Titanium seems to top the list in CO2 footprint… ouch!
Where did you get this data? Just curious.
I found it odd that brick features so far down the list. I thought it was an energy intensive beastie due to all the cooking required.
And then having ‘au naturale’ products like granite and slate further up – I wonder what they are taking into account there?
The data was from the PDF I posted in the article previous on bio-resin. Here’s a link to it for you.
Kind of a strange way of looking at it. Most people that own titanium bikes own them for life. Titanium is one of the most durable bike materials. It wont corrode like steel, wont fatigue like aluminium, and wont fail like carbon fibre. By the time you have worn out your ‘normal’ frame material, titanium just goes on and on. Some might say ‘carbon neutral’…
Ti is like Al. They’re like, congealed metallic electricity. V expensive to smelt, refine.
Al fatigues, Ti doesn’t, A decent Ti bike frame made of a Ti alloy like 6/4 will have no problem lasting 50 or a hundred years. with heavy milage Al bikes fatigues & goes quite iffy stiffy in just 5 years or more
