Anaerobic digestion of livestock manure is one of the most promising approach for producing biogas, because of it allows also to reuse the obtained solid fraction of biodigestate in agriculture as soil amendment, being this organic biomass rich in nitrogen. Effectively, the direct application to soil of animal manure can go in conflict with the Directive 91/676/CEE on the “water protection from nitrates”, especially in vulnerable zones, such as those of Northern Italy. The objective...
