The report compiles available cost and performance characteristics of processes that are, or might be, employed in solid waste recovery and utilization. The information was obtained from operators of existing systems, equipment manufacturers, and selected experts and the study is focused on size reduction, separation, and recovery and utilization. Among the conclusions, it was found that more than two-thirds of size reduction equipment is used primarily on uniform material in industry and is not recommended for direct use on municipal solid waste; with the exception of magnetic separation, the degree to which the separation techniques studied can be adopted in practice is not well established because of the lack of suitable cost and performance data upon which to base evaluations; in the area of recovery and utilization of mixed solid waste, byproduct recovery appears to have greater economic potential than does material salvage.
