Recycled Content

Recycled steel scrap

Recycled content of products manufactured by BlueScope in Australia

At Port Kembla Steelworks, NSW, BlueScope uses the blast furnace-basic oxygen furnace (BF-BOF) steelmaking method to manufacture flat steel products.

Across the range of steel products manufactured at Port Kembla Steelworks, the average recycled content in the steel is approximately 24%, which includes both pre-consumer1 and post-consumer2 recycled materials. The figures provided are based on FY26 data.

In addition, 2% of the steel is produced using internal scrap recovered and returned to the steelmaking process.3

Together, this means that approximately 26% of the material used in steelmaking comes from scrap sources.

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

Despite being one of the most recycled materials in the world, there is not enough steel scrap available to meet the growing global demand for steel.4

Scrap steel is known as ‘resource-constrained material’ i.e.

  • supply volume is limited
  • supply is less than the current demand
  • supply does not readily increase in response to further increases in demand.

If larger amounts of a constrained material, such as scrap steel, are used on one project, there is less of that material available for other projects. This means that using steel products with higher levels of recycled content on specific projects does not result in a net reduction in global emissions – merely a shift in who claims the benefit..

“Steel with a high recycled scrap content (such as that generated by most electric arc furnaces) should be used by the construction industry where appropriate, but it should not be specified purely in the hope of reducing global greenhouse gas emissions. This also means that where project-level carbon limits or targets are met through specifying high percentages of recycled steel, this won’t lead to global GHG emission reductions.”5

Recommendations for designers, specifiers and purchasers

To support decarbonisation of the steel sector and to avoid ‘emissions shuffling’, associated with globally constrained materials such as scrap steel, read the recommendations outlined in Embodied Carbon and Steel Products.

Footnotes:

  1. Material diverted from the waste stream during a manufacturing process and used as an input to a new product. This may originate from BlueScope or external sources. At BlueScope, this includes scrap generated during downstream processes such as rolling, coating, painting, rollforming, fabrication and cutting that is recovered and returned to steelmaking, but excludes scrap that is generated and reused within the same steelmaking process that created it.
  2. Material recovered from products that have completed their intended use and would otherwise be disposed of as waste. Examples include steel recovered from end-of-life vehicles, household appliances, buildings, infrastructure, machinery and packaging, which is processed and recycled into new steel products.
  3. Recycled and recovered content classifications follow ISO 14021:2016. The approximately 2% recovered content refers to internal scrap and iron-bearing materials generated and reused within BlueScope’s steelmaking operations up to and including slab casting. Consistent with ISO 14021, this material is reported separately from recycled content. It excludes scrap generated during downstream processes after slab casting, such as rolling, coating, painting, rollforming, fabrication, cutting and other finishing operations. The figures provided are based on FY26 data.
