The Composting of Water Hyacinth: A Life Cycle Assessment Perspective
Serafini, Laís Fabiana; Arrobas, Margarida; Rodrigues, M.A.; 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 (pot...
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...
Pegada de carbono de sistemas de tratamento de águas residuais urbanas
Serafini, Laís FabianaAs águas residuais urbanas são resultado do uso da água para fins domésticos e industriais, que, se não forem tratadas, se tornam um problema ambiental, contaminando solos e recursos hídricos. Para serem devolvidas ao ambiente, estas águas precisam passar por uma série de etapas de tratamento. As Estações de Tratamento de Águas Residuais (ETARs) são responsáveis pela diminuição do potencial poluidor dessas água...
Experimental study of the effect of temperature on the drying process and volum...
Domenico, Camila Nicola Boeri Di; Serafini, Laís Fabiana; Bavaresco, MaurícioThis study aimed to determine the effect of air temperature on the drying kinetics and volume shrinkage of oat grains. Grains with an initial moisture content of 17% (db) were selected and dried in a forced air circulation oven under three temperature conditions: 65, 75 and 85ºC. To ascertain the volume shrinkage, the grains were dried in trays and then placed in a graduated cylinder. Volume reduction of the gr...
