BACKGROUND
[002] Generally, bio-gas is produced from the biomethanisation of animal wastes and home generated food waste,with the rapid increase in urbanizationin many parts of the developing world bio-gas plants built in rural areas are at a long distance from the main source of organic waste streamsi.e.from cities resulting in increasedtransport emissions from diesel trucks. In a conventional bio-gas plantthe organic feedstock is collectedin large domed anerobic digestersthat produce the bio-gas.These conventional plants require a large amount of space for plant establishment and theassociated plant construction cost is also high in terms of time and material usage.A stationary bio-gas plant once built cannotbe transported from one place to another place for producing the bio-gas. And can only process a fixed amount of organicfeedstock.

[003] In the light of aforementioned discussion there exists a need for a system and a method that would ameliorate or overcome the above mentioned disadvantages.
