Henan Huiyang, 1000-ton high molecular weight polylactic acid pilot project begins construction.

On March 28, 2025, Henan Huiyang Biotech New Materials Co., Ltd. constructed a pilot demonstration line for the production of 1,000 tons of high molecular weight polylactic acid per year.

The total investment for this project is 61 million yuan, with the construction of one production workshop, one warehouse, and one office building. Main equipment includes: distillation tower, hydrolysis tank, crystallizer, reactor, stripping kettle, underwater granulator, electric thermal oil furnace, and various pumps.

The main research focuses on the process route of synthesizing polylactic acid through the ring-opening polymerization of lactide, conducting experiments on the influence of reaction temperature, reaction time, and catalyst dosage on the molecular weight of polylactic acid. Through these experiments, the process conditions for polylactic acid are optimized, laying a foundation for the large-scale production of polylactic acid with high molecular weight and high crystallinity in the future.

Previously reported, on January 7, 2025, the开工暨揭牌仪式for the high molecular weight polylactic acid project of Henan Huiyang Biopolymer New Materials Co., Ltd. was held in the Moshan Park area of Shancheng District. Zhang Donghong, vice president of Henan Investment Group, attended and delivered a speech; Hu Hongjun, vice mayor of Hebi City, announced the start of the project. At the ceremony, Zhang Donghong and Hu Hongjun jointly unveiled Henan Huiyang Biopolymer New Materials Co., Ltd.

The establishment of Henan Huiyang Biological New Materials Co., Ltd. is the result of cooperation between Shancheng District, Henan Investment Group, as well as HighChem Co., Ltd. and Hebi Investment Group. The commencement of the high molecular weight polylactic acid project is of great significance for Shancheng District to promote the high-quality development of the synthetic biology industry.

The high molecular weight polylactic acid project has a total investment of 500 million yuan. Phase one will construct a thousand-ton production line to seize the high-end market in advance; phase two plans to build a ten-thousand-ton production line, thus smoothing the upstream industrial chain. The products will be widely used in medical materials, beauty microspheres, nanofibers, and other fields. After completion, the annual operating revenue can reach 800 million yuan, which will strongly promote the development of the bio-based new material industry cluster, making greater contributions to Jihyang City's construction as a demonstration city for high-quality development in the new era.

Henan Huiyang is a holding subsidiary of Henan Biological Industry Group Co., Ltd. Under Henan Biological Industry Group, there are also subsidiaries such as Xintuo Yang Biological Engineering Co., Ltd., Henan Qiye Technology Development Co., Ltd., Zhengzhou Tuoyang Industrial Co., Ltd., and Zhengzhou Tuoyang Biological Engineering Co., Ltd. In September 2024, Henan Qiye completed the construction of the world's first thousand-ton non-grain crystalline glucose production line and continued to expand its production scale, with a ten-thousand-ton demonstration line expected to be completed by the end of 2024.
