Balancing Rare Earth Element Supply and Demand Through Strategic Application Diversification

Journal of Sustainable Metallurgy · 2018

Key Findings

01Market demand for REEs in magnets, catalysts, and alloys is increasing, while demand in polishing agents, glass, and ceramics is stable.
02Demand for REEs in NiMH batteries and lamp phosphors is decreasing, creating a need for recycling and reuse in other applications.
03Magnesium and aluminum alloys present opportunities to mitigate the Balance Problem by utilizing recycled REEs.
04The criticality of specific REEs is influenced by their balance with market demand and availability.

Application

Design takeaway

How to apply

When specifying materials for a design project, investigate the current and projected market trends for critical elements like rare earths. Explore opportunities to incorporate recycled content or design for easier disassembly and material recovery.

Project actions

01When choosing materials for your design project, research their market availability and potential for future scarcity.
02Consider how your design can contribute to a circular economy by using recycled materials or designing for easy disassembly and recycling.

Method & Evidence

AimHow can the 'Balance Problem' in rare earth element markets be addressed through strategic application diversification and the development of new uses for oversupplied elements?

MethodLiterature Review and Market Trend Analysis

ProcedureThe research analyzes trends in rare earth element applications across various sectors, including magnets, catalysts, alloys, polishing agents, glass, ceramics, batteries, and phosphors. It examines how shifts in demand for specific rare earth elements impact market balance and explores opportunities for recycling and substitution, particularly in magnesium and aluminum alloys.

ContextRare Earth Element (REE) markets and their supply chain dynamics.

Variables

IVShifts in demand for specific rare earth elements across different applications.

DVThe 'Balance Problem' (surpluses or shortages) of rare earth elements.

CVNatural abundance of rare earth elements, existing recycling infrastructure, technological advancements in substitution.

Strengths & Limitations

Strengths

+Provides a clear overview of REE market trends and their implications.
+Identifies specific opportunities for mitigating the Balance Problem through recycling and alloy development.

Limitations

The paper's focus is on specific rare earth elements; your design project might involve materials not covered here. Market predictions can change rapidly.

Reliability & validity

The findings are based on an analysis of existing market data and trends, which are subject to interpretation and future uncertainty. The study's validity relies on the accuracy of the reported market data and the authors' forecasting.

Think critically

How might geopolitical factors, beyond market demand and supply, influence the 'Balance Problem' for rare earth elements?

Design Principles

"Design for Material Lifecycle Management: Consider the availability, demand, and recyclability of critical materials throughout the product's lifecycle."

This approach is crucial for ensuring the long-term viability of industries reliant on rare earth elements. By understanding market trends and the lifecycle of these materials, designers can mitigate supply chain risks and contribute to more sustainable resource utilization.

What This Means for Your Design

The supply of rare earth metals can be tricky because sometimes there's too much of one kind and not enough of another. To fix this, we need to find new things to use the extra metals for and find replacements for the ones that are hard to get or very popular.
