Summary: Pyrolysis is a thermochemical conversion platform that converts biomass and plastics into value-added products. This review focuses on understanding the role of different parameters, such as feedstock composition, heating rate, reaction temperature, residence time, feedstock particle size, and type of pyrolysis reactor. It also analyzes the upgradation of bio-oil using physical and catalytic approaches, as well as the synergistic effects of co-pyrolysis and catalytic co-pyrolysis. The review discusses the use of microwave heating and the role of metal oxide and zeolite catalysts in hydrocarbon and oxygenate formation. Future promising approaches include pyrolysis-combustion combination, microwave hybrid heating, and continuous catalytic co-pyrolysis. This review fills the research gap in understanding pyrolysis process parameters and waste valorization using microwave-assisted pyrolysis, co-pyrolysis, and catalytic co-pyrolysis technologies. It also provides insights into the effective utilization of biomass and plastic waste.

Summary: The scarcity of fossils and the environmental problems associated with their production has increased the demand for sustainable alternatives. Microwave-assisted pyrolysis (MAP) of biomass is a highly sustainable and renewable method for producing bio-oil and value-added products. This paper evaluates the parameters influencing MAP yields and suggests the use of Response Surface Methodology (RSM) through the Central Composite Design (CCD) method for optimizing MAP systems. The study highlights the need for a comprehensive investigation of various factors and the construction of an optimized MAP system at the pilot scale for commercialization.

Summary: This study proposes an enhanced microwave-assisted pyrolysis method for woody biomass without catalyst, utilizing the interaction between microwave and needle-shape metal. The results show that the microwave-metal interaction reduces the activation energy value, enhances the generation of bio-gas, improves the graphite degree of bio-char, and reduces the content of aromatic compounds in bio-oil.

Summary: The development of co-pyrolysis of waste plastics and biomass has been a potential solution for the rise in plastic waste production. This process converts waste into valuable resources, such as chemicals and pollutant-absorbing materials. Accurate prediction of product yields is crucial and involves considering feedstock characteristics and pyrolysis conditions. This study used a support vector machine (SVM) to predict pyro-product yields from microwave-assisted co-pyrolysis of biomass and plastics, showing high predictive accuracy.

Summary: This study investigated the fast pyrolysis of banana pseudo-stem (BPS) to determine the optimal conditions for maximum liquid yield, finding that a pyrolysis temperature of 500°C and a residence time of 1.02 s were ideal. Under these conditions, a total liquid yield of 39.4% was achieved, with a high heating value of approximately 5.35 MJ/kg for the BPS liquid obtained. The BPS bio-oil was found to contain common functional groups and chemical compounds related to phenols.

Summary: A novel method for the generation of methylcyclopentenone and pyridone via the modification of a catalyst was proposed. Different reaction temperatures and catalyst types were found to play a crucial role in the formation of the desired products. The use of ZnO-loaded magnesium aluminum spinel as a catalyst significantly increased the yield of methylcyclopentenone and pyridone.
