Saying biodiesel is biodegradeable and decomposes quickly is marketing nonsense - it's just a bit LESS toxic than regular diesel - methanol and lye - the methoxide mix that causes the transesterification reaction in vegetable oil is certainly toxic, and quite flammable. Gotta be careful with that stuff.
Barbwire - depends on the scale of setup you're looking for. There are plenty of plans if you search google to build small scale processors. Some who want less hassle will go this route ; www.biodieselgear.com . They have some SWEET stuff there, and isn't too bad of a price if you go in on it with a buddy or two. IF a tdr member in Cleveland had space for one of these things, I'd be all over chipping in!!
