Circularity of steel whilst reinventing itself in automotive

EUROFER, THE EUROPEAN STEEL ASSOCIATION

• EUROFER (° 1976)
• It represents 100 per cent of steel production in the European Union
• EUROFER members are steel companies and national steel federations

throughout the EU

• The European steel industry has a turnover of about 170 billion euros and

direct employment of about 330 thousand highly skilled people, producing

• n average 170 million tonnes of steel per year
• More than 500 steel production sites in 24 EU Member States provide direct

and indirect employment and a living for millions of European citizens.

• Closely integrated with the European manufacturing industries, steel

producers provide the basic material for innovation, growth and wealth in

• Europe. Thousands of different types of steel facilitate and improve our daily

life

• Steel is 100 per cent recyclable and therefore contributes significantly to the

conservation of fundamental resources. As a basic engineering material, steel is also essential in innovative technologies for more resource efficiency and sustainable development in Europe.

MAIN CHALLENGES FOR THE AUTOMOTIVE INDUSTRY TODAY

› SUSTAINABILITY › Fuel economy and emission reduction regulations › Electrification › Autonomous driving › Car sharing › ENHANCED SAFETY PERFORMANCE › AFFORDABILITY › GLOBAL PLATFORMS › GEOGRAPHICAL PRODUCTION SHIFTS

“REINVENTING STEEL” IN AUTOMOTIVE

• Advanced steel solutions replacing “traditional” steels:

– reducing weight and improving crash resistance; – combining strength with ductility: hot stamping, tailor welded blanks, …

Example of application of press hardened steels: Volvo XC 90

40% of the Volvo XC90 uses press hardened steel – the most in any vehicle

125 kg lighter than its predecessor and 200 kg lighter than most of its competitors .

“TRUE RECYCLING”, WITH STEEL A “PERMANENT MATERIAL”

• End-of-life vehicle:

– dismantling & parts salvaging → parts for reuse or remanufacturing – depollution & shredding → material for recycling

• Magnetic properties of steel: superior collection and pre-sorting in clean

fraction.

• Final recycling process: chemical cleaning of scrap and new steel products with

“intact” properties (no downcycling !)

• A “permanent material” (BSI) standard 8905:2011, the above recycling loop can

be continuously perpetuated;

• In EU, more >50% of all steel produced is made from ferrous scrap.

LIFE-CYCLE PERSPECTIVE IN ENVIRONMENTAL ASSESSMENT AND REGULATION

Towards addressing embedded emissions:  Information sharing platform  Voluntary LCA reporting  EU-wide product category rules  Life cycle based credit

CONCLUSIONS

1. Steel “reinvented” in automotive: advanced solutions enable major weight saving while improving crash resistance; 2. Superior recycling performance : “true” recycling, as steel is “a permanent material”; 3. Life-cycle perspective supporting environmental assessment and regulation.
