Environmental and occupational hazard regulations have motivated consideration of several new developments in paint removal technology. Plastic Media Blasting (PMB)/paint wastes consist predominantly of degraded plastic media plus the stripped paint. They are, in general, placed in the category of being characteristically hazardous'' according to the definition in the RCRA Act because of the excess leachability of toxic metals. The objective of the studies described in this paper is the identification and development of optimum methods for treating PMB/paint stripping wastes, particularly the type of such wastes generated by depainting operations performed at Hill Air Force Base. An optimum treatment method would be one which minimizes disposal costs, generally by waste volume reduction, and which results in a nonhazardous solidified product according to the established EPA criteria. The work has progressed in three phases. In Phase 1, the physical properties of the waste material were determined and full range of treatment methods were tested and evaluated. Phase 2 concentrated on a few selected treatments and encapsulation methods. Phase 3, which is currently in its early setup stages, is a demonstration test being conducted at Hill Air Force Base. 6 refs., 3 figs., 4 tabs.
