The BATTSi (Valorization of Industrial Waste Streams for Battery Grade Silicon) project addresses a critical challenge in the battery industry: how to meet the rising demand for high-purity silicon without relying on environmentally intensive production methods. Coordinated by Centria University of Applied Sciences, this international effort brings together research institutions, SMEs, and industrial partners from Finland, Iceland, Ireland, and Sweden to transform silicon-rich industrial by-products, such as brewers’ grain husks and geothermal geosilica, into valuable anode materials for lithium-ion batteries. By focusing on circular resource use, BATTSi supports the green transition, reduces reliance on virgin raw materials, and fosters innovation-driven growth in Northern Europe.

The University of Eastern Finland (UEF) contributes its expertise in silicon recovery and battery material development, working alongside key academic partners including the University of Iceland, the University of Limerick, and Luleå University of Technology. The project also benefits from strong industry engagement with associated partners like Terrafame, Anora Group, and HS Orka, providing real-world piloting environments. MACON Ltd leads the commercialization strategy and stakeholder engagement. BATTSi’s outputs—technical guidelines, policy briefs, and training resources—will be disseminated to industry and public authorities, helping integrate circular economy principles into battery production. With a €1.53 million budget (65% ERDF co-funded), the project runs from 2024 to 2027 and directly contributes to the European Green Deal, Finland’s Battery Strategy, and the UN Sustainable Development Goals.
