Green360 Technologies Ltd, Australia’s only hydrous kaolin producer, has unveiled a breakthrough in low-carbon cement production using red mud and kaolin from its Pittong mine in Victoria.
The company has commenced commercial-scale validation of its proprietary cement blends and is partnering with West Australian precast concrete specialist PERMAcast to test the material in real-world applications across key sectors in the US and Europe.
Speaking to S&P Global Market Intelligence, Aaron Banks, executive chairman of Green360, said the technology offers a potential paradigm shift in how industrial byproducts — including red mud, a residue from alumina refining, and delithiated spodumene from lithium processing — can be repurposed into valuable, low-carbon building materials.
“Instead of storing tailings in dams, we can integrate our technology directly into mine operations, converting waste streams into supplementary cementitious materials or fully-fledged binders,” said Banks. “We see a clear path to substituting up to 80 per cent of Portland cement in some applications and ultimately aim to eliminate it altogether.”
Further collaborations are underway, including a planned trial with a major gold producer to assess tailings for cement production and interest from a lithium hydroxide facility in Saudi Arabia. Green360 is also exploring global licensing and royalty models for wider deployment of the technology.
The company’s strategy aligns with mounting industry and regulatory pressure to reduce emissions and address mine waste. “This is about embedding circularity at the mine gate,” Banks said. “There’s real potential to turn an environmental liability into a value-added product.”
