The disposal of plastic waste is currently one the major global issues affecting environmental balance and mankind. It therefore crucial to turn into value-added products. Thermochemical recycling techniques have been researched extensively generate fuels, monomers, other has determined that pyrolysis an effective method for chemical recycling. Plastic wastes are transformed products including liquid oil, gas, solid residues during thermal breakdown. Low-quality oil gaseous also produced through pyrolysis, which demands a long retention period high temperature. Catalytic helps deal with these problems. To obtain higher quantities fuel in form or varieties catalysts, such as natural zeolite, Y-zeolite, HZSM-5, ZSM-5, FCC, mud, Ca(OH)2, Al2O3, Fe2O3, used. present Perspective aims briefly unveil recent developments catalytic waste. primarily focuses on impact yields composition well their further applications. Also, extensive review techno-economic assessment based capital operating cost, utilization coproducts, fuel, feedstock logistics presented.
