Quali-Quantitative study of biogas production from bio-digestion of cutting poultry

The purpose of this study was to evaluate the biogas production and the potential production obtained with the anaerobic digestion of cutting poultry carcasses. The carcasses were used to supply batch digesters with 8 liters of capacity of fermentation material. To perform this process, analysis content of total solids (TS) and volatile solids (VS) were performed. We used a system of three treatments, TRA (Treatment A) 8% of ground chicken and 92% of water; TRB (Treatment B) 8% of ground chicken, 20% of swine inoculum and 72% of water; TRC (Treatment C) 13% of ground chicken, 20% of swine inoculum and 67% of water. The results were evaluated statistically showing that TRB treatment has shown better performance compared to the other two treatments, resulting in obtaining biogas at 0,3854 m3/kg TS and 0,4158 m3/kg VS, with an average production of methane (CH4) of 75.63%, thereby producing 0,2748 m3 of methane per kg of TS added and 0.2964 m3 of methan/kg VS -1 (???), with a hydraulic retention time (HRT) of 31 days.
