[en] This report presents assessments of treatment and disposal technologies that appear to be appropriate for use in regional facilities in the Midwest Compact Region. Treatment technologies assessed are: compaction with a supercompactor, incineration, and incineration followed by solidification of the incinerator ash. Disposal technologies assessed are: shallow land burial, considered a baseline for comparison of other technologies, below-ground and above-ground vaults, the earth mounded concrete bunker, improved shallow land burial, modular concrete canister disposal, mined cavities, unlined and lined augered holes. The text indicates that assessment of treatment technologies sometimes depends on the disposal technology that will be used, and vice versa. However, the major thrust of assessments reported here is to evaluate the technologies without defining combinations of treatment and disposal methods. 20 refs
