SHEIN and Donghua University Unveil Next-Generation Recycled Polyester Technology for Circular Fashion
Shanghai, China - January 24, 2025: Global fashion and lifestyle e-retailer SHEIN, in collaboration with Donghua University, announced the development of a cutting-edge polyester oligomer recycling solution that expands the scope of recyclable materials to include pre- and post-consumer polyester waste such as discarded textiles and PET bottles. This innovative technology combines the advantages of physical and chemical recycling methods, addressing the limitations of current industry practices.
Traditional physical recycling of polyester has limited application scope and results in downgraded materials, while chemical recycling, though enabling closed-loop recycling, is cost-prohibitive and complex to scale. The new solution developed by SHEIN and Donghua University overcomes these challenges by allowing repeated recycling of polyester without significant loss of material performance, as verified by tests conducted by Donghua University. This flexibility in raw material sourcing is expected to reduce costs and improve efficiency for manufacturers.
SHEIN plans to roll out the technology to its industrial suppliers by June 2025, with an initial annual production capacity of 3,000 tons of recycled fiber. The collaboration aims to establish a closed-loop recycling system covering both pre- and post-consumer polyester waste, supporting SHEIN's goal of replacing 31% of virgin fibers with recycled alternatives by 2030. This initiative aligns with global sustainability goals, including the UN Sustainable Development Goals (SDGs) and China's national targets to establish a comprehensive waste textile recycling system by 2030.
In addition to the new recycling technology, SHEIN has implemented various sustainable practices, such as the "SHEIN X Rescued" collection that repurposes excess fabric from the industry, partnerships with sustainable fashion enterprises like Aloqia, and participation in initiatives like CanopyStyle and Pack4Good. The company also established funds to support textile waste management and innovation in recycled materials.
