Instead of throwing them away, you could always donate them to Goodwill or the Salvation Army or something. Yeah, it still leaves the 'not healthy' cookware in the field, but sometimes that stuff may be the best someone can hope for. I know, I've been there and when it comes down to having *any* pot to cook with compared to *no* pot, well, as the saying goes, beggars can't be choosers.
Remember, you didn't manufacture those pots and pans. At least donating, you won't feel like you're getting blood money for them. Small comfort, but humans justify and rationalize much worse things ....
I know some of more righteous substance would shout "throw away!" and, if I hadn't been in dire need before, I might agree with them. All in perspective and motive. Throwing them into a landfill may just mean that yet another set is bought new, further feeding the manufacturers.
Bless them well, whatever you do, and don't worry about them. We all have our own paths, you can't control what someone else does on theirs. For all you know, after you donate them, they may sit abandoned in a corner for a decade and eventually end up being thrown away anyhow.
