RI 8244 Metals in the Combustible Fraction of Municipal Solid Waste

With the national focus on energy, the combustible fraction of urban refuse is being extensively considered as a fuel supplement for coal in the generation of heat and power. The objective of these analytical studies by the Bureau of Mines was to determine the concentration of major, minor, and trace elements in the combustible fractions collected at various locations in the Bureau's urban refuse recycling pilot plant located at College Park, Md. The samples processed through the plant were submitted by various municipalities that are considering resource recovery as an alternative to landfill or other means of disposal. Twenty-five elements were determined in samples from six geographic areas and were compared with element concentrations found in typical coal samples.
