Adaptavate raises Euro2.3m in funding to support commercialisation of bio-based alternative wallboard
03 August 2023UK: 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.
UK: The European Space Agency, University of Glasgow and others are using France-based Saint-Gobain's Bantycock, Nottinghamshire, quarry to test new drill bit designs for their Drill for Extensive Exploration of Planetary Environments Using Robots (DEEPER) project. The project aims to develop tens-of-metres-long spoolable drill 'strings' to help in the search for water on Mars. Researchers will use their prototypes to drill directly into the mine's gypsum deposits. Saint-Gobain said that the hydrated mineral gypsum provides a similar geological profile to that of Mars.
Gypsum wallboard production by Saint-Gobain subsidiary British Gypsum at its nearby Barrow upon Soar, Leicestershire, and East Leake, Nottinghamshire, gypsum wallboard plants relies on Bantycock gypsum.
Germany: The German Gypsum Association (GIPS) has welcomed the publication of a government report that took an inventory of natural gypsum deposits. It supports the work as it allows its members to make qualified decisions about future planning. The Federal Commission on Geosciences (BLA-GEO) has created a register of gypsum supplies in the country. The association added that it believes there will be no large-scale alternatives to natural gypsum supplies in the foreseeable future. This is due to low volumes of gypsum recycling and falling production of flue gas desulfurisation (FGD) Gypsum as coal power plants are shut down.
University of Canterbury researching seaweed-based wall panel
24 January 2022New Zealand: University of Canterbury (UC) student Andy (Minhong) Park has developed a biocomposite wall panel that uses seaweed or algae as a bio-filler. Preliminary testing indicates the plasterboard-style product offers similar fire performance to other commercially available products. Using seaweed also provides moisture control properties. The finished seaweed plasterboard product has a glossy marble surface, coloured green, red or brown depending on the type of seaweed used.
“Seaweed is fast-growing at 0.5m/day and is capable of sequestering around 173Mt/yr. It’s easy to cultivate and can be farmed offshore, not competing for farmable land with other bio-based materials, making it an attractive, low-cost farming commodity. Because seaweed can absorb carbon underwater, large wall-panel manufacturers could employ seaweed farming as a carbon offset by growing it,” said Park.
The 12 week project was supervised by UC Product Design Senior Lecturer Dr Tim Huber in collaboration with UC Fire Engineering Lecturer Dr Dennis Pau. While still in the early stages of research, design and testing, the team is working with the UC’s Research and Innovation team to develop a commercialisation plan, and Kaiārahi Rangahau Māori to identify suitable species of seaweed for product development and marine agriculture. The project recently won the UC Innovation Jumpstart Greatest Commercial Potential Award and a US$13,000 prize.
UK: Adaptavate and the University of Bath have produced alternative gypsum-free wallboard from compostable crop waste. The partners have received funding from the National Biofilms Innovation Centre (NBIC) for a six-month pilot project of production of their prototype wallboard, called Breathaboard. It uses the natural properties of bacteria to form a board with similar properties to gypsum wallboard. The producers claim that it is both lighter and more insulative than gypsum wallboard. They hope to scale up production and market Breathaboard as an environmentally friendly alternative to gypsum wallboard, as it does not require gypsum extraction or flue gas desulphurisation (FGD) at coal-fired power plants.
Project leader Susanne Gebhard said “This is an exciting project that will see whether we can exploit the natural biofilm-forming abilities of bacteria to function as a kind of glue that will help improve the properties of biodegradable construction materials.”
Dalhousie University proceeds to Phase 2 of research into concrete production with waste gypsum
10 September 2021Canada: Dalhousie University, in collaboration with the Canada and US joint Gypsum Association and Divert NS, has entered Phase 2 of its research project into uses of construction and demolition waste gypsum in concrete. The research, continuing until September 2023, will test the durability of various concrete mixes containing gypsum powder recycled from waste drywall. It will examine 81 specimens under three environmental exposures and three exposure durations. The team will use the results to understand the performance and environmental benefits of concrete containing recycled gypsum over the life of a structures. Study leader and Canada research chair in sustainable infrastructure Pedram Sadeghian said that Phase 1 of the study had demonstrated that gypsum could be a viable supplementary cementing material when combined with fly ash in concrete.
Sadeghain said “Our research group aims to study the durability of concrete containing recycled gypsum by monitoring compressive strength and potential expansion after exposure to selected environmental conditions, such as moisture and salt particle penetration, that are common to concrete structures exposed to the environment.”
Gypsum Association executive director Stephen Meima said “The gypsum industry is committed to landfill diversion of construction and demolition gypsum panel waste, and Professor Sadeghian’s work demonstrates that waste gypsum panels may have value beyond their service life in buildings and homes.”
Canada: The Gypsum Association has partnered with Divert NS to support research at Dalhousie University into the use of recycled gypsum from construction waste in concrete production. Dalhousie University previously demonstrated that gypsum could be a viable supplementary cementitious material when combined with fly ash in concrete. In this second phase of research, the team aims to expand on the work to optimise concrete production methods and product quality.
Canada research chair in sustainable infrastructure Pedram Sadeghian said “As durability is important for construction materials, our research group at Dalhousie University aims to study the durability of concrete containing recycled gypsum by monitoring the compressive strength and potential expansion after exposure to selected environmental conditions such as moisture and salt particle penetration that are common for concrete structures exposed to the environment.”
Gypsum Association executive director Stephen Meima said “We are very pleased to join Divert NS in supporting research that may improve numerous environmental outcomes. The gypsum industry is committed to landfill diversion of construction and demolition gypsum panel waste, and Professor Sadeghian’s work demonstrates that waste gypsum panels may have value beyond their service life in buildings and homes.”
UK: British Gypsum’s mine at Brightling near Robertsbridge has provided gypsum samples to researchers from the Natural History Museum. The rock specimens are intended to aid the scientists in looking at signs of past life in preparation for a joint European Space Agency and Russian Roscosmos State Corporation mission to send a robotic rover to mars in July 2020, according to the Rye & Battle Observer newspaper. Previously, NASA's Mars Rover Opportunity found bright veins of a mineral, which appeared to be gypsum, in 2011.
"Minerals like those found at Brightling hide clues within them that can tell us about the history of liquid water where they formed, and they have the potential to trap and preserve organic material. Studying these natural fresh samples on Earth that mimic not just the minerals, but also the formation environments we see on Mars, will give us an insight into the potential for life to be detectable at the ExoMars2020 landing site," said Louisa Preston, UK Space Agency Aurora Research Fellow and member of the Department of Earth Sciences at the Natural History Museum.
