Gypsum industry news

UK: The Pallet LOOP says that the first batch of its RFID-tagged reusable pallets has entered the UK construction supply chain. This follows its delivery of 30,000 of the pallets to British Gypsum’s Barrow, East Leake and Kirkby Thore gypsum wallboard and plaster plants earlier in May 2024, in partnership with Scott Pallets.

The Pallet LOOP CEO Paul Lewis said "If your business hasn’t already signed up for LOOP collections, now is the time to do so. Our distinctive green reusable pallets are now winging their way across the country, and we want recipients to be ready to send them back to us."

The Pallet LOOP will collect, inspect, repair and redistribute the pallets, paying registered return partners up to €4.69 for each pallet returned.

UK: The Pallet Loop has concluded a strategic agreement to provide its pallets collection service for British Gypsum’s UK distribution operations. From May 2024, British Gypsum will deliver bagged plaster using The Pallet Loop’s green pallets. It will subsequently begin to transition its gypsum wallboard distribution to The Pallet Loop pallets from July 2024, resulting in 70% coverage of its entire distribution of products. The subsidiary of Saint-Gobain plans to eventually raise this to 100%.

British Gypsum managing director Dean O’Sullivan said “We are delighted to announce our partnership with The Pallet Loop as we aim to radically cut unnecessary waste. Pallets left behind after products have been removed have for a long time created a challenge, with many being unsustainably disposed of at a heavy environmental cost. By joining forces with The Pallet Loop, we aim to significantly reduce this practice.”

The Pallet Loop managing director Paul Lewis said “At Loop, our mission is to transform the way building materials move and we are incredibly excited that British Gypsum, as a market leader, is partnering with us to promote a culture of pallet reuse. Using our service, merchants, distributors, principal contractors and housebuilding companies will be able to book pallet collections, which can take place from as little as 72 hours later. There will also be a payback of up to €4.69 available for every green coloured pallet they put back in the loop.”

UK: Adaptavate has inaugurated its first pilot line to produce Breathaboard bio-based alternative wallboard. Breathaboard performs in the same way as ordinary gypsum wallboard, but sequesters and avoids additional CO₂ emissions, reducing the board’s total carbon footprint by 4kg/m². Adaptavate's production process uses fibrous and cellulosic by-products from agricultural crops, combined with minerals. It has a minimal water footprint and does not require natural gas.

Chief technical officer Jeff Ive said "The commissioning of our pilot line is the culmination of a year's hard work. We knew the solution had to be scalable for significant impact. With full-size boards produced on a continuously extruded process, we’re turning our vision into reality. This pilot line is a game changer for us, our industry, and the planet, laying the foundation for global replication of our core innovation."

UK: Saint-Gobain subsidiary British Gypsum has launched its BIMlocker software, a tool to enhance the use of its building information modelling (BIM) objects. The company says that BIMlocker improves customers’ data accuracy and accountability. The tool integrates with existing Revit software.

Head of digital construction Paul French said "Demonstrating compliance, accountability and integrity has never been more important within our industry. Our new BIMlocker software provides reassurance as an invisible layer of security that acts as a valuable aid to construction supply chains in the Building Safety Act era. It eliminates any ambiguity and ensures complete transparency."

UK: Knauf UK and Ireland has announced the launch of a new gypsum wallboard recycling service in partnership with waste management company Encore Environment. The partners will trial the service at contractor Manchester Design and Build’s renovation of the Piccadilly Warehouse in Manchester.

Knauf UK and Ireland national client development manager Jon Watts said “The existing Sittingbourne recycling plant and service is fantastic. However, with this partnership we’re able to really tap into on-site recycling and ensure as much goes back into the supply chain as possible. This is critical, as we don’t want plasterboard being transported all over the country. It’s broken down locally and then gets distributed back to plasterboard manufacturers.”

UK: British Gypsum’s non-loadbearing metal stud plasterboard partition systems, including shaft walls, have become one of the first products on the local market to carry the Code for Construction Product Information (CCPI) mark. The scheme is intended to provide assurance to end users that the product information for these products is clear, accurate, accessible, up-to-date and unambiguous.

The CCPI was initiated by the Construction Product Association (CPA) as a direct response to Judith Hackitt’s review of Building Regulations and Fire Safety set up in the wake of the Grenfell Tower fire in 2017. The CPA is a UK-based construction industry trade association.

Ireland/UK: Belgium-based Etex has appointed Oliver Cripps as its Head of Sustainability, UK and ireland to support its brands, including Siniat. His role will be to push the company’s sustainability agenda, heighten the environmental credentials of its operations and products and decrease reliance on raw materials.

Cripps has worked for 25 years in the sustainability sector in industries including tourism, land management and manufacturing. His previous jobs include Senior Sustainability Manager at Dyson Technology, where he led sustainability for the New Product Innovation and Research teams, and experience working with global furniture manufacturer, MillerKnoll to support research and development and corporate sustainability.

