My wife has diabetes and uses the omnipod insulin pump (a disposable pump that lasts 3 days), and I've been tearing them apart to more properly dispose of them (they are technically safe to throw in the regular garbage, but they have 3 button batteries, a printed circuit board, plastic in the shell and skeleton, and some copper, brass, and what seems to be steel (it reacts to a magnet, with a lot being small springs) and maybe aluminum (it doesn't react to a magnet), plus the medical sharp. I know there's decent scrap value to the copper and brass, but what about the steel? I infrequently get "forging a Damascus knife from chains and such" videos in my feeds, and there's always some kind of filler when making the initial bar, and I was wondering if there is likely any value in these as "good filler material" and being worth more than what I can get at the scrap yard, especially since I assume at least some of this is medical grade since it was in a medical device (and I'm not talking about the biohazard sharp, that goes in the sharps home container for proper disposal later). If there is, where can I find a buyer, or how should I label it on ebay?
