Rare Earth Elements (REEs) are indispensable in contemporary technologies, influencing various aspects of our daily lives and environmental solutions. The escalating demand for REEs has led to increased exploitation, resulting in the generation of diverse REE-bearing solid and liquid wastes. Recognizing the potential of these wastes as secondary sources of REEs, researchers are exploring microbial solutions for their recovery. This mini review provides insights into the utilization of microorganisms, with a particular focus on microalgae, for recovering REEs from sources such as ores, electronic waste, and industrial effluents. The review outlines the principles and distinctions of bioleaching, biosorption, and bioaccumulation, offering a comparative analysis of their potential and limitations. Specific examples of microorganisms demonstrating efficacy in REE recovery are highlighted, accompanied by successful methods, including advanced techniques for enhancing microbial strains to achieve higher REE recovery. Moreover, the review explores the environmental implications of bio-recovery, discussing the potential of these methods to mitigate REE pollution. By emphasizing microalgae as promising biotechnological candidates for REE recovery, this mini review not only presents current advances but also illuminates prospects in sustainable REE resource management and environmental remediation.

“…Some investigations conducted in real matrices use living algae, which is beyond the scope of this work. [126][127][128][129][130] When non-living algae are applied to effluents, it is common to perform algae surface modifications, spiking wastewater with metals or using high algae-to-metal ratios. 118,[131][132][133][134][135][136] Onyancha et al 118 reported the use of pre-treated Spirogyra condensate as a sorbent for Cr 3+ in treated tannery effluent (Cr 3+ concentration of 8.26 ± 0.06 mg L −1 ) and tannery sludge (Cr 3+ concentration of 3356.70 ± 0.25 mg L −1 ).…”

“…An increase in sorption efficiency of about 10% was observed for La and Ce after modification (initial concentration of 100 mg L −1 ), showing that the pre-treatment of the biomass promoted REE sorption. In another case, Sun et al ( 2022 ) provided a detailed description of the sorption process when immobilizing the extremophile microalga Galdieria sulphuraria in calcium alginate to remove three REE (Y, La, Sm). The authors noted a significant release of Ca 2+ during the sorption process, leading them to hypothesise that sorption occurs in two distinct phases: initial adsorption based on the affinity of REE towards the available functional groups, and a second phase based on ion exchange in which REE are exchanged with the Ca 2+ from the calcium alginate.…”

Efficient and sustainable secondary sourcing of Rare-Earth Elements (REE) is essential to counter supply bottlenecks and the impacts associated with primary mining. Recycled electronic waste (E-waste) is considered a promising REE source and hydrometallurgical methods followed by chemical separation techniques (usually solvent extraction) have been successfully applied to these wastes with high REE yields. However, the generation of acidic and organic waste streams is considered unsustainable and has led to the search for “greener” approaches. Sorption-based technologies using biomass such as bacteria, fungi and algae have been developed to sustainably recover REE from e-waste. Algae sorbents in particular have experienced growing research interest in recent years. Despite its high potential, sorption efficiency is strongly influenced by sorbent-specific parameters such as biomass type and state (fresh/dried, pre-treatment, functionalization) as well as solution parameters such as pH, REE concentration, and matrix complexity (ionic strength and competing ions). This review highlights differences in experimental conditions among published algal-based REE sorption studies and their impact on sorption efficiency. Since research into algal sorbents for REE recovery from real wastes is still in its infancy, aspects such as the economic viability of a realistic application are still unexplored. However, it has been proposed to integrate REE recovery into an algal biorefinery concept to increase the economics of the process (by providing a range of additional products), but also in the prospect of achieving carbon neutrality (as large-scale algae cultivation can act as a CO2 sink).
