Pierre, welcome.
Let's talk about circularity.
What role does it have to play in the climate conversation?
So, circularity is certainly a very large role because one
thing we've come to all realize during COP is that energy is
going to be the limiting factor for decarbonization.
And in the case of aluminum, circularity means saving 95% of
the energy and the greenhouse gases that you would emit with
primary aluminum.
So it's a massive benefit for decarbonization.
How do we scale?
What are the challenges that you face?
So today, scaling is limited by three things.
The first one is innovation.
In order to improve circularity, we need to be able to sort and
segregate the different scrap alloys to avoid downcycling.
And while there are promising technologies, they're not fully
scaled up yet.
The second one is scrap availability.
We need to make sure that scrap is not disappearing and that we
can increase the size of the pie.
And the third one is policy, which has to do a little bit
with the previous point, but we need governments to help us make
sure that, for instance, used beverage cans are not going to
be landfilled, but properly collected and recycled.
You mentioned innovations at the top there. Which have the most
potential, do you think, to really unlock this industry?
So, we're working with a number of different technology
providers,
specifically around sorting and segregation.
We have seen laser-induced base spectroscopy, or LIPS, being
very promising for sorting.
We've also seen AI being very useful, combined with cameras,
to be able to learn from the different types of scrap that
the cameras see, and decide which one is going to be good
for recycling, and which one is not.
And so I think you know, AI is going to certainly bring a lot
of good things for scalability.
Yeah.
Thank you so much.
