Prediction of the market prospect of degradable polylactic acid

in order to get rid of the dependence on limited oil resources, vigorously developing biodegradable polymers that do not pollute the environment to replace petroleum based plastic products has become a hot spot of current research and development. After years of research, some famous scientific research institutions and enterprises have launched a variety of biodegradable polymers. Among many biodegradable polymers, polylactic acid (PLA), which has just entered the industrial production, has a sudden rise. With its excellent mechanical properties, a wide range of applications, significant environmental and social benefits, it has attracted the attention of the global plastic industry. It is expected that during the period from 2005 to 2010, with the production cost of polylactic acid approaching the cost of traditional plastics and the vigorous expansion of market application, the popularity of polylactic acid will reach a peak

in recent years, breakthroughs have been made in the technological development and industrial production of polylactic acid abroad. In 1997, Cargill company of the United States and Dow Chemical Company jointly established a company to develop and produce polylactic acid. The product is called natureworktm, and the production capacity was only 16000 tons at that time. In November 2001, the company invested US $300million and adopted two-step polymerization technology to build and put into operation a 136000 ton annual unit in the United States, which is by far the largest polylactic acid production unit in the world. The operating rate of PLA plant was 70% in 2002, and it is expected to reach 80% in 2003. After the device was put into operation, the products have been valued by some internationally renowned companies. Coca Cola company and Dunlop Pacific Company have been applied to the production of cups, golf ball packaging and food packaging

reducing costs and improving competitiveness are the problems that need to be solved in the future development of polylactic acid industry. At the beginning of 1998, the market price of polylactic acid decreased from $5000/ton to $2500/ton. At present, the price is 10% - 15% cheaper than that of pet (polyethylene terephthalate). It is expected that the price of polylactic acid will reach the level that can compete with all thermoplastic resins in seven years. Cargill Dow plans to invest US $1billion in the next 10 years and build three more units in 2004, 2006 and 2009 respectively, with a total production capacity of 450000 tons/year. At present, the company is evaluating the engineering construction of the second unit. The plant site depends on the economy and supply and demand. The candidate sites are initially determined in Asia, Europe and South America, and it is planned to be put into operation in 2004. During this period, the company actively transferred licenses, including the construction of polylactic acid production plants in Asia. It is estimated that the global supply will be nearly one million tons in 10 years

Japan is an important application development area and application market of polylactic acid in the world, which is mainly used in packaging containers, agriculture, construction industry, fiber sportswear and bedding, etc. Japan calls biodegradable plastics green plastics. In order to expand market share, Cargill Dow polylactic acid company announced to cooperate with Mitsui chemical company to develop the application of polylactic acid. In the future, it will also cooperate with Japan Zhongfang synthetic fiber, Mitsubishi resin, Eureka Bian Xinchao, deputy general manager of kelili Zhejiang Haizheng biomaterials Co., Ltd.: "Our project has gone from the laboratory to a production capacity of 15000 tons and other companies to carry out cooperative application research and explore new application fields.

it is predicted that in the next few years, the market demand for biodegradable polymers in North America will be strong, with a sales volume of about 1.14 million tons in 2000 and an average annual growth rate of 7% in 2005, which will reach 1.6 million tons, including polylactide 3. The demand for acid to start the experimental machine is nearly 1million tons. At the same time, the market for biodegradable polymers in North America will Bulk packaging materials are mainly used, with a sales volume of 900000 tons in 2000, and the average annual growth rate is expected to be 4.6% in the future; The second largest application field is chemical fertilizer packaging bags, with an estimated annual growth rate of 9.9%, and the sales volume increased from 230000 tons in 2000 to 360000 tons in 2005; Other applications include agricultural film, sanitary products, paper coating, etc

polylactic acid is also a low-energy product, which is 30% - 50% lower than polymers produced from petroleum products. Not long ago, the U.S. Department of energy awarded Cargill Dow a $2million prize for fermentation research using renewable resources. Another 2million US dollars is used for the research on the fermentation of polylactic acid and other products from grain fibers, plant stems, etc. It is expected that before the non renewable oil resource depletion period, the market price of oil and its derivatives will soar, and renewable products will become a global consumer goods in short supply. In this way, it brings a once-in-a-lifetime market opportunity and great consumption potential to polylactic acid. According to statistics, the world's plastic consumption in 2000 was about 115 million tons. If the consumption of petroleum based polymers is replaced by 10% - 20% in 10-20 years, the world's demand for polylactic acid will reach 11.5-23 million tons per year
