Comprehensive utilization of resources of discarded tires

China is the world's rubber consumption power, the shortage of rubber resources. Since 2002, 3 years in a row over the national consumption of rubber abode of the United States in the world. By the year 2004, rubber consumption reached 4,200,000 tons, of which 70% used in the production of tires.

Used tires and tires with more ways to recycle. Used tires can be a number of renovation, refurbishment of a 9.00R20 tire specifications, rubber conservation 9kg, carbon black 4kg, steel cord 3.4kg, oil 18kg, steel 1.75kg. U.S. tire renovation in 2004 of about 28,000,000, the new tires and tire renovation of a ratio of 9:1. The main tires used in the production of powder or as a fuel. In the past, tires approach is the main landfill or burning. Due to the refractory rubber, rubber was the landfill and long-term presence in the environment, the formation of environmental pollution. In addition, the combustion method will lead to serious secondary pollution. The two methods will lead to waste of resources. Now, the parties concerned to develop a low-temperature frozen powder production of the new technology, more and more of the powder can be used to produce a new tire, manufacturing modified asphalt roads, water and the production of rubber materials.

From China's automobile industry, such as the development trend of related industries, waste tire recycling resources and broad prospects. In 2004, our cars 30,000,000, in 2010 is expected to reach 70,000,000, tire production capacity of 300,000,000.

China's waste tire recycling compared with the developed countries there are still large gaps. Of the main problems: the low rate of refurbishment of used tires, in 2004 China's new tires for the renovation of the rate of 20:1, and more focused on refurbished goods in trucks for cars, aircraft tires, and so did the basic renovation; domestic production of rubber tires just Start, there is no new industry, dozens of manufacturers, powder production was only more than 30,000 tons. If, in accordance with the current prospects for the development, the demand for rubber by the year 2010 at least 350,000 tons; China's recycling of discarded tires to support the policy and management is relatively backward. At present, China is no waste tire recycling management, nor the formal establishment of the recycling system. So far there is no recycling of discarded tires to the specific legislation to deal with the discarded tires on the lack of preferential policies to foreign discarded tires are free to use, there are government subsidies and implement duty-free policy. But not only China's duty-free, the tax rate is also higher than that of other processing industries; China's recycling of discarded tires are generally small-scale production, low self-improvement, development without staying power. Most of the renovation of the tire business equipment level is not high, the weakness of the technology. China's resources, coupled with sporadic spread of discarded tires, and its recovery, processing, transportation costs, production and management difficulties, the waste tire recycling industry was hovering at a low level state.

While China's comprehensive utilization of resources of discarded tires and there is a big gap between the developed countries, but also a potential gap. To promote the comprehensive utilization of resources of discarded tires, learning from successful foreign experience, combined with the actual situation in the ongoing technical, management and policy innovation. As soon as possible to "waste tire recycling management", recycling of discarded tires to use the legal system step by step into the management of the track; establish and improve the waste tire recycling network and mechanism in the region focus on recycling of discarded tires, classification, the early processing and re - The use of distribution; research to encourage the development of recycling discarded tires economic policy, recycling of discarded tires to speed up the industrialization process, not only to find the resources to make full use of discarded tires, and there was no secondary pollution of the use of a variety of ways to build a conservation-minded society and Accelerate the development of circular economy, open up a new breakthrough.
