In India, the area available for the storage of day-by-day increasing amount of municipal solid wastes is depleting. The most
important fact is that several types of organic matters, abundantly found in these municipal wastes leach down to ground water
and badly affect the human kind, animals and plants by causing several dreaded diseases. The gases, such as methane, nitrogen
dioxide, etc., generating from the municipal solid wastes are also directly or indirectly responsible for the global warming. All
the above-mentioned problems have attracted the attention of scientists and environmentalists on a global scale to achieve the
environmental and health security. The gainful and environment friendly utilization of municipal solid wastes and obtaining
the economical products and production of cleaner energy therefrom not only ensures the economic development of the country,
but also proves to be a harbinger of the microbial technique for the municipal solid waste treatment. Anaerobic digestion of
solid organic wastes, especially municipal solid wastes is proved to be very important for the gainful utilization of municipal
solid wastes, In the process of anaerobic digestion, organic matters are digested in the absence of oxygen, in which biogas
(which is a mixture of 65% methane and 35% carbon dioxide), besides a little amount of microbial biomass is obtained,
Therefore, a good amount of gaseous fuel can be obtained by the microbial technique, which is beneficial from two points of
view, Firstly, it makes the municipal solid wastes lesser polluted and secondly bio-energy is produced, which can be used for
vehicles and also as heat. The present paper focuses on the anaerobic digestion of municipal solid wastes for the production of
bio-energy, such as methane and methanol which can be used as a fuel.
