Today I attended the Reinvent the Toilet Fair— a fascinating learning experience and an important step in providing safe sanitation for everyone in the world.
A year ago, the foundation launched an initiative to tackle the problem of sanitation in the developing world. We called it the Reinvent the Toilet Challenge. In this photo gallery you can learn more about each of the grantees and their sanitation solutions.
This week in Seattle, the foundation is holding a Reinvent the Toilet Fair. Today I awarded prizes to three universities who responded to our challenge a year ago to come up with solutions for capturing and processing human waste and transforming it into useful resources.
The winners included:
- first place to California Institute of Technology in the United States for designing a solar-powered toilet that generates hydrogen and electricity,
- second place to Loughborough University in the United Kingdom for a toilet that produces biological charcoal, minerals, and clean water, and
- third place to University of Toronto in Canada for a toilet that sanitizes feces and urine and recovers resources and clean water.
A special recognition was awarded to Eawag (Swiss Federal Institute of Aquatic Science and Technology) and EOOS for their outstanding design of a toilet user-interface.
