Addressing the challenges of End-of-Life Tires (ELTs) through high-throughput thermochemical recycling infrastructure.
The global disposal of scrap tires has become an environmental crisis, with billions of tires discarded annually. Landfilling and low-tech incineration cause severe pollution and resource waste. Modern waste-to-energy frameworks treat scrap tires not as waste, but as highly valuable feedstock rich in hydrocarbons.
For global waste management enterprises, oil conglomerates, and circular economy developers, securing high-yield tire processing machines is crucial for profitability. Standard shredding and mechanical granulating processes are energy-intensive and only downgrade the material. In contrast, Huayuan Tech's advanced continuous tire pyrolysis systems chemically breakdown rubber polymers into high-value commodities: Pyrolysis Oil (Tires Derived Fuel / TDF), Recovered Carbon Black (rCB), combustible Syngas, and steel wire.
Convert scrap tires into industrial heating fuel oil, combustible gas, and carbon black with low running costs, yielding positive financial returns within short payback periods.
Equipped with multi-stage exhaust scrubbing, desulfurization, and particulate filters to meet strict European Union (EU) and US EPA air quality standards.
Continuous feeding and hot-discharging designs allow up to 30 days of uninterrupted operation, drastically improving yield compared to batch processing.
Integrated Siemens PLC monitoring platforms enable full automation of heat, pressure, and material flow, reducing manual labor risks and overheads.
A history of pioneering breakthroughs in combustion engineering and polymer cracking technology.
Huayuan Tech launched basic thermal boiler engineering inside localized workshops, building foundations in thermodynamics.
Restructured under government industrial planning as Linyi Boiler Manufacturing Factory, initiating standardized vessel production.
Merged with Linyi Auto Parts Factory, establishing operations at Tongda Road and expanding manufacturing facilities.
Restructured into a joint-stock company, optimizing manufacturing efficiency and design departments.
Established a modern enterprise management structure, significantly upgrading quality control systems.
Obtained national A-level boiler license. Began designing our first generation of batch model waste tire pyrolysis systems.
Moved to Zaoyuan Town Industrial Park (220 acres). Pioneered automated R&D for continuous pyrolysis technology.
Successfully developed screw-running continuous pyrolysis plants. Secured ASME certification, expanding global exports.
Committed to deep emissions reduction and green systems integration, optimizing energy loops for eco-friendly performance.
Our continuous tire processing machines utilize a high-capacity horizontal rotating reactor design. The unit uses a heat-resistant, anti-coking screw feeder that processes rubber crumb or 5-10cm tire blocks continuously without letting oxygen enter the reactor chamber.
By integrating custom waste heat boilers and thermal integration circuits, the exhaust heat from the reactor is recycled back to preheat feedstock or generate steam. This decreases external fuel consumption by 30% to 40% compared to conventional processes.
Safety and Control Highlights:
Dual gas seals, automatic high-pressure release valves, water-sealed flame arrestors, and real-time infrared temperature tracking across multiple heating zones prevent combustible gas buildup.
Our pressure vessel testing equipment and quality control processes conform to international standards.
Because pyrolysis reactors operate under high temperatures and pressure, equipment reliability is vital. Poorly engineered reactors are prone to structural deformation, gas leakage, and crack fatigue. Huayuan Tech utilizes structural steel materials (such as Q345R boiler-grade steel) and automated welding equipment to manufacture every reactor shell.
Every weld undergoes non-destructive ultrasonic testing, radiographic testing, and hydrostatic pressure testing to guarantee 100% leak-proof operations. Our compliance with international codes like ASME ensures long service lifespans exceeding 8 to 10 years.
Comprehensive thermal conversion configurations tailored to global plant scales and regulatory specifications.
Pre-processing units designed to strip bead wire and shred whole tires into 5-10cm blocks for continuous reactor feeding.
Patented multi-stage airlock valves with nitrogen purging to prevent oxygen entry, ensuring complete explosion safety.
Optimized thermal insulation jackets utilizing gas burner arrays for even heat distribution, reducing energy loss.
Industrial-grade cooling towers and heat exchangers with large cooling areas to maximize oil recovery percentages.
Secondary micro-grinding and pelletizing systems that upgrade crude pyrolysis carbon black into commercial-grade filler.
Fractional distillation columns to refine heavy pyrolysis oil into higher-value diesel substitutes or heating oil.
Dedicated waste heat boilers capture flue gas thermal energy, converting it to steam for adjacent plant operations.
Activated carbon adsorption, desulfurization spray towers, and bag filters that yield clean, emission-compliant discharge.
From soil analysis and civil works design to installation, testing, and operation training, Huayuan Tech offers comprehensive global deployment support.
