Kitchen Waste Utilization Using Biogas Plant—Need of the Hour

Kitchen waste is a preferable source for biogas production at community level owing to its high biodegradability, calorific values and high organic content. Kitchen waste is generated in bulk in community places due to improper waste management. Biogas is one of the sources of renewable and eco-friendly energy which is produced by decomposing organic waste by the anaerobic digestion process. It has high methane content up to (55–60% by volume) so is the most favoured source of bioenergy. In the present paper, the analysis of the biogas plant based on kitchen waste from the restaurants is presented. An analytical calculation of biogas output and the payback period of the biogas plant for a different quantity of the input kitchen waste is revealed. Comparative study between biogas and LPG gas is analysed on the main parameters of calorific value and cost of fuel per kg. After the comparative study, the cost of LPG saved per day is calculated and collated with the installation price of a biogas plant which gives payback period. This paper guides on food waste management and the utilization of renewable energy resources as alternatives to LPG gas.
