Efficiency of food waste as fuel source in Microbial Fuel Cell: A review

Abstract

This review article discussed about the food waste as a source of bioelectrical energy. Every year the global energy demand increases. While petroleum products currently supply much of this demand, the increasing difficulty of sustained supply and the associated problems of pollution and global warming creates unbalanced energy management and require power sources that are able to sustain for longer periods. Renewable energy generation and waste disposal are two key challenges for the sustainability of future societies. Microbial fuel cells (MFCs) as an alternative renewable technology can run in solid phase and capture bioelectricity from food waste. Food waste being readily available is found to be the potential source for bioelectricity production by optimizing several important factors are optimized, such as the type, number and quality of electrodes, type and amount of substrate, microorganism community, system configuration, and different parameters which increases the amount of electricity generated. Solid microbial fuel cells (SMFCs) were reported to produce relatively small amounts of energy compared with other substrates, but SMFCs are still promising to achieve energy requirement of the future. So this review demonstrates the works of different scientist who potentially produced bioelectricity and looking further for improvements.
