Rare Earth Element Scarcity Threatens Technological Advancement
Category: Resource Management · Effect: Strong effect · Year: 2018
The availability of rare earth elements (REEs) is a critical bottleneck for modern technologies, necessitating research into new sources and recycling methods to ensure future supply security.
Design Takeaway
Proactively design products with material circularity in mind, considering the long-term availability and ethical sourcing of critical elements like REEs.
Why It Matters
Designers and engineers rely on a consistent supply of materials for product development and manufacturing. Understanding the criticality of REEs highlights the need to design for material longevity, recyclability, and the exploration of alternative materials to mitigate supply chain risks.
Key Finding
Rare earth elements are indispensable for modern technology, but their supply is vulnerable due to concentrated sources and the difficulty of recycling, underscoring the urgent need for innovation in sourcing and recovery.
Key Findings
- Rare earth elements are essential for numerous high-tech applications.
- Current sources are geographically concentrated, posing supply risks.
- Recycling of REEs from end-of-life products is technically challenging but crucial for sustainability.
- Further research is needed across mineralogy, extraction, and recycling to secure future supplies.

How to Apply
When selecting materials for a new design project, research the supply chain and environmental impact of critical elements. Explore opportunities to reduce reliance on scarce materials or design for easier end-of-life recovery.
Limitations
The paper focuses on the criticality and sources of REEs; specific design solutions for recycling or substitution are not detailed.
Student Guide (IB Design Technology)
Simple Explanation: Some special metals, called rare earth elements, are needed for phones and computers. We don't have many places to get them from, and it's hard to recycle them. This means we might run out, so we need to find new ways to get them or reuse them.
Why This Matters: Understanding the scarcity of materials like rare earth elements is crucial for designing products that are sustainable and won't become obsolete due to lack of components.
Critical Thinking: How might the geopolitical landscape influence the availability and cost of rare earth elements, and what design strategies could mitigate these risks?
IA-Ready Paragraph: The criticality of rare earth elements (REEs) presents a significant challenge for modern technological design, as highlighted by research indicating concentrated sources and difficulties in recycling (Jowitt, 2018). This underscores the importance of considering material lifecycle and supply chain resilience during the design process, potentially leading to the exploration of alternative materials or the implementation of design-for-disassembly strategies to facilitate material recovery and reduce future dependency on scarce resources.
Project Tips
- When choosing materials for your design project, think about where they come from and if they are hard to get.
- Consider how your product can be taken apart at the end of its life so materials can be reused.
How to Use in IA
- Reference this research when discussing the material selection phase of your design project, particularly if your design relies on elements with known supply chain issues or environmental concerns.
Examiner Tips
- Demonstrate an awareness of the global supply chain and material criticality when justifying material choices in your design project.
