That's steel recycling, not production of new steel.
- throwaway5959 3y agoOn a long enough time horizon wouldn’t it make sense for most steel to be recycled? I think we already get a lot of our aluminum from recycling.
- _hypx 3y agoMaybe. A lot of grades of steel cannot be made from scrap metal. At some point, you have to be able to turn iron rust in new steel, even if that rust comes from old steel.
- credit_guy 3y agoBut most steel is already being recycled, at least in the US, according to the US Geological Surveys [1] > Recycling rates, which fluctuate annually, were estimated to be 98% for structural steel from construction, 88% for appliances, 71% for rebar and reinforcement steel, and 70% for steel packaging. The recycling rates for appliance, can, and construction steel are expected to increase in the United States and in emerging industrial countries at an even greater rate. Public interest in recycling continues, and recycling is becoming more profitable and convenient as environmental regulations for primary production increase.

- _hypx 3y agoThat's not true globally. Only 40% of global steel supply is from recycled steel. https://www.theworldcounts.com/challenges/planet-earth/mining/advantages-of-recycling-steel https://www.theworldcounts.com/challenges/planet-earth/minin...
- credit_guy 3y agoThe following 2 statements can (and are) true simultaneously: 1. most steel is recycled 2. most produced steel comes from iron ore, and not from scrap steel.
