The Production of Biogas from Agricultural and Animal Wastes and Its Utilization in the Integrated Energy System (Biogas)*

T he tasks of this research; review of biogas and energy production technologies, system simulations and decision support system insert ignore into journalissuearticles values(DSS); modeling, design and development of two lab-scale insert ignore into journalissuearticles values(one for animal waste and one for agricultural waste); and one pilot scale insert ignore into journalissuearticles values(250 kWe capacity); integrated biogas plant, integration of the pilot plant with energy conversion systems, experimental studies, techno-economical analysis of the biogas production, and life- cycle analysis were determined. The pilot biogas plant consist 2 reactors that have 2089 m3 net volume each and they are connected to each other. The volume of the final manure storage is 1000m3. The retention time at the plant is 47 days; ratio of organic dry matter is 9 % and the fermentation temperature is 35-40 o C under mesophilic conditions.
