Gaseous Bio-fuels

Biogas or methane is the main form of gaseous biofuels. Biogas is produced through methane digester system called anaerobic digester. It decomposes organic in fertilizer to simple organic gaseous compounds (Demirbas, 2008).Continuous feed digesters( feed a few each day for regular production) and patch load digesters( filled all at one time as production of gas reduces when it is emptied ) are the main two types of biogas digesters used to yield methane. People use both methods to get a better number of crops (Hoard & Hoard, 2008).

It is not difficult to make a bio-gas plant at home. Only little equipment is needed to be found. They are: two or three barrels with lids, retaining rings, manure, tubes and manifolds (made with pipe). First, manure is filled into the barrels and kept in exposure to sun to warm. The nature by itself does the gas producing process. Second, Barrels must be connected with the help of tubing and it should be gone through two manifolds to gather produced gas. Furthermore, this tubing system should be placed in a shed a little away from the barrels and other buildings and weather. This process is an eco-friendly procedure and cheap too. As it consists of a few steps, it is easy to install this system in remote areas where there is empty spaces or gardens of villagers. (Wickramasinghe, 2008)  

When using bio-gas technology for a domestic plant, we can use it as a good cooking fuel which combustions with oxygen properly. Moreover, it’s sufficient to save 70% - 90% consumption of firewood or other expensive cooking gases such as LP Gas. Also it reduces the carbon dioxide emission to the environment. When we use a well improved cooking stove, the productivity of bio-gas also increases as it has more space to react with oxygen in the normal air (Holandia Biotech, 2005). In addition, this domestic gas unit is simple, cheap and effortlessly expandable without any electricity for operation. This method also encourages maintaining large gardens and to save money, besides, it keeps the environment clean. Hence, anyone who has a little money with their land can implement a bio-gas plant and make their expenses at a low rate.
