Gypsum industry news

One can tell that gypsum wallboard is a popular product because companies keep trying to devise alternatives to it. A recent one is Breathaboard. The company making it, Adaptavate, announced in August 2023 that it had generated around Euro2.3m in its latest investment round. It is building a pilot production line in Bristol in the UK and attempting to licence its Breathaboard product, amongst other plans. Its take on wallboard is being marketed as a sustainable substitute that is made from crop waste, that sequesters CO₂ and that then can be composted at the end of its life. It is also promoting the product’s breathability and moisture buffering capabilities, hence the name.

Another new contender hoping to steal some of the gypsum wallboard market is Xeriant’s Nexaboard product. This one uses plastic waste as its alternative to gypsum. Florida-based Xeriant said in July 2023 that it had started to buy equipment and raw materials, was running pilot production and was testing its first samples. It too is working on getting its product used in pilot construction projects.

Both of these examples, and others over the years, have taken a pop at wallboard’s sustainability credentials. Adaptavate is rather quieter about what happens to all of that sequestered CO₂ when its product is composted and Xeriant does not mention the environmental impact of making the plastic it uses in the first place. Yet, it is a valid question to ask how sustainable is gypsum wallboard? This column has covered issues with the supply of raw gypsum from either natural, synthetic or recycled sources previously, so we will stick to the general picture here.

The late-lamented consultant Bob Bruce pulled together data from various studies for the Global Gypsum Conference in 2019 to estimate the CO₂ emissions from wallboard production. He estimated that the global average of CO₂ production by wallboard was around 2.4kg/m², equating to 24Mt/yr of CO₂ for the global wallboard industry. For reference, it is estimated by the Center for International Climate and Environmental Research - Oslo (CICERO) that the process emissions from clinker production alone released around 1.6Gt/yr of CO₂ in 2022. When compared by mass (as opposed to area) to other building materials, wallboard has a lower carbon intensity than many products such as glass, cement (made from clinker), plastics, steel and plywood. Timber, concrete and brick are all better than wallboard though. However, as Bruce pointed out, a lot more concrete is manufactured than wallboard. Bruce came up with a handful of suggestions for how wallboard production could reduce its CO₂ emissions such as the reduction of slurry water, local delivery, co-generation, increasing drying efficiency and so on.

The two big sustainability trends from the sector over the last year have been the drive to support higher recycling rates of gypsum and a move towards ‘greener’ sources of energy. This can be seen in the growing use of electrical energy from renewable sources such as the production of net zero CO₂ gypsum wallboard at Saint-Gobain’s Fredrikstad plant in Norway from April 2023. The group’s Montreal plant looks set to follow in 2024 following an upgrade, potentially making it the first net zero wallboard plant in North America. Chiyoda-Ute in Japan has also started using renewably-sourced electricity at its plants in Japan, but it is uncertain what other energy sources these sites are using. China-based BNBM also claimed in its half-year results that it had built four “nearly zero emission” gypsum board production lines in the reporting period.

Wallboard's market position in North America, Europe and elsewhere seems secure. However, it is in dynamic tension as it is both a potential replacement for more carbon intensive building materials and it could also be susceptible to new emerging products that can improve on its own emissions. The manufacturers of Breathaboard and Nexaboard are clearly hoping for the latter. Yet, as is often pointed out, giving more market share to wallboard from other common building materials could reduce CO₂ emissions from construction massively. The diversification of traditional heavy building materials companies such as Holcim into light building materials in recent years suggests that some businesses are seriously preparing for this possibility. No doubt, if global wallboard usage does start to rise significantly, the pressure will grow to make wallboard more sustainable and to devise even more alternative board products.

US: Data from the United States Geological Survey (USGS) show that the sale of gypsum board products fell by 5% to 1.25Bnm² in the first half of 2023, from 1.31Bnm² in the same period in 2022. The total supply of crude gypsum grew by 9% to 20.4Mt. Notably, supplies of imported and synthetic gypsum increased in the reporting period. However, the USGS noted that on a quarterly basis “...variances are often the result of differences in weather conditions, which can impede or encourage construction activities, coupled with market demands that are often driven by residential and commercial building activity. Use of uncalcined gypsum remained stable, but consumption of calcined gypsum fell by 33% to 7.86Mt, due to reduced utilisation in board products. Spain, Canada and Mexico remained the main sources of import of crude gypsum. However, imports from Türkiye more than doubled to 195,000t.

Canada: Gypsum industry veteran Bob Bruce has died at the age of 72.

Bob Bruce worked in the gypsum sector for over 40 years. He obtained a PhD in chemistry from McMaster University in the 1970s and then worked for various gypsum companies, including BPB, in North America and Europe. He later became a consultant in the late 1990s when he founded Innogyps, before setting up NuGyp Corp in 2008. Bob Bruce was well-known as an author, speaker and mentor. He attended and spoke at many Global Gypsum Conferences over the years, and had many contacts and friends around the world. He was the Global Gypsum Personality of the Year in 2007.

