I'd vote for burning it. Pour it into a very wide pan like a pizza pan or
make one out of aluminum foil and light it...a wide open pan means you
aren't restricting the flames or fumes, so no explosion or hazard. Then,
you want to keep the can open to let it fully air-out and evaporate.

Makes a lot more sense to pour it on bare ground
even if you have to take it somewhere to find some.

If you'd like,afterward you can fill it with water and dishwashing liquid
to remove the rest of the can's flammability.
