In recent years, China's auto industry has grown more and more. China has become the world's largest auto country, and its tire production ranks among the top in the world. However, with the continuous increase in the number of waste tires in China every year, as of today, according to the survey data, the annual output of waste tires in China has reached 15 million tons, but the recycling volume has remained at about 6.5 million tons, and the recycling rate is less than 50%.
1. Why is the number of waste tires increasing every year?
Waste tires are called "black pollution" because the disposal of waste tires is very difficult. The raw material rubber used to produce tires has the characteristics of wear resistance, aging resistance, waterproof and shock absorption, so waste tires will not degrade even for hundreds of years. Tires piled up for a long time will not only occupy a lot of land, but also be prone to fire and seriously affect the ecological environment. Over the years, problems caused by waste tires have emerged in an endless stream, which is a problem recognized by the world.
How to deal with waste tires? What makes waste tires from "black pollution" to "black gold"?
2. Disposal methods of waste tires
First, waste tires with less severe wear and tear will be resold.
Second, waste tires can be made into exquisite handicrafts
Third, because the main raw materials of waste tires are natural rubber and synthetic rubber, steel cord, cord fabric and carbon black, so after secondary deep processing of waste tires, steel wire, cord fabric, rubber powder and carbon can be obtained. black, fuel oil, etc.
3. What are the benefits of deep processing of waste tires?
After waste tires are processed, steel wire, carbon black and tire oil are finally obtained. Steel wires removed from tires can be sent to steelworks for recycling. After being processed again, carbon black can be used again to make tires, rubber products, etc. Tire oil is made of rubber that is dissolved at high temperature and then cooled, and then distilled to obtain fuel oil, which can then be processed into gasoline and used as fuel.
From this point of view, the recycling profit of waste tires is very high. At present, China is also paying more attention to this industry. The National Development and Reform Commission issued a guidance catalog, clearly identifying the comprehensive utilization of waste tires as a strategic emerging industry, making it a sunrise industry that benefits the country and the people.
And in order to promote the healthy and rapid development of the waste rubber recycling industry, the state successively issued the "Commercial Used Tire Selection Specification", "Waste Tire Recycling System Construction Specification" and "Waste Tire Recycling Management Specification" to establish a truly standardized waste rubber and waste tire The recycling industry system encourages waste rubber and waste tire enterprises to transform in a green direction.
