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 Section 1.10.5. | |
| Techniquef1 | Applicability |
|---|---|
| (i) Selection of raw materials for the batch formulation with a low content of metals | The applicability may be limited by the constraints imposed by the type of glass produced at the installation and the availability of the raw materials. |
| (ii) Applying a filtration system | The technique is generally applicable |
| (iii) Applying a dry or semi-dry scrubbing, in combination with a filtration system | |

BAT-AELs for metal emissions from the melting furnace in the flat glass sector, with the exception of selenium coloured glasses
| The ranges refer to the sum of metals present in the flue-gases in both solid and gaseous phases. | ||
| The conversion factor reported in Table 2 (2,5 × 10–3) has been applied | ||
