Transforming Brewing Spent Grain into Resilient Crops and Functional Foods
Watch our short introductory video and find out how BrewSelBar is brewing sustainability from grain to glass.
Discover BrewSelBar
BrewSelBar takes a different approach by turning brewer’s spent grain into a valuable agricultural input.
Through optimised extraction and controlled selenium enrichment, the project develops a plant-based biostimulant designed to improve barley resilience under real farming conditions.
The approach is tested and validated from laboratory to field, with a focus on reliability, safety, and practical use.
By linking brewing, agriculture, and food production, BrewSelBar supports a more resource-efficient system, where by-products are put back to use and value is created across the chain.
The Solution
Europe’s brewing industry produces millions of tonnes of brewer’s spent grain (BSG) every year, a nutrient-rich material that is still largely underused.
At the same time, barley crops are under increasing pressure from drought, heat, and declining soil quality, making consistent yields harder to maintain.
Turning BSG into a practical agricultural input, such as a selenium-enriched biostimulant, is not simple. It requires careful processing, controlled enrichment, and solid validation to ensure it works reliably in real farming conditions.
