"Nairobi, Kenya," a photo from Boing Boing reader Biketripper shared in the BB Flickr Pool. On the bikeflaps of one rider, "A Strong Enemy Is Better Than a Weak Friend."
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.
