Two ways a recycling yard wastes your Saturday, and only one of them is the queue
Hi, we're SONAH in Aachen. We digitise recycling yards for cities. Most people will come across the yard as a visitor so this is the visitor version rather than the operator version.
Two failures appear every Saturday and they are not the same failure.
The first is the queue. You load the car, you drive over and the queue's already out on the street. The one piece of information that would have altered the whole trip is the wait time before you even leave the house. In Duisburg Wirtschaftsbetriebe Duisburg do publish a live wait time for the yards so you can see it before you go. A dashboard that only the yard office can see is of no use to anyone on a Saturday.
The second is the container. You're standing there with a bag you're not quite sure about and it goes into the green waste as the opening is facing you. A plastic sack in the branches is a mixed load. The staff will often see it when the container is already full, which is too late for that load. What we see at the green waste containers in Duisburg (the West and North yards amongst others) is a status rather than a video. It's either the wrong item or the container is filling up. A light on the container is sufficient whilst you're still there. Pull that bag back out. The yellow light means the container should be swapped prior to people starting to use the one next to it.
The camera bit - that's the first objection. The image gets processed in the sensor and is then discarded. What remains is 'container 4, misthrow, 11:04' or a fill level. There's no plate, no face, no archive. If a camera on a yard is a no then say so. That use case is the wrong one.
If you actually use a yard, would you check a live wait time before you even got in the car? And if the light at the container told you that the thing in your hand didn't belong there, would that be of any use or would it just feel like you were being policed?
