Gypsum industry news

US: Saint-Gobain subsidiary CertainTeed's Buchanan gypsum wallboard plant in New York has successfully participated in a gypsum wallboard recycling pilot. Together with contractors Structure Tone and Cooper Recycling, it processed 20t of gypsum from waste wallboard in its gypsum wallboard production.

CertainTeed interior products vice president and general manager Jay Bachmann said "For us to achieve our sustainability goals, we must change the way we think. By partnering with organisations in the community like Cooper Recycling and Structure Tone, we can get there faster." Bachmann continued, "As the only gypsum manufacturing plant in New York, our colleagues in Buchanan were able to create a true circular economy. From the creation of drywall products to construction, to processing scraps and back into drywall production, the material is continuously used and never leaves the state. This maximises our company's positive impact while working to minimise our environmental footprint. Our Buchanan plant has increased our capacity to reuse recycled material, and we look forward to growing this successful pilot into a long-term programme, while working with builders and recyclers across the state. Partnering with CertainTeed, New York builders have the opportunity to not only reduce waste at their job sites, but also gain Leadership in Energy and Environmental Design (LEED) points on their projects."

The Buchanan plant joins CertainTeed's units at Nashville in Arkansas and Palatka in Florida in supporting the company's circular economic efforts in the US. The Nashville plant commissioned a 65,000t/yr line in May 2022, while the Palatka plant increased the recycled content of its wallboard by 18,000t/yr in August 2022. The Palatka plant plans to install a new 100t/hr Rotochopper grinding unit to replace its existing trommel machine in its reclaim processing and screening operations.

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.
