The former Molex plant in the Shannon industrial estate, which finally closed last Friday after 49 years of business, is expected to be fully occupied by two new companies by the middle of this year.
The Irish medical devices and technology company Aerogen, which is based in Galway, has agreed to occupy half of the industrial building and have 35 employees on site.
The company, which employs 200 people in Galway, manufactures acute care aerosols for respiratory patients across the world. It had been one of Molex's own clients, and is expected to bring another 80 employees onto the site by the end of this month.
The Molex industrial building has been rehabilitated by the UMR group based in Limerick, which is involved in the metals recycling and site reconfiguration business.
Tony Donlon, one of the partner families in UMR, says they expect to have contracts signed shortly with a second company which they say will be on site by the second half of this year, and which he anticipates could lead to a further 150 employees.
The UMR company is also involved in the repurposing of the Avara pharmaceutical plant, also in Shannon, which closed in 2019 as a result of insolvency.
Mr Donlon added they are well advanced in terms of the occupancy of that plant and its reconfiguration as a manufacturing location, and expect it also to be occupied in the second half of this year.
