In the era of the circular economy and the "dual-carbon" goals, the scrap tire recycling system centered on pyrolysis technology is transforming these troublesome tire wastes into valuable energy and industrial raw materials, creating a "tire circular economy" pathway from "black pollution" to "green closed-loop."
I. Pyrolysis Equipment: Technological Core and Industrial Foundation
There are four primary methods for recycling rubber (tires): tire retreading, production of reclaimed rubber, production of rubber powder, and pyrolysis. Among these, pyrolysis technology, as the ultimate method for scrap tire recycling, achieves harmless treatment, volume reduction, and resource recovery. Through pyrolysis reactions, scrap tires are converted into high-value-added energy products such as fuel oil, carbon black, and steel wire, with a comprehensive utilization rate exceeding 99%. This makes pyrolysis the most technologically advanced and highest-value-added solution in the scrap tire recycling system.
As a leader in the industry, Niutech has focused on the research and development of organic waste pyrolysis technology for over 30 years. Its self-developed industrial continuous scrap tire pyrolysis production line, which has been honored with the National Science and Technology Progress Award, achieves resource recovery, harmless treatment, and volume reduction of scrap tires under safe, environmentally compliant, and continuously stable operating conditions.
II. Building a Closed-Loop Industrial Chain for Scrap Tire Recycling
A complete tire recycling process encompasses the entire industrial chain, from raw material collection and pretreatment to pyrolysis reactions and deep processing of products.
The collection of scrap tires, the starting point of the entire industrial chain, requires aggregation at collection points before entering the plant due to the highly dispersed sources of generation. The scrap tires are first shredded into appropriately sized pieces by shredding equipment.
The pretreated rubber pieces are then fed into the tire pyrolysis equipment via a feeder, where pyrolysis reactions occur under oxygen-free conditions at specific temperatures. The rubber and fibrous materials in the tires undergo thermal decomposition, generating oil, carbon black, and a small amount of combustible gas.
The oil-gas mixture produced during pyrolysis is rapidly cooled through a cooling system, condensing the oil and gas at different temperatures into liquid oil in stages. The solid carbon black is discharged through the residue outlet and further processed into raw materials for rubber products, pigments, or fillers, which are then reintroduced into the tire production process. The recovered steel wire can be used in steel smelting and other industries.
The combustible gas and light hydrocarbon gases generated during the pyrolysis process are recycled and used as fuel for the pyrolysis equipment, improving energy efficiency and achieving energy savings and emission reduction.
III. Niutech's Germany Project: A Global Benchmark for Chinese Intelligent Manufacturing
Niutech has sold its equipment to numerous countries and regions, including Germany, Denmark, Brazil, Hungary, Turkey, Estonia, India, Thailand, Malaysia, and Iraq. Among these, the successful delivery of the Germany project marks that Niutech's equipment has met the stringent European Union requirements in terms of environmental protection and technical performance.
As a benchmark project for Niutech in the European market, the German project fully demonstrates the technical strength of China's high-end pyrolysis equipment. The project employs Niutech's self-developed industrial continuous scrap tire pyrolysis production line, efficiently and environmentally converting scrap tires into high-value-added products such as recovered oil, carbon black, and steel wire. The successful one-time delivery and stable operation of the German project not only validated the maturity and reliability of Niutech's technology but also opened the door for Chinese environmental equipment to enter the European high-end market.
The scrap tire recycling industry is positioned at the intersection of policy support and market demand. As environmental regulations become increasingly stringent and the global carbon economy develops, pyrolysis technology is becoming the most popular technological pathway for comprehensive scrap tire utilization. Compared with traditional methods, processing scrap tires through this technology achieves a carbon reduction of 1.1 tons per ton, delivering significant environmental benefits. At the same time, market demand for high-value-added products such as recovered carbon black and pyrolysis oil continues to grow, providing a solid economic foundation for industrial development.
From "black pollution" to "green closed-loop," guided by the "dual-carbon" goals, the scrap tire recycling industry will continue to unleash greater environmental and economic benefits on a global scale, making an indispensable contribution to building a green, low-carbon, circular economic system.
