What are the economic benefits of grass biorefineries?
Grass biorefineries provide multiple economic benefits by transforming a widely available, renewable resource—grass—into a range of high-value products. Through processes like those in the Biorefinery Glas and Grass2Algae projects, farmers can produce animal feeds, bio-based fertilisers like grass whey, and even grow protein-rich microalgae, creating new income streams. These products can replace costly imports such as soy feed and mineral fertilisers, lowering input costs. Grass whey adds further value by turning waste into usable fertiliser, reducing waste management expenses. By increasing the economic value of grass, enabling diversified product outputs, and reducing reliance on external resources, grass biorefineries empower farmers to become active players in local bioeconomies and boost profitability in a more sustainable, circular agricultural system.
