Abstract—Ranges of environmental problem from human activities have become a global problem. Therefore, reducing volume of waste such as a nigh soil and food wastes to use as resource materials were considered. The anaerobic batch reactor experiments were conducted to investigate the COD removal and biogas production from night soil and night soil with additional 10% food waste. The 4 batch reactors experiment were conducted, night soil were contained as a fermentation materials for reactor 1-3 and for reactor 4 the night soil with additional 10% food waste were investigated to compare. The experiments were operated at room temperature varies from 25-37
oC within 3 months experiment. The results show 90% COD removal and about 50% methane production occurred in this experiment. sTKN and sTP have also investigated in this experiment. sTKN concentration remain constant during experiment period and slightly increase of sTP concentration were appeared.
