Saint-Gobain Canada announces that over the past year, CertainTeed Gypsum Winnipeg has spearheaded a sustainability project to conserve water and energy use during gypsum wallboard production. This project reportedly resulted in reducing water consumption by 3%, decreasing CO2 emissions (scopes 1 and 2) by 5.6 tons per year for the site and decreasing energy consumption by nearly 25 million kWh per year, according to a press release by Saint-Gobain Canada.“At Saint-Gobain Canada, our team is striving every day to manufacture and deliver the highest quality of product to the construction industry while actively reflecting on the impact of our actions,” shares Jean-Claude Lasserre, CEO, Canada, Saint-Gobain. “With this transformative project, our whole CertainTeed Gypsum Winnipeg team came together to solve a challenge that will have a significant sustainable impact on our work, the environment and our customers.”In 2024 the CertainTeed Gypsum Winnipeg team embarked on a journey to try and reduce overall water use – an essential component of gypsum wallboard production – as well as the amount of energy consumed during the evaporation and drying process. Prior to the project, only one-third of the water added in production was reportedly retained in the product, while the rest was evaporated in the drying process, leading to higher energy consumption.Through an iterative process, Saint-Gobain Canada says that its team identified a key product line, the CertainTeed 5/8 Type X board, to conduct trials to adjust the water-to-stucco ratio (known as water gauge), while working to maintain product quality. Some of the achievements from the trials reportedly include:Recipe optimization: After several trial phases, the Winnipeg team says it reduced the water gauge, achieving a 3% reduction;Technology upgrade: Additionally, by replacing the magnetic flow meters with the newer technology, Coriolis flow meters, the team improved water measurement accuracy;Energy savings: With lower water content in the product, the process has a reduced dryer evaporation load, decreasing energy consumption;Carbon emissions: With this newly implemented process and other actions, the facility measured reduced carbon emissions of 5.6 tons/year of CO2 (scopes 1 and 2)Production efficiency gains: Saint-Gobain Canada says that the new process also increased line speed and increased productivity by 5%.
