Abstract

This present work concerns the trial to evaluate the energy potential of pig dung by the production of biogas in the urban municipality of N’Zérékoré. In order to achieve the expected results, we carried out: a census of the pig herd, an evaluation of the average daily production of dung, a physicochemical characterization of the samples and an evaluation of the energy potential of the pig dung of the locality. The main results obtained are: the pig herd in the city (4845), the average daily production of dung per animal (2.30 kg/d), the total daily quantity of dung (11143.5 kg/d), the parameters physicochemicals of pig slurry, humidity (53.83%); dry matter (44.26%); organic matter per dry matter (81.39%); density (650.36 kg/m3); Carbon (47.20%); Nitrogen (1.8%) and Carbon per Nitrogen ratios (26.22); daily biogas production (3375.982 m3/d) and energy potential (15461.996 kWh/d).
