Yes, but now the soda bottles in that patch will have their caps attached. So that's sort of, well, I suppose ... you may have a point.
More seriously I'm fully convinced that this cap attachment nonsense is purely to save coca cola et. al. further costs in recycling bottles. Like it's still a small step forward, but it wouldn't happen if corpos weren't saving a dime.
PET is recycled as in: every supermarket has an drop off point, giving you back 25cnt for every large bottle, 15cnt for small and cans.
Plastic in the general garbage is separated (not 100%, but still) and either separated (polystyrene is easy to detect and seperate for instance) or sold to companies that repurpose them (more and more of those white triangle things in the corners of roads are repurposed strengthened plastics now).
I'm sure plenty will find its way to either landfill (that we don't have much) or gets burnt. But it's not as bad as the US, which was my point in the first place.
