Abstract: A method for recovering halogenated hydrocarbons (FCH) from synthetic foams wherein halogenated hydrocarbons (FCH) are released from synthetic foam in a hermetically sealed processing chamber and transferred to a gaseous carrier medium of steam. The steam/FCH mixture is removed from the processing chamber and subjected to condensation to remove pure FCH from the condensed water.

Abstract: Waste products, particularly scrap metal, adulterated by organic components, is pyroprocessed by: (1) shredding the adulterated scrap metal into particles having a maximum size of 5 cm.; (2) in a pyrolysis stage operating at a temperature of approximately 550.degree. C. to 600.degree. C. converting the particles into solids and pyrolysis gas; (3) in a mechanical processing stage separating the solids into unadulterated metal and pyrolysis coke; and (4) in a high-temperature gasification stage into which an oxidizing agent and, optionally, metallurgical coke is introduced converting the pyrolysis coke together with pyrolysis gas stemming from the pyrolysis stage into a heating gas free of organic substances.
