ABSTRACT: Electric current from organic waste of poultry droppings were generated with A Microbial Fuel Cell (MFC) technology to evaluate affects of temperature (30 to 50oC), 100g/l, 300g/l and 500g/l slurry concentrations prepared with the distilled water and inoculated when introduced into the anodic chamber. A constant concentration of 50g/l of the oxidizing agent (Potassium ferricyanide) at the cathode chamber was prepared to evaluate the voltage and current generated by the set up for 7 days in each case. Higher slurry concentrations were observed to generate higher initial current and voltage than in lower concentrations. Higher slurry concentrations also demonstrated sustained power generation up to the day 6 before decline. A maximum current of 1.1V and 0.15 mA was achieved while the temperature variation was observed to have minimal effect within the range considered at low concentration. A (MFC) is a biochemical-catalyzed system, capable of generating electricity as a by-product, also providing an alternative method of waste treatment. Application: Alternative power source and waste treatment.
