Paste 2018 Site Visit – Alcoa of Australia’s Kwinana Bauxite Residue Storage Area – SOLD OUT

Saturday 14 April 2018 | Kwinana Bauxite Residue Storage Area, Western Australia

Alcoa commissioned an innovative technology known as residue filtration at Kwinana Refinery in 2016. With this technology, bauxite residue generated from the alumina refining process is forced through very large filters that squeeze out the waste water, which is recycled in the refining process. The filtered material allows for more efficient utilisation of existing residue areas, deferring the need to build new areas. The water recovered from filtration also significantly reduces the refinery’s freshwater needs. Alcoa continues to evaluate the potential use of this technology at other refineries around the world with construction of a filtration plant at the company’s Pinjarra Refinery in Western Australia’s Peel region underway.


The ACG thanks Alcoa of Australia for freely donating their time and resources to host this visit.

This site visit is now SOLD OUT.
