Abstract

Biogas is a non-exhaustible of energy which can be formed from anaerobic fermentation of different types of biodegradable waste such as food waste, plant waste, animal waste sewage and other organic waste. The typical composition of Biogas includes CH4 (50–70%) which is responsible for maximum energy content along with CO2 (25–50%) that can be collected, stored and supplied. Biogas acts as a multipurpose and an eco- friendly sustainable resource of energy which can be utilized for cooking, electricity generation, lightning, heating etc. Biodegradable waste specifically produced in large amounts as a kitchen waste. In modern society, the solid waste per capita has been consistently increasing as of increase in population and change in socio-economic-cultural habits. The biogas production through the kitchen waste thereof provides a solution of disposal of solid waste. The bio gas production through anaerobic degradation pathways can be controlled and enhanced with the help of certain microorganisms and advancements of new technologies. In this research work, an attempt is being made to produce the biogas from kitchen and food waste collected from hostel mess of Chitkara University, Punjab and a novel method of production of microorganism has been also proposed for fast degradation of waste. Under this project, a survey for the estimation of daily production of organic waste from hostel mess has also been done for fifteen day.

Highlights

Around the globe, Wealth from Waste technologies get recognized and adopted at a very fast pace to handle challenges such as increasing energy supply and waste management (Mutz et al, 2017)
Biogas is created by anaerobic assimilation with anaerobic microbes or methanogens, which digest all biodegradable material inside a closed framework
In the present research work, the microbial slurry has been prepared from the cow dung, jaggery and water mixed in varying ratios of 2:1:1, 3:2:1, 4:2:1, 4:3:1 ratio in different containers

Summary

Introduction

Wealth from Waste technologies get recognized and adopted at a very fast pace to handle challenges such as increasing energy supply and waste management (Mutz et al, 2017). Biogas production from waste is such a sustainable power technology proven as a great success in access to clean, affordable and renewable energy. Biogas is a natural production of energy gas which is mingling of different gases formed during the fermentation of biodegradable organic material in the absence of oxygen gas. Biogas is created by anaerobic assimilation with anaerobic microbes or methanogens, which digest all biodegradable material inside a closed framework. This closed framework or system is called an anaerobic digester, bio-fermentation tank, or a bioreactor (Yasar et al, 2017)
