Sorry for the confusion.
There were 4 containers: 2 for glass, 1 for textile and 1 for cooking oil. The latter was an Oliobox indeed but I don't remember the one for textile. It was also a buried style container so I thought it was also Bruxelles Propreté. Should have taken a picture!

I just checked the behaviours of the planner and they now take into account the staircase, so the pedestrian crossing is fixed IMO. I just made another slight modification to simplify further the pedestrian paths, that is to make the path 673052068 access=yes instead of access=private. Indeed, this short section is the public street between the road and the cycle path, before it becomes private (before the gate).

Hello, thank you for the review!
From what I saw on site, the pedestrian path to cross the bridge is the cycle track, because the road is too dangerous without any sidewalk and there's even a little staircase from the east bank "vaartkant-Oost" for the pedestrians to access the cycle track (which is therefore a cycle and pedestrians track as opposed to the loop which looks more cycle-only). I have added "foot=yes" on the "cycle track" above the bridge and on the west part of the track, which is connected later to oudstrijdersstraat. I also have connected the staircase to the bridge and to vaartkant-oost. That should repair the pedestrian routing.
Tell me what you think about it!

I totally agree that tags should be sufficient. My problem might be that the apps I use do not allow this kind of POI search. Do you have any (android) app recommendation for that?
My other problem is that as a naïve user, I would have expected to find what I'm looking for by typing "bulle à verre" which is the typical name used by normal people to designate this place. A tremendous app would be one that is smart enough to translate the common place names into the right osm POI based on their tags. If such app exists, I'm interested!

I admit I haven't read this note and agree it is not the best if search is not robust to plural variation. Would you suggest to type "Bulle à verre" in the "description" field instead (or even "description:fr" ?

Thanks for the clarification. The problem on this section was that previously the routing engines would generate a detour so that bikes would avoid this section. Checking on the tags, I think "bicycle=no" was set (which is incorrect in this case since this section is authorized for bikes just like the rest of the roundabout). According to your explanation, just removing this tag would have been enough instead of changing the "no" into "yes". Is it correct?
