Safe and sound underground
A deep underground repository is being built 330 metres below the surface at the Boliden Rönnskär smelter. It is here where process waste from the plant will be stored indefinitely.
The underground repository is unique. Nowhere else in the world is there an underground repository on the same site as a smelter. With our values as a basis, Boliden made the decision to place all process waste from the smelter in the repository. The installation will begin operation by end/beginning of 2019/2020.
