1. Certification of used materials<br />
– Identify used materials<br />
– Rank <strong>the</strong>m accord<strong>in</strong>g to, for example, toxicity<br />
– Apply colour rank<strong>in</strong>g (red = materials to be avoided, green = materials to be<br />
promoted)<br />
– <strong>CDF</strong> has little knowledge on materials used <strong>in</strong> components<br />

ESA UNCLASSIFIED – For Official Use<br />
– Level stops at ‘unit’ level<br />
– Even elsewhere with<strong>in</strong> ESA, accurate material lists are not well known<br />
– Known only to suppliers to <strong>the</strong> satellite contractor company<br />
– This is <strong>the</strong>ir core bus<strong>in</strong>ess → stays secret<br />
– Exception: propellants<br />
– Processes have an impact on <strong>the</strong> eco-footpr<strong>in</strong>t<br />
– Typically >40% of a satellite is alum<strong>in</strong>ium<br />
– Mach<strong>in</strong>ed out of massive block that has been forged<br />
– Impact of forg<strong>in</strong>g, <strong>the</strong>rmal treatments, etc. should be taken <strong>in</strong>to account<br />
– Is it recycled? Only 5% of <strong>the</strong> energy needed to prdocue metal from bauxite
