Conventional methods of bauxite residue rehabilitation require expensive and unsustainable covering topsoil. Building on recent breakthroughs in eco-engineering tailings into soil, the project aims to develop a field-based technology using marine microbes and halophytic plants to accelerate in-situ soil formation from bauxite residues (incl seawater neutralised bauxite residues) under field conditions. The technology will be underpinned by understanding the roles of marine microbe consortia and eco-engineering inputs in accelerating key mineralogical, geochemical, physical and biological changes in bauxite residues. This technology is expected to be transferable and adaptable across other alumina refineries in Australia.Read moreRead less
Eco-engineering soil from mine tailings for native plant rehabilitation. Eco-engineering soil from mine tailings for native plant rehabilitation. This project aims to develop integrated and low-cost eco-engineering technology to purposefully accelerate in-situ formation of soil from tailings for sustainable native plant community rehabilitation at metal mines. Soil shortages at mines cost the Australian mining industry billions of dollars in sustainable rehabilitation of tailings, and threaten t ....Eco-engineering soil from mine tailings for native plant rehabilitation. Eco-engineering soil from mine tailings for native plant rehabilitation. This project aims to develop integrated and low-cost eco-engineering technology to purposefully accelerate in-situ formation of soil from tailings for sustainable native plant community rehabilitation at metal mines. Soil shortages at mines cost the Australian mining industry billions of dollars in sustainable rehabilitation of tailings, and threaten the industry’s ecological and commercial sustainability. Building on recent findings of critical processes in soil formation from copper/lead–zinc tailings, this research will use key biogeochemical and rhizosphere processes in the tailing-soil to create a functional 'technosol'. This technology is intended to be used in Australian metal mines to offset the soil needed to rehabilitate tailings landforms with native plant communities.Read moreRead less

Summary
Mapping the water-energy nexus: new knowledge for resources security. This project plans to systematically evaluate energy impacts of urban water security across three interconnected systems: the direct consequences of water supply; the indirect influence of water use in industry and homes; and the remote implications of water security on supply chains. The project intends to use a new, high-resolution, open-access, multi-regional, input-output model of the Australian economy and its resources u ....Mapping the water-energy nexus: new knowledge for resources security. This project plans to systematically evaluate energy impacts of urban water security across three interconnected systems: the direct consequences of water supply; the indirect influence of water use in industry and homes; and the remote implications of water security on supply chains. The project intends to use a new, high-resolution, open-access, multi-regional, input-output model of the Australian economy and its resources use: the Industrial Ecology Virtual Laboratory. It expects to help address escalating energy demands and costs for urban water by identifying alternative and optimal pathways for addressing the energy impacts of water supply.Read moreRead less
