CARACTERISATIONS ENERGETIQUE ET ENVIRONNEMENTALE DE LA BIOMETHANISATION PILOTE APPLIQUEE AUX DEJECTIONS ANIMALES

Abstract

This study interested in monitoring energy (quantitative and qualitative) and environmental performances at various pilot digesters of animal biomass.Main results are:The combined effect of the diet and the substrate on quantitative experimental productivity of gas is in favor of poultry digesters continuously fed. The biogas produced has better potential especially in industry. The environmental evaluation virtually shows a certain interest on the depollution for industrial digester.
