Abstract
The most important thermoplastic is one of the polyethylene terephthalate (PET) individuals from the polyester group. Owing to its excellent physical and chemical properties, it has enormous applications in food and beverage packaging. One of the most effective ways to reduce the quantity of PET wastes is the route of recycling the wastes. Incessant hard work of researchers across the world has acquired incredible upgrades in the techniques involved in PET recycling. This paper reviews (a) the most viable methods that have emerged over the years for concoction reusing of PET with extraordinary accentuation on glycolytic depolymerization of PET with ethylene glycol; (b) the different process and late improvements towards expanding the monomer yield; and (d) effect of new innovations, for example, nanotechnology, on future improvements of compound reusing of PET and utilization of recycled PET in the packaging sector.
