The objective of this research was to compare biogas production and COD removal between rice straw pretreated with 6%NaOH and rice straw with non-pretreatment during thermophilic anaerobic fermentation. Result showed that the max daily gas production, total gas production and COD removal of pretreated rice straw were 61.34%, 55.23% and 48.72% higher than the unpretreated. Therefore, 6%NaOH pretreatment contributed to anaerobic digestion efficiency and biogas production.
