May 20, 2025 – Southwest China has recently witnessed a landmark environmental initiative with the steady progress of the Chengdu Green Recycling Resources Smart Industrial Park, a food-grade rPET circular economy demonstration base developed by Chengdu Environment Investment Urban Services Co., Ltd., a subsidiary of Chengdu Environment Group. The main structure of the park’s comprehensive building has been successfully completed, while the construction of Plant One has reached 80%, signaling the project’s transition into a new phase of development.
The core business of the industrial park revolves around the efficient recycling and reuse of waste materials, with a particular focus on high-value processing of waste metals and plastics, primarily PET. According to Color Masterbatch Industry Network, the park is designed with an annual processing capacity of 50,000 tons of waste PET bottles, equivalent to transforming 2.5 billion discarded plastic bottles into valuable new resources. To achieve this goal, the park has incorporated internationally advanced intelligent sorting systems and integrated production equipment, ensuring precise classification, efficient conversion, and environmental friendliness throughout the entire process.
Upon arrival at the plant, plastic bottles undergo meticulous classification based on material and color. Specifically, transparent PET plastic bottles are selected and subjected to rigorous processes such as washing and shredding, transforming them into high-quality recycled PET flakes. These recycled flakes, with an annual output of approximately 40,000 tons, find applications across a wide range of industries, including textiles, bottle manufacturing, and industrial fibers, truly realizing “bottle-to-bottle” primary recycling.
Notably, the rPET produced through the park’s physical recycling process fully complies with stringent international food-grade regulations, including those set by the FDA and EFSA. This innovative approach not only reduces annual carbon dioxide emissions by up to 195,000 tons, equivalent to saving approximately 300,000 tons of oil, but also generates significant carbon sink benefits, contributing to the achievement of China’s “dual carbon” goals. Additionally, the project’s implementation has created numerous local employment opportunities, achieving a harmonious integration of ecological, economic, and social benefits.
