A €126 million investment is to be ploughed into a north Kilkenny site by Tirlán.
Plan is for a state-of-the-art processing facility in Ballyragget which will focus on the production of an advanced nutritional whey protein product portfolio, including clear whey protein.
The plant, which also aims to be water neutral and carbon efficient, is expected to be operational by mid-2027.

The Agriculture Minister Martin Heydon was present for the announcement earlier and said; “Today marks another milestone in the proud history of Tirlán and the Ballyragget site which has been synonymous with dairy innovation for many years now. This multi-million-euro investment in whey protein processing capability represents not just a commitment to Tirlán’s future, but to the Irish dairy industry as a whole. Whey has transformed from what was once considered just a by-product of cheese making into one of the most valuable and versatile nutritional ingredients in the world. Our grass-based milk production, traceability standards, and processing innovations give us a strong competitive advantage as international demand for whey ingredients continues to grow across sports nutrition, lifestyle products, infant formula and medical nutrition.”
Tirlán Chief Executive Seán Molloy said; “This investment enables us to diversify our product mix, ensuring we remain relevant in a changing and growing market. It will deliver a product portfolio to support our customers’ evolving needs.”
He highlighted the critical role of the R&D programme at Tirlán’s Innovation Centre in this investment. “Every product is driven by consumer insights and R&D excellence, ensuring relevance and impact.”
