Which type of polymer Cannot be recycled?
The difference in the recyclability of plastic types can be down to how they are made; thermoset plastics contain polymers that form irreversible chemical bonds and cannot be recycled, whereas thermoplastics can be re-melted and re-molded.
Can PVC be recycled?
While current standards do not generally allow for the practice of recycling used pipes into new certified pipes. PVC pipe producers can recycle nearly all production scrap in-house. Since PVC is a thermoplastic PVC pipe can simply be reground, pulverized and returned to the extrusion process to make new pipe.
