# 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 58

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

When nitrates are used in the batch formulation for glass wool production, BAT is to reduce NOX emissions by using one or a combination of the following techniques:
A description of the techniques is given in Section 1.10.2.
Technique
Applicability
(i)
Minimising the use of nitrates in the batch formulation
The use of nitrates is applied as an oxidising agent in batch formulations with high levels of external cullet to compensate for the presence of organic material contained in the cullet
The technique is generally applicable within the constraints of the quality requirements for the final product
(ii)
Electric melting
The technique is generally applicable.
The implementation of electric melting requires a complete furnace rebuild
(iii)
Oxy-fuel melting
The technique is generally applicable.
The maximum environmental benefits are achieved for applications made at the time of a complete furnace rebuild
Table 48
BAT-AELs for NOX emissions from the melting furnace in glass wool production when nitrates are used in the batch formulation
The conversion factor of 2 × 10–3 has been used (see Table 2).
The lower levels of the ranges are associated with the application of oxy-fuel melting.
