In recent years, the rate of waste tires produced in China every year is increasing by 8% -10%. According to statistics, in 2010, the production amount of waste tires in China is about 2.5 hundred million, the recovery utilization rate is only about 50% and is less than 30% of that of developed countries in the west, huge resource waste is caused, and meanwhile, in some places in China, the waste tires are still subjected to original treatment methods such as burning and landfill, and even are discarded randomly, so that black pollution is caused. The waste tires are toxic and harmful solid wastes, have strong heat resistance and degradation resistance, and can not be degraded after being buried in the ground for 100 years. The current situation in China is that more than 700 million tons of rubber are consumed each year, more than 70 percent of natural rubber and more than 40 percent of synthetic rubber need to be imported. Since 2004, the natural rubber self-sufficiency rate in China is lower than the 1/3 strategic safety warning line determined by China, and is reduced to less than 25% at the present stage. The recycling of the waste tires can effectively solve the general demand contradiction, such as: firstly, the asphalt is directly crushed to be made into rubber powder for paving a highway, so that a large amount of asphalt can be saved; secondly, the reclaimed rubber is produced through desulfurization, is used for producing rubber tubes, rubber mats and the like, and can also be added into a newly-manufactured tire according to a certain proportion, so that a large amount of natural rubber and synthetic rubber can be saved; thirdly, decomposing important chemical raw materials such as heavy oil, carbon black and the like in a pyrolysis mode.
