The simplest of plastic recycling processes involves collecting, sorting, shredding, washing, melting, and pelletizing.The actual particular processes vary based on plastic resin or type of plastic product. Most plastic recycling facilities use the following two-step process: Step One: Sorting plastics automatically or with a manual sort to make sure all the contaminants are removed from the plastic waste stream.Step Two: Melting down plastics directly into a new shape or shredding into flakes then melting down before being finally processed into granulates.
