GUWAHATI: The Indian Institute of Technology Guwahati (IIT-G) has invented the Microbial Fuel Cell (MFC), a bio-electrochemical device that can generate green energy by treating wastewater. According to IIT-G sources, the use of organic materials such as wastewater in MFC makes it an environmentally benign technology that generates bioelectricity while also managing waste.

Prof. Mihir Kumar Purkait and his PhD student Mukesh Sharma of the Department of Chemical Engineering led the research, which was funded by the Central government's Department of Science and Technology (DST). 

According to the institute's announcement, the bio-electrochemical device converts chemical energy inherent in organic substrates into electrical energy via bacteria.  The research shows that the created CEMs are less expensive and work better than other membranes, assisting in charge separation and potential development.

Rapid population growth has resulted in increased energy demands and environmental concerns, prompting the development of renewable and sustainable energy technologies.

According to the statement, in addition to many renewable energy sources (solar, wind, tidal, and geothermal energy, among others), the sustainable energy sources also include 'Blue Energy' energy harvesting sources, which have no negative environmental impact.
