and film.
Response to Barker, Chuck
Mahalo for taking the time to participate in the Integrated Solid Waste Management Plan Update.
Mahalo for attending the Kona Public Hearing. The County of Hawai’i welcomes any program that, “will
be productive,…, and be a profoundly environmentally-responsible undertaking….internally self-
sustaining and actually makes money.”
Response to Buklarewicz, Paul
Mr. Buklarewicz is a member of the Solid Waste Advisory Committee. His comments were in response to
a member of the public testifying on e-waste.
Response to Cea, Claire
Mahalo for taking the time to participate in the Integrated Solid Waste Management Plan Update.
Currently, the State of Hawaii’s Grant Funding Program falls short of our needs in the County of Hawai’i.
This is addressed in Chapter 6, Recommendation 4: Assess legislative actions that may be necessary to
improve e-waste programs including demanufacturing, storage and handling, and funding equity .
Response to Chang, Jerry
Please see Chapter 9, Section 9.8
Between 2006 and 2014, the County issued several RFPs to vendors who could potentially design,
construct, and operate a waste to energy (WTE) facility. The County’s evaluation of proposals during this
time determined that a mass burn WTE facility was the most commercially and technically feasible
option. The County rejected a proposal in 2008 due to higher than expected costs.
The County will consider recovery and treatment technology for handling of municipal solid waste if all
of the following criteria are met: 1) waste diversion approaches already in operation are ineffectual or
cost prohibitive in meeting County waste reduction goals, 2) it can be demonstrated that the technology
is environmentally sound and economically feasible, and 3) the technology has a verifiable and viable
commercial track record (minimum of 5 years).
Response to Damas, Linda
Mahalo for taking the time to participate in the Integrated Solid Waste Management Plan Update (Plan).
1. Education and Outreach is ranked as the highest priority by the Solid Waste Advisory Committee
for the 2019 Plan. In 2018, before the global changes began to affect our local recyclers and
recycling programs, the County of Hawai’i (County) had just added a Recycling Specialist position
to assist with and expand existing waste diversion programs.
2. Since then, the Recycling / Waste Diversion Section has created collaborative relationships with
new and existing community groups / nonprofits such as Zero Waste Big Island, Recycle Hawai’i,
and Habitat for Humanity ReStore; accepted more invitations and created more opportunities to
interact with the community; is working with the State of Hawaii’s Green Business Program to
expand their program to Hawai’i Island; has sponsored a group of university students working
on a feasibility study of a reusable take-out food service ware program for Hilo; is collaborating
with Zero Waste Big Island on a Master Recycler/Composter program (modeled after Portland,
Oregon’s program); creating social media content; is working to develop a County Facebook
page. Some of these are described in 5.3.1.1 – 5.3.1.7 of the Plan.
3. Local markets are a challenge on Hawai’i Island. Besides the market discussion in Chapter 4, one
small business, Upcycle Hawaii, is successfully capturing plastic film and marine debris for their
products. There is also a grass-roots effort to develop a small cottage-industry for capturing
some of the plastic currently landfilled to make products. Since the program cutbacks of
October 2019, several entrepreneurs have reached out to the County with ideas for plastic
recycling/reuse.
Response to Danks, Mike and Karen
Mahalo for taking the time to participate in the Integrated Solid Waste Management Plan Update.
One of the top recommendations of the Solid Waste Advisory Committee (SWAC) is to develop County
policy and ordinances related to source reduction and recycling.
As discussed in Chapter 3 – Source Reduction, reducing waste is a significant component of the County’s
management plan. The abundance of plastic, its lack of marketability for our island recyclers, and the
increasing presence of it in our oceans, have brought the plastic problem to the forefront.
The County did pass the Plastic Bag Reduction, implemented in 2013 and the Polystyrene Food Service
Ware Ban, which was implemented in 2019.
As this is not a problem specific to the County of Hawai’i, Senate Bill 522, passed last year, to address
this on a state-wide level.
The County of Hawai’i Department of Environmental Management has a representative member in the
State of Hawaii’s Plastic Source Reduction Working Group – whose tasks, per Act 254, are to:
a. Formulate a plan for reducing and recovering plastic from the Hawaii waste stream;
b. Develop strategies to encourage plastic reduction and reuse in the food service industry,
such as reusable container incentive programs for customers;
c. Provide recommendations to encourage reuse, reduction, recycling, and recovery of
waste and create value added products to innovate and responsibly manage the life
cycle of existing resources;
d. Consult with each county that has already enacted ordinances related to single-use
plastics such as plastic bags and polystyrene foam containers and develop
recommendations for the implementation of a uniform, statewide policy for these items
that can replace existing county ordinances and provide businesses with laws that are
consistent throughout the State;
e. Consult with stakeholders to develop appropriate exemptions to address concerns of
health and safety, lack of suitable alternative products on the market, and lack of
infrastructure;
f. Evaluate potential life-cycle and environmental implications of replacing plastic
packaging with alternative products; and
g. Shall submit a report of its findings and recommendations, including recommendations
for pilot projects for Hawaii business to phase out single-use plastic packaging, promote
reuse, and find sustainable alternatives for packaging, as well as any proposed
legislation, to the legislature no later than twenty days prior to the convening of the
regular session of 2021.
