Changhong Bio has added an additional 180,000 tons of PBAT production capacity, with each production line having a capacity of 90,000 tons. Recently, the investment project for building a facility capable of producing 180,000 tons of PBAT per year at Zhejiang Changhong Biomaterials Co., Ltd. was approved by the Energy Conservation Review Office of the Shaoxing Development and Reform Commission. This project will add 2 new continuous polymerization lines for PBAT biodegradable plastics, with a designed production capacity of 90,000 tons per line. The total investment amount is 980 million yuan, and completion is scheduled for August 2024. By utilizing existing auxiliary and supporting facilities such as the condensate water system, wastewater system, and gas-fired organic heat carrier boilers, the facility will, upon completion, have an annual production capacity of 180,000 tons of PBAT biodegradable plastic, along with 19,800 tons of THF (**furan**) as a by-product. The main energy-saving measures for the project include the use of BDO steam injection to generate vacuum; the BDO in the plant is designed for complete recycling; process optimization of the esterification and polycondensation reactors, with the addition of an additional polycondensation system, which helps to reduce the material ratios, shorten the residence time, and lower heat consumption. Zhejiang Changhong Biomedical Materials Co., Ltd. mainly produces raw materials, modified materials, and finished products made from PBAT/PBT/PBS. In line with the broader trend of achieving carbon neutrality and addressing the issue of white pollution, Changhong Bio has decided to invest in the construction of a production facility for fully biodegradable thermoplastic plastics, with a capacity of 600,000 tons per year. This facility will be used to produce PBAT/PBS/PBT materials. The total planned production capacity is 600,000 tons of PBAT, and the project will be carried out in two phases, with each phase having a capacity of 300,000 tons per year; the overall construction period will be 5 years. In the first phase, a production line with an annual capacity of 120,000 tons was built for the first time, requiring an investment of 1 billion yuan; it has now been completed and put into operation. In addition, it is planned to invest in the construction of a natural gas deep-processing project in Qingyang, Gansu, to produce BDO; meanwhile, an investment will be made in a calcium carbonate-based degradation masterbatch project in Hezhou, Guangxi. This will enable the creation of an integrated industrial framework that covers the entire value chain of biodegradable plastics, spanning from BDO to PBAT and PBT products ； The industrial chain from PBAT and PBT modification to biodegradable products.
