Biogas is a good clean alternative that reduces waste while producing cooking fuel as well as manure for farms, reducing dependency on imported petroleum and fertiliser.

Given its successes in household biogas plants, Nepal has used farm waste energy in a mass scale. Twenty years later, there are industrial-scale biogas plants but much more investment is required. 

Biogas is a good clean alternative that reduces waste while producing cooking fuel as well as manure for farms, reducing dependency on imported petroleum and fertiliser.

Excerpts from a Nepali Times report published on issue #166 17-23 October 2003:

The first experiments with biogas in Nepal took place in the 1950s, using the Indian drum design. But the rusty drums needed expensive maintenance and the above-ground design was also unsuitable for Nepal's colder climate. In 1979, Nepali scientists modified the Chinese underground design with an air-tight dome and produced a cheap and easy-to-make prototype that worked beautifully. There are virtually no moving parts, and the underground digester keeps the slurry insulated from the cold.

Nepal's biogas campaign really took off after 1992, when the Biogas Support Program (BSP) began to subsidise farmers who had to take out a soft loan to finance the construction of the plants. 

BSP engineers are currently experimenting with biogas plants that can work in even colder regions in high-altitude villages where deforestation is rampant.

Even though biogas plants produce methane, which is a powerful greenhouse gas, most of it is burnt and its volume is negligible compared to emissions from fossile-fuel burning cars.
