• Enzymatic Degradation: Enzymatic degradation, which involves the breakdown of polymers by specific enzymes, is another important biodegradation pathway for CO₂derived polymers. Research has shown that enzymes such as esterases or lipases can effectively degrade polycarbonate-based CO₂ polymers. However, challenges remain in ensuring complete biodegradation under a range of environmental conditions. Further studies are required to optimize enzyme-polymer interactions and improve degradation rates .
