Can probably find a metal recycling place that will take it. I kinda doubt they'd buy it from you but at least it's more productive than putting it in a landfill.
Also there are rim repair places that might be able to fix it up. I wrecked a car once and bent up three of the rims to some extent. Took it to a good local alloy wheel repair shop and they made them usable again so I could sell them.
Maybe a scrap yard will give you a little bit of money for it, and it's a waste of money trying to get your rim repaired unless you really want a whole set of stock wheels for winter tires or something. But once you get a quote for how much it's going to cost you, you'll realize it's not cost effective at all to have it repaired rather than to purchase one from someone on here. If everything else fails, listen to GoFast...
