I love in a flat, so externally I have 6 massive bins - 2 brown, 4 black (recycling and general waste, respectively). I do separately collect my green waste but, until the food waste collections return (it went, they threatened a blu bin for glass which no-one wanted and they offered the return of food waste collection again at some point), it just goes in the grey bins (I largely do it because my main inside bin doesn't fill up much and this stops it from being minging). I have an Addis bin for recycling and separately collect tetra paks, blister packs, plastic bags and batteries to all go off to their respective recycling locations.

My brother has 6 normal-size wheelie bins:

• 3 x black - general
• 2 x brown - recycling
• 1 x green - garden waste

They were there when he moved into their new house and, as there are only four of them, they are under-utlising the bins.
