Abstract

The management of organic waste using an anaerobic reactor offers the potential for renewable energy production and nutrient recovery. This study evaluates the performance of a 3,000 L fiberglass anaerobic reactor designed to treat a mixture of kitchen waste, cow manure, and water in a 1:1:1 ratio. The process was conducted under mesophilic conditions (30–38 °C) over a 40-day batch cycle. The reactor produced a total of 63.75 m³ of biogas with an average methane content of 59.3%, equivalent to 0.193 m³ CH₄/kg VS. Additionally, the system produces approximately 2,700 kg/month of liquid effluent and 900 kg/month of stabilized solids. These results demonstrate the efficiency of substrate bioconversion and the potential for utilizing residues as organic fertilizer. This study emphasizes the technical feasibility of using a community-scale fiberglass reactor for organic waste treatment with measurable performance parameters.
