Studies have demonstrated that CO₂-based polymers, such as polycarbonates and polyurethanes, biodegrade more quickly than petroleum-derived plastics when exposed to soil or marine environments . In soil, CO₂-based polymers are broken down by microbial action, leading to fewer long-lasting pollutants. Additionally, these materials are less likely to fragment into microplastics, which are a major concern for both environmental and human health.
