The project is located south of Xiangshan Road, north of Yandangshan Road, and west of Zhangjiagang Avenue in the Suqian High-Tech Industrial Development Zone. It involves Jiangsu Jinghong New Materials Technology Co., Ltd.’s project to produce 55,000 tons of polylactic acid per year, along with the manufacturing of the equipment needed for this production. The investment amount for this project is 600 million yuan. The latest update: On May 26, 2023, the People’s Government of Suyu District, Suqian City, Jiangsu Province, published a notice regarding the environmental impact assessment documents for Jiangsu Jinghong New Materials Technology Co., Ltd.’s project to produce 55,000 tons of polylactic acid per year.
This project uses the lactide ring-opening polymerization method to synthesize polylactic acid. Using lactic acid as a raw material, dehydration between lactic acid molecules is achieved through reduced pressure and heating; under the action of an initiator or catalyst, the PLA intermediate (lactide) is formed. This PLA intermediate is then purified and extracted, followed by polymerization to yield polylactic acid (PLA). The core technology of the project originates from an organostannic salt complex catalyst, as well as the invention patents and PCT applications related to the method for producing L-lactide. In 2018, the company began research and development on biodegradable materials, including PBAT, lactide, polylactic acid, and starch-based composites.
