Saint-Gobain To Install Heat Recovery Technology

Saint-Gobain, through its building products subsidiary CertainTeed Canada Inc., will install heat recovery technology at its gypsum wallboard plant in Vancouver, BC, reducing the plant’s carbon dioxide emissions by 10 per cent and improving the energy efficiency of the facility. The investment comes only months after it announced its global ‘Grow and Impact’ strategy, which includes plans to reduce the company’s energy consumption and emissions. Gypsum wallboard is made from a gypsum slurry that is poured and dries between two sheets of paper. During one step in this process, the wallboard passes through a large, heated dryer that helps solidify the wallboard and remove moisture from the product. In Vancouver, the company will install a large heat exchanger on its industrial dryer. The heat exchanger will capture and recycle some of the warm air emitted from the dryer, allowing the plant to maintain the dryer’s temperature while consuming less energy and ultimately reducing the facility’s carbon dioxide emissions.
