“…Similarly, the growth of 6 living macroalgae species, i.e., Ulva lactuca, Ulva intestinalis, Fucus spiralis, Fucus vesiculosus, Osmundea pinnatifida and Gracilaria sp. in laboratory-prepared seawater solution containing REEs (Y, La, Ce, praseodymium (Pr), neodymium (Nd), Eu, Gd, Tb, dysprosium (Dy)) has been studied ( Pinto et al, 2021 ). However, until now, only a few studies have been conducted to evaluate the growth and accumulation of REEs present in waste luminophores.…”

“…Regarding WEE (e.g., CFL lights) as secondary source of REEs, only a few studies have demonstrated the use of microalgae as potential REE accumulators/sorbents or removers ( Čížková et al, 2021 ). However, several studies have been conducted that demonstrate the growth of green and red algae in the presence of a single REE, or waste containing a mixture of REEs ( Čížková et al, 2021 ; Pinto et al, 2021 ). The growth of green algae Chlamydomonas reinhardtii , Chlorella sp.…”

“…However, the underlying mechanisms controlling the effect of phytohormones on bioremediation are elusive ( Piotrowska-Niczyporuk et al, 2012 , 2018 ). Unlike HM bioremediation, fewer studies have been conducted to understand REE bio-removal/bioaccumulation ( Pinto et al, 2020 ; Čížková et al, 2021 ; Pinto et al, 2021 ). Literature describing the use of chemical agents commonly employed in bioremediation, or phytohormones that affect the biosorption/bio-removal of REEs are also scarce.…”

In recent decades, a shift has been seen in the use of light-emitting diodes over incandescent lights and compact fluorescent lamps (CFL), which eventually led to an increase in wastes of electrical equipment (WEE), especially fluorescent lamps (FLs) and CFL light bulbs. These widely used CFL lights, and their wastes are good sources of rare earth elements (REEs), which are desirable in almost every modern technology. Increased demand for REEs and their irregular supply have exerted pressure on us to seek alternative sources that may fulfill this demand in an eco-friendly manner. Bio-removal of wastes containing REEs, and their recycling may be a solution to this problem and could balance environmental and economic benefits. To address this problem, the current study focuses on the use of the extremophilic red alga, Galdieria sulphuraria, for bioaccumulation/removal of REEs from hazardous industrial wastes of CFL bulbs and the physiological response of a synchronized culture of G. sulphuraria. A CFL acid extract significantly affected growth, photosynthetic pigments, quantum yield, and cell cycle progression of this alga. A synchronous culture was able to efficiently accumulate REEs from a CFL acid extract and efficiency was increased by including two phytohormones, i.e., 6-Benzylaminopurine (BAP - Cytokinin family) and 1-Naphthaleneacetic acid (NAA - Auxin family).

“…These characteristics make seaweeds compelling organisms for bioremediation and CRM recycling. Recently, Pinto et al (2020;2021) observed that the green seaweed Ulva lactuca has a high capacity to absorb light rare earth elements (>60%), such as Y, La, Ce, Praseodymium (Pr), Nd, Eu, Gadolinium (Gd), Terbium (Tb) and Dysprosium (Dy); Gracilaria gracilis can absorb La, Ce, Pr, Gd and Nd; and Fucus vesiculosus, La, Ce and Eu [18,29]. Another study focusing in Ulva and Gracilaria species also showed that these seaweeds have a high ability to capture Nd from ecosystems [21].…”

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.

“…Com base neste trabalho, o grupo de investigação da UA tem vindo a desenvolver vários outros estudos dando ênfase ao uso das macroalgas, confirmando a sua capacidade e apetência para a remoção dos poluentes tóxicos convencionais, como o Cd, Cr, Cu, Hg, Ni e P [22,23], mas igualmente para a remoção de REE [24,25].…”
