REFUSE TO ENERGY

This report describes a system for recycling refuse that was developed and put into operation by the Union Electric Company in St. Louis, Illinois. The basic process consists of shredding raw refuse in a hammermill and separating it into a light and a heavy fraction. The light fraction is used as a supplementary fuel in suspension-type power plant boilers, which normally burn pulverized coal. The heavy fraction is passed through a magnetic separator and nuggetizer to recover and densify the ferrous metal which is used as a scrap charge in a steel mill. The remaining portion of the heavy fraction is sent to landfill. A flow diagram of the processing plant is presented, along with test and evaluation results. The environmental impacts of the processing and firing of the refuse have not been completely defined, and some equipment problems have been identified. However, in general, the overall performance has been successful. The costs during the test and evaluation period were relatively high, with the estimated combined capital and operating costs averaging $15.49 per ton for the processing plant and $14.05 per ton for the power plant. The per year -- on two shifts -- are $6.18 per ton for the processing plant and $3.79 per ton for the power plant, with no allowances for the value of the refuse fuel and ferrous metal.
