Caltech – A Winning Sanitation Solution

An estimated 4.5 billion people in the developing world lack access to adequate sanitation facilities—a situation that contributes to millions of deaths every year as well as environmental pollution and economic losses. But even the best sanitation systems installed in the developing world can easily be rendered useless if they break down and no one in the area knows how to fix them.

That is the problem now being addressed by the inventors of the solar-powered toilet, a unit developed by a team led by Caltech’s Michael Hoffmann that won the Bill and Melinda Gates Foundation’s Reinvented Toilet Challenge in 2012. The toilet integrates an electrochemical reactor to treat wastewater, providing a safe and inexpensive way to dispose of human waste. Since developing the solar toilet system, the engineers have worked to improve its design and are field-testing several prototypes at university and public park settings in India and China (with plans to begin testing four additional units in schools in South Africa).
