The depolymerization process does not deteriorate the material, therefore the process can be repeated on the same material as many times needed.
Fremont, CA: As the demand for recycling solution increases, the plastic industry is finding innovative solutions for plastic waste and investing in plastic recycling technologies.
These recycling technologies help find different plastic waste, processing materials with high contamination levels, and removing the need for complicated and costly sorting steps.

Here are five types of advanced recycling methods:
Gasification
The gasification recycling method processes mixed plastic waste together with domestic and bio-waste. It heats materials in high temperatures without oxygen, which creates syngas. Syngas is further used as a carbon source to create base chemicals, starting the value chain of various end-products.

Dissolution takes the solid form of plastic waste and dissolves it in a solvent. After it is dissolved, the process can mechanically and chemically separate contaminants and additives before separating the original polymer from the solvent. The end result is a clean polymer that can be used as a new raw material resin.
Pyrolysis
Pyrolysis uses a thermal cracking process to transform plastic waste to oil, purified, and used as feedstock to produce base chemicals.
Depolymerization
Depolymerization gives the ability to decompress a polymer chain and break it down into the individual building block molecules for separation, purification, and recovery of plastic materials. This final product s a plastic raw material that is almost similar to the material derived from traditional fossil fuels.
The depolymerized material can be utilized for food contact and medical applications. Also, the process does not deteriorate the material, therefore the process can be repeated on the same material as many times needed.