All the counties in the State of Hawaii are seeking solutions and we believe that by working together
we can conserve resources and not re-invent the wheel.
Please also see our response to Linda Damas (8) as it describes what we are doing In the County
with respect to education and outreach.
Response to Ernst, Bob
Mahalo for taking the time to participate in the Integrated Solid Waste Management Plan Update.
1. This is addressed in Chapter 4, Section 4.2.1 – the County, in 2007, adopted Resolution 356-07, a
zero waste philosophy toward solid waste management. See also Chapter 3, Section 3.2.2.
Please also see our response to Linda Damas (8) as it describes what collaborations we are
building with local community groups and non-profit groups.
2. To encourage diversion of organics from landfilling, in 2005, the County adopted a differential
tip fee to incentivize the diversion of Greenwaste from the landfill, i.e. tipping fee to drop off
Greenwaste to the mulching facility is 25 percent of the landfill tipping fee. This is a very
successful program. The County continues to collaborate with local community groups and non-
profits to promote community education on composting and other organics diversion.
The County is in the process of completing the planning phase for a Composting Facility in
Kea’au.
3. Although ideal to have recycling receptacles at many more locations, currently the County is
only providing opportunities for recycling on property we own / manage.
As for the volunteer programs, please refer to our Master Recycler program in development.
4. Currently, there are no mandates in place which requires people to recycle. The Solid Waste
Advisory Committee gave high recommendations to 4.3: Expanding opportunities for
commercial recycling and 4.4: Expanding opportunities to recycle in public places and during
public events.
5. Please refer to the Master Recycler program currently in development.
6. Please see response to Mike and Karen Danks (9).
Response to Euaparadorn, Melody
Mahalo for taking the time to participate in the Integrated Solid Waste Management Plan Update (Plan).
1. As noted, Outreach and Education is a top priority of the Solid Waste Advisory Committee
(SWAC). In Exhibit ES-1 of the Plan, Prioritization of Plan Recommendations, Chapter 5.3, notes
to ensure the County has staffing levels commensurate with the needs of the public outreach
program. Please see County’s response to Linda Damas (8) for further discussion.
2. As the planning and construction of the County of Hawai’i Composting Facility advances, the
collection of organics will be addressed.
3. Please see the response to Mike and Karen Danks (9).
4. Please see the response to Jerry Chang (7).
Response to Gudgel, Daniel
Mahalo for taking the time to participate in the Integrated Solid Waste Management Plan Update.
Response to Hamilton, Susi
Mahalo for taking the time to participate in the Integrated Solid Waste Management Plan Update.
Please see our responses to Melody Euaparadorn (11) and Cory Harden (14).
Response to Harden, Cory
Mahalo for taking the time to participate in the Integrated Solid Waste Management Plan Update (Plan).
1. The Plan addresses advanced disposal fees – in terms of Extended Producer Responsibility. See
Chapter 3.5.10, and again, 4.5.13. In Exhibit ES-1: Prioritization of Plan Recommendation,
Chapter 3.1 is categorized as a moderate level of priority as prioritized by the Solid Waste
Advisory Committee (SWAC).
2. Please see Section 10.3.1.2 with respect to funding. Although not an environmental tax, funds
are received through tourism tax. See also response to Danks, Mike and Karen (9).
3. This is one of the top six recommendations of the SWAC, to regularly review and, when
appropriate, renegotiate WHSL contract.
4. One of the top recommendations from the SWAC is to conduct education, outreach, and public
awareness – across most categories. Please also see Section 5.3.1.4. The Master Recycler
Program encompasses much more than recycling; it includes waste reduction education
including the development of “repair cafés” – small community-based huis - where repair
classes / events provide education, and the opportunity to have items repaired for free or a
nominal fee with a social component.
5. The Hawai’i Department of Health (HDOH) does allow for smaller composting facilities,
however, a permit is still required. The County encourages home composting through education
– please see Section 4.3.2.3. The Master Recycler Program addresses not only recycling but
waste reduction and composting as well.
