According to AP, some hotels are taking those itsy soap pieces left behind by departed guests and sending them to a recycling plant. They’re melted together, sanitized and processed into fresh bars to be donated to families in poverty areas around the world.

A recent example is the Stonewall Resort in West Virginia. The hotel’s plan is to send the used soap to the nonprofit Global Soap Project processing center in Norcross, Ga. Global Soap Project representatives estimate that more than two million bars of guest-used soap are trashed every day by U.S. hotels.
