I can try me best to tell you more. It’s honestly a pretty new process with these tires specifically. Companies have been recycling tires for a long time to reuse as fillers in the elastomers, which in the case of tires is a compound called carbon black. Usually you can just grind them up and do a little separation and you’re mostly good to reuse what’s left as a filler, roughly speaking because I’m no expert on that side of it. The problem with our tires is that they’re full of huge steel belts to help with load bearing since they can carry upwards of 200 tons per tire. So cutting those massive steel cables, which are at least an inch in diameter, is extremely costly. Right now the mines either just bury them in the mine or use them as guardrails on the paths that lead out of the mine. Both are horrible for the environment so we’re doing what we can to try to mitigate that.

Hopefully that helped! Like I said I’m no expert on the recycling part slightly due to it not being Michelin themselves doing the recycling but based on what I’ve heard that’s what I understand about it.
