In this chemical company, established in 1912 as the site of a coke plant, sulfuric acid and phosphoric acid were produced starting in 1917. The phosphate ore used as a raw material for this was imported from Morocco. Contaminated gypsum was released as a byproduct. In 1925, phosphoric acid production was taken over by the company that gave its name to the site. Even after multiple takeovers, it is still known by that name. Gradually, a gypsum mountain of considerable dimensions formed, eventually covering an area of ​​80 hectares.

In 1989, a sulfuric acid recovery plant was commissioned. Several acquisitions followed, until the company eventually went bankrupt in 2009. What remained after the bankruptcy was the site, the soil of which was remediated and the buildings were demolished starting in 2013. The gypsum storage facility was sealed following remediation and stabilization work. The site has since been reforested, and space has been allocated for a new business park and a solar panel park.
