Experimental Production and Comparison of Biogas Using Co- Digestion of Organic Waste

Abstract

Environmental pollution is one of the major problems plaguing the modern world today. The environment and the various elements in the environment need energy to meet their need. So, there is a need to produce energy from different sources. Solid Waste is one such material that can be used as a source for deriving energy. The studies on conversion of solid waste to energy have resulted several alternatives including the biogas generation from biodegradable organic waste. There are several alternatives in the estimation of biogas yield from the bio-degradable fraction of solid waste. The different types of biodegradable organicwaste may comprises of cow dung, pig waste, poultry manure, food waste, vegetable waste, kitchen waste etc. The present study focuses on production of biogas using cow dung with vegetable waste and poultry manure. In this study, by doing experimentation it is observed that the production of biogas from co-digestion of different organic wastes is more than individual waste. The highest yield of biogas is obtained from co-digestion of cow dung with poultry manure, than co-digestion of cow dung with the vegetable waste. Waste obtained after the production of biogas is used as a natural fertilizer for the growth of crops and fields and it gives good yield. By doing experimentations like energy recovery from solid waste, the conservation of non-renewable energy resources may be possible and it also helps to protect our environment.
