Hygienic sanitation facilities are crucial for public health. Inadequate sanitation is a major cause of disease worldwide and improving sanitation is known to have a significant beneficial impact on health, both in households and across communities. Some 842,000 people in low- and middle-income countries die each year because of inadequate water, sanitation, and hygiene. Inadequate sanitation is estimated to cause 280,000 diarrhoeal deaths annually and is a major factor in several neglected tropical diseases, including intestinal worms, schistosomiasis, and trachoma.
In East Africa, many schools in rural areas lack enough hygiene and sanitation facilities, and most schools are dependent on wood and charcoal as fuel for cooking, often burned in open fires or poorly functioning stoves and causing health problems for the people involved. The aim of this project was to improve the living conditions of school children in Tanzania by providing safe and financially viable sanitation systems combined with biogas and fertilizer production to schools.
The bio-sanitation system developed by Simgas is an integrated solution that sanitises human waste while producing biogas. For the schools, the bio sanitation systems reduce the costs of disposing toilet and other organic waste, and of fuel for cooking; reduce soot and carbon emissions and improve the air condition in the kitchen; improve school crop production; improve hygiene, and contribute to a healthier and modern school. Additionally, when the bio sanitation systems are used for education purposes, it contributes to increased awareness about renewable energy and biogas technology.
The project included a research and development design phase, a field trial, and testing for 11 government schools in Kilimanjaro Region to provide a bio-sanitation solution that is affordable, easy to install, and scalable.
By adjust 2018
- Access to sanitation facilities with waste treatment had been provided to around 4,750 students and 166 school staff in 12 schools.
- Generally, feedback from the cooks using the gas was very positive. Users reported benefits including reduced fire preparation time and effort, shorter cooking time, and less indoor pollution.
