Dunreidy Engineering, based in Kilkenny, provided engineering advice to companies carrying out pilot and commercial plant work for WHEYLAYER.
The project expects to have the first WHEYLAYER-based product on the market within a year.
The Irish firm is one of 14 partners from six countries and carried out research in Ireland and the UK on whey usage and applications and assisted European project leaders on whey availability and locations.
Donal Dunne, joint managing director of Dunreidy Engineering, said it had already contributed to the setting up of a patent for the project.
"We expect to benefit from taking part in the engineering process business and successful exploitation of the ongoing business which will arise in the commercialisation of WHEYLAYER".
