An example for this is our Sanmac® 316L. Thanks to its exceptionally high recycled content, Sanmac® 316L demonstrates a remarkably lower carbon footprint compared to conventional stainless steel production. Based on current LCA results, Sanmac® 316L is estimated to have a carbon footprint that is 71% lower than the global average for stainless steel*.

Sourcing

Energy

Alleima’s location in Sweden has helped the company to keep its carbon emissions low in comparison to other parts of the world. In Sweden, close to 100% of the electricity is fossil-free, while it for instance is 72% and 42% in China.

Raw materials

Producing stainless steel requires raw materials and energy, with sourcing and production methods impacting carbon footprint. The carbon footprint varies significantly based on the sourcing location of the raw materials and by maximizing the use of recycled material, the carbon footprint is significantly reduced. When producing Sanmac® 316L, Alleima used an average of 94% recycled materials in 2024. The remaining 6% accounts for 62% of the product carbon footprint. In Europe, the average amount of recycled materials is 85%, while in Asia it is about 31%. This requires the use of more virgin alloys, leading to significantly higher carbon emissions.

"The fastest way to reduce your scope 3 emissions is to buy material from Alleima"

Marcus Hillbom, Business development manager Alleima

Alleima is committed to producing industry-leading materials that excel in quality, performance and carbon footprint. With our third-party reviewed LCAs, customers can easily compare our products against alternative materials and make informed choices. By choosing material with lower carbon footprints, customers can significantly reduce the overall climate impact of their final products and accelerate progress toward their climate reduction targets

Significant Carbon Footprint Reduction for Sanmac® 2205 Achieved Through Updated 2024 LCA Model

When the LCA model for solid bars was updated with production data for 2024, results showed clear improvements in the carbon footprint with reduction of up to 26% was achieved for Sanmac® 2205. This underscores the value of regularly updating the LCA model with current data to accurately reflect on-going sustainability efforts. Some examples of what is driving this continued improvement are more accurate calculations of the steelmaking emissions, increased use of biogas and the integration of more supplier-specific data.

Q&A

The carbon footprint is available on the certificate. The ISO standard followed is mentioned, and there is a 2.2 section at the bottom of the certificate where you can find the data.

If there is no data in the MTC, there is no data available.

For access to the LCA reports, please contact your Alleima sales representative.

To provide reliable and solid LCA data, the Alleima LCA model has been reviewed by IVL – Swedish Environmental Research Institute (IVL), which has long experience and a high level of competence within this field. IVL has also supported in the development of the data management and the development of the model as such.
