# 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 44

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

When selenium compounds are used for decolourising the glass, BAT is to reduce selenium 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)
Minimising the use of selenium compounds in the batch formulation, through a suitable selection of the raw materials
The applicability may be limited by the constraints imposed by 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 34
BAT-AELs for selenium emissions from the melting furnace in the domestic glass sector when selenium compounds are used for decolourising the glass
The values refer to the sum of selenium present in the flue-gases in both solid and gaseous phases.
A conversion factor of 3 × 10–3 has been applied (see Table 2). However, a case-by-case conversion factor may have to be applied for specific productions.
