So, let me get this straight.
The brown bin is for green waste whilst the green bin is for brown waste (cardboard), and the blue bin is also a green bin but for neither green or brown waste with the grey bin for everything else.
Does that just about cover it?
In my area, homes only have green, red, blue and black bins. Unless you're in a flat, as those are still allowed to use bags.
However, the red and blue bins are collected on alternating weeks, except for the Christmas period where there's a new timetable and a lot of us start to lose track again.
