Brian asks "I guess the question remains for denatured alcohol, however; I've been in that situation too,"
SLX evaporates leaving no residue. It contains no ozone depleting chemicals. Deep breath here because I'm awaiting the controversy... pour it on a flat rock and allow it to evaporate. Wrap the used container in newspaper and dispose of it in a normal trash container.
I try to be as green as I can. Sometimes, we have to exercise our best options and move on. Ethanol would be a great fuel if not for the price and availabilty issues. If you can get Everclear, and it works for you, that's pretty close to THE "green" liquid fuel for backpacking.
YMMV and probably does.
edited to clarify
Changed THE "green" fuel to THE "green" liquid fuel, because most of us don't cook over wood.