6. You are referencing pounds/day waste generation for years 2007-2008 and 2016-2017. Total
waste generation includes both recyclables and solid waste, not just what goes to the landfill.
We have revised the document to reflect this, both in the paragraph you have identified, and in
Exhibit 2-8 to include pounds/day for both generation and what is landfilled, including further
explanation.
7. Data used was found sufficient to draw conclusions and make recommendations.
8. Please see Section 2.3.1 wherein the Plan discloses that starting in FY2012-13, diversion rates
from the private sector were no longer captured in their entirety. The Division of Solid Waste is
developing strategies to capture the tonnage diverted by entities other than the County.
9. Construction projects and associated health risks go through the County’s permitting processes.
10. Between 2006 and 2014, the County issued several RFPs to vendors who could potentially
design, construct, and operate a waste to energy (WTE) facility. The County’s evaluation of
proposals during this time determined that a mass burn WTE facility was the most commercially
and technically feasible option. The County rejected a proposal in 2008 due to higher than
expected costs. See Exhibit 9-1 Status Update of 2009 Plan Recommendations for Residuals
Management, Section 9.3.4, and Appendix E.
The County will consider recovery and treatment technology for handling of municipal solid
waste if all of the following criteria are met: 1) waste diversion approaches already in operation
are ineffectual or cost prohibitive in meeting County waste reduction goals, 2) it can be
demonstrated that the technology is environmentally sound and economically feasible, and 3)
the technology has a verifiable and viable commercial track record (minimum of 5 years). See
Chapter 9, Section 9.8
11. Pay-As-You-Throw is one of the funding mechanisms the SWAC investigated. Please see Chapter
3 for a dedicated discussion on PAYT options.
12. This is discussed in detail in Chapter 8.
13. The Plan did not address the encouragement of using biodegradable plastics.
14. Please see above response to number 1.
15. Please see response to Claire Cea (6).
Response to Herbst, Donna
Mahalo for taking the time to participate in the Integrated Solid Waste Management Plan Update.
1. Currently, the County is not equipped to collect plastics or any other commodities that are not
being recycled. In Exhibit ES-1: Prioritization of Plan Recommendations, Chapter 4.4 received top
priorities: Expand opportunities to recycle in public areas and during public events.
2. One of the top recommendations from the Solid Waste Advisory Committee (SWAC) is to
conduct education, outreach, and public awareness – across most categories. Specifically
addressing this was Education – to educate Solid Waste Facility Attendants to assist customers
at the recycling area.
Response to Jaworski, Heidi
Mahalo for taking the time to participate in the Integrated Solid Waste Management Plan Update (Plan).
1. The update to the Plan is required by law. Please see Hawaiʻi Revised Statutes Chapter 342G
(HRS 342G).
2. The reduction in the number of recyclable materials currently collected by the County is due to
global market conditions. Please see Chapter 4, Section4.3.3.
3. The last Solid Waste Advisory Committee (SWAC)meeting was held on February 26, 2020. In
Chapter 4, Recommendation 4 includes expanding the number of dropoff locations for green
waste and/or food waste at recycling and transfer stations. Thank the commenter for sharing
the idea.
4. Ocean View Transfer Station hours of operation are every Saturday 7:00 am – 3:00 pm.
5. Ocean View residents are not being discriminated against. The disposal system in place requires
mechanized transfer of trash by grappling hook from one container to the transport container.
For this system, the Hawai’i Department of Health (HDOH) permit requires materials to be
containerized – whether in a plastic bag or a box. For further discussions of the plans for Ocean
View Transfer Station, please see Executive Summary, page ES-3: Since 2009, the County
performed major upgrades to seven recycling and transfer stations—the upgraded facilities are
expected to operate sufficiently through 2029. The County is also in the process of constructing
a permanent recycling and transfer station in Ocean View. Although great progress has been
made, the need to improve facilities with major engineering deficiencies still remains. More
detailed discussions are also in Chapter 8.
6. One of the top recommendations from the SWAC is to conduct education, outreach, and public
awareness – across most categories. Specifically addressing this was Education – to educate
Solid Waste Facility Attendants to assist customers at the recycling area.
7. Comment noted.
8. Increased access to recycling is addressed in Exhibit ES-1. Prioritization of Plan
Recommendations 4.3: Expanding opportunities for commercial recycling, and 4.4: Expanding
opportunities to recycle in public places and during public events. Increased education of facility
attendants is discussed in number 6 above. On-island markets is addressed in Chapter 4, Section
4.3.3. One of the top recommendations from the SWAC is to conduct education, outreach, and
public awareness – across most categories – including bioconversion.
