In a context where environmental issues are more than ever at the heart of priorities, the City of Quebec has undertaken the construction of its Biomethanization Center, an innovative infrastructure designed to transform organic residues and municipal sludge into sustainable resources. Located in the Limoilou district, this center plays a key role in reducing landfill waste and producing biogas, which is valorized under an agreement with the renewable natural gas distributor Énergir. With its capacity to process 182,600 tonnes of organic matter per year, the center also contributes to the production of a natural fertilizer while reducing greenhouse gas emissions, reinforcing the city’s commitment to sustainable development.

As part of this project, our team was commissioned to ensure the quality control of the materials used, in particular aggregates, cement concrete and bituminous concrete. We also provided our expertise in geotechnics and building envelope design, to guarantee the conformity of materials and the durability of the infrastructure. The result is a high-quality facility that meets both technical and environmental requirements, and is ready to play a key role in the city’s sustainable waste management.
