Bioconversion of Food Waste with Cosubstrate to Electricity using Microbial Fuel Cell

Abstract

Bioelectricity generation from canteen based food waste in microbial fuel cell (MFC) is an interesting alternative energy producing technology. In this research work, an equal proportion of confectionery wastewater and hostel food waste was homogenised and used as substrate. Agar salt bridge was used as proton exchange membrane (PEM). At the end of 212th h of the experiment, the COD concentration decreased to 2800 mg COD/L with the COD removal efficiency of 85.86 %. A maximum potential of 2250 mV and current of 22.50 mA with external resistance of 100Ω at the end of 65th hour was generated.
