# 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 43

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

BAT is to reduce metal 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)
Selection of raw materials for the batch formulation with a low content of metals
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)
Minimising the use of metal compounds in the batch formulation, through a suitable selection of the raw materials where colouring and decolourising of glass is needed or where specific characteristics are conferred to the glass
For the production of crystal and lead crystal glasses the minimisation of metal compounds in the batch formulation is restricted by the limits defined in Directive 69/493/EEC which classifies the chemical composition of the final glass products.
(iii)
Dry or semi-dry scrubbing, in combination with a filtration system
The technique is generally applicable
Table 33
BAT-AELs for metal emissions from the melting furnace in the domestic glass sector with the exception of glasses where selenium is used for decolourising
The levels refer to the sum of metals 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.
