Overseas research and development of biodegradable plastics
With thermoplastic molding processability. Chemical units into law most of the chemical units into the polymer material will not be microbial degradation. However, aliphatic polyester and water-soluble polymer, there is microbial degradation of the material easily. Chemical units into law is to biodegradable polymer material into the methods of chemical units. This method of production of plastic in the water-resistance strength, processing, molding, thermoplastic and so close to the existing plastics, biodegradable well performance. This is a natural substance usage stripping cellulose, starch and other natural polymer materials as the base material of the production method if the direct use of natural polymer material. Its strength, water resistance and other problems can arise. So. Most of the chemical denaturation and then want to use. Because the use of a natural material, nan the good biodegradability. And the use of starch and other materials, raw material prices are low, the corresponding product prices are lower 28996voI. sNo. 2cH1NAPACKAGING plastic made from the above method. The different physical properties, there are differences in their degradation are not entirely independent of each other, but also the starch and other natural polymer material, and other biodegradable polymer material mixed production. Several of the biodegradable material mixed production. In the physical properties,[link widoczny dla zalogowanych], degradation of performance,[link widoczny dla zalogowanych], price and other terms of units of mutual complementarity in the use of micro-organisms into the plastic, the micro-organisms use glucose and other substances in the fermentation of sugar Lou to produce polyester; chemical units into when organic acids such as lactic acid and succinic acid as raw materials However, these organic acids can also be used by microbial fermentation of sugar and starch in the system; natural products derived from the process, on the polymer chemical modification of biological resources, it has a thermoplastic, water-resistant features, such as plastic. Manufacturing principles are all biological resources will be recycled as raw materials and take advantage of Taiwan into Japan in the microbial, chemical synthesis and the use of natural materials and other aspects, is committed to use all raw materials and product development especially in the 90's. Technology development projects at national level was reported to carry out active and is currently in the sample stage. Has been part of the high-priced goods on the market in Japan in the practical study of biodegradable plastics Biodegradable plastics Committee will be practical for the future j ~ 10 years should be encouraged to go to the topic, they believe that a new era is coming plastic . More than half of Europe's waste disposal is used to Tian Hu (sea) made to reduce the plastic waste has become an important issue. Many European and American countries require producers to recycle packaging material obligation, along with the promotion of recycling. Awareness of the importance of using biodegradable plastics. Also in December 1994 + real banner of United States universities and national research institutions as the center, resulting in the accumulation of microbial research and development Xu, but also their chemical units into biodegradable plastics research. in the Midwest,[link widoczny dla zalogowanych], people want to use corn as an agricultural surplus industrial raw materials, 3,000 tons In 1994, a pilot plant start trial production 'ucc Chemical Company is producing biodegradable poly plastic spiritus class A In addition, another company in the production of ravioli Taiwan starch biodegradable plastics. British company ICI 7O's research and development since the mid-biodegradable plastics. to the late 70s. to develop Taiwan into a product of microbial later, with lower costs and the development of the shampoo bottles, food packaging and other plastic products with more than Italy The company has developed a mixed platform starch biodegradable plastics, the production of the garden products and bead pens used for treatment of waste fertilizer bags. Australia and Finland are to develop the present,[link widoczny dla zalogowanych], bio-degradable plastic prices higher. less The price is always the price of resin used 4 to 8 times. per kg price of biodegradable plastics will be the highest microbial synthesis products,[link widoczny dla zalogowanych], chemical products, followed by Taiwan, as the relatively low natural derivative products. In Plastics scale of production and equipment investment relationship. According to the types of plastics, production of raw materials differ. If the existing biodegradable plastics and plastic products to expand the production scale, like, you can reduce production costs. raw material prices also increases with the use of reduced. reduce the cost of biodegradable plastics, there must be a market to be guaranteed. biodegradable plastics suitable for modern Elsie's request, can replace a wide range of plastic products, according to estimates. The potential market in Japan, nearly 300 million tons. in biodegradable plastics and other plastic coexist at the same time, expanding the production scale of biodegradable plastics, reduce the cost required to reach the market size is possible.
