Plastic Media Blasting Waste Treatments

Abstract

Plastic media blasting (PMB) of aircraft and aircraft parts is replacing paint removal by chemicals at many Air Force installations. Plastic media blasting has several advantages over chemical stripping, including waste and cost reductions, and reduction of environmental problems and health hazards. The use of plastic media may result in generation of a hazardous waste, however, as evident by plastic media stripping of F-4 aircraft at Hill AFB. The waste is hazardous due primarily to metal contaminant levels exceeding EPA's Extraction Procedure (EP) Toxicity limits for chromium and, occasionally, cadmium. Potential methods to reduce or eliminate the hazardous waste volume were evaluated in an HQ AFESC research project. This study has identified methods which can be further developed to make plastic media-blasting waste nonhazardous. Keywords: Paint stripping, Paint removal, Waste disposal, Hazardous waste, Incineration, Screen separation, Waste treatment.
