One night at a hotel in 2009, tech executive Shawn Seipler thought about how many bars of soap guests use for a night and then leave. He called the front desk to find out what they did with the used soap and learned that they just throw it away. In the U.S. alone, hotels throw out about 3.3 million bars of soap every day.
