Biofuels don't have to be made from crops. We have an enormous waste
stream with high carbon content. Imagine a process to convert that into
methane and oil, which could then be reused to produce virgin plastic.
Or fuel jet planes.
I've seen a prototype reactor (high pressure, high temp, with a
catalyst) that does that with wood fibers with no water residue and
virtually no mineral contamination. It theoretically would also work for
paper and plastic waste, though I'm not sure that has been tested.

Perhaps some day this will be true. However, the major 'biofuel' we produce in
the USA is ethanol and numerous studies indicates that the way we produce
ethanol uses more pertroleum fuel that it offsets.
Worse than that, the polution that results from farming and refining ethanol
(mostly)stays in this country while the majority of the ethanol is sold to
overseas customers.
Then there is the fact that growing biofuel uses a lot of land (as well as
other resources), if we used ALL of the arable land in the USA to grow biofuel,
it wouldn't offset even 1/4 of our petroleum consumption. And of course if we
use all of the land to grow fuel, we wouldn't have any food to eat.
If we could figure out how to grow fuel without consuming massive amount of
petroleum, then it might make sense to grow limited amount of biofuel for those
applications that can't be solved with electricity. However, I suspect that
long before we solve that problem, there will no longer be applications that
can't be solved with electricity, or some other green solution they might come
up with.
