Recycling plastic in scrapped cars

Plastic is a material that is difficult to spontaneously ignite and decompose, and some modified plastic materials have a longer life. If it is treated by incineration, it will cause serious air pollution. The number of cars used for scrapping is a matter of years. With the increase in the number of vehicles in the world, the amount of waste plastics disassembled from cars can be imagined. Therefore, how to deal with these plastic parts has become a headache. The greatest benefit of using plastic to make automotive parts is to reduce the weight of the car and improve the performance of certain parts of the car. But it is also the unique characteristics of plastic components that bring about extremely difficult recycling problems, the biggest of which is environmental pollution.

The best way out for scrapped plastics is, of course, recycling and reuse, but the recycling process is very complicated. Even in some countries where recycling technology is advanced, the recycling and recycling of plastic parts are still under research and development. At present, foreign countries still mainly use the way of burning and utilizing heat energy to dispose of used automobile plastic parts. Through certain cleaning devices, waste gas and waste residues that cannot be used are cleaned. However, several years ago, Japan and European countries have separately put forward requirements for the use of waste plastics for automobiles, and have set specific years. As the government of the developed countries in the automobile industry attaches great importance to the recycling of waste materials including plastics and rubber, the actual utilization rate of automotive waste plastics reached about 85% in 2000 and is expected to reach 95% by 2015. . At present, the recycling, regeneration, and utilization technologies of automotive waste plastics have become a hot spot in foreign countries and have gradually become a new industry.

In fact, improving the comprehensive technology of materials application and scientifically selecting materials for auto parts, especially the selection of new products, is the basis for the recycling and recycling of automotive plastics. The variety of auto plastics selected tends to be centralized and unified, which facilitates future classification and recycling after end-of-life and overall recycling. Currently, the concept of comprehensive application of materials has been advocated in foreign countries, and the utilization rate of materials has been fully increased, and it has been applied to automotive plastic materials. In the practice of design and production, our country's application and practice in this area is almost blank.

To establish the environmental protection concept of automotive plastics application technology, government emphasis is the key to the key. In China, due to the deviation of the concept of environmental protection and the lack of awareness of environmental protection and the importance of environmental protection in some departments, the issue of the recovery, regeneration and utilization of plastics in end-of-life vehicles has not yet been mentioned to a certain degree, and a considerable part of them are still burning. Backward methods to deal with automotive waste plastics have caused considerable air pollution problems. Starting from the long-term interests, from the perspective of protecting the environment, we must pay attention to pollution caused by the use of materials such as waste plastics and rubber. At present, environmental pollution caused by scrapped plastics removed from automobiles has become increasingly serious in China. The relevant national authorities should promptly adopt measures and formulate relevant policies to solve this problem, and improve energy-saving and material-saving regulations as soon as possible, and recycle waste metals. Regulations on waste plastic products such as plastics and rubber, and through certain encouragement policies to support the recycling and recycling of waste plastics and rubber-like materials used in automobiles, so as to make the types and age of contaminated products such as waste plastics used in automobiles. Limited to more scientific and more reasonable norms.

The research, design, production, and distribution departments of China's auto industry and related industries should endeavor to carry out the research and development of automotive waste plastics recycling, recycling and other technologies, and strive to make automotive waste plastics no longer be polluted in a relatively short period of time. Environment, problems that plague people's environmental protection and sustainable development.
