(CNN)Next time you check out of a hotel, spare a thought for the barely touched bar of soap left behind in your room.
Around the world, five million hotel soaps make their way to landfills every single day.
But Clean the World aims turn those discarded slabs into a life-changing commodity.
With recycling centers in the United States and Hong Kong, the not-for-profit corporation has partnered with 5,000 hotels internationally to recycle soap from nearly one million hotel rooms daily, distributing them instead to families, schools and organizations in need.
Why? UNICEF estimates that 1.4 million children a year die from diseases such as pneumonia and cholera, easily preventable with better hygiene.
"Soap and health and hygiene have a huge impact in our world," founder Shawn Seipler tells CNN.
"Soap impacts health. Soap impacts one's environment. Soap impacts economic issues. Soap impacts the rate at which infectious disease spreads."
