Amrize (NYSE: AMRZ) broke ground on the modernization of its Saint-Constant Cement Plant, marking the largest cement industry investment in Canada over the last decade. The project aims to transform the facility into the most advanced and sustainable cement plant in Eastern Canada, strengthening the local cement supply to meet growing construction demand in Quebec and across Canada. This initiative reflects Amrize’s plan to invest across its operations to expand production, improve efficiency, and best serve customers.
The modernization will introduce state-of-the-art operational efficiency and enhanced sustainability, while expanding local manufacturing and production capacity. Key improvements include modern, high-efficiency equipment to boost production, energy efficiency, storage, and logistics. The plant expects to improve its net carbon footprint by over 40% by 2035, offering the lowest carbon emissions per tonne of cement in Eastern Canada. Additionally, the project will expand the plant’s production capacity by 300,000 tonnes to a total of 1.2 million tonnes annually and grow the plant’s workforce by 25% with local teammates.
Government Support
The modernization initiative benefits from support under the Government of Québec’s ÉcoPerformance program and the Support Measure for the Decarbonization of the Industrial Sector (MADI), both part of the 2030 Green Economy Plan and funded by the Quebec Carbon Market. Additionally, the project is funded in part by the Government of Canada’s Low Carbon Economy Fund (LCEF). These measures align with plans by the Canadian and Quebec governments to invest nearly $10 billion over the next decade to expand local infrastructure, public transportation, healthcare facilities, and housing.
