Can the US and EU Break China's Grip on Rare Earths?

Key Concepts

• Rare Earths: A group of 17 chemical elements with unique properties crucial for modern technologies.
• Misconception of Rarity: Rare earths are not inherently scarce; the challenge lies in mining and refining them.
• Bottlenecks: Regional mining limitations and processing capabilities are the primary obstacles.
• Global Distribution: China holds approximately 60% of rare earth deposits and dominates processing (around 90%).
• Recycling Potential: Magnetic rare earths have the highest recycling capabilities, vital for batteries and defense applications.
• Collection Rates: Low collection rates of rare earths from electronic components are a significant bottleneck for recycling.
• Policy Focus: Policymakers are currently prioritizing recycling infrastructure over upstream supply chain development and waste collection.
• Green Transition & AI: These trends are expected to significantly increase demand for rare earths.
• IEA Data: Projections suggest recycling capacity could double by 2040, but this is a long-term solution.
• Domestic Supply Chains: Focusing on domestic processing and recycling of existing electronics (e.g., data centers, wind turbines) is a smart strategy.
• EU Funding: The EU has identified around 60 critical raw material projects, allocating approximately 500 million euros per project, covering exploration, recycling, and processing.
• Public and Private Funding: Both public and private investment are crucial for developing rare earth supply chains, as seen in the US with companies like MP Materials.

Rare Earths: Challenges in Supply and Processing

The Misconception of Rarity and Global Bottlenecks

A common misconception about rare earths is that they are scarce. However, the primary challenge is not their availability but the difficulty and cost associated with mining and refining them properly. This bottleneck exists both in terms of regional mining capabilities and, more significantly, in processing. The European Union (EU) and the United States (US) are actively seeking to enhance their efforts in these areas.

Global Distribution and Processing Dominance

Rare earth and critical materials are distributed globally. China currently holds approximately 60% of rare earth deposits. Crucially, China's dominance extends to processing, where its share of the global appetite reaches around 90%.

Recycling Potential and Limitations

Recycling rare earth and critical raw materials presents an interesting opportunity, though it is not a complete solution. Research indicates that magnetic rare earths possess the highest recycling capabilities. This is particularly positive as these materials are essential for applications like batteries and defense systems.

However, scaling up recycling capacity will take considerable time. The process of recycling rare earths is comparable in difficulty to recycling batteries, utilizing existing technologies. The key challenge is not just the technological feasibility of recycling but also the collection of these materials. Rare earths are typically found in electronic components, where collection rates are currently very low. Gathering sufficient quantities for effective recycling is a major bottleneck that policymakers have yet to adequately address.

Policy Focus and the Need for Upstream Solutions

Current policy efforts, particularly in Europe and the US, tend to focus on the downstream end of the value chain, specifically on companies with recycling capabilities and infrastructure. Significant financial support has been directed towards these areas.

However, there is a perceived gap in policy support for the upstream segment of the supply chain. This includes developing robust spent waste collection schemes and potentially implementing requirements for mandatory recycled content in electronic devices. This has created a "chicken and egg" situation where investment and policy are struggling to align.

Demand Drivers and Supply Realities

The green transition and the surge in artificial intelligence (AI) are expected to dramatically increase the demand for rare earths. In terms of supply, the current recycling rate for rare earths globally is only about 1%. This means recycling is not yet making a material difference to supply chains.

According to International Energy Agency (IEA) data, recycling capacity is projected to double by 2040. While this is a positive development, it signifies a long-term solution. In the short term, the focus needs to be on exploring alternative materials, securing broader deals, and investing in exploration and processing alongside recycling as a long-term strategy that requires consistent policy and investment.

EU and US Strategies: Competition or Collaboration?

There appears to be space for both the EU and the US to pursue their own strategies regarding rare earths. A smart approach involves recognizing that critical raw materials are embedded within electronics once they enter a market. This includes components in data centers, data center upgrades, and wind turbines. By focusing on domestic supply chains and capacity for processing and recycling these existing resources, both regions can develop sensible approaches.

Investment in Critical Raw Materials

The EU has highlighted approximately 60 projects within its broader Critical Raw Materials Act, with plans to fund each project with around 500 million euros. These projects span exploration, recycling, and processing. While a single definitive figure for the total investment is difficult to ascertain, the overall financial commitment is substantial.

Funding for these initiatives comes from both public and private sources. In the US, for example, companies like MP Materials have received funding from both the Trump administration and private investors, demonstrating a mixed approach to financing critical materials development.

Conclusion

The challenge of rare earths lies not in their scarcity but in the complex and geographically concentrated nature of their mining and processing. While recycling offers a promising long-term solution, particularly for magnetic rare earths, it is currently hampered by low collection rates and requires significant time to scale. Policymakers need to address the upstream supply chain and waste collection alongside existing efforts in recycling infrastructure. The increasing demand driven by the green transition and AI necessitates a multi-faceted approach involving exploration, processing, and robust recycling, supported by both public and private investment, to build resilient domestic supply chains.
