Anaerobic Co-Digestion of Chicken Manure - Effect of Material Relations in Feed Mixture and Hygienisation on Biogas Production

S. Luste & H. Soininen
Anaerobic digestion of chicken manure (CM) is challenging due to the high nitrogen content of the material. Co¬digestion of CM with cattle slurry (CS) and vegetable wastes (VW) from a food industry dilutes the feed material and enhances the buffering capasity towards the pH increase. Anaerobic co¬digestion of CM, CS and VW from a food industry was studied in the wet weight (W.W.) relations of A) 10:70:20 (hygienised mixture A*; 70 °C/1 hour), B) 13:76:11,...
