I used to live in an area with a similar system for rubbish (near Wembley Stadium, in north west London). While it worked, it suffered from a number of “quality of life” issues. The chute terminals had quite a small aperture, with a sealed door; presumably to make it easier to create the necessary pressure differential. This happened regularly; every 30 minutes (or so) during daylight hours. It was loud. Really loud! With several terminals in a courtyard, running in a sequence, it was almost a never ending reverberation. Of course, you can’t use them while they’re in this cycle. If anyone overfilled them — which was very easy — or ended up jamming the door open with some misshapen detritus then, try as it might, it just wouldn’t work at all. The building management were regularly seen wielding a broom, to try to force stuck loads down. Then, if you had anything that just couldn’t be made small enough for the chute, you had to use the (limited) dumpsters anyway; many did, because it was often just easier. That’s not to say I think it wasn’t a good idea. It just needed its rough edges smoothed out a bit.
