In this study kitchen waste and sewage sludge were co-digested anaerobically to produce biogas with the aid of engineering granules to enhance biogas production. Co-digestion was conducted for mesophilic and thermophilic conditions in a 20L bio digester for a period of 30 days. Hycura was inoculated to enhance biogas production. The co-digestion resulted in significant degrease of the total volatile solids and chemical oxygen demand of the bio-waste by >75%. Mesophilic conditions favored high quality biogas production with methane content as high as 74%. Inoculation with Hycura hindered H2S production which enhanced the quality of the biogas and makes it easier for upgrading
