Tire Pyrolysis in a Rotary Kiln: How Waste Tires Become Oil, Steel and Carbon
Tire Pyrolysis Rotary Kiln
Waste tires are a concentrated tangle of rubber, steel and carbon, and for decades the main options were burning or burying them. A rotary kiln offers a third path: heating shredded tires in an oxygen-free atmosphere until the rubber thermally cracks into oil vapour and gas, leaving the steel and a carbon-rich char behind, all in one continuous process.
How Tire Pyrolysis Works in a Kiln
Shredded tire chips are fed into a slowly rotating, indirect-fired kiln, where they are heated to roughly 400 °C to 550 °C in the absence of oxygen. The volatile hydrocarbons boil off as vapour, which is condensed into tyre-derived oil, while the non-condensable gas is recycled to help fuel the process. What remains in the drum is recovered steel and solid char, which can be upgraded into recovered carbon black.
What the Process Recovers
- Pyrolysis oil, a fuel and feedstock for further refining.
- Recovered steel, returned to the metals supply chain.
- Recovered carbon black, a direct substitute for virgin carbon black.

Turn Waste Tires into Revenue
Klean’s rotary-kiln tire pyrolysis plants recover oil, steel and carbon black from end-of-life tires instead of sending them to landfill or incineration.
Klean Industries has delivered three recovered carbon black plants in India over the past two years, with a further five under letter of intent.
