Gypsum industry news

Austria: Saint-Gobain Austria, waste management company Saubermacher and construction firm PORR have secured permission to build a new gypsum-to-gypsum recycling plant in Stockerau. The plant will cost Euro7m. Saint-Gobain Austria said that the facility will support the government’s Raw Materials 2030 circular economic development plan.

CEO Peter Giffinger said "Gypsum is endlessly recyclable, but special quality criteria must be met in order for recycled gypsum to be used again to produce new panels.”

Kyrgyzstan: Representatives of Germany-based Knauf have discussed plans to build a gypsum plant in the country. Knauf General Partner Uwe Knotzer said that the company is preparing to build a plant in the northern Chüy Region, according to the Central Asian News Service. However, it is also considering constructing a plant in the southern Osh Region. As part of the meeting a memorandum of understanding and cooperation was signed between the National Investment Agency under the President of the Kyrgyz Republic and Knauf.

Mexico: Panel Rey’s El Carmen gypsum wallboard plant near Monterrey has been awarded a clean industry certification by the Federal Attorney for Environmental Protection (PROFEPA). The acknowledgement recognises that the plant operates in full compliance with legal regulations at the federal, state and municipal level. It also demonstrates environmental performance, shows a voluntary commitment to the protection and conservation of the environment and includes social responsibility awareness. The certificate has a duration of two years and will last until 2025.

Grenzebach said earlier this month that it is going to invest around Euro2m on growing its presence in Pune. The current sales and service branch will be merged with a new production site in the city in Maharashtra. The site will be used for the assembly of conveyor equipment and welding work for dryers and lehr ovens for the glass industry. Production at the new unit is expected to start in October 2023 and it will create around 30 new jobs.

The decision by the Germany-based equipment supplier to expand in India follows Saint-Gobain’s expansion plans in India. It said in late 2022 that it was planning to spend US$215m towards capacity expansion plans in 2023 as part of a larger investment in the region, of US$970m between 2022 and 2025. Its stated aim for the new investment is to grow its revenue to US$4.4bn in 2032 from US$1.5bn in 2022. To break this down, half of the group’s turnover in India comes at present from glass-related businesses, 30% from gypsum and construction chemicals and the rest from abrasives, ceramics and life sciences. Some examples of this planned investment include the acquisition by Saint-Gobain of Rockwool India, a stone wool manufacturer, in February 2023 and an agreement to buy UP Twiga Fiberglass, a glass wool producer. Saint-Gobain is the biggest gypsum wallboard producer by capacity in India with four plants, followed by USGKnauf, which runs two plants, and various independent producers.

Growing the wallboard market in India has long seemed like an enticing prospect given the country’s demographics, low production capacity per capita compared to Europe and North America, and sustainability trends. However, despite all of this, it is taking a long time to get there. One commentator on LinkedIn has suggested that this may be down to reticence from the construction sector to adopt the product. In his view wallboard in India has mainly been used for ceilings and for commercial and industrial applications but not for residential projects. Producers, such as Saint-Gobain are likely to be well aware of this. So it is interesting to note that two projects in India picked up awards in Saint-Gobain’s International Gypsum Trophy in 2023.

On the crude gypsum side, data from the Indian Bureau of Mines and the United States Geological Survey (USGS) show that India produced an estimated 4.3Mt of gypsum from its mines from reserves of 37Mt. These reserves are far smaller than other countries with large populations such as China, the US, Brazil or Türkiye. The country also produced an estimated 2.1Mt of flue gas desulfurisation (FGD) gypsum in the 2023 – 2023 financial year. However, the Cement Manufacturers Association (CMA) estimates that its sector used 13 – 17Mt in 2020 – 2021 when cement production was 331Mt and that this is forecast to rise to 20 – 25Mt in 2024 – 2025 when cement production reaches 491Mt. This corresponds to the 4 – 5% of gypsum that it is added to clinker when grinding it to manufacture ordinary Portland cement (OPC) and other cement types.

In acknowledgment of this gap between mining and usage, the Department for Promotion of Industry and Internal Trade (DPIIT) started promoting recycling gypsum from fertiliser production and power plants in May 2023. So far, its main focus has been on improving access to phosphogypsum stockpiles, although the target for FGD production is an ambitious 9.9Mt by 2025 – 2026. Unsurprisingly, gypsum exporters have benefitted from this situation. Oman, reportedly, exported nearly 5Mt of gypsum to India in 2022. Historically, Thailand and Iran have also supplied the Indian market with gypsum.

