On the morning of the 19th, China-Chengdu? Tire Resources Recycling Industry Large-scale Trade Fair was held in Chengdu Shuangliu. The reporter learned at the meeting that the comprehensive utilization level of used tires in China is low, resulting in huge waste of resources. Experts believe that in the reality of China's annual oil imports of nearly 280 million tons, the use of used tires is urgently required to establish relevant standards and strict supervision to regulate and promote.
As a more developed area of ​​China's tire repair and recycling industry, Sichuan has become the province of the western development engine. In 2010 and 2011, Sichuan Tire Renovation and Utilization Association successfully held two sessions of China Western Tire Resource Recycling Development Forum and Commodity Fair. The “Sichuan Modelâ€, which was nurtured in the western development for more than a decade, has a strong demonstration effect in the tire retreading and recycling industry.
According to the experts, the current domestic treatment of waste tires is mainly used for refining. Waste tires cannot be used or refurbished. They are mainly used to produce recycled rubber, rubber powder and pyrolysis oil. Old tires are tires that have been used but have a tread that has not yet reached the end of wear. They can be completely refurbished or partially refurbished.
"According to domestic and international experience, using qualified retreaded tires produced by regular enterprises is no different from new tires. The probability of puncture is lower than that of new tires." Experts at the meeting said that however, the utilization level of used tires in China is relatively low, especially the old ones. Tire retreading rate is low. “In the case of the old tire retreading rate of passenger and cargo trucks, the EU has reached 100%, the United States is 95%, and China is only 15%.†European and American countries stipulate that new tires must be refurbished, and some can reach three refurbishment standards. And the tires produced in China can be refurbished very little, almost the same as "disposable chopsticks".
Why is there such a gap? Zhu Jun, president of the China Tire Renovation and Recycling Association, believes that China lacks mandatory technical quality standards for the renewability of new tires. In order to save costs, some tire companies do not consider the tire retreading problem in the design, resulting in tire wear and poor overall strength. At the same time, there is no mandatory wear limit detection requirement for the use of tires in China, and consumers also lack the awareness of tire maintenance, resulting in less than 5% of “reversible tiresâ€.
Moreover, the poor quality of some tire retreading companies has seriously affected the reputation of retreaded tires. Sun Yongli introduced that some small workshops and small enterprises produce "top tires" because the newly added rubber treads are simply glued with the original tire surface only with glue, or even simply put together, the tires run not only It will leak, puncture, and even burn on fire.
"This meeting will implement the Interim Measures for the Administration of the Announcement of the Access to Waste Tire Comprehensive Utilization Industry issued by the Ministry of Industry and Information Technology on April 2 this year, to explore the measures for enterprises to achieve compliance, and to correct the current bad situation in the industry from the source." Zhu Jun said. The conference also invited the Taiwan Rubber Industry Association to participate in the delegation to directly link the production and demand of enterprises across the Taiwan Straits.
