# 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 20

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

BAT is to reduce HCl and HF emissions from the melting furnace (possibly combined with flue-gases from hot-end coating activities) by using one or a combination of the following techniques:
A description of the techniques is given in Section 1.10.4.
Technique
Applicability
(i)
Selection of raw materials for the batch formulation with a low content of chlorine and fluorine
The applicability may be limited by the constraints of the type of glass produced at the installation and the availability of raw materials
(ii)
Dry or semi-dry scrubbing, in combination with a filtration system
The technique is generally applicable
Table 10
BAT-AELs for HCl and HF emissions from the melting furnace in the container glass sector
The conversion factor for general cases, reported in Table 2 (1,5 × 10–3) has been applied.
The higher levels are associated with the simultaneous treatment of flue-gases from hot-end coating operations.
