1. Innovative solutions for valorization of desalination brineAna Rotter, Baruch Rinkevich, Irem Deniz, Maggie M. Reddy, Mariana Girão, Maria F. Carvalho, Nina Gunde-Cimerman, Cene Gostinčar, Mercedes Cueto, Ernesta Grigalionyte-Bembič, 2025, izvirni znanstveni članek Povzetek: Desalination is becoming increasingly important to meet the growing demand for freshwater. However, a major drawback of this technology is the production of hypersaline brine. This by-product contains salts and contaminants that have been removed during the desalination process, including antiscalants, cleaning agents, heavy metals, and organic compounds. Instead of disposing of this brine and causing environmental harm, new strategies should be developed to transform brine from a burden into an opportunity with environmental and economic benefits. Brine can harbor halotolerant and halophilic microorganisms, making it a valuable resource for studying microbial diversity, adaptations and exploring untapped biotechnological opportunities in pharmaceutical, industrial, and ecological fields. We propose two strategies of innovation: (i) using brine to cultivate micro- and macro-organisms, both of which can create circular economy models tailored to global and local needs. (ii) In addition, the amount of brine generated by desalination plants can be reduced by integrating or coupling them with biodesalination modules. These modules would harness halotolerant and halophilic organisms to retain and assimilate salts, reducing the environmental impact of desalination.

2. From the sea to aquafeed : a perspective overviewOrhan Tufan Eroldogan, Brett Glencross, Lucie Novoveská, Susana P. Gaudêncio, Buki Rinkevich, Giovanna Cristina Varese, Maria F. Carvalho, Deniz Tasdemir, Ivo Safarik, Soren Laurentius Nielsen, Céline Rebours, Lada Lukić-Bilela, Johan Robbens, Evita Strode, Berat Z. Haznedaroglu, Marlen I. Vasquez, Ivana Čabarkapa, Slađana Rakita, Katja Klun, Ana Rotter, 2023, pregledni znanstveni članek Povzetek: Aquaculture has been one of the fastest-growing food production systems sectors for over three decades. With its growth, the demand for alternative, cheaper and high-quality feed ingredients is also increasing. Innovation investments on providing new functional feed alternatives have yielded several viable alternative raw materials. Considering all the current feed ingredients, their circular adaption in the aquafeed manufacturing industry is clearly of the utmost importance to achieve sustainable aquaculture in the near future. The use of terrestrial plant materials and animal by-products predominantly used in aquafeed ingredients puts a heavily reliance on terrestrial agroecosystems, which also has its own sustainability concerns. Therefore, the aquafeed industry needs to progress with functional and sustainable alternative raw materials for feed that must be more resilient and consistent, considering a circular perspective. In this review, we assess the current trends in using various marine organisms, ranging from microorganisms (including fungi, thraustochytrids, microalgae and bacteria) to macroalgae and macroinvertebrates as viable biological feed resources. This review focuses on the trend of circular use of resources and the development of new value chains. In this, we present a perspective of promoting novel circular economy value chains that promote the re-use of biological resources as valuable feed ingredients. Thus, we highlight some potentially important marine-derived resources that deserve further investigations for improving or addressing circular aquaculture.

3. A new network for the advancement of marine biotechnology in Europe and beyondAna Rotter, Ariola Bacu, Michèle Barbier, Francesco Bertoni, Atle M. Bones, M. Leonor Cancela, Jens Carlsson, Maria F. Carvalho, Marta Cegłowska, Meltem Conk Dalay, Jerica Sabotič, 2020, izvirni znanstveni članek Povzetek: Marine organisms produce a vast diversity of metabolites with biological activities useful for humans, e.g., cytotoxic, antioxidant, anti-microbial, insecticidal, herbicidal, anticancer, pro-osteogenic and pro-regenerative, analgesic, anti-inflammatory, anti-coagulant, cholesterol-lowering, nutritional, photoprotective, horticultural or other beneficial properties. These metabolites could help satisfy the increasing demand for alternative sources of nutraceuticals, pharmaceuticals, cosmeceuticals, food, feed, and novel bio-based products. In addition, marine biomass itself can serve as the source material for the production of various bulk commodities (e.g., biofuels, bioplastics, biomaterials). The sustainable exploitation of marine bio-resources and the development of biomolecules and polymers are also known as the growing field of marine biotechnology. Up to now, over 35,000 natural products have been characterized from marine organisms, but many more are yet to be uncovered, as the vast diversity of biota in the marine systems remains largely unexplored. Since marine biotechnology is still in its infancy, there is a need to create effective, operational, inclusive, sustainable, transnational and transdisciplinary networks with a serious and ambitious commitment for knowledge transfer, training provision, dissemination of best practices and identification of the emerging technological trends through science communication activities. A collaborative (net)work is today compelling to provide innovative solutions and products that can be commercialized to contribute to the circular bioeconomy. This perspective article highlights the importance of establishing such collaborative frameworks using the example of Ocean4Biotech, an Action within the European Cooperation in Science and Technology (COST) that connects all and any stakeholders with an interest in marine biotechnology in Europe and beyond.

4. Site-specific dataset of mining and metallurgical residues for resource managementCarlo Cormio, Marta Fernández-Alonso, Peter Cleall, Soraya Heuss-Aßbichler, Daniela Guglietta, Danielle Sinnett, Katalin Szabó, Gorazd Žibret, Maria Teresa Carvalho, Ulrich Kral, Tim T. Werner, Bruno Lemiere, 2024, drugi znanstveni članki Povzetek: This geospatial dataset provides a compilation of findings from an evidence-based review of site-specific resource assessments of mining and metallurgical residues. Information pertaining to location, target material, geological knowledge, extractability, resource classification and stakeholder perspectives was collected from publicly available reports, articles, academic theses, and databases. The dataset includes 44 relevant data attributes from 64 mining and metallurgical sites in 27 countries. Resource classification is available for 38 sites. The dataset can be used by evaluators of recovery projects, authorities that provide permits, as well as by decision makers in support of developing regulatory policies. The dataset facilitates future addition of sites by the research community and can be further used as a starting point to bridge the estimates on recoverable quantities to the United Nations Framework Classification (UNFC). The UNFC is a universally applicable scheme for the sustainable management of all energy, primary and secondary mineral resources. Its use is stimulated by the European Commission and is intended to be adopted by geological surveys to harmonize the data on the availability of primary and secondary raw materials in Europe in future.
