<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 />

• Budget: 70 M€<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 />
