Description

Accelerated tailings remediation with plant and microbial biotechnologies. The Australian alumina industry produces 32 million tonnes of bauxite residue (alumina refining tailings) each year, most of which is stored in perpetuity in landfill-type tailings storage facilities. The high pH, high salinity, lack of plant nutrients, and poor physical properties of bauxite residue are major barriers to safe storage and successful closure of tailings storage facilities. Existing remediation approaches are expensive, slow, and often ineffective. We will deliver new microbial- and plant-driven biotechnologies for rapid, cost-effective remediation of bauxite residue. This will enable safe, sustainable closure of storage facilities, and safeguard the strong contribution of this $15 billion industry to Australia's economy. . Scheme: Linkage Projects.
