It's not "new" steel..... the stuff that's being turned out there is like everywhere else in the country.....it's "recycled" steel. I have family working steel from that area..... it's all remelted scrap. Both "automotive" and "structural" are just euphemistically renamed scrap steel. When I use the term "new"..... that means from scratch.
The way Aldo got started was when all the steel plants across the midwest/northeast shut down.....he was buying the ingots of carbon/alloy steel for pennies on the dollar, and when it ran out, he had no choice other then to have it made in Germany....because all the plants that make/made new/or those types of steel had gone under.
It's true that almost all "new" steel has some amount of scrap in it, especially in the mini mills and EAFs, as you have to "prime" the arc furnaces, and it's much more cost effective to use scrap. That said, the larger mills like ArcelorMittal (formerly Bethlehem Steel) and US Steel still use raw ore and virgin metals for casting slabs.
At any rate, steel can be recycled very efficiently without compromising the end product, and the chemistry of the steel is still very strictly controlled and tested. Any scrap that is used will make up a relatively small percentage of the final product anyway (say 10% or so) in most cases, but from a cost/efficiency standpoint, it doesn't make sense NOT to use scrap.
As far as I know, this is how ALL steel is made, even in the European mills. Now, you do obviously have different kinds of scrap (what is known as "single origin scrap" for instance), and different methods of grading and sorting, how much goes in. etc... and not all steel is created equal by any means, but this is less a function of how much scrap was used, and more of what kind and how well the overall process was controlled, from heat, to casting, to rolling, etc...
Mini-mills (like where much of the cutlery grade steel is going to come) control this a little better. Smaller heats, better process control, higher grading standards, etc...
