Ordered, recorded and potentially retrievable deposition of various types of hazardous wastes (excluding radioactive, explosive, burnable, or infectious wastes) Multi barrier concept with

1.) ordered stacks of lined steel drums, steel containers or big bags,

2.) compartment brick walls between dissimilar waste types,

3.) 6m brick wall/anhydrite dam per large deposit field with approx 3.1 Mio. tons of waste,

4.) 48m dam against conventional potash mine,

5.) gravel and clay filling of the 800m access shaft after closure.
