Even putting aside the heavy metals, the assumption that they burn into CO2 is a hard one to accomplish in fact. Done improperly, you end up with a very snokey, sooty smoke. Done properly, you’re dealing with very high T, which is hard, and NOx production. But, assuming you’re doing a good job... burn baby burn! (Just separate out the per-fluorinates - HF is nasty)
