I was interested in that whole ecoli eating plastic and producing 95% acetaminophen from it by mass. Maybe we can stop a lot of the plastic from water/soda bottles and just medicate ourselves till our livers shit themselves out our assholes.

The root problem is that plastic can be recycled but many countries to not motivate their populations to recycle, nor their industries to use reusable containers or to purchase recycled materials and create circular economies. In countries that do have deposit return schemes, reuse & recycling rates are far higher. I see attaching the cap to the bottle as way to squeeze a little more % out of those schemes.
