Saving the world, one brick at a time

Mitsubishi looks to advance CO2 capture in concrete, according to Construction Europe magazine.

Mitsubishi Corporation (MC) is researching the possibility of injecting waste CO2 into concrete, to help reduce the industry’s carbon emissions.

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.
