A number of public representatives in Co Mayo have expressed concerns about a proposal to build Europe's first asbestos recycling plant in Killala.
They also say their worries have not been alleviated by a briefing session with the company concerned, Irish Environmental Processes (IEP) Ltd.
Killala Fine Gael councillor Jarlath Munnelly said the people of Killala and Mayo do not want the plant and would fight it every step of the way.
He expressed concern about potential health effects from the plant itself and from the transportation of asbestos from all over Ireland.
Mr Munnelly added that he did not believe company assurances that both the transportation and recycling processes would be safe.
Independent TD Dr Jerry Cowley also expressed concerns about transporting asbestos, which is a cancer-causing substance, from every corner of Ireland to Killala.
Despite the company denying it would process other forms of waste, Dr Cowley said IEP's website said other waste could be disposed of in Killala. He said the process IEP plans to use in Killala is also used for radioactive and other hazardous waste.
The plant is expected to cost €10m and employ 30 workers.
