<p>Wastes from insulated electrical cables, including plasticized polymeric material and metal conductors are treated with a solvent to extract selectively the plasticizers in the polymeric material and subsequently the deplasticized polymeric material is subjected to cold crushing. The method is particularly advantageous in connection with the recovery of mixed wastes including plasticized polyvinyl halides and olefin polymers, allowing the selective cold crushing of the polyvinyl halides and their recovery.</p> |
