I wasn't able to find anything about using the stuff that come out of the chimney. I was wondering if there was anything useful that can be done with it?
I'd probably add it to my compost or save it for throwing on icy walks and driveways.

If you're talking about chimney soot (creosote), I would just burn it in very small amounts in a smallish fire in a wood stove. It burns hot and intensely; burning large emounts can generate enough heat to damage a stove or stovepipe.
For other uses, I did a focused search (duckduckgo) and the first two links that came up were from Permies!
Personally, I wouldn't put it in compost or food growing areas. I can't find much on wood creosote specifically, but creosotes in general don't appear to be particularly healthy. Ash/char is a different story, as long as you're mindful of the pH of your soil.
I think of wood creosote as energy to be utilized, carefully. For my money that's the best method of disposal.
Doug is right. Not the compost. I'll still stand by my de-icing use, though.
