New ways to help provide multi-million pound waste collection services in Northamptonshire are being sought by the county council.
Ideas are being called for after the council's £138m joint Private Finance Initiative (PFI) with Milton Keynes Council was scrapped by the government.
The council is looking for firms and groups interested in how best to deal with household and business waste.
More information on the consultation is on the council's web site.
Northamptonshire County Council is beginning a project which will result in new contracts for residual municipal waste in the county.
The project will look to identify interested organisations and their specific areas of experience and expertise as well as understand what solutions might be possible.
Heather Smith, county council cabinet member for highways, said: "The amount of residual waste produced in the county is increasing, with estimates that it could rise to over 200,000 tonnes a year by 2020.
"The financial and environmental problems associated with landfill are not going away so we are instead looking for the most cost effective, sustainable solutions for the taxpayers of Northamptonshire."
