With the global emphasis on plastic recycling, countries and regions such as the EU, the United States, and Japan have successfully issued policies to increase the proportion of recycled plastics (rPET). For example, the EU speculates that the proportion of recycled materials in PET bottles must reach 25% by 2025 and increase to 30% by 2030. Against this background, Shangrao Bisource Technology Co., Ltd. Actively responded to the policy call and invested in the construction of a food-grade recycling and modification project with an annual output of 120,000 tons, focusing on the recycling, cleaning and modification of waste PET bottles to meet the demand for high-quality recycled plastics in the domestic and foreign markets.
