“…The ability of algae, bacteria, and yeasts to use diverse products for growing (especially agriculture and aquaculture wastes or even flue gases in the case of algae) makes them very attractive in the context of the circular economy [ 22 , 23 , 24 , 25 , 26 , 27 , 28 , 29 , 30 , 31 ].…”

Carotenoids are a large group of health-promoting compounds used in many industrial sectors, such as foods, feeds, pharmaceuticals, cosmetics, nutraceuticals, and colorants. Considering the global population growth and environmental challenges, it is essential to find new sustainable sources of carotenoids beyond those obtained from agriculture. This review focuses on the potential use of marine archaea, bacteria, algae, and yeast as biological factories of carotenoids. A wide variety of carotenoids, including novel ones, were identified in these organisms. The role of carotenoids in marine organisms and their potential health-promoting actions have also been discussed. Marine organisms have a great capacity to synthesize a wide variety of carotenoids, which can be obtained in a renewable manner without depleting natural resources. Thus, it is concluded that they represent a key sustainable source of carotenoids that could help Europe achieve its Green Deal and Recovery Plan. Additionally, the lack of standards, clinical studies, and toxicity analysis reduces the use of marine organisms as sources of traditional and novel carotenoids. Therefore, further research on the processing of marine organisms, the biosynthetic pathways, extraction procedures, and examination of their content is needed to increase carotenoid productivity, document their safety, and decrease costs for their industrial implementation.

“…Conducting an LCA investigation facilitates the identification of critical areas of concern within an algae production chain, pinpointing where issues may arise [34,35]. Adopting life cycle assessment (LCA) methodology within the algae industry has witnessed a growing prevalence, particularly in assessing products and services within the food and energy sector [14,[36][37][38][39][40][41][42]. The LCA tool enables precise quantifica-tion of environmental emissions, pinpointing vital aspects, contrasting processes, and appraising the potential for adopting innovative production methods in contrast to current alternatives [10].…”

This study evaluated the environmental impacts of producing 1 kg of biomass for animal feed grown in inland fisheries effluents as a culture medium using the ReCiPe method. Four scenarios with two downstream alternatives were modeled using the life cycle assessment method: Algal Life Feed (ALF), Algal Life Feed with Recycled nutrients (ALF+Rn), Pelletized Biomass (PB), and Pelletized Biomass with Recycled nutrients (PB+Rn). The findings reveal a substantial reduction in environmental impacts when wastewater is employed as a water source and nutrient reservoir. However, the eutrophication and toxicity-related categories reported the highest normalized impacts. ALF+Rn emerges as the most promising scenario due to its reduced energy consumption, highlighting the potential for further improvement through alternative energy sources in upstream and downstream processes. Therefore, liquid waste from fish production is a unique opportunity to implement strategies to reduce the emission of nutrients and pollutants by producing microalgae rich in various high-value-added metabolites.

“…For instance, Mohammed et al [13] found that converting phosphogypsum -an industrial waste generated by phosphoric acid production-to sodium sulphate and ammonium sulphate leads to negative environmental impacts (global warming potential, eutrophication potential and water use). Moreover, Rodríguez et al [14] evaluated a symbiotic system linking a fishmeal facility with a microalgae plant, where flue gas replaces pure CO 2 . The results showed that a net reduction of greenhouse gas (GHG) emissions was achievable only when low-carbon electricity was consumed (less than 9% of fossil fuels).…”
