Kal Tire is redefining sustainable practices in the mining sector through its advanced recycling facility in Antofagasta, Chile, which focuses on the recovery of ultra-class mining tires. Opened in 2021, the plant uses a proprietary thermal conversion process that transforms end-of-life tires into valuable resources such as alternative fuel, high-tensile steel, and recovered carbon black (rCB).

A standout innovation is Kal Tire’s in-house technology for refining carbon black. The recovered material is further purified and pelletized to meet the strict performance requirements of Tier 1 tire manufacturers and other industrial applications.

Designed for scalability, the facility aligns with Chile’s progressive tire disposal legislation and is built to withstand seismic activity. It operates in a closed-loop system, harnessing synthetic gas produced during pyrolysis to power the plant itself. The plant is certified under the ISCC PLUS sustainability program, underscoring Kal Tire’s commitment to traceability and circular economy principles.

With growing interest from other mining regions, Kal Tire’s model demonstrates a viable and replicable path forward for sustainable management of mining tires worldwide.
