it showcased the innovative toilets invented by eight universities funded by it in 2011 and used 50 gallons of fake feces made from rice and soybeans to treat them. On August 12, 2012, researchers from the Swiss Federal Institute of Fisheries Science and Technology (Eawag) installed their designed toilet at the Seattle Innovation Toilet Expo.　　　　 3.　　　　 8.5 million children under 5 to die every year.　　　　 On August 12, 2012, researchers from the National University of Singapore presented their work at the Innovative Toilet Expo in Seattle. These prizes will be used for continued research on innovative toilets.　　　　

6. As part of the 'ReinventtheToilet Challenge', the Gates Foundation in 2011 provided a grant of US$400,000 to eight universities around the world to invent safe, affordable, and hygienic waterless toilets. 2. Environmental sanitation may not be a more attractive issue, but it is a big problem in many parts of the world. This kind of toilet can convert human waste into biochar through pyrolysis.On November 26, Beijing time, the Gates Foundation recently held an innovative toilet exhibition in Seattle, the United States, to showcase the global innovative toilet research results funded by the foundation and tested these toilets.　　　　

4. In order to find solutions to global health problems, the Gates Foundation has funded many research institutions around the world to conduct research on innovative toilets. The second prize of 　　　　 (US$60,000) was awarded to the 'Toilet that Produces Biological Charcoal, Minerals, and Cleanwater' from Loughborough University, UK.

The feces in the toilet will be mixed under the action of machinery and eventually become plant fertilizer. This type of toilet can use biochar to dry and burn feces, and use the heat generated by the combustion to extract water from the urine.　　　　 5. Tested. After the expo, the Gates Foundation awarded prizes to the Dual Function Soft Hand Held Sprayer inventors of three of the more promising innovative toilets
