The closed-system Blue Diversion toilet is designed for off-grid use
Two years ago, an off-grid closed-system toilet known as the Diversion won an award at the Bill & Melinda Gates Foundation's "Reinventing the Toilet" fair. Created by the Swiss Federal Institute of Aquatic Science and Technology (Eawag) and now called the Blue Diversion, it recently also won the title of Most Innovative Project (Europe/West Asia), as bestowed by the International Water Association. So, what makes it so special? Well, for one thing, the same water that flushes it is subsequently used in its hand-washing sink.
