French industrial liquid purification specialist Eurodia has secured an €18 million investment to support the growing number and scale of its projects, including direct lithium extraction, refining and recycling.
Eurodia Industrie has raised €18 million from French investment firms Starquest Capital and Yotta Capital Partners to finance its international expansion and the scale-up of its industrial projects.
The investors have taken a minority stake in the company, which develops liquid extraction and purification processes for applications including direct lithium extraction (DLE), lithium refining and battery recycling.
Eurodia said its revenue increased from approximately €34 million in 2023 to €80 million in 2025 as both the number and size of its projects grew. The Pertuis-based company has installed more than 450 industrial systems in over 50 countries and generates 80% of its revenue outside France.
Founded in 1988, Eurodia designs processes for extracting, separating, purifying, concentrating and recovering materials from complex liquids. Its technologies include electrodialysis, bipolar electrodialysis, chromatography, adsorption, ion-exchange resins and membrane filtration.
Eurodia to support DLE from brines
In the lithium industry, Eurodia’s processes are intended to support DLE from brines as well as the subsequent refining and recovery of the critical battery material. Its reference projects include DLE equipment deployed at Rio Tinto’s Salar del Rincón lithium project in Argentina.
The company also supplies technology for recovering mineral co-products and reducing the consumption of water, energy and chemical reagents. Other target markets include carbon capture, biobased chemicals and the electrification of chemical processes traditionally powered by fossil fuels.
Eurodia president Mathieu Bailly said: “We are delighted to partner with Starquest Capital and Yotta Capital Partners, who share our group’s values and vision. Backing from such leading players in the eco-energy transition is a powerful endorsement. The growing number and scale of projects in this sector confirm the market’s strong momentum and fuel our ambition. This partnership will support our rapid growth while maintaining the excellence, innovation and professional approach that have earned Eurodia its reputation with clients over many years.”
Starquest Capital investment director Mathilde Andrier said: “Over the past few years, Eurodia has proven the value of its high-tech solutions in tackling key industrial decarbonisation challenges, demonstrating excellent project execution on a large scale, such as the DLE deployment at the Salar del Rincón with Rio Tinto. This partnership also illustrates how French technology can secure access to critical materials for the energy transition. We are proud to support Eurodia in this next chapter of its history.”
Yotta is investing through its Yotta Growth Industry strategy, which provides growth capital to industrial scale-ups. Both investors are using funds classified as Article 9 under the EU Sustainable Finance Disclosure Regulation, meaning they have sustainable investment objectives.
Yotta Capital Partners managing partner Vincent Deltrieu said: “Eurodia perfectly exemplifies the kind of industrial growth path we want to support at Yotta Growth Industry. The company has achieved remarkable growth and is now scaling up in deep, rapidly accelerating markets, offering solutions that directly contribute to the decarbonisation and transformation of industry. Our goal is to support Eurodia’s teams through this next phase by leveraging our experience in scaling innovative industrial businesses.”
Eurodia employs more than 100 people in France and the US. The company also supplies purification systems to the dairy, cheese, sugar and speciality sugar industries.
