Wasn't talking about enzymes... If you heat cellulose enough in the absence of
oxygen (sawdust, paper, cotton, corn stalks/husks) then you end up with
charcoal, methanol and gunk. the methanol can be used as fuel and the rest can
be used to heat the still. Of course I did this 30 years ago at a time in my
life when I didn't use my brain for thinking, so I might be a bit hazy on the
economies of the reaction.

30 years ago you might have gotten away
with using "gunk" as a fuel as well.
Unless you live a long way from neighbors
you probably can't do it now.
