Biodiesel.org maintains a MAP of the U.S. that lists all of the BioDiesel retailers that have listed with them.
Where can I find out more about BioDiesel?
There are a number of excellent links on the web:
Journey to forever ...full of information on biodiesel, as well as how to make your own
Maria "Mark" Alovert's web site on homebrewing ...Mark is very knowledgeable on home brewing of biodiesel
Veggie avenger ...another great site with lots of information
Green car congress...BioDiesel ...a site I found just recently
The Veggie Van ...one of the first and most enthusiastic promoters of BioDiesel
Biodiesel Now ...a GREAT forum for making, using or just talking about BioDiesel!
Fred's TDI Club ...another GREAT forum if you own a VW TDI (diesel) of any model or vintage ...or want to own one; has a section just on biodiesel
Eastern Iowa Biodiesel Enthusiasts ...This is our local YaHoo group of BioDiesel users around Iowa City and Cedar Rapids, Iowa
This includes the Yoderville Bio-D Club; a local processor group for making your own that you can ask to join.
Books on biodiesel:
http://www.itsgood4.us/biodiesel.htm
From the Fryer to the Fuel Tank - by Josh Tickell ...in its 3rd and last print run. This was the first book I read. It got me really enthused about biodiesel.
Biodiesel - by Greg Pahl ...a very new book. I've read this and highly recommend it.
Biodiesel America - by Josh Tickell ...apparently the replacement for "From the Fryer...". I haven't read it yet.
BioDiesel Homebrewers Guide - by Maria "Mark" Alovert ...self published and a little rough around the edges but packed with good info on making it yourself

You need to contact local resturaunt owners and get deals with them to take it off their hands. There was a segment on the show "Dirty Jobs" on just that.
