📰 Circular management of human excreta as a pillar of sustainable cities and food systems

https://hal.science/hal-05478504

This is the written summary of a presentation I gave at the annual meeting of the International Fertiliser Society (you can watch the presentation here: https://video.ploud.fr/w/qb3a8rXPxW7QQmWN7uBBKS)

I discuss the limitations of sewer-based sanitation in the face of climate change and increasing water scarcity: can we still afford the amount of water that is needed for sewers to effectively carry fecal matter all the way to the treatment plant?
Obviously I also mention how alternative management methods are being tested throughout Europe, including in large neighborhoods in Hamburg, Sneek, or Helsingborg (and soon Paris).
