The growth of the famous American consulting company, if the stern Sullivan (frost), according to the report published in November 2011 research day by day strengthens along with the people environmental protection consciousness and the plastic limit and the implementation of the law regulations, recycle the biodegradable plastics application prospect is very broad, especially biodegradable plastics, will gradually replace the traditional non-biodegradable plastic and gain more market share.
Plastic is a resin as main ingredients, appropriate to join (or without) additive (packing, plasticizer, stabilizer, pigment, etc.), can be in a certain temperature, pressure and plastic molding, and finally the product can keep unchanged shape a kind of polymer materials at room temperature. The main types of plastic resins are PE (polyethylene), PP (polypropylene), PS (polystyrene), PVC (polyvinyl chloride), PET (polyethylene terephthalate) and so on.
Because of the plastic material has good forming performance and corrosion resistance, waterproof and the characteristics of light, made of plastic has a very wide range of applications, can be used in both ordinary living goods packing, and can be applied in the industrial field, such as auto parts, building materials, electronic communications, etc. In 2010, the global demand for plastic resin for more than 220 million tons, China's demand for more than 70 million tons of plastic resin, the global share of about 33%, the largest plastics consumer in the world.
According to the definition of ISO (international organization for standardization), degradable plastics refer to plastics that can undergo significant changes in chemical structures under certain environmental conditions and thus degrade naturally. Way according to the degradation can be divided into light degradable plastics, biodegradable plastics, light/biodegradable plastics, and other degradable plastics, etc., in which light degradable plastics is refers to the incorporation of photosensitizer in plastic, gradually decomposition of plastics under the sunshine, due to the toxicity of photosensitizer itself has, is now rarely used. Under the action of microorganism, biodegradable plastics can be completely decomposed into low molecular compound plastics. According to degradable plastics additive composition, degradable plastics can be divided into starch based biodegradable plastics, PBS and PVOH petroleum-based plastics, PLA (polylactic acid) degradation plastics and PHA (polyhydroxy fatty acid ester) degradable plastics.
The following table is a comparison of the main biodegradable plastics performance:

Name raw materials advantages and disadvantages
Starch based plastic corn, potatoes or wheat and additives with good film forming ability; Good oxygen barrier property; Compared with other bio-plastics, the price is low and unstable, and it is sensitive to water. Low tensile strength; A blend of petroleum-based polymers is often required to enhance performance and not degrade completely
PLA starch or sugar extracted from potatoes are highly accepted in the market. In the course of commercialization; Good transparency; Good tensile strength and poor heat resistance; Poor mechanical performance limits its application
PHA glucose can be degraded completely by bacterial fermentation without compost. Excellent performance; Wider application costs higher; The current industrialization is not enough
PBS plastic oil can enhance the performance of starch based plastics, which depends on oil and is sensitive to water. Degradation in the air limits its use
Excellent film forming ability of PVOH plastic oil; Good emulsifying and bonding properties depend on oil and are sensitive to moisture
Market situation and competition pattern
With the increasing popularity of environmental protection packaging, the demand for degradable materials is increasing. The global market for biodegradable plastics reached 530,000 tons in 2010, up 23.1% from 2009. Global demand for degradable plastic resins is expected to grow at a compound growth rate of 24.9% over the next five years, reaching 1.61 million tons by 2015.
Biodegradable plastics are an important component of biodegradable plastics. In 2010, they accounted for about 70.0% of the global market of biodegradable plastics and consumed a total of 370,000 tons. It is expected that the biodegradable plastics market will show a compound annual growth rate of 25.8% in the next five years, reaching 1.17 million tons by 2015.
The world's leading manufacturer of biodegradable plastics is driving the growth of the market for biodegradable plastics. NatureWorks cargill affiliated companies in the United States in 2006, the PLA polylactic acid productivity increase to 140000 tons of plastic, which resulted in the production of biodegradable plastics on the market and the surge in demand, degradable plastics market growth rate of more than 50% in 2006. Degradable plastics consumption is also affected by the global recession in 2009, fell to 6.4% in 2009, the growth rate of degradable plastics, however, as the global economic recovery, the market picks up, step by step in the forecast period, degradable plastics market will be steady growth.
The most widely used plastics industry PLA polylactic acid degradable plastic is plastic, due to its stability is better, can compost degradation in nature at the same time, many enterprises in Europe, America and Japan have stepped up to the PLA plastics research and development and production, in the United States Natureworks in the industry in a leading position, has a production capacity of 140000 tons, Germany basf group, Japan's mitsui corporation, and the Netherlands oprah g group has more than ten thousand tons of PLA capacity. China now has about 5,000 tons of PLA production capacity in zhejiang haizheng biotechnology group and guangzhou goldilocks technology co., ltd. respectively, which are strong in domestic PLA manufacturers.
Starch based biodegradable plastics is earlier biodegradable plastics, compared with the PLA degradable plastics, the production process is simple, the world's major manufacturers, including Italy Novamont company, has a production capacity of 75000 tons, Cereplast Biotec company in Germany, the United States, Japan's corn starch co., LTD is a typical representative of the industry, etc. Representative companies in China mainly include wuhan huali environmental protection technology co., LTD and zhongjing colin new material co., LTD.
PHA degradable plastics have the best performance among biodegradable plastics. At the same time, due to its high cost and complicated production process, PHA degradation plastics are still at the initial stage of the market. In 2010, the global PHA production capacity was less than 80,000 tons, among which Metabolix in the us had about 50,000 tons of production capacity, accounting for over 60% of the market. Chinese enterprises in the production process of PHA, and research and development on the same before go toward, rhyme biological technology co., LTD. Tianjin countries with 10000 tons of PHA production capacity, ningbo tianan has production capacity of 2000 tons, shenzhen meaning to may have a production capacity of 5000 tons of biological technology co., LTD. Kaneka companies in Japan, the Brazilian PHBIndustrial company is also a typical representative of PHA industry, these companies are PHA the drivers of the industry, although the application of PHA is relatively limited at present, Metabolix annual actual sales volume is not more than 100 tons, but as the future downstream application gradually expanded, especially in the film packaging, agricultural films, eating utensils, non-woven industry such as further mature, the application of PHA market potential is tremendous.
Market recommendations
There is no doubt that in the next few years, the global biodegradable plastic will present rapid growth, degradable plastics enterprises should strive to do the following aspects, thus gaining advantage in competition and the traditional plastic, obtain a higher market share:
1. Pay attention to the research and development of downstream applications, and develop products with good performance and stability in the film packaging industry, agricultural film industry and other industries.
2. Reduce costs, so as to narrow the price gap with traditional plastics, and obtain high cost performance and competitiveness.
3. Pay attention to marketing, can exchange and biodegradable plastic exposition to the consumer and the downstream procurement suppliers develop biodegradable plastic raw materials of good performance and environmental benefits, at the same time, to the promotion of the government, to strengthen the enforcement of plastic limit.
