Windpower Nepal carries out the feasibility study of waste-to-energy Plant (Biogas plant) for effective management of wastes. WPN has conducted feasibility studies of a proposed biogas plant in Damak Municipality, Birtamod municipality, Bhadrapur Municipality and Hetauda Sub-Metropolitan City. A number of variables, for example, type and quantity of feedstock, geographical location, operator, digester design, mixing, heating, temperature, etc. affects the optimum biogas yield. Any single factor among this could decide the ultimate feasibility of the project.
