Pyrolysis Technology of Waste Rubber: Efficient Recycling from Tires to Oil and Niutech's Global Contributions

Approximately 1.5 billion waste tires are generated globally each year. Their non-biodegradable nature and challenges in recycling have led to severe "black pollution". Waste rubber pyrolysis technology, which converts discarded tires into high-value products such as fuel oil, carbon black, and steel wire through high-temperature decomposition, has become a critical solution for resource recycling and environmental protection. As a global leader in this field, Jinan Niutech Environment Technology Co., Ltd. (Niutech) has driven the transformation of the global waste tire recycling industry with its industrial continuous pyrolysis technology.

Waste Rubber Pyrolysis: The "Tire-to-Oil" Process
Waste rubber pyrolysis involves decomposing organic materials in an oxygen-free or low-oxygen environment at temperatures ranging from 400°C to 500°C, a process often termed "tire-to-oil". This technology enables thorough, harmless treatment and resource utilization of waste tires—the root cause of "black pollution"—ensuring they are fully repurposed with zero waste.

Niutech’s Industrial Continuous Pyrolysis Line
As a global benchmark in the industry, Niutech’s self-developed continuous waste tire pyrolysis production line employs "low-temperature pyrolysis" technology. Equipped with a PLC intelligent control system, the fully automated process achieves a pyrolysis rate of 99.5% while reducing energy consumption by 30%. This innovation overcomes the drawbacks of traditional batch equipment, such as high energy use, coking risks, and secondary pollution, delivering efficient, stable, and eco-friendly industrial operations.

Niutech’s Global Contributions and Technological Advantages
With 40 years of expertise, Niutech has advanced waste tire recycling from laboratory research to large-scale industrial applications, setting global technical benchmarks:

1. Technological Breakthroughs:

Its continuous production line offers broad material adaptability, low processing costs, and high product quality.

Recognized with China’s National Science and Technology Progress Award and EU ISCC Certification, the technology has been exported to over 20 countries, including Germany and Turkey.

2. Environmental Protection:

Eliminates risks of fires and soil contamination caused by open tire stockpiles.

Full compliance with EU emission standards, ensuring zero VOCs, no dust leakage, and no secondary pollution.

3. Economic Value:

Pyrolysis products—fuel oil, carbon black, and steel wire—hold significant market value. For example, fuel oil serves as a versatile raw material for chemical feedstocks or direct fuel sales, generating rapid economic returns.

Global Project Validation

• Germany Project:
  Niutech’s fully automated pyrolysis system operates 24/7, producing pyrolysis oil that is refined into high-performance chemical products while reducing carbon emissions.
• Brazil Project:
  A project in Brazil utilizes Niutech’s technology to recycle carbon black into high-value applications, transforming "black pollution" into "urban minerals" and boosting local resource recovery rates.

Niutech’s global project network spans dozens of countries and regions, including Germany, the UK, the U.S., Denmark, South Korea, Brazil, India, Turkey, and Vietnam. Its equipment, characterized by efficiency, low-carbon operations, and intelligence, addresses global organic waste challenges while driving the growth of circular economies.

Future Outlook
Through technological innovation and global expansion, Niutech provides a "Chinese solution" for circular economies and stands as a global environmental technology leader. As pyrolysis technology evolves and gains policy support, it is poised to become the mainstream path for solid waste recycling, extending its applications to broader fields and accelerating humanity’s transition toward a "zero-waste" society.
