About 1 million bars of soap are tossed out daily by U.S. hotels, according to Clean the World, an Orlando-based nonprofit organization that recycles used and unused soap for distribution to developing nations and domestic homeless shelters. In time for Earth Day, Clean the World announced that it inked an agreement with Starwood Hotels to collect and recycle soaps, shampoos, conditioners, lotions and gels. The deal is Clean the World's first to cover an entire multi-brand hotel network.
