Analysis on the Market Situation of Domestic Waste Tire Recycling
Tire is one of the important parts of the car, it is directly in contact with the road, and together with the car suspension to ease the impact of car driving, to ensure that the car has a good seat comfort and driving comfort; to ensure that the wheels and the road has good adhesion, improving the cars traction, braking and trafficability characteristic; bear the weight of the car. The important role of tires in the car has been paid more and more attention.
According to the source, the current domestic waste tires are mainly divided into two categories - passenger tires and commercial tires, among them commercial vehicles tires are mainly large truck tires. Relatively speaking, the overall production of passenger tires change, mainly change with the change trend of the number of passenger cars, the market is running normally. But there are more problems of large trucks, for a long time, the domestic logistics industry is affected by many factors. Overrun and overload problems are more prominent, and it is often seen that on the road the overlong truck is assembled with more than 20 tires, carrying more than 100 tons.
Overrun and overload make tire life greatly reduced, that is also an important reason for the significant increase of waste tires in annual production. It is estimated that each year the number of current domestic waste tires of large trucks are close to 200 million, especially in the past two years, infrastructure construction increased, the situation even more serious. With the development of the domestic logistics industry, this situation is showing a growing trend.
After the generating of waste tires, because of its main component is rubber and carbon black, its corrosion resistance is very strong. How to effectively deal with and make use of waste tires is a matter of general concern.
However, most of the waste tires are effectively reused. Of which 46% of the waste tires used in the production of recycled rubber, rubber powder, recycled rubber and rubber powder can be used to produce rubber products. A small amount of powder is directly used in asphalt modification, most of which is used to produce recycled rubber. For the conservation of raw rubber, reduce resource consumption, improve production costs, that have played a certain promoting role. At present, this has become the main way of waste tire recycling.
By the impact of national standard " Safety Specifications for Motor Vehicles Operating on Roads " (GB7258) and "be derelict of duty on three terms" (not repair, not change, not return goods) for the tires, tire refurbished enterprises nearly 70% in the cut-off or semi-shutdown state, and the number of tire refurbishment is expected to decrease by more than 50% compared with the same period of last year. Due to the impact of natural rubber prices and environmental protection, resulting in a significant reduction in the demand for recycled rubber. Recycled rubber production will decline by about 30% in 2014. Large-scale and regulated companies will be supported by the national government. Rubber powder production is about 350,000 tons, of which for the production of modified asphalt are 150,000 tons.
China is the world’s third largest tire producer, tire output is more than 130 million tires were produced in 2014, which were only less than America and Japan, in the same year there were 50 thousands waste tires generated. Therefore, the problem of recycling waste tires causing more and more attention from all walks of life, and relevant enterprises and inventors are bullish on the contained business opportunity.
Waste tires have been overstored for 300 millions in the world, and it remains increasing about 100 million per year, in which can be retreaded and utilized only account for 1.5％－2％. How to use waste tires effectively and antipollution is a difficult problem for all of the world. Our country can produce hundred millions tires, which is the third largest producer in the world. More than fifty thousand waste tires newly increased per year. As the number of cars climbed, so does the amount of waste tires. Waste tires are piled up like a mountain in some rural-urban areas.
China is expected to sell 340, 000 vehicles in 2022, and the auto market is the fourth largest in the world. Industry pundits predict that, by 2022, even in a shorter time, China will probably be the worlds largest car market. That means that the consumption of our car tires will also step in forefront among the world. At present, we produce more than 100 million tires per year, and the number of waste tires is about more than 50, 000.
The way people usually deal with solid waste is buried, burned, etc. But experts say these methods dont apply to waste tires, because waste tire is macromolecular stretchy material and is infusible, with high elasticity and toughness, which will not change within -5 ~ 15 ℃, and it will take hundreds of years to make their macromolecules break down to not affect the growth of the plants in soil. While if they are incinerated, the released smoke and carbon monoxide would seriously contaminate the atmosphere, and the severe pollution will make the surrounding area not even a blade of grass grows.
With the improvement of science and technology, people have ability to turn waste tires into a kind of renewable resources to recycle, and the value in use and application market is very big.