9. Comment noted.

SuggestionJll Sell Scavenging license to the homeless and welfare people. work furlough who desires
extra money.
They are able to make $100 a day.
Need a badge while on the site. No badge . No can enter work area.
You will need some kind of control more than just regulations. Because they fight and all sorts of
things to maintain order.
Suggestion #2 Set up sort stations at the dumpster to educate people how to separate garbage before it
goes into the main sort station.
Suggestion #3 There is a market for rags
Suggestion #4 Maybe can raise pigs on the slop.
Suggestion #5 Furnitures & repairable items can be sold at a reuse station just like Salvation Army this
can be runned by the workers for their income. When people move or die they throw away lots of
good stuff. Stores throw out expired stuff, many still good items that cannot sell. You will get
resistance from stores on this one.
Suggeslion#6 Recycling rubber tires by clipping in liquid nitrogen. This will freeze the rubber so that
you can crush it like glass and separate the steel belt & fabric. I was a I 9 y/o sailor operating a 5,000
lb air compressor on a submarine. Same as on scuba air compressor. 5,000 psi can sub-cool into
cybernetics liquid oxygen & liquid nitrogen This "rubber sand" can be sold as rubber bumpers under
building foundations for earthquake mitigation. Also it now becomes a valuable commodity for resale
to tire companies.
Suggestion #7 Plastics can be heated up and reshaped into different commodities. Recycling can
provide the plastics for this project.
Suggestion # 8 look into hydrogen fuel as a cheap source of heat. & go beyond recycling into
recovery. refurnishing, etc.
Suggestion #9 A $.IO recycle sticker@ the store on as many recyclable items as possible. $.05 go to
the scavenger & $.05 go to shipping it back the manufacture. You made it -you recycle it. Cans,
plastic wraps, any trashy items like advertisement signs & labels. This is a grass roots projects at the
local level. No need nobody's per mission. Just dump it on the company's door step now its your
problem. The recycle sticker will pay the expense. No need legislation for more money.

Response to Kiyuna, Mark
Mahalo for taking the time to participate in the Integrated Solid Waste Management Plan Update (Plan).
1. Scavenging is prohibited – Hawai’i County Code, Section 20-42.
2. As noted, Outreach and Education is a top priority of the Solid Waste Advisory Committee
(SWAC). In Exhibit ES-1 of the Plan, Prioritization of Plan Recommendations, Chapter 5.3, notes
to ensure the County has staffing levels commensurate with the needs of the public outreach
program. Please see County’s response to Linda Damas (8) for further discussion.
3. Please see Exhibit ES-1: Prioritization of Plan Recommendations, Chapter 4.6 – Annually or bi-
annually assess existing local and regional markets for materials across the waste stream; study
service voids for missed opportunities to recover commodities.
4. Please see Exhibit ES-1: Prioritization of Plan Recommendations, Chapter 4, Organics: Develop a
training program and guidance materials for farmers and gardeners.
5. Please see Chapter 3 – Source Reduction. Exhibit 3-2 displays tonnages diverted from landfilling
at Reuse Centers FY 2009-10 to FY 2017-18.
6. Used tires are discussed in detail in Chapter 7 – Special Waste, specifically Section 7.2.8.
7. One of the top recommendations of the SWAC was to: Establish goals that are expressed and
measured in terms of environmental impacts (e.g., greenhouse gas emissions, toxicity, energy
use) and consider full life cycle impacts, in addition to tonnage-based landfill diversion or waste
recovery goals (Chapter 4, Recommendation 5).
8. Please see response to Jerry Chang (7) regarding Waste to Energy (WTE).
9. The Plan addresses advanced disposal fees – in terms of Extended Producer Responsibility. See
Section 3.5.10, and again, Section 4.5.13. In Exhibit ES-1: Prioritization of Plan Recommendation,
a recommendation is Chapter 3.1 with a moderate level of priority from the SWAC.
Response to Kubat, Kristine
Mahalo for taking the time to participate in the Integrated Solid Waste Management Plan Update.
1. The data from the 2008 waste composition study was found sufficient to draw conclusions and
make recommendations.
2. Currently, the State of Hawai’i’s Grant Funding Program falls short of our needs in the County of
Hawai’i. This is addressed in Chapter 6, Recommendation 4: Assess legislative actions that may
be necessary to improve e-waste programs including demanufacturing, storage and handling,
and funding equity (emphasis added).
Response to Leatherman, Megan Lamson
Mahalo for taking the time to participate in the Integrated Solid Waste Management Plan Update (Plan).
