The numerous facility upgrades also helped decrease energy usage by up to 30% and boost production capacity by up to 40%, as Saint-Gobain works to provide gypsum wallboard in Canada to help respond to the increasing housing demand across the country.
With the new process and equipment, CertainTeed’s plant has reduced its CO 2 emissions by 44,000 tons per year – which is equivalent to the average emissions of 14,000 cars annually. This milestone also marks the launch of a new Infinaé gypsum wallboard category in Canada, within which CarbonLow, produced locally, is estimated to have up to 60% less embodied carbon cradle-to-gate.
Infinaé is Saint-Gobain’s highest performance, lowest climate impact range of gypsum solutions engineered to lead the way in construction with products made right here in Canada. It offers Canadian customers the freedom to surpass current green building standards.
Strong partnerships to further Quebec’s energy transition
The project represents a major investment that was conducted in partnership with both Quebec’s government and Hydro-Québec. Through the Ministry of the Environment, the Fight against Climate Change, Wildlife and Parks’ EcoPerformance program, the Sainte-Catherine plant was granted $40M to support this important energy transition and energy efficiency project.
A three-year transformation for the better
Overall, 80% of the plant’s equipment was upgraded through this three-year project and new processes were implemented to significantly reduce carbon emissions:
Additional improvements are being implemented and will be deployed in the near future to further improve sustainability at the site:
