01

Key Findings

  • 01Ingredient sourcing, particularly the use of fishmeal and fish oil, contributes significantly to the overall environmental burden.
  • 02Energy consumption during feed processing and transportation also plays a notable role in the environmental footprint.
  • 03Eutrophication potential is a key impact category driven by nutrient releases throughout the feed production chain.
02

Application

Design takeaway

Designers and engineers should actively seek to reduce the reliance on traditional, high-impact ingredients in aquaculture feeds and explore innovative, eco-friendlier alternatives and production methods.

How to apply

When designing new aquaculture feeds or improving existing ones, conduct a preliminary LCA to identify key environmental hotspots and guide material selection and process design.

Project actions

  • 01When researching materials for your design, consider their entire life cycle impact, not just their immediate properties.
  • 02Think about how your design's production and end-of-life stages affect the environment.
03

Method & Evidence

AimTo quantify the environmental impacts associated with the production of salmonid feeds throughout their entire life cycle.
MethodLife Cycle Assessment (LCA)
ProcedureThe study involved defining the system boundaries for salmonid feed production, collecting data on inputs (e.g., raw materials, energy) and outputs (e.g., emissions, waste) at each stage, and then evaluating the environmental impacts using established LCA methodologies.
ContextAquaculture feed production for salmonid species.

Variables

IV["Type of ingredients used (e.g., fishmeal vs. plant-based proteins)","Energy sources for processing","Transportation distances"]
DV["Eutrophication potential","Global warming potential","Resource depletion"]
CV["Species of salmonid","Production scale","Geographical location of production"]

Strengths & Limitations

Strengths

  • +Comprehensive analysis covering the entire life cycle.
  • +Application of a recognized environmental assessment methodology (LCA).

Limitations

Conducting a full LCA can be complex and data-intensive. For a design project, a simplified assessment focusing on key impact areas might be more feasible.

Reliability & validity

The reliability of LCA studies depends heavily on the quality and completeness of the data used. Validity is enhanced by adhering to established LCA standards and guidelines.

Think critically

How might the environmental impacts of aquaculture feed production differ in regions with varying resource availability and energy infrastructures?

05

Design Principles

"Adopt a cradle-to-grave (or cradle-to-cradle) perspective when evaluating the environmental performance of any product, especially those within complex supply chains like aquaculture."

Understanding the full environmental cost of aquaculture feed is crucial for developing more sustainable aquaculture practices. This holistic view allows designers and engineers to identify hotspots for improvement, such as ingredient sourcing or manufacturing processes, leading to reduced ecological strain.

06

What This Means for Your Design

Making fish food for salmon has a big effect on the environment, especially because of the ingredients used and how it's made. We need to find better ways to make it.
