As a kid I remember going past the area around Zug Island on a boat. I have a distinct memory of the huge stacks billowing yellow smoke, and the twists of ductwork forming structures that look like hellish versions of the buildings from a Dr Seuss story [1][2]. It was simultaneously amazing and terrifying, and I couldn't take my eyes off it until it passed out of view. Years later I'd learn about how poorer neighborhoods were in the shadows of and downwind of such places. I don't know if this place is uniquely terrible or this is the invariable cost of steel production. But I imagine this sort of thing is common in the industrializing world today, where a lot of steel is produced. Is there an example of a "better" way to make steel?
