Anaerobic Co-Digestion of Agricultural Waste with Cow Dung for Biogas Production

The aim of this study is investigating the methane production through anaerobic co-digestion of rice straw (RS) as one of the famous agricultural residues and cow dung with different total solids. This study is carried out in lab-scale by using batch operation. To evaluate the performance of anaerobic co-digestion process of agricultural residue with cow dung, the experiments of the study were conducted in duplicate or triplicate. The anaerobic co-digestion process was operated in 500 mL batch reactors maintained under Mesophilic conditions (35oC). Rice Straw (RS) produced the maximum value of methane production; methane yield; chemical oxygen demand (COD) removal and VS reduction at 4% total solids (TS).
