Algae-based technologies offer various solutions to mitigate the environmental impacts of mining during operations and after closure. Algae sequester CO2 into biomass, allowing possible offsetting of carbon emissions. Algae can also facilitate the removal of various contaminants from mine water, dust suppression, stabilisation of mine waste, and mine-site rehabilitation. The cultivation of algae at mine sites may also provide opportunities for the manufacture of valuable products such as pigments, bioplastics, biofuels, and animal feed. This presents the potential to establish a bio-based economy, creating job opportunities for local communities. The feasibility of cultivating and utilising algae requires a case-by-case evaluation of technical performance, local conditions, regulatory constraints, economic feasibility, and environmental impacts. This study aims to explore the potential of various algae-based technologies designed for cultivating, harvesting, and utilising algae at mine sites for beneficial purposes.
