Abstract

Renewable energy sources are now essential in our lives. Conventional fuels need to be replaced, for the most part, if not entirely, by renewable energy sources as the need to reduce environmental pollution is now imperative. Exploiting renewable energy sources such as solar and wind offers many benefits both environmentally and economically. This dissertation evaluates, economically and technically, an investment in a 499 kW biogas plant. The aim of this investment is the production and sale of electricity from the combustion of biogas which will be produced through the process of anaerobic digestion (A.D.) and using as raw material agricultural waste. First, an introduction is made around renewable energy sources and their importance, as well as their levels of use at various intervals. In addition, the process of anaerobic digestion, biogas production, the term biomass and the facilities of which a biogas plant is composed are described. The following is a feasibility analysis with a mixture of raw materials to be disposed of from agricultural waste. The investment was evaluated using the following indicators: Net Present Value (NPV), Internal Rate of Return (IRR), repayment period of the initial capital and the return on sales and return on equity indicators. The investment project under consideration is attractive and profitable.
