Auckland Council is asking residents to up their game when it comes to recycling and is putting teams of bin inspectors on the streets to make it happen.
Non-recyclable rubbish incorrectly put in recycling bins costs ratepayers more than $170,000 a year - and can pose a danger to rubbish disposal workers.
"Any rubbish placed in recycling bins has to be processed at high expense at the sorting facility and ends up with the whole load being sent to landfill," says the council's environment and community committee Chair Penny Hulse.
"The level for incorrect materials sits at around 13 per cent for Auckland. Our aim is to get that down to five per cent."
To do that the council has introduced a new initiative involving teams of bin inspectors who check the contents of bins before they're picked up by the recycling truck.
