# 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 34

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

BAT is to reduce SOX emissions from the melting furnace by using one or a combination of the following techniques:
A description of the techniques is given in Sections 1.10.3 and 1.10.6.
Technique
Applicability
(i)
Minimisation of the sulphur content in the batch formulation and optimisation of the sulphur balance
The technique is generally applicable within the constraints of quality requirements of the final glass product.
The application of sulphur balance optimisation requires a trade-off approach between the removal of SOX emissions and the management of the solid waste (filter dust), which needs to be disposed of
(ii)
Use of low sulphur content fuels
The applicability may be limited by the constraints associated with the availability of low sulphur fuels, which may be impacted by the energy policy of the Member State
(iii)
Dry or semi-dry scrubbing, in combination with a filtration system
The technique is generally applicable.
The presence of high concentrations of boron compounds in the flue-gases may limit the abatement efficiency of the reagent used in the dry or semi-dry scrubbing systems
(iv)
Use of wet scrubbing
The technique is generally applicable within technical constraints; i.e. need for a specific waste water treatment plant
Table 24
BAT-AELs for SOX emissions from the melting furnace in the continuous filament glass fibre sector
The higher levels of the range are associated with the use of sulphates in the batch formulation for refining the glass.
The conversion factor reported in Table 2 (4,5 × 10–3) has been applied.
For oxy-fuel furnaces with the application of wet scrubbing, the BAT-AEL is reported to be < 0,1 kg/tonne melted glass of SOX, expressed as SO2.
The associated emission levels are related to the use of 1 % sulphur fuel oil in combination with secondary abatement techniques.
The lower levels correspond to conditions where the reduction of SOX is a priority over a lower production of solid waste corresponding to the sulphate-rich filter dust. In this case, the lower levels are associated with the use of a bag filter.
