Gypsum industry news

Germany: Knauf Gips has started an upgrade at its Iphofen gypsum wallboard plant to switch its use of synthetic gypsum to natural gypsum. The project is taking place to prepare the unit for the local phase out of coal-fired power plants by 2038 at the latest. Early work at the site has involved using a 700t crane to lift material over the Würzburg-Nuremberg railway line, during planned renovation to the transport link in late July 2023. The company described the cost of the upgrade as a “mid-double-digit million sum.”

US: CertainTeed plans to invest US$235m in an expansion to its 84Mm²/yr Palatka gypsum wallboard plant in Florida. The La Tribune newspaper has reported that the Saint-Gobain subsidiary will install a second production line to double the plant’s capacity. The company will also carry out work to increase the plant’s energy efficiency.

France: Etex subsidiary Siniat plans to install a new boiler, fired by either solid recovered fuel (SRF) or waste wood, at its Auneuil gypsum wallboard plant in Oise Department. The producer expects this to reduce the plant's gas consumption by 20%. The L'Usine Nouvelle newspaper has reported that the project is part of a planned Euro30m sustainability overhaul of equipment at the plant before 2026. Siniat recently brought the Auneuil plant back online following the installation of a new Euro15m dryer in early 2023, which increased wallboard drying times by 10% and reduced gas consumption by 20%. The producer said that this has eliminated 5900t/yr of CO₂ emissions.

From the remaining Euro3m of its allotted budget for sustainability upgrades, Siniat will build a gypsum recycling plant at the Auneuil gypsum wallboard plant. It currently receives its recycled gypsum from Ritleng Revalorisations' gypsum recycling plant in Rohr, Bas-Rhin Department. Currently, natural gypsum from the Le Pin-Villeparisis and Montmorency mines accounts for 40 - 60% of the Auneuil plant' gypsum consumption.

US: Gold Bond Building Products plans to spend US$90m on an upgrade to its Mount Holly gypsum wallboard plant in North Carolina. The project will include installing a railway line and related infrastructure to aid logistics, according to the Gaston Gazette newspaper. It is expected to create 11 new jobs at the site. Construction on the project is expected to be completed in 2024. The affiliate company of National Gypsum has operated a plant at Mount Holly since 2007.

Norway: Saint-Gobain has started producing net zero CO₂ gypsum wallboard at its Fredrikstad plant. This was made possible by switching the power supply for the unit to hydroelectric power from natural gas previously. It worked with state-owned sustainable energy agency Enova on the Euro25m upgrade project. Following the completion of work at the site it will now avoid emitting 23,000t/yr of CO₂. Improved heat recovery and process efficiency will reduce energy consumption by 30%. Plus, the company says that the plant’s production capacity has been increased by 40%.

The group says that this is the world's first carbon-neutral wallboard plant and it will enable it to launch a range of products with the lowest carbon footprint on the market in 2023. It added that the this initiative was a clear indication of the company’s commitment to reduce its scope one and two CO₂ emissions by 33% by 2030 compared to 2017, with a commitment to becoming carbon neutral by 2050

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.

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.”

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.

Romania: Belgium-based Etex invested Euro1m on upgrades to the logistics capacities of its Turceni gypsum wallboard plant and its Aghiresu plaster plant. It also started work on a Euro6m sludge drying unit at coal-fired power plant in Oltenia that will supply synthetic gypsum for use at Turceni, according to See News. The company operates locally under the Siniat Romania brand. It reported a 20% year-on-year rise in turnover to Euro59.6m in 2021.
