Failing to account for a product's end-of-life condition can lead to design choices that undermine circular economy goals. This sustainability research insight is drawn from a 2023 study published in Journal of Cleaner Production. Using Modelling and simulation, researchers explored how this design variable affects real-world outcomes. The key design takeaway: Incorporate end-of-life status predictions into your design for disassembly process to ensure that circularity goals are truly met.

Key Findings
- 01Current design for disassembly methods do not adequately consider the impact of a product's end-of-life status.
- 02The 'Parent-Action-Child' model can effectively describe and quantify these impacts.
- 03Ignoring end-of-life status can result in suboptimal design recommendations for circularity.
Application
Design takeaway
Incorporate end-of-life status predictions into your design for disassembly process to ensure that circularity goals are truly met.
How to apply
When designing a product for circularity, create scenarios for its potential end-of-life states (e.g., damaged, worn, partially functional) and evaluate how your disassembly strategy performs under each.
Project actions
- 01Consider how your product might be damaged or degraded over its lifespan and how that affects disassembly.
- 02Think about different pathways for end-of-life, not just one ideal scenario.
Method & Evidence
Variables
Strengths & Limitations
Strengths
- +Introduces a novel model for evaluating end-of-life impacts.
- +Provides a quantitative approach to assess circularity in relation to end-of-life status.
Limitations
It can be difficult to accurately predict all possible end-of-life scenarios for a product.
Reliability & validity
The study's validity is supported by the development of a novel model and its application to a specific case. Reliability would be enhanced by testing the model across a wider range of product types and end-of-life scenarios.
Think critically
To what extent can designers realistically predict and design for all possible end-of-life scenarios, and what are the trade-offs involved?
Design Principles
"Design for disassembly must be adaptive to the variable conditions of a product's end-of-life."
Effective circular design requires anticipating how a product will be handled and processed at the end of its useful life. This insight emphasizes the need for design strategies that are adaptable to various end-of-life scenarios, ensuring that disassembly efforts and material recovery are optimized for true circularity.
What This Means for Your Design
When you design something to be recycled or reused, you need to think about what condition it will be in when it's time to do that. If you don't, your recycling plan might not work as well as you hoped.
How to use in your project
- 1.Use the concept of end-of-life status to justify design choices aimed at improving disassembly and material recovery.
- 2.Discuss how your design accounts for potential variations in product condition at end-of-life.

Paragraph starter
The design for disassembly strategy for this project has been developed with consideration for the product's potential end-of-life status. Recognizing that products may not always reach their end-of-life in pristine condition, design choices have been made to ensure effective disassembly and material recovery even under varied states of wear or minor damage, thereby enhancing the product's contribution to a circular economy.
