Abstract
Due to rapid growth of population and industrial globalization day to day energy demand increases and has an adverse effect on the fossil fuel depletion. This is the major problem accounted for the present and future economy. So in order to reduce our energy demands, there should be a need of distinguishing new concepts on renewable energy source because they are ecofriendly in nature. In the present paper, kinetics study on the effect of water hyacinths in food waste biogas production was carried out. The experiments consists of bio digester setup of 75litres capacity with 10% solid concentration at mesophilic temperature range of 35˚C and 20days retention times and by using modified Gompertz equation kinetics were determined for each bio digester. The kinetic parameters are Biogas yield potential (P), Maximum biogas production rate (Rm) and the Duration of lag phase (λ) were estimated for each bio digester. In the experiments cow manure is used as the inoculums and food waste is added daily .The results show that the mixture of water hyacinths and food waste will enhancing the biogas productions of about 1.2% when compared with food waste substrate alone.
