US: CertainTeed has completed an upgrade to the grinding control technology at its gypsum wallboard plant at Buchanan in New York state. The new variable frequency drive at the site can vary the speed at which raw gypsum is ground and save energy accordingly. It is expected to reduce the plant’s energy consumption by nearly 700,000kWh/yr. Other recent sustainable upgrades at the plant include the installation of 2.4MW solar array on its roof in 2018.
Parent company Saint-Gobain North America has announced a number of sustainability-focused upgrade projects at its wallboard plants so far in 2022. These include switching to renewable energy at its Montreal plant in Quebec, using recycled materials at its Nashville plant in Arkansas and installing a waste heat recovery system at its Vancouver plant in British Colombia.
