IRIS · 2012

Key Findings

01Dynamic material flow models can effectively represent the temporal evolution of resource stocks and flows.
02Analysis of resource metabolism in a region highlights key areas for improving resource efficiency and sustainability.
03Space life support systems offer a simplified 'laboratory' for studying closed-loop resource management principles applicable to terrestrial systems.

Application

Design takeaway

Integrate dynamic material flow modelling into the design process to proactively address resource constraints and design for long-term sustainability.

How to apply

When designing products or systems, consider mapping out the entire lifecycle of materials, not just their initial use, to identify potential bottlenecks or opportunities for resource recovery.

Project actions

01When researching materials for your design project, consider not just their properties but also their origin, how they are processed, and their end-of-life potential.
02Think about the 'flow' of materials in your design – where do they come from, how are they used, and where do they go after use?

Method & Evidence

AimHow can dynamic material flow analysis be used to model the evolution of resource stocks and flows to inform sustainable resource management in regional and specialized systems?

MethodDynamic Material Flow Analysis

ProcedureConstructed dynamic material flow models to simulate the evolution of specific resource stocks and flows (e.g., copper, phosphorus, wood) over several decades within a defined region, and evaluated the resource use sustainability of different space life support systems.

ContextRegional metabolism and space life support systems

Variables

IV["Type of resource (e.g., metal, nutrient, renewable)","System type (regional vs. closed-loop life support)"]

DV["Evolution of resource stocks over time","Material flow rates","Indicators of resource sustainability"]

CV["Time period of analysis","Geographical boundaries (for regional studies)","System boundaries (for life support studies)"]

Strengths & Limitations

Strengths

+Provides a dynamic, time-based perspective on resource use, moving beyond static analyses.
+Applicable to diverse contexts, from large-scale regional economies to highly controlled engineered systems.

Limitations

Gathering precise data on material flows for a specific product or region can be challenging and may require making informed estimations.

Reliability & validity

The reliability and validity of dynamic material flow models are heavily dependent on the accuracy and completeness of the input data. Sensitivity analyses can be performed to assess the impact of data uncertainties on the model's outputs.

Think critically

How might the 'peaking' of certain natural resources, even if controversial, influence design decisions and innovation strategies for products intended for long-term use?

Design Principles

"Design for resource longevity and circularity by understanding and modelling material flows over time."

Understanding how resources are used, stored, and potentially depleted over time is fundamental for designing products and systems that minimize environmental impact. This dynamic perspective allows designers to anticipate future resource availability and to develop strategies for more efficient and circular resource utilization.

What This Means for Your Design

Imagine tracking how much metal is used in phones each year and where it goes. This study shows how to do that over many years to see if we'll run out of certain metals and how to use them better.

How to use in your project

1.Use dynamic material flow concepts to justify material choices based on long-term availability and environmental impact.
2.Incorporate a discussion on resource metabolism and circularity as part of your design's lifecycle assessment.

Paragraph starter

The dynamic modelling of material flows, as explored in studies of regional metabolism, offers a critical lens for understanding resource use over time. By analysing the stocks and flows of key materials, designers can gain foresight into potential resource limitations and develop strategies for more sustainable material selection and product lifecycle management, aligning with principles of circularity and responsible resource stewardship.
