Algae Solutions for Sustainable Mine Closure
Algae-based technologies may deliver sustainable post‑mining futures through mine water treatment, carbon sequestration, rehabilitation, and circular bioeconomy opportunities.
This Stage 1 CRC TiME report evaluates the potential of algae-based technologies to improve environmental outcomes and enable sustainable post‑mining futures. It reviews global and Australian evidence on cultivating micro‑ and macroalgae at mine sites, using mine water to treat acidity, salinity, metals and nutrients while sequestering carbon.
The report outlines how algal biomass can support mine waste stabilisation, dust suppression, soil rehabilitation and revegetation, and generate value‑added products such as bio-fertilisers, bioplastics, pigments, biofuels and animal feed. It assesses cultivation, harvesting and processing technologies, regulatory and community considerations, and engagement with Traditional Owners.
A preliminary business case highlights economic, social and environmental benefits, alongside risks and constraints. The report identifies key research gaps and opportunities to inform a targeted Stage 2 program and pilot-scale demonstrations.
