biodegradable materials were generally In 2006, the Shanghai Biological Material Co., Ltd. with Jie Liang will be opened in Shanghai in the production of "corn plastic", is expected to more than 1,000 tons annual output will be. Currently the company's patent-pending plastic raw material - polylactic acid (PLA) project. The original direct polycondensation from lactic acid monomer molecular weight polylactic acid (PLA) of advanced polymerization process ("step" preparation). Advantage of the technology and outstanding performance in the production process: to obtain the high purity of the product, no precipitation; product conversion rate (higher than 20% of Rhizopus Act); energy consumption is low; the production of low cost, ex-factory price of about about ten thousand yuan a ton, close to the price of chemical plastic particles. comforter setsPolylactic acid with the United States, "two-step" preparation, production costs remain high, the price per ton in 3000 dollars. December 2005, the Shenzhen Municipal Science and Technology Co., Ltd. has successfully completed Aubert completely biodegradable material PHAs (polyhydroxyalkanoates) industry in the trial, and has reached with several international companies supply intentions. bed in a bagAll the raw materials of new products from crops and plants to complete its life cycle at 100% after the return to nature. In 2006, the Aubert built the first domestic investment, the world's second annual output of more than 5,000 tons of completely biodegradable material production line is expected to be built in Shenzhen. It is reported that Aubert's long-term goal, the first is to use genetic engineering technology to the biosynthesis of polyhydroxyalkanoates required pha, phb, and phc built on a variety of enzymes such as plants, the use of plants directly from the support functions in the body bed setsSynthesis of PHAs, to further reduce production costs. Second is the use of domestic agricultural advantages in the domestic built 10-20 5-10 ton annual output of the industrial base. In addition, the Institute of Chemistry of the (Beijing), Fudan University, Zhejiang University and other units have carried out polymerization of lactic acid. The Anhui Fengyuan Group, Changchun Corn Industry Zone, Chengdu Institute of Organic Chemistry Co., Ltd., Jiangsu Jiuding Group, Henan floating Security Group, Harbin Power Company and other companies have Dayao Ye construction or planned in the production line. bed in a bag setsCompletely biodegradable technology to achieve large-scale industrialization, fully biodegradable materials were generally used, the trust will give the Chinese plastics industry, a huge impact on energy resources, the economy will also contribute to sustainable development and environmental protection. The application of biomass plastics and prospects of biomass plastics by biological agricultural products made of starch, it has a wear-resistant, breathable, etc., can fully replace the chemicals and plastics, is regarded as following the metal materials, inorganic materials, polymer materials after " designer comforters | | 9:38a |
Academy has a pharmaceutical In other words, biomass plastics can not only overcome the traditional plastic manufacturing process problems caused by carbon dioxide emissions, and can get rid of abandoned after the "white pollution" of shortcomings. Some industry estimates, if there are 100 annual output of 10 tons of "corn plastic" of the manufacturers, the Chinese will end up leaving the "white pollution." Brought about by the development of biomass plastic is a more substantial economic benefits. 2004-2005 China Corn beginning stocks are estimated at 44.852 million tons, in the past 80% of these stocks for feed corn, "corn plastic" application, it will greatly enhance the added value of corn, increasing farmers income. comforter setsMr Chan said, raw material of plastic if developed, could bring a new industry group: front end of agriculture in the middle of fermentation and other biological transformation of the existing back-end is the largest chemical industry. During the large amounts of microbial fermentation occurs mainly in the business, will also drive a large number of plastic and textile industries upstream and downstream industries, and form the output value of at least 10 times more. 1 million tons to calculate the price, 100 million tons of plastic raw material output is 100 million yuan, the downstream products to produce 1,000 billion of output value, and this can save 500 million tons of crude oil. bed in a bagBiomass R & D and production of plastic raw material of plastic due to see, in particular the benefits of polylactic acid and market prospects, many domestic enterprises began to invest a lot of manpower and funds for the new product development and production. Changchun Institute of Applied Chemistry, Chinese Academy of Sciences built the largest poly L-lactic acid in the pilot production line. To achieve higher value use of corn starch, a "corn - starch - acid - PLA," the industry chain, bed setsChangchun should be achieved by the molecular weight of more than 10 million poly L-lactic acid in the large-scale preparation and biological materials in Zhejiang Hisun Limited completed 30 tons / year pilot production line. Currently the company is expansion, led to an annual output of 5,000 tons of the scale of polylactic acid resin. The company also set up a plastic Institute, has developed more than a dozen products, first exported to Japan. December 2005 by the Institute of Bioengineering, Chongqing University commitment to the national "863 Program" - fully biodegradable polymer materials development projects green inspection by experts. bed in a bag setsThe Academy has a pharmaceutical company in Chongqing City, formed a new biotechnology Co., Ltd., by promoting the industrialization process of polylactic acid. Currently, the company has successfully developed an annual output of 100 tons of continuous automated production equipment of polylactic acid, and plans to build 5,000 tons in 2006, the polylactic acid production line, production capacity within five years to the annual output of 20 tons. designer comforters |
