Anti-incinerator activists have called for a report into its handling to be finished so lessons can finally be learned from the saga.
County Council officials have admitted there is no date for when the findings of the review will be published, almost two years after it was first commissioned.
But one of the campaigners who led the fight against the Saddlebow scheme believes a line can only be drawn once the review is published.
Michael de Whalley, founder of King’s Lynn Without Incineration (KLWIN), said: “It’s important to know what mistakes have been made, not to apportion blame, but to make sure they’re not repeated.”
But a county council spokesman has confirmed no date has been set for when the report is likely to be released.
Stephen Revell, a former co-leader of the council, was appointed to look at the issue in April 2014, just days after the authority voted to terminate the controversial contract with Cory Wheelabrator.
His remit was to examine how and why the authority found itself in that position, how and why the decision to end the contract was reached and the effect of outside political involvement in helping or hindering the fulfilment of the deal.
The deal, which cost the taxpayer more than £30 million, was stopped after officials warned it would cost more to continue the project.
