BMW Group Turns to thyssenkrupp for bluemint® Steel
02/23/2026 - thyssenkrupp announced it has been selected to supply bluemint® recycled CO2-reduced steel to the BMW Group beginning in 2026 for use in the outer panels, interior parts and battery housing of the BMW iX3.
The company said bluemint steel is a mass-balanced recycled product with its CO2 savings verified by TÜV Süd. The existing processes will not need to be adapted to use it in series production.
While most steel used in outer panel components for automotives is primary steel due to the high requirements for surface quality, formability and processing, bluemint recycled has been proven to meet those requirements. Produced with a blast furnace, it reduces the use of coking coal and cuts CO2 emissions, the company said.
“The fact that bluemint® Steel is used for both outer panel components and battery housings shows the great potential of CO₂-reduced steel. Electromobility and climate friendly steel together make an important contribution to reducing industrial emissions,” said Georgios Giovanakis, chief sales officer at thyssenkrupp Steel.
The CO2-reduced steel has better electromagnetic shielding than other materials, stabilizing the system’s performance and reducing the design effort required for more measures. The company said the use of scrap in bluemint also allows for more of the vehicles to be recycled in the future.
