The shift towards CO₂-based polymers also brings significant advantages in resource efficiency. Conventional petroleum-based plastics rely on fossil fuels as a raw material, contributing to resource depletion and environmental degradation due to extraction processes. In contrast, CO₂-based polymers reduce this reliance by using a renewable and abundant feedstock: atmospheric CO₂. This shift promotes the circular economy concept, in which carbon is continuously recycled through various processes, from CO₂ capture to polymer synthesis and eventual degradation.
