"Black pollution" can become "green wealth"

With the development of the automobile industry, more and more "black pollution" formed by used tires is threatening us. According to statistics, China is the third largest tire producer in the world. In 2001, the tire production exceeded 130 million, second only to the United States and Japan. At that time, 50 million waste tires were produced in the suburbs of Beijing and Shanghai. Places can see piles of waste tires that stretch for more than a kilometre like a hill. Moreover, with the vigorous development of China's auto industry, the generation of used tires will increase dramatically. If this “black pollution” is not handled early, it will cause great harm to the environment. Therefore, the issue of recycling of used tires has attracted more and more attention from all walks of life, and the business opportunities contained therein have also been viewed by related companies and investors.
Used tires can become a 'renewable resource'
People usually deal with solid waste by landfill, burning, etc., but experts believe that these methods are not applicable to used tires. This is because discarded tires have high elasticity and toughness and do not change in the range of -50°C to 150°C. The decomposition of their macromolecules to a level that does not affect the growth of plants in the soil requires hundreds of years. If it is burned, the smoke and carbon monoxide released from it will seriously pollute the atmosphere.
However, the existence of a large number of used tires, like time bombs, endanger humans at any time. This is because the used tires are flammable, and the fire spreads very quickly during fires, saves a long time, and consumes a large amount of police force. At the same time, the smoke generated by combustion causes serious air pollution. If a fire occurred at a used tire recycling station in Nan'an District, Chongqing City on February 24 last year, the fire brigade dispatched 19 squadrons of eight squadrons and fought for 1 hour and 20 minutes before they were extinguished. The huge black smoke generated by the tire burning shrouded the area of ​​1,000 square meters. In addition, waste tires that accumulate more and more are piled up in the open air for a long period of time. It does not matter if they occupy a large amount of land, and they can easily breed mosquito-borne diseases. According to experts from the Beijing Municipal Bureau of Industrial Hazardous Waste Management, used tires not only deteriorate the natural environment, but also destroy vegetation, affect human health, and endanger the ecological environment of the earth. They are one of the most hazardous wastes in industrial hazardous waste.
In fact, with the advancement of science and technology, people have the ability to turn waste tires into a renewable resource for recycling, and the use value and application market are very large. According to experts such as Deng Haiyan, a senior engineer of the China Rubber Group's Shuguang Rubber Industry Research and Design Institute, at present, there are many technological achievements in the world that use waste tires as resources for recycling, such as prototype restructuring, thermal energy utilization, thermal decomposition, and tires. Refurbishment and production of reclaimed rubber or powder.
According to the incomplete statistics on the industrial opportunities for the recycling of waste tires, in 2001, there were more than 50 million waste tires produced in China, of which more than 20 million were unattracted, and the recycling rate was less than 60%, which is 90% of that of developed countries in the world. The proportions are far from each other. In spite of this, it is not difficult to find out from the above analysis the huge market space and profit space that the waste tire recycling industry has. So where are the market opportunities?
China is a country that consumes large amounts of rubber resources, and at the same time, it is a country with very scarce rubber resources. According to this national situation, the connotation of China’s waste tire recycling industry mainly includes three areas: tire retreading, reclaimed rubber and rubber powder, and thermal energy utilization and Thermal decomposition is not the best choice for China.
Tyre: The lack of fetal sources hinders its development. There are about 500 old tire retreading companies in China. In 2001, more than 4 million old tires were refurbished. A total of 200,000 tons of used tires were disposed of. The ratio of new tires to retreaded tires was 26:1. , well below the world average of 10:1 or 9:1. According to the world average, 10 million old tires in China each year should be refurbished without refurbishment, and lost more than 2 billion yuan in profits in vain.
Why did China's retreading industry fail to complete the market? On the one hand, it is technology, although Zhu Jinlin, Chairman of Fujian Xianfeng Rubber Products Company, pats his chest to the press and experts, saying “Dare to challenge with Michelin, and the technology has definitely reached the world’s advanced level”, and experts have introduced the giant 3600R51 produced by Michelin. The engineering tires used in mines have a service life of 2,600 hours, while the retreaded tires of the same specifications produced by Chinese companies in the Jiangxi Dexing Copper Mine have a life expectancy of 1900 hours, which is equivalent to 70% of the life of new tires. However, technology is a bottleneck after all.
And what is even more crucial is the lack of births. According to Li Gang, deputy director of the General Office of the Ministry of Communications of the People's Republic of China, and Jiang Zhiyun, president of the China Tire Renovation and Utilization Association, the lack of fetal sources stems from the fact that people know too little about the value of tire refurbishment, so that wear is not considered during tire use. Ultimately, one tire often runs to the end; on the other hand, because the car is heavily overloaded, the carcass is destroyed.
Reclaimed rubber: Market prospects are optimistic in the next 5 to 10 years. China is the world's largest producer of reclaimed rubber. There are more than 600 reclaimed rubber companies with an annual output of 350,000 tons of reclaimed rubber, and a total of about 500,000 tons of used tires are disposed of. More than 60% of the tires are recycled. These enterprises are the main force of the waste tire recycling industry in China.
Why is the reclaimed rubber industry in the sunset industry in the developed countries still leading the way in China? Zhang Yanbin, general manager of Jiangxi Guoyan Rubber Co., Ltd., Cao Qingxin, general manager of Nanjing Xieli Rubber and Plastic Co., Ltd., and Ni Xuewen, chairman and general manager of Nantong Backbone Rubber Group Co., Ltd., believe that it is mainly related to the production of biased tires in China. In recent years, Chinese tire companies have been mainly producing biased tires. Even in 2005, the output of biased tires and the radial tires each accounted for half. This determines that the reclaimed rubber industry, which uses waste tires as its main raw material, will continue to develop well in the next 5 to 10 years. In recent years, many reclaimed rubber enterprises in China have undergone technological transformation, basically achieving pollution-free, pollution-free production, and are moving in the direction of the 'green environmental protection industry'.
However, the reclaimed rubber industry is also facing an embarrassing situation. Because developed countries such as the United States have gradually eliminated the reclaimed rubber industry, domestic public opinion has always opposed the development of the reclaimed rubber industry.
Powder: The technical hard market is weak We are optimistic that the rubber powder industry has not received due development in the past two years. There are nearly 40 rubber powder enterprises in China, but the annual production of rubber powder is less than 50,000 tons, and a total of used tires are disposed of. About 100,000 tons.
The status quo in China's rubber powder industry is hard technology and weak markets. At present, China's self-developed normal temperature production of plastic powder technology has reached the world's leading level. In July last year, a new waste tyre processing and production line designed and manufactured by Dalian Sanhe Environmental Protection Equipment Co., Ltd. successfully implemented the treatment of steel radial tires, which enabled them to peel off the steel wires and fibers in the radial tires, and took over the world at one stroke. The last and most difficult hurdle in the field of waste tire milling. However, the market for the application of rubber powder has not yet been effectively developed. The reason is that the downturn of the tire companies caused the arrears in the payment of goods in the industry to be very serious, making the circulation of liquid capital in rubber powder companies unsatisfactory. Although the application range of rubber powder is very wide, due to the separation between the industry and the industry, many new products like rubber powder waterproof coating, rubber powder modified asphalt, etc. are difficult to be applied in building materials fields or transportation departments. .
