Photo: Autarky, Eawag - For three months, an extended family in South Africa tested the standalone Autarky toilet cubicle. Everyone was very happy with the quiet hideout. "I am really proud of our technology and can see huge potential in it", says Eva Reynaert, who was involved in the project and was one of the advisors during the field testing. The Blue Diversion Autarky toilet offers great advantages, particularly to less-developed regions of the world: It works without a water mains connection and does not need a sewerage connection either. By separating out grey water, urine and faeces, valuable resources such as water and fertiliser nutrients can be recovered.
