A West Norfolk councillor has claimed officials got it wrong in claiming a plan to ship waste to Holland for burning would cost even more than the incinerator.
A cross-party group of councillors has called for the offer by the Rebel group to take waste at a plant in Amsterdam to be considered by County Hall bosses.
As first reported in the Lynn News last month, supporters argue the plan would cost up to £34 per tonne less than building the Saddlebow plant and could save the county up to £88 million over 25 years.
But, in his briefing to councillors ahead of Monday’s meeting, Peter Timmins, the authority’s interim head of finance, said the Dutch plan could cost as much as £48 per tonne more to implement than the incinerator.
He said: “The cost of termination and re-procurement have to be added to the alternative scheme.”
But UKIP group leader Toby Coke said the report had attributed extra sorting and transport costs which were “totally wrong.”
He also questioned claims that the authority would be left with an asset at the end of the incinerator contract, because of the decline of the sector in Europe and North America.
He said: “We’ll probably have a huge demolition bill.”
