What's the name of the place where you can get money for every kilo of iron, copper or aluminum you bring in? Collecting yard?
I know that here in California, USA, they're called recycling centers. I assume this usage extends to the rest of the US.
Californians don't have to go out of their way to recycle. There are 1,687 recycling centers statewide that buy back empty California Refund Value (CRV) beverage containers, most conveniently located near places you live and work.
I think they're also called recycling centres in the UK.
There are recycling centres and scrap dealers all across the UK that will pay for a bundle of aluminium cans. (thinkcans.net)
I think another name for it might be scrapyard, but I'm not entirely sure. I think this might be used more with cars or other bulky items. Here's one usage I found online
