Gypsum industry news

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.

China: BNBM’s operating revenue grew by 2.4% year-on-year to US$1.50bn in the first half of 2022 from US$1.46bn in the same period in 2021. Its net profit fell by 11% to US$237m from US$266m. Parent company CNBM reported that its sales volumes of gypsum wallboard fell by 5.8% to 1.09Bnm² from 1.16Bnm2. It said that continued coronavirus lockdowns and problems in the real estate market had affected market demand. It added that the price of raw materials and energy had also risen, leading to increased production costs and mounting product prices.

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.

New Zealand: Winstone Wallboards says that the allocation model it introduced in July 2022 and other measures it has taken are starting to ease a shortage in gypsum wallboard. The company’s general manger David Thomas said that by operating both of its wallboard plants continuously and an upgrade to its Auckland plant in July 2022 had increased its production capacity. It has also been able to resume importing wallboard from Australia. The company is currently despatching around 3.25Mm²/month of gypsum wallboard.

The company said that is going to reduce merchant lead time between order placement and delivery from October 2022 in order to improve the effectiveness of its allocation system. It hopes that doing this will provide more flexibility along the supply chain for end-users to secure product when it is needed for installation. It also asked tradespeople to continue communicating with merchants about requirements and timings in order for the wallboard producer to understand real demand levels.

Thomas said, “The team and I recognise the responsibility Winstone Wallboards has in supplying plasterboard to the New Zealand market and want to assure you we are committed to living up to that responsibility. That we have retained such a role is not just an outcome of what we do but, a result of the high level of support the market has provided us over decades.”

Switzerland/UK: Sika says it plans to complete its planned acquisition of MBCC Group in the first half of 2023 following the decision by the UK Competition and Markets Authority (CMA) to further investigate the merger. Previously the construction chemicals company intended to close the transaction by the end of 2022. Sika signed a deal to buy MBCC Group, formerly BASF Construction Chemicals, in November 2021.

Thomas Hasler, the chief executive officer of Sika, said "Sika has already received unconditional regulatory approval across a number of jurisdictions, including Japan, China, Brazil, South Africa, Saudi Arabia, Turkey and Thailand. For a transaction of this magnitude a detailed analysis is not unusual. The adapted timeline for the closing does not impact the strategic attractiveness of the transaction. It remains highly accretive, and our expectation that it will generate annual synergies of Euro160m - 185m is unchanged."
