Northamptonshire County Council waste contracts set to save £5.7m
New contracts to reduce the amount of rubbish sent to landfill in Northamptonshire would save £5.7m over seven years, the county council says.
It spent more than £12m dumping 140,000 tonnes of waste in landfill this year.
The Conservative-run authority said it needed to reduce the amount of landfill waste as costs were increasing.
Councillors will be given an update on the project at a meeting on 11 December.
The contract for the four companies who currently dispose of waste for the county council will end in March 2013.
Northamptonshire County Council said the cost of dumping non-recyclable waste into landfill was set to rise from £85 to £105 per tonne by 2014/15.
And this would increase further to £134 per tonne by 2019/20, which would mean the council would have to spend up to £23m each year to dump waste.
Ben Smith, cabinet member for the environment, said: "This shows that we're taking positive steps to reduce the amount of non-recyclable waste which is land-filled by using innovative solutions.
"Northamptonshire County Council isn't investing in new facilities, but making full use of the facilities that the waste management industry offers."
The council would award three new contracts which it said would divert up to 65% of waste going to landfill.
Northamptonshire County Council said it had to find a new scheme to reduce the amount of non-recyclable waste, after a joint waste disposal scheme with Milton Keynes called "Project Reduce" did not go ahead.
