Quantifying Resource Inaccessibility: A Novel Metric for Sustainable Design
A new method quantifies the 'Contribution to Inaccessibility' (CTI) of resources across their lifecycle, providing a value-based metric to identify environmental hotspots and inform sustainable design decisions.
Resources Conservation and Recycling · 2023
Key Findings
- 01A novel 'Contribution to Inaccessibility' (CTI) metric was developed to quantify the impact of resource depletion and loss of accessibility.
- 02The method identified significant inaccessibility hotspots, such as resource loss in landfills and tailings deposits.
- 03Process efficiencies and circular economy strategies were shown to be critical in mitigating resource inaccessibility.
Application
Design takeaway
Incorporate a 'Contribution to Inaccessibility' assessment into the design process to evaluate how material choices and end-of-life scenarios affect the long-term availability and value of resources.
How to apply
When selecting materials, consider not just their initial cost and performance, but also their potential for inaccessibility through disposal or inefficient processing. Explore design strategies that facilitate material recovery and reuse.
Project actions
- 01Consider how your design choices might make materials difficult to access or recover after use.
- 02Research the lifecycle stages where materials are most likely to be lost or degraded.
Method & Evidence
Variables
Strengths & Limitations
Strengths
- +Introduces a novel, value-based metric for resource impact.
- +Provides a comprehensive lifecycle perspective on resource accessibility.
Limitations
Quantifying 'inaccessibility' can be complex and may require making assumptions about future resource availability and market values.
Reliability & validity
The reliability of the CTI metric depends on the accuracy of the input data (e.g., resource prices, process efficiencies) and the consistency of the defined life cycle stages. Validity is supported by its ability to identify known environmental hotspots and its alignment with circular economy principles.
Think critically
How might the 'value' assigned to a resource influence its perceived inaccessibility, and what are the ethical considerations of such valuations?
Design Principles
"Design for resource accessibility by minimizing waste, maximizing recovery, and optimizing process efficiencies throughout the product lifecycle."
Understanding how design and production choices impact resource accessibility is crucial for developing truly sustainable products. This metric moves beyond simple material quantity to assess the economic and environmental cost of making resources unavailable for future use.
What This Means for Your Design
This study found a new way to measure how 'lost' or 'hard to get' resources are due to how we make and use things. It helps us see where we're wasting resources the most and how recycling can help.
How to use in your project
- 1.Use the concept of 'Contribution to Inaccessibility' to justify design choices that prioritize resource recovery and minimize waste.
- 2.Refer to this method when discussing the environmental impact of material selection and end-of-life considerations in your design project.

Paragraph starter
This research introduces a 'Contribution to Inaccessibility' (CTI) metric, which quantifies the impact of human activities on resource accessibility across a product's lifecycle. By considering factors such as waste disposal and process inefficiencies, CTI provides a value-based assessment of resource loss, highlighting the importance of circular economy principles and efficient resource management in sustainable design.
