Stabilization of DOE hazardous wastes with clean-coal technology by-products

The objective of this research is to evaluate both the long term and short term stabilization of DOE metal-containing hazardous wastes with clean coal technology (CCT) by-products. This work builds directly on a currently funded DOE/METC project with the University of Pittsburgh (prime contractor) in conjunction with Mill Service (a centralized waste treater), and Dravo Lime Corporation. Studies fall into two categories: (1) observation of the ability of CCT to stabilize and solidify characteristic toxic/hazardous metal-laden wastes (and other DOE metal containing wastes) over the near term via conversion of such wastes into a non-hazardous form by means of pozzolanic type reactions with by-products, and; (2) characterization and understanding of the longer term environmental and physical stability of the resultant solidified matrix in terms of potentially time dependent physical and chemical/toxicological leaching characteristics taking place due to slow solid phase crystalline reactions
