Bio hydrogen generation from kitchen waste in an inclined plug flow reactor

Abstract The performance of inclined plug-flow reactor of 0.15 m 3 for hydrogen generation from kitchen waste using 100 °C heat treated biogas plant slurry as inoculum under solid phase anaerobic digestion was studied. The reactor pH stabilized at 5.6 after 21 days of its operation. 40% VS degradation was obtained and it generated 72 mL H 2 /gVS added. The soluble metabolites in the reactor were predominantly butyric acid (45–50%), acetic acid (20–30%) and propionic acid (10–20%).
