From my old home town of Kitale, Bio-latrines in Kenya use the "yellow" and the "brown".
"In Kitale, Kenya, 14 schools are facing closure. Not because of governmental reforms, lack of funds or a shortage of resources - but because of their sanitation. And yet a gift of just £50 could be enough to help keep a school open.
But there is an answer which would help rescue these schools from closure.
As little as 6,750 Kenyan shillings - just £50 - can help to build bio-latrines. Because they are a "dry" toilet, they neither require water to work (which is already scarce) nor is there any danger of waste leaching into the groundwater and polluting water supplies, causing disease.
The bio-latrine system also brings with it a surprising and marvellous range of added benefits, including helping to both heat and light the school."
