If you put a glass bottle into where the aluminium cans are supposed to go, Hope Lawsen will know all about it.
The 26-year-old is a recycling ambassador and is being stationed at litter hotspots around the Mount this summer to advise the public how to put their litter in the right place.
Lawsen was one of many ambassadors who hoped to educate residents, cruise ship passengers and other summer tourists about the importance of using rubbish and recycling bins, and which items can be placed in which bins.
Lawsen said there were 10 new smart technology waste and recycling bins installed at Mount Maunganui in early December to help tackle overflowing litter bins during the busy summer period.
"The smart bins can sense when the bin is three-quarters full and send a message to the council to say they need emptying," she said.
