Niutech: Continuous Tire Pyrolysis Technology Ushers in a New Era of Waste Rubber Recycling

In 2022, global waste tire production reached 39.238 million metric tons, with China accounting for 32.6% (12.8 million metric tons). However, over 60% of these tires are still disposed of through traditional landfill or incineration methods, leading to annual soil and water pollution from approximately 7 million metric tons of waste rubber. While mechanical crushing methods can produce rubber powder and reclaimed rubber, issues such as performance degradation and limited application scenarios persist, resulting in economic value that is only 15%-20% of the original tires. Niutech's innovative continuous tire pyrolysis technology converts waste tires into recycled oil, carbon black, and steel wire through high-temperature anaerobic decomposition, achieving a resource conversion rate of 98%. This breakthrough offers an efficient global solution for waste tire disposal.  

Advantages and Significance of Tire Pyrolysis Technology and Equipment  
1. Maximized Resource Utilization  
Pyrolysis technology decomposes waste tires in a high-temperature, oxygen-free environment into high-value products such as fuel oil (45-50%), carbon black (30-35%), steel wire (10-15%), and combustible gas (10%). This process achieves near-total resource extraction, particularly for passenger tires, which have low reclaimed rubber and rubber powder value. Pyrolysis thus serves as their ultimate treatment method, with resource utilization approaching 100%.  

2. Outstanding Environmental Benefits  
Compared to traditional landfill and incineration, pyrolysis technology eliminates black smoke and odors through advanced flue gas purification systems (e.g., desulfurization, dust removal), significantly reducing CO₂ and harmful gas emissions while complying with national environmental standards. It also mitigates long-term risks of tire stockpile-induced fires and soil contamination.  

3. Economic Viability  
Pyrolysis products like fuel oil and carbon black hold broad applications in the energy and rubber industries. For instance, pyrolysis oil (40 MJ/kg calorific value) can be blended with diesel, while carbon black serves as a reinforcing agent in rubber products, boasting substantial market potential. With all outputs being highly valuable, the technology delivers robust economic returns.  

Niutech, a Chinese cleantech leader, has independently developed continuous pyrolysis equipment that overcomes traditional challenges of low efficiency, high energy consumption, and incomplete processing. Capable of handling all categories of waste tires—from passenger to truck and engineering tires—this technology has emerged as the mainstream approach for tire recycling.  

Global Impact and Leadership  
Niutech has become an industry benchmark, establishing a 200,000-ton-scale tire recycling demonstration project in Shandong, China—the world's largest waste tire pyrolysis facility. Its equipment operates in dozens of countries, including Germany, Denmark, Hungary, Turkey, Estonia, South Korea, Brazil, India, Thailand, Malaysia, and Iraq. Running continuously 24/7, these systems transform waste tires into high-value products, resolving pollution challenges while generating wealth for owners.  

From Black Pollution to Green Resources  
Niutech's continuous pyrolysis technology demonstrates the feasibility of industrial waste upcycling. With pyrolysis oil now included in China's national strategic energy reserves and breakthroughs in carbon black modification, this "tire-to-oil" green pathway is reshaping the sustainable development landscape of the global rubber industry.
