Haizheng polylactic acid project: "corn change plastic" to fill the domestic gap
When traditional plastic products gradually evolved into a "white pollution", people kept calling for a greener alternative to our lives. Chasing the dream, the sea is group of an innovative team, more than ten years like one day take root in the laboratory, and finally successfully developed a biodegradable characteristics of polylactic acid materials, and promote the industrialization of new biological materials to realize.
From the fast-food box to the regular water cup, to the fiber glove, the daily necessities you see are made of this new material. When the starchy corn is processed into colorless and transparent liquid lactic acid through modern biotechnology, the granular polymeric acid is produced by special polymerization. This polylactic acid is the result of the innovation of the sea - positive group. The research and development of this product is the r&d and application technology innovation team of haizheng group.
As a traditional API production enterprise, the sea is group as early as in 2000 started the cooperation with Chinese academy of sciences changchun institute of applied chemistry, decided to develop industrialization of related research in the field of polylactic acid. At that time, the only company in the world that could industrialize polylactic acid industrialization was NatureWorks of the United States. The decision by haizheng group, meanwhile, also made it possible for the research institute of applied chemistry in changchun to see the opportunity.
Zhejiang sea is biological material co., LTD., vice general manager of the new super: "for me personally, is also a good opportunity, we put the results of laboratory can transfer it into industrialization, this is what we are doing a wish in the scientific research personnel or the pursuit of life."
After the completion of the pilot and pilot production, in 2007, the first domestic production of 5,000 tons of polylactic acid demonstration production line was successfully made in the sea. With the production of this production line, it also marks our country as the second country in the world to realize the industrialization of polylactic acid. Since then, haizheng has been working hard to expand production capacity, and has now produced 15,000 tons of PLA production capacity.
Zhejiang sea is biological material co., LTD., vice general manager of the new super: "we this project from the laboratory to now a production capacity of 15000 tons, we share a now is 15 years."
The 15 years have not been smooth and even fraught with risks and tests. A crisis ensued shortly after the project was officially launched in the sea. The export of polylactic acid products from a downstream company has a serious quality problem when it reaches the customer's national wharf. After investigation, the temperature concentration in the container with high density in the distance of long-distance transportation was raised, which exceeded the heat resistance of polylactic acid 60 degrees, thus resulting in the heat deformation of the product. How to improve this defect and improve the heat resistance of polylactic acid has become a difficult problem for the research and development team of haizheng.
Zhejiang sea is biological material co., LTD., vice general manager of the new super: "the process we took about two years, has invested a lot of energy and manpower, and financial resources, but the good news is that eventually the problem we are to overcome it, we in the industry and also was a first."
Today, the hotspots for the sea's polylactic acid products have risen from 60 degrees to 120 degrees, a performance that is even better than foreign ones.
It is worth mentioning that the end of last year, the sea is group spent nearly 1 billion yuan in taizhou bay cyclic economic industry cluster area on the annual output of 50000 tons of industrial projects, poly (lactic acid) (PLA) is completed, it will become Asia's largest production base of poly (lactic acid) (PLA). The application of polylactic acid will also lead the transformation and upgrading of bio-medicine and traditional plastics industry in taizhou as the most promising ecological environment material.
