Microbial Fuel Cells (MFCs) are bio-electrochemical devices that use the power of respiring microbes to convert organic matter into electrical energy. Thus, they can help treat wastewater and also generate electricity. Realising the vast potential these cells have, scientists are finding ways to improve their performance and efficiency.

While the country struggles with various problems related to waste management, scientists from the Indian Institute of Technology, Bombay, have come up with a novel solution to turn waste to wealth. The researchers develop a method to generate energy from landfill leachate and microbial fuel cells.
