Chemical recycling offers help to solve the problem of plastic pollution. Some companies have taken on this task and developed various processes to reintegrate used plastics into the circular economy. Focusing on PET (polyethylene terephthalate) as one of the top three plastics produced worldwide, these processes upcycle plastic waste into virgin grade materials. Filtration technology from BHS-Sonthofen Process Technology plays the key role in the purity of the products from which virgin PET is made.
