You raise several very important points simultaneously.
Forgive me, but I can't answer your question in French given the technical component.
I would say two things. The first is that the example you gave of mixed recycling is actually the best example of why we need to consider advanced recycling and chemical recycling, because those advanced and chemical recycling mechanisms are able to best break down those polymers into something that can be easily reused.
What we do there is create a building block, and when you are able to distill these very complex mixtures of molecules back down into the original ethylene, or whatever the other polymers and monomers may be, you can then redeploy them.
How do we do that simply and easily? That's a multi-million dollar question that we're working on and we continue to work on. We still believe that the primary driver for that is improvements in the materials ecosystem that I referred to in my presentation.
There are many different areas where we can make investments to improve the recapture of these products, because—let's be honest—this is valuable material that we are just throwing away. We should be able to reposition and reinvest into these materials, and that would preclude the need for us to have virgin resources coming out of the ground.
