Abstract

During the third quarter of 1994 an investigation began at the University of Pittsburgh into the stabilization of metal-laden hazardous wastes using by-products 140from several of the new advanced clean-coal technologies, recently installed at U.S. coal-fired utility and cogeneration plants. The objectives of this program are (1) to provide useful information and data on the ability of these new treatment chemicals to stabilize waste streams of commercial interest, and (2) to demonstrate the performance of several waste/by-product mixtures at commercial scale. The program's goal is the development of a new market for coal combustion byproducts, namely, the enhanced sale of ash by electric utilities and power cogenerators to hazardous waste treaters.
