OK....with al the press about the VW diesel scandal out there, and since it is Fryeday, I thought I'd ask the list a question, or perhaps a confirmation.  Someone here must know this stuff.
Is it true that bio-diesel doesn't emit the same noxious emissions as does the petro-diesel?
When I say bio-diesel, I am just referring to diesel created from "fresh" veggie oil, not the retreaded cooking oil variety.  Let's say it is fuel created from algae, canola, peanut, sunflower, soybean etc., sometimes referred to as SVO, or straight vegetable oil.
