BAT is to reduce metal emissions from the melting furnace by using one or a combination of the following techniques:
| A description of the techniques is given in Sections 1.10.5 and 1.10.6. | |
| Techniquef1 | Applicability |
|---|---|
| (i) Selection of raw materials for the batch formulation with a low content of metals | The technique is generally applicable within the constraints of the availability of raw materials |
| (ii) Applying a dry or semi-dry scrubbing, in combination with a filtration system | The technique is generally applicable |
| (iii) Applying wet scrubbing | The technique is generally applicable within technical constraints; i.e. need for a specific waste water treatment plant. |

BAT-AELs for metal emissions from the melting furnace in the continuous filament glass fibre sector
| The levels refer to the sum of metals present in the flue-gases in both solid and gaseous phases. | ||
| The conversion factor reported in Table 2 (4,5 × 10–3) has been applied. | ||
