The recent European switch to attached bottle lids for recycling is very interesting to me, because as an American I've always been told that plastic bottle caps *cannot* be recycled, and should be thrown in the trash while only the bottle itself gets recycled.

Anybody know the origin for this? Was it just a desire to sell more single-use plastics? Are detached lids so small that the effort to extract them from the waste stream is too much to justify the amount of material you get? Something else?

@azonenberg it's attached so they don't end up in the water was my understanding, not to do with recycling per-se, just that you don't want them coming off and going into stormwater.

@dotstdy ah, interesting.

So there is still ~no recycling for bottle caps? Attaching them seemed weird to me because they're typically a different type of plastic than the bottle itself, so you'd need to separate them before you could recycle either.

@azonenberg not really sure, as far as i understand it plastic recycling in general is uh... not really recycling in general. so my expectation would be that it makes no real difference.
@dotstdy Yeah I know, that's why I was confused. Like, it seemed silly to go through all this engineering effort to hold onto a tiny bit of what's essentially garbage and isn't going to be usefully recycleable anyway.
