Bristol-based Adaptavate has secured £2.7m in pre-Series A funding round, which included participation from Skreenhouse Ventures, SigmaRoc’s product innovation platform.
The collaboration between Adaptavate and SigmaRoc brings together a leading lime producer and a pioneering technology developer with the objective of transforming the low-carbon wallboard industry.
The partnership aims to establish a supply chain for calcium carbonate-based wallboards, with a shared commitment to exploring the production and distribution of Adaptavate’s products throughout Europe.
Adaptavate and SigmaRoc have signed a memorandum of understanding to collaborate on Project Crystal – an industrial demonstrator facility that Adaptavate is planning.
Adaptavate produces Breathaboard, an alternative to traditional gypsum plasterboard, made from lime and food crop by-products including oil seed rape and hemp, sandwiched between two layers of recycled paper. It is used and installed in exactly the same way as standard wallboard.
Breathaboard was developed by Tom Robinson, managing director and founder of Adaptavate, while a student at the Centre for Alternative Technologies (CAT) in Wales in 2014. The product was developed and originally tested as his MSc thesis.
Robinson said: “Over the past decade, we have developed an industrial process to manufacture construction materials that are circular, regenerative and carbon absorbing. Now, our agreement with SigmaRoc is a key milestone in our mission to scale this technology widely. SigmaRoc brings deep industrial expertise and a leading decarbonisation strategy—which will be of great help on our path to global impact.”
SigmaRoc chief innovation officer Fons Vermorken said: ‘We are proud to support Adaptavate in its mission to transform the built environment through circular, low-carbon construction solutions. Together, we are driving the next wave of sustainable construction. By leveraging SigmaRoc’s position as a leading limestone player in Europe, we bring industrial strength, infrastructure, and market reach to help scale Adaptavate’s innovations globally.
“Over the past year, their flagship product, Breathaboard, reached key milestones – meeting international wallboard standards and undergoing trials on major commercial projects with partners such as British Land, Royal London Asset Management, and Overbury. With the ability to reduce up to 4kg of CO? per square metre, Breathaboard represents a pivotal step toward healthier, more sustainable building practices. Project Crystal is set to deliver an industrial demonstrator facility and lay the foundation for global scalability.”
