From mid-November to mid January, Bainbridge Island Ace Hardware accepts old lightstrings. They are then picked up by a Kingston metal recycler.
If you want to recycle lightstrings outside of the above time frame, you may pay the shipping costs to send them to Sussex, Wisconsin, where a company will make sure they are recycled. Follow the instructions on this website.
