Microbial Fuel Cells (MFCs) is a technology that can produce electricity whilst at the same time treat wastewater. MFCs convert the chemical energy of organic substrates into electricity through catalyzing the anaerobic oxidation process in the anodic compartment by bacteria as a catalyst. This study investigated the generated electricity using peel papaya (Carica papaya) waste. https://www.alarecre.com/NFL-Atlanta-Falcons-Double-Vision-iPhone-13-Pro-MagSafe-Case-p92343/
