Piggery waste, effluent residues and its supernatant from an intensive farm unit equipped with a plant of biogas production were analyzed for their properties and chemical composition. Remarkable quantities of mineralizable or available nutrients were found in the effluent after anaerobic digestion. The obtained results indicate that the effluents are a better material for agriculture use as fertilizer than not digested pig excreta.
