On or before March 1, 1994, the Department shall issue a Request for Proposals to establish a pilot wet/dry collection pilot project, serving at least 600 households, to evaluate the feasibility of wet/dry collection systems that divert source separated recyclables and compostable nontoxic organic materials from the residential and commercial waste streams.
     The study shall evaluate both two-stream and three-stream systems using, at a minimum, the following criteria: convenience and effectiveness of different sorting systems, waste diversion potential, compost quality, marketability of end-products, contamination levels, efficiency and cost of various collection systems, and participation levels.
     The pilot project shall include, but need not be limited to, the following materials: newspapers, mixed paper, glass containers, plastic containers, food waste, paper towels, facial tissue, cardboard, and metals. The pilot program shall include promotional materials to discourage residents from collecting their grass clippings.
