I'm exhausted KatyK, must go for a lie down.
Ours is similar, but they provide polythene bags (surely not eco friendly?). Tins, plastic and glass in one, paper and card in another, a third for general waste. Then there are the bags which we have to pay a levy on annually for garden waste, the small food recycling bin lined with biodegradable bags which goes into the larger food recycling bin outside. Oh, and the clinical waste bags for nappies and other incontinence necessaries. So if you don't have babies in the house all the neighbours know if you have a problem with incontinence as they are brightly coloured!
They changed the colour of the garden bags last year so most people have a load of very large bags made of polypropylene hanging around; we had just bought some new ones and then they changed the system. OK if you have the space, you have to devise other uses for them.
