# 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 65

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

In order to prevent or collect diffuse emissions from electrolytic cells in primary aluminium production using prebaked anodes, BAT is to use a combination of the techniques given below.
Technique
a
Automatic multiple point feeding of alumina
b
Complete hood coverage of the cell and adequate off-gas extraction rates (to lead the off-gas to the treatment in BAT 67) taking into account fluoride generation from bath and carbon anode consumption
c
Boosted suction system connected to the abatement techniques listed in BAT 67
d
Minimisation of the time for changing anodes and other activities that require cell hoods to be removed
e
Efficient process control system avoiding process deviations that might otherwise lead to increased cell evolution and emissions
f
Use of a programmed system for cell operations and maintenance
g
Use of established efficient cleaning methods in the rodding plant to recover fluorides and carbon
h
Storage of removed anodes in a compartment near the cell, connected to the treatment in BAT 67, or storage of the butts in confined boxes
