Biogas

Biogas refers to a mixture of different gases produced by the breakdown of organic matter in the absence of oxygen. Biogas can be produced from raw materials such as agricultural waste, manure, plant material, sewage and food waste. It is a renewable energy source and in many cases exerts a very small carbon footprint.

Biogas is primarily methane (CH4) and carbon dioxide (CO2) and may have small amounts of hydrogen sulfide (H2S), moisture and siloxanes.This energy release allows Biogas to be used as a fuel; it can be used for any heating purpose and cooking.

To build a family type Biogas plant, a 12 ft by 8 ft of land is required. Once constructed, the lifespan of a Biogas plant is approximately 25 years. Biogas plants are easy to use and the maintenance is quite simple. The minimum cost for building a Biogas plant is between Rs 20,000 to Rs 23,000/-. This amount may, however, vary from place to place. The Government also provides subsidies for building a Biogas plant.

A nutrient-rich natural manure is obtained from the slurry generated by the Biogas plant. The wet slurry waste can be directly used as manure in the fields. The slurry can be dried and powdered and stored for use later in the fields.
