Biogas containing approximately 60% methane can be produced from paddy straw -a lingocellulosic waste, by anaerobic fermentation using cattle dung as source of inoculum .The total gas production from the paddy straw is more in comparison to that of cattle dung as substrate. But pretreatment of paddy straw with NaOH can reduce the Holding Retention Time significantly. Moreover paddy straw is able to supply higher yield of biogas due to its slow decomposition .The digested slurry was found to be a very good source of manure. Biogas containing 60% ....etc

Biogas Generation and its Utililities



.Typically 55% methane (CH4)45% carbon dioxide (CO2)H2S and H2O and trace gases
.Energy comes from methane only
.Energy value of methane 37.78MJ/Nm3
.Energy value of biogas 21MJ/Nm3

Anaerobic digestion technology 

In the absence of dissolved oxygen, anaerobic microorganisms will tend to ferment biodegradable matter to carbon dioxide and methane which can be collected and use as a fuel. This process is called ....etc

1. Abstract
Biogas is a clean environment friendly fuel. Raw biogas contains about 55–65% methane (CH4), 30–45% carbon dioxide (CO2), traces of hydrogen sulfide (H2S) and fractions of water vapors. Presently, it can be used only at the place where it is produced. There is a great need to make biogas transportable. This can be done by compressing the gas in cylinders which is possible only after removing its CO2, H2S and water vapor components. Pilot level trials to compress the biogas have been carried ....etc

Abstract
Biogas technology, besides supplying
energy and manure, provides an excellent opportunity
for mitigation of greenhouse gas (GHG)
emission and reducing global warming through
substituting firewood for cooking, kerosene for
lighting and cooking and chemical fertilizers. A
study was undertaken to calculate (1) global
warming mitigation potential (GMP) and thereby
earning carbon credit of a family size biogas plant
in India, (2) GMP of the existing and target biogas
plants in the country and (3) atmos ....etc
