title: Potential of anaerobic digestion for material recovery and energy production in waste biomass from a poultry slaughterhouse.
abstract: This study was carried out to assess the material and energy recovery by organic solid wastes generated from a poultry slaughterhouse. In a poultry slaughterhouse involving the slaughtering of 100,000 heads per day, poultry manure & feather from the mooring stage, blood from the bleeding stage, intestine residue from the evisceration stage, and sludge cake from the wastewater treatment plant were discharged at a unit of 0.24, 4.6, 22.8, and 2.2 Mg day(-1), consecutively. The amount of nitrogen obtained from the poultry slaughterhouse was 22.36 kg 1000 head(-1), phosphate and potash were 0.194 kg 1000 head(-1) and 0.459 kg 1000 head(-1), respectively. As regards nitrogen recovery, the bleeding and evisceration stages accounted for 28.0% and 65.8% of the total amount of recovered nitrogen. Energy recovered from the poultry slaughterhouse was 35.4 Nm(3) 1000 head(-1) as CH4. Moreover, evisceration and wastewater treatment stage occupied 88.1% and 7.2% of the total recovered CH4 amount, respectively.
