The concept of bio gas as a source of energy has been around since the early 17th century. Biogas is produced from waste materials such as animal manure, sewage, plant material, and crops. Biogas can be used for heating while cooking, gas for motor vehicles, power for electricity etc. With effective Biogas systems, the waste materials can be disposed of efficiently without any odor or flies. The digested slurry from the bio-gas unit can be used as organic manure in the garden. The usage of worm farms to decompose small garbage and waste composting for private residences is gaining popularity as a way to contribute to the environment.
The growth in the usage of gas-fueled vehicles around the world has been substantial, particularly in Europe. In the United States, biogas is quickly becoming a popular source of energy and a wide variety of feedstock is being tested. It has been estimated that the methane biogases derived from cattle, pigs, and chickens could be used to power millions of homes around the world. In Pakistan and India, biogas produced from the anaerobic digestion of manure in small-scale digestion facilities is called ‘gobar gas’.
There are many environmental benefits of using bio-gas as it reduces our carbon footprint and lessens the dependency on oil. The major components of the bio-gas plant are a digester tank, an inlet for feeding the kitchen waste, gas holder tank, an outlet for the digested slurry and the gas delivery system for taking out and utilizing the produced gas. The compost plant has to be filled every day with a mixture of food waste and water and thus daily kitchen wastes can be decomposed. Biogas is easy to set up and requires little capital investment and also it is a cheaper technology. Small scale Bio-gas digester machines are available for private residences.
