| dc.description.abstract | Disposal of untreated tannery wastes into land and water bodies results in water pollution and air pollution which in turn leads to greenhouse gases. With increased emphasis on climate change mitigation, waste management and, re-use of waste as a resource new environment friendly technological approach such as anaerobic digestion has received increased attention. This research presents the experimental results of anaerobic digestion of tannery solid waste and water hyacinth in different proportions. Four bench scale anaerobic digesters with different feedstock composition of 100%, 75gram:25gram, 50gram:50gram, and 25gram:75gram (Tannery solid waste to Water hyacinth) have been used in the experiment. The retention time of the experiment ranged 82 days for the digester containing 75gram Tannery solid waste and 25gram Water Hyacinth at ambient temperature of 37 o C and pH of 7. Estimation of biogas produced and its quality was determined by the water displacement method using the biogas analyzer for each digester. It was found that, the highest volume of biogas was 6540Lit and with a methane content of 72.05% this produce produced by the digester containing 75% Water Hyacinth waste and 25% tannery solid waste. The lowest biogas concentration (2540Lit) of methane concentration 68.06% was produced by digester containing tannery solid waste alone. | en_US |
