The Composting of Water Hyacinth: A Life Cycle Assessment Perspective
Serafini, Lais Fabiana; Arrobas, Margarida; Rodrigues, Manuel Ângelo; Feliciano, Manuel; Miguens, Filomena; Oliveira, Verónica; Santos, DanielaWater hyacinth is an invasive species that causes eutrophication in lentic waters. While mechanical removal is effective, it generates hazardous waste with biological contamination risk. Composting is a safe waste treatment option, inhibiting seeds and yielding agriculturally suitable compost. Life cycle assessment evaluated the environmental impacts of six composting piles using eight different by-products (po...
Life cycle approach as a tool for assessing municipal biowaste treatment units:...
Serafini, Lais Fabiana; Praça, Paulo; González-Andrés, Fernando; Gonçalves, ArturBiowaste is an increasingly relevant environmental issue worldwide, causing significant environmental, economic and social impacts. Effective strategies are crucial to mitigate impacts, maximising biowaste’s valorisation. This article presents a systematic literature review on using life cycle assessment (LCA) to evaluate municipal biowaste treatment facilities. The primary objective was to analyse how LCA is a...
Use of data from the advanced spaceborne thermal emission and reflection radiom...
Almeida, Cátia Rodrigues de; Alírio, João; Gonçalves, Artur; Teodoro, Ana Cláudia M.The Urban Heat Island (UHI) effect refers to the temperature difference between urban and surrounding rural areas, with higher temperatures in urban areas, especially after sunset. The Surface Urban Heat Island (SUHI), a proxy for UHI, can be evaluated using Remote Sensing (RS) data by calculating the Land Surface Temperature (LST). Bragança (Portugal) has an in situ network, with 23 sensors installed in 2011, ...
Modelo para la integración de las obras de ingeniería en el entorno urbano: int...
Rosado-García, María Jesús; Gonçalves, ArturEl reto actual de las ciudades se centra en la sostenibilidad y ello va a exigir un gran pacto a que permita encontrar sinergias positivas entre los territorios. La reciprocidad entre los entornos urbanos y la sociedad hace que ésta última ha de ser capaz de entender lo que la ciudad necesita y que los ciudadanos identifiquen el escenario de ciudad que desean. En lo que refiere a la configuración del espacio pú...
Estudo prospectivo sobre economia circular na ótica da academia portuguesa
Bozz, Deborah; Gonçalves, Artur; Santos Junior, Elias Lira dosA economia circular surge com a necessidade da sociedade de gerir a produção e o consumo de forma mais sustentável. O presente trabalho tem como objetivo apresentar um panorama da pesquisa portuguesa sobre economia circular, a fim de verificar o estágio atual da produção científica nacional. A pesquisa foi realizada na base de dados Repositório Científico de Acesso Aberto de Portugal (RCAAP), foram encontrados ...

Analysis of the urban heat island in Bragança, Portugal, using MODIS data (2003...
Almeida, Cátia Rodrigues de; Alirio, João; Gonçalves, Artur; Teodoro, Ana CláudiaUrban Heat Island (UHI) is an effect that corroborates to the increase of temperature in urban settlements when compared to the surrounding vegetated areas, especially after sunset. This research aimed to understand the Surface Urban Heat Island (SUHI), a sub-classification correlated to the UHI effect, in the city of Bragança (Portugal), at 23 points classified in different Local Climate Zone (LCZ), between 20...
Remote sensing analysis of the surface urban heat island effect in Vitoria-Gast...
Errea, Cristina Laurenti; Almeida, Cátia Rodrigues de; Gonçalves, Artur; Teodoro, Ana CláudiaVitoria-Gasteiz has taken several urban greening actions such as the introduction of a ring of parks that connect the city's surroundings, a sustainable mobility plan, and urban green structure strategies. Previous studies establish a connection to the importance of greening to mitigate the surface urban heat island (SUHI) and evaluate the effectiveness of these measures on urban climate. In this study, land su...
Systematic review and meta-analysis on the use of LCA to assess the environment...
Serafini, Laís Fabiana; Feliciano, Manuel; Rodrigues, M.A.; Gonçalves, ArturFollowing the industrial revolution, major economic and populational growth took place, and, therefore, solid waste generation increased exponentially. Nowadays, waste management still generates major impacts because the current wide offer of waste management strategies includes many solutions that produce suboptimal results, such as landfill or waste incineration. From a circular economy perspective, compostin...
Time-series analyses of land surface temperature changes with Google Earth Engi...
Almeida, Cátia Rodrigues de; Garcia, Nuno; Campos, João C.; Alirio, João; Arenas-Castro, Salvador; Gonçalves, Artur; Sillero, NeftaliStudying changes in temperature is fundamental for understanding its interactions with the environment and biodiversity. However, studies in mountainous areas are few, due to their complex formation and the difficulty of obtaining local data. We analysed changes in temperature over time in Montesinho Natural Park (MNP) (Braganca, Portugal), an important conservation area due to its high level of biodiversity. S...
