Recently, the "Key Technology for the Industrialization of Biodegradable Plastics" has been listed as a key project of the National Science and Technology Support Plan for the "Eleventh Five-Year Plan" period. The state will allocate 30 million yuan to support relevant research institutes to focus on the development of this technology. The Ministry of Science and Technology requires that the project apply for 5 to 8 international patents within 3 years and apply for 12 to 16 Chinese invention patents.
Biodegradable plastic is a biomass-based resin produced using biotechnology. It is a type of new environmentally-friendly basic raw material that can be fully degraded to carbon dioxide and water. It can replace petroleum-based plastics, thereby reducing oil resources. Dependency. Experts believe that the status of biodegradable plastics should be higher than biofuels, biodiesel and other biomass fuels.
According to reports, the key technology development projects for industrialization of biodegradable plastics, which will be supported by the country, will mainly complete the industrial production of 10,000 tons of carbon dioxide-based plastics, the industrial production of 10,000 tons of polylactic acid, and the production of 1,000 tons of polyhydroxyalkanoates. Industrialization, production and application of 10,000-ton konjac glucomannan, development and application of biodegradable plastics for food packaging, medical evaluation of biodegradable plastics, and research and development of medical products. The overall goal of the project is to research and develop key technologies for the continuous industrial production of three types of typical biodegradable plastics, such as carbon dioxide-based plastics, polylactic acid, and polyhydroxyl acid esters, which have different temperature resistance properties, and establish industrialized demonstration production lines to form Complete set of process packages; through the improvement of thermal and mechanical properties of biodegradable plastics, the preparation technology for biodegradable plastic special materials is formed, breakthroughs in the key processing technologies of medical and food packaging and other products; at the same time, biodegradable plastics for medical and food packaging Safety and life cycle to carry out systematic research, establish an evaluation system, promote the establishment of relevant national standards, accelerate the application of biodegradable plastic products on a large scale.
Experts said that the main measures to reduce costs are two aspects, one is to reduce the cost of biomass raw materials, the second is to reduce costs through biochemical technology. These will be the focus of future scientific research.
