Bio-Electricity Generation by Using Organic Waste in Bangladesh

Resource recovery and recycle of organic waste is a major concern now-a-days all over the world. This present study deals with the Microbial Fuel Cells (MFC) using kitchen garbage to produce electricity as well as recycle of organic waste and its potential use in Bangladesh. A rectangular acrylic container (10 x 10 cm) was used as the cell. The container was filled with well mixed kitchen garbage (120 g), leaf mold (120 g), effective micro-organisms (15g) and distilled water (80 g). The data logger stored the data of voltage in every 20 minutes in the constant room temperature at 25C for 45 days. It was observed that voltage increased rapidly during initial time (first 2 days), then gradually increased and reached to peak after 2 weeks and after reaching the peak gradually decreased. The maximum power was 682 mW/m during the laboratory test of the MFC by using the kitchen garbage.
