Abstract

The objective of this research is to evaluate the energy potential of cow dung and corn cob inputs, with a view to their valorization. The research made it possible to determine the characteristics of the physicochemical parameters of cow dung and corn cob. The results obtained in terms of cow dung are: Humidity (79.17%), Dry Matter (20.83%), Organic Matter (OM) 57%, density (208.33 kg/m3), Carbon rate 32.53%, Nitrogen rate (1.82%) and the C/N ratio (21.30) and those of the corn cob, Humidity (38%), Dry Matter (62%), Organic Matter ( 67%), Density (250 kg/m3), Carbon rate (39.7%), Nitrogen rate (2.55%) and C/N ratio (15.23). These results compared to those in the literature revealed a very good coincidence. Two experiments on the methanization of these inputs were carried out, the anaerobic digestion lasted 27 days, in a temperature range of 27°C to 31°C (mesophilic range). It was obtained for: corn cob 28.4 liters, cow dung 22.6 liters and for co-digestion 38.7 liters. In perspective, we recommend the continuation of these studies.
