An industrial cleaning services factory based in Syngefield Industrial Estate, Birr, Co Offaly is to close with the loss of 36 jobs.
Following a 30-day consultation with staff, Nanoclean has decided to close.
According to a company spokesperson, the business is currently now involved in an industrial relations process on redundancy terms.
In November last year, fears grew for the future of the business and it was reported that 14 workers were temporarily laid-off at the plant with the remainder being restricted to part-time work.
In February a further seven employees were also temporarily laid-off.
In a statement, management said "the increasing demands of the cleanroom industry have brought into questions the ongoing viability of the plant".
Nanoclean launders garments for the pharmaceutical industry and is run by UK company Berendsen and has been in Birr for 20 years.
According to the Berendsen website the company has its Irish headquarters in Dún Laoghaire along with facilities in Stillorgan in Dublin, Roscommon, Limerick and Millfield amd Glanmire in Cork.
