Economic feasibility of producing energy from livestock waste by DRANCO anaerobic digestion process

In recent years the growing trend of energy consumption has created energy crisis in the world. In our country the use of renewable energy can have a special place due to the growing need for energy and diminishing fossil fuel resources, protect the environment, reduce air pollution, restrictions on electricity and the fuel supply for remote villages. Due to the significant amount of the annual production of biomass sources in Iran the importance of using these resources for biogas production is more specific. The production of biogas using anaerobic digestion technology and its application in CHP plants in Iran can supply part of the required energy and achieve sustainable development. In this study has been done economic calculations for biogas plant as a case study for combined heat and power production. The results show that during the project life (20 years),the Internal Rate of Return (IRR) is 19%, the net present value (NPV) is equal to 180,587,908 and the ratio of benefits to costs is equal to 1/032. Financial evaluation of energy production in this system shows it is economical to run.
