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 | 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 |
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.
