A groundbreaking study, recently published in the prestigious journal Nature Geoscience, unveils a new integrated model showing the transformative impact of circular economy strategies on the global rare earth elements (REE) market. This research is pivotal for industries reliant on critical REEs like neodymium, dysprosium, and terbium. The study forecasts a significant boost in REE recycling and secondary supply, projecting an increase of 701 kilotonnes and a reduction in demand by 2,306 kilotonnes over the next 30 years, reshaping the landscape of REE supply chains.

Delving into the nuances of circular economy’s role in REE supply and demand, the research identifies a stark imbalance between in-ground resources and current supply-demand dynamics across various regions. This disparity is particularly pronounced in the supply of heavy rare earth elements, a crucial factor in achieving net-zero emission goals.

The study’s findings are a game-changer for the REE sector, suggesting that strategies such as substitution, reuse, and recycling could revolutionize the way REEs are sourced globally. Specifically, the increased reliance on urban mining for REE supply, as forecasted in this study, could drastically reduce the dependency on traditional mining practices. The European Union, in particular, stands to benefit significantly, potentially achieving a self-sustaining cycle in REE supply through the adoption of circular economy methods.

Professor Oliver Heidrich, a co-author of the study from Newcastle University, highlights the comprehensive nature of their model. It considers both underground and in-use stocks, alongside their anticipated geographic shifts across ten regions from 2001 to 2050, under three widely recognized climate scenarios. This approach provides an in-depth understanding of the supply-demand relationship, geopolitical influences, and the strategic use of natural resources.

The implications of this study are far-reaching, offering a solid scientific basis for international collaboration in promoting circular economy strategies for REEs. Such collaboration is essential for achieving a just and low-carbon global transition.

Presently, the natural reserves of REEs are concentrated in a handful of countries, including China, Vietnam, Brazil, the United States, Russia, and the Democratic Republic of the Congo. China’s dominance, controlling over 90% of the global supply and close to 40% of the reserves, underscores the vulnerability of REE availability to geopolitical conflicts, supply chain disruptions, and price fluctuations.

This study is a critical resource for businesses, policymakers, and stakeholders in the REE sector, offering a roadmap for sustainable and resilient supply chains.
