# 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 74

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
Applicability
(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)
Minimisation of the fluorine compounds in the batch formulation when used to ensure the quality of the final product
Fluorine compounds are used to confer particular characteristics to the frits (i.e. thermal and chemical resistance)
The minimisation or substitution of fluorine compounds with alternative materials is limited by quality requirements of the product
(iii)
Dry or semi-dry scrubbing, in combination with a filtration system
The technique is generally applicable
Table 64
BAT-AELs for HCl and HF emissions from the melting furnace in the frits sector
The conversion factor of 5 × 10–3 has been used with some values being approximated. A case-by-case conversion factor may have to be applied based on the type of combustion (see Table 2).
