hello Sir
Biogas production is a waste management strategy and its introduction should be part of a larger Integrated Solid Waste/Resource Management (ISWM) strategy.
Biogas is a fuel gas mixture, has come to the forefront globally due to a growing interest in its capacity as a viable fossil fuel substitute. It has an emerging formidable reputation due to the range of environmental, social and economic benefits its usage yields.
The advantages of biogas have been acknowledged by the government and so the fuel source has been included as a potential alternative within the Framework.
Biogas is a fuel gas mixture, composed typically of 55-70% methane, 30-45% of carbon dioxide and 200-4000 ppm by volume of hydrogen sulphide as well as other gases in small quantities.
It is produced under natural conditions during a process called biomethanation, where organic material undergoes anaerobic decomposition. Anaerobic digestion occurs naturally and uncontrolled at landfills and under strict conditions the gas produced is termed landfill gas (LFG).
There are multiple uses of biogas but when applied for vehicular use (as is suggested for this case), it is upgraded using a compression and storage technology similar to compressed natural gas (CNG).
During this procedure the CO2 is removed to produce biomethane, which has a methane content of 96 - 97 % volume, while impurities like sulphur, water and other particles which can impair engine functioning are also eliminated.
