MINNESOTA The East Central Solid Waste Commission is comprised of Chisago, Isanti, Kanabec, Mille Lacs, and Pine Counties in Minnesota. OSM was selected by the East Central Solid Waste Commission to assist in the procurement of a Materials Recovery and RDF Processing Facility. OSM was responsible for all technical aspects of vendor selection and contract negotiations. Upon termination of discussions with the RDF market, OSM assisted the Commission in procuring a 250 tons per day Materials Recovery and Composting Facility. When constructed, this Composting Facility (in addition to producing compost) will recover recyclable materials such as newsprint, corrugated materials, high density plastics, aluminum, steel cans, and glass using a combination of mechanical and manual processing. Noncompostable material is separated from the organic fraction with the two processing techniques. The organic fraction is then conveyed to the composting building where the aerated static pile method of composting is utilized in an enclosed building. Biological activity is controlled with the use of a reversible aeration and sprinkling system. Temperature and moisture is continuously monitored to provide optimum conditions for the biological process. The compost material is screened to produce two types of compost and to remove any remaining inorganic material. As technical advisor to the Commission, OSM is responsible for all engineering aspects of developing the turn -key project. OSM prepared the RFQ/RFP, evaluated four vendor proposals in terms of technical and conceptual design issues, capital costs, operating and maintenance costs, and life cycle costs. OSM served as the team leader for negotiation of the construction agreement with the selected vendor. OSM prepared a grant funding application for the Office of Waste Management (OWM), environmental assessment worksheet, permit application, and will provide services through acceptance testing and operations including negotiation of an operating agreement with Daneco, Inc., the selected vendor. The Commission received a $2,000,000 grant from the OWM and a solid waste facility permit from the MPCA. OSM is currently monitoring construction which began in September, 1990. The facility will start up in the summer of 1991. Specific tasks completed by OSM for the East Central Materials Recovery and Composting Facility include: ♦ Market Evaluation Prequalification of Vendors ♦ Preparation of Request for Proposals for the Design/Build Project ♦ Evaluation of Proposals and Vendor Selection ♦ Vendor Negotiation/Contracting ♦ Environmental Assessment Worksheet ♦ MPCA Facility Permit ♦ Capital Assistance Grant ♦ Utilities Design ♦ Transfer Station Design ♦ Construction Monitoring ♦ Acceptance Testing (to be completed) SOLID WASTE COMPOSTING FACILITY PRAIRIELAND SOLID WASTE BOARD - TRUMAN MINNESOTA The Prairieland Solid Waste Board is comprised of the Minnesota counties of Martin and Faribault. The Board selected OSM to assist in the feasibility assessment and implementation of a 100 tons per day mixed municipal Solid Waste Composting Facility. Mixed municipal waste, primarily commercial/industrial and residential waste from which source separated recyclables have been removed, are delivered to the facility tipping floor. Processible waste is shredded and ferrous metals are removed. The waste is then screened to remove the small and heavy inorganic fraction and the light, oversized non-compostable fraction. Water is added to the compostable fraction in a mixer prior to being conveyed to the enclosed composting building. Active composting uses the Seres Systems/OTVD proprietary Siloda process. Composting occurs in side- by-side silos through which the Siloda paddle wheel moves through every four days to mix, turn, and aerate the compost as it is transferred to the adjoining silo. The composting process controls are automatic including reversible flow aeration through floor channels in the silos and water addition through the paddle wheel. After approximately four weeks, the compost is conveyed to another building for curing and storage. The mature compost is then shredded and screened prior to distribution to markets. The Facility, which is currently under construction, is expected to begin start- up in March, 1991 and be fully operational by the summer of 1991. The facility will recover ferrous metals and produce a high quality compost product. OSM was responsible for all technical aspects of implementing the project including technical and financial assessment of the facility, site selection, grant funding application, turn -key facility procurement, permit application, and the environmental assessment worksheet. OSM prepared a detailed RFP and evaluated proposals from five vendors. The proposal evaluation focused on technical issues and life cycle cost analyses to compare the proposals on an equal basis.
