Study finds use of reclaimed clay and brick dust reduces embodied carbon content of cement

UK: A new study by the Mineral Products Association (MPA), supported by Innovate UK, has found that incorporating reclaimed clays and finely ground brick powder into cement production can reportedly lower the embodied CO₂ by up to 3%. The materials are used as calcined clay in the cement production process. The project aims to offer a viable alternative to fly ash and ground granulated blast-furnace slag, as resources diminish due to the steel industry's decarbonisation efforts.

MPA director Diana Casey said "Using discarded bricks and reclaimed clays will not only lower carbon and reduce the amount of materials sent to landfill but has the potential to create a whole new market if these clays become widely used in the construction industry, helping to retain economic value in the UK, secure jobs and attract investment."
