According to statistics, in 2019, China’s waste tires generated about 330 million, equivalent to a weight of more than 10 million tons, and the amount of waste tires generated by scrapping every year is still growing at a rate of 6% to 8%.
Led by the circular economy policy, in recent years, China’s comprehensive utilization of waste tires industry has developed rapidly, the recycling rate of waste tires has increased year by year. 2019, the comprehensive utilization of about 1,500 enterprises, resource recycling of waste tires about 200 million, the recycling rate of about 60%. Among them, the volume of tire retreading is about 5 million standard equivalent bars, the production of recycled rubber is about 3 million tons, the production of rubber powder is about 1 million tons, and the volume of thermal cracking treatment is about 1 million tons.
Lack of mandatory retreading standards, tire retreading rate is relatively low
From the current form of reuse, recycled rubber and rubber powder is the main force in the treatment of waste tires, accounting for more than 50% of the total annual processing volume, continuous and automated thermal cracking accounted for a relatively low, while the tire retreading rate of only 5%.
In fact, tire retreading is the preferred way to recycle tire resources. With the original tire 35% of the raw materials, about 40% of the energy consumption and 50% of the price, you can retread a tire, and can run mileage can reach more than 90% of the new tire.
Superior performance, cost-effective, why China’s tire retreading rate is low? At present, the lack of mandatory retreading standards for domestic tires, the existence of heavy vehicles “a drive to waste” situation, tire wear to the end of the consideration of new tires, which makes the replacement of the tire carcass can not meet the retreading requirements.
On the other hand, people’s concept of tire retreading also needs to be changed. At present, the use of retreaded tires in the field of passenger cars in China is almost zero. Industry analysis, now many passenger car owners still have doubts about the quality of retreaded tires, most choose to simply repair or replace the tires after damage, which also leads to such waste tires can not be reasonably used.
Industry development prospect is broad
As a strategic new industry, despite the problems to be solved, but the survey, the interviewed enterprises generally optimistic about the market prospects of the comprehensive utilization of waste tires industry. In fact, along with the national environmental protection policies continue to increase and industry order to continue to regulate, waste tires are from the past “black pollution” into “black gold”.
A tire recycling plant annual processing of waste tires 60,000 tons, can get 24,000 tons of cracking oil, 22,000 tons of carbon black, 0.72 million tons of steel wire and a small amount of gas, the annual sales of these products is expected to reach about 80 million yuan. Thus calculated, if the country’s annual production of ten million tons of waste tires standardized processing, or can form an annual output value of more than ten billion yuan of industrial chain.
China’s car ownership is large and continues to grow, for the scrap tire market provides a sufficient market base. In addition to the strong demand, there is policy support. Previously, the National Development and Reform Commission issued a guide directory, clearly identified the comprehensive utilization of waste tires as a strategic new industry, making it a sunrise industry for the benefit of the country and the people.
The general tone of the future development of the industry is to ecological environmental protection as the foundation, to achieve circular development as the driving force, to energy saving and emission reduction as the path, to obtain renewable resources as the goal, and actively explore the Chinese program suitable for China’s national conditions, the development of the world tire recycling business can learn from, and contribute to human ecological environmental protection.
