Rare earth elements (REE) are a crucial component in the manufacturing of various technologies that are essential for low-carbon energy and transportation systems. However, these elements are rare and finite, which poses a challenge for their long-term supply. That’s where circular economy strategies come in. A recent study published in Nature Geoscience reveals that these strategies could significantly boost the low-carbon global transition and ensure that REEs last longer.

Understanding the Role of Circular Economy Strategies

Circular economy strategies, such as reduction, substitution, reuse, and recycling, have gained attention as potential solutions to address supply chain issues for REEs. These strategies aim to reshape global supply chains by increasing the secondary supply of REEs and reducing demand. The study presents an integrated model that quantifies how circular economy strategies can achieve these goals.

The Impact of Circular Economy Strategies

According to the analysis, implementing circular economy strategies could lead to an increase of 701 kt secondary supply and a decrease of 2,306 kt demand for REEs within the next three decades. This means that we can rely less on mining REEs and instead focus on utilizing urban mines and recycling to meet our supply needs. The study also highlights the potential for regions like the EU to achieve a closed-loop REE supply with the implementation of circular economy strategies.

Addressing Supply and Demand Challenges

The study reveals a significant mismatch between in-ground stocks, supply, and demand at specific region and element levels. This mismatch, especially for heavy rare earth elements, poses a challenge in achieving net-zero emission targets. By implementing circular economy strategies, we can address these challenges and create a more balanced supply and demand landscape for REEs.

The Geopolitical Dynamics and Climate Goals

The researchers also emphasize the geopolitical dynamics and climate goals associated with REEs. As the demand for REEs grows, there is a risk of political tensions and competition over these valuable resources. Understanding the potential of circular economy strategies can help us navigate these dynamics and ensure a just low-carbon transition.

International Cooperation and the Future

The findings of this study can serve as a scientific basis for international cooperation in promoting circular economy strategies for REEs. By working together, we can maximize the benefits of these strategies and create a sustainable supply chain for REEs. This is crucial for achieving our climate goals and transitioning to a low-carbon future.

In conclusion, circular economy strategies have the potential to reshape global supply chains of rare earth elements and ensure their long-term availability. By reducing demand, increasing secondary supply, and implementing recycling and reuse practices, we can maximize the benefits of these valuable resources. Through international cooperation and a focus on sustainability, we can pave the way for a greener and more sustainable future.

Circular economy
A circular economy (also referred to as circularity or CE) is a model of resource production and consumption in any economy that involves sharing, leasing, reusing, repairing, refurbishing, and recycling existing materials and products for as long as possible. The concept aims to tackle global challenges such as climate change,...
