In this work, the biodiesel was produced from municipal sewage sludge contains high free fatty acids (FFA) act as a feedstock. The main sources are primary sludge (P.S) and secondary sludge (S.S) was used as lipid source to compare high yield percentage for the transesterification reaction. Through the base transesterification process, the yield percentage of biodiesel 90.3% was obtained at the optimum conditions of 2% NaOH, chloroform–ethanol (2:1) ratio, 600 rpm and 60 °C temperature for 90 min. The produced biodiesel was analyzed and confirmed by GC-MS. The properties of biodiesel were analyzed and it was found on the inside of ASTM standard limits. Hence, municipal sewage sludge serves as a valuable renewable raw material for biodiesel production.
