3 billion people worldwide live in cities without sewers or wastewater treatment plant infrastructure. This forces them to dump their waste into open waters, contaminating the drinking water for others downstream. Imagine if we could harness nutrients in wastewater instead of harming human and environmental health. 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!
