Talk by Prithvi Simha and Gert van der Merwe on “Recycling resources excreted in wastewater”

  • 5 October 2023

Join us for a talk on 12 October 2023 at 19h00.

Recycling resources excreted in wastewater can contribute to achieving a sustainable future and circular economy in the sanitation space. Such recycling could reduce human transgression of several planetary boundaries, including those on global flows of nitrogen and phosphorus. This talk will explore how the water and sanitation sector can make such a transition towards circularity. We will introduce the concept of “source separation of wastewater” and explore the technologies that can be used to safely collect, treat and recover valuable resources excreted in source-separated human urine. We will also look at case studies from Sweden where such technologies have been implemented. Lastly, we will consider ways and strategies for introducing new sanitation technologies and behaviours in society.

Prithvi Simha, Ph.D. is a Researcher in Environmental Engineering at the Swedish University of Agricultural Sciences. His work focuses on developing novel technologies to safely recover and recycle resources from different types of wastewater. As co-founder and CTO of the company Sanitation360, he also implements these technologies in real world settings across the world.

Gert van der Merwe grew up in Namibia before moving to South Africa where he graduated from the University of Pretoria (MProf. Arch.)  in 2014 where he taught at the University of Pretoria and worked in practice until 2020. He then returned to Namibia where he currently teaches at the Namibia University of Science and Technology. He is currently pursuing a PhD at TU Delft. His PhD research focuses on water as a lens to shape norms and values to develop non-anthropocentric theory with the preliminary title Water: Flow, Code and Stock - a rhizomatic genealogy of the Political Ecology in Namibia.
