Abstract
Methane is a colorless and odorless gas that occurs abundantly in nature as a product of certain human activities. Methane (CH4) is the simplest member of the paraffin series of hydrocarbons and is among the most potent of the greenhouse gases. With the increase of energy consumption and wastes generation due to human activities, anaerobic digestion, a technology which turns wastes into bioenergy, is receiving more and more attention in the world (Laiq et al., 2019). Biogas is produced during the degradation of organic matters by microorganisms in an anoxic environment, which is commonly referred to as an anaerobic digestion (AD) process (Christy et al 2014). Typically, this process involves the production of biogas mixtures which mainly consists of CH4, CO2, and traces of other gases such as H2, NH3 and H2S (depending on the source of the organic and inorganic matter being used). Many studies have reported that various types of organic waste materials such as animal and livestock waste/manure, food waste, organic municipal solid waste (MSW industrial waste, sewage sludge, and agricultural residues could potentially be used as economical sources to produce biogas (Yong et al., 2015).
