Evaluation of Solidification/Stabilization Treatment Processes for Municipal Waste Combustion Residues

摘要

The document provides results of evaluations conducted to determine the effectiveness of several solidification/stabilization (S/S) processes to treat air pollution control (APC) residues, combined ash and bottom ash from the combustion of municipal solid waste. Five different S/S technologies were evaluated. The untreated and treated residues, sampled from a modern state-of-art waste-to-energy plant, were subjected to a series of physical durability and chemical leaching tests. Results were used to provide a side-by-side comparison of the treatment processes and of the treated residue with untreatedresidues. The S/S processes as formulated and tested, generally did not physically decrease the potential for release of contaminants. One process, however, did significally reduce the potential for Pb release as a result of chemical treatment. The report provides information useful in designing and evaluating S/S processes for treating municipal waste combustion (MWC) residue.
