 Each year, the Sunrise Diner produces about 1,000 pounds of bacon grease that ends up in the trash. Sam realized that he could make soap out of the bacon grease just like his great-grandmother did. She started doing it during the Great Depression when the family couldn't afford soap and continued doing it until she died in 2006. It took a few months to get it right, with the only change being the addition of essential oils for scent. The revenue made from the Bumble Soap now covers 80% of the cost of the bacon used in the restaurant.
