Abstract
This project aims to assess the environmental impact of aluminium production
processes using a life cycle assessment approach. The life cycle approach is applied to
the product path from the raw material extraction to the time they are disposed or
recycled. Several manufacturing processes were presented and their LCI and life cycle
impact assessment are outlined and analyzed. The results of the study revealed that
energy production is responsible for the highest percentage of emissions since most of
the energy demanded results from non-renewable sources. In light of these findings, it
was recommended that an improvement in the production technology would reduce the
primary energy demand, which in turn would reduce emissions into the environment.
Consequently, mitigation of the effect of the emissions on the environment would be
achieved. In addition, the promotion of recycling of aluminium products would greatly
assist in reducing primary energy demand and hence emissions.
