CO2 Capture
Turning waste streams into value through carbon management solutions
Summary
CO₂ mineralisation locks carbon away permanently, but the reaction typically requires an alkali to drive it, and purchasing ammonia, sodium hydroxide, or lime at industrial scale is what often undermines the economics.
This technology addresses these challenges by utilising readily available industrial waste streams to facilitate the conversion of CO₂ into stable mineral products, while simultaneously valorising waste materials. The process operates under mild conditions and produces mineral products with potential industrial applications. Laboratory studies demonstrated rapid mineralisation and the production of high-purity mineral products with reduced contaminant leaching.
Carbon abatement potential is governed by the alkalinity available in the ash and brine per tonne processed, and storage is permanent because the CO₂ becomes stable carbonate mineral.
What makes this novel compared to best-in-class technology?
Unlike conventional approaches that address waste treatment and carbon capture separately, this technology integrates both objectives into a single process, creating value from waste streams while supporting long-term carbon storage.
