PCT No. PCT/EP93/01583 Sec. 371 Date Jan. 20, 1995 Sec. 102(e) Date Jan. 20, 1995 PCT Filed Jun. 22, 1993 PCT Pub. No. WO94/00241 PCT Pub. Date Jan. 6, 1994Process and apparatus for the storing of thermoplastic material from a mixed stream which can contain objects of other thermoplastic materials or other objects. The targeted thermoplastic material has a softening temperature which is below that of other materials in the mixed stream which is fed by a transport device through a heating unit which heats the mixed stream to the softening temperature. In the softened rubbery state of the thermoplastic material it tends to adhere to cutter blades which comminute the thermoplastic material preferentially while the remaining materials are rejected by the blades and remain uncomminuted to accomplish the sorting.
