BIOGAS PRODUCTION FROM ANAEROBIC DIGESTION-A SYSTEMATIC REVIEW.

Abstract

……………………………………………………………… Biogas, a renewable source of energy has been the focus of research for the past decades. It is simple to produce and environmentally friendly. Due to the current increase in population, emission of greenhouse gases and the UN concern to achieve 100% renewable energy globally by 2050, the use of biogas for electricity and for combined heat and power is the surest way forward. Anaerobic digestion thus far has been the surest way to achieve in the production of this renewable energy. The process, however, involves the consortium of microorganisms to breakdown feedstocks such as food waste and agricultural biomass through a complex pathway to generate mainly the methane and carbon dioxide. Feedstocks utilized by researchers from the past decades include water hyacinth, wood chips, corn silage, food wastes, and sugarcane bagasse. Process parameters that influence the anaerobic digestion process include pH, temperature, organic loading rate, feedstock type, mixing, hydraulic retention time, and the carbon to nitrogen ratio. This paper reviews the scope of biogas production from the anaerobic digestion process and details the various parameters affecting the process. Copy
