Valorization of Industrial Waste Streams for Battery Grade Silicon.

Programme 2021 - 2027 Interreg VI-B Northern Periphery and Arctic

Date of latest update: 2025-09-24

Description

Description (EN):

Battery value chains have recently emerged as a vital economic activity in Northern countries. The project aims to position the NPA as a leader in sustainable battery technologies, driving both economic growth and environmental sustainability in the region. The BATTSi project mobilizes transnational research groups, industry experts, and service providers to enhance innovation capacity for the valorization of locally available sustainable materials within battery material value chain. The project pilots technologies for conversion of silicon-rich side and waste streams, such as grain husks and geo-brine, into battery-grade silicon. A comprehensive technology transfer and commercialization roadmap will be developed, which will detail the specifications for these technologies, along with evaluations of scalability, techno-economic implications, environmental impacts, and key stakeholders. This roadmap will facilitate technology adoption among battery material manufacturers in the NPA.

Expected Achievements (EN):

The specific objective of the WP1 is to establish and validate a collaborative framework that integrates a set of methods and relevant infrastructure for characterizing battery-grade materials derived from industrial side streams and waste. This framework will be piloted through collaboration in mapping and analyzing the suitability of silicon-rich streams, such as grain husk and brewers' spent grain from the food and beverage industry, as well as geo-brine from geo-energy production, for use as a feedstock for anode-grade silicon material in battery manufacturing. The mapping results will be used for quantification of resource restoration and the resulting conservation of primary silicon mineral reserves. The service database for battery material characterization, including service providers and experts will be established and made accessible through the websites of each participating organization. The work package focuses on testing and piloting new technologies and processes to advance the use of silicon-rich side streams and waste as feedstock for anode-grade materials. It explores innovative solutions for cascade recovery of silicon compounds from biomass, pretreatment of geo-brine, reduction of silica to elemental silicon, purification to the required quality (A1.2), and the production of silicon-containing half-cells for battery performance testing (A1.3). The goal is to validate the technical, economic, and environmental feasibility of these technologies, addressing challenges related to energy efficiency, safe and cost-effective chemicals, and optimal silicon yield. This pilot involves collaboration between R&D teams and the battery materials industry, with insights guiding further development, commercialization potential, and advancing sustainable battery technologies on a broader context. The goal of WP3 is to facilitate the seamless transfer of technologies, foster collaboration within the battery material value chain, and ensure innovations reach and benefit relevant sectors and stakeholders. WP3 supports the communication efforts of WP1 and WP2, while also ensuring the long-term durability of project outcomes. A key deliverable of WP3 is the joint development of a Technology Transfer and Commercialization Roadmap, which provides a structured guide for actions related to the uptake of new technologies. WP3 will also organize six technology transfer workshops with industries, prepare a policy brief for regional and local development authorities, and implement broader communication measures aimed at reaching a wider audience. Regular feedback mechanisms will ensure the roadmap's effectiveness, strengthening the connections between R&D teams and industry for a more successful technology transfer.

Contribution to wider strategies and policies:

EuropeanGreenDeal BATTSi supports the European Green Deal's objective of achieving climate neutrality by 2050 by contributing to the development of sustainable battery technologies. The project's focus on recycling industrial waste into battery-grade silicon reduces the carbon footprint of battery production, aligning with the EU's climate goals. The project results greatly move ahead to achieve the target of 15% of EU annual consumption of strategic raw materials to be covered via recycled materials by 2030.
AtlanticStrategy By developing innovative technologies for extracting battery-grade silicon from industrial waste, BATTSi supports the Atlantic Action Plan 2.0's goal of unlocking the potential of the blue economy in the Atlantic area while preserving marine ecosystems and contributing to climate change adaptation and mitigation.
TerritorialAgenda2030 BATTSi contributes to the Territorial Agenda 2030's objectives of a Just Europe and a Green Europe by promoting sustainable development and innovation in the NPA region. The project's transnational approach aligns with the Agenda's emphasis on multilevel cooperation and place-based solutions.
EUStrategyBalticSeaRegion The BATTSi project aligns with the EU Strategy for the Baltic Sea Region by addressing sustainable waste management and resource efficiency. It promotes prosperity and a circular economy by converting industrial by-products into battery-grade silicon. Focusing on innovation and sustainable growth, the project fosters transnational cooperation to tackle shared environmental challenges in the Baltic Sea region.
SeaBasinStrategyArcticOcean It aligns with the EU's commitment to a sustainable and prosperous future by enhancing regional collaboration and innovation. It supports sustainable development goals through recycling, reducing reliance on raw materials, and promoting clean energy solutions. By fostering economic resilience in the NPA regions, the project addresses local needs while strengthening broader EU objectives for environmental sustainability and economic integration, ultimately contributing to a greener economy.
Other BATTSi supports Ireland's Climate Action Plan by recycling silicon waste into high-performance battery materials, reducing the need for raw material mining and lowering the carbon footprint of battery production. Aligned with the National Waste Policy 2020-2025, it transforms industrial waste, advancing sustainable resource management and circular economy goals. BATTSi also promotes Green Public Procurement by developing sustainable silicon-based batteries for future use in public procurement.
Other Fossil Free Sweden: The national strategy for a sustainable battery value chain is developed by the government initiative Fossil Free Sweden in cooperation with EIT InnoEnergy who also developed the foundation of the European Battery Strategy for the European Commission. Additionally, the Swedish strategy for a sustainable battery value chain shows how actions in Sweden will contribute to the European battery industry development.
Other UNEP SDG12:
Target 12.1: to implement the 10-year framework on sustainable consumption and production;
Target 12.2: for the sustainable management and efficient use of natural resources by 2030;
Target 12.4: environmentally sound management of chemicals/wastes throughout their life cycle;
Target 12.6: Substantially reduction of waste generation via recycling
Other Finland's Battery Strategy aims at becoming a leader in battery technology and production, the strategy emphasizes sustainable production methods, including the use of recycled materials like silicon. Also other strategies like Finland's Circular Economy Strategy, Climat Change Act, regional development strategies (e.g. Centria Ostrobothnia, North Savo, North Finland) focus on sustainable industrial ecosystems.
Other As part of its commitment to sustainability, Iceland supports the development and export of green technologies. By promoting the export of materials like geosilica as such or converted to silicon, Iceland can position itself as a leader in the green materials market.
