Tire Pyrolysis

Continuous thermal processing of end-of-life tires into recoverable resources.

What it is

Gangjin's tire pyrolysis system thermally decomposes End-of-Life Tires (ELTs) in an oxygen-free reactor at 400–600°C. Through continuous processing, waste tires are converted into four commercially valuable resources — pyrolysis oil, carbon char, steel wire, and non-condensable gas — with the raw char further upgraded into commercial-grade recovered carbon black through our downstream rCB Refinery System.

Technology & Engineering

Paddle-Type Continuous Reactor

GANGJIN’s proprietary paddle-type reactor is designed to promote uniform material transport and heat transfer throughout the reaction zone, supporting efficient and stable continuous operation.

Multi-Barrier Oxygen Sealing

A plug-screw sealing system prevents oxygen ingress into the reactor, protecting oil quality and operational safety. Additional sealing stages can be applied — in double or triple configuration — to meet site-specific requirements.

Water-Jacketed Continuous Discharge

Jacketed discharge conveyors continuously cool and extract solid char, improving handling safety and downstream rCB quality.

NCG Energy Recovery System

External LPG or LNG is required during start-up. As the reactor reaches operating temperature, recovered NCG supplies 60–70% of its heating demand and can ultimately sustain reactor heating without additional external fuel. Water-seal safety tanks prevent burner backfire, while excess gas is safely routed to a thermal oxidizer / RTO.
