On May 20, 2025, Yangzhou Huitong Biological New Materials Co., Ltd.'s annual production of 35000 tons of polylactic acid project (Phase I) was commissioned, and the first batch of qualified products were successfully produced. Previously, the pilot phase of the project was completed in 2023 and has now entered the 10000 ton commissioning phase.

This project uses the independently developed propylene ester production process and key equipment of Yangzhou Huitong Technology Co., Ltd., and adopts Sulzer's propylene ester purification and polymerization key equipment and technology. The products produced can be used in the fields of fibers, plastics, 3D printing, and films, and can meet the diversified needs of the market.
 

Polylactic acid, as a fully biodegradable material based on plant resources, has both biodegradability and food grade safety characteristics. It can effectively replace traditional petroleum based materials, reduce carbon emissions, and play a positive role in achieving the "dual carbon" goal.

Huitong Biotechnology will use this trial production as a starting point to accelerate core technology research and product iteration, expand product applications in high value-added fields such as textiles and healthcare, and further solidify its industry position, contributing more to global green and low-carbon development.
