HC Plastics News: Polymer chemists at Colorado State University have taken another step toward high-performance, renewable, biodegradable plastics.
The research team led by chemistry professor Eugene Chen published their findings in the journal Nature Communications, which describes the chemical synthesis of poly-3-hydroxybutyrate (P3HB). This compound can be used as an early substitute for petroleum bioplastic products used in industry.
Poly-3-hydroxybutyrate (P3HB) is a biological material commonly produced by bacteria, algae and other microorganisms and is mainly used in some biomedical applications. However, due to its high production cost and limited volume, the material is not suitable for a wider range of commercial applications.
The first author and researcher Xiaoyan Tang and his research team mainly used succinate (a lipid formed from succinic acid) as a raw material. The acid is produced by glucose fermentation, and the US Department of Energy first lists the optimal alignment of the 12 biomass-derived compounds to better replace petroleum-derived chemicals.
The researchers used a new chemical synthesis route to produce poly-3-hydroxybutyrate (P3HB), which is similar in performance to bacterial poly-3-hydroxybutyrate (P3HB), but its production route is faster and Commercial plastic applications offer greater, more cost-effective production potential. This new production route is achieved through a new class of potent catalysts they have designed and synthesized. They applied for a provisional patent for this new technology through CSU Ventures.
