We used to have a green wheelie bin for landfill, a large red and blue box for recycling and a brown for garden. But now we have a small blue for landfill, the green is now recycling, a black one for food, the brown for garden and the blue box for glass and small electrical.
And if at any time there is something in a bin that the collectors do not like then it will remain unemptied until you can figure out what is in there that upsets them as they do not leave any clues to the offending item. Lets us not forget it is our job to move them up a small flight of stairs along a corridor down another small flight of stairs and place them neatly at the curbside. It is their job to empty them and then leave them in a muddle blocking the pavement. Should anything drop from the bin it is not the collectors job to pick it up, health and safety don't you know?
And no they do not get cleaned.
