The antenna isn't, however. In any case, I think there's a pretty high chance these tickets will not end up in a dedicated recycling facility that can properly separate antenna from paper and recycle both, disregarding the chip.

For similar reasons, Japan is phasing out even magnetic stripe single-ride tickets out of recycling concerns (in favor of QR code based ones).

That's not an appropriate comparison, though. Buying a reusable token doesn't take 20 minutes more than buying a paper ticket.

Imagine instead a device manufacturer spending some months of R&D to help every single household in a large country save 4 pennies on their electrical bills, and it doesn't seem so absurd anymore.

No, but it could expend 20x the resources, and not be used 20x as much.

As the article mentions, the purpose of these paper tickets is for single-use or short term use, and the system also supports plastic cards for longer term use.

These tokens are collected at the end of each trip (or you can’t leave). This obviously only works in systems that have mandatory exit turnstiles.
