Grass can be used to produce additional products like animal feed, prebiotics, bioenergy, and fertilizers

The Biorefinery Glas project demonstrated and evaluated a small-scale grass biorefinery process with Irish farmers. ​ The project focused on improving Ireland's livestock sector's sustainability, value, and resource efficiency through farmer diversification into the bioeconomy. ​ Key activities included onboarding farmers, conducting biorefinery demonstrations, and analyzing various co-products such as press-cake cattle feed, protein concentrate pig feed, fructo-oligosaccharides, bio-fertilizer, and biogas potential. ​ The project demonstrated that grass can be used to produce additional products like animal feed, prebiotics, bioenergy, and fertilizers, offering significant economic, social, and environmental benefits.
