Brewer's Spent Grain in Sustainable Fish Feed: Life Cycle Assessment Data

A 21.6 KB Excel file by E. Geremia, last updated March 2026, analyzes the potential of brewer's spent grain (BSG) as an alternative protein source in aquaculture feed. It compiles data on BSG's protein content (15%–27% dry matter), antinutritional factors, and environmental impacts from hypothetical diet formulations. The dataset supports research into circular economy applications for the brewing and aquaculture industries.

Use Cases

• Assessing the environmental impact of aquafeed formulations based on Life Cycle Assessment data.
• Modeling the replacement of traditional protein sources with brewer's spent grain based on its documented protein and antinutritional factor content.
• Evaluating processing strategies like hydrolysis and fermentation for improving BSG's nutritional profile for fish feed.
• Comparing the sustainability of different aquafeed ingredients within a circular economy framework.

Strengths

• Data is based on specific, quantified BSG protein content (15%–27% of dry matter).
• Includes analysis of hypothetical diets with defined BSG inclusion levels (10% and 37%).
• Released under a permissive CC-BY-4.0 license for reuse.

Limitations

• Row count and column-level documentation are unknown, limiting suitability assessment.
• The dataset is very small (21.6 KB), indicating limited scope or a summary-level analysis.
• Description metadata is limited; actual data structure and quality require manual inspection after download.
