The pollution problem caused by waste tyres has long been a key challenge in the global environmental protection field. This has also provided a stage for a new generation of environmental protection technologies, which can transform waste tyres from an “environmental burden” into recycled raw materials through advanced pyrolysis technology. In recent years, countries around the world have successively issued laws and regulations to promote the resource utilization of waste tyres. The EU’s Circular Economy Action Plan clearly requires that the waste tyre recovery rate reach 95% by 2030; countries such as Germany and France have positioned pyrolysis technology for waste tyre pyrolysis as a technical path for priority promotion. The United States Environmental Protection Agency (EPA) has recently revised the Resource Conservation and Recovery Act (RCRA), setting strict limits on VOC emissions from tyre disposal. Traditional methods such as landfilling and incineration are gradually withdrawing from the market due to their low resource utilization efficiency, and the industry’s demand for high-end pyrolysis equipment that is compliant and economically viable has become increasingly urgent.

At present, the waste tyre treatment industry faces three major challenges:

The high energy consumption and low efficiency of batch-type tyre pyrolysis equipment make it difficult to meet the demand for continuous disposal of 10,000-ton scale.

High-temperature cracking is prone to coking, and difficult dynamic sealing leads to severe secondary pollution.

The insufficient purity of pyrolysis products limits their high-value application.

High-end intelligent continuous pyrolysis equipment, which combines environmental compliance with economic efficiency, has become an important technical equipment option to drive innovation in tyre recycling, and meets the environmental protection needs of high-end markets in Europe and America.

Niutech is the standard-setter and technology leader of pyrolysis technology in China. The company has focused on pyrolysis technology for 30 years and has independently developed a high-end continuous pyrolysis production line. This production line solves the challenges of the waste tyre treatment industry with eight core technologies and has won the “National Science and Technology Progress Award”—China’s highest honor in environmental protection technology.

Through its patented designs for special mechanisms and heat energy recovery, Niutech’s high-end intelligent pyrolysis equipment ensures uniform heating of materials in the reactor, completely solving the shutdown problem caused by issues such as high-temperature coking. In global project practice, more than ten projects have been operating stably for over a decade, which has fully verified the reliability of this tyre pyrolysis equipment.

Efficient and compliant whole-process production is the key to meeting European and American standards. The production line adopts a fully enclosed process, with dust and VOCs emissions approaching zero, and the project test data fully complies with the strictest EU environmental protection requirements. The pyrolysis products produced are of high and stable quality. The PLC/DCS system enables real-time monitoring of nearly 10,000 parameters of the production line, with functions of automatic deviation correction, alarm, and disposal. After high-value processing of the pyrolysis products, the recycled carbon black produced can be further processed for use in the manufacturing of new tyres. Currently, this production line of Niutech has been fully applied in industrial projects across dozens of countries around the world, forming a complete closed loop of “technology R&D – project implementation – standard output”.

Amid the global wave of accelerating energy conservation, carbon reduction, and circular economy advancement, Niutech’s large-scale intelligent continuous tyre pyrolysis production line effectively solves the problems of environmental compliance in tyre pyrolysis and efficient resource utilization with high value. It helps global customers achieve green growth in both environmental protection and revenue, enabling the transformation of waste tyres from “black pollution” to “green resources”.
