The CO2 would be drawn from the processes of, for example, steel mills, power plants and cement manufacturing facilities.

The Tokyo-based multinational says the CO2, once embedded in concrete, will mineralise and remain permanently locked in.

MC said most of the current carbon-recycling technologies are mainly used for a limited scope of unreinforced concrete, such as concrete blocks, so the challenge now is to enhance their mineralisation capabilities and broaden their applications.
