Gypsum industry news

UAE: The wallboard recycling unit at Saint-Gobain Gyproc’s Abu Dhabi gypsum wallboard plant has processed 22,000t of gypsum since 2014, the L'Usine Nouvelle newspaper has reported. The producer said that the Abu Dhabi plant can incorporate 10 – 12% recycled materials in its gypsum wallboard production. It runs on a diversified energy supply, which in its most recent recorded month included 55% nuclear, 38% natural gas and 7% solar energy.

In 2023, Saint-Gobain reduced its non-recycled waste by 78% year-on-year and its water footprint by 14% from 2017 levels in the UAE.

Europe/US: Tristan Suffys, secretary general of Eurogypsum, the European gypsum association, presented the association’s net zero roadmap at the Global Gypsum Conference 2023 in Chicago, US, on 9 November 2023. Live and online audiences heard Eurogypsum’s full life cycle-based carbon footprint analysis, according to which European gypsum wallboard currently generates CO₂ emissions of 2kg/m², 14% lower than 2008 levels. On its pathway to net zero by a deadline of 2050, Eurogypsum plans to reduce wallboard’s CO₂ emissions from raw materials by 13%, from transport by 12%, from production by 69% and from end-of-life processes by 6%.

Suffys said “Presenting our roadmap today in Chicago is a clear signal that global warming requires global action. We want to engage with other regional actors along the way to climate neutrality.”

Eurogypsum president Jörg Ertle added “We are committed to making this transition a reality. First examples show that we can move towards net-zero emission production if we have access to low-carbon energy at affordable costs and optimal raw material supply, but this will require significant investment from our sector.”

US: Beneficial Reuse Management (BRM) has acquired Pennsylvania-based gypsum wallboard recycling firm USA Gypsum (USAG).

BRM board chair Dave Schuurman said “The acquisition of USAG gives BRM an opportunity to further diversify our sources of gypsum to include recycled scrap wallboard, as well as to grow our geographic footprint. USAG’s operations will complement our existing gypsum processing operations, which provide gypsum in pelletised form to agricultural and other markets. This acquisition aligns perfectly with our mission of providing sustainable solutions for the management of industrial byproducts to divert materials away from landfills.”

US: Xeriant says that it has successfully tested a high-volume production process for its Nexboard alternative wallboard. The wallboard is made of recycled plastic content, and is 100% recyclable.

Recycling Today News has reported that CEO Keith Duffy said “The industry is desperate for a viable green alternative to gypsum board as part of a transition toward greater efficiency, safety and sustainability in building design. Drywall has essentially remained unchanged for over a century and is extremely vulnerable to moisture and mold. Our homebuilder clients are anxious to receive and approve our production samples so we can execute pending contracts and begin our quest to disrupt the building materials industry.”

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."

US: Advanced materials producer Xeriant plans to enter trial production of its recycled plastic-based gypsum wallboard alternative, NEXBOARD. Plastic products company TMF Corporation will support production by agglomerating post-industrial plastic waste and densifying it, along with different eco-friendly flame retardants, for use as feedstock.

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.”

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."
