Summary:Plastics have revolutionized our lives; however, the exponential growth of their usage has led to a global crisis. More sustainable strategies are needed to address this dilemma and transform the plastics economy from a linearity to a circular model. Herein, we systematically summarize the recent progress in renewable energy‐driven plastic conversion strategies, including photocatalysis, electrocatalysis, and their integration. By introducing the significant works, the design principles, mechanisms, and system regulations, we decipher and compare the various aspects of plastic conversion. These approaches show high reactivity and selectivity under environmentally benign conditions and provide alternative reaction pathways for plastic conversion. Plastic upcycling as a chemical feedstock can yield value‐added chemicals and fuels, contributing to the establishment of a sustainable and circular economy. Additionally, several innovations in reaction engineering and system designs are presented. Finally, the challenges and perspectives of sustainable energy‐driven plastic conversion technologies are comprehensively discussed. Plastic waste has caused a global environmental crisis. Compared with the linear approach, a circular and sustainable plastic economy is of more interest. Photo/electro‐catalysis is shows bright prospects for plastic transformation. This review summarizes recent processes of plastic conversion driven by sustainable energy into value‐added chemicals, fuels, or environmentally friendly products.
