Capacity and output of the group companies’ plants
Full capacity of the group companies’ plants – the sum of the capacity of operating plants, irrespective of the group’s share in the plant.
| Metal | Stage | Full capacity / Output | Unit | Plants in total |
|---|---|---|---|---|
| aluminium | casthouse | 370.5 capacity | kt/rok | 1 |
| aluminium | sheet, strip and plate rolling mill | 855 capacity | kt/rok | 3 |
| aluminium | dross and salt-slag processing | 50 capacity | kt/rok | 1 |
Totals cover the full capacity (and output) of operating plants owned by the group companies, without taking shares in jointly owned plants into account; capacity attributed to the group by share will be added in the next stage. Only values in the same unit and for the same metal are added up.
