## Capacity and output of the group companies’ plants

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.

| Metal | Stage | capacity / output | Unit | Plants in total |
|---|---|---:|---|---:|
| aluminium | primary aluminium smelter | 1,309 (capacity) | kt/rok | 6 |
| aluminium | secondary aluminium and foundry alloys | 260 (capacity) | kt/rok | 4 |
| aluminium | remelt and wrought-ingot casthouse | 709 (capacity) | kt/rok | 7 |
| aluminium | extrusion plant | 112 (capacity) | kt/rok | 5 |
| aluminium | scrap recycling | 96 (capacity) | kt/rok | 2 |
