Of course no one here would put their broken metal clamps in the landfill bin, they would put them in what ever type of recycle bin they have for metal, or drop them in the metal bin at the local depot.

The replace or repair decision is a difficult one, but I think I'll have to retire from my day job before I will ever manage to work my way through my ever growing repair bin, if I don't run out of space for it first. This is of course closely related to the Quality vs Price decision.
