Case van Genuchten turns arsenic waste into a valuable raw material (he's an environmental engineer)

Case was a regular California kid: he skateboarded, he surfed, and he also liked math. He tried a few different majors in college, but finally found his calling: environmental engineering. He went to graduate school, and a lucky encounter during the first week changed his whole life.Case van Genuchten, PhD, now works for the Geological Survey of Denmark and Greenland (GEUS) and just published research showing that arsenic from drinking water waste can be changed into a valuable commodity. He has studied how to remove arsenic from drinking water for years, but now, in this new paper in Science Advances, he has figured out how to turn arsenic waste into metallic arsenic, a raw material important for digital infrastructure and clean energy systems. Decrees in the EU and US over the past few years have declared metallic arsenic a Critical Raw Material, making his research even more important.To see a beautiful video on Case's work, check out "King of Poison," from the Underground Channel.
