Joint waste project partners Milton Keynes Council and Northamptonshire County Council are moving their bid for private finance initiative (PFI) credits forward.
The partnerships outline business case (OBC) will be presented to the councils cabinet this month for approval. If approved, the OBC will go to the Department for Environment, Food and Rural Affairs (Defra), which will announce in autumn 2008 whether the proposal will go to the next stage.
Both councils expect major population growth, and the resultant household waste increases, over the next 20 years.
Milton Keynes Council head of environmental services Geoff Beck said: We have been encouraged by Defra to consider working with another authority to look at procuring waste treatment and disposal facilities together.
Our discussions with Northamptonshire and a subsequent feasibility study proved positive. We have similar aspirations on managing waste and we are both focused on maximising recycling and composting.
Northamptonshire County Council cabinet member for the environment Ben Smith said: The OBC is the result of a years collaboration between the two authorities to explore the different technologies available to treat residual waste, and to look at the legal and financial benefits of working together.
