The small village of Hem in the southern part of West Frisia established its own dairy plant in the early 1900s to streamline the condition of making cheese and other dairy products in the Zuiderkogge Polder. Farmers who supplied the plant with milk had each their share in the products and profit. The ‘Coöp.‘ abbreviation stands for ‘cooperation’.
Volharding can be translated as ‘perseverance’. The postwar building and especially its chimney still dominate the skyline of Hem in 2019.
