Production logistics and participation of biogas in obtaining primary energy in Poland

Abstract

One of the primary wastes generated in wastewater treatment process is the sewage sludge. Sewage sludges are a substrate of methane fermentation process, from which biogas is obtained. Biogas is a renewable energy source obtained by processing the biomass. In accordance with European Union directives, we should strive to increase biogas production and its share in primary energy acquisition. In this article, the characteristics of biogas from sewage sludges, in terms of the chemical composition of the gas mixture, were noted and its participation in obtaining energy from renewable sources and in total primary energy in the case of Poland was analyzed. Moreover, logistics biogas from sewage sludges production issues, which relate to, among others, location production plants, sourcing activities, as well as feedstock management and digestate waste management were discussed.
