Here, it alternates between blue wheelie bin (general recycling) and green wheelie bin (garden & kitchen waste). There is a black bag collection every week - we get issued with 52 black bags every October. I might only use eight a year, and even when I do put one out, it's barely half full. Usually, pong wins out over quantity when it comes to the black bag, especially in summer.
Most of what goes in my black bag is cat food pouches as they're not recycled locally. There is a scheme that does recycle them, but the nearest collection point involves a 40-something mile round trip...
