Corn soybeans made of environmentally friendly plastic

Yesterday morning, the Provincial Department of Science and Technology held a scientific and technological achievements conference in Zhaoqing City. A new type of fully biodegradable plastic technology passed the appraisal of experts from Guangdong Province, and has already filed four national invention patents and was listed in the “2005 National Torch Plan”. "And the "provincial major science and technology projects" project. The "white pollution" problem that has plagued the world for many years is expected to be completely resolved.

The plastic is completely biodegradable


This technology can completely replace the non-renewable petroleum by-product polystyrene raw material. Its upstream raw materials are mainly starch made from corn, soybeans, potatoes, cassava, balloonflower, and appropriate amounts of polyvinyl alcohol, glycerin, and core additives, etc. The "completely biodegradable plastic" pellets are produced directly from the pellets and the plastic products are directly produced. The production process is basically based on the original processing equipment of the plastics company, and will not impact the original production structure.

National Plastic Products Quality Supervision and Inspection Center, National Engineering Research Center for Novel Polymer Molding Equipment, South China University of Technology Polymer Testing Engineering Ministry of Education Key Laboratory Analysis and Testing Center issued a product test report showing that the 28-day biodegradation rate of the new plastic, Vertical and horizontal strength, elongation at break, and angle tear strength have reached world advanced levels. The production cost of pellets is only 9,000~9500 yuan/ton, which is 90% of the polystyrene price, about 20% of foreign similar products, slightly lower than the price of ordinary plastics currently used, it can replace the production of packaging film, agricultural film, Plastic film, disposable tableware, daily-use plastics, foam filling materials for packaging, anti-counterfeit packaging, electrical enclosures, forestry garden seedlings, etc. At present, the product has completed laboratory debugging and product testing, and completed industrial production debugging at South China University of Technology.

At present, companies in 13 provinces and cities, including Jiangsu, Chongqing, Beijing, Shanxi, and Henan, have reached cooperation intentions. According to preliminary estimates, according to an average of 1.5 million tons per province, city, or municipality, the country will create a production value of 800 billion yuan, a national revenue tax of 100 billion yuan.

According to reports, the relevant government departments attach great importance to this technology and ranked first among the 15 projects in the “2005 National Torch Program” in Guangdong Province. This technology is independently researched by Chinese science and technology personnel and has completely independent intellectual property rights. Technology is at least 5 to 10 years ahead of similar international products.

Experts believe that the overall technology of this completely degraded environmental protection product is at the leading level at home and abroad and is expected to completely solve the "white pollution" as a worldwide environmental problem.
