Waste management video. There's plenty of YouTube. This sub is highly misinformed in alot of areas. I'm sure there's some small ones that don't sort/pull metals. I know there's ferrous and non ferrous. But shred is between .02-.10 cents max. Don't worry about throwing it away and recycling the 0.00000000000000001% of steel on earth. Even all the other metals like copper, while expensive , hardly rare or in danger of disappearing, your more or less saving some company .10 cents to recycle copper, most of the most comes in the labor and manufacturing, not mining. One of the reasons it's so expensive is we rely so much on recycling and not mining it anymore like we used to when it was cheap, it has nothing to do with it's rarity as an element, which is typical for many of them, gold/silver etc. the prices are artificial and could change by the decade drastically based just on trends, unlike steel.

Most places sort to some degree. Just because you see them dump it into a pile and drive away, doesn't mean it's the end. Not to mention, many cities have seperate trash trucks, one picks up the cans with the robot arm, all the big stuff like fridges, microwaves, washers etc. are picked up by a separate trash truck if the curb guys don't get it and they don't dump that into the dump obviously. 

Metals don't go in the landfill, don't worry
