An integrated, automated process for separating and recycling a broad mix of plastic waste material including, without limitation, polyester and polyolefin streams. The process begins by collecting the material. The material is then pre-processed to remove contamination. Next, the material is coarsely shredded, resulting in ground material. The ground material is friction washed to remove further contaminants from the ground material and form cleaned ground material. The cleaned ground material is sink floated to further wash the clean ground material and separate it into polyolefin flakes and polyester remainder. The polyester remainder is dried, yielding polyester flakes. Finally, the polyester flakes are collected. The process eliminates the tradeoffs between recovery and purity that perplex recycling facilities and permits simultaneous handling of polyesters and polyolefins. Also provided are a related center (and an infrastructure including the center) and at least one computer-readable non-transitory storage medium embodying software for performing the process.
An automated process for separating and recycling a broad mix of plastic waste material including, but not limited to, polyolefin and polyester streams, the process comprising:
One or more computer-readable non-transitory storage media embodying software that is operable when executed to:
An integrated process that constitutes recycling facilities and secondary processing centers with enhanced sorting, separating, and processing capabilities, the process comprising:
