The program has the overall objective of identifying environmental impacts which might result from waste-to-energy conversion processes. These processes are categorized, on a generic basis, as: (a) waterwall incinerators; (b) combined firing systems; (c) thermochemical (pyrolysis) processes; (d) hog-fuel boilers; (e) biochemical systems; and (f) advanced combustion systems such as the CPU 400. This report discusses constituents in solid waste primarily with the idea of illustrating the diverse nature of the feedstock used in such systems. Also presented is an environmental impact analysis based on the contribution of each waste-to-energy conversion system to criteria and other major pollutants. Where emission data were lacking, engineering judgment was used to identify probable levels. A simplified methodology for a preliminary environmental assessment is illustrated. An overview of each of the waste-to-energy conversion systems including their pollution potential and applicable control technology is also contained in this document. The status of such systems as well as their locations, capacities and processing steps involved is identified, to the extent possible.
