ABSTRACT OF THE DISCLOSURE Process for pyrolysis of polymeric organic compounds to remove or retrieve them from objects or materials that are substantially unaffected by the applied heat. The steps include heating in a first vacuum chamber to render flowable such polymers as are fusible at a temperature below that at which appreciable degrad- ation is initiated. The fused polymer drops by free fall from the first chamber to a second vacuum chamber in space communicating relation therewith but maintained at a substantially lower temp- erature, where the polymer resolidifies. Upon further heating, polymer remaining in the first chamber is volatilized and withdrawn from the chamber to a water mist scrubber where it is largely trapped. Remaining vapors in the scrubber are drawn through a vapor separator to a vent stack. After the combustible volatiles are removed from the first chamber, air is admitted into the chamber to oxidize any residual carbon ash, leaving only the inorganic residue which is easily removable from the objects or materials that were not affected by the pyrolysis action.
