A steam recycling technology offers a promising option to reduce emissions from Australia's alumina refineries. Alcoa will go ahead with trialling a steam recycling technology aimed at reducing emissions, after a study found the technology was feasible. In 2021, Arena, the Australian Renewable Energy Agency, provided A$11.3 million for a feasibility study looking at the technical and commercial viability of integrating mechanical vapour recompression (MVR) powered by renewable energy in Australian alumina refining processes. Now, the results of the study are in and it is good news.
