At the chemical plant in Rüdersdorf the GDR produced until the end of 1999 the phosphate for feedstuffs “Rükana” (de-fluorinated crude phosphate), which was mainly sold to the West. Of the total of 500 employees, only 12 were employed in 1999. In early 2000, the company filed for bankruptcy and ceased production.
After the closure, the factory once again attracted attention by an environmental scandal: In the still intact, but unsecured chemical laboratories leaking containers with highly toxic chemicals were stored, the contents of which ran off uncontrollably into the ground.