1. Yes, this is a 10-year plan, as discussed in the Executive Summary, Chapter 1, Chapter 2, and
elsewhere throughout the Plan. The County will continue to take incremental steps toward
achieving zero waste in the long term with the understanding that the ability to truly achieve
zero waste is realistically challenging for an island. With education, outreach, and public
awareness receiving the highest recommendations, ongoing efforts by the County in
collaboration with community groups will continue to work towards the goals of zero waste
philosophy. The Plan discusses zero waste in the Executive Summary, and notably in Chapter 3,
sections 3.3.2, 3.5.1, 3.5.11; Chapter 4, sections 4.2.1 and 4.5.13; and Chapter 5, sections 5.5.3
and 5.5.5.
2. The recycling contracts are reviewed regularly. The review of WHSL is one of the top six
recommendations of the Solid Waste Advisory Committee (SWAC): to regularly review and,
when appropriate, renegotiate WHSL contract.
3. As describe in Chapter 1, Section 1.1, litter-free is one of the overarching goals used to develop
the Plan: To eliminate illegal dumping on public and private lands, the Plan includes legislation,
education, and outreach programs.
A new recommendation has been added to Chapter 8 To decrease barriers for non-profits and
community organizations, enable them to drop-off non recyclables at transfer stations without
the need for daily waivers or permits.
4. To increase HHW collection on the island, discussions are currently taking place between the
County and the vendor who manages the Reuse Centers regarding accepting limited types of
household hazardous waste.
5. Outreach and Education is a top priority of the SWAC. In Exhibit ES-1 of the ISWMP,
Prioritization of Plan Recommendations, Chapter 5.3, notes to ensure the County has staffing
levels commensurate with the needs of the public outreach program. Please see County’s
response to Linda Damas (8) for further discussion. In addition, the Hawaiʻi Revised Statutes
Chapter 342G (HRS 342G), requires each county to consider solid waste management practices
and processing methods in the following order of priority: 1. Source reduction, 2. Recycling and
bioconversion (including composting), 3. Landfilling and incineration.
6. In prior years, more private recyclers shared their recycling data. Exhibits 2-5 and 2-6 do not
account for non-County-sponsored (private) recycling or diversions. These include big-box stores
(e.g., Costco, Walmart) that ship bales of cardboard and plastic to either the West Coast to
third-party brokers or to the retailer’s distribution center. Contractors or non-profit groups also
sell recycled materials directly to brokers on the mainland. The County hopes to capture this
data in the future for more accurate diversion rates.
7. Pay-As-You-Throw (PAYT) is one of the funding mechanisms the SWAC investigated. Please see
Chapter 3 for a dedicated discussion on PAYT options.
Response to McIntosh, Lee
Mahalo for taking the time to participate in the Integrated Solid Waste Management Plan Update.
1. These waste reduction options are listed as alternatives used by others.
2. Pay-As-You-Throw (PAYT) is one of the funding mechanisms the Solid Waste Advisory
Committee (SWAC) investigated. Please see Chapter 3 for a dedicated discussion on PAYT
options.
3. No island-wide or large-scale curbside recycling program is currently implemented in the
County; however, several companies offer collection of trash in limited areas of the County for
both business and residential customers. In addition to trash service, a few haulers are also
providing recycling collection service to their customers.
4. Chapter 3, Recommendation 1 has been amended to remove “residential building permit.”
5. The County and the SWAC evaluate programs using several goals. One is that they are Efficient
and Affordable, i.e. to balance funds available for managing solid waste with other County
priorities, the Plan identifies programs that get the best value (‘bang for the buck’) for County
ratepayers and taxpayers. Please see Chapter 1, Section 1.1.
6. Scavenging is prohibited – Hawai’i County Code, Section 20-42.
7. Used tires are discussed in detail in Chapter 7 – Special Waste, specifically 7.2.8.
8. Please see response to Jerry Chang (7) regarding Waste to Energy(WTE).
9. One of the top recommendations from the SWAC is to: conduct additional household hazardous
waste collection events (Chapter 6, Recommendation 5).
10. Currently, the State of Hawaii’s Grant Funding Program falls short of our needs in the County of
Hawai’i. This is addressed in Chapter 6, Recommendation 4: Assess legislative actions that may
be necessary to improve e-waste programs including demanufacturing, storage and handling,
and funding equity (emphasis added).
11. One of the SWAC’s top six recommendations is to change County code to allow small businesses
to drop off recyclables at recycling and transfer stations (Chapter 8, Recommendation 5).
Response to Myoshi, Harlan
Mahalo for taking the time to participate in the Integrated Solid Waste Management Plan Update.
