This work consists in studying various possible valorizations of the rural biomethanisation applied to the bovine dejections. The follow-up of the adopted digester related to: the estimate of the qualitative productivity (% CH4, % CO2, % H2S and % H2; LCV and HCV) before and after conditioning. For the analysis of the gas composition and the estimation of the calorific values, we had recourse to the technique of chromatography in gaseous phase (CGP); analysis of certain environmental parameters (SM and BDO5), in order to establish the corresponding assessments of depollution; possibilities of agronomic valorization except ground of the residues of the biom
