In India, primarily cattle dung is being used as an organic substrate for the production of biogas, however, majority of biogas digesters are underfed. Thus making it essential to evaluate other available organic sources for biomethanation. Various other animal wastes like poultry droppings, sheep droppings, rabbit droppings etc have been evaluated for biomethanation. Beside this, plant and crop residues have also been subjected to the process of anaerobic digestion under different conditions.
