The present study examined the possibility of using rice husk (RH) inoculated with ostrich dung (OD) in the anaerobic co-digestion to produce biogas. Four digesters were conducted to observe the performance of the co-digestion process in batch scale for 25 days. Grounded RH were pretreated with five pretreatments, which were ultrasound, hydrothermal, combined hydrothermal-ultrasonic, NaOH (3% w/v) and combined 3% NaOH-ultrasound pretreatment, and these pretreatments caused an increase in biogas production by 50.72%, 34.72%, 57.9%, 60.85%, and 78.65%, respectively, compared to control. On the other hand, the same arrangement of above pretreatments led to improve the cumulative productions of methane by, 66.11%, 44.76%, 74.27%, 77.89%, 101.62%, respectively, as compared to un treated RH. Thus, combined pretreatments including 3% NaOH-ultrasound and hydrothermal-ultrasonic pretreatment is make to enhance production more of biogas and methane yields than sole pretreatments. It was stated there was well compatibility between estimated and predicted values for methane (> 0.95).
