Current circular economy indicators inadequately capture the unique characteristics of biobased systems, limiting their effective integration into a circular bioeconomy. This sustainability research insight is drawn from a 2023 study published in Resources Conservation and Recycling. Using Systematic literature review, researchers explored how this design variable affects real-world outcomes. The key design takeaway: When designing with biobased materials, consider developing or utilizing metrics that specifically track renewable resource share, cascading use potential, and nutrient cycle closure, as standard circularity indicators may be insufficient.

Key Findings
- 01Existing circular economy indicators primarily focus on resource flow quantities (e.g., resource use efficiency, recirculation rate).
- 02Many indicators fail to adequately incorporate essential biobased system characteristics like renewable resource share, cascading use, and organic recycling.
- 03Gaps exist in assessing the functional use of resources and preserving the quality of recycled biobased materials, which is critical for optimizing cascading use and nutrient cycle closure.
Application
Design takeaway
When designing with biobased materials, consider developing or utilizing metrics that specifically track renewable resource share, cascading use potential, and nutrient cycle closure, as standard circularity indicators may be insufficient.
How to apply
When evaluating the circularity of a biobased product design, supplement standard resource efficiency metrics with an assessment of renewable resource content, potential for cascading use across different applications, and strategies for nutrient recovery at end-of-life.
Project actions
- 01When researching biobased materials for your design project, look for studies that discuss specific metrics for their circularity.
- 02Consider how your design can enable cascading use or nutrient recovery, and think about how you might measure this.

Variables
Strengths & Limitations
Strengths
- +Provides a comprehensive overview of the current state of circularity indicators.
- +Specifically addresses the under-researched area of biobased systems within circular economy measurement.
Limitations
It can be challenging to find universally accepted or standardized metrics for biobased circularity, requiring careful justification of any chosen measurement approach.
Reliability & validity
The reliability of the review depends on the systematic methodology employed in selecting and analyzing the literature. Validity is enhanced by the focus on a specific, under-researched area (biobased systems) within a broader field.
Think critically
Given the limitations of current indicators for biobased systems, what novel metrics could be developed or adapted to better assess their circularity, and how would these impact design decisions?
Design Principles
"Prioritize the development and application of bio-specific circularity metrics to fully realize the potential of biobased resources in a circular economy."
For designers and engineers working with biobased materials, this gap means existing tools for measuring circularity are insufficient. Developing and adopting more nuanced indicators is crucial for optimizing resource use, promoting cascading applications, and ensuring nutrient cycle closure in biobased product design and lifecycle management.
What This Means for Your Design
The way we measure how 'circular' something is doesn't quite fit biobased stuff like wood or food waste yet. We need better ways to measure things like using materials multiple times or getting nutrients back.

Paragraph starter
The current landscape of circular economy indicators, while advancing, exhibits limitations when applied to biobased systems. As Vural Gürsel et al. (2023) highlight, many existing metrics focus on material flow quantities but fail to adequately address crucial biobased characteristics such as renewable resource share, cascading use, and organic recycling. This gap necessitates a more tailored approach to measuring circularity for biobased products to fully unlock their sustainable potential.
