Paul speaks to Thor Retzlaff, a skier, mountaineer, adventurer and entrepreneur with a passion for changing the way we think about and deal with human waste, particularly in the outdoors. 

Inspired by a trip to Everest base camp in 2018, Thor and his team decided to launch Do Good Shit, a not-for-profit on a mission to reduce the harmful impacts of human waste, by delivering dignified and sustainable sanitation systems to ecologically sensitive environments and their surrounding communities. He's since gone on to co-found a revolution in portable toilets called Wasted

Paul and Thor discuss the golden rule of properly managing human waste in outdoor settings. They also talk about the hidden potential of urine and upcycling this liquid gold, as well as getting some insight into Thor's trip to build a toilet in the Himalayas and summit Ama Dablam.
