The “black pollution” caused by scrap tires is becoming an increasingly severe challenge. Currently, hundreds of millions of scrap tires and rubber products are generated worldwide. If these non-biodegradable wastes are disposed of using traditional methods, they will not only occupy a large amount of land resources, but illegal incineration will also release strong carcinogens such as dioxins and polycyclic aromatic hydrocarbons. After spreading through atmospheric circulation, they will not only pollute soil and water sources, but also enter the human body through the respiratory system, inducing respiratory diseases and malignant tumors. To address this global problem, Niutech from China has pioneered a brand-new “waste-to-treasure” path with its independently innovated technical solutions.

Niutech has been deeply engaged in pyrolysis technology for more than 30 years. With its independently developed “large-scale industrial continuous intelligent tire pyrolysis technology and complete sets of equipment”, it has become an undisputed innovation leader in the field of scrap tire treatment. Its core breakthrough lies in the precise regulation of the pyrolysis system, which allows scrap tires to fully complete pyrolysis under constant temperature and atmosphere, converting into high-value-added products such as pyrolysis oil, carbon black, steel wire, and non-condensable combustible gas. Among them, pyrolysis oil can be used as fuel for industrial boilers and can be further refined into light fuel oil; carbon black can be reused in tire manufacturing after deep processing; steel wire can be recycled for smelting; and non-condensable combustible gas can provide fuel for the pyrolysis process, truly achieving a “thorough utilization” of resource recycling.

As a benchmark technology in the field of scrap tire treatment, Niutech’s strength stems from its ultimate pursuit in the field of tire pyrolysis equipment. The tire pyrolysis equipment independently designed by the company adopts fully enclosed production technology and is equipped with an intelligent control system. It has reached the international leading level in terms of operational stability, processing efficiency, and environmental protection indicators, and has won the highest award in China’s science and technology field – the National Science and Technology Progress Award. The core advantage of this set of equipment lies in achieving an industrial breakthrough in continuous tire pyrolysis. Traditional pyrolysis technologies are mostly intermittent, with small single processing capacity and prone to pollutant leakage. However, Niutech’s equipment can realize 24-hour continuous feeding, discharging, and pyrolysis. A single production line can process more than 50 tons of scrap tires per day, with an annual processing capacity exceeding 15,000 tons, and the processing capacity is more than 10 times that of traditional technologies.

As a world-leading pyrolysis equipment manufacturer, Niutech’s technical strength has been verified in dozens of projects at home and abroad. Domestically, scrap tire treatment projects have covered more than ten provinces and cities, such as Shandong, Zhejiang, and Guangdong. Internationally, it has successively become an important technical supplier to dozens of countries, including Germany, the United States, and South Korea.

Niutech’s innovation is not only reflected in the technical level but also reshapes the value chain of scrap tire treatment. Among its pyrolysis products, carbon black can be used in the production of new tires, steel wire can be processed into steel raw materials, and non-condensable combustible gas can realize “self-production and self-use” to provide clean energy for the production process, forming a closed-loop cycle of “waste – pyrolysis – recycled resources”. Looking forward to the future, Niutech is adhering to the concept of leading low-carbon circular development through technological innovation, accelerating its global layout. With 30 years of persistence and innovation, Niutech has proven that technological innovation is the key to achieving harmonious coexistence between humans and nature, and Chinese enterprises are contributing replicable advanced solutions to global sustainable development with leading technologies.
