Biogas is produced in a "no oxygen is present" environment or in an anaerobic environment, when certain bacteria decompose organic material. The whole process is referred to as anaerobic digestion (AD). AD effectively treats the organic fraction of waste which has many benefits. The process not only leads to a healthy and clean environment, but also produces a renewable energy source like methane.
In a biogas plant, biomass like vegetable wastes, animal excreta, and weeds undergo decomposition in the absence of oxygen and form a mixture of gases. This mixture is the biogas which is used as a fuel for cooking and lighting.Application Areas:
