Recently, in Wuhan Gorgeous Environmental Protection Technology Co., Ltd., after Bai Juan was busy, in the morning to guide team members in the laboratory to conduct chemical analysis and testing, went to the workshop in the afternoon to check the operation of the biodegradable material production line and biodegradable film bag product production line. "My work is popular, which is to study how to use natural polymer materials such as plant starch to replace traditional petroleum -based plastics, create various packaging bags and disposable supplies, so as to achieve oil saving resources, reduce carbon dioxide emissions, and achieve harmless garbage harmless Treatment and eliminating the purpose of 'white pollution'. "

In July 2005, Bai Juan graduated from Zhengzhou University's master's degree in polymer materials and came to Wuhan Gorgeous Environmental Protection Technology Co., Ltd. to become an ordinary scientific researcher and set foot on the long journey of biodegradable plastic research. With a love, Bai Juan is 17 years old.

Following Bai Juan to the granular workshop, a reporter from the Yangtze River Daily witnessed the "magic transformation" of the starch. I saw a biodegradable material production line is operating efficiently. A bag of starch of white flowers entered the reactor from the portal port. The biological basis is fully degraded. Bai Juan told reporters that after years of research and development, they use natural polymer materials such as starch, straw powder, and grain shell as the main raw materials to chemically modify them, and then mix the modified starch with the synthetic biodegradable polyester and do it. Bio -based biological radicals can degrade plastic. This biological base degradable plastic can be made into a film bag product after plastic mixing, bleeding and traction, folding and printing rolls and printing.

The decomposable plastic bag looks no different from ordinary plastic bags, but the touch is very soft and thin. Bai Juan picked up a stack of degradable plastic bags with ordinary plastic bags for comparison: "Ordinary plastic bags are petroleum -based products, which affects the urban environment after being discarded, causing 'white pollution'; Or under specific conditions (such as compost), it can be completely degraded into carbon dioxide and water in half a year. "

In order for the product to stand the inspection, Bai Juan consulted a large amount of information and often developed regardless of day and night. She led the team members to encounter a collective research, and she started again when she failed. With a toughness and innovation spirit, more than 20 brand of bioplastics developed by Bai Juan's team is exported to the world and is widely used in food packaging, agriculture, express delivery and other industries.

From researchers to managers, Bai Juan grew up all the way and applied for a total of 23 domestic and foreign invention patents and 1 utility model patent. At present, there are 12 patents authorized, including 1 US invention patent and 1 Australian invention patent, 9 Chinese invention patents, and 1 utility model patent. At the same time, she is also the first grassman of the National Standard GB/T33796-2017 "The Technical Requirements for thermoplastic Starch Common for thermoplastics".

Speaking of the future, Bai Juan said: "I will further enhance the added value of environmental materials and the application field of the application of bioplastics. I hope to use advanced technology to let more consumers use environmentally friendly products. A citizen, starting from me, starting from small things, respecting nature, protecting the environment, using environmentally friendly products, and making green water and green mountains. "
