  • How is primary aluminium produced?
  • Primary aluminium is produced by means of electrolytic reduction of alumina. This chapter covers the complete process of primary aluminium production, from the production of alumina from bauxite until the shipment of the aluminium off the facilities. For secondary aluminium production, it covers the whole process starting from the melting of scrap.
  • Can We model aluminium processes outside Europe?
  • Moreover, for the primary aluminium datasets (i.e. produced and consumed in Europe), in order to model aluminium processes (e.g. bauxite mining) taking place outside Europe (see Figure 2-1), global averages process data (i.e. from International Aluminium Institute) have been used [4, 5].
  • What is a direct aluminium process?
  • Direct process: Direct material consumption/use or direct emissions associated with the aluminium processes. The following processes are considered as aluminium processes: Primary production: bauxite mining, alumina production, anode/paste production, electrolysis, casting.
  • What is secondary aluminium production?
  • For secondary aluminium production, it covers the whole process starting from the melting of scrap. This chapter only covers process emissions from primary and secondary aluminium production. In secondary aluminium production, combustion activities also cause emissions. These emissions are addressed in section 1.A.2.b.
