Potential Energy Production from Biogas Economically and Environmental Profitable. Case Study: Establishing a Batch Digester in “Fogi” Farm

Abstract

Recently the use of biomass for biogas production is very limited in Albania. According to data acquistion from the study, the highest share in the entire structure of urban solid waste is that of organic waste 41-61.2%. A large part of these waste are bio digestible and can used for production or utilized as potential substrate in anaerobic digestion to produce biogas, a renewable source of energy and environment friendly too. Live stocks waste and especially cow manure farms are concerned in this study because there are a high number 11813 of them are spread all over Albania. In addition, the amount of cow manure exceeds 37,693.92 ton/year. In this case study is presented a cow farm located near Tirana, capital city of Albania with 200 cow heads which in the future will become 700 cow heads. The total amount of cow manure produced in this farm is 1825 ton/year, a considerable quantity of manure available for biogas production. This paper presents the type of digester, calculation of the biogas production yield, the optained energy, the pay back period of the initial investment and the net present value of this farm batcher digestor.
