Schweizer Salinen AG, Salt production facility in Rheinfelden, Switzerland
Schweizer Salinen AG is a salt production facility in Rheinfelden that extracts salt from underground sources, purifies it, and packages it for distribution. The factory uses evaporation and crystallization processes to produce pure salt for various industrial and consumer purposes.
Salt production in this region began in 1909 when the United Swiss Saltworks on the Rhine was established to centralize national salt production. This foundation was a key step in securing the country's salt supply.
The name Rheinfelden comes from the Rhine river, which shaped the region and made salt extraction possible. Visitors see an important part of Swiss industrial history that remains economically relevant today.
The factory site is accessible on weekdays and offers tours that explain modern extraction processes. Visitors should note that active production areas may sometimes be partially restricted from access.
The facility supplies all Swiss cantons at uniform prices, a system regulated by agreement that ensures equal opportunity across the country. This means every region, regardless of size, has the same access to salt.
