Australian environmental technology company Calix Limited has signed an MOU with a leading aluminium producer to advance its Zero Emissions Alumina (ZEAL) technology. The agreement includes pilot-scale testing and a pre-FEED study at Calix’s Technology Centre in Victoria, generating over AUD 1 million in revenue.
ZEAL uses electric calcination to replace fossil fuels in alumina refining, aiming to cut emissions, lower costs, and improve product quality. Calix will retain IP rights and jointly design scalable systems for commercial deployment. The aluminium industry accounts for about 2% of global CO₂ emissions, with alumina refining being one of its most energy-intensive steps.
