Gypsum industry news

US: Georgia-Pacific’s Sweetwater West gypsum wallboard plant in Texas has completed an upgrade to its board-drying equipment. It has installed an Energy Optimization System (EOS), also known as a waste heat recovery unit, including new ducting, two new fans and a new exhaust stack, to an existing four-zone dryer. The newly upgraded system enables the collection of the waste exhaust from three zones of the plant and injects it into a fourth zone. This enables the burner in that zone to operate at a lower capacity. Around 2500t/yr of CO₂ is saved in the process.

David Neal, vice president of Gypsum Operations for Georgia-Pacific said, “Advancements in energy savings and resource consumption reduction are goals toward which Georgia-Pacific works every single day.”

Georgia-Pacific started building a second wallboard plant next to its Sweetwater West plant in late 2020. The new 65Mm²/yr unit was scheduled to start production in late 2022.

Japan: Two workers have died at Chiyoda-Ute’s Yokkaichi gypsum wallboard plant in Mie Prefecture. The accident occurred when three sub-contractors were conducting regular maintenance work near a wood waste boiler at the site. Local press reports that the workers became trapped in a dust collector during the incident. Chiyoda-Ute is investigating what happened.

Tanzania: Knauf Gypsum Tanzania says that it plans to more than double the production capacity of its 15Mm²/yr gypsum wallboard plant in Mkuranga, Pwani Region, to 43Mm²/yr. IPP Media News has reported that the company's planned investment in the project as US$49.3m. The producer expects that the expanded Mkuranga gypsum wallboard plant will increase its annual gypsum wallboard exports by 170%. When commissioned in 2025, the plant will be the largest in East and Sub-Saharan Africa.

France: Saint-Gobain’s sales grew by 14.5% on a like-for-like basis to Euro38.4bn in the first nine months of 2022 compared to Euro32.9bn in the same period in 2021. Strong sales growth was reported in all business lines although sales were driven in particular by the group’s High Performance Solutions business and its Asia-Pacific and North America regions.

The group noted that raw materials, freight and energy costs were growing, especially in Europe. It said that it had hedged around 80% of its natural gas and electricity purchasing needs for 2022 and around 60% for 2023. It has also been preparing continuity plans for its gas-consuming plants in Europe to ensure the flexibility of production to operate with less or alternative energy. The group said that its gypsum wallboard and construction chemicals production lines were “extremely flexible.”

By region the group said it had started the world’s first zero-carbon wallboard production at its Balsta plant in Sweden powered by biogas and ‘green’ electricity. In France it produced and marketed its Placo Infini 13 product, which is said is the first wallboard made from over 50% recycled gypsum.

UK: British Gypsum has started converting its heavy-good vehicle fleet fuel source to the biofuel Hydrotreated Vegetable Oil (HVO) from diesel. The subsidiary of France-based Saint-Gobain expects to use 75,000l/week of HVO. This means that around 40% of its UK fleet will now operate on HVO fuel, with a further 10% using Liquefied Natural Gas (LNG). The use of multi-fuelled vehicles at this scale is expected to reduce its carbon emissions by approximately 70% year-on-year.

To support the implementation of HVO vehicles, the company has made several upgrades to site infrastructure that include a HVO refuelling point at its Robertsbridge plant and a new fuel island capable of delivering 110,000l/week at its distribution centre in Gotham.

Romania: Germany-based Knauf has announced plans for the construction of a new gypsum wallboard plant at Huedin in Cluj County. The company said that it plans to invest Euro76m in the plant’s construction. It says that the investment will advance the Romanian government's 'energy savings offensive' by supporting a renovation drive for the country’s housing stock. The government aims to increase the national area of modern renovated properties by a factor of six, with a Euro30bn allocation from its Recovery and Resilience Fund.

Knauf's managing partner Alexander Knauf said “The commitment demonstrates our trust and confidence in the country and our employees. We look forward to becoming part of the local community. Together, we are setting new standards for building and living in Romania.”

Knauf had previously planned to build a 35Mm²/yr gypsum wallboard plant at Huedin at a cost of Euro70m. A mine at nearby Aghireșu would supply the planned plant with raw materials. The Aghireșu mine reportedly has 100 years' worth of gypsum reserves. Knauf first delayed its Huedin plant plans in 2009 in light of the economic situation at that time.

India: The state government of Karnataka has approved the allotment of 6 hectares of land to Everest Industries. Reuters News has reported that the company is considering building a Rapicon reinforced aerated concrete and gypsum wallboard sandwich panel plant at the site.

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.

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.”
