Plastic recycling is a well-established industry that globally processes and resells several million tons of used plastic material each year. Rather than operating merely out of environmental necessity, plastic material recovery services can be both cost-efficient and productive, saving resources for a range of different manufacturing applications. The recycling and reclamation field also encompasses the industrial processes by which plastic materials are separated into their base monomers and made available for further polymerization at secondary and tertiary levels.

While the plastic recycling industry was originally focused on recovering manufacturing scraps and byproducts left over from initial plastic fabrication, present-day recycling services are capable of reclaiming heterogeneous post-consumer goods as well. The methods employed by material recovery systems tend to vary according to the type of plastic being processed, but there are some essential practices common to most recycling services. Stages such as sorting, cleaning, size reduction, separation, and pelletizing can be found in most plastic recycling operations. Likewise, the machinery used to achieve these processes generally falls into a handful of equipment categories called Plastics Recycling Machine.

Plastic Recycling Sorting Process and Equipment
Sorting and grouping plastic materials according to resin type is an important first step in the recycling process because contamination can render a batch of material un-reusable. The most frequently recycled resins, including polyethylene terephthalate (PET), high-density polyethylene (HDPE), and polyvinyl chloride (PVC), must be carefully separated from one another in order to enable further processing. Contaminants within each type of plastic must also be removed from the base resin to ensure stock purity.
