Researchers at Swedish universities are examining the potential for domestic rare earth element production as a means to support cleaner manufacturing processes and reduce global supply chain vulnerabilities. The work focuses on leveraging Sweden’s known mineral deposits in locations including Kiruna, Bergslagen, and Norra Kärr to create an alternative to predominantly China-based production of rare earth magnets and related materials.
Martin Sahlberg, a materials chemistry professor, noted that geopolitical tensions have underscored the risks of concentrated supply chains, pointing to recent trade disputes and export restrictions as examples of how supply disruptions could affect industries dependent on rare earth materials. Current production methods also carry substantial environmental costs, involving toxic chemicals and exposure to radioactive substances during the separation and purification phases. The current concentrated manufacturing landscape means that environmental and industrial standards vary significantly across production locations.
The research initiative aims to develop a novel approach to magnet manufacturing by designing products whose composition matches the naturally occurring elemental mixtures found in Swedish deposits, rather than forcing locally sourced materials into existing manufacturing formulas. This strategy could reduce processing requirements and lower the overall environmental footprint of production. Sweden’s advantages for this effort include access to water resources, relatively affordable energy, and demonstrated interest in advancing green industrial practices.
The interdisciplinary research effort, which combines expertise from materials physicists, geologists, and engineers, will take several years to complete. An initial priority involves comprehensively cataloging the rare earth minerals available throughout Sweden and determining their concentrations and proportions across different deposits. The team plans to develop new magnet formulations tailored to available resources, optimizing the use of all extracted materials rather than targeting single valuable elements as in traditional mining approaches.
The project represents application-inspired basic research that connects fundamental scientific inquiry to technologies with significant implications for Sweden’s economic transition and broader global efforts toward sustainable manufacturing.
