Environmental and residential groups in Limerick say they will fight the decision by An Bord Pleanála to grant planning permission for a controversial development at the Irish Cement plant in the city.
The company has been given the green light to burn alternative waste such as used tyres and solvents at their factory in Mungret.
The Irish Cement factory is located in what was once a traditional industrial area on the outskirts of the city.
Today it is home to hundreds of families with three schools in close proximity to one another as well as local public amenities.
The decision by An Bord Pleanála to approve the switch from fossil fuels to alternative waste management has angered local residents.
Claire Keating is one of the organisers of the Limerick Against Pollution (LAP) campaign group.
She said a list of over 100 materials to be incinerated at the Mungret plant includes used tyres, plastics, waste animal tissue and fly ash and bottom ash.
Ms Keating said Irish Cement had eliminated 14 hazardous waste substances from that list.
Despite local opposition to the €10 million development, Limerick City and County Council gave the go ahead for the project in March 2017 subject to a number of conditions, including the granting of a licence by the Environmental Protection Agency.
Irish Cement said that replacing fossil fuels is standard practice throughout Europe and that the planning decision will reduce Co2 emissions and make the factory at Mungret more competitive and economically viable for the future.
An Bord Pleanála said the proposed development is in an established industrial area, but would not affect nearby residential amenities nor endanger public health.
Fianna Fáil Councillor James Collins said that apart from environmental concerns, there was a real threat to future job investment in the region as a result of the planning decision.
Campaigners are organising public meetings and protests in the coming weeks in their bid to have the planning decision overturned.
They have also launched a crowd funding initiative with a view to seeking a judicial review.
