The situation of energy in the world today, whether in emerging or industrialized countries, is regularly discussed in economic, political, and technical terms. Meanwhile the main sources of energy like coal, natural gas, crude oil, and even nuclear energy are becoming scarce. Bioenergy is deriving more and more significance in terms of research and development.
Hence the technology of gasification to produce biogas is being researched throughout the world. At a gasification installation, the biofuel is first changed into an explosive gas. This "synthetic gas" is distilled and then converted into biogas with features similar to natural gas.
Biogas is an explosive gas that is brought forth from the anaerobic putrefaction of organic materials. Biogas consists of methane, which is a combustible material, and various other impurities like carbon dioxide and hydrogen sulfides. Hence biogas cannot be used in its raw form and has to be cleaned to remove impurities before it becomes usable.
Unique wells have to be bored in order to accurately get biogas out of a landfill. When designed properly, landfills will be a primary source of biogas for several years. This is the most efficient method of trapping all gas formed. Apart from this, biogas has practically no other toxic discharges when compared to fossil fuels.
