Feasibility of biogas and energy generation from poultry manure in Brazil.

The aim of the present study is to experimentally measure the volume and composition of biogas produced from the anaerobic biodigestion of laying-hen manure from poultry farms in Itanhandu-MG, Brazil, so that the biogas can be used to generate energy. Two experiments (E1 and E2) were used to characterise the biogas quantities and compositions at room temperature and at a controlled temperature of 36 °C, respectively. The biogas production and calculated net power from the exploitation of biogas energy were compared with the results obtained from methods proposed by the Environmental Company of the State of São Paulo (CETESB, an acronym in Portuguese) using the 'Biogas: Generation and energy use - effluent and rural waste' software 1.
