The gas produced by decomposition of agriculture waste, molasses (remains of sugarcane), other vegetation, dung and human excreta is called biogas. It mainly contains methane, methane is an inflammable gas which is primarily used for cooking. After extracting biogas, the material that remains behind in the biogas pit is used as an excellent natural fertilizer. We can keep our villages clean by producing biogas and also obtain natural fertilizer. In India, Uttar Pradesh stands first in biogas production, Gujarat ranks second.
The largest biogas plant of Gujarat has been installed at Methan village near Siddhpur in Patan district. This plant runs with co-operation of villagers. Other bio-gas plants in operation are located at Rudratal of Daskroi taluka of Ahmedabad and at Dantiwada in Banaskantha districts. People have also started setting up plants that are operated individually or collectively.
