Vendors of solidification/stabilization (S/S) and other technologies are cooperating with the U.S. Environmental Protection Agency's (U.S. EPA's) Office of Research and Development (ORD), Risk Reduction Engineering Laboratory to demonstrate and evaluate the performance of the technologies to treat residues from the combustion of municipal solid waste (MSW). Solidification/Stabilization is being emphasized in the current program. The technology may enhance the environmental performance of the residues when disposed in the land, when used as road bed aggregate, as building blocks, and in the marine environment as reefs or shore erosion control barriers. The program includes four S/S process types: cement, silicate, cement kiln dust and a phosphate based process. Residue types being evaluated are fly ash, bottom ash and combined residues. An array of chemical leaching tests and physical tests are being conducted to characterize the untreated and treated residues. The S/S evaluation program is the first part of ORD's Municipal Solid Waste Innovative Technology Evaluation (MITE) program.
