N®TE: This is an overview for County Council members, Environmental Management
Commissioners, public and news media.

What waste stream components will you process? (glass, metal, plastics, greenwaste, paper
fiber, other)
All components of mixed dVO5V4/ plus sewage sludge
What components of the waste stream will you not process?
Hazardous wastes and construction debris
What percentage of the waste stream will you divert from landfilling?
About ba~®
What is the composition of any residue (in tons and as a percentage of total MSW)?
About 350® of the total consisting ennin0y o~ inert non-recyclable and non-
compostable rnaterinls, such as dirt, ceramics, metals, glass, and plastic.
Is the technology scaleable
Yes, most certainly.
What is the minimum tonnage you can process daily?
No theoretical minimum, but about 50 TP® as a practical minimum.
What is the maximum tonnage you can process daily?
sy replicating digesters the SV system can process any amount of waste. ~
SV plant in Spain is designed with a sorting line to process about 900 TPID of mixed
waste and, after sorting, to process 450 TP® in four digesters.
Capital costs:
From $175 to $230 per ton of annual capacity. Larger plants would be in the
lower part of that range.
Annual operating costs:
From X32.50 to X40.00 per ton of mixed waste processed.
Cost per ton:
The total net operating cost, including the sale of electricity at $0.06/k1Mh,
is $41.45-$53.22 per ton of mixed waste processed. Revenues from the sale of
compost and recyclable materials are not included.
Financing possibilities:
Public or private financing can be arranged based upon nmulti-year contract
to supply n specified quantity of waste to the facility nt determinable prices. The
multi-year contract should be at least 10 years, preferably 20 years.
Acreage needed:
A plant to process 150 TP® (42,900 1°PY) would need about six acres, while a
plant to process 500 TP® (143,000 fi°PY) would need about 15 acres.
Power generated (in MW):
about 125 kVNh of electricity are available for use outside the plant for each
ton of mixed waste processed. For n 150 °fP® plant the generating capacity would
be about 0.6 Adlble, while a 500 TP® plant would have a generating capacity of about
2.0 AA~OV .
Other end products:
T°he products of anaerobic digestion are methane-rich biogas and a high
quality soil amendment (compost). biogas can be used to generate electricity and/or
steam, or, after treatment to remove carbon dioxide, it can be used advantageously
as a motor vehicle fuel. Use of the biogas as a motor vehicle fuel has environmental
and economic advantages. Fossil fuels would be replaced with a renewable fuel and
the cleaner burning methane would reduce air pollution. If diesel powered waste
hauling vehicles are converted to biogas, further reductions in air pollution are
possible be removing diesel fuel particulates from the atmosphere. Compost has a
wide variety of potential uses in landscaping, agriculture, and land reclamation.
Risks:
~°he technology risk is minimal because the process is proven and is guaranteed
by Steinmuller Valorga. economic risks relate to the market price of electricity,
recyclable materials, and compost, which may vary over time.
environmental impacts:
Civil works and construction of facilities will take place at the selected site,
but will be limited to the period of construction.
1Naste hauling vehicles will deliver waste daily to the facility, but the impact
will be no greater than current delivery of waste to landfills, possibly less depending
upon the location of the selected site.
fihe process emits no odors to the atmosphere. fihe plant is enclosed and all
exhaust air is passed through a biofilter to remove odors. firaces of odorous gases
from the digestion process are destroyed when the biogas is burned to generate
electricity and/or steam.
Combustion gases from the engine generator will be emitted to the atmosphere
but are limited in impact by the size of the generators.
~°he facility becomes a source of renewable energy, reducing the use of fossil
fuels.
the amount of waste disposed of in landfills would be reduced by about 65~®.
Conversely, the rate of recycling would increase to about b5~~.
Social impacts:
Depending upon the size of the plant, about 10-20 jobs would be created.
Timeline from acceptance to full operation:
Design and construction usually are accomplished in 18-24 months. ~i he time
required to obtain the necessary permits to build and operate the plant can be
variable, but the permitting process and the engineering process can be carried out
simultaneously.
