How Tyre Pyrolysis Works
From shredded tyre chips to pyrolysis oil and carbon char — five stages, running continuously, around the clock.
Feeding
Shredded tyre chips (approx. 20–25 mm, with minimal residual wire) are loaded into a dual-hopper feed system. Airtight valves open and close in sequence so material enters the reactor without letting oxygen in — critical, since oxygen inside the reactor could ignite the rubber instead of pyrolyzing it.
Thermal decomposition (the reactor)
Inside the sealed, rotating-screw reactor, tyre chips are heated to high temperatures in a completely oxygen-free atmosphere. Without oxygen, the rubber cannot burn — instead, the heat breaks the long hydrocarbon chains in the rubber apart, turning solid rubber into a mix of hot gas and solid carbon residue.
Condensation into oil
The hot gas released during decomposition passes through a cooling/condensing system. As it cools, most of it liquefies into pyrolysis oil, collected in storage tanks. The gas that doesn't condense (non-condensable syngas) is piped back to fuel the reactor's own burners — cutting external fuel use.
Char (carbon) recovery
The solid carbon char left behind in the reactor is cooled and discharged through a sealed conveying system, then packaged for sale or further processing into higher-grade recovered carbon black (rCB).
Emissions & safety control
Flue gas passes through a purification system before release, and the whole plant runs under negative pressure with nitrogen backup — so if pressure ever rises unexpectedly, nitrogen purges the system and safety valves open automatically.
