The efficacy of an anaerobic digester-based power production from various feedstocks

ABSTRACT

Biogas is one of the most promising renewable energy fuel sources obtained from various organic matters and used for energy requirements. This work is focused on the usage of biogas in power production. The main aim of this study was to evaluate the different factors that affect the power production during anaerobic digestion. This study examines the usage of Organic Fraction Municipal Solid Waste (OF-MSW), wastewater sludge, and co-digestion of both OF-MSW and wastewater sludge for power production. The digestions are performed under mesophilic conditions at an optimum temperature of 36°C. The maximum power produced is 128 kW when using OF-MSW alone and 48.9 kW for co-digestion (50% OF-MSW + 50% wastewater sludge) and 35.5 kW for wastewater sludge. The paper also focuses on various factors such as pH, temperature, and nitrogen concentration and its influence on power production.
