CertainTeed recycles gypsum wallboard at Buchanan plant
14 October 2022US: 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.
Canada: Saint-Gobain has named Julie Bonamy Racine as the chief executive officer (CEO) of its subsidiary CertainTeed Canada. She succeeds Richard Juggery, who led the company for four years before being named CEO of Saint-Gobain Benelux in July 2022. She will also be CertainTeed Canada's first female CEO.
Bonamy previously worked as the CEO of Saint-Gobain Malaysia, Singapore and Indonesia. She joined the company in 2017 in Paris as Group Vice President, Strategy & Planning. Earlier in her career, Bonamy worked in the public sector, most recently as an adviser for the budget and digital sector for the Office of the French Minister for the Economy. She is a graduate of the Paris Institute of Political Studies (IEP de Paris) and the National School of Public Administration (Ecole Nationale d'Administration).
Update on gypsum supplies, August 2022
31 August 2022Earlier this month the German Gypsum Association (GIPS) gave its approval for an inventory of natural gypsum deposits in Germany that was presented at the Conference of Economics Ministers that took place in early July 2022. The Federal Commission on Geosciences (BLA-GEO) had previously been given the job of taking an inventory of deposits and this was then put in front of the policy makers. The association’s stance was all about securing future supplies. In its view there will be no large-scale alternatives to natural gypsum supplies in the foreseeable future due to low recycling rates and falling production of flue gas desulfurisation (FGD) gypsum as coal power plants are shut down. So a list of where natural gypsum might be found is the start of conversations about which ones might be mined. Readers who are interested can download the inventory of German gypsum deposits here.
Security of supply of raw materials has been in the air since the end of the coronavirus lockdowns started to cause supply chain disruption around the world and the Russian invasion of Ukraine further exacerbated this and rocked energy markets. Part of the reaction to this new reality could be seen in a conference that the Federal Institute for Geosciences and Natural Resources (BGR) and the German Resource Research Institute (GERRI) ran, also in early July 2022. The state of German gypsum supplies was presented at this event too. The BGR-GERRI conference came up with a ten-point plan to strengthen the supply of raw material. Some of these recommendations were to grow domestic raw material extraction, expand recycling and the circular economy and keep supply chains closer internationally, ideally within Germany and Europe.
A focus on gypsum supplies isn’t restricted to Germany though. The issue arose in late July 2022 during an earnings call for US-based Eagle Materials’ first quarter results. These kinds of questions from analysts about supply of raw materials are common for a public company but it reinforces the general declining trend around the world of synthetic gypsum supplies. Craig Kessler, the chief financial officer of Eagle Materials, mentioned that a scarcity of synthetic gypsum might be creating cost pressures for other gypsum wallboard producers. Although he was quick to describe his company as a “natural gas or natural gypsum oriented business.” The wider picture in the US is that the ratio of natural to synthetic gypsum production has grown over the last decade. United States Geological Survey (USGS) data shows that it was 37% / 49% in 2011 compared to 53% / 32% in 2021, with the remainder imported in each year.
One more point to make here is that many of the new gypsum wallboard plant projects announced in the over the last few months have involved recycling in one form or another. For example, Siniat’s forthcoming wallboard plant in Bristol in the UK aims to achieve 30% post-consumer gypsum recycling. CertainTeed’s current upgrade plans for its Palatka plant in Florida are also recycling-based. Similarly, the subsidiary of Saint-Gobain also completed an upgrade in June 2022 to allow more recycling at its Nashville plant in Arkansas.
Finally, some of the thinking in Germany and elsewhere has been influenced by the current geopolitical situation in Ukraine. However, one potential consequence of prolonged disruption to European energy markets could be a delay to the decline of coal power plants as plant lifespans are elongated or even new ones built. This in turn could mean more synthetic gypsum supplies in Europe in the short to medium term. How all of this plays out in the placement of new gypsum wallboard plants in Europe over the next few years will be interesting to observe.
CertainTeed to upgrade Palatka gypsum wallboard plant in Florida with recycling equipment
31 August 2022US: CertainTeed plans to spend US$1.1m towards installing recycling equipment at its Palatka gypsum wallboard plant in Florida. The upgrade will increasing the recycled content of its wallboard products manufactured at the unit by 18,000t/yr while also reducing the site’s CO2 emissions by 2260t/yr.
The new recycling equipment at the Palatka plant will work by grinding the waste gypsum and waste paper down into fine particles, allowing the plant to capture and internally recycle the materials, which are sorted and then reintroduced to the production process at the plant. The kit will be powered by electricity and will replace older machines currently powered by diesel, lowering the plant’s Scope 1 Emissions from its operations. Additionally, by consuming more recycled gypsum, the plant will become less reliant on feedstock that is shipped to the site from external sources, allowing the unit to also reduce Scope 3 Emissions associated with transporting the feedstock.
Jay Bachmann, the Vice President and General Manager of CertainTeed Interior Products Group, said, “The new technology in Palatka will allow us to increase the recycled content in our products, reduce our carbon CO2 at the plant, and strengthen our operations at a time of unprecedented consumer demand for gypsum wallboard in the south-eastern US.”
The investment at the Palatka plant follows similar investments that will increase the recycled content of wallboard made at CertainTeed’s wallboard plants in Silver Grove in Kentucky and Nashville in Arkansas. Parent company Saint-Gobain continues to roll out its global ‘Grow and Impact’ strategy, which includes reducing waste and increasing recycling efforts at its manufacturing sites.
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.
CertainTeed’s Silver Grove gypsum wallboard plant’s paper recycling facility wins 2022 Better Project Award
19 May 2022US: 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."
Saint-Gobain to install waste heat recovery system at Vancouver gypsum wallboard plant
31 March 2022Canada: 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.”
CertainTeed installs 15,000t/yr recycling line at Silver Grove gypsum wallboard plant
06 January 2022US: 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.”
