Outokumpu, the global leader in stainless steel, is partnering with Thyssenkrupp Materials Processing Europe, a leading steel and aluminium service centre, and Boysen Group, a premium exhaust system manufacturer, to introduce the world’s first towards-zero stainless steel to the automotive industry. Outokumpu’s Circle Green is the world’s most sustainable stainless steel with up to 92pct lower carbon footprint than the industry average. The companies aim to supply larger quantities of Outokumpu’s Circle Green product to the industry as of the second half of 2023.
Tailpipe emissions from cars, trucks, and other road vehicles account for around 75pct of all carbon emissions from mobility, approximately six gigatons of CO2 per year. The shift to low-emission vehicles will disrupt the entire automotive supply chain and create a significant change in the market for auto components.
As part of the collaboration, Outokumpu supplies the material to Thyssenkrupp Materials Processing Europe, the service centre experts then take care of processing the master coil into slit strips and manages the just-in-time delivery to the Boysen Group.
The supply of CO2 reduced material is an important building block in the sustainability strategy of Thyssenkrupp Materials Services, the parent company of Thyssenkrupp Materials Processing Europe.
With the procurement and use of decarbonized stainless steel, the Boysen Group is acting as a role model in the automotive industry towards more sustainable supply chains. The use of Circle Green enables the Boysen Group an enormous savings potential in CO2 emissions and thereby actively contributes to climate protection – at the same time supporting the company target of protecting, preserving, and shaping the environment.
Outokumpu’s Circle Green has set a global precedent, as no other stainless steel manufacturer has achieved such low emission levels throughout the entire production chain from raw material extraction to final production.
