"Gobar is the Nepali word for cow dung. The “Gas” refers to biogas
derived from the natural decay of dung, other waste products, and any biomass. The gas is easily collected and stored for lighting, cooking and other household uses
. After bacteria digest the dung, the by-product is a rich organic fertilizer, sometimes called slurry, or bioslurry. That fertilizer is more effective than raw dung, with important benefits for hands-on farmers
. For instance, it doesn’t smell bad, and almost all the pathogens and weed seeds have been destroyed.
There is no downside. No waste. No poisonous residues or batteries. Few moving parts. Gobar Gas is an astonishingly elegant tap into “the circle of life” which environmentalists, economists, development people and humanitarians can all admire."
Dutch NGO SNV, which has been instrumental in bringing Biogas to developing countries in South East Asia and Africa
, is now looking at developing biogas in Afghanistan.
Michael Yon - "It’s important to consider the less easily monetized yet real benefits from using Gobar Gas. Saving 2,500 kilograms of trees per family each year has long-term economic value, and it keeps the birds and squirrels happy. Improved health from better sanitation and the absence of constant wood smoke in the home has clear economic benefits, as does the ability to send children, freed from the labor of searching for fuel, to school. These items, and many others, don’t fit on a balance sheet, but they improve conditions for real, long-term economic and social development. Health and education are the foundations of human capital needed to sustain a wealthier, more advanced society."
