CEE Environmental Engineering PhD student William Tarpeh discusses how access to a toilet can change the course of someone's life.
United Nations World Toilet Day is Tarpeh's chance to proselytize about all things sanitation. He tweets regularly about topics like toilets and international development.
In the lab, Tarpeh is using new technical processes to extract nitrogen from urine to create a nutrient-rich fertilizer. “From a technical perspective,” he says, “urine has a lot of interesting chemistry going on.”
Tarpeh's advisor is Professor Kara Nelson.
