Review on Biogas Production from Co- Digestion of Cow Dung and Foodwaste with Water Hyacinth

With Increasing Energy Demand in the World and to keep Environment Friendly, biogas technology has attained a notable position for the future scope. This paper tells about a comprehension review on anaerobic digestion of cow dung and food waste with Water hyacinths to enhance biogas productions. Water hyacinths are treated as waste in rivers, ponds, but they have high potential in biogas production. Food wastes are having rich organic nutritive value and high calorific value. By anaerobic digestion water hyacinths are mixed with cow dung which acts as the inoculums for the digester. Kitchen waste is added as the daily feed substrate to the digester. The digested slurry from the digester is rich in nitrogen, phosphorus, and potassium content, so they can be used as fertilizers and the biogas obtained is used for alternate for LPG.