Although this technology was not specifically reviewed by the Solid Waste Advisory Committee (SWAC),
the County of Hawai’i is always interested in new technologies. The presentation you provided is
available to the SWAC for their review.
Please see Chapter 9, Section 9.8: the County will consider recovery and treatment technology for
handling of municipal solid waste if all of the following criteria are met: 1) waste diversion approaches
already in operation are ineffectual or cost prohibitive in meeting County waste reduction goals, 2) it can
be demonstrated that the technology is environmentally sound and economically feasible, and 3) the
technology has a verifiable and viable commercial track record (minimum of 5 years).
Response to Montague, Paul
Mahalo for taking the time to participate in the Integrated Solid Waste Management Plan Update (Plan).
1. The County and Solid Waste Advisory Committee (SWAC)will review this and make appropriate
change regarding Ocean View.
2. Please see Chapter 1 – page 1-2. The County and the SWAC evaluate programs using several
goals. One is that they are Efficient and Affordable, i.e. to balance funds available for managing
solid waste with other County priorities, the Plan identifies programs that get the best value
(‘bang for the buck’) for County ratepayers and taxpayers. Currently, the Ocean View hours of
operation are 7:00 a.m. to 3:00 p.m. on Saturdays. This may change in the future as the
programs are reassessed.

Response to Pratt, Richard
Mahalo for taking the time to participate in the Integrated Solid Waste Management Plan Update.
As shown on Exhibit 9-3, the West Hawai’i Sanitary Landfill has a disaster debris processing area.
Disaster planning is mentioned in Chapter 5.5.6: County education staff could collaborate with other
agencies that interact with businesses about environmental issues such as air, energy, water,
wastewater, and disaster planning to leverage resources and avoid duplication of effort.
The Plan has been updated to further address the additional waste and debris for natural disasters in
Chapter 9, Section 9.4.
Response to Sabo, Dan & Marlene
Mahalo for taking the time to participate in the Integrated Solid Waste Management Plan Update.
1. The SWAC recommends the Division has adequate resources commensurate with the needs of
all current and future programs. Language was added to Chapter 10, Section 10.6 of the Plan.
2. The County of Hawai’i has unique geographical characteristics when compared with the other
counties in the State of Hawaii. Our solid waste and waste diversion programs are unique to this
island.
3. Currently the two-bin program has been cut to cardboard and non Hi-5 container glass. The
scrap metal recycler has allowed the County to accept metals in the existing scrap metal
locations. Details like these are reviewed and addressed at the appropriate times.
4. Between 2006 and 2014, the County issued several RFPs to vendors who could potentially
design, construct, and operate a waste to energy (WTE) facility. The County’s evaluation of

and technically feasible option. The County rejected a proposal in 2008 due to higher than
expected costs. See Exhibit 9-1 Status Update of 2009 Plan Recommendations for Residuals
Management.
The County will consider recovery and treatment technology (e.g., WTE, pyrolysis, etc.) if: (1)
other waste diversion approaches (e.g., proposed compost facility in Hilo, shipping of market-
driven unrecyclable materials to the City and County of Honolulu) are cost prohibitive, (2) it can
be demonstrated that it is environmentally and economically feasible, and (3) the technology
has a verifiable and viable commercial track record (a minimum of 5-years) for handling
municipal solid waste. See Chapter 9, section 9.8.
5. Please see Exhibit ES-1. Prioritization of Plan Recommendations, Chapter 9.4: engage in dialog
with the State/Counties about joint solutions (e.g., Discuss with City and County of Honolulu, the
shipping of market-driven unrecyclable materials to their H-Power WTE plant). See also Chapter
9 at 9.6.1.1.
Response to Scharf, Adam
Mr. Scharf is a member of the Solid Waste Advisory Committee (SWAC). Pages one and two of his
remarks were as that of a SWAC member. Pages three and four reflect testimony as a citizen.
Response to Stone, Monica
Mahalo for taking the time to participate in the Integrated Solid Waste Management Plan Update (Plan).
1. The County encourages home composting. The Master Recycler Program addresses not only
recycling but also waste reduction, reuse of resources as well as composting. The Hawai’i
Department of Health (HDOH) does allow for smaller composting facilities, however, permitting
is required. Please see Exhibit ES-1: Prioritization of Plan Recommendation: Chapter 4.1
Organics – Landfill organics ban implementation study.
