Its plastic products can be completely degraded, and its popularization will cure global white pollution problems.
As we all know, carbon dioxide is a gas, however, Tianguan Group can polymerize it into a fully degradable plastic. On February 26th, the reporter took the lead in the world to achieve the industrialization of the production of fully degradable plastics using carbon dioxide.
The use of carbon dioxide to polymerize into fully degradable plastics is a hot and difficult issue that the world is concerned about. At present, most of the plastic products on the market are made of petroleum as raw materials, which are not only costly, but also are not easily degraded after use and seriously pollute the environment.
In 1997, Tianguan Group cooperated with Sun Yat-sen University to start research on the production of full-scale degradable plastics. At the end of 2003, the group built a 50-ton annual production line and passed the results appraisal organized by the Science and Technology Department of Henan Province. In order to speed up the industrialization process, the group completed the current production line of 1,000 tons in September 2006, and after one and a half years of production tests, it proved that the process is reasonable and it has already possessed industrial production capacity.
This technology uses a catalyst with high activity and high catalytic efficiency to polymerize the carbon dioxide emissions emitted by Tianguan Group during the production of alcohol into a fully degradable plastic (polypropylene carbonate). It is understood that the full degradation of plastic products in the mechanical properties, thermal stability, pressure resistance and other aspects can be comparable to the general plastic products, not only for the low temperature plastic film market, but also the development of disposable lunch boxes, foam packaging materials, children's toys Wait.
According to Du Fengguang, chief engineer of Tianguan Group, the industrialized production line with the largest scale of 5,000 tons/year of degradable plastics put into operation is also at the leading level in the world. On the one hand, this technology can reduce carbon dioxide emissions and save petroleum resources. On the other hand, the aggregated green plastic can be completely biodegradable, can fundamentally solve the "white pollution" as a worldwide hazard, and promote large-scale environmental protection plastics. Providing realism is a typical circular economy technology model.
It is reported that the price of the whole degradable plastic is about 30,000 yuan per ton. At present, the annual demand for this product at home and abroad exceeds 10 million tons, and the total production capacity is less than 10,000 tons, which has broad market prospects.

Waste plastics such as plastic bags, disposable plastic tableware, agricultural films, etc., are commonly referred to as "white pollution." The "white pollution" caused by these waste plastics can only be degraded when buried underground for more than 200 years. It will seriously pollute the soil and groundwater sources. If it is burned, it will pollute the air with toxic gases and seriously destroy people's living environment.
In order to curb "white pollution", on January 8, the General Office of the State Council issued the "Notice on Restricting the Use of Plastic Shopping Bags for Production and Marketing." From June 1 this year, the production, sale, and use of ultra-thin bans are prohibited nationwide. Plastic shopping bag.
