Got some really old 14 ounce handheld propane torch cylinders in the

While it would be fun to take them out in the woods and lock and load on
them from a safe distance, that's probably not the recommended disposal
method. I was thinking of just opening the burner valve on the partially
used one in the back yard and letting all the propane escape, then
screwing the burner in to each of the others and do the same.

Better ideas?

This is what one manufacturer says:

It says contact your local solid waste disposal facility.
