The public company Wester Suikerraffinaderij N.V., which held shares in CSM, survived into the 1990s.

The Wester Suikerraffinaderij was founded in the long tradition of Amsterdam as a world center for refining sugar.

The supervisory board consisted of D. Cordes, B. van Marwijk Kooy, S. de Clercq Willemszoon, and M.C.

[6] In 1908 the success of the cooperative beet sugar factories led to the foundation of the Algemeene Suiker Maatschappij (ASMij).

This was a merger of the sugar factories: Paul Wittouck in Bergen op Zoom; De Mark in Oudenbosch; and the one in Breda.

This time, the Wester, Hollandia dairy company, and the partnership Van Loon, De Ram & Co. founded a new company called Centrale Suiker Maatschappij (CSM), with a share capital of 30,000,000 guilders.

At first, the public company N.V. Wester Suikerraffinaderij became the majority shareholder in CSM, holding 6,600 of the 12,000 regular shares.

[3] A development that was especially dangerous to the refinery was that the United Kingdom started to protect and subsidize its own sugar beet industry.

After World War II CSM achieved record production figures for sugar from beet.

It focused on export, but after profiting from the high sugar prices in the years after the war it got into trouble when these fell rapidly after 1951.

[3] The beginning of the end came when in September 1960, the government stopped to repay Wester for the import tariff that was levied on raw cane sugar.

[15] By 1962 refining raw cane sugar was no longer profitable at the Wester, and in September of that year 200 employees were fired.