UK: British Gypsum’s Robertsbridge plant has celebrated the 150th anniversary of the discovery of gypsum at the site in East Sussex. To mark the event the company held a family day with a range of activities, according to the Sussex Express newspaper. Tanya Young, the plant manager, said "Our legacy is grounded in this discovery, and it's incredible to see how gypsum remains an essential component in modern construction, proving its enduring value over the years." She added “The majority of our employees are locals, and we're proud to have generations of families who have been a part of the British Gypsum family for decades."

Belgium: Etex’s Building Performance division drove revenue in the first half of 2023 through price rises despite a softening in gypsum wallboard sales volumes. The group’s total revenue grew by 4% year-on-year on a like-for-like basis to Euro2.02bn in the first half of 2023 from Euro1.79bn in the same period 2022. Its earnings before interest, taxation, depreciation and amortisation (EBITDA) rose by 14% to Euro363m from Euro319m in real terms.

Bernard Delvaux, the chief executive officer of Etex, said “In the first half of 2023, Etex coped with an overall slowdown of the construction sector - both in new build and renovation - triggered by several elements leading to high volatility and uncertainty such as inflation that puts pressure on consumers’ buying power, higher interest rates and more restricted loan policies by banks. However, Etex managed to record improved sales compared to the first half of 2022 through swift adaptations to challenging market contexts and cost-to-price monitoring. While our volumes are slightly impacted, margins remain strong.”

Notable events so far in 2023 include Etex’s acquisition of UK-based Superglass Insulation in June 2023. It divested its two Russia-based units under its Ursa subsidiary in August 2023. It also acquired Betacon, a Romania-based company to secure raw material supply for wallboard activities in the country.

One can tell that gypsum wallboard is a popular product because companies keep trying to devise alternatives to it. A recent one is Breathaboard. The company making it, Adaptavate, announced in August 2023 that it had generated around Euro2.3m in its latest investment round. It is building a pilot production line in Bristol in the UK and attempting to licence its Breathaboard product, amongst other plans. Its take on wallboard is being marketed as a sustainable substitute that is made from crop waste, that sequesters CO₂ and that then can be composted at the end of its life. It is also promoting the product’s breathability and moisture buffering capabilities, hence the name.

Another new contender hoping to steal some of the gypsum wallboard market is Xeriant’s Nexaboard product. This one uses plastic waste as its alternative to gypsum. Florida-based Xeriant said in July 2023 that it had started to buy equipment and raw materials, was running pilot production and was testing its first samples. It too is working on getting its product used in pilot construction projects.

Both of these examples, and others over the years, have taken a pop at wallboard’s sustainability credentials. Adaptavate is rather quieter about what happens to all of that sequestered CO₂ when its product is composted and Xeriant does not mention the environmental impact of making the plastic it uses in the first place. Yet, it is a valid question to ask how sustainable is gypsum wallboard? This column has covered issues with the supply of raw gypsum from either natural, synthetic or recycled sources previously, so we will stick to the general picture here.

The late-lamented consultant Bob Bruce pulled together data from various studies for the Global Gypsum Conference in 2019 to estimate the CO₂ emissions from wallboard production. He estimated that the global average of CO₂ production by wallboard was around 2.4kg/m², equating to 24Mt/yr of CO₂ for the global wallboard industry. For reference, it is estimated by the Center for International Climate and Environmental Research - Oslo (CICERO) that the process emissions from clinker production alone released around 1.6Gt/yr of CO₂ in 2022. When compared by mass (as opposed to area) to other building materials, wallboard has a lower carbon intensity than many products such as glass, cement (made from clinker), plastics, steel and plywood. Timber, concrete and brick are all better than wallboard though. However, as Bruce pointed out, a lot more concrete is manufactured than wallboard. Bruce came up with a handful of suggestions for how wallboard production could reduce its CO₂ emissions such as the reduction of slurry water, local delivery, co-generation, increasing drying efficiency and so on.

The two big sustainability trends from the sector over the last year have been the drive to support higher recycling rates of gypsum and a move towards ‘greener’ sources of energy. This can be seen in the growing use of electrical energy from renewable sources such as the production of net zero CO₂ gypsum wallboard at Saint-Gobain’s Fredrikstad plant in Norway from April 2023. The group’s Montreal plant looks set to follow in 2024 following an upgrade, potentially making it the first net zero wallboard plant in North America. Chiyoda-Ute in Japan has also started using renewably-sourced electricity at its plants in Japan, but it is uncertain what other energy sources these sites are using. China-based BNBM also claimed in its half-year results that it had built four “nearly zero emission” gypsum board production lines in the reporting period.

Wallboard's market position in North America, Europe and elsewhere seems secure. However, it is in dynamic tension as it is both a potential replacement for more carbon intensive building materials and it could also be susceptible to new emerging products that can improve on its own emissions. The manufacturers of Breathaboard and Nexaboard are clearly hoping for the latter. Yet, as is often pointed out, giving more market share to wallboard from other common building materials could reduce CO₂ emissions from construction massively. The diversification of traditional heavy building materials companies such as Holcim into light building materials in recent years suggests that some businesses are seriously preparing for this possibility. No doubt, if global wallboard usage does start to rise significantly, the pressure will grow to make wallboard more sustainable and to devise even more alternative board products.
