Canada’s first carbon capture cement plant launches in Ontario

Carbon and resource utilisation firm Carbon Upcycling Technologies and cement manufacturer Ash Grove have broken ground on a first-of-its-kind commercial carbon capture and utilisation facility at Ash Grove’s cement plant in Mississauga, Ontario.

Dubbed Carbon 1 Mississauga, the project will permanently sequester carbon dioxide from the cement kiln at the facility and utilise it to produce up to 30,000 tonnes of low-carbon supplementary cementitious materials a year.

The project will utilise Carbon Upcycling’s CUT CO2 system, which captures CO2 directly from flue gas and reacts it with industrial byproducts inside a modular reactor.

The process accelerates mineral carbonation, embedding the CO2 permanently in solid form and creating performance-enhancing carbonated supplementary cementitious materials that can replace up to 50% of clinker – a key binding component – in cement.
