Biomethanation of Agro-Waste in Combination with Cattle Dung

Abstract

The potential of different agro-wastes like green grass (Cynodon dactylon (L.», bagasse, algae (Enteromorpha spp.), banana stem and water hyacinth (Eichhomia crassipes) in combination with cattle dung for methane production by anaerobic digestion have been evaluated. The results indicate that these wastes can be exploited for methane generation in combination with cattle dung. Best results were obtained with green grass when it was combined with cattle dung in the ratio of 1:4.
