RECOVERING POLYURETHANE FOAM AND OTHER PLASTICS FROM AUTO-SHREDDER REJECT

A cooperative study was made by the Federal Bureau of Mines and the Ford Motor Co. to investigate the recovery of polyurethane foam and other assorted plastics from the nonmagnetic rejects from automobile shredders. The material used in the study was produced by the shredding of two 1972 Montegos provided by Ford. The proposed flowsheet, as developed by the Bureau, consisted of a combination of screening, water classification, and gravity separation. All of the foam and between 52 and 80 pct of the assorted plastics were recovered. The reclaimed foam concentrates which contained 63 pct foam were hydrolyzed in laboratory tests to produce a potentially reusable liquid mixture of polyether glycol monomers and toluene diamine.
