Effective alternative materials are sulphates, arsenic oxides, cerium oxide\nThe substitution of nitrates in the batch formulation may be limited by the high costs and/or higher environmental impact of the alternative materials\nTable 40\nBAT-AELs for NOX emissions from the melting furnace in the special glass sector when nitrates are used in the batch formulation\nThe lower levels are associated with the use of electric melting.\nThe conversion factors of 2,5 × 10–3 and 6,5 × 10–3 have been used for the determination of the lower and upper value of the BAT-AEL range respectively, with values being approximated. A case-by-case conversion factor may have to be applied based on the type of production (see Table 2).\nParameter\nBAT\nBAT-AEL\nmg/Nm3\nkg/tonne melted glass\nNOX expressed as NO2\nMinimisation of nitrate input in the batch formulation combined with primary or secondary techniques\n< 500 – 1 000\n< 1 – 6",
