Chemical Recycling Techniques for PET-Based Waste: Challenges, Mechanisms, and Perspectives.DE

This study explores the chemical recycling techniques of PET-based plastic waste, focusing on methods such as hydrolysis, glycolysis, methanolysis, aminolysis, and enzymatic catalysis. These processes break down PET polymers into their original monomers, enabling the production of high-quality recycled materials. The study highlights the environmental benefits of chemical recycling, including the treatment of contaminated and colored plastics, and emphasizes the potential of innovative approaches like enzymatic and photocatalytic depolymerization. Overall, chemical recycling presents a promising solution for reducing plastic pollution and promoting sustainable resource management.
