Here’s how four soap factories create their products. Dr. Bronner’s Magic Soaps has a factory in Vista, California, where it can make 14.3 million bottles of its pure castile soap a year. All of its soaps are made with sustainable and ethical farming practices. Primal Elements has a factory in Huntington Beach, California, where it can make over 7,000 colorful soap bars a day, most of which have a design in the center. Nablus Soap Company is one of the last factories making olive-oil soap in the West Bank. The company follows a centuries-old Palestinian tradition, making its soap with only three ingredients: olive oil, baking soda, and water. Clean the World is a nonprofit organization that helps hotels donate and recycle sterilized soaps to people in need in 127 countries. The company partners with 8,000 hotels and resorts, including Hilton, Marriott, and Walt Disney World Resorts, to collect used soaps, sterilize them, and donate the new soap bars. The nonprofit has been able to donate over 50 million bars of soap since 2009.
