Gypsum industry news

North America: France-based Saint-Gobain has appointed Steve Williams president of its newly created construction chemicals North Americas unit. The unit combines GCP Applied Technology's speciality construction chemicals business and Chryso. Saint-Gobain acquired both GCP Applied Technology and Chryso in 2021.

Steve Williams previously worked as Chryso's North America president from 2019. Prior to this he was cement producer Titan America's sales and marketing director between 2012 and 2015. Williams holds a bachelor of science degree from Brigham Young University and a master’s in business administration (MBA) from the University of Florida.

US: The producer price index (PPI) of gypsum building materials ended September 2022 at a new all-time high of 351, up by 20% year-on-year from 292 in September 2021. The figure doubled decade-on-decade from 177 in September 2012. In the shorter term, it rose by 12% from 315 over the six-month period from March 2022, and by 3.8% from 338 over the three-month period from June 2022.

US: The city council of Glenwood Springs in Colorado is aiming to implement single-haul refuse collection in order to eliminate the dumping of recyclables by 2023, local press has reported. A review of waste management practices found that the city has a recycling contamination rate of just 8%, yet 80% of waste sent to landfill consists of recyclable materials. Eagle County Recycle operates the city's waste management facility. The company says that it supplies waste cardboard for gypsum wallboard backing production in neighbouring Oklahoma.

Manager Jesse Masten said “The mill in Oklahoma that we send the cardboard to actually makes the paper backing for wallboard. Then, that paper backing is potentially sent back to the American Gypsum gypsum wallboard plant in Gypsum and used for the wallboard that they’re producing.”

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: Gypsum wallboard producers sold 1.32Bnm² of gypsum wallboard in the first half of 2022, a similar amount to that in the first half of 2021. Total supply of gypsum fell by 2% to 20.3Mt from 20.8Mt. This was due to decline in mined gypsum supplies, although imports rose and synthetic gypsum supply remained the same.

Exports of gypsum wallboard fell slightly year-on-year to 18.6Mm² throughout the second quarter of 2022, up by 10% year-on-year from 16.9Mm². Canada received 95% of US gypsum wallboard exports. The US imported 22.9Mm² of gypsum wallboard from eight countries. The figure corresponds to an increase of 10% year-on-year and 3% quarter-on-quarter. Mexico supplied 91% of US gypsum wallboard imports, followed by Canada with 8%.

Earlier 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.

US: 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: Eagle Materials offset higher energy and maintenance costs by raising the prices of its products in the first quarter of its 2023 financial year. This contributed to an 18% year-on-year sales rise to US$561m. The group achieved earnings before interest, taxation, depreciation and amortisation (EBITDA) of US$184m during the quarter, up by 13% year-on-year.

President and CEO Michael Haack said "Our results this quarter exceeded our expectations, as our portfolio of businesses performed well, and we executed on the opportunities available to us. Construction activity remained healthy across our markets, and we realised broad pricing gains across our portfolio again this quarter."

The producer’s light materials sales rose by 30% year-on-year to US$248m due to increased gypsum wallboard sales volume and prices. Wallboard volumes increased by 5% to 74.1Mm2; their average price increased by 24%. Haack said “In our light materials sector, wallboard shipments and orders remain strong, but we recognise quantitative tightening will likely have an impact on residential construction activity in the future. In the near term, we expect record home construction backlogs to support product demand this year. With Eagle's excellent balance sheet, the favourable geographic positioning of our operations and consistent execution of our operating strategies, we are poised for a strong fiscal 2023."

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: Gypsum wallboard companies sold 629Mm² of gypsum wallboard in the first quarter of 2022, in line with first-quarter 2021 sales, according to US Geological Survey (USGS) figures. They exported 16.9Mm², up by 6% year-on-year from first-quarter 2021 volumes. Canada received 15Mm², 94% of exports. The US Census Bureau recorded gypsum wallboard imports of 22.2Mm², up by 28% year-on-year. Mexico supplied 19.1Mm² (86%), while Canada supplied 2.89Mm² (13%).

In the first quarter of 2022, national natural gypsum production was 5.33Mt, up by 2.1% year-on-year from 5.22Mt in the first quarter of 2021.
