Recycled Content

Recycled content of products manufactured at Port Kembla Steelworks, NSW

At Port Kembla Steelworks, NSW, BlueScope uses the blast furnace-basic oxygen furnace (BF-BOF) steelmaking method to manufacture flat steel products. BlueScope has increased scrap use in the steelmaking process from approx. 21.5% to 25% between FY19 and FY22. This is world leading performance for a BOF and we’re looking to go further.

To request a formal letter on the average recycled content of our products, reported in line with ISO 14021:2016 definitions, please contact BlueScope Steel Direct.

Embodied carbon and scrap steel content

There is a strong relationship between scrap steel content and the embodied carbon of steel products, however, due to scrap dynamics outlined here, scrap steel content is not necessarily a useful metric to assess the sustainability of steel products.

More information on this subject can be found on our Embodied Carbon page. See also this article from ResponsibleSteel™ The ‘Sliding Scale’: Setting Equitable Thresholds to Drive Global Steel Decarbonisation.
