On March 10, 2026, the annual production capacity of 15,000 tons of bio-based PDO for Shanxi Changqing Biotechnology Co., Ltd. was approved for registration. Project Name: Project for Annual Production of 15,000 Tons of Bio-based PDO
Project Code: 2603-140455-89-01-408874
Type of Approval: Filing
Nature of Construction: Renovation
Total Investment: 202,862,400 RMB
Project Start Date: September 2026
Project End Date: March 2028
Construction Location: South entrance of Gangshang Village, Yuzhe Town, Tunliu District, Changzhi City
Approval Status: Pre-review approved
Scale and Scope of Construction:
Scale of construction: Project for annual production of 15,000 tons of bio-based PDO;
Scope of construction: Utilizing existing equipment such as those for lysine production, saccharification, fermentation, extraction, and utility systems, a new distillation workshop, a decolorization workshop, a combined building, Class B warehouses, a fire pump room, and tank areas will be constructed, along with additional equipment such as distillation tanks and nitrogen generation stations. The project covers an area of 12,869㎡, with a building area of 22,615.6㎡. PDO is a colorless substance that is soluble in water and ethanol; it can be used as a humectant and preservative aid in various cosmetics and skincare products, as a taste modifier in beverages, and as an intermediate in drug synthesis. Its main use is as a polymer monomer for the synthesis of polytrimethylene terephthalate (PTT) fibers. The production of PDO can be carried out through chemical or biological methods. The chemical method has not seen further development due to its high investment costs, technical complexity, and elevated production expenses. In contrast, the biological fermentation method has become a focus of current research thanks to its advantages such as mild reaction conditions, simple operation, few by-products, good selectivity, low energy consumption, reduced equipment investment, and environmental friendliness. In June 2022, the production facility capable of manufacturing 20,000 tons per year of 1,3-propanediol produced by the sugar method (referred to as “PDO”), developed jointly by Changqing Biology and Guangdong Qingda ZhiXing Biotechnology Co., Ltd., was successfully put into operation for the first time, breaking the long-standing technical monopoly held by foreign companies. The PDO project is a key research project under the \"863\" program. Once Phase 1 of the project is put into operation, it will enable an annual production of 20,000 tons of PDO products, generating an additional output value of 600 million yuan. Upon completion of Phase 2, the annual production is expected to reach 200,000 tons of PDO products, with an output value of 6 billion yuan. This will provide a stable supply of PDO for industries in China such as polyester, polyurethane, cosmetics, and biodegradable plastics.
