Key Findings
- 01Most recyclers employ mechanical treatment, pyrometallurgy, or hydrometallurgy, primarily focusing on high-value metal extraction.
- 02There is an environmental and technological gap in achieving closed-loop recycling or component material reuse.
- 03The SWAVE matrix provides a quantitative score (out of 20) to rank recycling processes based on the number of materials recycled.
Application
Design takeaway
Prioritize recycling processes that maximize the recovery and value of a wider range of materials, moving beyond simple metal extraction towards closed-loop systems and component reuse.
How to apply
When evaluating or designing recycling processes for complex products like batteries, use a framework that considers the strategic value and potential for reuse of all recovered materials, not just the most valuable metals.
Project actions
- 01When researching recycling methods, look for studies that assess the full range of materials recovered, not just the primary metals.
- 02Consider developing a scoring system similar to SWAVE to evaluate different recycling options for your design project.
Method & Evidence
Variables
Strengths & Limitations
Strengths
- +Development of a novel assessment matrix (SWAVE).
- +Qualitative assessment of a large number of commercial recyclers.
Limitations
The SWAVE matrix is a qualitative tool, and its application might be subjective. The study focuses on commercial recyclers, and smaller-scale or emerging technologies might not be fully represented.
Reliability & validity
The qualitative nature of the SWAVE matrix and the assessment of recyclers may introduce subjectivity, impacting reliability. Validity is supported by the systematic application of the matrix across multiple companies and the comparison of findings with established recycling practices.
Think critically
How can the SWAVE matrix be adapted to assess the recyclability of products beyond batteries, and what additional factors might need to be considered?
Design Principles
"Maximize material value and circularity in end-of-life product management."
As the volume of end-of-life lithium-ion batteries increases, effective and sustainable recycling processes are crucial. The SWAVE matrix provides a structured method for designers and engineers to assess the efficacy of different recycling strategies, moving beyond simple metal recovery towards more comprehensive material value retention.
What This Means for Your Design
This research shows that most companies recycling old batteries just pull out the valuable metals, but they could do better by trying to reuse more parts of the battery or recycle them in a way that keeps more of the original material's value.

Paragraph starter
The research by Sommerville et al. (2020) highlights a significant gap in current lithium-ion battery recycling, where processes predominantly focus on high-value metal extraction rather than comprehensive material recovery and closed-loop recycling. Their development of the SWAVE matrix offers a valuable qualitative assessment tool to evaluate the strategic importance and value of various materials within end-of-life batteries, underscoring the need for design and recycling strategies that prioritize broader material circularity.
