How can PFC emissions be reduced?
PFCs are emitted during “anode effects” that occur when the alumina ore content of the electrolytic bath falls below critical levels optimal for the production of aluminum. Although PFC emissions cannot be eliminated completely with current technology, emissions can be reduced by lowering the frequency and duration of anode effects. Technological and operational changes like employee training, use of computer monitoring, and changes in feeding techniques are used to minimize anode effects without sacrificing competitiveness.
