# 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 30

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

When selenium compounds are used for colouring 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 evaporation of selenium from the batch composition by selecting raw materials with a higher retention efficiency in the glass and reduced volatilisation
The applicability may be limited by the constraints imposed by the type of glass produced at the installation and the availability of the raw materials
(ii)
Applying a filtration system
The technique is generally applicable
(iii)
Applying a dry or semi-dry scrubbing, in combination with a filtration system
Table 20
BAT-AELs for selenium emissions from the melting furnace in the flat glass sector for the production of coloured glass
The values refer to the sum of selenium present in the flue-gases in both solid and gaseous phases.
The lower levels correspond to conditions where the reduction of Se emissions is a priority over a lower production of solid waste from filter dust. In this case, a high stoichiometric ratio (reagent/pollutant) is applied and a significant solid waste stream is generated.
The conversion factor reported in Table 2 (2,5 × 10–3) has been applied.
