ABSTRACT:
A scrap recovery system for recovering scrap material from plastic articles such as plastic bottles. The system comprises a hammer mill for breaking the articles into a heterogeneous mixture of chips, a combination separator and sorter for separating the plastic chips from foreign objects and sorting the plastic chips into batches of chips of discrete homogeneous plastic material, a novel melter for melting the batches of homogeneous chips, and a pelletizer for reforming the molten material into solid marketable pellets.
