Many innovations in clean energy, including biogas, have demonstrated incredible applicability and success within communities here in Eastern Uganda. We have begun exploring the feasibility of bringing home biogas solutions to Buyobo and the surrounding villages for the following reasons!

Challenges surrounding today’s energy sources are increasing:

Homes in remote villages rely primarily on burning firewood to power stoves used for cooking. In some cases, homes have supplemental power from solar panels to fuel small lights. However, the environmental and humanitarian impacts of so many homes and villages using firewood are getting increasingly severe.

The challenges with this significant reliance on firewood include:

  • There is a diminishing supply of trees which can be chopped for wood (especially due to the logging companies)
  • Reduced foliage makes the land more susceptible to landslides (especially during the ~5 month rainy season) which have ruined homes, villages, roads, and bridges across the region as well as killing many people in their path
  • Villagers must travel increasingly farther away from their homes to source firewood, creating sometimes dangerous and lengthy treks through unfamiliar forests

Biogas is a potential solution:

In order to reduce the dependence on firewood, one option is for homes and villages to install biogas solutions in their homes. Biogas is fuel that is produced by fermenting organic matter, such as cow dung and household waste (process diagramed below1). Household systems are typically small outdoor structures with pipes that run underground into the home and rely on cow dung as the organic input.

In order to see biogas in action we visited Namisindwa a village on the other side of the mountain to see how their home systems were working for them! Below are some photos from our visit:

homeowners put the cow dung here and it will slowly make its way to down to start its change from dung to gas! Surprisingly it doesn’t smell.

A training school has also installed a biogas system to power their kitchen. They use a mix of human and cow waste

There are several international organizations involved in bringing biogas technology to Uganda. To learn more about these efforts, called the “Uganda Domestic Biogas Programme (UDBP),” please visit www.heifer.org and www.africabiogas.org.
