Abstract
Presently, Indian agriculture is facing the problem of not only the shortage of fertilizers but also of organic manure due to a large scale burning of animal dung as fuel. Another problem which is faced by the farmers is the inadequacy of fuel. Firewood is becoming scarceness expensive. Cattle dung cakes are the main source of fuel in rural India. In Haryana too, dung cakes, firewood and plant stalks fulfill the major part of the fuel demands of rural households. However, during of dung cakes is a national waste of valuable organic manure which can improve soil fertility·) Biogas plants can provide both fuel and manure. Biogas is obtained through the anaerobic fermentation of cattle dung. It contains 55 per cent of methane and 45 per cent of carbon dioxide. It is an excellent fuel and burns without smoke. Biogas can be used for cooking, heating, lighting and running of engines. This gives more than 60 per cent of thermal efficiency for gas as against only 11 per cent by burning dung cakes. The manure so obtained contains more nutrients than farm-yard manure which is odorless and easy to apply on the fields. Thus, a Biogas plant provides gas as fuel and enriched manure from the same quantity of dung
