I've been burning TP for years. When I make the trip into the woods I pick up hollow tubes of birch bark as both caddy and accelerant, further scraps of birch bark ensure complete combustion.

I burn mine, but I do it a little different than most.
Obviously this can't be done in dry/fire conditions, but then you shouldn't have a campfire then either.

I dig my cat hole, do my business THEN take my Bic and light the paper in the cat hole. Wait a few seconds to insure complete burn and no hot ashes in air, then cover with dirt/duff and mark spot with stick.

Works fine for me, but might be an issue for others.
