Abstract

The objective of this study was to produce biogas from food waste added with crude glycerin produced from biodiesel processes by using 200 L of a semi-batch anaerobic reactor. In start-up state, food waste was fed to the reactor at the range of average organic loading rate of 0.306-1.245 g/Lreactor-day (56.6-230.2 g/day) giving the average methane yield at room temperature of 0.465 m3CH4/kgCOD and average biogas yield of 0.789 m3biogas/kgCOD. In addition of crude glycerin at food waste loading of 1.245 g/Lreactor-day, average biogas volumes was increased from 36.8 L/day to 72.2 L/day and 90.4 L/day after adding with 30.8 mL/day and 46.3 mL/day of glycerin, respectively.:
