Abstract

Water hyacinth and cow dung are the two waste which can be used to generate energy through biogas which is an alternate fuel save on the fossil fuels conventionally. In this study, the possibility was explored to determine the efficiency of lignocellosic waste from water hyacinth blended with cow dung for a biogas yield at a laboratory scale. A different combination of cow dung and water hyacinth were done. The digestion of residues was undertaken by batch-type anaerobic process, it was operated at a temperature 35°C for a period of 30 days. Gas chromatography was used to quantify the different component of biogas produced by the substrate. The results indicated that lignocellosic waste blended with Water hyacinth (WH) yield a methane of 24% in the combination of (50%)WH + (50%) CD. The lignocellosic waste was analysed for total solids, volatile solids, total dissolved solids, moisture and pH content before and after the treatment for methane production in anaerobic digestion. This study thus forms an attempt in a lab scale level to use the unwanted weeds as substrates for methane production
