Further soap products are derived from making biofuel. Marshall picks up used vegetable oil from some of the nation’s finest restaurants and then processes it in our warehouse. The biofuel goes into our cars and the glycerin goes into our glycerin soap. Then we take our natural soap back to the restaurants that provided the oil and voila - a perfect, sustainable circle.
