In the era of the circular economy and “dual-carbon” goals, mountains of once-troublesome waste tires are being redefined as untapped “urban mines.” This “black pollution,” through advanced tire recycling solutions and processing technologies, is now being fully utilized and transformed into valuable “black gold.” As an industry leader and a renowned pyrolysis equipment manufacturer, Niutech exemplifies how Chinese intelligent manufacturing offers efficient and green solutions to global environmental challenges.
Waste tires are far from worthless garbage—they are rich in recyclable resources. A single waste steel-belted tire can be decomposed into fuel oil, carbon black, steel wires, and combustible gas, representing substantial economic value. Pyrolysis technology is widely recognized as the ultimate and final pathway for waste tire recycling. Unlike outdated “primitive oil refining” or small-scale batch production, modern advanced continuous and intelligent pyrolysis technology offers multiple significant advantages, making it an effective method for fully utilizing waste tires.
A mature pyrolysis system can achieve nearly 100% comprehensive utilization of waste tires. The primary product, pyrolysis oil, can be used as industrial fuel oil or further refined into gasoline and diesel. Recovered carbon black, after deep processing, can partially replace commercial carbon black as a rubber reinforcing agent in industries such as tires, rubber products, and asphalt. The separated steel wires serve as raw materials for the metallurgical industry, while non-condensable gas is fully recycled as system fuel, enabling energy self-sufficiency.
In terms of environmental protection and harmless treatment, continuous pyrolysis technology represents a qualitative leap. Modern pyrolysis equipment employs fully enclosed, automated, and intelligent production, achieving “zero pollution, zero residue, zero emissions, and full utilization.” With industry-leading technology, Niutech’s equipment ensures a pyrolysis rate exceeding 99%, delivering an efficient and environmentally friendly process.
Technological maturity and industrial prospects hinge on stable, continuous operation—a recognized technical challenge in the pyrolysis industry. Hindered by bottlenecks such as “equipment coking, sealing difficulties during feeding/discharge, and product polymerization,” most systems fail to meet the demands of industrial continuous operation, often operating below designed capacity. Therefore, overcoming these technical barriers to achieve safe, environmentally compliant, efficient, and low-consumption industrial continuous production is the core determinant for the large-scale adoption of pyrolysis technology.
In the journey of pyrolysis technology from the laboratory to large-scale industrialization, Chinese enterprise Niutech has played a pivotal role. Through over 30 years of dedicated research and development, Niutech has successfully overcome the global challenge of continuous operation, advancing the industry from crude practices to intelligent, continuous modern industrial processes, encompassing the entire industrial chain from waste tire collection and processing to the high-value application of pyrolysis products.
Niutech’s core achievement lies in its self-developed tire pyrolysis system, which integrates multiple patented technologies such as thermal dispersion, gas-tight sealing, and anti-polymerization. This effectively addresses industry pain points and enables safe, environmentally compliant, large-scale continuous operation. This technology has been honored with the National Science and Technology Progress Award and is listed as a key encouraged environmental technology in China.
1. Breaking International Technical Barriers and Earning Global Market Trust:
Niutech’s technology and integrated equipment have obtained rigorous international certifications, including the EU CE, German TÜV, ATEX explosion-proof, and ISCC International Sustainability and Carbon Certification. This signifies that its products meet top international standards in safety, environmental compliance, quality, and carbon reduction contributions. The equipment has been successfully exported to dozens of countries and regions, including Germany, the UK, Denmark, Brazil, Hungary, and South Korea, making Niutech one of the few domestic pyrolysis equipment suppliers capable of meeting stringent overseas technical requirements.
2. Innovating the “Equipment + Operations” Business Model to Establish an Industry Benchmark:
To enhance operational stability and sustainability, Niutech is actively transitioning from a single equipment supplier to a comprehensive service provider offering “equipment + operations.” In 2024, through its controlling stake in Hesheng GreenTech, the company launched a waste tire comprehensive utilization project with an annual processing capacity of 200,000 tons, poised to become one of the largest tire collection, treatment, and utilization projects nationally and globally.
Represented by Niutech, Chinese enterprises have not only solved the global challenge of continuous pyrolysis industrialization through decades of technological breakthroughs but have also exported Chinese solutions to the global market with internationally certified mature equipment and the innovative “equipment + operations” model. These efforts are set to make even greater contributions to building a green, low-carbon, and circular economic system.
