PCT No. PCT/EP93/00509 Sec. 371 Date Sep. 8, 1994 Sec. 102(e) Date Sep. 8, 1994 PCT Filed Mar. 6, 1993 PCT Pub. No. WO93/17852 PCT Pub. Date Sep. 16, 1993Thermoplastic articles are removed from a mixed waste stream and are sorted by heating the articles along the path of the waste stream to different softening temperatures of the different types of articles before the articles contact the separating bodies which have surface formations that are forced into the softened zones of the thermoplastic article so that the articles are impaled upon the body. The articles are then removed. The force with which the softened articles are impaled is obtained by a support or counterforce member juxtaposed with the separating bodies.
