Amrize Ltd (AMRZ) gained 2.05% to $55.35 after the company launched a major cement plant modernization in Quebec. The stock climbed above $56.50 intraday, then eased before closing near $55.30. The move followed a project that targets higher cement output, lower emissions, and stronger local supply.
Amrize Starts Major Quebec Cement Plant Upgrade
Amrize broke ground on the modernization of its Saint-Constant cement plant outside Montreal. The company said the site will become the most advanced cement plant in Eastern Canada. The project marks the largest investment in Canada’s cement industry over the past decade.
The upgrade will add modern equipment across production, energy use, storage and logistics. As a result, Amrize expects stronger efficiency and better operational control at the plant. The company also plans to expand output while keeping more cement production inside Quebec.
The Saint-Constant plant currently plays a major role in regional construction supply. After the upgrade, annual capacity will rise by 300,000 tonnes to 1.2 million tonnes. In addition, Amrize expects the plant workforce to grow by 25% with local employees.
Project Targets Lower Emissions and Local Supply
Amrize said the plant should cut its net carbon footprint by more than 40% by 2035. The company also expects the site to offer the lowest cement emissions per tonne in Eastern Canada. Therefore, the upgrade links production growth with lower industrial emissions.
The company plans to market cement from the site as manufactured in Quebec. That label will cover raw materials, processing, and final production within the province. This approach supports local jobs, regional supply chains, and nearby construction demand.
Government programs will support measures that reduce greenhouse gas emissions at the plant. These include Canada’s Low-Carbon Economy Fund and Quebec’s ÉcoPerformance program. Quebec’s industrial decarbonization support measure will also help fund cleaner production work.
Cement Demand Rises Across Quebec Infrastructure
The modernization comes as Canada and Quebec prepare major infrastructure spending. Both governments plan nearly $10 billion in investments over the next decade. The spending targets public transportation, healthcare facilities, housing, and other local infrastructure needs.
Amrize linked the project to rising demand for reliable cement across Quebec and Canada. The company said local production should help serve construction needs more directly. The upgrade strengthens supply as public and private building activity expands.
Amrize has operated in Quebec for more than 70 years. Its materials have supported projects including the Montreal Metro Blue Line and the Samuel Champlain Bridge. The company has also supplied major sites such as Montreal Trudeau International Airport and Place des Montréalaises.
