Carbon dioxide synthesis of biodegradable plastic world development progress

Carbon dioxide based polymers based on carbon dioxide and hydrocarbon raw material copolymerization and become the new plastic raw materials. The carbon dioxide content is 31% ~ 50%, can greatly reduce the upstream raw materials of hydrocarbon oil consumption. After use of plastic waste, carbon dioxide based polymers can be achieved by recycling, incineration and landfill in a variety of ways, such as processing, waste carbon dioxide based polymers can be like common plastic recycled for reuse; During incineration only generates carbon dioxide and water, don't smoke, does not cause secondary pollution; When landfill treatment, but in a few months the degradation. Carbon dioxide degradable plastics is a completely biodegradable plastics, can be completely degraded in the natural environment, and can be used for disposable packaging materials, tableware, fresh materials, disposable medical materials, plastic, etc. Carbon dioxide degradable plastics as environmentally friendly products and high-tech products, is becoming a research hotspot in the world today. Using this technology in the production of degradable plastics, not only will the industrial waste gas carbon dioxide into the environmentally friendly biodegradable plastics, and avoids the traditional plastic products secondary pollution to the environment. The development of it, not only expanded the function of the plastic, and to a certain extent to increasingly depleted oil resources is a supplement. Therefore, carbon dioxide production and application of degradable plastics, no matter from the environmental protection, or from the perspective of the regeneration utilization of resources has important significance. The United States, South Korea, Japan, Russia and Taiwan scientists in the field of carbon dioxide based polymers in China carried out extensive research and development work.
