Electricity generation from food wastes and spent animal beddings with nutrients recirculation in catalytic fuel cell

Abstract A biochemical system was used for electricity generation from food waste (FW) and spent animal beddings (SAB). The wastes were blended and fermented anaerobically to produce fermentation liquids used as fuels for running a catalytic fuel cell. The fermentation liquids were analyzed for thei...
