You'd probably be best off burning them by "recycling" some sort of timed firebomb. Ideally this would be done with something that has some plausible deniability (have somebody "recycle" some crumbled newspaper before you, then "recycle" a (modified?) cigarette butt). Of course firebombing the cans is probably very more illegal than just dumping a can of lighter fluid into it and throwing in a match... I mean, even that is arson, nothing to sneeze at. You would have to balance the possibility of being caught with the punishment if you are caught.
