A new audit of the Poolbeg Incinerator is being described as a damning indictment of the project.
The report criticises Dublin City Council for allowing it run way over-budget.
The project has cost the taxpayer more than €80 million to date.
That is despite the controversial waste energy project never getting off the ground.
Spiraling costs
The Dublin Waste to Energy project is a public-private partnership between Dublin City Council and Dublin Waste to Energy Ltd.
The aim is to provide a treatment plant to treat approximately 25% of waste that cannot be reused or recycled.
The plant is set to generate energy from up to 600,000 tonnes of waste per year that would otherwise go to landfill and will reporedly generate enough electricity for up to 50,000 homes annually.
But in one area costs are believed to have spiraled from a projected €8.3 million to an actual cost of over €28 million.
The audit only covers the period up until December 2011 which means the true cost could be even higher.
Speaking to 98FM Councillor Mary Fitzpatrick accused the council of mis-managing public money.
