Those workers who operate those machines think nothing of throwing their empty drink cans in the chipper. I have seen some do just that.
Guess they don't realize that the woodchips get used for more than placed around new trees being planted.
You are right on target, they have no clue what all this stuff is going to be used for and more than likely don't care. Now, if the boss were to see that I'll bet they would stop pretty quickly. The "bits" used for these are quite expensive to replace, and yes an aluminum can will work them over.
But, on a side note, in a couple of parks I hunt it I have seen LOTS of old light fixtures and such that were attached to a tree YEARS ago and the tree has "claimed" them for its own. The tree has literally grown around the fixtures and I'll bet most of the wood isn't scanned for metal prior to going in the chipper.