2. Please see response to Mike and Karen Danks (9). Most aspects of a refillable container
program are regulated by the HDOH at the state level. The Plan addresses advanced disposal
fees – in terms of Extended Producer Responsibility. See Chapter 3, Section 3.5.10, and again,
Chapter 4, Section 4.5.13. In Exhibit ES-1: Prioritization of Plan Recommendation, a
recommendation is Chapter 3.1 with a moderate level of priority from the Solid Waste Advisory
Committee (SWAC).
3. Pay-As-You-Throw (PAYT) is one of the funding mechanisms the SWAC investigated. Please see
Chapter 3 for a dedicated discussion on PAYT options.
Between 2006 and 2014, the County issued several RFPs to vendors who could potentially
design, construct, and operate a waste to energy (WTE) facility. The County’s evaluation of
proposals during this time determined that a mass burn WTE facility was the most commercially
and technically feasible option. The County rejected a proposal in 2008 due to higher than
expected costs. See Exhibit 9-1 Status Update of 2009 Plan Recommendations for Residuals
Management, Section 9.3.4 Evaluation of SHSL Capacity Replacement, and Appendix E –
Chronology of County Waste Reduction Technology Procurement.
The County will consider recovery and treatment technology for handling of municipal solid
waste if all of the following criteria are met: 1) waste diversion approaches already in operation
are ineffectual or cost prohibitive in meeting County waste reduction goals, 2) it can be
demonstrated that the technology is environmentally sound and economically feasible, and 3)
the technology has a verifiable and viable commercial track record (minimum of 5 years).
Appendix H
Energy Balance
ENERGY BALANCE
This discussion provides information regarding the energy usage in the County’s existing system
(baseline) with the introduction of a new compost facility and the construction of a C&D reuse and
recycling facility.
ENERGY USE OF THE PROPOSED ISWMP UPDATE
State regulations require that each county develop and maintain a solid waste management plan that
includes an energy balance component. Per HRS Title 19 342G-26(d), the energy balance component of
the plan shall:
Describe the programs by which the county will investigate or incorporate ways of increasing the
energy efficiency of the solid waste management process, including the assessment of energy and
fuel-production options such as composting, anaerobic digestion, acid hydrolysis, production of liquid
fuels, incineration, or a combination thereof.
As discussed in this Plan, the County considered the procurement of a waste reduction facility between
2006 and 2014. During that time, the County issued several RFPs to vendors who could potentially
design, construct, and operate a waste to energy (WTE) facility. The County’s evaluation of proposals
determined that a mass burn WTE facility was the most commercially and technically feasible option.
However, the County rejected ensuing proposals for a WTE facility due to higher than expected costs.
As recommended in Chapter 9, the County will consider recovery and treatment technology (e.g., WTE,
pyrolysis) if: (1) other waste diversion approaches (e.g., proposed compost facility in Hilo, shipping of
market-driven unrecyclable materials to the City and County of Honolulu) are cost prohibitive, (2) it can
be demonstrated that it is environmentally and economically feasible, and (3) the technology has a
verifiable and viable commercial track record (a minimum of 5-years) for handling municipal solid waste.
Because this is a 10-year plan, only those waste management measures that are likely attainable during
this timeframe are integrated into this discussion; therefore, the introduction of waste reduction
technology is not included. If WTE is considered during this 10-year timeframe of this Plan, the County
will perform a comparative analysis of the options looking at several variables including that of energy
use and emissions.
The energy component shall identify and assess:
(1) The amount of energy input, including, but not limited to, electrical power, gasoline, diesel fuel,
coal, natural gas, propane, kerosene, and heating oil, required by the plan for the accomplishment of
collection, recycling, composting, bioconversion, waste handling, disposal, and landfilling;
In FY 2018-19, the primary energy-using activities of the County’s existing solid waste system consists of
operating its network of recycling and transfer stations, and its two landfills. However, with the planned
transition to hauling residuals exclusively to West Hawaiʻi Sanitary Landfill (WHSL), the estimated fuel
use for these components of the County system shown in Exhibit 1 accounts for this transition. As
shown, it is estimated that 560,580 gallons of fuel are used to operate the County’s solid waste system.
Exhibit 1. Estimated Solid Waste System Fuel Use, Fiscal Year 2017-18
System Component Fuel Use (gallons)
Recycling 109,250
Transfer 203,490
West Hawaiʻi Sanitary Landfill (WHSL) 247,8401
Total 560,580
Note: Exhibit 1 is based on the estimated solid waste system fuel use from FY 2007-08 as described in the 2009 Plan and the percent increase in solid waste
generation and disposal generated in 2017-18.
