Optimizing waste plastics and biomass by co- pyrolysis process: a review

Plastic waste from contemporary lifestyles has skyrocketed in recent years. Co-pyrolysis of these waste plastics and solid biomass feedstock combinations can boost fuels and value-added products in a synergistic way. The manufactured goods can be utilized as chemicals and pollutant sorbents to promote sustainable waste management practices. Elemental composition, proximate analysis, and heating value are the main topics of discussion when discussing the properties of distinctive solid feedstock combinations. Using TGA, pyrolyzer, fixed bed reactor, fluidized bedreactor, microwave, and multi-step reactors with GC, MS, and FTIR diagnostics, experimental techniques for co-pyrolysis study are thoroughly examined. Co-pyrolysis of waste plastic and solid biomass mixes is examined for insights into liquid products for chemicals and fuels, as well as yield and composition of gases and solid residues that evolved together with surface properties of the solid residues derived from the chosen configurations. With the addition of waste biomass for improved synergistic effects in waste disposal, the objective was to offer viable and advantageous routes for the clean and effective disposal of plastic waste.
