Gypsum industry news

Canada: Leading global gypsum recycling company New West Gypsum Recycling announced the death of its founder and chief executive officer Tony McCamley on 16 March 2023. It said that McCamley will be 'deeply and dearly' missed as a proud Irishman and for his sense of humour and love of his family.

The company said "Tony was an innovator and a visionary; he was passionate about his business and his family. He started New West Gypsum Recycling over 35 years ago and it has grown into a global business with a lasting environmental impact. His success is attributed to his hard work and dedication: his legacy will live on."

Belgium: Etex's sales were Euro3.74bn in 2022, up by 25% year-on-year from 2021 levels. Its building performance division, which includes gypsum wallboard, recorded revenues of Euro2.43m, 65% of the group total. Etex said that the division’s market positions and results 'evolved positively,' and 'demonstrated leadership' in the face of raw materials price rises. The group's recurring earnings before interest, taxation, depreciation and amortisation (REBITDA) totalled Euro645m, up by 13%.

During the year, Etex's Romania-based subsidiary Siniat commissioned its new Euro1m gypsum drying and micronisation plant at its Aghiresu gypsum wallboard plant in Cluj. The market yielded turnover growth of 17% year-on-year for Siniat, to Euro72.5m

Etex recycled 54% more gypsum than in 2018 across its operations, making it 'the most advanced gypsum recycler in Europe,' according to the company. Its absolute CO₂ emissions fell by 20% over the same period.

Lithuania: Eco Baltia plans to invest Euro700,000 in the establishment of a new construction waste sorting line in Lithuania. Nordic Daily News has reported that this will enable the company to improve its material recovery rate to 82% from 60%. Supplier Ecoservice will supply the automated line, which can handle waste gypsum wallboard alongside other materials.

Eco Baltia's head of environmental management Jānis Aizbalts said "Considering the increasing volume of construction waste and the need to ensure their reuse, we are purposefully developing construction waste sorting possibilities and new technological solutions. Ecoservice has already completed a modernisation project for the existing construction waste sorting area, installing new and more efficient equipment that will double the company's construction waste sorting capacity."

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.

US: The city council of Glenwood Springs in Colorado is aiming to implement single-haul refuse collection in order to eliminate the dumping of recyclables by 2023, local press has reported. A review of waste management practices found that the city has a recycling contamination rate of just 8%, yet 80% of waste sent to landfill consists of recyclable materials. Eagle County Recycle operates the city's waste management facility. The company says that it supplies waste cardboard for gypsum wallboard backing production in neighbouring Oklahoma.

Manager Jesse Masten said “The mill in Oklahoma that we send the cardboard to actually makes the paper backing for wallboard. Then, that paper backing is potentially sent back to the American Gypsum gypsum wallboard plant in Gypsum and used for the wallboard that they’re producing.”

US: Saint-Gobain subsidiary CertainTeed's Buchanan gypsum wallboard plant in New York has successfully participated in a gypsum wallboard recycling pilot. Together with contractors Structure Tone and Cooper Recycling, it processed 20t of gypsum from waste wallboard in its gypsum wallboard production.

CertainTeed interior products vice president and general manager Jay Bachmann said "For us to achieve our sustainability goals, we must change the way we think. By partnering with organisations in the community like Cooper Recycling and Structure Tone, we can get there faster." Bachmann continued, "As the only gypsum manufacturing plant in New York, our colleagues in Buchanan were able to create a true circular economy. From the creation of drywall products to construction, to processing scraps and back into drywall production, the material is continuously used and never leaves the state. This maximises our company's positive impact while working to minimise our environmental footprint. Our Buchanan plant has increased our capacity to reuse recycled material, and we look forward to growing this successful pilot into a long-term programme, while working with builders and recyclers across the state. Partnering with CertainTeed, New York builders have the opportunity to not only reduce waste at their job sites, but also gain Leadership in Energy and Environmental Design (LEED) points on their projects."

The Buchanan plant joins CertainTeed's units at Nashville in Arkansas and Palatka in Florida in supporting the company's circular economic efforts in the US. The Nashville plant commissioned a 65,000t/yr line in May 2022, while the Palatka plant increased the recycled content of its wallboard by 18,000t/yr in August 2022. The Palatka plant plans to install a new 100t/hr Rotochopper grinding unit to replace its existing trommel machine in its reclaim processing and screening operations.

Belgium: Etex has launched its new Road to Sustainability 2030 circularity and decarbonisation strategy. The strategy sets out the company’s 2030 ambitions under five headings. Under health, safety and well-being, Etex aims to reach zero fatalities, burnouts or incidents of harm; under customer engagement, it aims to build a sustainable roadmap for each product platform by 2025; under diversity, equity and inclusion, it will extend its policies, procedures and practices across all teams. Meanwhile, under decarbonisation, Etex will reduce Scope 1 and 2 greenhouse gas emissions by 35% compared to 2018, and under circularity it will use over 20% of circular input as raw material, send zero waste to landfill, use 100% recycled packaging and reduce plastic packaging by 20% compared to 2018, offer a product take-back service across 80% of its European markets and dedicate 50% of its innovation resources to sustainability.

Chief executive officer Bernard Delvaux said “Today Etex has sustainability as a guiding compass of business transformation, with concrete objectives that reflect the company’s ambition. We are on an exciting journey towards improving sustainability in the short and long term. We know there is a long road ahead, which is why we invite all our stakeholders to further support us in becoming a leading benchmark in our industry.”

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.

Japan: Chiyoda Ute has reported that it has produced 100% climate neutral and 100% recycled wallboard at its Yokkaichi factory in Mie Prefecture. The company says that, to the best of its knowledge, this is a world first. The board was produced on 1 August 2022.

Speaking about the achievement, Frederick Knauf, Chiyoda Ute’s representative managing director said “We do not know whether another manufacturer has achieved this already on an industrial scale, but it shouldn't matter who was first, as the whole industry needs to come to this point. Being second, third or 25th is the same achievement from my point of view."
