Dublin City Council has said that a new incinerator will be required to meet the country's waste management needs.
The city council, which is the lead authority for the East and Midlands Region (EMR), says an investment of €600 million in total is needed nationally.
This is in addition to the Poolbeg incinerator.
The region, which covers 12 local authorities and more than half of the country's population, is aiming to cut waste by 6% by 2021 and increase recycling rates from 40% to 50%.
But it states that national waste management will require €360 million of public funding over the next six years and €300m from the private sector to include a new 300,000 tonne incinerator and facilities to dispose of organic and hazardous waste.
The Poolbeg incinerator will open in 2018, with a capacity for 600,000 tonnes of waste.
The Irish Waste Management Association now supports the incinerator, although in the past the organisation had opposed it, saying it was too big and would reduce recycling.
Dublin City Council says the incinerator will cater "predominantly" for the Dublin region according to its planning permission.
But Kieran Mullins of the IWMA said his members expect it to also cater for other counties in the EMR - Kildare, Louth, Laois, Longford, Meath, Offaly, Westmeath and Wicklow.
The waste management plan announced today will cover the years 2015 to 2021.
