Abstract Scope |
Due to its unique combination of properties, demand for aluminium products continues to increase. Global demand for aluminium is projected to grow from 99 million tonnes in 2019 to 172 million tonnes in 2050. This is to meet society’s needs across several sectors including transportation, the built environment, energy infrastructure and packaging. While some of this demand will be met by recycled material, significant volumes of primary aluminium will still be required. Alongside this growing demand for metal, expectations for sustainably produced and responsibly sourced material are also growing. The aluminium industry must continue to adapt and address the key sustainability challenges it faces. This paper draws on the International Aluminium Institute's material flow analyses, life cycle analyses, waste management experience and decades of industry statistics. It will provide an overview of future demand scenarios and the challenges associated with fulfilling growing demand including: raw materials supply, sustainable bauxite residue and spent pot lining management and potential greenhouse gas pathways for the sector. |
