Mineral Carbonation International (MCi) is an Australian based company which is developing technology for carbon capture and use (CCU). Its priority is large scale transformation of CO2 into valuable products through mineral carbonation processes. This would assist as a transition technology for the major emitting countries as they move away from carbon intensive power generation to more sustainable energy mixes and decarbonizing industrial processes.
MCi aims to transform CO2 into stable carbonates and silicates for use in building products like cements, plasterboards and other valuable industrial products. MCi aims to be part of the rapidly emerging carbon industry which uses CO2 as a raw material not as a waste emission.
MCi’s process reacts captured CO2 with quarried low grade minerals in a continuous industrial process. This mimics but greatly speeds up the natural weathering by rainfall which produces common types of rocks over millions of years. It is anticipated that the MCi process will be economically viable even without a high carbon price.
Once proven feasible mineral carbonation plants operating at industrial scale around the world could limit further emissions from big greenhouse gas emitters in cement, steel making and power generation.