India remains the great maybe for wallboard adoption outside of North America and Europe. The latest round of investment by Saint-Gobain and Grenzebach may yet deliver on this. Both companies are looking at a range of light materials including glass and insulation not just wallboard. So far though, the main merger and acquisition activity by Saint-Gobain has been targeted on insulation companies. Once or if Saint-Gobain or anyone else starts buying gypsum companies or building new plants then we will have a sense that something is changing. Alongside this, the DPIIT’s plans to recycle more gypsum may help bring further attention to the local gypsum sector.

Spain: The government has established a Euro450m funding line for gas-intensive industries that struggled with high gas prices during 2022. The Boletín Oficial del Estado newspaper has reported that the gypsum industry is among those included. Companies can draw on up to Euro4m in relief. For those which recorded a drop of 30% or greater in earnings before interest, taxation, depreciation and amortisation, relief of up to Euro25m is available.

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.

Kazakhstan: Germany-based Knauf has signed a deal with the government of the Zhambyl region to build a gypsum wallboard and dry building mixtures plant. The project has a cost of around Euro30m, according to InterFax. Completion is scheduled by 2026. Local subsidiary Knauf Gips Taraz is now developing design and estimate documentation for the construction of necessary infrastructure. Products from the proposed plant will be sold in the domestic market. The project is one of nine agreements between organisations from Germany and Kazakhstan announced during an official visit by German President Frank-Walter Steinmeier.

US: Fertiliser company Mosaic is seeking approval from the Environmental Protection Agency (EPA) to test using phosphogypsum on a pilot road project at its New Wales site in Mulberry, Florida. It hopes to test using the substance in three 60m sections of road, according to correspondence seen by the Tampa Bay Times newspaper. The proposed test road will use a mixture of sand with up to 50% phosphogypsum in a 25cm base. The road will then be monitored over the next 18 months.

The EPA originally approved the limited use of phosphogypsum in road construction in 2020. However, this was then subsequently blocked. Local legislation in Florida allowing the Florida Department of Transportation to study the use of phosphogypsum in road construction has been approved by the Florida Senate and House of Representatives but is yet to be signed off by Governor Ron DeSantis.

The Florida Industrial and Phosphate Research Institute estimates that around 1Bnt of phosphogypsum is stored in over 20 sites in the state. Over 25Mt/yr of phosphogypsum is generated, typically from fertiliser production. Environmental groups in the state have opposed Mosaic’s proposed use of phosphogypsum in road building due to its higher level of radioactivity compared to other forms of gypsum.

Bosnia & Herzegovina: The shareholders assembly of state-owned power company RiTE Ugljevik has approved the signing of contracts for the sale of gypsum and coal with Beijing New Building Materials (BNBM) Ugljevik. The project intends to build a 40Mm²/yr gypsum wallboard plant and it has a budget of Euro50m, according to the Sarajevo Times. RiTE Ugljevik previously agreed to supply 250,000t/yr of flue gas desulfurisation (FGD) to the proposed wallboard plant.

US: CertainTeed Gypsum has received the 2023 Better Project Award from the Department of Energy for the company’s smart energy management system at its Buchanan wallboard plant in New York state. The system at the plant, which was designed in-house and consists of over 180 energy meters, allows the staff to track and contextualise energy data, forecast future energy use and tackle actual losses once identified. Within the first three months of installation, the system helped identify several opportunities to reduce energy usage and enabled the plant team to scope process changes and projects to address them. The subsidiary of Saint-Gobain now plans to deploy similar technology at sites throughout North America.

Jay Bachmann, Vice President and General Manager of CertainTeed’s Interior Product Group, said “In a dynamic, continuous production facility like our Buchanan plant, it is essential to have real-time, in-depth data that can help us reduce our energy consumption, and our smart energy management system does just that.” He thanked workers at the Buchanan plant for their efforts.

The Better Project awards recognise manufacturers who improve energy efficiency and competitiveness in the industrial sector. To be considered for an award, projects must deliver significant waste or energy savings and must be discreet, innovative, and replicable in similar industrial facilities.
