The Pyrojin waste tyre batch pyrolysis plant converts whole or shredded waste tyres into fuel oil, recovered carbon black and steel wire through oxygen-free thermal cracking. It is designed for small and medium-scale operators processing roughly 1-15 tonnes of tyres per day, and it accepts whole tyres, so feed preparation is kept to a minimum.
How a Waste Tyre Batch Pyrolysis Plant Works
- Whole or shredded tyres are loaded into the horizontal rotary reactor.
- The reactor is sealed and heated indirectly in a low-oxygen environment, so flame never contacts the feedstock.
- Staged temperature control breaks the tyre polymer into oil vapour and non-condensable gas.
- The oil vapour is condensed into liquid fuel oil; the remaining gas is routed through a water-seal safety device back to the furnace for combustion.
- Flue gas passes through a spray tower for acid-base neutralisation (desulphurisation), then an adsorption tower, before discharge under the project's permitted limits.
- Solid residue is discharged as carbon black; the steel wire is separated by magnetic recovery (around 15% of tyre weight) and sold as scrap metal.
The system runs as a closed loop for resource recovery with no open-flame contact and controlled emissions.

Main reactor: thick-walled boiler steel with high-temperature annealing, rated for 10,000+ heating cycles. Rotation speed 0.4 rpm; circulating water cooling; noise ≤85 dB; installation footprint approx. 35 m × 20 m; 4-6 operators per shift.
Outputs and Yields
- Fuel oil (40-45%) - used in industrial boilers, heavy equipment and generators, and can be further refined into diesel.
- Recovered carbon black - feedstock for rubber, plastics and activated carbon.
- Steel wire (≈15%) - recovered magnetically and sold as scrap metal.
Key Equipment Features
- Low investment cost and compact footprint for fast payback.
- External gear-ring drive for quiet, stable rotation.
- Indirect heating for uniform temperature control and longer reactor life.
- Combustible gas recycling to cut fuel consumption.
- Fully sealed horizontal rotary design for clean, closed operation.
- Slight negative pressure with automatic submerged-arc welding and ultrasonic NDT for safety.
- Multi-furnace tandem operation to reduce heat loss.
- Oil-gas fractionation tower separating fuel oil into three density grades.
- Multi-stage flue-gas purification for acid neutralisation and dust removal.
- High-temperature sealed slag discharge for enclosed carbon-black handling.
Batch vs Continuous Pyrolysis
| Batch (PB) | Continuous (PC) | |
|---|---|---|
| Scale | ≈3,000 t/year | ≥10,000 t/year |
| Operation | One furnace per day | 24/7 |
| Automation | Moderate manpower | High (1-2 operators) |
| Feedstock | Whole tyres accepted | Pre-crushed tyres (rubber powder) |
Choose batch if you want lower upfront investment, whole-tyre feeding and a simpler system; choose continuous for high-volume, round-the-clock output.
Applications
- Tyre recyclers adding fuel-oil revenue to their existing operation.
- Fuel suppliers producing pyrolysis oil for boilers, generators and further refining.
- Industrial operators recovering steel wire and carbon black as saleable by-products.
- Municipal or regional waste-to-resource projects.
