Resource depletion and low carbon production of polylactic acid
Under the background of increasingly depleted petroleum resources and global promotion of low-carbon environmental protection, bioplastics have unparalleled advantages over traditional plastics in terms of resource utilization and degradability. As a family leader in the bioplastics family, polylactic acid (PLA) is favored by all parties for its good compatibility and degradability.
Polylactic acid, also known as polylactide, is a new type of polyester material produced from lactic acid. As lactic acid is made of corn, cassava and other starches by a microbial fermentation method, and then chemically synthesized to form polylactic acid, polylactic acid is a synthetic bio-plastic material that is resource-renewable.
According to Yang Yijun, chairman of the Innovation Alliance for Low Carbon Biomaterials, the polylactic acid is widely used and can be used to process various plastic products, packaged foods, fast food lunch boxes, non-woven fabrics, industrial and civilian fabrics from industry to civilian use. Can be processed into agricultural fabrics, health fabrics, hygiene products and tent cloths, etc. The market prospects are very promising. Polylactic acid is also widely used in the field of medicine, and can produce disposable infusion tools, surgical-free sutures, bone nails, etc., and can also be used for drug release agents.
Since polylactic acid can be completely degraded after use, it will not cause pollution to the environment, making the development of technology a hot topic of current research. The application of polylactic acid-related patents in recent years has become a clue. The data obtained by the reporter from the search platform of the State Intellectual Property Office revealed that polylactic acid-related technologies are increasingly concerned by scientific research institutes and enterprises. From 1997 to 2010, the total number of patent applications for polylactic acid in the country showed an increasing trend, of which the number reached in 2008. At the most, the number of patent applications for polylactic acid topped the list of biodegradable plastics, accounting for about 38% of the total number of applications for biodegradable plastics. In addition, from the perspective of the application fields of polylactic acid patents that have been disclosed, the application of polylactic acid covers medical, packaging, equipment manufacturing, material synthesis and many other fields.
"Polylactic acid is currently the most mature, most productive, most widely used and lowest-cost bio-based plastic. It is the most promising biodegradable material that will shake up the traditional position of petroleum-based plastics. It will also become the main force for bioplastics." Professor Guangming Guang, a visiting professor at the Industrial University and Jiangnan University, said.
Looking at the global production of polylactic acid, there are few companies that can currently produce on an industrial scale. Nature Works is the largest company in the world. The current production capacity has reached 140,000 tons/year and there are plans for further expansion.
Prof. Guangming Guang, who once served as chief consultant of Nature Works China, talked about the global market size of polylactic acid. He said that currently there is no exact information on the global scale, but it is definitely smaller than the production capacity of 70,000 tons in Nature Works' original production line. According to the Japanese customs' import data, the Japanese polylactic acid market in 2009 was about 7,000 tons. Assuming that the Japanese market is 1/5 to 1/10 of the global market, the global polylactic acid market in 2009 will be between 50,000 and 80,000 tons. In the past few years, the global polylactic acid market has grown continuously. In 2010, the global polylactic acid market will definitely be more than in 2009. The global polylactic acid market is expected to reach more than one million tons by 2020.
Uneven production levels are difficult to achieve
Faced with the increasing global market demand, what is the status of China's polylactic acid market? During the interview, the reporter learned that although the polylactic acid market has broad prospects, the production of polylactic acid is still in its infancy in China. Not only the number of completed projects is small, but also the production scale is small, and the industrial layout is relatively fragmented. Looking hard to scale. However, with the gradual expansion of the polylactic acid market, the 1,000-ton and 10,000-ton projects have been gradually launched, and the scale of the industry is expected to rise to a new level.
According to Xu Guangming, among the domestic polylactic acid producers, the Haizheng Group is a relatively large manufacturer. The new polylactic acid developed by the company has entered the industrialization stage, with an annual output of 5,000 tons of polylactic acid pilot plant operating. Ton industrial grade factory. Shenzhen Guanghua Weiye Industrial Co., Ltd. is not only small in scale, but is currently in the pilot scale and is expanding its 10,000-ton plant. In addition, Nantong Jiuding Biological Engineering Co., Ltd., Yunnan Rich Biomaterials Technology Co., Ltd., Henan Piao An Group, Changjiang Chemical Fiber Co., Ltd. and the Changchun Institute of Applied Chemistry of the Chinese Academy of Sciences also have polylactic acid production lines, which are relatively small, but they are There are different degrees of expansion plans.
Through the investigation of projects under construction in China, the reporter found that many companies are building a 1,000-ton production line. Shanghai Tongjieliang Biomaterials Co., Ltd. was established in cooperation with Tongji University and Shanghai Xinli Microbiology Company. The company uses the “one-step†technology of Tongji University to obtain polylactic acid. Currently, it is building a 1,000-ton polylactic acid production line; Jiangsu Jiuding Group announced that it can produce General-purpose polylactic acid at various levels, such as film grade and fiber grade, is building a 1,000-ton/year production line, and a 10,000-ton/year polylactic acid production line for film and packaging will be built; Polylactic acid fiber to be developed by Jilin Economic and Technological Development Corporation It is made from lactic acid through polymerization, melt spinning or dry spinning. At present, the company has an annual output of 5000 tons of corn polylactic acid fiber project.
In addition to the above-mentioned projects that have been built and under construction, many domestic companies have announced plans for proposed projects. Many of the projects have been designed with a large scale, even on the 10,000-ton level. For example, Jilin Grain Group's Storage and Distribution Co., Ltd. plans to build a polylactic acid production line with a capacity of 50,000 tons. Chongqing Bofei Biochemical Products Co., Ltd. plans to build 5,000 tons/year of L-lactic acid and 5000 tons/year of polylactic acid. Shandong Boxing Xing Grain Cereals Co., Ltd. Processing Co., Ltd. proposed to build 20,000 tons/year lactic acid, 10,000 tons/year L-lactic acid and 4,000 tons/year polylactic acid project, Qinhuangdao Waxy Starch Co., Ltd. proposed to build 20,000 tons/year polylactic acid production line, and Jinan New Syntech Technology Development Co., Ltd. plans to build a 10,000-ton/year polylactic acid project and Huayuan Group plans to build a 20,000-ton/year polylactic acid project.
