<strong>Steel</strong> – Truly Recyclable<br />
Once steel is made it enters <strong>the</strong> world stock of steel. It may stay <strong>the</strong>re <strong>for</strong> 1<br />
month or 100 years, but it will eventually join <strong>the</strong> true recycling loop
Sustainability of steel<br />
<strong>Steel</strong> industry strives <strong>for</strong> continuous improvement of <strong>the</strong>ir environmental<br />
per<strong>for</strong>mance and sustainability<br />
• <strong>Steel</strong> is 100 % recyclable<br />
• New steel qualities improve sustainability of our<br />
consumers products<br />
• <strong>Steel</strong> industry is committed to ongoing energy saving and<br />
reduction of CO 2 emission<br />
• <strong>Steel</strong> accounts <strong>for</strong> 5 % of man-made CO 2
The ULCOS project<br />
Objective:<br />
50% reduction in CO 2<br />
emissions per ton of steel from iron ore b<strong>as</strong>ed steel<br />
production by 2050<br />
• Globally <strong>the</strong> largest <strong>Steel</strong> Industry project on Climate Change<br />
• Core partners: ArcelorMittal, Tata <strong>Steel</strong>, ThyssenKrupp, Ilva, Voestalpine, LKAB,<br />
Dillingen/Saarstahl, SSAB, Rautaruukki<br />
• Co-partners: over 40 Institutes, Universities, Engineering companies, etc<br />

An example of smart <strong>material</strong> use
Facts and goals of <strong>the</strong> study<br />
• Facts<br />
• FSV is <strong>the</strong> successor of <strong>the</strong> recognized lightweight<br />
studies<br />
ULSAB 1998 and ULSAB-AVC 2001<br />
• Electrical vehicles are currently more demanding<br />
regarding weight saving so <strong>the</strong>y are more<br />
challenging to prove that steel is <strong>the</strong> best choice<br />
• Goals<br />
• Development of a smart lightweight steel BIW <strong>for</strong> an<br />
electrical vehicle (and 3 derivates) projected in 2020<br />
at large volume (100.000 p.a.)<br />
• Demonstration of latest steel grades and steel part<br />
manufacturing technologies<br />
• Development of <strong>sustainable</strong> and cost-effective<br />
solutions<br />
