This review aims to address these gaps by examining recent innovations in catalytic systems, polymerization techniques, and strategies for improving the mechanical and biodegradability properties of CO₂-derived polymers. The research on CO₂-based biodegradable polymers holds considerable environmental and economic potential . By transforming CO₂ into sustainable polymers, this research could contribute to reducing plastic pollution, particularly in marine environments, while also advancing the development of a circular economy model. This transition is not only crucial from an environmental standpoint but also presents significant economic opportunities as the demand for sustainable, eco-friendly materials continues to grow across industries .
