Abstract
Plastic waste management, particularly addressing the challenges of Polyethylene terephthalate (PET) waste, has become increasingly urgent in the face of escalating environmental concerns. This paper critically examines glycolysis-based PET recycling, focusing on its potential as a promising solution. Despite its lightweight properties and cost-effectiveness advantages, PET waste poses multifaceted challenges, including contaminant removal, scale-up hurdles, and economic viability. Catalyst optimization and maintaining end-product quality are crucial for enhancing recycling efficiency and market acceptance. Moreover, this review underscores the importance of environmental impact assessments and regulatory compliance in guiding sustainable waste management practices. To overcome infrastructure limitations and foster global collaboration, concerted efforts are needed to educate consumers and facilitate international cooperation. By addressing these challenges, glycolysis-based PET recycling holds promise in mitigating plastic pollution and promoting a circular economy. The paper highlights recent advancements in glycolysis-based PET recycling and examines potential applications for the resultant product, Bis HydroxyEthl Terephthalate (BHET).
