Gmoke writes, "Pure Home Water (PHW), the same people who make AfriClay Filters -- a locally-sourced clay pot water filter -- in Taha, Ghana are now building toilet blocks for local schools. In June 2013, PHW built a 6-stall toilet block in 30 days for a school in the village of Taha. They are planning to build the same toilet block for the neighboring village of Gbalahi and are looking for $8,600 over the next two months."
Toilets for Schools - Improving Sanitation in Ghana
PeePoo bags are alternatives to the "flying toilets" (plastic bags filled with human shit and then flung into the public street) used in Nairobi shantytowns. Created by the company PooPeople, they're lined with a thin gauze layer filled with urea powder, which neutralizes the bacteria in human feces. Once filled, the bags turn the poop into fertilizer, then biodegrade.
The Peepoo is in the form of a slim elongated bag measuring 14 x 38 centimeters.
Within the bag there is a thin gauze layer measuring 26 x 24 cm. The Peepoo is filled with urea powder. Without sacrificing ergonomic function, the bag’s design is adapted in every way so that it might be manufactured at as low a price as possible and sold to groups with the weakest purchasing power in the world.
The Peepoo is easy to carry and easy to use. It doesn't need any supporting structure, but, for convenience, a small bucket can help a lot.
