A prototype of a toilet (exhibit 19), designed by Eawag: Swiss Federal Institute of Aquatic Science and Technology and EOOS of Switzerland, that diverts waste and water for safe sanitation at the
Reinvent the Toilet Fair in Seattle on August 12, 2012. The model diverts urine and recovers water for flushing. The urine and feces will be safely transported to a decentralized processing center. The water used for cleaning will be recycled by a gravity-driven
biological membrane.
