Salford City Council approves three-weekly bin collection pilot
Some Salford households will only have their bins emptied once every three weeks under new council-backed plans.
Residents in nine of the city's wards will see their non-recyclable waste - currently collected every fortnight - taken away less frequently from July.
Other collections will not be affected under the plan, which the council hopes will encourage more recycling.
Councillor Gena Merrett said recycling had plateaued at 42%, and that more of it could save the council £1m annually.
"If everyone in the city recycled 22 extra plastic bottles, 17 extra glass jars and 30 more cans a year, it would push recycling rates in the city up by 5%," she said.
"If we don't stop sending so much waste to landfill, we could be looking at spending up to £3.5m more on waste in the next few years."
A council spokeswoman said the authority collects about 6,250 tonnes of waste per month and the cost of sending it to landfill would soon be £325 per tonne.
Recycling earns the council £25 per tonne.
The three-weekly collection pilot will take place in Worsley, Boothstown and Ellenbrook, Irlam and Cadishead, Little Hulton, Swinton North, Swinton South, Pendlebury, Walkden North and Walkden South.
