Lafarge Canada completes transition to greener cement at St-Constant plant

TORONTO — Lafarge Canada announces the completion of another important milestone in the company’s commitment to drive sustainability – the full transition of production from traditional general-use cement to OneCem®, a greener product that results in lower CO2 emissions, at St-Constant Cement Plant in Quebec.

“We are excited to take another crucial step in our sustainability journey. The transition to OneCem production at our St-Constant plant indicates Lafarge Canada’s nonstop commitment to driving positive change within our construction industry. Our teams have been engaged in reducing our products’ environmental impact by embracing greener practices and materials,” expressed David Redfern, president & CEO of Lafarge Canada (East).

OneCem® is a limestone blended cement manufactured using less clinker than traditional Portland cement. By converting the St-Constant Plant’s production to OneCem, Lafarge Canada projects a reduction of about 60,000 tonnes of CO2 emissions in 2024. This equates to CO2 emissions from 16,267 passenger vehicles or 877,972 tree seedlings grown for 10 years.

The St-Constant plant has been trying to reduce emissions in cement production in Quebec for many years. Building upon its achievements in carbon reduction, the plant has implemented initiatives such as circularity through ECOcycle, as well as collaborating with organizations like CarbiCrete and Patio Drummond to facilitate the production of zero-carbon concrete.

“Our team at St-Constant is proud to be taking actions towards sustainability. With this transition, we are not only reducing our carbon footprint but also aligning with our organization’s drive to be a leader for sustainable construction throughout Eastern Canada,” added Andrew Stewart, Vice President of Cement, Lafarge Canada (East). “This is a significant development, and we are eager to contribute to the realization of a net-zero future.”
