It will involve construction of a new manufacturing building and the expansion of the existing warehouse building, laboratory and administration buildings.

“The work of IDA Ireland in helping to attract and secure such investment is essential and it is vital that we continue to create a landscape that is conducive to continued growth. Critical infrastructure projects such as the M28 Cork to Ringaskiddy route must be completed without delay to ensure our region is at the forefront and continues to be enabled to realise its future potential,” he added.
