Integrated Resources & Solid Waste Management Plan Update - Dec 2009

4.0 RECYCLING, BIOCONVERSION, AND MARKETS Compostable bags. Somewhat less convenient than plastic bins and expensive over the long term for households which is likely to lower recovery rates. Bags cost $0.50 to $1.00 per bag. The bags compost well and avoid the contamination issues associated with plastic bags. claims. 4.5.3.1 Service Standards Like curbside collection, it is recommended that any green waste collection program should be a mandatory program for more densely populated single family neighborhoods to increase efficiency and reduce operating costs. Further, it is recommended that the program include rolling carts loaded using semi- automated of fully- automated equipment. 4.5.3.2 Processing Requirements The County currently contracts for green waste processing (into mulch) at sites at the SHSL and the Kealakehe Recycling and Transfer Station, and it is currently in the process of contracting for development and operation of a composting facility at the WHSL. To minimize transportation costs, it would be advantageous to develop another processing facility in the Waimea area. If that facility is developed, there will be sufficient capacity to process the material. However, mulching produces a relatively low value product that is less desirable than compost or soil products made from compost. After the West Hawai'i compost facility is operational, the County should evaluate the costs and benefits of developing a similar facility in East Hawai'i and possibly in the Waimea area. This is recommended regardless of whether or not curbside green waste collection is implemented. 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 should 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. 4 -18 December 2009
