Polyvinyl chloride, or PVC, is a plastic known as vinyl that can be obtained in daily use items from bottles to home tiles. The PVC disposal and recycling process is hazardous on different levels due to the chlorine content inherent in the material, as well as a large number of chemical additives used to increase the stability of the material and its various useful properties.
However, there are several methods of PVC recycling at http://www.tecbogroup.com.au/plastic that are used to decompose them completely in an efficient manner. In the upcoming paragraphs, there is a brief discussion about several PVC recycling methods. Let’s have a look at them.

Chemical recycling process:
Chemical recycling methods break down the plastic at the molecular level. This process is potentially useful because chemical separation allows the removal and recovery of chlorine and other toxins.
Chemical recycling requires complex specialized equipment and is more expensive than mechanical recycling. For this reason, this process is less favored for general PVC waste but is an alternative for several materials that are too dirty or spoiled for mechanical PVC recycling.
Mechanical recycling process:
New raw materials can be obtained from scrap PVC through mechanical recycling. This is a process in which plastic is ground into a powder base for new products. This material recycling process does not eliminate PVC toxins, but the addition of new materials can dilute the existing toxicity.
The mechanical recycling process is a common part of the PVC industry in terms of post-industrial waste reuse. The recycling rate of PVC after consumption lags behind due to material extraction costs and chemical composition issues. While mechanical recycling after use is common with other plastics, PVC additives can contaminate mixed batches and affect plant efficiency.
