When developing new products or processes, use software or develop frameworks that allow for the simultaneous evaluation of environmental footprint, cost, and efficiency. Prioritize design choices that minimize negative environmental externalities without compromising essential functionality or economic viability.

Project actions

01When choosing materials or processes for your design, research their environmental impact using tools like LCA databases.
02Try to quantify the environmental benefits of your design choices, not just the functional or aesthetic ones.

Method & Evidence

AimHow can Life Cycle Assessment be integrated into thermo-economic models to enable multi-objective optimization for sustainable process design?

MethodModel Integration and Simulation

ProcedureThe study developed a methodology to link Life Cycle Inventory (LCI) data with a thermo-economic model. Environmental indicators derived from Life Cycle Impact Assessment (LCIA) were expressed as functions of process design parameters. This integrated model was then used to optimize the production of synthetic natural gas (SNG) from woody biomass, considering environmental, economic, and thermodynamic objectives.

ContextEnergy conversion system design, specifically synthetic natural gas production from biomass.

Variables

IVIntegration of LCA into thermo-economic models.

DVMulti-objective optimization outcomes (environmental, economic, thermodynamic performance).

CVSpecific process parameters (e.g., feedstock type, conversion technology, scale).

Strengths & Limitations

Strengths

+Provides a quantitative methodology for integrating environmental factors into design.
+Demonstrates a practical application in a relevant industrial context (energy production).

Limitations

Performing a full LCA can be time-consuming and require specialized software. Simplifying the LCA for a student design project might be necessary.

Reliability & validity

The reliability of the findings depends on the accuracy of the input data for both the LCA and the thermo-economic model. Validity is enhanced by the direct application to a specific process optimization problem.

Think critically

To what extent can simplified LCA methods provide sufficient data for meaningful multi-objective optimization in a design project?

Design Principles

"Holistic optimization requires the integration of environmental, economic, and performance metrics."

This approach moves beyond purely economic or efficiency-driven design by quantifying and integrating environmental impacts. It enables designers to make more informed decisions that balance resource utilization, emissions, and overall system viability, leading to more holistically sustainable solutions.

What This Means for Your Design

You can make better designs by looking at how much they cost, how well they work, AND how much they harm the environment, all at the same time.
