A process is disclosed for disaggregating waste materials which contain at least partially reusable elements, mainly metals, plastics and cardboard. The waste materials are stirred in water by mechanical forces, large pieces, in particular plastic pieces, are coarsely crushed and soluble elements, in particular cardboard, are dissolved. The metallic elements are separated from the suspension as heavy materials, the remaining coarse solids, in particular plastics, are mechanically separated from the suspension, and the suspended fine solids are separated from the suspension by dewatering.

Process for disaggregating waste materials which contain at least partially reusable elements

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.
