"The government is allowing Alcoa to do whatever they friggin want," according to a long-term campaigner for better regulation of WA's alumina refineries.
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.
WA will be home to two of the largest green hydrogen electrolysers in the world to feed an ammonia plant and inject the clean fuel into the South West gas grid.
