Application
Design takeaway
Prioritize the design of products with circularity in mind, focusing on material recovery and reuse, particularly for critical metals like cobalt, to support the transition to sustainable energy technologies and ensure supply chain stability.
How to apply
When designing products that use cobalt, such as batteries, investigate the material's origin, consider its end-of-life scenario, and explore opportunities for recycling or remanufacturing.
Project actions
- 01When researching materials for your design project, consider their entire lifecycle, not just their initial use.
- 02Investigate the supply chains of critical materials and identify potential risks or opportunities for more sustainable sourcing.

Variables
Strengths & Limitations
Strengths
- +Comprehensive analysis of material flow over a significant time period.
- +Detailed examination of various stages of the material lifecycle and trade dynamics.
Limitations
The availability and accuracy of data for material flow analysis can be challenging. It's important to acknowledge any data gaps or assumptions made in your own research.
Reliability & validity
The study's reliability is supported by the use of a established method (Dynamic Material Flow Analysis) and a clear time frame. Validity is enhanced by examining multiple facets of material flow (consumption, production, stock, trade).
Think critically
How might the increasing demand for cobalt in EV batteries impact global supply chains and potentially lead to new geopolitical dependencies or resource conflicts?
Design Principles
"Design for circularity by integrating material lifecycle management and supply chain resilience into product development."
Understanding the lifecycle and trade dynamics of critical materials like cobalt is essential for sustainable design and resource security. This insight highlights the evolving demands and the importance of closed-loop systems in supporting green technologies.
What This Means for Your Design
This study shows how Japan uses cobalt, a metal important for batteries. It used to be mostly for phones and laptops, but now it's increasingly for electric cars. Recycling is very important, and if done well, Japan could meet its own cobalt needs. The country is importing more cobalt from China and exporting finished products to the US and Europe.
How to use in your project
- 1.Reference this study when discussing the lifecycle assessment of materials used in your design, particularly for electronic or automotive components.
- 2.Use the findings to justify your material choices or to highlight the importance of considering end-of-life scenarios for your product.
