In the face of this global pollution crisis, the development of new methods to achieve plastic recycling and upgrading has become a current research hotspot
.
Compared with traditional physical plastic recycling, one of the important advantages of chemical recycling is that it can obtain the quality of the original polymer and a higher plastic recycling rate
.
Physical recycling grinds waste plastics and mixes them with new plastics, causing degradation of the plastics in the process
.
The use of advanced chemical recycling technology can transform difficult-to-recycle plastic products into raw materials with original quality at the molecular level , which can be used to produce various valuable new products

.
At present, chemical recycling is coming fiercely, and it is becoming more and more popular among chemical companies and even auto brand manufacturers.
Many companies are investing in expansion or recycling plants one after another
.
Chemical recycling is expected to turn the tide in the flood of waste plastics, turning hundreds of millions of tons of "white garbage" into treasure
