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.
