This article makes it sound like the main bottleneck in the first-run recycling process is sorting. Could anyone with knowledge around ML, robotics and the like chime in on napkin math around novel labor-reducing approaches to improving the operating economics here? From the sound of it, this is not really a solvable problem short of some leapfrog technological advance. Even then, you don’t want to spend more energy…
I haven't seen the output so I can't comment on how well they work firsthand, but the idea is pretty cool. As far as I know (which is not far) they don't attempt to sort recyclables by material, unfortunately.
