If we can convert livestock manure to energy, why not convert human faeces to energy as well? And, if we can do it for households, why not for schools? More than 70,000 boarding schools in East Africa struggle to provide sufficient sanitation conditions for their teachers and pupils. Consequently, the unhygienic conditions cause children to become ill and stay home from school. SimGas is developing a safe bio-sanitation system to improve health and hygiene for schools and institutions.

The specific objectives of the project are:

  1. Improving access to safe sanitation for schoolchildren in rural Tanzania and Kenya and reducing the spread of diseases in schools;
  2. Developing a sanitation infrastructure at the schools, including safe human waste treatment;
  3. Replacing fuel such as wood and charcoal for cooking purpose by clean biogas, which reduces cost and improves the indoor environment;
  4. Increasing crop yield by applying safe and organic biogas-slurry and replacing/reducing expensive chemical fertilizer.

The goal is to improve the living conditions of school children in Kenya and Tanzania by providing safe and financial viable bio-sanitation systems with biogas and fertiliser production.

It all started when our partners WASTE and K-Rep bank discussed the possibilities to solve sanitation problems at Kenyan schools. They soon brought SimGas to the table to develop a product that would not only provide safe sanitation, but would also supply the schools with biogas for cooking and organic fertiliser for on-school crop production.


Since February 2015, that’s exactly what we’re doing. During the past months we’ve been busy installing 5 different, custom-made sanitation solutions at 5 schools in Kenya and Tanzania. The first school has started cooking on the biogas generated from their own toilet waste! Want to know more about our sanitation project? Contact Geert.
