Perhaps he noticed because his father was a soapmaker in Uganda. When Derreck Kayongo learned how much soap was thrown away by hoteliers in the US, and that 2 million children die each year due to a lack of sanitation, he decided to do something about it. He started Global Soap Project. Volunteers across the U.S. collect the hotel soaps and ship them to the group's warehouse in Atlanta. On Saturdays, Atlanta volunteers assemble there to clean, reprocess and package the bars. Then, they work with partner organizations to ship and distribute the soap directly to people who need it -- for free. To date, more than 100,000 bars have been gifted to communities in nine countries.
