Catalytic co-pyrolysis of biomass and plastic wastes over metal-modified HZSM-5: A mini critical review

Abstract The challenges faced by the fossil fuel industry has led to the exploration of biomass-derived fuel. Biomass can be converted to biofuels via pyrolysis and can be paired with plastic waste to improve biofuel yield and quality. This mini review provides concise information on recent advances in pyrolysis, focusing on using waste, specifically agricultural residues and plastic waste, as resources. Next, discussion is made on pyrolysis of biomass and plastic waste, respectively, followed by co-pyrolysis of biomass and plastic waste. Catalytic co-pyrolysis, including zeolite catalysts and metal-modified HZSM-5 is then reviewed. Finally, the future perspective of this research is discussed.
