Algae-assisted Microbial Fuel Cell for Electrical Energy Generation and Wastewater Treatment

This research investigates the potential of microalgae as a sustainable resource for bioenergy production using a microbial fuel cell (MFC)[1] technology. It explores the general taxonomy and characteristics of algae, outlines the different generations of biofuels, and highlights the benefits and limitations of algae-derived biofuels. Particular emphasis is placed on integrating bio-electrochemical systems that simultaneously treat wastewater and generate electricity. The study demonstrates that utilizing algae in MFCs not only supports organic biomass production but also enhances nitrogen recovery and energy efficiency. Through experimental trials with various electrode modifications, the research confirms that algal biomass can effectively function as both a biofuel substrate and a sustainable energy solution. These findings propose a closed-loop, self-sufficient energy system with minimal environmental impact, offering a viable alternative to fossil fuels.