Bruce's family will hold a celebration of his life in Toronto, Ontario on 28 July 2023, and have invited donations to the Joseph Brant Hospital Foundation, the CAMH Foundation and the Canadian Cancer Society in lieu of flowers. Online condolences can be made here.

US: The US gypsum wallboard industry produced 623Mm² of gypsum wallboard during the first quarter of 2023, down by 1% year-on-year and by 1.2% quarter-on-quarter. The industry exported 20.1Mm² of gypsum wallboard in the quarter under review, corresponding to 19% year-on-year growth. Canada received 19Mm² of the product, 94% of total exports for the quarter.

United States Geological Survey (USGS) data show 4% year-on-year growth in US gypsum wallboard imports. The country imported 23Mm² during the year, 20.9Mm² (91%) of it from Mexico and 1.84Mm² (8%) from Canada. Total calcined gypsum consumption was 4.66Mt in the US in the first quarter of 2023, up by 9.9% year-on-year from 4.24Mt in the first quarter of 2022.

Canada: USG Corporation subsidiary Canadian Gypsum Company (CGC) plants to restart operations at its 2Mt/yr-capacity Little Narrows gypsum quarry in Nova Scotia.

Gypsum wallboard or drywall got name-checked by the commander-in-chief of the US last week. President Joe Biden announced during his State of the Union Address to the US Congress on 7 February 2023 that he was going to require that, “all construction materials used in federal infrastructure projects to be made in America.” He then expressly mentioned wallboard along with lumber, glass and fibre-optic cables before adding the catchy sound-bite, “American roads, bridges, and American highways are going to be made with American products as well.” Although for the wallboard sector he might as well have been saying that American walls are going to be made from American wallboard.

Biden’s focus on gypsum wallboard and other building materials is linked to the US$1.2Tn Infrastructure Bill that was signed in late 2021. The White House Office of Management and Budget (OMB) issued guidance in mid-2022 on how the spending should be targeted at US manufactured construction materials. At that time it excluded steel, cement, aggregates and additives but included non-ferrous metals, plastic and polymer-based products, glass, lumber and wallboard in its category of ‘construction materials’ that should be sourced locally. Its definition of ‘construction materials’ meant that the manufacturing process for the construction material occurred in the US. Although combining some of the materials above as a composite would then be classified as a ‘manufactured product,’ at which point, 55% of the total costs of the components would have to be mined, produced or sourced in the US to meet the so-called ‘Buy America’ preference. The new bit following Biden’s recent speech is that the OMB has released further guidance for the ‘construction materials’ mentioned above. So far, so much legalese.

Canada-based manufacturers of building materials are understandably wary of this kind of talk. However, ‘Buy America’ has been around since the 1930s and there have often been ways around it. As Jean Simard, the president and chief executive officer of the Aluminium Association of Canada, told CBC, in practical terms, the math is on Canada's side. "Canada represents about 70% of total US imports. That's not going to change."

Data on how much wallboard is actually exported from Canada to the US is hard to find but the former’s wallboard sector is about 10 times smaller than the latter’s. Most of the gypsum producers in Canada are owned by international companies with a presence in the US also. This created an interesting situation in October 2022 when CertainTeed Canada welcomed the Canadian International Trade Tribunal's ruling in favour of six provinces and territories' anti-dumping measures on imports of gypsum wallboard from the US. CertainTeed is owned by France-based Saint-Gobain, which also runs Continental Building Products. Together, Saint-Gobain is the second largest wallboard producer in the US by installed capacity. It seems unlikely that the current US rhetoric will reduce Canada’s exports of crude gypsum south of the border. Data from the United States Geological Survey (USGS) shows that the US imported 1.57Mt of crude gypsum from Canada in the first nine months of 2022, an increase of 12% year-on-year from the same period in 2021. Imports from Mexico had been similar so far in 2022, although they are down compared to 2021.

The other reason Biden may have mentioned wallboard specifically in a patriotic speech may have been in relation to the long-running defective China-based wallboard story from the early 2000s. Although the legal cases associated with this have mostly died down, one popped up in early February 2023 when Knauf and its China-based subsidiaries managed to avoid a product liability claim because the Florida-based plaintiff had waited too long. Knauf now owns the US’ largest wallboard producer, USG.

It is worth remembering that the US remains the largest wallboard market in the world by production capacity. So calls by a politician to ‘Buy America’ may be more for the ears of voters rather than industry. Although that’s not to say that the situation won’t change in the future. The examples above also show that the US may have been guilty of dumping wallboard upon its neighbours and that the two largest producers in the US are both foreign owned. The other thing that Joe Biden said in his State of the Union Address was that buying American was “totally consistent with international trade rules.” This comment may have been made in response to European criticism of some of the implications of the Inflation Reduction Act with its incentives for industrial supply chains supporting renewable energy production and electric vehicles, be they based in the US or in ‘friendly’ countries. The wallboard sector seems unlikely to be caught up in this directly but protectionism is in the air. How this manifests in corporate strategy over the next few years may be telling.
