Every year, 1.5 billion tires reach the end of their useful life worldwide. These “black mountains” don’t just take up space — they pose a serious, long-term threat. Left to degrade naturally, tires can take centuries to break down, while illegal dumping and open burning release toxic, cancer-causing pollutants that spread across continents via atmospheric currents. Secondary environmental disasters, from tire fires to mosquito breeding grounds, further compound the harm to ecosystems and human communities alike.

But what if those tires weren’t waste at all? Through tire pyrolysis, this so-called “black garbage” becomes a treasure trove of high-value resources. Modified pyrolytic carbon black can fully replace commercial carbon black; pyrolysis oil can be refined into industrial fuel oil and finished petroleum products; and the steel wire embedded in tires can be directly recycled for smelting. It’s resource recovery in action.

For over three decades, Niutech has been at the forefront of this transformation. As a STAR Market-listed enterprise (Stock Code: 688309) and national high-tech company integrating R&D, equipment manufacturing, and product sales, Niutech brings unmatched project experience and technical advantages to the tire recycling business. Niutech’s mature, stable, continuous scrap tire pyrolysis technology and integrated turnkey solutions have earned China’s highest science and technology honor — the National Science and Technology Progress Award — and been selected into the Major Environmental Technology Equipment Catalog jointly promoted by the Ministry of Industry and Information Technology and the Ministry of Science and Technology. Core technology has been identified as internationally advanced by authoritative institutions, and the equipment and technology have passed multiple international authoritative certifications, including EU CE, Germany TUV, ATEX, and ISCC. Products and solutions are sold to dozens of countries and regions worldwide, and Niutech has built the world’s leading continuous scrap tire pyrolysis demonstration base.

Niutech’s industrial continuous scrap tire pyrolysis complete set of equipment achieves harmless pyrolysis in an oxygen-free, closed environment, efficiently converting scrap tires into high-value products such as renewable pyrolysis oil, recovered steel wire, functional carbon black, and combustible non-condensable gas. The tire pyrolysis process of the entire system is scientifically designed and mature, ensuring conversion efficiency and product quality. The entire system adopts a fully closed-loop production mode, with 24-hour uninterrupted continuous feeding, pyrolysis, and discharging, and has core advantages such as large processing scale, high conversion efficiency, excellent environmental indicators, and outstanding economic benefits. Equipped with a self-developed exclusive flue gas purification system, tailpipe emissions fully meet global stringent regulations, outperforming international environmental standards such as the U.S. EPA and the EU EEA, truly achieving clean, harmless, and large-scale disposal. This makes sustainable tire recycling no longer a challenge.

Beyond ecological value, the scrap tire pyrolysis industry has extremely strong commercial viability and profit potential. According to industry public calculation data, per ton of scrap tire standardized pyrolysis treatment produces approximately 450 kg of renewable oil, 350 kg of modified carbon black, and 120 kg of recovered steel wire, and the comprehensive utilization added value is far higher than traditional renewable resource categories such as waste paper and waste plastic, and the profit level is superior to most traditional manufacturing industries. Market reference values: pyrolysis renewable oil 3,800–4,000 RMB/ton, recovered steel wire 1,500–1,800 RMB/ton, industrial carbon black 700–800 RMB/ton. According to authoritative calculations, every 100,000 tons of scrap tire disposal can achieve approximately 290,000 tons of carbon emission reduction, and the ecological carbon reduction value is significant. This also makes the tire recycling business a highly promising investment direction. With tightening global environmental policies, advancement of dual-carbon strategies, and increasing resource scarcity, the scrap tire resource recovery pyrolysis track has become a core trend in the solid waste recycling sector. In the future, Niutech will continue to deepen technological innovation, iterate and upgrade pyrolysis equipment and high-value application solutions, continuously empower the solid waste green recycling industry, balance ecological, social, and economic benefits, and continuously empower global green and low-carbon development.
