This study investigated the co-anaerobic digestion of cow dung and sawdust with thermochemical pretreatment to enhance biogas yield and energy recovery. Sawdust was pretreated with sodium hydroxide and thermally conditioned before co-digestion with cow dung at 50:50 and 75:25 ratios. Results showed that pretreatment...
