The press conference of "Next Generation Industrial Biotechnology" and the signing ceremony of Strategic Cooperation between Yancheng District Government and the Center for Biosynthesis and Systems Biology of Tsinghua University Life Science Academy were held today in Yanzhou District, Jining City, Shandong Province. PHA (Polyhydroxyalkanoate) Project uses sustainable agricultural products such as corn starch as raw materials to produce biodegradable PHA through microbial fermentation process PHA project adopts the next generation industrial biotechnology platform pioneered by Professor Chen Guoqiang of Tsinghua University and is a world leader Of the halophilic microbial technology, the production cost is only 50% of the existing technology, alternative to petroleum-based plastics to solve the white pollution problem.
The project is invested by Beijing Lanjing Microbial Technology Co., Ltd. and Parkson Biotechnology Co., Ltd., a subsidiary of Tsinghua University, and adopts the largest plastic bioreactor in the world with high technological content, low environmental cost and environmental protection, which leads the international industry. The project has a total investment of 1.2 billion yuan, a production capacity of 100,000 tons / year, a revenue of 2 billion yuan and a profit tax of 300 million yuan. At present, the project has a complete pilot production line of PHA, Bacteria open continuous fermentation of low-cost PHA production capacity, the transformation and upgrading of China's bio-manufacturing industry play a historic role in promoting.
The project has three major bright spots: First, to achieve high-efficiency open-end continuous fermentation without sterilization, reducing energy consumption and complex operation of sterilization, greatly reducing labor costs; the second is to cultivate halophilic microorganisms need high concentrations of salt substrate culture It can use high-salt wastewater to replace freshwater resources and greatly save water resources. Third, bioreactors use materials such as plastics or ceramics without the need of high-temperature and high-pressure stainless steel materials, which greatly reduces the production cost.
PHA products can be widely used in the field of high added value of artificial implants such as artificial bone nail, drug carrier, artificial blood vessel, cartilage, valve, film, suture, etc. The market of PHA products is promising. Membrane, one-time wood flour blended and pure PHA tableware, color 3D printing silk, electrospun fibers, shopping bags and other end products.
Previously, due to the high cost of producing PHA, the price was much higher than other biodegradable materials, so despite its excellent mechanical properties and 100% complete biodegradability, PHA accounted for only 5% of the market for biodegradable materials, well below PLA and PBAT. The new PHA production technology released this time can greatly reduce the cost of energy consumption, raw materials and equipment input in fermentation production. It is estimated that PHA costs will continue to drop in the next five years and substantially increase its market share.
