Turning tyres into steel

Supported by an ARC Linkage Projects grant, the University of New South Wales (UNSW) and OneSteel teamed up to use a polymer technology to recycle rubber tyres in steelmaking, enabling the partial replacement of coal and coke. This revolutionary approach has already diverted more than two million car tyres from landfill and reduced greenhouse gas emissions.

Originally supported by an ARC Discovery Projects grant for basic research, ARC Laureate Fellow, UNSW Scientia Professor Veena Sahajwalla, invented a new polymer technology—an invention that won her an Australian Museum Eureka Prize.

Professor Sahajwalla partnered with OneSteel on an ARC Linkage Projects grant to translate this invention into a practical use, including carrying out polymer injection technology trials in steel plants across Australia and Thailand.

UNSW has signed an agreement with OneSteel—Australia’s largest manufacturer of steel long products—which allows OneSteel to sublicense this unique technology around the world.
