| Summary: | Argonne National Laboratory-East (ANL-E) is evaluating the feasibility of using vitrification to treat mixed wastes. This program is in the process of identifying glass compositions that can be produced from mixed wastes and additives, with an emphasis on maximizing the waste loading in the glass, and the overall waste volume reduction. Preliminary crucible glass studies with surrogate mixed waste streams have produced a glass composition that could be produced in commercially available melters. This same glass composition, spiked with Resource Conservation Recovery Act (RCRA) metals, pass the Toxic Characteristic Leaching Procedure (TCLP) test. Thus, the final waste form is a low-level radioactive waste. Additional crucible melts with actual mixed waste streams are in progress and will define a compositional envelope of acceptable glasses that will eventually be produced during full-scale melter operations. Evaluations of the likely off-gases from vitrification indicate that the primary off-gases produced during vitrification will include compounds of SOₓ, NOₓ and CO₂. These compounds are routinely treated in the off-gas portion of vitrification systems. The composition of the melter feed can be adjusted to control some of the off-gases produced, if necessary. The economics suggest that annual cost savings resulting from volume reduction and conversion of mixed waste to low-level waste may be substantial. |
