“…The biomass screening included different macroalgae, microalgae and cyanobacteria to facilitate the simultaneous comparison of the metal sorption capacity of different biomass. This is usually done by comparing works conducted under different experimental conditions [20] and limited biomass diversity, [19,39] which hinders the comparison of the sorption capacity of macroalgae, microalgae and cyanobacteria. [19,20,39,40] A comprehensive screening was performed in multi-elemental metal solutions since metal recovery often involves complex matrices.…”

“…The transition from traditional to greener energy sources (e.g., wind turbines) and countless high-tech devices rely on rare-earth elements (REE), whose mining and processing are environmentally unfriendly [1]. Increasing REE concentrations in water bodies due to ineffective treatment in wastewater treatment plants and leaching from untreated e-waste have been reported worldwide [2].…”

“…Ulva sp. (live) Nd >90% [21] Due to their high value for new technology development and to their high toxicity for humans and the environment, several strategies have been developed to recover REEs from different polluted scenarios. These include costly techniques such as reverse osmosis, ion-exchange, solvent extraction, and electrochemical separation, which produce other toxic secondary products in the process that need to be addressed, thus increasing the processing costs substantially.…”

Resulting from the growing human population and the long dependency on fossil-based energies, the planet is facing a critical rise in global temperature, which is affecting all ecosystem networks. With a growing consciousness this issue, the EU has defined several strategies towards environment sustainability, where biodiversity restoration and preservation, pollution reduction, circular economy, and energetic transition are paramount issues. To achieve the ambitious goal of becoming climate-neutral by 2050, it is vital to mitigate the environmental footprint of the energetic transition, namely heavy metal pollution resulting from mining and processing of raw materials and from electronic waste disposal. Additionally, it is vital to find alternative materials to enhance the efficiency of energy storage devices. This review addresses the environmental challenges associated with energetic transition, with particular emphasis on the emergence of new alternative materials for the development of cleaner energy technologies and on the environmental impacts of mitigation strategies. We compile the most recent advances on natural sources, particularly seaweed, with regard to their use in metal recycling, bioremediation, and as valuable biomass to produce biochar for electrochemical applications.
