google biodiesel for all kinds of reading. I was finally getting ready to put together a waste vegetable oil (WVO) processor and then I find out things are getting really goofy on sources of WVO. In the not-too-distant past, restaurants were happy to have someone haul off the WVO free of charge, since they typically had to pay to have it removed. Then the value began to climb and it went from free to pretty pricey. The new oil suppliers have gotten into the game now, too, by offering credits against the purchase of new oil with the return of the old oil.
So, here I sit once again - a day late and a dollar short.
