In the world of alternative fuels, Biggreentruck has found two great sources: first, for vegetable oil, we've got an arrangement with the Break 'n' Run bar. They don't do a great volume of oil but we get fuel and they don't have to dispose of used oil.
The second source is a little more unusual (relatively speaking, of course). Turkey Town (http://3-dlaboratory.com/turkeytown.html) is the local supplier for tested and fully legal B100 biodiesel. I'd like to say it's one of the more unusual filling stations I've seen, but....well, vegetable oil comes from some odd places. Considering it's location in a little desert town, this place is downright normal by comparison.
After filling the diesel tanks at Turkey Town, Biggreentruck is currently using ZERO petroleum based fuels!!!!!!!
