HC Plastics News: On October 21st, at the 2018 International Bio-Polyester Conference (ISBP), Chen Guoqiang, a professor at the School of Life Sciences at Tsinghua University, said that the chemical nature of plastic waste determines that it will cause serious pollution. The landfill of plastic waste occupies a large area of ​​land and cannot be degraded for hundreds of years. Chen Guoqiang said that since plastic is a high molecular polymer formed by polymerization of monomers, microorganisms in the environment cannot digest the chemical bonds that link the monomers in the plastic. Therefore, the plastic cannot be re-decomposed into a monomer form. "In other words, once plastic is synthesized, there is no turning back." Chen Guoqiang said. Therefore, if plastic garbage is eaten by wild animals, it will cause animal injury or death; when it is burned, it will produce a lot of toxic gases... It is worth mentioning that plastic waste is the most serious pollution to the sea. Science magazine reports that 8 million tons of plastics eventually enter the ocean each year. What is even more frightening is that through the consumption of seafood and other means, a large number of plastic particles will enter the human body, and plastic poses a great threat to people's health. These are all problems caused by the inability to degrade plastics. Therefore, scientists all over the world are trying to make a substance that has excellent polymer properties like plastic, can be easily degraded and is non-toxic and harmless. "Bioester" offers this possibility. It is understood that common bio-polyester materials are polyhydroxyalkanoate (PHA), polylactic acid (PLA) and polybutylene adipate/butylene terephthalate (PBAT). PHA materials can be degraded under natural conditions and are harmless to humans and the environment. Due to the variety of monomers, polymerization methods and polymer chain lengths are very different, materials with different material properties, such as common packaging materials and agricultural films, can be produced. In addition, PHA's market prospects in pharmaceuticals, cosmetics, animal feed, etc. are also very broad. In recent years, the basic research and industrialization of new bio-polyester materials represented by PHA has progressed rapidly. “The biggest obstacle to further industrialization and scale of bio-polyester materials is cost. If the cost of technology is reduced, everyone is very willing to use this material. We are also constantly looking for ways to reduce costs to promote PHA.†Chen Guoqiang told Journal of the Chinese Journal of Science. In December last year, Chen Guoqiang’s “Next Generation Industrial Biotechnology†completed the pilot test of PHA industrial production, and realized the low-cost PHA mass production capacity without sterilization and open continuous fermentation. It can be seen that in the future, bio-polyester materials may replace traditional plastics and enter thousands of households. It is reported that the International Bio-Polyester Conference (ISBP) is held every two years. This conference (ISBP2018) is hosted by Tsinghua University, Chen Guoqiang is the chairman of the conference, and experts from the Royal Swedish Academy of Engineering, Ann-Christine Albertsson, surround the biodegradable bio-polyester material. An academic discussion was launched to help bio-polyester materials go into industrial production.
