Alcoa and South 32's Worsley Alumina mine bauxite in WA's South-West to produce alumina that is exported to aluminium refineries. The industry is energy-intensive with Alcoa's three refineries powered by gas and Worsley using coal from nearby Collie.
Carbon Emissions
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
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 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
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.
