K+S Presents Key Pillars of Overall Strategyl

Today, K+S presented the key pillars of its overall strategy for reducing the burden on the environment to the “Water Protection Werra/Weser and Potash Production” Round Table. In this regard, the Company is pursuing, by means of a package of measures with a value of 360 million euros, its consistent goal of minimising saline waste water, ending the injection of liquid residues and reducing the injection of saline water into the Werra. K+S is currently reviewing a long-distance pipeline concept. A decision on its construction will depend on ecological, political and economic criteria.

Water Report spells it out:
The Werra and the Weser are on the mend – but the challenge is to all

The findings of a long-term study, which is to estimate the effects of changed saline water discharges into the Werra, have now been presented to the authorities of Hesse and Thuringia. The report proves that the biological and ecological state of the Werra has considerably improved and that further key improvements are to be expected through K+S' package of measures designed to protect the water.

Trial for evaporation plant begins

On 1 December 2008, K+S KALI GmbH is starting a trial at the Werra plant concerning the evaporation of saline water from potash produc-tion. The purpose of the trial is to obtain further findings for the techni-cal design of the evaporation plant planned at the Unterbreizbach site.

K+S presents comprehensive package of measures for the protection of waters

K+S has decided on a comprehensive package of measures for the Hessian-Thuringian potash district. K+S will thus significantly reduce the current volume of saline water starting from 2011 already, and gradually halve it to 7 million cubic metres a year by 2015 at the latest. The K+S package of measures will clear the way for gradually reducing the chloride threshold of the Werra, applicable until 2012, from currently 2,500 mg/l to 1,700 mg/l and the hardship threshold from 90 to 65 dH (degrees of German hardness), as well considerably reducing the volume of injected saline water.
