Manchester City Council has proposed changes to its collection services in a bid to increase recycling rates and save money.
The proposed changes are to be debated on 21 June with a final decision by the executive committee on 29 June. It is expected the move would save £2.4m a year on waste disposal costs by increasing the recycling rate.
If approved, residents would have their current 240-litre black bins replaced with 140-litre grey bins from August onwards until the end of the year.
Seven other Greater Manchester authorities are already in the process of adjusting their collection services.
Manchester spent £36m on waste disposal in 2015-16 due to its low recycling rate of 33%, the lowest in Greater Manchester. In comparison, neighbouring Trafford recycles 62% of waste and it is 61% in Stockport.
It is estimated that, if recycling rates do not increase, this figure could become £45m during the next few years.
Executive member for neighbourhoods Nigel Murphy said: “When recyclable waste is put into the wrong bin, money is being needlessly thrown away.
“Taking this action to boost Manchester’s recycling rates now will save the city almost £2.5m every year in waste disposal costs, helping to protect the vital council services that residents care about for the long-term future, while also helping the environment.
“Doing nothing is not an option. We are determined to work with residents to ensure that as much waste as possible is recycled.”
Collections are to remain fortnightly and residents who require additional recycling bins will get them at no extra cost. The new bins will also feature a serial number that could be traced to reduce loss or theft, although there is no current plans to activate them.
