 Talking about the waste tire recycling value and meaning

l  Car scrap tires resulting in a "black pollution." How to deal with them? This has become a worldwide environmental problem.

l  With the need for waste tire recycling car becoming the first engine to pull domestic consumption, China is already facing a serious problem of environmental pollution caused by waste tires. According to incomplete statistics, China is the world's second-largest tire producer. With the national surge in demand for cars, scrap tires has gradually become a new solid waste pollution. To deal with waste piled up tires, burned, or you can choose a long-term open dumps. However, no matter whether burned or long-term open dumps, waste tires will take up a lot of land, but also easy to breed mosquito-borne disease, severe deterioration of the natural environment, the destruction of plant vegetation, seriously endangering the global environment. Moreover, the process can easily burned tires easily cause a fire threat to people's lives and property safety. Thus, stacking, landfill, solid waste treatment methods for waste tires burned, etc. do not apply. How to deal with the nascent "black pollution" solid waste has become a new era of social discussion and attention.  

 

Waste tire recycling value and meaning

l  Waste tire retreading - waste tire recycling economy reflects the new renovation, as the name suggests is to deal with waste tires and then after a certain market, and re-utilized, it is apparent the renovation and reuse of waste tires will play for the development of circular economy to a certain role. According to China's renewable resources online transaction data, once every renovation, new tires can regain the equivalent of 60% to 90% of the life of the life of the average mileage of about 5-7 kilometers through several renovation, at least make the tire total 1 to 2 times longer life, in other words, a tire after several refurbishment at least the equivalent of two to three tires. By accelerating the construction of a sound waste tire recycling network system market in order to change the waste tire recycling disorderly situation can largely contributed to the development of recycling waste tire retreading industry. Renovation is the main way to make use of scrap tires and the best choice. Since the renovation maintained the original tires and shape, energy consumption and labor are less, but its purpose the best use of it is generally considered the most effective use of the method of waste tires. In the United States, each year more than 60% of scrap tires were renovated; in Europe, more than 25% per year of waste tires were renovated; in China, although the domestic tire retreading technology

  

l  And renovation of speed and advanced Western countries there are obvious gaps, but the annual domestic tire retreading rate reached 10% or more. That is, the renovation of scrap tires in large part to solve the problem of waste tire piles, making scrap tires about 1/3 to get recycled. In addition, a waste tire retread materials consumed only a fairly new tires with the specifications of 15% to 30% of the production, which is a resource-saving society and environment-friendly society requires. In addition, after the renovation of the sales price of scrap tires only 20% to 50% of the new tire conforms to the fundamental interests of the broadest masses.

 

l  In pavement engineeringThe application shows that the development of the rubber asphalt, rubber asphalt road not only can improve the performance and extend the life of the road surface, and can reduce the black pollution, waste tires on the earth response is more effective solution.  

 

l  Solid waste fuel - the incarnation of light and heat waste tire material is a high calorific value per kilogram of wood heat than the high of 69%, higher than the bituminous coal 10% 4% higher than the coke. The waste tire broken, then a certain proportion of combustible waste materials with a variety of mixed formulated into solid waste fuel (RDF), for blast furnace injection instead of coal, oil and coke as fuel or cement instead of burning coal and thermal power generation. Meanwhile, the law as well as by-products - carbon generated by activated again as a reinforcing agent for rubber products. Today, in many States, Japan and European countries, many cement plants, power plants, paper mills, steel mills and smelters are using scrap tires as fuel, the effect is very good, not only reduces the cost of production, but also to cure the cause of scrap tires environmental problems.

 

l  The tire rubber and metal separation. Rubber and tire separated maintaining the original features and functions that can be used to produce tires again.

 

l  Thermal decomposition - the best fuel

The resulting thermal decomposition characteristics of the fuel oil and similar commercial, or may be used to extract the direct combustion of fuel mixed with oil, can also be used as a softener in rubber processing. The resulting thermal decomposition of the combustible gas mainly composed of hydrogen and methane can be used as fuel, the heating needs to be decomposed in situ combustion process. Thermal decomposition of the resulting carbon black toner can replace the use of, or after processing into special adsorbent. This adsorbent for water contaminants, especially mercury and other toxic metals have a strong filtration effect. Furthermore, there is a thermal decomposition product of steel wire.

 

l  By scrap tire retreading, prototype restructuring, rubber asphalt paving, solid waste fuel, recycled plastic and thermal decomposition, recycling scrap tires have gradually embarked on a new stage, a new stage of development. Through different waste tire recycling, not only to solve the shortage of resources, environmental degradation problems, and promote the development and the development of emerging technologies, and to protect people's lives and health of the whole society, the ultimate benefit of the people, for the benefit of society.
