Issue 42/2015 - Bentonite modified starch materials are expected to crack white pollution

Solid "plastic" can also be made from starch and soil, which is buried in the soil and completely degrades into water, carbon dioxide and nitrogen
.
A new technology from China will bring hope
for a complete solution to "white pollution".

Plastic lunch boxes, spoons, chopsticks, shopping bags, and agricultural films made of "bentonite-modified starch environmental protection composite materials" of Shandong Weifang Huawei New Materials Co.
, Ltd.
, regardless of shape, color, hardness, toughness, are no different from similar plastic products purchased in supermarkets, but their predecessors are corn, cassava and other ordinary starches
.

Last month, this new technology passed the qualification certification
of heavy metals, carbon content and degradation parts of the EU plastic packaging material standard.
On October 24, Wang Li, vice president of the China Packaging Federation, announced that the technology had passed the expert group's appraisal and considered it to be at the international advanced level
.

Professor Liu Guangye, director of the appraisal committee and vice president of Qingdao University of Science and Technology, believes that the great significance of this new technology is not only to drive the upgrading of the starch industry and reduce the cost of plastic production, but also to solve the current situation
of white pollution and garbage flying all over the sky.

Plastic products in the traditional sense are based on petroleum as the basic composition, which is difficult to degrade
in the soil.
Polyethylene plastic products invented 80 years ago, under theoretical ideal conditions, also take 150~200 years to be digested
by natural forces such as sunlight and water.

Starch and bentonite themselves come from photosynthesis and the earth, and then return to dust after deformation and use, which allows people to enjoy the win-win benefits
of technology and the environment to the maximum.
