November 6, 2018 -- Bill Gates stellte neue Methode zur Sterilisation von menschlichem Abfall bei der Neu-erfundenen Toiletten Expo in Peking vor. Eine Methode, die der Philantrop und Milliardär bevorzugte, ist Caltech's
selbständige Haustoilette und Schmutzwasser-Reinigungssystem – jüngster Sieger der "Neuerfindung der Toiletten-Herausforderung".

The Bill & Melinda Gates Foundation has spent $200 million over the last seven years, funding sanitation research projects, including 20 toilet and sludge-processing designs that convert human waste into clean water and fertiliser.

Gates finds one approach from the California Institute of Technology particularly interesting. It’s an electrochemical reactor which can break down water and human waste into fertiliser and hydrogen – which in turn can can be stored in fuel cells as energy.

For every dollar invested in sanitation, about $5.50 is returned to the global economiy, according to the World Health Organisation.
