Gypsum industry news

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: Adaptavate has raised around Euro2.3m in its latest investment round. This investment round has been led by Counteract, with Low Carbon Innovation Fund 2 (LCIF2), Semin and Perivoli Innovations. It follows Adaptavate’s previous seed funding round, announced in March 2022, and subsequent support received to industrialise the development of carbon negative construction materials including developing industrial processes to make low-carbon and carbon absorbing plaster and wallboard.

The company is currently building a development centre, including laboratories and a pilot production, line in Bristol and conducting research to complete testing and licencing programmes for its Breathaboard product. Breathaboard is a gypsum-free wallboard manufactured from compostable crop waste. Adaptavate intends to start use Breathaboard produced on the new line in pilot construction projects by the end of 2023. The new funding will also be used to develop other sustainable building products. The company is additionally looking to licence its technology to the large building products manufacturers and has already started conversations with potential partners.

Tom Robinson, the chief executive officer and founder of Adaptavate, said “This funding round is a pivotal point in the acceleration of Adaptavate and our aim to be the world leader in this space. With the support of like-minded funding partners, we are leading the carbon revolution of building materials as a form of carbon capture and utilisation. What I am most pleased about is that this funding round was oversubscribed, which shows the appetite for near to market, industrially scalable carbon absorbing technologies, even at an economically challenging time.”

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.
