# 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 60

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

BAT is to reduce HCl and HF emissions from the melting furnace by using one or a combination of the following techniques:
A description of the techniques is given in Section 1.10.4.
Technique
Description
(i)
Selection of raw materials for the batch formulation with a low content of chlorine and fluorine
The technique is generally applicable within the constraints of the batch formulation and the availability of raw materials
(ii)
Dry or semi-dry scrubbing, in combination with a filtration system
Electrostatic precipitators are not applicable to cupola furnaces for stone wool production (see BAT 56)
Table 50
BAT-AELs for HCl and HF emissions from the melting furnace in the mineral wool sector
The conversion factors of 2 × 10–3 for glass wool and 2,5 × 10–3 for stone wool have been used (see Table 2).
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).
