In this research, a single stage fed-batch anaerobic digester with total volume of 200 liters was used. It
was operated at ambient temperature in the emsophilic range (27-31°C), yet the temperature and moisture
were monitored daily using thermo-hygrometer. A gas collector was provided for collection and
determination of the amount of biogas. The content of methane concentration produced in the reactor was
monitored weekly.
