Various ways to compute this.[1][2] Steel products and scrap are both imported and exported, which confuses things. The data at [3] above seems to treat steel imports as new metal because their recycling inputs are not known.

- dredmorbius 2y agoIt's interesting that the USGS itself (your 2nd reference) seems to disagree with itself (my own ref). I'd need to dig further into figures to see how that emerges. (I'm ... somewhat discounting the AISI data as more likely to be skewed industry-positive, that is, with a higher claimed recycling rate.)
