Situation surrounding toilets in developing countries
In many developing countries including Malawi and Kenya, where NICCO has been working, people still mainly use a pit latrine, or open spaces to defecate, not having access to a sanitary toilet facility. In the rainy season, sewage spill causes infection and diarrhea, leading to the deaths of children with a particularly weak immune system.
Circulation System Using Eco-San Toilets
In our project sites, NICCO is working to promote ecological sanitation toilets, so-called "Eco-San Toilets".
Eco-San Toilets, due to their high-floored feature, prevent spilling of human excreta when raining, and thereby help prevent water pollution and soil contamination. Feces are dried and sanitized using ash as an alkaline additive in a tank for approximately six months, to use it as manure for the soil. Also, urine is collected separately from feces and diluted with water, so that it can be used as liquid fertilizer. These fertilizer and manure produced by Eco-San Toilets increase crop yields 1.2~2.5 times more than non-fertilized farm fields, and reduce the use of expensive chemical fertilizer.
1. Public health improvement
Workshop on Eco-San Toilets for children: NICCO educates them on proper usage of toilets, health and hygiene through these workshops.
2. Making rich soil for faming
Local people learning on Eco-San manure: Feces taken out of the tank is dry and can be used as organic manure.
3. Less use of chemical fertilizer
Cultivation comparison: Crops grow well even without chemical fertilizer, when applied Eco-San manure. (above) field without Eco-San manure, (below) field with Eco-San manure
Eating and elimination are basic human activities, and a part of natural cycle. We think it is important to make them safer and more hygienic through efforts such as promoting Eco-San Toilets, in order to help build a sanitary, prosperous village.
