A simplistic theoretical study of anaerobic digestion in order to predict the biogas amount of agricultural waste is proposed. A wide variety of models exist, but most of them rely on algebraic equations instead of biochemical equations and require many input parameters as well as computation time. This work provides a simplified model that predicts the biogas amount produced and could be applied for agricultural energy feasibility studies for instance dimensioning bioreactors digesting animal waste slurries. The method can be used for other feedstock materials and repeated for other similar applications, in an effort to expand anaerobic digestion systems as a clean energy source.
