# 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 22

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

When tin, organotin or titanium compounds are used for hot-end coating operations, BAT is to reduce emissions by using one or a combination of the following techniques:
A description of the techniques is given in Sections 1.10.4 and 1.10.7.
Technique
Applicability
(i)
Minimising the losses of the coating product by ensuring a good sealing of the application system and applying an effective extracting hood.
A good construction and sealing of the application system is essential for minimising losses of unreacted product into the air
The technique is generally applicable
(ii)
Combining the flue-gas from the coating operations with the waste gas from the melting furnace or with the combustion air of the furnace, when a secondary treatment system is applied (filter and dry or semi-dry scrubber).
Based on the chemical compatibility, the waste gases from the coating operations may be combined with other flue-gases before treatment. These two options may be applied:
combination with the flue gases from the melting furnace, upstream of a secondary abatement system (dry or semi-dry scrubbing plus filtration system)
combination with combustion air before entering the regenerator, followed by secondary abatement treatment of the waste gases generated during the melting process (dry or semi-dry scrubbing + filtration system)
The combination with flue gases from the melting furnace is generally applicable.
The combination with combustion air may be affected by technical constraints due to some potential effects on the glass chemistry and on the regenerator materials
(iii)
Applying a secondary technique, e.g. wet scrubbing, dry scrubbing plus filtration
The techniques are generally applicable
