No emissions from waste material are inventoried. Operators claim absolute long-term safety after closure. Non-zero risk of mine flooding remains.
[The full documentation of this dataset was originally provided in the corresponding ecoinvent report from the Swiss Centre for Life Cycle Inventories, which is accessible for free to guests and users of ecoinvent version 2 ( The dataset may subsequently have been subjected to central changes to the database, as described in the respective change report for each new release.]
Undefined unit processes (UPRs) are the unlinked, multi-product activity datasets that form the basis for all of the system models available in the ecoinvent database. This is the way the datasets are obtained and entered into the database by the data providers. These activity datasets are useful for investigating the environmental impacts of a specific activity (gate-to-gate), without regard to its upstream or downstream impacts.


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.
