So, thanks to Apple AirTags, we’ve discovered the plastic trash slated for recycling is just piling up while the processing facility is waiting for its machinery to arrive.
This seems like a non-issue. The plastic is still scheduled to be repurposed. It's not like storing it for some time while a facility is being built will likely affect where it will eventually end up. Who cares if it is piling up? It sounds like the facility will need a steady supply of material on-hand when it opens to ensure continuous operation, so that seems like a perfectly sensible solution. It's possible that the facility might not be as environmentally-friendly as some other options, but the fact that the material is being temporarily stockpiled instead of getting fully processed right away should not matter.
The real story should be about the wasteful person who considered it a reasonable idea to throw away a perfectly functional tracking device just so they could virtue-signal online, while polluting a batch of recyclable plastic with a lithium battery and other components. And of course, the click-bait journalists who likewise regurgitate non-stories like this and skew the perspective for ad revenue without care of whether or not the story has any real merit.
I remember seeing them as a kid. "It's the three R's!"
The biggest part of "The Three Rs" should be the first two, reducing and reusing, so that there is less to recycle or otherwise dispose of. Too often people buy lots of things that they really don't need, and throw them away when they are still perfectly functional or repairable. A person who considers a working tracking device to be disposable might be the kind of person who is the center of the problem, frequently replacing and tossing out electronics and other things as soon as something new arrives.
And they may have had good intentions and just wanted to verify that the plastic wasn't being sent directly to a landfill, but even then it would be hard to tell if the tracking device wasn't simply sorted out due to it obviously not being recyclable, at least without more advanced processing.
