Chinese scientists have synthesized plastics that can be self degraded in seawater. Chinese scientists have synthesized a new polyester material that can be self degraded in seawater through dissolution and microbial decomposition. Microorganisms living in water can naturally decompose the plastic into carbon dioxide and water. This revolutionary research achievement will help to solve the acute problem of marine pollution by plastic waste. Mikhail korostikov, a Russian Sinologist and commentator of the businessman, mentioned China's concern about the "green economy" in his commentary for the Russian satellite news agency

the latest achievement of Chinese scientists that the heavy cyclotron framework uses ultra-light carbon fiber composites. The reason is that the garbage collection, recycling and decomposition methods used on land are not suitable for the sea. For example, plastic that is easy to degrade in soil will not decompose in seawater for decades or even centuries. The influence of the sun, salt, ocean currents and organisms can decompose the plastic into small particles with a growth of 5mm. Many albatrosses and turtles develop gastrointestinal diseases after ingesting plastic particles. Scientific research has proved that the horizontal tensile testing machine can test and analyze the mechanical properties of various metal, non-metal and composite materials. More than 90% of seabirds die because plastic particles enter the stomach

one of the most modern scientific solutions for flexible conditioning of handlebars and cushions is the biodegradable technology of plastics. Previously, it was generally believed that bacteria would not decompose and process polyethylene because polyethylene does not exist in nature. But now scientists know the specific bacteria and fungi that can process polyethylene. Experiments by Chinese scientists have proved that the newly synthesized polyester composite can be biodegradable in seawater within a few to hundreds of days, leaving macromolecules that will not pose a threat to the environment

the Institute of physical and chemical technology of the Chinese Academy of Sciences has completed the technical authorization to four private enterprises, allowing them to use new technologies to produce new ecological plastics on a large scale. Three of them have been put into operation successfully, with a total capacity of 75000 tons per year. In addition, at the "pioneer Cup" future technological innovation competition recently held in Shenzhen, this technology ranked among the 30 winning projects

the problem of marine pollution by inorganic wastes does pose a great threat to the environment. After all, it may cause large-scale poisoning of animals, the expansion of high molecular chains into linear groups under the action of the nozzle, and even the complete disappearance of many species. It is conservatively estimated that about 4.8 million tons of plastic waste are put into the ocean every year, accounting for 60-80% of the total amount of marine solid pollutants. At present, plastic wastes are mainly distributed in the North Pacific, South Pacific, North Atlantic, South Atlantic and central Indian Ocean. Experts from the world economic forum also warned that the total weight of global marine plastics will exceed the total weight of fish in 2050. Therefore, the experiments of Chinese scientists are not only extremely urgent for China, but also of great significance on a global scale
