Product circularity can be effectively quantified by measuring the ratio of recirculated economic value to the total product value, using value chain costs as an estimator. This sustainability research insight is drawn from a 2017 study published in Journal of Industrial Ecology. Using Metric development and validation, researchers explored how this design variable affects real-world outcomes. The key design takeaway: Prioritize design choices that maximize the economic value retained within the product's lifecycle, thereby enhancing its overall circularity.

Key Findings
- 01Existing product-level circularity metrics lack standardization, hindering reliable assessment.
- 02The economic value of product parts offers a theoretically justified basis for aggregating diverse material flows into a single circularity value.
- 03A metric based on the ratio of recirculated economic value to total product value, estimated via value chain costs, can quantify product circularity.
- 04Sequential approximation of product parts and activities can protect sensitive financial data and maintain neutrality.
Application
Design takeaway
Prioritize design choices that maximize the economic value retained within the product's lifecycle, thereby enhancing its overall circularity.
How to apply
When designing new products or redesigning existing ones, map out the value chain costs associated with each component and process. Aim to minimize costs related to virgin material acquisition and end-of-life disposal, while maximizing costs associated with repair, refurbishment, and remanufacturing.
Project actions
- 01When evaluating your design, consider the cost of materials and manufacturing. Then, estimate the potential value that could be recovered through recycling, refurbishment, or resale.
- 02Use this value comparison to justify design decisions that promote longevity, repairability, or recyclability.
Method & Evidence
Variables
Strengths & Limitations
Strengths
- +Provides a unified, economically relevant metric for circularity.
- +Offers a practical method for calculation using accessible data (value chain costs).
Limitations
Gathering precise cost data for all parts of a product's value chain can be challenging for a student project.
Reliability & validity
The reliability and validity of the metric depend on the accuracy and consistency of the value chain cost data used for estimation. The sequential approximation method aims to enhance neutrality and protect sensitive data, contributing to its potential validity.
Think critically
How might the reliance on economic value as a metric inadvertently favor certain materials or manufacturing processes over others, potentially overlooking other crucial aspects of sustainability?
Design Principles
"Quantify circularity through economic value retention."
This approach provides a standardized and economically grounded method for assessing how well a product aligns with circular economy principles. By focusing on economic value, it offers a tangible and potentially more persuasive metric for businesses and stakeholders concerned with both environmental impact and financial viability.
What This Means for Your Design
Think about how much money is tied up in a product's materials and how much of that money can be recovered or reused when the product is no longer new. A higher percentage of recovered money means a more circular product.
How to use in your project
- 1.You can use this metric as a framework to analyze the circularity of your design concept, comparing it to existing products or alternative design choices.
