Paragraph starter
The review by Clark and Shaver (2024) highlights chemical depolymerization as a critical technology for achieving a circular economy in plastics. This process allows for the breakdown of complex plastic waste into its original monomers, enabling the production of virgin-quality recycled polymers. This is particularly important for waste streams that are poorly handled by traditional mechanical recycling methods, offering a pathway to reduce reliance on fossil fuels and minimize environmental pollution.
