Latest News: In June 2022, Guangdong Qingda Zhixing Biotechnology Co., Ltd. (hereinafter referred to as "Qingda Zhixing") and Shanxi Changqing Biotechnology Co., Ltd. (hereinafter referred to as "Changqing Biotechnology") joined forces The built sugar 1,3-propanediol (referred to as "PDO") production unit with an annual output of 20,000 tons was successfully started.
This is Tsingtao Zhixing's successful application of a new generation of sugar-based 1,3-propanediol production technology to a 10,000-ton production line after the successful commercialization of glycerol fermentation production of 1,3-propanediol technology in 2018. Tsingtao Zhixing has become the only high-tech enterprise in the world that has mastered "glycerol + sugar multi-raw PDO fermentation technology" and realized industrialization.
The project is located in Changzhi City, Shanxi Province. After the first phase is put into operation, it will form a bio-based 1,3-propanediol production capacity of 20,000 tons per year, providing a stable source of PDO for polyester, polyurethane, cosmetics, degradable plastics and other industries.
After more than 20 years of technical research, the technical team with Professor Liu Dehua from Tsinghua University has mastered the large-scale production technology of glycerol PDO with completely independent intellectual property rights, and solved the key "stuck neck" problem in the development of the PTT industry chain. It has fundamentally broken through the restrictions on the development of polyester, polyurethane, cosmetics and pharmaceutical industries in my country due to the absolute monopoly of bio-based PDO preparation technology by foreign companies for more than 20 years.
Changqing Bio is a large-scale specialized corn deep-processing enterprise integrating R&D, production, sales, logistics and transportation, and biotechnology development. It has a complete governance structure, advanced production equipment, and first-class workshop management experience.
Qingda Zhixing and Changqing have complementary biological resources and have the same philosophy. In order to ensure the smooth progress of the sugar fermentation production 1,3-propanediol project with an annual output of 20,000 tons, on May 18, 2022, Shanxi Qingda Changxing Biotechnology Co., Ltd. was jointly established. Company (referred to as "Qingda Changxing").
Since the implementation of the project, Tsingtao Zhixing and Changqing Biotechnology team have gone all out to successfully complete the transformation and upgrading of the first domestic sugar-based 1,3-propanediol production unit in just 2 months. Using the starch sugar with favorable price and high quality from Changqing Biotechnology as raw material, and using the mature sugar fermentation technology of Qingda Zhixing to produce 1,3-propanediol, "pointing stone into gold". Qingda Changxing realized the commercialization of the first sugar-based bio-based 1,3-propanediol project in China to meet the major needs of my country's consumption upgrade in the fields of textiles, clothing, and polyurethane.
The sugar fermentation production 1,3-propanediol project with an annual output of 20,000 tons is the first project of Tsingda Zhixing and Changqing Bio. Start the construction of a PDO production base with an annual output of 100,000 tons, further expand the scale of PDO production, and accelerate the process of further large-scale internationalization of PDO production.
