ABSTRACT:
A process and apparatus for the continuous pyrolytic decomposition of a feed material having an organic and an inorganic component and recovery of the inorganic component, carbon-free, for reuse in essentially the same material as from which it originally emanated inter alia. The apparatus includes a reactor assembly for receiving and pyrolytically decomposing the organic component of the feed material. The reactor assembly includes a screw-type conveyer assembly wherein the flights which convey the residue through a housing having openings therein to allow gaseous decomposition products to pass therethrough to preclude pressurization of the housing by the decomposition products.
