With the expansion of the domestic automobile market, the safety, environmental protection, resource problems caused by scrap cars and the broad prospects of the automobile remanufacturing industry have been paid more and more attention, this paper analyzes the current situation of scrap vehicles in China, compares the characteristics of scrap vehicle management methods in developed countries, and puts forward some suggestions on the recycling and utilization of scrap vehicles in China. The social impact of scrap automobile on automobile industry is not only the pillar industry to promote the development of national economy, but also the key industry with high consumption, high emission and influence on environmental pollution. 2009 China's cumulative production and sales of double super 13.6 million vehicles, the total car ownership has exceeded 70 million vehicles, according to about 7% of the annual scrap, the weight of the end-of-life car is more than 7 million tons.
It is predicted that China's auto sales will reach 16 million vehicles in 2010, and the number of automobile scrap is also growing rapidly, bringing many problems to the society. 1, scrap cars on the road to the excessive operation of the harm, domestic cars after reaching the end of life, often illegally extended the use of time. Excessive operation of auto parts, in the automotive operation of reduced reliability, will directly lead to brake failure, steering and engine and other parts failure, will make the vehicle's operational stability is poor, easy to run; These overused end-of-life vehicles, in the use of the process, the function of decline, safety risks increased.
In the 2008, there were many traffic accidents caused by the excessive use of cars in various regions of China, which caused great losses to the parties and society. In addition, the excessive use of end-of-life vehicles, all parts wear serious, fuel consumption is greater than normal level, emissions can not meet the normal standards, oil consumption increased, resulting in waste of resources, atmospheric environmental pollution and other problems.
Ching, vice president of the Economic Development Research Branch of the China Automobile Engineering Society, has said that after becoming the "world's largest car park", China is turning into "the world's largest auto dump" for the increasingly serious problem of car scrapping. 2, scrap car re-return into society, the harm is great, because the scrap vehicle itself has not met the road driving conditions, was again modified into the road, its car itself performance changes, the safety factor greatly reduced. Scrap Vehicle heavy flow society an important way is "illegal assembly", in recent years, by the scrap car assembly assembled on the road caused by traffic accidents occur from time to time, to the people's lives and property safety and social stability caused serious harm.
According to the information, in nearly 3 years of traffic accidents in China, 13% is due to the use of shoddy and scrap auto parts, illegal loading of the safety performance is completely not guaranteed, is one of the main causes of traffic accidents. 3, scrap cars on environmental pollution, automobile production process contains a large number of harmful substances, in addition to the main manufacture of raw materials steel, pig iron, a large number of rubber, plastics, non-ferrous metals are extracted, arsenic, selenium and so on are also found in automobiles. In the process of non-correct treatment of automobile after scrapping, the pollution of exhaust gas, waste oil, waste battery and scrap parts is very serious to the environment. Improper handling of waste oil, scrapped old batteries and scrapped parts in the car will cause great pollution and damage to the surrounding environment. In addition, air conditioning refrigerant-HCFC leakage of direct emissions, will cause damage to the ozone layer of the atmosphere, posing a serious threat to human health.
