Production of purified methane and bio-fertilizers by anaerobic digestion of food waste

Abstract

Anaerobic digestion is a biochemical process in which the organic substances are digested by microorganisms to methane (biogas) and carbon dioxide in the absence of oxygen. This process is spontaneous but the control on large scale requires good knowledge. The search for appropriate models of this entire system of bio gas production with filtration process by benefitting the society, improving world’s economy, and protecting the environment at the same time making biogas as a sustainable energy resource is covered. The aim of this paper is filtration of raw bio gas and methane production in all economic aspects. For this, a low costbio gas system by separating the other gases from methane, called chemical scrubbing was developed. Purified methane obtained can be used in various fields as domestic and industrial (cooking, electricity, transport and other power application).
