# 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 11

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

BAT is to reduce boron emissions from the melting furnace, when boron compounds are used in the batch formulation, by using one or a combination of the following techniques:
A description of the techniques is given in Sections 1.10.1, 1.10.4 and 1.10.6.
Technique
Applicability
(i)
Operation of a filtration system at a suitable temperature for enhancing the separation of boron compounds in the solid state, taking into account that some boric acid species may be present in the flue-gas as gaseous compounds at temperatures below 200 °C, but also as low as 60 °C
The applicability to existing plants may be limited by technical constraints associated with the position and characteristics of the existing filter system
(ii)
Use of dry or semi-dry scrubbing in combination with a filtration system
The applicability may be limited by a decreased removal efficiency of other gaseous pollutants (SOX, HCl, HF) caused by the deposition of boron compounds on the surface of the dry alkaline reagent
(iii)
Use of wet scrubbing
The applicability to existing plants may be limited by the need of a specific waste water treatment
