# 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 31

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

BAT is to reduce emissions to air from the downstream processes by using one or a combination of the following techniques:
A description of the secondary treatment systems is given in Sections 1.10.3 and 1.10.6.
Technique
Applicability
(i)
Minimising the losses of coating products applied to the flat glass by ensuring a good sealing of the application system
The techniques are generally applicable
(ii)
Minimising the losses of SO2 from the annealing lehr, by operating the control system in an optimum manner
(iii)
Combining the SO2 emissions from the lehr with the waste gas from the melting furnace, when technically feasible, and where a secondary treatment system is applied (filter and dry or semi-dry scrubber)
(iv)
Applying a secondary technique, e.g. wet scrubbing, or dry scrubbing and filtration
The techniques are generally applicable.
The selection of the technique and its performance will depend on the inlet waste gas composition
