# Commission Implementing Decision (EU) 2016/1032 of 13 June 2016 establishing best available techniques (BAT) conclusions, under Directive 2010/75/EU of the European Parliament and of the Council, for the non-ferrous metals industries (notified under document C(2016) 3563) (Text with EEA relevance), Division BAT 49

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

In order to reduce SO2 emissions (other than those that are routed to the sulphuric acid or liquid SO2 plant or power plant) from primary and secondary copper production, BAT is to use one or a combination of the techniques given below.
Technique
Applicability
a
Dry or semi-dry scrubber
Generally applicable
b
Wet scrubber
Applicability may be limited in the following cases:
very high off-gas flow rates (due to the significant amounts of waste and waste water generated)
in arid areas (due to the large volume of water necessary and the need for waste water treatment)
c
Polyether-based absorption/desorption system
Not applicable in the case of secondary copper production.
Not applicable in the absence of a sulphuric acid or liquid SO2 plant
BAT-associated emission levels: See Table 6.
Table 6
BAT-associated emission levels for SO2 emissions to air (other than those that are routed to the sulphuric acid or liquid SO2 plant or power plant) from primary and secondary copper production
As a daily average or as an average over the sampling period.
In the case of using a wet scrubber or a concentrate with a low sulphur content, the BAT-AEL can be up to 350 mg/Nm3.
Parameter
Process
BAT-AEL (mg/Nm3)
SO2
Primary copper production
50-500
Secondary copper production
50-300
