Atlanta (CNN) - That bar of soap you used once or twice during your last hotel stay might now be helping poor children fight disease.
Derreck Kayongo and his Atlanta-based Global Soap Project collect used hotel soap from across the United States. Instead of ending up in landfills, the soaps are cleaned and reprocessed for shipment to impoverished nations such as Haiti, Uganda, Kenya and Swaziland.
"I was shocked just to know how much (soap) at the end of the day was thrown away," Kayongo said. Each year, hundreds of millions of soap bars are discarded in North America alone. "Are we really throwing away that much soap at the expense of other people who don't have anything? It just doesn't sound right."
Kayongo, a Uganda native, thought of the idea in the early 1990s, when he first arrived to the U.S. and stayed at a hotel in Philadelphia, Pennsylvania. He noticed that his bathroom was replenished with new soap bars every day, even though they were only slightly used.
"I tried to return the new soap to the concierge since I thought they were charging me for it," Kayongo said. "When I was told it was just hotel policy to provide new soap every day, I couldn't believe it."
