  • It all began in 1911 1911
    It all began in 1911. Sam Van den Bergh & Anton Jurgens decided to build a soap & hardening factory. And a vegetable oil factory in Zwijndrecht. In 1913 the first production started. In 1915 Jurgens began a new oil refinery with a capacity of 400 tons a week at Zwijndrecht.

    In 1915 Jurgens began a new oil refinery with a capacity of 400 tons a week at Zwijndrecht. In 1927 Van den Bergh and Jurgens decided to merge its activities on margarine and oil refinery. The result: the N.V. Maatschappij der Vereenigde Oliefabrieken (MVO) at Zwijndrecht and the Margarine Union.
  • Elected to UNEP 1992
    Clearing land by felling and chipping off old trees, and leaving them to decompose on the ground, is the gold standard of practice for most established palm oil companies today. It was accorded the United Nations Environment Programme's (UNEP) Global 500 Roll of Honour for Environmental Achievement during the Rio Earth Summit in 1992.
  • A new merger of the Dutch Margarine Union 1929
    In 1929 there was a new merger of the Dutch Margarine Union, the English Margarine Union and Lever Brothers Ltd, from which the Lever Brothers & Unilever was founded. This merger was later renamed in Unilever N.V. The N.V. Maatschappij der Vereenigde Oliefabrieken at Zwijndrecht became a subsidiary of Unilever N.V. Rapid modernization took place between 1965 and 1980 where most labour-intensive task was replaced with automation. In the 1970’s MVO was assigned to be part of the German division of Unilever and as a result, a more international name - Unimills BV- was created to replace its old name.
