Amid the deepening global push for sustainable development, the circular economy has become the core path for resource efficiency and ecological protection. The recycling and disposal methods for waste tires have long been regarded as a key challenge in the circular economy field, and the problem of “black pollution” they cause urgently needs addressing. According to authoritative data from the International Rubber Research Organization, over 1.6 billion waste tires are produced worldwide each year, and this number continues to grow at an average rate of 5% annually. Traditional disposal methods, such as incineration, release carcinogenic substances like benzo(a)pyrene and polycyclic aromatic hydrocarbons, which spread globally through atmospheric circulation, posing serious threats to human health and ecosystems. Meanwhile, open-air storage of waste tires not only consumes vast land resources but also creates breeding grounds for mosquitoes and insects due to water accumulation, becoming a major health risk for diseases like dengue fever and malaria. This highlights the urgent need for new, sustainable modes of waste tire recycling.
In this challenging context, Niutech has revitalized waste tires through innovative continuous pyrolysis technology. As a global leader in waste tire pyrolysis, Niutech has dedicated over 30 years to industry development, investing heavily in R&D, and successfully overcoming numerous technological barriers. The company developed the “NIUTECH® Waste Tire Pyrolysis Technology.” Based on molecular bond-breaking and reassembly principles, this technology precisely controls pyrolysis temperature, pressure, and reaction time, enabling efficient separation of rubber, steel wire, and carbon black from waste tires and transforming them into high-value products like fuel oil, carbon black, and steel wire. This represents a significant leap from “black pollution” to “circular resources.” This pyrolysis project mode offers a new path for global circular economy development and provides a scientifically sound technical solution for waste tire recycling.
Niutech’s industrial continuous pyrolysis equipment has demonstrated strong technical advantages and market competitiveness worldwide. To date, the equipment has been successfully applied in dozens of waste tire pyrolysis projects globally. As a listed company on the STAR Market in China, Niutech has received the highest honor in China’s environmental protection field — the National Science and Technology Progress Award. Its core equipment adopts a fully enclosed, intelligent production process, controlled by PLC automation systems, capable of operating 24 hours continuously and stably. A single production line can process over 10,000 tons of waste tires annually, with a processing efficiency exceeding 40% compared to traditional equipment. The system is also equipped with advanced multi-stage flue gas purification and heat recovery systems, which deeply purify exhaust gases produced during pyrolysis, ensuring emissions far better than EU standards. Meanwhile, the recovered heat from pyrolysis is efficiently recycled for production processes, achieving energy circularity. This not only reflects Niutech’s innovation in tire recycling methods but also demonstrates significant environmental benefits, truly reaching the ideals of “zero pollution and full recycling.”
Looking ahead, as the global emphasis on environmental protection and resource recycling continues to grow, the waste tire pyrolysis industry is poised for broader development space. Niutech will continue to strengthen technological innovation, optimize pyrolysis technology and equipment performance, and actively expand applications in the organic solid waste sector, contributing more “Chinese wisdom” and “Chinese solutions” to global circular economy development and ecological protection. In future waste tire recycling endeavors, Niutech’s leading technology and innovative outlook are expected to improve tire recycling methods further, create greater environmental benefits, and lead the industry toward new heights.
