Against the background of the depletion of petroleum resources and the promotion of low-carbon environmental protection worldwide, bio-plastics have incomparable advantages over traditional plastics in terms of resource utilization and degradation. As the leading species in the family of bioplastics, polylactic acid (PLA) is favored by all parties for its good compatibility and degradability.
Polylactic acid, also known as polypropyl, is a new type of polyester material produced from lactic acid. Due to lactic acid is made from corn, cassava starch made by microbial fermentation, and then forms through chemical synthesis polylactic acid, thus the synthesis of poly (lactic acid is a kind of renewable resources of plastic materials.
According to low carbon production of biological materials innovation alliance director Yang yi xushuguan introduction, application is very extensive, of poly (lactic acid) (PLA) can be used for processing from the industrial to the civilian all kinds of plastic products, packaged food, fast food lunch box, non-woven fabrics, industrial and civilian cloth, can also be processed into agricultural fabric, health care, health supplies and tent fabric, such as cloth market prospects look good. Polylactic acid is also widely used in the field of medicine. It can be used for the production of disposable infusion equipment, non-removable surgical suture line, bone nail, etc.
Because polylactic acid can be completely degraded after use and will not cause environmental pollution, its technology development has become a hot topic of current research, which can be seen from the application of patent related to polylactic acid in recent years. Journalists from the state intellectual property office of the retrieval platform, according to data from polylactic acid related technology more and more get the attention of research institutes and enterprises, from 1997 to 2010, the total number of domestic patent applications poly (lactic acid) (PLA) is a growing trend, the largest number of 2008 reached, an application for a patent for poly (lactic acid) (PLA) count as the top of biodegradable plastics field, about 38% of the total of all kinds of biodegradable plastics applications. In addition, the application fields of polylactic acid patents have been disclosed. The application of polylactic acid covers many fields such as medical treatment, packaging, equipment manufacturing and material synthesis.
"Industrialization of polylactic acid as the most mature, yield the largest and the most widely used, the lowest price the biological basis of plastic, the most hope is the future shake the status of petroleum base plastic traditional degradable materials, also will become the main force of bioplastics." "Said zhen guangming, a visiting professor at nanjing university of technology and jiangnan university.
Throughout the world, few enterprises can produce polylactic acid on an industrial scale. NatureWorks is the largest company in the world. The current production capacity is 140,000 tons per year and there are plans for further expansion.
Professor ZhenGuangMing former NatureWorks's chief adviser, when it comes to the global market size of poly (lactic acid) (PLA), he said, at present there is no exact data on a global scale, but certainly more than NatureWorks original smaller one production capacity of 70000 tons. Japanese customs import data show that in 2009 the Japanese market of about 7000 tons of poly (lactic acid) (PLA), assuming that the Japanese market is 1/5 ~ 1/10200 of the global market for 9 years global total market between 50000 and 80000 tons of poly (lactic acid) (PLA), due to the growing polylactic acid (PLA) in recent years the global market, global market poly (lactic acid) (PLA) in 2010 must be more than 2009. The global polylactic acid market is expected to reach more than one million tons by 2020.
The production level of enterprises is not uniform
Facing the increasing global market demand, what is the status of China's polylactic acid market? The reporter understands in the interview process, polylactic acid (PLA) although the wide prospect of market, but production of poly (lactic acid) (PLA) is still in its infancy in our country, not only has very few number of projects completed, and the production scale is not big, industry layout are more scattered, relatively short term is difficult to scale. However, with the gradual expansion of the polylactic acid market and the gradual introduction of thousand-ton and 10,000-ton projects, the industrial scale is expected to rise to a new level.
According to ZhenGuangMing, domestic producers of poly (lactic acid) (PLA), the sea is group a larger manufacturers, the company developed a new type of polylactic acid has entered the stage of industrialization, the annual output of 5000 tons of polylactic acid ZhongShiChang running, plans to build ten thousand tons of industrial factory.
Shenzhen guanghua weiye industrial co., LTD. Is also a large scale, currently in the pilot scale, is expanding the 10,000-ton factory. In addition, the enrichment of nantong keeping biological engineering co., LTD., yunnan biological materials technology co., LTD., henan PiaoAn group, the Yangtze river chemical fiber co., LTD. And the Chinese academy of sciences changchun applied chemistry, cooperative enterprises and so on also have polylactic acid production line, the scale is relatively small, but has a different degree of expansion plans.
Through the investigation of the projects under construction in China, the reporter found that many enterprises are building production lines of 1000t scale. With JieLiang biological material co., LTD. Shanghai by tongji university and Shanghai new microorganism was established, the company adopts "one-step" technology of tongji university, poly (lactic acid) (PLA) is currently built thousand tons polylactic acid production line; Jiangsu dominant group announced that can produce thin film, fiber, and other levels of general-purpose, poly (lactic acid) (PLA) is the construction of 1000 tons/year production line, the future construction of 10000 tons/year polylactic acid (PLA) film, packaging production line; Jilin economic and technological development corporation to the development of polylactic acid fiber by lactic acid after polymerization, melt spinning and dry spinning, at present the company yearly produces 5000 tons of corn fiber poly (lactic acid) (PLA) project has been set up.
In addition to the above projects already built and under construction, many enterprises in China have announced plans for the proposed projects, many of which are of large design scale, even up to 10,000 tons. Such as jilin grain group purchasing and distribution co., LTD., plans to build 50000 tons of polylactic acid production line, the scale of chongqing bo fly biochemical products company plans to build 5000 tons/year L - lactic acid and the polylactic acid (PLA) 5000 tons/year project, shandong rural part and grain corn processing co., LTD., plans to build 20000 tons/year lactic acid, 10000 tons/year L - lactic acid and the polylactic acid (PLA) 4000 tons/year project, qinhuangdao le Hua starch co., LTD., polylactic acid (PLA) plans to build 20000 tons/year production line, and new synthetic fiber technology development co., LTD. Jinan planned 10000 tons/year project and huayuan group, poly (lactic acid) (PLA) plans to build 20000 tons/year project such as poly (lactic acid) (PLA).
