Rabbi encourages biodiesel industry to produce kosher for glycerin market

In Wisconsin, a rabbi speaking at the National Advanced Biofuels Conference & Expo in Milwaukee encouraged biodiesel producers using corn oil, soy and oil vegetable oils as feedstocks to ensure their production method was kosher, providing wider market opportunities for the glycerin byproduct. Some polysorbate 80 used in the corn oil extraction process can be either vegetable or animal-based, for example, so only the vegetable version is kosher. Companies like Proctor & Gamble, Cargill and Archer Daniels Midland already produce kosher glycerin.
