I suspect there are teething problems, for people and the council alike. If you’ve always been used to weekly collections, it might take some adjustments for the bi-weekly collections. If you are going over, where do you store your rubbish? You can’t store it outside as the foxes will rip it apart. We use to fill up our black bins full each week, when we got he bigger recycling bins this helped, and the brown bins also now help so we’ve managed ok.
Once the bins are overflowing I think they are normally not collected, however I hope for the next few weeks they will be. I’m not sure what people are supposed to do in this circumstance to get rid of the rubbish.
I have a bit more sympathy for the bins in the photos above than I might normally. I would not leave my bin like that but different people have different circumstances and you can get caught up, especially the first few weeks of a change.
And as I have posted in this tread we are still waiting for our food bins!
As an aside I like the system they have in Paris I witness this year. One day (each week I think, maybe each month) you can leave whatever you like pretty much outside your house on the street and it’s collected (furniture, mattresses etc). I think some is recylced by people taking it, but I think it also reduces flytipping for some items. It does not look amazing all the time I’m told, but seems to work well.
