Winners Announced

Thank you to everyone who contributed to the challenge and a massive congratulations to the winners below. This is a really special challenge for OpenIDEO and we're proud that the winning ideas and more will become part of a project deliverable that will help to move the concepts forward.

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.

Congratulations to all our contributors!

Contribution list

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: , ), 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 (, Adriana’s “Toilet Lid” inspiration (, and Jocelyn’s connecting comment.

This concept is directly inspired by Alessandro’s call to “imagine that people would not have to pay anything to use the bathroom, but that these bathrooms were small factories that produce gas and fertilizer”, as well as by the many other OpenIDEO contributions that I’ve linked to in the text and to the right. I will focus on trying to propose a framework that pays for poop and makes sustainable sense for the challenge’s focus area of Kumasi, Ghana.

Changing behavior, especially among adults, is a very tough thing to do. Given that, I suggest we think about how we can teach the youngest generations in areas like Kumasi to be responsible about their sanitation and waste disposal habits - after all, it's today's kids who will be running these communities very soon. And I think women and mothers are the perfect demographic and vehicle to deliver these kinds of messages.

In the same way that microfinance has leveraged group lending to ensure accountability and repayment, NGOs or even for-profit organizations can engage communities in "group buys" of toilets. Communities would pool together resources to apply for a 'toilet loan' and collectively repay that loan. If the group defaulted or didn't maintain the toilet correctly, everyone would lose free access to the toilet (the NGO or company could take over and turn the toilet into a regular public latrine).

Reward consistency of good cleaning service, and help both the service provider and their customers communicate that their facilities are Gold Medal clean.

Get a bucket, use a bucket, get a new bucket. What if people are rewarded with a clean, shiny, new-looking bucket each time they bring a full bucket to collection?
