Dryer lint makes an okay fire starter for a smoker, I know people who keep a coffee can or such near the dryer for collecting it, but I wouldn't use it for smoker fuel, too much synthetics.
Near use wax, especiall petrolium derived wax, in your smoker. It not only makes for rancid smoke but coats the inside of the smoker like creosote in a chimney. The smoke makes the bees mad (as noted earlier) and those occassional explosions can be hazardous to both bees and keeper.
Having livestock I use burlap feed sacks or bailing twine for smoker fuel, sometimes both. Make sure the bailing twine is not synthetic.
What I do use take a small bit of newsprint, roll it like a straw, lay it beside a small chunk of old crumbling wood or savings, then wrap that with either burlap or twine. Newsprint is for a fast start, Wood chips are to act as coals to hold the heat, and the burlap or twine creates the smoke. If the smoke gets to hot, add some green grass or leaves to cool it down.
