# Commission Implementing Decision of 28 February 2012 establishing the best available techniques (BAT) conclusions under Directive 2010/75/EU of the European Parliament and of the Council on industrial emissions for the manufacture of glass (notified under document C(2012) 865) (Text with EEA relevance) (2012/134/EU), Division 62

Extent: E+W+S+N.I.

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.
Technique
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.
In glass wool production, the use of manganese in the batch formulation as an oxidising agent depends on the quantity and quality of external cullet employed in the batch formulation and may be minimised accordingly
(ii)
Application of a filtration system
Electrostatic precipitators are not applicable to cupola furnaces for stone wool production (see BAT 56)
Table 52
BAT-AELs for metal emissions from the melting furnace in the mineral wool sector
The ranges refer to the sum of metals present in the flue-gases in both solid and gaseous phases.
The conversion factors of 2 × 10–3 and 2,5 × 10–3 have been used for the determination of the lower and upper values of the BAT-AELs range (see Table 2).
Higher values are associated with the use of cupola furnaces for the production of stone wool.
