How to deal with plastic products

as early as 1985, the per capita consumption of packaging plastic in the United States had reached 23.4 kg, Japan 20.1 kg, Europe 15 kg, while China's per capita consumption of packaging plastic was 13 kg by 1997. However, developed countries realized the harm of "white pollution" earlier and took a two pronged approach of recycling and substitution to prevent and control, basically eliminating the harm of "white pollution"

in some developed countries, people have a strong awareness of environmental protection, few people litter casually, and the national domestic waste harmless disposal rate is also high. Take the United States as an example. Before the 1980s, waste plastics were mainly landfilled. It was found that plastics did not degrade for a long time and were converted to recycled waste plastics. At present, a strict classification and recycling system has been established, and the recycling rate of waste plastics is high. These countries have also enacted special laws to ensure the recycling of waste plastics. The United States has introduced the "resource protection and recovery 5. Recovery after sample fracture act", and 10 states including New York have introduced subsidy recovery deposit systems. Japan's renewable resources law, energy conservation and renewable resources support law, and packaging container recycling law all clarify the respective recycling obligations of manufacturers, sellers and consumers. The packaging regulation of Germany links the obligation of recycling, utilizing and disposing waste packaging materials with the right to produce, sell and consume goods

for non degradable plastic bags, which are very difficult to recycle, the foreign response is to develop alternative products. The technology of producing degradable plastic products in the United States, Britain, Japan and other countries is mature, but if the microcomputer has strong functions and can be printed directly, the product is expensive, which is much higher than that of non degradable plastic products

according to China's national conditions, how to deal with this problem at present. Beijing has adopted the strategy of "recycling first, supplemented by substitution" to control "white pollution", requiring units and individuals that produce and distribute non degradable disposable tableware to be responsible for recycling. However, experts pointed out that the purpose of replacing plastic with paper is to eliminate white pollution, but even paper lunch boxes must also take the road of recycling, because its degradation also takes some time. Replacing plastic with paper still requires residents' awareness of environmental protection and the government's management according to law

this innovative technology of the Chinese Academy of sciences directly attacks the pain points of the packaging industry such as leakage and wear. The trick of the Guangzhou Institute of chemistry is to make it "modified" - introduce the genes of other substances into the molecular chain of polystyrene plastic to form a new molecular structure, so as to make the plastic "clean up" into a new material - water reducing enhancer. When mixing concrete, if 0.5% - 1% water reducing and reinforcing agent is added, the mixing water required for concrete can be greatly reduced, and its fluidity and strength can be improved at the same time. Liaobing, the project leader, said that the cost of water reducing enhancer is 2600-3000 yuan/ton, while its market selling price is 8000-9000 yuan/ton

another way to treat waste plastics is to "return to the original form" - plastics were originally synthesized from petroleum. After cracking the waste plastics with macromolecules by chemical methods, they can be reduced to small molecules of gasoline and diesel. There is a machine near the laolaolong landfill in the suburbs of Guangzhou. It eats plastic and spits out fuel. It is said that this group of devices has a great appetite, and can eat more than 1 ton of plastic waste a day

people with advanced ideas have spontaneously started to act. Last year, we saw such a scene in the flower gardening market located on the west side of Beijing DABEIYAO consumer market: long queues of people carrying waste plastic bags and waste batteries came to the market to exchange flowers, which was an innovation. Coincidentally, Beijing Yanqing County recently issued a new regulation that the government funded the purchase of ultra-thin plastic garbage bags: the supply and marketing cooperatives in the towns and townships are responsible for the unified purchase at the price of 8 yuan per kilogram, and then handed over to the municipal administration department for unified disposal. As soon as this regulation was issued, it immediately set off an upsurge of picking up garbage, and achieved remarkable results. People began to pay attention to the ultra-thin plastic garbage bags that are usually discarded casually, and many residents picked up garbage bags everywhere. It is understood that in just one week, 11 Purchase sites in the county have purchased nearly 3 tons of garbage bags, which are piled up like a hill

the practice of Yanqing County in Beijing has given us an enlightenment: at present, the "white pollution" can no longer be ignored. To solve this problem, the government should come forward and suggest the establishment of a fund dedicated to the control of "white pollution". The fund supports the "white pollution" treatment scientific research project to solve the problems in the recycling of plastic products; Secondly, in the absence of effective treatment at present, it is more economical to purchase plastic bags with funds and then deal with them in a centralized manner than to dig them out of the ground and deal with them in the future
