In European and American countries, the disposal of scrap tires has long been a tough problem. The United States, as a country with an extremely high number of cars, has about 300 million vehicles, generating a large number of scrap tires every year, with a cumulative total of as many as 3 billion. Europe, the birthplace of the automobile industry, also produces a huge number of scrap tires annually. These scrap tires not only occupy a large area but are also extremely difficult to degrade. Once a fire breaks out, the consequences are unimaginable, causing huge environmental pollution and safety hazards.
Traditional scrap tire disposal methods, such as landfilling and incineration, have exposed many drawbacks in European and American countries. Landfilling requires a lot of valuable land resources, and tires are difficult to degrade naturally. They remain underground for a long time, posing potential pollution to soil and groundwater. Although incineration can reduce the volume to a certain extent, it releases a large amount of toxic and harmful gases, such as sulfides and nitrogen oxides, which seriously deteriorate air quality and do not meet the current strict environmental protection standards. At the same time, these traditional methods cannot realize the effective reuse of resources, which not only wastes a lot of recyclable resources but also requires high processing costs.
In recent years, more and more countries have turned their attention to tire pyrolysis technology, which stands out with many significant advantages. Tire pyrolysis technology is based on the thermal instability of organic matter. Under the conditions of oxygen-free or oxygen-poor environment and specific temperature, macromolecular organic matter is converted into gaseous, liquid, and solid components through decomposition and condensation. Its products include carbon black, steel wire, pyrolysis oil, etc. These products can be converted into high-value products after further processing, realizing the resource utilization of waste. This not only helps alleviate the problem of resource shortage but also brings considerable economic benefits to enterprises.
Among numerous pyrolysis technologies, the large-scale intelligent tire pyrolysis equipment from China’s Niutech performs particularly prominently and has successfully achieved commercial applications in dozens of countries such as the United States, the United Kingdom, South Korea, and Hungary. Niutech’s pyrolysis process has effectively solved three world problems under large disposal volumes: “easy coking of the pyrolysis system, difficulty in dynamic sealing of feeding and discharging, and easy polymerization of products”, and thus won China’s highest scientific and technological award – the National Science and Technology Progress Award. Its pyrolysis equipment features efficient processing, low energy consumption, and simple operation. By adopting advanced waste heat utilization technology and flue gas purification technology, the pyrolysis process can be completed quickly, and non-condensable combustible gas and high-temperature flue gas can be recycled to provide energy for pyrolysis. The waste heat utilization efficiency is as high as over 90%, greatly reducing fuel consumption. In addition, Niutech’s scrap tire pyrolysis process is equipped with an advanced PLC and DCS fully automatic intelligent control system, which can perform highly intelligent operations such as real-time monitoring, data collection, operation display, calculation, processing, and alarm for core components and key areas, ensuring the safe, efficient, stable, and high-quality operation of the entire system.
European and American countries choose tire pyrolysis technology precisely because of its comprehensive advantages in environmental protection, economy, and technology. By adopting this technology, the problems of environmental pollution and resource waste caused by scrap tires can be effectively solved, realizing the unity of economic, environmental, and social benefits. In the future, with the continuous progress of technology, high-end continuous pyrolysis processes represented by Niutech will play a greater role globally, promoting the field of scrap tire treatment to stride forward in the direction of sustainable development.
