The new network news starch and earth can also produce solid "plastic", buried in the soil can be completely degraded into water, carbon dioxide and nitrogen. A new technology from China would solve the "white pollution" hope.

In his hand and looked with Weifang, Shandong Weifang New Materials Co., Ltd. "bentonite modified starch environmentally friendly composite material" made of plastic lunch boxes, spoons, chopsticks, shopping bags, agricultural films, regardless of shape, color, hardness, toughness, and later to the same supermarket plastic products indistinguishable, but their predecessor is maize, cassava and other common starch.

"You can eat it!" Hua Wei, general manager of the New Materials Co., Ltd. Wang Song won a white granular he said. The white particles are added bentonite starch composite.

Last month, this new technology has been adopted EU standards on plastic packaging materials heavy metals, carbon content and qualified the degradation portion. 24, the China Packaging Association vice president Wang Lixuan cloth, the technology by expert appraisal that it is in the international advanced level.

Director Identification Committee, Vice-Chancellor Professor Liu Ye Qingdao University of Science, said the significance of this new technology is not only to promote the starch industry upgrade, plastics reduce production costs, the most important thing is to solve the white pollution, garbage flying status quo.

Plastic products in the traditional sense, based on oil quality as a basic composition to degradation in soil. 80 years ago polyethylene plastic invention, under ideal conditions theoretically, also takes 150 years to 200 years to be digested sunlight, water and other natural forces.

Liu Ye said, starch and bentonite from photosynthesis and the earth itself, and then use the deformation of dust, which allows people to maximize the enjoyment of science and technology and environmental win-win benefits.
