each year instead of using the stationary energy consumption data
used in previous studies. Furthermore, the Comparative Life Cycle
Assessment of the Copper Production Process described by the
Commonwealth Scientific and Industrial Research Organization
(Norgate, 2001) as well as the Life Cycle Assessment of Aluminum
described by the International Aluminum Institute (International
Aluminum Institute, 2008) is used for reference and as supplement.
