At a waste tire pyrolysis plant in Turkey, Niutech’s industrial continuous waste tire pyrolysis project steadily produces oil and carbon black, with the recovered carbon black possessing high added value and recyclability, transforming tires from an environmental burden into urban minerals. Similarly, in developed countries such as Germany, Hungary, and Denmark, Chinese-manufactured tire pyrolysis technology and equipment operate reliably, offering Chinese solutions to address local “black pollution” challenges.
As a pioneer and leader in this field, the Chinese enterprise Niutech has dedicated over three decades to technological development, becoming the first STAR Market-listed company in China with pyrolysis as its core business and leading the formulation of multiple industry standards.
Leveraging more than 100 proprietary patents—including coking-free technology, gas-tight sealing, and anti-polymerization innovations—Niutech has achieved large-scale, long-duration, and stable continuous operation of its equipment, earning international recognition for its technical expertise. In 2024, its “Key Technology and Equipment for Industrial Continuous Waste Tire Pyrolysis and Resource Recovery” won the International Excellence Award in the Green Industry track at the BRICS Industrial Innovation Competition.
Niutech’s technology has gone global, with multiple projects implemented in BRICS nations such as Brazil and India, converting waste tires into high-value products like recovered carbon black and recycled oil, thereby turning “black pollution” into “urban minerals.” Its equipment has also successfully entered markets in developed countries, including the United Kingdom, Denmark, and South Korea, achieving worldwide promotion and application of continuous tire pyrolysis systems. Domestically, Niutech has established a 200,000-ton annual capacity comprehensive waste tire utilization project, which it independently operates. Certified by ISCC, the project exports pyrolysis products to developed countries, setting a benchmark in the waste tire recycling industry.
Tire pyrolysis oil, with its high calorific value, offers versatile applications and significant resource value. It can be directly used as fuel to provide thermal energy, replacing traditional fossil fuels, or serve as a chemical feedstock for further processing into other value-added products, generating substantial economic returns. Additionally, steel wires are remelted for reuse, carbon black is deep-processed for applications in tires and rubber sectors, and combustible gas is recycled as in-plant fuel, truly realizing a “from-tires-back-to-tires” circular model. Amid the global green transition, pyrolysis technology has become a vital pathway for the resource utilization of waste tires.
With the advancement of the global circular economy and carbon neutrality goals, pyrolysis technology is encountering significant opportunities. Strengthening industry standards, promoting the application of continuous environmental equipment, and leveraging policy guidance and demonstration projects to drive pyrolysis technology toward high-quality and sustainable development are crucial measures for the growth of the circular economy.
As the technology matures further and policy support intensifies, pyrolysis will play an increasingly important role worldwide. The path to green recycling of waste tires is broadening—from conceptual “circular utilization” to commercially scaled production.
