DIMITRA is a LIFE-funded project led by the University of Verona that develops next-generation bio-fertilisers by recovering nutrients from agricultural waste within a circular-economy framework. The project focuses on upgrading digestate — the nutrient-rich by-product of anaerobic digestion — to prevent pollution and transform it into high-quality fertilising products.
Two demonstration plants in Greece and Italy are testing advanced separation, filtration and reverse osmosis technologies to recover nitrogen, phosphorus and potassium while reducing emissions, odours and water use. The Italian pilot, installed at the La Torre farm, treats about 20 tonnes of digestate per day and produces bio-fertilisers suitable for maize cultivation.
DIMITRA shows how innovative and replicable solutions can convert waste into valuable products, support EU goals on renewable energy and circularity, and strengthen Europe’s autonomy in agricultural fertiliser production.
