What is biogas?

Biogas is a natural gas that mainly contains methane (CH4). Biogas is produced from bio-degradable waste, primarily animal and kitchen waste. A mixture of waste and water goes into a biogas digester. Waste bacteria inside the digester will produce gas. This biogas is channelled to households through a pipeline. The households can cook on the biogas making use of a gas stove connected to the pipeline.

Benefits of biogas

1. Environmental protection. When biogas is used to cook on less fuelwood will be used. This results in a reduction of greenhouse gas emissions and deforestation.
2. Emancipation of women. Women are collectors of fuelwood, take care of the children, cook, and often have to provide an income as well. It is estimated that women spend 2 to 3 hours per day on collecting fuelwood. With biogas they can use this time for all kind of activities to improve their position in the society instead.
3. Health. Many women and children have health problems that are related to inhalation of smoke from woodfires. Cooking on fuelwood in hardly ventilated kitchens is detrimental to their health. Cooking on gas does not expose them to smoke.
4. Fertiliser. The by-product of biogas production is so-called ‘slurry’. Slurry can generate income when it is sold as a fertiliser or increase agriculture production when it is used on the land.
5. Job-creation. Constructing and operating biogas digesters may create jobs for local people.
