Yes, cellulose is a polymer of simple sugars. However most organisms lack the enzymes to break the chain up into its individual units. Ruminants and termites have symbiotic bacteria that digest it for them, and some species of fungus can break down cellulose (think mushrooms on a fallen tree) but as it stands, using cellulosic feedstocks require breaking up the chain via enzymes (expensive) or acids (nasty) so that bacteria can utilize it.
And yes, newspaper does burn quite well, but I'd like to see you stuff it in your gas tank.
