This study investigated the effectiveness of cow
dung for biogas production and presented the performance characteristics of the anaerobic digestion in batch and semi-continuous operations. Under these conditions, the cow dung digestion reaches 47% VS reduction and approximately 48.5% COD reduction with biogas yield of 0.15 L biogas/kg VSadded. Despite large variations in pollutants concentrations, an improved performance of anaerobic digestion of the biodegradable fraction of cow dung was achieved. The results showed that cow dungmight be one of feedstock for efficient biogas productionand waste treatment.
