The Western Australian Government has partnered with the Minerals Research Institute of WA (MRIWA) to accelerate large-scale mineral carbonation using mine waste, paving the way for innovative carbon sequestration solutions.
Mineral carbonation is a naturally occurring process where CO₂ reacts with minerals to form stable solid carbonates. This method has the potential to lock away carbon emissions on a gigatonne scale, making Western Australia a leader in sustainable climate solutions.
A newly released roadmap by MRIWA outlines a clear pathway to fast-track mineral carbonation, focusing on converting CO₂ into a stable form using mining waste and byproducts. The roadmap highlights a program of work across four key themes: science and technology, economic viability, social and environmental impacts, and policy and regulatory frameworks.
“Accelerated mineral carbonation technology provides an opportunity for the state and industry to work together to convert large legacy stockpiles of mining and processing waste into valuable sequestration assets,” WA Mines and Petroleum Minister David Michael said.
“Research focused on advancing mineral carbonation technologies will play a vital role in reducing CO₂ emissions, while also creating new jobs, businesses, and markets for mineral carbonate products in Western Australia.”
The roadmap is supported by a $2.5 million Accelerate Mineral Carbonation Research Program, with expressions of interest now open for participants.
“By leveraging mining wastes and byproducts, accelerated mineral carbonation offers a sustainable and scalable pathway to reduce atmospheric CO₂,” MRIWA stated.
This initiative reflects Western Australia’s commitment to driving innovation in carbon sequestration, creating economic opportunities, and addressing the global challenge of climate change.
