Enhancement of Methane Production from Tea Waste and Pumpkin Waste using Human Urine

Biogas is an alternate source of energy in rural areas and this biogas can be produced from food or agricultural wastes. Huge amount of tea waste is wasting from tea shop and pumpkins from the market. Human urine is unhygienic to the open environment, whereas it can be utilized as a biocatalyst for the enhancement of production of biogas from these wastes. In this study predigested tea and pumpkin wastes were treated with human urine to enhance the biogas production by improving the C:N ratio. Maximum amount of methane was obtained from pumpkin than tea waste due to higher percentage of carbon. Maximum CH4 yield (263 ml) was observed in case of pumpkin waste (100 g) by adding 150 ml of urine.
