  When traditional plastic products gradually evolved into a “white pollution”, everyone constantly called for a green alternative to enter our lives. Pursuing this dream, an innovative team of Hisun Group, which has been rooted in the laboratory for more than ten years, has finally developed a biodegradable polylactic acid material and promoted the industrialization of this new biomaterial.
 
  From fast food boxes to regular water cups to fiber gloves, the daily necessities you see in front of you are made from this new type of biomaterial. When the starch-containing corn is processed into a colorless and transparent liquid lactic acid by modern biotechnology, a special polymerized reaction produces a granular polymer material polylactic acid. This polylactic acid is the innovation of Haizheng Group's test of biological materials. Leading this product development is the Haizheng Group's polylactic acid research and development and application technology innovation team.
 
  As a traditional raw material drug manufacturer, Haizheng Group started cooperation with the Changchun Institute of Applied Chemistry of the Chinese Academy of Sciences in 2000 and decided to carry out related industrialization research in the field of polylactic acid. At that time, only the only NatureWorks company in the United States that could realize the industrialization of polylactic acid. The decision of the Haizheng Group also made it possible for Bian Xinchao, who was always immersed in the experiment of polylactic acid materials in Changchun Institute of Applied Chemistry.
 
  Bian Xinchao, deputy general manager of Zhejiang Hisun Biomaterials Co., Ltd.: "For me personally, it is also a good opportunity. We can transfer the results of the laboratory into industrialization. This is what we do as researchers. A wish or a lifelong pursuit."
 
  After completing the pilot and pilot production, in 2007, the first demonstration production line of polylactic acid with an annual output of 5,000 tons was successfully produced in Haizheng. With the launch of this production line, it also marks that China has become the second country in the world to realize industrial production of polylactic acid. Since then, Hisun Group has been rushing to fight iron, expanding production capacity all the way, and now has formed 15,000 tons of polylactic acid production capacity.
 
  Bian Xinchao, deputy general manager of Zhejiang Hisun Biomaterials Co., Ltd.: "Our project has gone from the laboratory to a production capacity of 15,000 tons now. We are now sharing it for 15 years."
 
  In Bian Xinchao's view, the 15 years of history have not been smooth, and even full of risks and tests. Soon after the Haizheng polylactic acid project was officially put into the market, a crisis came along. The polylactic acid products exported by a downstream company had serious quality problems when they arrived at the customer's national dock across the sea. After investigation, it turned out that the temperature concentration in the highly sealed container during long-distance transportation increased, exceeding the heat-resistant point of polylactic acid by 60 degrees, thus causing thermal deformation of the product. How to improve this defect and improve the heat resistance of polylactic acid has naturally become a difficult problem for the Haizheng polylactic acid research and development team.
 
  Bian Xinchao, deputy general manager of Zhejiang Hisun Biomaterials Co., Ltd.: "We probably invested a lot of energy, manpower, and financial resources in this process for two years. But the good news is that we finally put it in this puzzle. Conquered, we can also be regarded as the first in the industry."
 
  Today, the heat-resistant point of Haizheng polylactic acid products has been increased from 60 degrees to 120 degrees, and this performance is even better than foreign products.
 
  It is worth mentioning that at the end of last year, Haizheng Group spent nearly 1 billion yuan to launch an annual production of 50,000 tons of polylactic acid industrial chain project in the circular economy industrial cluster in Taizhou Bay. Upon completion, it will become the largest polylactic acid production in Asia. base. As the most ecologically friendly material with potential application development, the promotion and application of polylactic acid will also lead to the transformation and upgrading of Taizhou biomedicine and traditional plastics industry.
