Among polymer wastes, poly(ethylene terephthalate) (PET) is the most important commercial thermoplastic polyester. Less than 30% of total PET production recycled into new products. Therefore, large amounts waste need to be recycled.

Abstract The unmatched applications of plastic commodities are evident from the enormous production, reaching over 400 million tons per year in recent times. Contrastingly, lack proper management leads to a large accumulation waste, majorly including polyolefins and polyesters. Conventional methods possess significant drawbacks like cost‐ineffectiveness greenhouse gas emissions. Over last decade, chemical processes have shown promising potential for but only hold 0.1% share recycling. catalytic offer excellent protocols obtain high‐value liquid fuels, waxes, chemicals waste. This review presents an elaborate discussion on state art reductive upcycling polyolefins, polyesters, mixed initially discusses alarming statistics plastics conventional approaches followed by introduction processes. Further, various recently reported strategies been elaborated detail catalyst deactivation, technoeconomic analysis, life cycle assessment deeper understanding current this research field. Finally, detailed summary along with existing challenges countermeasures is discussed open new avenues waste research.
