Digging deep for responsible aluminum

Originally published at: Digging deep for responsible aluminum - Fairphone

You probably don’t think about aluminum a lot. We do – it’s one of our 14 focus materials. But we really dug deep when we decided the Fairphone 4 was going to have an aluminum case rather than plastic. And it turns out, aluminum is really interesting.

Start with this: It’s the most common mineral in the Earth’s crust. It’s forged in stars when magnesium picks up an extra electron. So when it comes to supply, there’s a lot of it. But it’s hard to make usable. In 1825, Danish chemist Hans Christian Oersted managed to produce the first malleable aluminum, but it was an outrageously expensive process. For decades, aluminum was as expensive as gold. Napoleon III’s state dinners were proudly served on aluminum plates, and his son waved an aluminum rattle.

In 1886, two inventors simultaneously came up with a process in which aluminum oxide is melted in cryolite (sodium aluminum fluoride) and subjected to an electric current. And to this day, that’s how aluminum is made.

It’s a toy bird, it’s a plane, it’s a soda can

And once it’s made, aluminum’s life span is essentially indefinite. It retains many of its most important properties no matter how many times you remelt and reuse it. And while recycled aluminum isn’t yet of sufficient quality for food-grade and many electronics uses, once it’s made most aluminum can be reused in some way. Some industry estimates claim that 75% of all the aluminum that’s ever been made is still in use thanks to recycling.

But, aluminum isn’t the holy grail of sustainability. It takes a huge amount of energy to get from the stuff in the ground to the stuff that can make a train or a phone. And while it takes only 5% of that energy to recycle the material, the initial carbon and chemical footprint is enormous. And there are lots of ways it gets done wrong, either from an environmental or human rights perspective.

Swipe right for socially and environmentally responsible partners

So when we went looking for the material that would go into the Fairphone 4, we signed up as a downstream supporter of the Aluminium Stewardship Initiative (ASI). ASI’s mission is to recognise and collaboratively foster the responsible production, sourcing and stewardship of aluminium. It is a global standard-setting and certification organisation that lays the foundation for a responsible aluminum supply chain, supported by a broad range of stakeholders.

ASI is laying the foundation for a responsible aluminum supply chain.

ASI has a performance standard made up of 11 sustainability principles and certifies suppliers who meet them. These principles have 59 criteria that address issues including responsible management where worker health and safety are protected, no child labor is used, and biodiversity is safeguarded. We wanted to support workers’ health, rights, and well-being with our supply chain choice, so we set out to find an ASI-certified supplier.

Shining a light on imperfection

We tested both virgin aluminum and post-consumer recycled aluminum and learned about one of the challenges recycled aluminum faces: impurities. To give the phone the highly polished, premium feel that we wanted, we have to anodize the aluminum, which makes the metal shiny. When anodized, those impurities become more visible and make the metal look, well, scratched. Even though it’s not. Try as we might, we couldn’t make recycled aluminum come up to a high enough cosmetic standard that it wouldn’t scare off our sellers and customers.

Proudly framed by ASI-certified aluminum: The Fairphone 4.

After much trial and error, we settled on sourcing virgin aluminum. While we pay a higher price for our aluminum, we’re proud to say our supplier is ASI Performance Standard Certified and they’re as proud to be working with us as we are with them.

Closing the loop

In keeping with our vision for a fair transition to a circular economy, we will continue to explore using post-consumer recycled aluminum in our phones in future. We may have to find a way to make recycled aluminium as ‘clean’ as new aluminum, or come up with a process that makes the imperfections less obvious, but it’s a worthy challenge and one which could have important implications. We look forward to engaging our suppliers and the wider industry on this.

But in the meantime, we’ll continue to make our case: the best way all of us in the electronics industry can reduce the environmental cost of production is to do as we do: ensure that every phone we make is easily recyclable, repairable and that they are made to last as long as is humanly possible.

That seems only fitting for a phone made out of the stuff of stars. Explore it here >>


A very interesting article. I wonder why there are no replys so far. I for myself woudn’t mind imperfections on the aluminum of my phone, knowing the reason why. Why not add an other version of the fairphone to the store, explicitly marketed as “recycled aluminum but with natural imperfections”? It would even be possible to sell it cheaper, according to the article.
Who is with me on this?


Even after 10-15 years, I still miss the “brushed metal” look that Apple’s early iTunes versions had – I really digged it. Maybe imperfect aluminum could resemble that? :thinking:


I would believe the demand for a phone that look scratched will be there if the price is lowered (since we are using recycled aluminum instead of virgin aluminum). These are just variations of a phone and honestly with most phones in a case, you can barely see the phone (other than the screen itself) nowadays.

Hi and welcome to the forum.

So how much cheaper do you think it would be to make a phone with recycled aluminium?

Scrap Al =£1.20p Feb 27 2022
OH let’s say there is less than 100g Al in a phone that’s either side of 15 cents or 12 pence, but it’s probable a lot less.

This is the main cost ~ production

Now consider it may take more resources to get someone to use recycled Al rather than continue manufacturing with the factories default Prime Al

So it may cost more to use it . . .

This Fairphone is not about pricing it’s about fairness.

If Fairphone thought they could use recycled Al without any downside I’m sure the would have even if it cost 100c more.


I see your point. Not saying pricing is all that matters but just saying variability is an option. And the article only mentioned that it’s due to aesthetics that’s why recycled aluminium was not used. Would have been great to illustrate it from a costing perspective if that didn’t make sense as well.
