A dairy farm waste which include milk waste; unconverted feed and bedding; cow manure and cow slurry water have been applied as raw materials to produce renewable energy using a continuous flow membrane-less microbial fuel cell (MFC). The COD content decreased with 98% from 33;600 J/L to 558 J/L within 6 days by turning the organic content into electricity and hydrogen. The voltage generated reached a peak of 1.6136mV; which indicating that dairy farm waste can be an appropriate resource for MFC. The total energy of hydrogen gas was 38;338J/L on the sixth day; which suggesting that about 80% of the energy stored in the COD was transferred into hydrogen gas. The nitrogen content of the farm waste slurry also decreased 20% during the first 24 hours indicating that MFC can be used for nitrogen harvesting.
