Does one need special permits to make biodiesel?
This depends on how much biodiesel you intend to make. A test tube full would not turn the heads of most county inspectors. But a 500-gallon batch in your back yard might warrant a good review of local policy regarding the temporary storage and use of used vegetable oil, methanol, and lye. If you want to sell biodiesel, you do need permits and you will need to charge sales tax. For more information on selling biodiesel, Randall vonWedel has offered to give advice to anyone wishing to sell biodiesel, you can contact him at http://www.cytoculture.
