Resveratrol-based biorefinery models for favoring its inclusion along the marke...
Arias, Ana; Costa, Carlos E.; Moreira, Maria Teresa; Feijoo, Gumersindo; Domingues, LucíliaResveratrol, a natural organic polyhydroxyphenolic compound, has gained significant attention in the last years given its potential health benefits, including antioxidant, anti-cancer, and anti-inflammatory properties. It can be directly extracted from plants, vegetables, and related products and waste resources, but also chemically/enzymatically/microbially synthesized. However, certain process strategies have...
Process modeling, environmental and economic sustainability of the valorization...
Arias, Ana; Costa, Carlos E.; Feijoo, Gumersindo; Moreira, Maria Teresa; Domingues, LucíliaBiomass is one of the renewable resources with the greatest potential, not only because of the possibility of energy recovery but also because of its content in components of interest. In this context, the regions of Galicia and Portugal have large areas of land dedicated to forestry, agriculture and livestock, and the large amount of waste generated represents a cost for the producer. The importance of these f...
Environmental and techno-economic assessment on the valorization of vine-side s...
Arias, Ana; Costa, Carlos E.; Moreira, Maria Teresa; Feijoo, Gumersindo; Domingues, LucíliaOne of the most promising alternatives to face the environmental deterioration and handling of waste is the development of biotechnological processes. In this context, the winemaking process of red grapes gives rise to waste streams whose properties are suitable for the biotechnological production of high-value-added products, such as resveratrol, a polyphenol with functional properties. In this research articl...
Evaluating the carbon footprint of a Spanish city through environmentally exten...
Rama, Manuel; Entrena-Barbero, Eduardo; Dias, Ana Cláudia; Moreira, María Teresa; Feijoo, Gumersindo; González-García, SaraCurrently, most of the greenhouse gas (GHG) emissions are attributed to cities, as they are the global centers of business, residential and cultural activity, cities are expected to play a leading role in proposing climate change mitigation actions. To do so, it is important to have tools that allow the carbon footprint of cities to be assessed as accurately as possible. This study aims to quantify the carbon f...
Life cycle assessment of fish and seafood processed products - a review of meth...
Ruiz-Salmón, Israel; Laso, Jara; Margallo, María; Villanueva-Rey, Pedro; Rodríguez, Eduardo; Quinteiro, Paula; Dias, Ana Cláudia; Almeida, CheilaLife cycle assessment (LCA) has been widely applied in many different sectors, but the marine products and seafood segment have received relatively little attention in the past. In recent decades, global fish production experienced sustained growth and peaked at about 179 million tonnes in 2018. Consequently, increased interest in the environmental implications of fishery products along the supply chain, namely...
Addressing challenges and opportunities of the European seafood sector under a ...
Ruiz-Salmón, Israel; Margallo, María; Laso, Jara; Villanueva-Rey, Pedro; Mariño, Dolores; Quinteiro, Paula; Dias, Ana Cláudia; Nunes, Maria LeonorThe European seafood and aquaculture sectors are facing important challenges in terms of environmental threats (climate change, marine debris, resources depletion), social development (worker rights, consumer's awareness) or economic growth (market and nonmarket goods and services, global competitiveness). These issues are forcing all stakeholders, from policy-makers to citizens and industries, to move to more ...
Efficiency assessment of diets in the Spanish regions: a multi-criteria cross-c...
Esteve-Llorens, Xavier; Martín-Gamboa, Mario; Iribarren, Diego; Moreira, Maria Teresa; Feijoo, Gumersindo; González-García, SaraFood systems are one of the main drivers of the global greenhouse gases emissions from anthropogenic sources, which could be aggravated by the projected increase in world population. Hence, the adoption of sustainable diets that guarantee good and accessible nutrition and a low environmental impact is an increasingly important need. This goal is, by nature, a multi-dimensional and multi-criteria challenge that ...
Turning waste management into a carbon neutral activity: practical demonstratio...
Fernández Braña, Álvaro; Feijoo, Gumersindo; Ferreira, CéliaA Life Cycle Assessment (LCA) with focus on carbon footprint, followed by Life Cycle Costing (LCC) of municipal solid waste (MSW) management were conducted in a residential area of a medium-sized European city of 80,000 inhabitants. The initial results showed high environmental impacts and lack of economic sustainability, due to the high amounts of waste landfilled, the low extent of separate collection, low pe...
Looking beyond the banning of lightweight bags: analysing the role of plastic (...
Fernández Braña, Álvaro; Feijoo, Gumersindo; Ferreira, CéliaThe purpose of this work is to assess the environmental impacts of the collection of mixed municipal solid waste (MSW) in a selected neighbourhood of the Portuguese city of Aveiro. To this purpose, the main elements necessary for the collection process (carrier bags, dustbins, street containers and vehicles) were analysed applying the life cycle assessment methodology, making use of locally gathered data. The m...
Integrating urban metabolism, material flow analysis and life cycle assessment ...
García-Guaita, Fernando; González-García, Sara; Villanueva-Rey, Pedro; Moreira, María Teresa; Feijoo, GumersindoAchieving urban sustainability has become imperative. The combination of Material Flow Analysis (MFA) and Life Cycle Assessment (LCA) could be considered an attractive method to assess the sustainability of a city’s metabolism. However, the need for exhaustive data makes this method time-consuming and uncertain. This study carries out a simplified UM-MFA-LCA analysis of the city of Santiago de Compostela (Spain...
