The biogas is a product generated through the decomposition process of organic material by anaerobic bacteria. It is generally composed of 60% methane gas and 40% carbonic gas (CO2). It is comparable to natural gas, which is constituted at 99% methane gas. Biogas is a clean and renewable source of energy, able to replace natural gas to cook, produce heat, heat water, and generate electricity.
HOW TO PRODUCE BIOGAS?
To generate biogas, organic materials must be stored in a closed container, heated, and moved by what is called a digester. In this environment, the anaerobic bacteria feed on the organic materials, generating biogas.
ADVANTAGES OF BIOGAS
There are many well known advantages of biogas. The biogas eliminates any kind of smoke and ashes generated by the traditional stove. The women and their children are therefore less affected by some respiratory infections generated by the smoke and ashes and enjoy much safer environment. In rural communities, the stoves operating on the biogas concept enable the women to avoid the traditional collection of wood. This is statistically evaluated to 27 to 36 kg per week, and is quite time consuming.
The digested material generated after the fermentation is richer in nutritive content than animal fertilizer. Applied on the cultivation of fruits, vegetables, or other crops, it produces a quality fertilizer and guarantees more productive crops.
The process of the anaerobic digestion destroys pathogen bacteria, resulting in hygiene that is considerably improved.
