The title says it all, I have plans for a Processor that I still need to Build(it is a Drew Orr Design) and I still need to get a source for waste oil but I have a few places that may be available to me.
Due to variables in wvo feedstock and which caustic you plan on using, there is no 'one size fits all' recipe per se. Here is a great website to get you started: make-biodiesel.org
Once you become accustomed to the process, here is a great forum which covers a lot of ground in the biodiesel world with the latest, state of the art methods and procedures discussed: Forums - Powered by Social Strata
Make sure you have a line on your wvo. Now is a good time to build relationships with potential sources, since fuel prices are down. Once the price of fuel climbs again, it will become more difficult to obtain wvo.
