Solar drying, a nature-based technology, with low environmental impact and energy cost, is being used for the first time for nutrient recovery from anaerobically digested animal manures. The final product is comparable to other organic fertilizers. In this work, a mass balance of combined digestate treatments (solid-liquid separation, stripping, acidification and solar drying) is presented to evaluate the potential of this technology, identifying its bottle-necks and feasibility at full-scale
