Bella Bargain: Wash Your Hands With "Grease" on Earth Day

by POPSUGAR Beauty 7

You've probably heard that restaurant grease can be transformed into bio-diesel fuel, and now, a clever couple has added another layer to this concept by turning byproducts of that fuel into a hand soap. Intrigued?

The waste grease is obtained from the kitchens of Los Angeles restaurants. It's then distilled for car usage, resulting in glycerin, a perfect ingredient in making soap. Hence, Further Soap ($18.50) was born.

If you'd like to try this unique soap, which is scented with bergamot, olive, and exotic grasses, now's your perfect opportunity. On Earth Day, — that's today — if you purchase one bottle of Further Soap, you'll get one free. Perfect for the penny-pinching tree hugger in your life.
