Globally, over 1.5 billion scrap tires are generated each year. These rubber-based wastes are extremely difficult to degrade naturally and are widely known in the environmental sector as “black pollution.” Not only do they occupy vast amounts of land for extended periods, but they also pose serious fire hazards—spontaneously combusting under certain conditions and releasing toxic fumes and oily residues that severely threaten ecosystems and public health. Efficiently and cleanly converting these scrap tires into renewable green energy and high-value materials through tire-to-fuel recycling has become a critical focus for the global environmental industry.
Niutech is a world-leading innovator in continuous pyrolysis technology. For more than 30 years, the company has specialized in the R&D and industrialization of advanced, intelligent pyrolysis equipment. Niutech successfully scaled its continuous tire pyrolysis technology from lab-scale experiments to large-scale industrial deployment. Its self-developed “Large-Scale Industrial Continuous Intelligent Tire Pyrolysis Production Line” is built upon an award-winning proprietary technology system that received China’s highest scientific honor—the State Scientific and Technological Progress Award. This system establishes an innovative pathway to transform scrap tires into high-value products such as fuel oil, recovered carbon black, and syngas, offering a replicable and scalable “Chinese solution” for global scrap tire valorization.
Most scrap tire recycling equipment currently on the market still relies on outdated batch-processing systems. These units suffer from unstable operation, high energy consumption, low automation, and frequent issues like odor leakage, inadequate off-gas treatment, and inconsistent oil quality. Niutech has pioneered a comprehensive technological upgrade. Its production line features a fully enclosed, fully automated, and continuously feeding/discharging design, with a single line capable of processing 10,000 to 50,000 tons of scrap tires annually—marking a true shift toward industrial-scale, stable operations.
The integrated system combines intelligent temperature control, multi-stage flue gas purification, oil distillation and refining, carbon black activation, and energy recovery modules. This ensures the entire rubber pyrolysis process operates efficiently and cleanly—without open flames, dioxins, or wastewater discharge. The resulting pyrolysis oil can be used directly as industrial boiler fuel or further refined into light diesel, while the high-quality recovered carbon black finds wide application in new tires, rubber goods, coatings, and plastic fillers—enabling full resource circularity.
Beyond hardware advancement, Niutech’s continuous tire pyrolysis line represents a leap in digital intelligence. Its proprietary DCS intelligent control system monitors and automatically adjusts tens of thousands of real-time operational parameters—including temperature gradients, pressure distribution, gas composition, and material flow rates—dramatically reducing labor costs and operational risks while significantly enhancing system stability and product consistency.
As the circular economy gains global momentum, Niutech is turning the once-dreaded “black pollution” into a valuable “urban mine” through its internationally recognized industrial continuous scrap tire pyrolysis technology. This breakthrough isn’t just technical—it’s a transformative model for sustainable development. With growing adoption worldwide, Niutech is driving the tire recycling industry toward a future defined by green innovation, low carbon emissions, and high-value circularity—making meaningful contributions to a “zero-waste world” and a more sustainable planet.
