TYPE OF TECHNOLOGY: Vnlorgn Process -Anaerobic digestion Name of Company: Steinrr?uller Valorgn, represented by lNnste Recovery Systems, inc. Years in Business: Steinmuller Valorgn since 1962; 001/RSI since 1992 Contact Person: Steven 99Aorris Mailing Address: 33655 AO~nrlinspike ®rive, N4onnrch Bench, CA 92629-442>~ Phone: ®ny 99.672.6634 Eve 949.466.3~~r Email: <sn~nwrsi~nol.com> Website: www. wasterecoverysystems. com 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.
