# 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 26

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

When nitrates are used in the batch formulation, BAT is to reduce NOX emissions by minimising the use of these raw materials, in combination with primary or secondary techniques. If secondary techniques are applied, the BAT-AELs reported in Table 15 are applicable.
If nitrates are used in the batch formulation for the production of special glasses in a limited number of short campaigns, the BAT-AELs are set out in Table 16.
A description of the technique is given in Section 1.10.2.
Technique
Applicability
Primary techniques:
minimising the use of nitrates in the batch formulation
The use of nitrates is applied for special productions (i.e. coloured glass).
Effective alternative materials are sulphates, arsenic oxides, cerium oxide
The substitution of nitrates in the batch formulation may be limited by the high costs and/or higher environmental impact of the alternative materials

The conversion factor reported in Table 2 for specific cases (2,5 × 10–3) has been applied
