Think biofuel is just for powering greener-than-thou granola mobiles? Actually, it can be used to make some pretty great soap. Marshall Dostal (who makes the soap) picks up used vegetable oil from some of the finest restaurants in LA and then processes it in his garage. The biofuel goes into your car and the glycerin goes into their soap and then Marshall takes the soap back to the restaurants that provided the oil and there you have it. A lovely little sustainable circle. $18.50, Ron Robinson.
