The move aims to boost recycling, save more than £800,000 per year and reduce carbon emissions, the council says.
The proposals were approved by the council’s cabinet yesterday (16 July) and the new collection system will be introduced from the second week in October.
Under the new collection regime, non-recyclable waste will be collected every three weeks rather than the current two.
Bury predicts that reducing collection frequency instead of purchasing newer, smaller capacity bins it can avoid a capital outlay of £1.1m for the 70,000 140-litre-capacity containers needed to keep a fortnightly service.
It says the change could result in net savings of around £862,000 per year from 2015/16.
“It costs Bury £10.2m a year to treat and dispose of waste from grey bins [non-recyclable waste], much of which could be recycled. As in 2011, we need the support of residents to create a greener borough”
Recycling bins will be collected more frequently (every three weeks rather than four), and food and garden waste remains at a fortnightly collection.
Most households will continue to have a collection of at least one type of waste every week.
Councillor Susan Southworth, deputy cabinet member for the environment, said: “Understandably, there has been a lot of interest in these plans since they were made public, and people have been voicing their concerns or support.
“A number of people have raised the question of increased smell from the bins. Any cooked or uncooked food waste should be placed in the brown bin, which is not affected by these changes – it will continue to be collected fortnightly.
“To help make food waste recycling cleaner and easier we also provide a free kitchen caddy and free compostable food liners.
“And there should be no hazard to health if, before going in the grey bin, disposable nappies are folded up, bagged and tied up and the same applies to any animal waste.
“It costs Bury £10.2m a year to treat and dispose of waste from grey bins [non-recyclable waste], much of which could be recycled. As in 2011, we need the support of residents to create a greener borough and make sure that money doesn’t go to waste but rather goes to help support other public services.”
