The PeePoo is a brilliant project that addresses existing “flying toilet” behaviors through a single-use sanitizing toilet bag that improves hygiene and creates fertilizer. As the project has been field testing (well worth a look: http://www.peepoople.com/pdf/GTZ_toilet%20bag.pdf , http://www.peepoople.com/pdf/Peepoo.Impact.Assessment.Report.pdf ), there’s likely to be iterative improvements over time. This concept envisions an “upgrade” to the PeePoo that 1) PeePoo users could trade-up to or start off with directly if funds allow, and 2) Bucket Latrine/Chamber Pot/Public Toilet users could switch to for a similar cost. It very much builds upon Jeff’s “PeePoo Bag” inspiration (http://bit.ly/ccACaG), Adriana’s “Toilet Lid” inspiration (http://bit.ly/c6kNIo), and Jocelyn’s connecting comment.
There's some nice overlap in the ideas that the IDEO team created in parallel, but perhaps the most valuable addition to the project is how the OpenIDEO community generated ideas that expanded the scope of the larger issue of low cost sanitation needs. Ideas that addressed issues like community awareness and funding help to make the team's product and service concepts more robust and realistic.
