Off-the-charts marine heat severely damages Ningaloo and other pristine coral reefs
Luck has run out for WA's coral reefs, with most under twice the level of heat stress that can kill coral. Climate change is the cause.
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 mining in the jarrah forest is facing significant opposition on environmental grounds.
Australia's most gas-dependent state has flipped from promising cheap abundance to facing expensive shortages in just six years: investors beware.
WA's environmental watchdog will consider the risk to Perth's water supply and whether the US miner can rehabilitate the forest it strip-mines.
Destroyed forest. Threatened water supply. Toxic towns. Mountains of residue. Will the WA Government demand better?
Kwinana and Yarloop have suffered from Alcoa's toxic dust - is Pinjarra next?
Two journalists from Alcoa's hometown flew to Perth to look at its mining of WA's jarrah. A brilliant look at a slow-moving tragedy.
Costly, complex, and with old technology, the 60-year-old alumina refinery that had employed 800 workers is unlikely to reopen.
The US miner expects WA government approval within 12 months to destroy 75 square kilometres of jarrah forest to enable its "number one" lever to boost profits.
The 2022 incident is one of many at Alcoa's three refineries that are under an increased level of surveillance from the work safety regulator.
The cost of managing water where it stores 140 million tonnes of caustic red mud has doubled.
The US firm is cleaning up caustic liquid after a power loss and working to restore full production at its largest alumina refinery.
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.
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.
