Changchun from the Chinese Academy of Sciences to understand that the researcher Wang Junhong team will be carbon dioxide ' waste ' as Bao, lasted 20 years to achieve the carbon dioxide-based biodegradable plastic industrial production, an annual output of 50,000 tons.
Carbon dioxide is the main ' culprit ' of the greenhouse effect, but it is also a low-cost carbon resource, which can be used as raw material to synthesize carbon dioxide-based biodegradable plastics, the degradation products of the environment pollution-free, and low production costs. Since 1997, Changchun Institute of Chinese Academy of Sciences began to layout the application of carbon dioxide-based biodegradable materials research. ' The principle of synthetic carbon dioxide-based biodegradable materials is not difficult, the difficulty is how to develop high-activity catalysts to synthesize the polymer carbon dioxide-based plastics, and through the low-cost modification of this material to achieve the best properties.
' said Wang Junhong. Through the technical cooperation with many enterprises, after repeated testing, the team completed in 2014 the performance of high molecular weight carbon dioxide-based biodegradable plastics industrial process design.
The results obtained by the National Natural Fund of the Outstanding Young Science Fund and other support, access to the United States 2 pieces of patents, Japanese patents 1, the Chinese invention Patent 27, the formation of a sound independent intellectual property rights.
At present, the carbon dioxide-based biodegradable plastic has achieved production, industrial production capacity of 50,000 tons per annum, can be used for the preparation of plastic bags, express packaging and so on.
At the same time, the plastic film made from this material has been tested for 4 consecutive years by Chinese Academy of Agricultural Sciences and other scientific research institutions, which is expected to provide a new breakthrough for solving the residual pollution of the farmland film. Chinese scientists use carbon dioxide to synthesize new biodegradable plastics for mass production
