Who knew something so greasy could be so clean? The company Further uses waste grease collected from restaurants in the greater Los Angeles area to make hand soap. The by-product of waste grease is glycerin, which is the main ingredient found in liquid soaps. Further mixes the recycled glycerin with essential oils like bergamot and olive and exotic grasses to make great-smelling, green soap. And the company takes their eco-commitment -- um, further -- by using recycled plastic packaging, too.
