Kwinana closure savings lag as Alcoa tackles environmental hurdles with $260M spend
Alcoa is set to invest US$163 million (AU$260 million) in a now-mandatory water management system at its caustic red mud storage site in Kwinana, as savings from the shutdown of its 60-year-old alumina refinery have been slower than anticipated.
The closure, announced in January 2024, was initially expected to cost up to US$200 million (AU$319 million), including US$81 million earmarked for water management and US$55 million allocated for the redundancy or redeployment of 800 employees.
Furthermore, Alcoa intends to spend US$70 million in 2024, preparing for a shift to a new mining area within the Jarrah forest, with more significant investments expected in 2026. This comes as the company continues to face scrutiny in Western Australia (WA) after revelations two years ago that its strip mining activities near Serpentine Dam posed risks to Perth’s water supply.
