Kiilto Ventures has made an investment in Vateris, a UK‑based advanced materials technology company that turns waste and CO2 into lower cost, lower emission, yet higher performance concrete. Vateris, formerly known as Concrete4Change, is a leader in the decarbonisation of cement and concrete with its ground-breaking technology.
The funding round brings Vateris’ total capital raised to USD 10 million. The investment marks a significant milestone in the company’s transition from pilot validation to industrial-scale deployment.
Approximately 4 billion tonnes of cement are produced annually which creates 3 billion tonnes of CO2 per year, accounting for 8% of global CO2 emissions.
“Vateris’ carbon‑to‑materials platform has the potential to reshape construction value chains and their environmental impact. This investment aligns with Kiilto’s long-term ambition to advance sustainable and high-performance solutions for the construction industry”, says Matti Rönkkö, Managing Director of Kiilto Ventures.
Vateris has developed a proprietary process that converts industrial flue gas CO₂ into GypCarb™, a high‑performance mineral additive for cement and concrete. The process also co‑produces a high‑purity mineral fertiliser, embedding permanent carbon storage and high quality into industrial products.
GypCarb™ is a drop‑in solution for cementitious systems, requiring no redesign of existing production infrastructure or changes to regulatory standards. The technology delivers improved performance, lower costs and reduced carbon intensity, supporting faster market adoption at scale.
“The science has reached maturity and the economics are compelling. With strategic industrial investors now aligned with our vision, we are moving decisively from validation to scale. Vateris is not a solely single-product company — we are building a carbon-to-materials platform”, says prof. Sid Pourfalah, Founder & CEO of Vateris.
Following the successful commissioning of its pilot plant, Vateris is now progressing towards its first commercial-scale facility, co‑located with an industrial partner and directly utilising flue gas CO2 as a feedstock.
