A new tagging system to encourage households to put items in the right bins and stop overflowing containers, is being rolled out in Belfast.
The tag will explain how to dispose of waste properly.
Belfast City Council has said it will also make it safer for operators to empty bins into lorries on collection day.
From Monday bins which breach the new rules will receive a ‘first warning’ amber tag.
From 29 September, red tags will be issued for bins which continue to overflow, or have a liner. Those bins will not be collected.
Councillor Ruth Brooks said other councils already follow similar guidelines.
“While our crews have always done their best to support households on collection day, we need to take a consistent approach to how bins are presented and emptied city-wide,” she added.
