as an aside, couldnt biodiesel be made from, say, chicken
grease/hamburger drippings, etc? im sure that all ends up in fry oil,
when you fry fish, nuggets, etc... some fat from the meat ends up in
there as well.

and currently, AFAIK, all that grease/oil/etc is recycled by companies
that turn it into ingredients for everything from dog food to makeup.

so expect prices on that stuff to go up as well, if we start refining it
and burning it in diesel engines on a large scale. in other words, there
is already a demand for that supply of waste oil. its not like it gets
dumped in landfills. or does it?
