Gypsum industry news

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.

US: CertainTeed has completed a US$1.3m upgrade to its Nashville wallboard plant in Arkansas to use recycled waste gypsum and paper. The plant will reuse 65,000t/yr of waste materials generated from the production process. The company plans to increase the amount of recycled materials in its gypsum wallboard in the future.

“In Nashville and at our manufacturing sites around the world, we remain laser-focused on reducing waste, reducing our consumption of natural resources, and increasing recycling and circularity throughout our value chain,” said Jay Bachmann, Vice President and General Manager of CertainTeed Gypsum.

US: The US Department of Energy has awarded CertainTeed its 2022 Better Project Award for the company’s installation of a 15,000t/yr production scrap paper recycling system at its Silver Grove, Kentucky, gypsum wallboard plant. The plant recycles ground paper and gypsum from the system in its gypsum wallboard production.

CertainTeed vice president environmental, social and governance North America and Saint-Gobain circular economy solutions managing director Dennis Wilson said "Our recycling technology in Silver Grove allows us to reduce our waste, reduce our consumption of natural resources and also reduce our production costs - all while continuing to produce the best gypsum wallboard product on the market.” Wilson continued “We will continue to look for ways to minimise our environmental footprint while striving to maximise our company's positive impact for our customers and the communities where we operate."

Canada: Saint-Gobain has shared plans to install a US$3.19m waste heat recovery (WHR) system at its Vancouver gypsum wallboard plant in British Columbia. It has secured US$1.12m in funding from the provincial government’s CleanBC Industry Fund for the project. The producer says that the installation will increase the plant’s energy efficiency and reduce its CO₂ emission by 10%.

Saint-Gobain said “This project will help our company to maximise our positive impact for our customers and the communities where we do business, while minimising our environmental footprint. We thank the CleanBC programme for its support, and look forward to many more years of sustainable, state-of-the-art manufacturing in Vancouver.”

Canada/US: Saint-Gobain North America and its subsidiary CertainTeed say they have reduced their CO₂ emissions from electricity usage by about a third in 2021 through the use of renewable energy contracts. In February 2020, Saint-Gobain entered into a 12-year virtual power purchase agreement with the Blooming Grove Wind Farm in McLean County, Illinois. At the time, the agreement was the largest renewable energy deal in Saint-Gobain’s 356-year history. Saint-Gobain worked with Edison Energy, an industrial energy advisor, on the arrangement.

“We’re thrilled with the results of our partnership with the Blooming Grove Wind Farm, and will continue to look for ways to maximise our positive impact, for our customers and the communities where we do business, while minimising our environmental footprint,” said Mark Rayfield, the chief executive officer of Saint-Gobain North America and CertainTeed. “In this next chapter of our company’s history, our team will strive to lead our industry towards a more sustainable future.”

US: CertainTeed has installed new recycling technology at its Silver Grove, Kentucky, gypsum wallboard plant which will enable the facility to divert 15,000t/yr of production scrap paper from landfill. The technology grinds gypsum-contaminated paper into fine pieces for separation. The subsidiary of France-based Saint-Gobain says that it will then be able to reuse both paper and gypsum in its wallboard production at the plant.

CertainTeed’s gypsum general manager and vice president Jay Bachmann said “This project allows us to reduce our waste and reduce our production costs in Silver Grove while also empowering us to increase the efficiency of our use of natural resources.” He added “We will continue to look for ways to minimise our environmental footprint while maximising our company’s positive impact for our customers and the communities where we do business.”

US: CertainTeed plans to establish a new gypsum logistics facility in Jacksonville, Florida. The Saint-Gobain subsidiary plans to integrate a terminal dock operation on the St Johns River with environmental restoration of the riverside at an additional cost of US$70m. The site previously belonged to Kerr-McGee Chemical Corporation until 1978.Construction is due to begin in 2022 and reach completion before 2025. Once operational, the dock will be equipped with a bulkhead, a conveyor, an unloading ramp, truck staging areas and a small office. The site will employ an estimated 32 people.

Vice president and general managerJay Bachmann “We are deeply grateful to the City of Jacksonville for their support of our new logistics facility on the St Johns River, and we look forward to continuing our partnership with Greenfield to ensure the responsible stewardship of this Superfund site.” He added “This project will return a heavily contaminated Superfund site to productive use, creating dozens of full-time jobs and strengthening our company’s ability to serve our customers.”

US: CertainTeed soil conditioner and soil amendment subsidiary Western Mining and Minerals has taken over management of the former CertainTeed gypsum wallboard plant site in Cody, Wyoming. The Cody Enterprise newspaper has reported that the plant will produce gypsum for agricultural purposes. The producer decommissioned the former wallboard plant in December 2020 after it ceased production in January 2020.

US mining operations manager Roberto Margutti said, “With the agri-gypsum business (and other business opportunities generated with the mine operation), we expect to grow the team from 30% to 50% in the next three to five years.” He added, “We are pleased to be building our new operation with support from many of the same employees who have worked in our drywall plant previously, who will now help operate and manage the agricultural gypsum business.”

Canada: CertainTeed Canada plans to close its McAdam gypsum wallboard plant in New Brunswick by the end of February 2021. It said that the decision was made after ‘an extensive review of our business,’ according to the Canadian Broadcasting Corporation (CBC). 50 employees are expected to lose their jobs, although the subsidiary of France-based Saint-Gobain says it will try to find roles at other CertainTeed and Saint-Gobain plants for them.
Production will stop at the unit at the end of August 2020. The plant will then continue using inventory until February 2021 with a skeleton staff. The plant was reported to be operating at 22 – 25% production capacity. The closure has been blamed on a decline for wallboard products in the Atlantic Canada region and elsewhere.

US: The Gypsum Association has elected Gregory McCown as the chair of its board of directors for 2020 – 2021. McCown is the Regional Manufacturing Manager – Eastern US for CertainTeed Gypsum. Other appointments include National Gypsum’s Craig Robertson as vice-chair, Pabco Gypsum’s Emil Kopilovich, as treasurer and the Gypsum Association's Stephen H Meima continues as the secretary. USG’s Albert R Zucco is the past chair of the board. All terms are for one year and are effective from 1 May 2020.
