Overview

Life cycle assessment reveals significant environmental impacts of bauxite residue management practices, indicating potential for sustainability improvements.

Key Points

  • Environmental impacts decrease by 21.6–77.7% when using drying and valorization compared to wet disposal.
  • Dry disposal combined with geopolymer manufacturing presents the lowest environmental impact while increasing cumulative energy demand.
  • The study identifies key environmental challenges in current bauxite residue practices and opportunities for efficiency.
  • Global warming reduction is limited to 12.8%, highlighting the need for improved management strategies.
