Nat Geo Explorer: Ashley Murray

Ashley Murray is working to turn human waste in Ghana into profits. But Murray isn't working as a wastewater engineer in the country for her own financial gain. Rather, she has founded a company that helps bring money back into the country's sanitation sector by running individual businesses that collect and reuse human waste. Murray's company also collaborates with research organizations that are looking for ways to turn the waste into industrial fuel. Ultimately, some of the profits from this reuse of waste go back into providing sanitation for the poor.
