Biorefinery Glas

Biorefinery Glas

Biorefinery Glas focuses on the demonstration of a small-scale grass biorefinery with farmers in South West Ireland to diversify farmer produce while resolving significant challenges in traditional agriculture.

Biorefinery Glas in South West Ireland explores innovative approaches to address challenges in feedstock integration with anaerobic digestion, focusing on utilising whey nutrients as biofertilizer. Field trials have demonstrated the effectiveness of whey biofertilizer in promoting grass growth and enhancing its quality compared to traditional slurry application. The biorefinery process involves separating protein-rich liquid juice from grass, which is used to supplement pig diets, resulting in improved feed intake and weight gain while reducing reliance on imported soy feed. Additionally, the project evaluated the use of press cake silage from the biorefinery as cattle feed, showing potential for reduced emissions and improved nutrient utilisation efficiency. Ultimately, the farmer-led bioeconomy model aims to enhance overall farm efficiency by producing multiple co-products, including green protein concentrate, prebiotics for animal nutrition, and biofertilizer or biogas from residual fractions, thus contributing to sustainable agricultural practices and resource utilisation.
