Degradable plastics industry or national policy support
Degradable plastic give aid to policy is expected in the second half came on stage in succession, planning to support the object contains biomaterials, fully degradable materials, support means includes value-added tax return, tax relief, key project procurement. The Ministry has related policy documents referred to the housing construction department, relevant ministries and commissions for countersignature. Is expected to impact on the listed companies related to constitute a good. According to the current understanding of the domestic listed companies, only Fu Xin Pharmaceutical and technology with degradable plastics production. Among them, Fu Xin pharmaceutical production capacity twenty thousand tons, blonde technology one kiloton test line. Affected by this news, Fu Xin pharmaceutical trading day to close at 26, blonde technology in the market fell 0.88% in the case of closed only down 0.17%.
Degradable plastic industry grows the current situation
Biodegradable plastics research began in the last century 70 's England, enter on century 90 time degradation plastic application had entered the relatively stable development period. At present, Europe and the United States on the developed countries in the relevant industrial policy give aid to below, there is a considerable development.
According to the study, since 2002, the United States market on degradable plastic demand of more than 15% annual rate of growth, especially for biodegradable plastics demand is growing by about 17% a year, is expected to 2012, the United States market demand for degradable plastics will reach 720000000 pounds (equivalent to about 326600 tons ). Member of the European Union, Britain, Germany, Italy, Holland and other countries in degradable plastics research and application, also get a lot of progress. The European Union is revised guidance document, promote the use of biodegradable plastic products. Research and application of degradable plastics in China began in the last century 80's, at the same time, started the industrialization of production and try.
At present, used in the production of biodegradable plastic products the main material and technology has the following kinds:
A polycaprolactone ( PCL ): the plastic has good biodegradability, melting point of 62 DEG C. Decomposition of its microbial widely distributed in the festivity or anaerobic conditions. As biodegradable materials can take it with starch, cellulose materials are mixed together, or with lactic acid polymerization using.
Two is a polybutylene succinate ( PBS ) and its copolymers: PBS ( with a melting point of 114 DEG C ) as the base material of various molecular weight polyester technology has reached the level of industrial production. Mitsubishi Chemical and Showa polymer companies have begun to industrialized production, about 1000 tons of scale in. The Chinese Academy of Sciences Institute of physical and chemical research on poly butylene succinate copolyester synthesis research. At present, the Chinese Academy of Sciences Institute of physical and chemical research is to build an annual output of 10000 tons of production lines PBS, Guangdong blonde company built with an annual output of 1000 tons scale of production line.
Three is the polylactic acid ( PLA ): the United States of America Naturework company in improving the poly lactic acid production technology has made positive and effective work, development of the corn in glucose production by fermentation of lactic acid, the annual production capacity has reached 14000 tons. The Japanese company UNITIKA, R & D and production of many kinds of products, including canvas, tray, tableware and so on in the Aichi Expo in Japan is widely used. China's current industrialization of Zhejiang Marine Biological Degradation Plastics Corporation ( scale of 5000 tons / year ), are pilot units Shanghai kit with good biological material limited company, Jiangsu Jiuding group.
Four is the polyhydroxyalkanoates ( PHA ): at present industrialized production for the United States and Brazil and other countries. The current domestic production unit of Ningbo Tian biological material limited company ( the scale of 2 tons / year ), is pilot unit has South Jiangsu Group Limited company, Tianjin country rhyme biotechnology limited company.
Five is the aliphatic-aromatic copolyester: Germany BASF companies manufacture of aliphatic and aromatic random copolyester ( Ecoflex ), the current production capacity of 140000 tons / year.
