Tirlán

Tirlán (known as Glanbia Co-operative Society Limited from 1997 until 2022) is an Irish dairy co-operative. The co-operative has its roots in a series of amalgamations of small rural co-operative creamery societies throughout County Kilkenny, most notably the amalgamation of Avonmore Creameries Federation in 1966.

Prior to the full takeover of Glanbia Ireland, the primary activities of the co-operative had been managing the co-operatives investments for the benefit of its farmer-members.
