Abstract:
Biogas is produced by the biological processes of anaerobic methane fermentation. It is a mixture of methane, carbon dioxide and trace amounts of other gases. By-products of the sugar industry are an efficient source of agricultural biogas. Sugar beet pulp and waste mass plant is characterized by a high content of dry matter and organic dry. The purpose of this article was to develop the economic analysis for biogas plant working at sugar factory and to show the energy balances and material and then calculated the main economic indicators such as Cash Flow (CF), Net Present Value (NPV), Internal Rate of Return (IRR) and Discounted Payback Period (DPP). It was found that the biogas plant operating at a sugar factory can be a profitable investment and DPP amounted to 8 years. However, these results are estimates and in reality they may changed.
