The rational management of waste, as well as the penetration of renewable energy sources (RES) in the energy mix are the basic parameters of the European and Greek energy and environmental policy. The utilization of high organic load residues for the production of electric and thermal energy through biogas plants is the most modern technological application that combines the rational management of waste with the production of clean energy.

In this study, after clarifying the concepts of biomass and RES, a brief description of the biogas units and the resulting benefits from their operation is carried out. Then, the theoretical and available biomass potential of the Municipality of Pogoni and the quanitities of biogas, which can be produced, are calculated. The construction of a biogas unit for electricity and heat production and its feasibility has been also examined. It appears that this unit is not just the best available technique for livestock and agricultural wastes management and utilization, but also a particularly attractive investment.
