Are tin cans actually useful for something?

[Freddy]

I have a lot of tins cans from soup and hering in my apartment and I wonder if thy are actually useful for anything, like scrap, selling, or something like that.

They can be smelted into steel bars.

Huh, interesting. So I'm not going to throw them away then. Thank you.
