Different methods for returning PET into the economic cycle: A review

Polyethylene terephthalate (PET) is a saturated polyester, which is widely utilized in the production of films, bottles, and fibers in terms of its excellent thermal stability, clarity, strength, and moldability. PET waste has increased as the manufacture and consumption of PET bottles have increased. Major environmental and financial problems have resulted from the disposal of PET bottle waste. Both clear PET bottles and colorful PET bottles are recycled using various methods. However, it is possible to recycle PET trash by chemically replicating the monomers, separating them, and creating new PET from them. Here, we review the synthesis, characterization, and different methods for PET recycling as well as the commercial exploitation associated with the recycling and re-use of them.
