The article is not about UI. A chunk of the article is aimed at correcting the idea that UX is UI.

The author does provide a UX solution, which is to cut the number of bins to two or one.

But going to one bin makes recycling impossible. So really, that just ignores the problem or decides it's too hard to solve. What I'd love to see is a solution that makes disposing of trash easy while also allowing for recycling.

FWIW, recycling is not "impossible" if the trash is not pre-sorted by the people throwing it away, it's just harder for the people who have to do the final sort (presumably someone is there at the end correcting the mistakes of all the non-expert trash bin users out there).

Why would one-bin be impossible? We have ways to differentiate commingled glass, plastic, and metal automatically (and mechanically). We can get fancier with AI if we need to.

Always use the word impossible with the greatest care. Everything is always impossible right up to the moment it is done.

And most things are never done.
