ANAEROBIC DIGESTION AND CO-DIGESTION OF POULTRY LITTER SUBMITTED TO DIFFERENT REUSES

ABSTRACT Considering the constant increase in the waste generation from poultry and pigs’ husbandries, the main contributions of this study were to verify the potential of biogas production through the anaerobic digestion and co-digestion of the residues generated by these two activities, as well as to highlight the recovery of the nutrients contained in the obtained digestate. The wastes used were poultry litters after six, seven and eight production lots, as well as the sifted wastewater from one Piglets Producer Unit (PPU). Higher biogas production (p
