Processes and requirements for the recovery of plastics from durable goods

A process for recovering a plastic product mixture from ASR or ESR mixtures, the process comprising process steps for processing a first mixture of materials, the process steps comprising:

• (a) providing the first mixture of materials from ASR or ESR;
• (b) sorting said first mixture using DEXRT, XRF, or a combination thereof, to create a first stream comprising a second mixture and at least one additional stream, the additional stream comprising a third mixture comprising BFR, PVC, metals, or a combination thereof;
• (c) reducing a particle size of at least a portion of the first mixture to form a reduced-size mixture;
• (d) separating at least a portion of said reduced-size mixture at a density of approximately 1.0 to isolate a mixture comprising PP, PE, or a combination thereof;
• (e) separating at least a portion of said reduced-size mixture at a density of approximately 1.10 to isolate a mixture comprising ABS, HIPS, and FPP;
• and
• (f) separating at least a portion of said reduced-size mixture at a density of approximately 1.25 to create a higher density fraction comprising highly filled PP, POM, PVC, PBT, PC/PBT, thermosets, or a combination thereof, and to isolate a lower density fraction comprising PC/ABS, PC, PA, or a combination thereof.
