is approximately 1/3 the global average of extractive,
blast furnace steelmakers for Scopes 1, 2 and 3.
We’re proud to be a part of a circular economy, minimizing waste and energy use and reusing all materials so that almost nothing is discarded. The steel in a Model T may have been recycled into rebar, which was recycled into a train, which eventually became a windmill. The cycle lives on.
Steel can be infinitely recycled and reused without any quality loss. Nucor steel products are made from an average of 77.0% recycled content, with some products containing almost 100% recycled content. We also recycle more than 90% of the dust from our electric arc furnaces (EAF).
*2022 data
For more than 50 years Nucor has pioneered circular, electric arc furnace (EAF) steelmaking that recycles scrap into new steel.
Nucor’s circular steel mill GHG intensity is approximately 1/3 the global average of extractive, blast furnace steelmakers for Scopes 1, 2 and 3.*
