One of the most humiliating realities for Middle Eastern refugees involves a basic human need: going to the bathroom. At camps like Zaatari in Jordan, people walk miles and wait in endless lines to use unsanitary facilities, raising the possibility of disease.
The indignity is particularly crushing for girls and young women, who risk being attacked using communal toilets late at night. Others simply try not to go, contracting urinary tract infections.
In response, some refugees have resorted to simply digging pits in the ground and trying to drain the sewage through trenches. It’s a grave sanitary hazard that affects more than two billion people worldwide.
Cambridge, Mass.-based change:WATER Labs plans to bring dignified sanitation to this population by developing a compact, evaporative toilet for homes without power or plumbing. Because sewage is mostly water, it’s possible to rapidly vaporize it, eliminating up to 95 percent of daily sewage volumes.
The toilet has a polymer material that functions as a sponge, soaking up liquid water, released as water vapor into the air; it also contains residual waste, preventing pollution. Residue would be collected once or twice per month.Co-founder Diana Yousef, a biochemist and a research associate with MIT's D-Lab, says her team will build their first prototype in the next several months, using a pilot partner in the Middle East who has offered one of its refugee shelters as a test site. She says the project could be transformative for refugees, especially young girls. The team is gearing up to participate in the Hult Prize regional social entrepreneurship competition in March. This year’s theme is “Reawakening Human Potential,” and the winner receives $1 million toward their project. change:Water Labs won the MIT qualifier round of the competition in December.
Team member Conor Smith, MBA ’18, credits his experience at MIT helping to develop his innovative mentality.
“When I came to MIT, I knew that the entrepreneurship programs were well-known and strong, but the resources at Sloan and the greater MIT community have been even better and more plentiful than I expected. In many ways, it has inspired my own endeavors and provided the connections to entrepreneurs with whom I’ve been able to bounce ideas around, seek advice, and collaborate,” Smith said.
The change:Water Labs team hopes that refugee camps are just the beginning.
“Safe sanitation for all is a motto and mission of the organization. Initially, we’re focusing on refugee camps like Zaatari, where lack of affordable toilets have turned these camps into massive cesspools. And beyond the camps, there is incredible potential to apply this solution to the more than a billion non-sewered households around the world,” Smith said.
