So if we account for the fact that steel rust and is replaced, titanium is the most environmentally friendly metal?

 

Unfortunately there are difficulties in recycling titanium, complications with contamination and not a large recycling industry.

We tried to get rid of some of our out of date ultracentrifuge rotors, scrap man wouldn't take them, had to analyse them to make any money and they were too small for him to make any money. Returning them to the supplier would work, but oddly fairly heavy so postage expensive, 

I shall keep my ti framed late 90s xc bike forever, and she is still a lot of fun, but replacing componentry is becoming more difficult.

Steel and ali can easily be taken to the local tip.

How does Aluminium compare?

 

Reynolds dont make Alu tubing.... afaik,

My guess is a bit more than SS.  Fundamentally more energy intensive to produce but offset by much more massive economies of scale.  The upside is since 60% of the carbon cost is from the electricity its relatively easy to turn a bigger chunk of it green via renewables.  Downside is that there is so much Alu smelting going on that it will take years to make an appreciable difference.

They pull out stainless steel separately, but what about other grades of "ferrous steel"? I understand some grades go through various different heat treatments, presumably so of which are more energy intensive than others?