1 Waste hauling estimate includes fuel usage for the transition of residual haul exclusively to WHSL.
(2) The amount of energy produced from the waste, including electricity, natural gas, hydrogen, and
liquid fuels such as ethanol or methanol;
Multiple haulers collect and bale tires and tire parts in the County for shipment to O`ahu for processing
into ground and crumbed materials for use as fuel at the H-Power waste-to-energy (WTE) facility. Used
oil is either collected and recycled or used in an energy recovery facility. Since tires are also shipped to
the West Coast and/or repurposed, and used oil is also collected and recycled with no understanding of
how much of the waste stream is converted to energy, the amount of energy produced from these
waste streams is unknown.
(3) The net energy use or energy production attributable to the solid waste program. Where feasible,
this assessment shall include energy used in the original manufacture of these goods. National
averages of energy consumed may be incorporated in these estimates; and
The Version 15 EPA Waste Reduction Model (WARM) was used to evaluate the energy impact of the
current waste system (data for FY 2017-18) and three scenarios: 1) the addition of the proposed
compost facility that will accept food and yard waste, 2) the construction of a C&D landfill with a sorting
and reuse area, 3) the addition of the compost facility that will accept food and yard waste and the
construction of a C&D landfill with a sorting and reuse area.
The WARM is a planning-level model used to calculate greenhouse gas (GHG) emissions, energy, and
economic impacts for baseline and alternative waste management practices. It helps solid waste
decision makers and planners track energy balances and greenhouse gas emissions associated with
different waste management practices. The WARM model performs a lifecycle analysis for a given waste
system and accounts for many of the processes required to support that waste system, including metric
tons of carbon dioxide equivalent (MTCO2E), energy in millions BTUs (MMBTU), wage impacts, tax
impacts, and labor hours. This analysis emphasizes energy but also describes MTCO2E (GHG emissions)
for each of the three scenarios.
The following inputs were utilized:
• Recycling and disposal quantities for FY 2017-18
• Eight percent (8%) of the FY 2017-18 landfilled waste stream diverted to show an increase in
composting of mixed organics
• Fifty percent (50%) of the FY 2017-18 landfilled C&D waste, as identified in the Waste
Characterization Study, diverted from the landfilled waste stream
• Default mileage
• Moisture conditions at landfill (dry) = < 20”/year
• Batteries and reuse materials were included in mixed recycling (WARM model does not account
for these items)
The following narratives and tables illustrate the change in energy use with each scenario. The
difference in GHG emissions is also described for each.
Scenario 1: Addition of compost facility that will accept food and
yard waste
This scenario uses more energy (5,663 million BTU) compared to baseline conditions for the transport of
organic waste. GHG emissions recovered is the equivalent to 6,621 MTCO2, which translates to
removing annual emissions from 1,406 passenger vehicles and 745,008 gallons of gasoline.

This scenario uses less energy (1,281 million BTU) compared to baseline conditions with the omission of
organic waste and introduction of a C&D landfill with a sorting and reuse area. GHG emissions
recovered is the equivalent to 18,054 MTCO2, which translates to removing annual emissions from 3,833
passenger vehicles and 2,031,451 gallons of gasoline.

Scenario 3: Compost facility that will accept food and yard waste
and the construction of a C&D landfill with a sorting and reuse area.
This scenario uses more energy (4,381 million BTU) compared to baseline conditions, but less than
Scenario 1, which only includes additional composting. GHG emissions recovered is the equivalent to
24,674 MTCO2, which translates to removing annual emissions from 5,239 passenger vehicles and
2,776,460 gallons of gasoline.

(4) Methods by which net energy use may be decreased or net energy or fuels production may be
increased.
As discussed in the Plan, of the 83 total recommendations, one of the top five recommendations identi-
fies that the County will establish goals that are expressed and measured in terms of
environmental impacts (e.g., greenhouse gas emissions, toxicity, energy use) and consider full life-cycle
impacts, in addition to tonnage-based landfill diversion or waste recovery goals as a baseline for future
improvements to the overall system. In response to this, the County expects to prepare an in-depth life-
cycle assessment (LCA) for the capital development, maintenance, and operation of the Hawai’i County
solid waste system. The LCA would follow the recommendations of this Plan for facility development
and operation and evaluate possible changes to the system that could reduce energy and environmental
life-cycle costs. The primary system components that would likely be evaluated using the LCA are:
• Transfer station development and operation (recyclables, compostables, waste)
• Transfer station material haul (recyclables, compostables, waste)
• East Hawai’i facility development and operations (mulch, recyclables, composting, waste)
• East Hawai’i Regional Sort Station – West Hawai’i transfer (haul)
• West Hawai’i facility development and operations (mulch, waste disposal, landfill gas
operations)
• Urban-density residential collection (pick-up, short-haul, transfer)
