    Environmental Sustainability

    Our steel leads many lives.

    Instead of blast furnaces, our mini mills are driven by electric arc furnaces, which use scrap as their main raw material. As a result, our mills recycle 1,200 lbs. of steel every second, making Nucor the single largest recycler in North America. No other manufacturer makes steel more sustainably.

    In fact, our EAFs save 1,705 kilowatt hours of electricity per ton.

    They also release 86 fewer lbs. of air pollutants per ton—or more than 2 million tons less pollution per year than blast furnaces.

    Thinking about meeting C.A.F.E. Standards with aluminum or carbon fiber?

    Consider this - carbon fiber can be recycled, it's just difficult and it can't be used for the same end use after recycling.

    when you compare manufacturing processes,

    steel is much greener than aluminum or carbon fiber

    — not to mention the car buyer’s perception that steel is safer. Bottom line, our steel not only leads many lives, it’s making our lives better.
