Plastic depolymerization is a chemical recycling technique that breaks down polymers into monomers or other valuable intermediates, enabling the regeneration of virgin-quality plastics. Technologies like enzymatic, catalytic, microwave-assisted, and solvent-based depolymerization target various polymers including PET, PU, PS, and polyesters. These processes allow for closed-loop recycling, reduced landfill dependency, and recovery of high-purity raw materials. Applications include packaging, textiles, automotive components, and electronics. Despite current energy and cost barriers, ongoing research and scaling initiatives position depolymerization as a key solution to plastic waste and circular economy goals .
