Plastics are almost a category of synthetic materials that cause the most environmental pollution. China is one of the ten largest producers and consumers of plastic products in the world, and plastic waste pollution has a long history. As early as ten years ago, the treatment of "white pollution" has become an important issue of concern to academia and industry. With the development of material technology, degradable synthetic materials are frequently reported. Petroleum and biomass are the two main raw materials for making biodegradable materials. Using petroleum refining and petrochemical technology, special monomer raw materials such as succinic acid, adipic acid, butanediol, etc. can be synthesized to prepare biodegradable polymers, and then biodegradable polyester materials can be synthesized through polymerization technology. It can be completely biodegradable, but our commonly used beverage bottle PET materials and polyester shirts are not biodegradable. Is there a degradable material that can achieve the same function as that of plastic products, which is cheap, good in shape, hard to produce bacteria, mildew, and moisture? Is there a completely degradable technology? The answer is: yes. Technically, degradable materials that can achieve the same function as plastics are completely achievable. Recently, good news came from Changchun Yinghua, Chinese Academy of Sciences! The researcher Wang Xianhong's team turned carbon dioxide into "waste" as treasure. It took 20 years to realize the industrial production of carbon dioxide-based biodegradable plastics. Carbon dioxide is the main culprit of the greenhouse effect, but it is also a low-cost carbon resource. It can be used as a raw material to synthesize carbon dioxide-based biodegradable plastics. The degradation products have no pollution to the environment and the production cost is low. Since 1997, the Changchun Yinghua Institute of the Chinese Academy of Sciences has begun to deploy basic research on the application of carbon dioxide-based biodegradable materials. It is not difficult in principle to synthesize carbon dioxide-based biodegradable materials. The difficulty lies in how to develop high-activity catalysts to synthesize high-molecular-weight carbon dioxide-based plastics, and through low-cost modification to achieve optimal properties of this substance. Through technical cooperation with multiple enterprises and after repeated trials, the team completed the industrial process design of high molecular weight carbon dioxide-based biodegradable plastics with excellent performance in 2014. This achievement was supported by the National Natural Science Foundation of China's Outstanding Youth Science Foundation, and obtained 2 US patents, 1 Japanese patent, and 27 Chinese invention patents, forming a complete independent intellectual property right. At present, the carbon dioxide-based biodegradable plastic has achieved mass production, with an industrialized production capacity of 50,000 tons per year, which can be used to prepare plastic bags and express packaging. Wang Xianhong said that he would step up efforts to promote marketization. If the scale of industrialization reaches 300,000 tons per year, the cost will be further reduced. At the same time, the mulch made of this material has been tested by the Chinese Academy of Agricultural Sciences and other scientific research institutions for four consecutive years. It is expected to provide a new breakthrough for solving the residual pollution of farmland mulch. Since 2018, the R & D team has continued its efforts. The team has put on carbon dioxide-based biodegradable agricultural mulch for 5000 acres of farmland across the country, and the current farmland trials have been effective. A set of data senses the importance of non-petroleum plastic product technology—— According to statistics from 2014, according to statistics, China uses about 3 billion plastic bags every day, and every ton of plastic produced requires 3 tons of oil. China's external dependence on crude oil has exceeded 68%. According to statistics from the Energy Bureau, in October, China produced 16.09 million tons of crude oil and imported 40.8 million tons of crude oil. Talk about carbon capture and storage technology- Carbon dioxide can be used as a raw material to synthesize carbon dioxide-based biodegradable plastics. To achieve large-scale application, it is necessary to master carbon capture and storage technology. Carbon capture and storage technology (CCS) is an indispensable technology for the future development of all low-carbon energy and industries. Carbon capture and storage technology was first applied on a large-scale power station at the border dam in Saskatchewan, Canada in October 2014. The US power industry also launched two large-scale carbon dioxide capture projects between 2016 and 2017, in Kemper County, Mississippi and Texas. In terms of the scale of carbon capture and storage projects, there are currently 22 large-scale projects in operation or under construction in the world, with a total capture of 40 million tons of carbon dioxide per year. The projects cover such as gas processing, power, fertilizer, iron making, and hydrogen production ( Refining) and chemical industries. These projects are mainly located in North America, and most of the captured carbon dioxide is flooded and stored, demonstrating the feasibility of carbon capture and storage technology. Throughout the development of various countries, the Japanese government is working with industry technology providers to find suitable storage sites and review and test the economic feasibility of carbon capture and storage projects; the Korean government ’s carbon capture and storage plan includes large-scale carbon capture and storage demonstrations within a specific cost range Projects and subsequent commercial carbon capture and storage deployment projects; Australia ’s “Gorgon Carbon Dioxide Injection Project†is the world ’s largest carbon dioxide deep salt injection project; there are currently two large-scale carbon capture and storage projects in the Middle East, mainly in Saudi Arabia, Abu Dhabi. In 2007, Shaanxi Yanchang Petroleum Group launched major research projects such as coal chemical industry carbon dioxide capture and storage. In 2013, Yanchang Petroleum and the Global Carbon Capture and Storage Research Institute (GCCSI) signed the "China-Australia Carbon Capture, Utilization and Storage Integration International Cooperation Demonstration Project". At present, the project has completed the feasibility demonstration of 360,000 tons / year of carbon dioxide capture device and entered the design stage. Carbon capture and storage technology is the only method that can significantly reduce greenhouse gas emissions from industrial processes and is a key technology for the decarbonization of the power industry. Compared with the cost of carbon dioxide capture and storage, although the transportation cost of carbon dioxide is lower, the investment in carbon dioxide transport infrastructure required to support large-scale carbon capture and storage deployment will be huge.
