Our Business

Recycle, Recover, Dispose

It all started with our underground waste disposal plant. Since then, we have also become specialists in underground recovery. Our comprehensive service for the secondary aluminium industry and building material recycling for the greening of potash tailings piles completes our range.

Maintenance-free Solutions

The geological conditions in our mines are ideal. Rock and salt layers several hundred metres thick separate your waste from the biosphere safely and maintenance-free.

Certified Quality

DIN ISO 9001 and EfbV certified. Regular inspections ensure that our processes and our partners meet the high quality standards of K+S.

Help at all Stages

Upon request K+S can take on and coordinate everything from initial analysis to transport. We also handle large projects quickly and flexibly.
