Título: Indicadores para gestão de resíduos sólidos em feiras multissetoriais Autor(es): Zotti, Pedro Gabriel Maschio Primeiro Orientador: Locatelli, Débora Regina Schneider Abstract/Resumen: Multi-sector fairs are temporary in nature and have a high flow of people, resulting in the significant generation of waste in short periods of time. Sustainability indicators are effective tools for monitoring and evaluating solid waste management. Therefore, this research aims to develop and study specific sustainability indicators for solid waste management in multi-sector fairs. The specific objectives are: to highlight the existing gap regarding the existence and use of sustainability indicators directly aimed at fairs and events; to establish a set of sustainability indicators for solid waste management in multi-sector fairs; to apply these indicators to fairs held in municipalities associated with the Association of Municipalities of Alto Uruguai (AMAU); and to use the data obtained from the indicators to develop guidelines that assist in the waste management process of the fairs studied. The methodology consisted of bibliographic studies using databases included in the CAPES Periodicals Portal and the application of a set of indicators in two multi-sector fairs: the XV Spring Festival held in Erval Grande and Expoara held in Aratiba. Data collection was carried out through observation, gravimetric composition, and collection of documentary data. The result was a set of 12 sustainability indicators applicable to multi-sector fairs, capable of identifying inconsistencies and failures in solid waste management systems, as well as assisting in the decision-making process through guidelines, helping managers and those responsible to make decisions for the implementation of more sustainable events.

Título: Production of Biocomposites derived from fermented Chlorella sp. with Wickerhamomyces sp. UFFS-CE-3.1.2 Autor(es): Longo, Vitória Dassoler Primeiro Orientador: Treichel, Helen Abstract/Resumen: The transition toward a circular economy and the pursuit of environmental sustainability are driving humanity to develop alternative technologies for producing various bioproducts. In this context, fermentation processes mediated by microorganisms have gained prominence. Although yeasts are well recognized for their ability to produce alcohols, they are also capable of generating a wide range of value-added byproducts. In parallel, microalgae emerge as an advantageous non-conventional feedstock, as their cultivation does not require arable land, thereby avoiding competition with food production. Addressing this demand, the present study aimed to produce biocompounds through submerged fermentation using biomass from the microalga Chlorella sp. Enzymatic hydrolysis was optimized through a Central Composite Rotational Design (CCRD) 2², with algal biomass and enzyme mass as independent variables. This step was followed by fermentation with the yeast Wickerhamomyces sp. UFFS-CE-3.1.2. The enzyme alpha amylase employed is of commercial origin, commonly used in the brewing industry, characterized by its easy accessibility and lower environmental impact compared to chemical hydrolysis methods. The results demonstrated that the combination of microalgal biomass with enzymatic preparation led to the production of several compounds of interest, such as glycerol and acetic acid. These products have broad industrial applications and market demand, supporting the potential of yeast–microalgae synergy for the sustainable production of high-value biocompounds.

Título: Bioremediation as a strategy for recovering water contaminated by floods associated with climate change: emphasis on removing emerging pollutants Autor(es): Raimundi, Mayana Cardoso Primeiro Orientador: Treichel, Helen Abstract/Resumen: Climate change has increased the frequency of floods, dispersing emerging contaminants into water bodies and posing a growing challenge to environmental quality. This study presents a literature review on bioremediation as a sustainable strategy for treating and recovering waters contaminated by extreme hydrological events. Studies published between 2020 and 2025 were analyzed, focusing on microorganisms and technologies applied to the degradation of pollutants, including pharmaceuticals, pesticides, plastics, and heavy metals. Bacterial, fungal, and algal species, as well as mixed microbial consortia, showed high removal rates, often exceeding 90%. Innovative technologies, including enzymatic immobilization, membrane bioreactors, and other integrated systems, further enhanced process efficiency. The results emphasize that bioremediation, combined with advances in environmental biotechnology, represents an effective, economical, and ecologically safe alternative for mitigating water pollution in scenarios intensified by climate change.

Título: Aplicação dos processos hibridos de eletrocoagulação e ozonização na degradação dos fármacos presentes em efluente sanitário Autor(es): Flores, Gabriela Cristina Perusin Primeiro Orientador: Pasqualli, Gean Delise Leal Abstract/Resumen: The presence of emerging contaminants, particularly pharmaceuticals such as triclosan and ciprofloxacin, in domestic wastewater has become a growing environmental concern due to their low biodegradability and potential ecological toxicity. This study evaluated the efficiency of electrocoagulation and ozonation, applied sequentially, for the removal of these compounds from sanitary effluent collected at the Wastewater Treatment Plant of UFFS – Erechim Campus. The effluent was initially characterized, followed by kinetic assays to determine the optimal treatment time and the most suitable voltage for electrocoagulation. The results showed a removal of 15% of triclosan and 51.8% of ciprofloxacin after electrocoagulation, while the ozonation treatment increased triclosan removal to 37.3%. High efficiencies were obtained for the physicochemical parameters with the sequential process of electrocoagulation followed by ozonation, resulting in final removals of turbidity (95.9%), color (83.9%), and 23.3% of total organic carbon. These findings highlight the potential of combining electrocoagulation and ozonation as an effective strategy for treating recalcitrant pharmaceuticals and improving effluent quality, reinforcing the applicability of advanced oxidation processes as complementary technologies to conventional wastewater treatment.
