This paper reviews the thermal and catalytic pyrolysis of plastic solid waste (PSW) as a sustainable and efficient method to address the environmental and economic challenges posed by plastic waste. Pyrolysis is highlighted for its ability to recover valuable energy and products such as oil and gas, while reducing carbon emissions compared to combustion and gasification. The review covers existing pyrolysis techniques, parameters affecting product yield and selectivity, and the influence of catalysts. It also compares pyrolysis with other thermal and catalytic plastic treatment methods. Key findings include the importance of feedstock type, operational factors like residence time and temperature, and the role of catalysts in enhancing the process. The paper concludes with recommendations for future research and applications of pyrolysis in managing plastic waste.This paper reviews the thermal and catalytic pyrolysis of plastic solid waste (PSW) as a sustainable and efficient method to address the environmental and economic challenges posed by plastic waste.
