The federal environment minister Sussan Ley has toured Waratah-based steel maker Molycop’s facilities in NSW to view in person efforts to decarbonise steel production.
Ley joined UNSW SMaRT Centre Director, Professor Veena Sahajwalla at the Newcastle steel works to see up close SMaRT’s Green Steel technology that uses waste to replace coke and coal in steel making.
Ley said on social media: “Called in to Waratah-based steel maker Molycop, to get an update on new Polymer Injection Technology at its electric arc furnace, developed in partnership with UNSW and designed to replace coking coal with discarded rubber from old tyres and conveyor belts, on the way to commercialising green steel production.
“An exciting recycling initiative, supported by the…government and internationally significant Veena Sahajwalla.”
UNSW SMaRT Centre is collaborating with Molycop to develop the next generation of SMaRT’s Green Steel ‘Polymer Injection Technology’ which uses waste rubber tyres, and other wastes such as plastics and coffee grounds, to improve the steel making process in electric arc furnaces.
In Veena’s patented Polymer Injection Technology process, a mixture of coke and recycled polymers have been shown to produce a more stable foamy slag compared to coke only – greatly improving furnace energy efficiency, and yield while reducing raw material cost.
