A plastic circular economy aims to end plastic pollution by creating closed-loop systems where plastics are designed to be reused, recycled, or composted model. Today, through advanced technologies such like plastic-eating enzymes and chemical recycling waste plastics are efficiently transformed into high-value recycled materials and reproduce as household products widely used in daily life. By integrating eco-product design, AI-powered plastics sorting, high-end mechanical recycling and the development of biodegradable and plant-based plastics as alternatives, the plastic circular economy continues to promote industrial chain collaboration and systemic optimization.
