HNJD Lactic Acid Technology Group is a leading company in the field of lactic acid in China. It has a production capacity of 128,000 tons, accounting for 42% of the national production capacity. It is also one of the only three lactic acid producers in the world with a production capacity of more than 100,000 tons. Corbion-Purac, NatureWorks]. Lactic acid is widely used in the fields of food, polylactic acid, feed acidifier, daily chemical and medicine, and is in high demand.
The company uses microbial fermentation to produce lactic acid, masters a complete set of technologies from strain screening, fermentation process to separation and purification, and mainly produces high-purity L-type lactic acid.
Lactide is a Lactide (PLA monomer) for the production of polylactic acid (PLA) and has extremely high technical barriers. At present, only a few companies in the world such as Corbion-Purac of the Netherlands, NatureWorks of the United States, HNJD and ZJHZ Biomaterials Technology Group have mastered the production technology of lactide.
HNJD and Nanjing University jointly developed a process for producing lactide using biological organic guanidine catalysts. Organic guanidine catalysts can reduce the racemization rate at high temperatures and avoid the problem of metal residues caused by existing technologies. The company has already opened up lactic acid-lactide —The entire industrial chain of polylactic acid has the advantage of integration.
The company is the largest lactic acid manufacturer in China with the largest production capacity. Through cooperation with Nanjing University, the company will develop lactide technology. After technological breakthroughs, it will form a lactic acid-lactide-polylactic acid industrial chain layout. The promotion of the "plastic ban" is expected to accelerate the progress of the replacement of degradable plastics with traditional plastics, and stimulate demand for PLA and lactic acid.
