Eurogypsum added its views on the European Union’s (EU) proposed Critical Raw Materials Act (CRMA) last month. It wants gypsum to be added to the bill’s list of critical and strategic raw materials. It is not surprising that the European federation of national associations of producers of gypsum products might want to do this. However, when compared to rare earth minerals of the sort required to manufacture batteries for electric vehicles (EV), gypsum doesn’t seem all that, well, rare.

What may be rare though is people’s patience with new gypsum mines. The association’s argument is that gypsum is indeed abundant in the EU but that accessing it is increasingly becoming difficult. The EU’s sustainability agenda has made the energy efficiency of buildings as important as reducing CO₂ emissions from the transportation sector. Gypsum and other materials used to make lightweight building materials are a way of renovating existing buildings and improving energy efficiency. Therefore it suggests that the act should either recognise gypsum as strategic or introduce a new ‘essential’ category. This would then make the process of extracting gypsum more easy.

This approach ties back to initiatives such as one by the Federal Commission on Geosciences (BLA-GEO) in Germany, which previously started to compile an inventory of the nation’s gypsum deposits with the intention of putting this in front of policy makers. Nor is the gypsum sector alone in targeting the potentially lucrative retrofit market. In May 2023 Daikin, Danfoss, Knauf Insulation, Rockwool, Saint-Gobain, Signify and Velux signed an agreement to promote building energy efficiency in Central and Eastern Europe (CEE). Radek Bedrna, Knauf Insulation’s managing director for Eastern Europe and Middle East, noted that two thirds of the 43.6m homes in single- and multi-family houses in the CEE region were reportedly built before 1989 and are energy inefficient. The European Commission places transport-related greenhouse gas emissions at about 25% of the region’s total. Renovating buildings fully, by contrast, could save up to 5% of the EU’s emissions. Targeting transport emissions may be a higher priority for the EU but the savings from retrofitting are not trivial either.

Then - on cue in mid-June 2023 - there was an example of the difficulties gypsum product producers can face with building new quarries or enlarging old ones when expansion plans for a gypsum quarry supporting Placoplatre’s wallboard plant in Chambéry in France were scaled back from local opposition. The subsidiary of Saint-Gobain met similar issues in late 2022 when a public enquiry started examining its plans to build a new quarry at Fort Vaujours, Seine-Saint-Denis. This site is intended to serve the Vaujours gypsum wallboard plant as a replacement for its Bernouille quarry after the latter closes in 2026. This one has a happier ending, for the gypsum sector at least, since the project received an environmental permit in late May 2023. One of the key issues that came up in the enquiry was a disagreement over the means of extraction. A local environmental group favoured underground mining but an open-cast approach was preferred by the producer as it would yield much more gypsum. The latter was eventually approved.

What this suggests is that making gypsum an ‘essential’ raw material in Europe requires engagement with the general public as much as legislators. Some people may not like having a wind farm built near where they live but the chances are that there will be less opposition than building a new coal mine. Digging up new gypsum deposits should be presented as more like the former than the latter. Whizzing around in a new EV is generally seen as being more fun than bragging about how great the lamba factor is for one’s house. However, this may change if energy prices keep ticking upwards. Gypsum may not be rare but Eurogypsum and others can make a strong case for it being essential.

Two news stories to note over the last two months indicate growth in the gypsum wallboard market in Romania. Firstly, Knauf announced plans in mid-October 2022 to build a new 30Mm²/yr gypsum wallboard plant at Huedin in Cluj County. Then, Germany-based Grenzebach’s local subsidiary revealed that it had broken ground on the construction of an upgrade to its Iasi production centre.

Knauf’s announcement follows work by the existing wallboard producers with plants in the country to increase their own local capacity. Saint-Gobain started building a new production line at its Turda plant in mid-2021 at a cost of Euro45m. It hopes to have the project completed by April 2023. Etex started work in mid-2022 on a Euro6m sludge drying unit at a coal-fired power plant in Oltenia that will supply synthetic gypsum for use at its Turceni plant. It is also working on logistics upgrades to Turceni and a separate plaster plant at Aghiresu.

An indication of Saint-Gobain’s interest in the Romanian market can be seen in its universal registration document for 2021 where it outlined its strategy. It presented a graph of forecast growth rates in construction markets in selected developing markets between 2020 and 2030. The countries that are underlined in Graph 1 (above) are those where Saint-Gobain made large acquisitions or investments in 2021. Romania is interesting on this graph because it is the European country with the largest predicted growth rate. It also has a relatively low market volume suggesting potential for market growth, although note that the graph only shows selected countries.

Another reason why Knauf might be interested in Romania is that it is the largest country in the European Union in which the company does not have a wallboard plant. Knauf’s own take from its press release about why it decided to build a plant in Romania was that local per capita consumption of gypsum wallboard was around 3m²/yr compared to at least 6m²/yr in more mature markets elsewhere in Europe.

Etex’s subsidiary Siniat Romania reported a 20% year-on-year rise in turnover to Euro60m in 2021. This compares to a 24% rise in turnover to Euro307m by Saint-Gobain Romania. Andrei Popa, Etex’s Country Sales Manager Romania & SEE, told Agenda Constructiilor that Siniat Romania’s turnover grew by 25% year-on-year in the first eight months of 2022. However, it is unclear what difference Etex Group’s acquisition of insulation producer URSA in June 2022 made to the figures in Romania. Popa also revealed that the rise in turnover so far in 2022 was mainly down to price rises. This in turn had been promoted by mounting energy costs, particularly gas. The company described itself as a ‘big consumer of gas’ and reported that the price had risen seven times over the past year. One more point of interest to mention is that Popa described Etex as one of the largest exporters in the country, with 40% of local production sent over national borders. This also aligns with what Knauf said about its new plant. It intends to deliver half of the production from its proposed plant at Huedin to Hungary, Serbia and the Republic of Moldova. The other half will serve the domestic market in the north of Romania with imports from Bulgaria expected to continue to supply the south of the country.

The data above suggests why Saint-Gobain, Etex and Knauf have all invested in wallboard production units in Romania over the last two years. The local market has growth potential and the companies are also focused on exports to neighbouring countries. All this investment may also have contributed to Grenzebach’s decision to enlarge its production site at Iasi too. The ‘fly in the ointment’ here in the short term is the disruption to energy markets caused by the war in Ukraine. Siniat Romania mentioned its concern over gas prices above. Saint-Gobain also made similar comments on a general basis for Europe in its nine month financial results in late October 2022. It said that it was preparing continuity plans for its gas-consuming plants in Europe but added that its gypsum wallboard production lines were ‘extremely flexible.’ However, Romania is better prepared for problems with gas supplies compared to elsewhere in Europe because it produces around 90% of its requirements locally. Despite energy concerns at the moment, the long term potential for the wallboard market in Romania remains promising.

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.

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.
