Abstract
Coal is a traditional fuel of currently increasing importance. Approximately 62 million tons of coal ash are produced annually in the United States: 43 million as fly ash, 14 million as bottom ash, and 5 million as slag. Municipal solid waste and sewage sludges have only recently come to be considered as possible fuel supplements, primarily for disposal purposes rather than because of their desirability as energy sources. Municipal solid waste generation now totals about 140 million tons annually, of which about 21 percent is moisture. About 70 percent of the dry solid waste is combustible with an ash content of about 10 percent. Sewage sludge is generated at a rate of over 5 million (dry weight) tons per year with an ash content of over 30 percent. The Bureau of Mines is examining the ash materials from each of these sources for their resource recovery potential. This report provides a summary of the elemental concentrations found and the results of some extraction studies.
