Alumina in WA

Alcoa to test new steam tech in WA that could cut emissions 70pc

Alcoa will trial technology at its Wagerup alumina refinery to produce steam by renewable-powered compression instead of gas-fired heat that promises a 70% per cent emissions reduction.

Carbon Emissions

South32's coal-fired Worsley Alumina two-thirds dirtier than Alcoa

If South32’s low profile coal-burning Worsley Alumina operated like Alcoa’s facilities 1.5 million tonnes of carbon emissions a year would be avoided: the same as Alcoa's Wagerup refinery.

Carbon Emissions

WA’s top carbon polluters: LNG, power, iron ore and alumina

WA's industrial greenhouse gas emissions are dominated by four products and a handful of companies, including a few that have managed to keep a low profile in the climate wars.

Analysis

Lost: one lime contract and $645M

No deal with Alcoa has cost Adelaide Brighton 31% of its value and threatened its WA lime business that is warring with its neighbours in suburban Perth.
