The production cost of polyhydroxyalkanoates is high and the production process needs to be improved as soon as possible.

Polyhydroxyalkanoate (PHA) is an intracellular polyester synthesized by bacteria and is a substance that stores carbon sources and energy in organisms.

Polyhydroxyalkanoate not only has physical and chemical properties similar to those of synthetic plastics, but also has excellent properties such as biodegradability, biocompatibility, optical activity, piezoelectricity, and gas barrier properties. It is an ideal substitute for synthetic plastics. Polyhydroxyalkanoate is a research hotspot in the field of biomaterials. It has broad application prospects in biodegradable packaging materials, tissue engineering materials, sustained-release materials, electrical materials and medical materials, and has huge market demand.

Polyhydroxyalkanoate is also used in the field of medical beauty. Regenerative material injections use polyhydroxyalkanoate microspheres as the main component. At present, my country’s recycled materials industry has become a new blue ocean. It is expected that the market penetration rate will continue to increase, and the market demand for polyhydroxyalkanoates will expand accordingly.

According to the “2023-2028 China Polyhydroxyalkanoate Industry Market In-depth Research and Development Prospects Forecast Report released by the Industrial Research Center It shows that the current production process of polyhydroxyalkanoates is mainly divided into biological synthesis and chemical synthesis. The chemical synthesis method is further divided into hydroxy acid direct condensation polymerization and lactone ring-opening polymerization. The biosynthesis of polyhydroxyalkanoates is mainly carried out in cells. This method produces polyhydroxyalkanoates with higher quality and purity, but it has high equipment requirements, long production cycle, low product output rate, high process costs and limitations. The application range of polyhydroxyalkanoate.

The method of chemically synthesizing polyhydroxyalkanoates has the advantages of low production cost, short cycle, and relatively simple process flow. It can control the product structure and improve product quality. However, the raw material hydroxy acid is unstable in nature and can easily shed molecules when exposed to high temperatures. Cause contamination to the product and affect product purity. my country’s polyhydroxyalkanoate companies still need to explore better production processes, reduce production costs while improving product quality, and promote the widespread application of polyhydroxyalkanoate.

As an environmentally friendly material, polyhydroxyalkanoate industry development is strongly supported by national policies. At the end of 2022, the country released the “Strategic Guidance Outline for Expanding Domestic Demand (2022-2035)” and in March 2023, it released the “Outline for Building a Quality Power”, both of which proposed to encourage enterprises to increase investment in technological innovation and promote the application of new technologies, new processes, and new materials. . These policies will promote the development of new products and improve production technology in the polyhydroxyalkanoate industry.

The development of polyhydroxyalkanoate production technology has attracted academic attention. Peking University, Tsinghua University, Chinese Academy of Sciences and other academic institutes have established polyhydroxyalkanoate-related scientific research projects. Industry analysts said that polyhydroxyalkanoate manufacturers can establish cooperative relationships with research institutes and use the latest academic research results to innovate Production technology to improve production efficiency.
