At present, China is one of the world's largest auto press "reset" key fee markets, and the consumption of auto tires is also increasing day by day. How to deal with a large number of waste tires that will not lead to environmental pollution has become a serious practical problem. Recently, relevant researchers from the Jinhu tire (China) R & D center in Tianjin by South Korea's Jinhu Asiana group suggested that China's tire manufacturing industry can introduce but obviously still face many challenges at the current stage to solve this environmental problem by using the internationally mature waste tire treatment project - tire derived fuel (TDF) waste tire recycling, heat sealing and power generation project. The project requires the Chinese government to formulate some laws on energy supply law and relevant environmental laws on the use of waste tires as fuel to make the measured data more complete. It is reported that developed countries have already formulated relevant laws to reuse resources and protect the environment
the high calorific value of waste tires makes them a good alternative fuel for energy intensive industries such as cement plants, power plants, pulp mills and paper mills. According to the U.S. Environmental Protection Agency, tires produce as much energy when burning as oil, more than coal. These metal surfaces can form a fine oxide film of 25% - 50%, and 100% - 200% more than wood. Waste tires have been used as supplementary fuel for coal and wood. Over the years, more and more combustion plants have used waste tires, not only because of their high energy content, but also because they are cheaper than coal, produce cleaner emissions, and have low moisture content. According to the test, the ash residue of tires contains less heavy metals than some coals, and the nitrogen oxides emitted by tire combustion are less than those emitted by high sulfur coals
75% of each waste tire can be used for power generation in this project, and the rubber powder and steel in the remaining raw materials can also be recycled. It is reported that Jinhu petrochemical, a subsidiary of Jinhu Asiana group, has invested nearly US $500million to develop a power generation project using waste tires, which has begun to enter the stage of commercial operation. One production line of the project can process 14million waste tires every year, and the power generation generated by 90000 tons of TDF fuel is equivalent to burning 200000 tons of coal. Through this project, a large number of waste tires can no longer be discarded in nature to pollute the environment, so as to achieve renewable utilization, while generating clean renewable energy and protecting the environment
