Abstract

Wastewater contains a large dose of complex biological and chemical materials that can cause serious health, hygiene, and environmental problems. Microbial fuel cells (MFCs) are bioelectrochemical systems that directly convert the chemical energy of wastewaters into electrical energy directly by utilizing the metabolic (catalytic) activity of microorganisms. MFC technology has emerged as a competent technology for simultaneous wastewater treatment and electricity generation. Food processing and beverages are known to generate ample amount of the waste. These wastes contain rich organics fraction and high moisture that makes those a good candidate as anolyte in MFCs. MFCs hold promise toward sustainable power generation and food-based wastewater treatment. This chapter discusses the treatment of food processing and beverage industry wastewaters by MFC technology.
