• The structural steel making process boasts a 95% water recycling rate with no external discharges, resulting in a net consumption of only 70 gallons per ton.
• Steel is the most recycled material in the world.  Domestic mills recycle more than 70 million tons of scrap each year and structural steel has a 93% recycled content!
• Steel production productivity levels are up by a factor of 24 and labor hours have been reduced from 12 to just 0.5 tons per ton.
• Steel’s carbon footprint is down 37%, energy use has decreased 32%, and greenhouse gas emissions have dropped by 45%.
