Christoph Lüthi sees a renewable, locally produced and growing resource where others see only human waste.
Watch his talk to learn why shit matters! Christoph Lüthi heads the Sanitation, Water and Solid Waste for Development (Sandec) department of the Swiss Federal Institute of Aquatic Science and Technology (Eawag).
He gets inspired from field visits to the slums of Africa and Asia, and practices what he preaches, by supplementing his urban garden in Zurich with fertiliser produced from the urine of his Eawag employees! This talk was given at a TEDx event using the TED conference format but independently organized by a local community.
