The need for renewable energy is increasing in the society. Many forms of renewable energy is available at present. Microbial fuel cell (MFC) represents a new form of renewable energy, where electricity can be generated from wastewater with the use of microorganisms as biocatalyst. This technology uses the bacteria present in the wastewater to degrade the organic matter and simultaneously produce electricity. Both electricity production and wastewater treatment would reduce the cost of treating primary effluent wastewater. Microbial fuel cell (MFC) was made employing low-cost materials. Experimental data showed the feasibility of power generation from wastewater treatment. The study documented the advantage of both wastewater treatment and electricity production in a single system.
