In this context, the Brazilian National Solid Waste Policy (Law No. 12,305/2010) establishes objectives, principles, instruments, and targets for the efficient management of waste, requiring companies to implement a Solid Waste Management Plan (SWMP). Thus, this study aims to analyze the solid waste management practices of an electric shower manufacturing plant located in the state of Sergipe, Brazil, in order to propose improvements to the existing system. The research was conducted through a literature review on solid waste management, complemented by technical site visits and analysis of internal technical documents. Overall, the results indicated the need to update the management plan, particularly regarding solid waste classification in accordance with NBR 10.004:2024, as well as to implement improvements in the processes of segregation, storage, treatment, and material recovery. These actions contribute to environmental preservation and promote the enhancement of the company’s environmental management practices. 2026-04-24T00:00:00Z https://ri.ufs.br/jspui/handle/riufs/24897 Título: Estudo socioambiental das condições sanitárias da comunidade da Prainha em Aracaju-SE Autor(es): Santana Junior, Hillmarques Abstract: The present study aims to investigate the basic sanitation conditions in the Prainha community, located in the northern zone of Aracaju, Sergipe, through the lens of environmental justice and the application of geotechnologies for territorial analysis. The research is based on the observation that, despite being situated in an urbanized area, Prainha faces a historical neglect by public authorities in providing essential services such as water supply, sewage collection and treatment, solid waste management, and urban drainage. This situation reveals an ongoing process of deterritorialization, degradation of local ecosystems, and disruption of traditional ways of life, reflecting structural patterns of exclusion and social invisibility. The methodology adopted includes document analysis, on-site observation, and the use of geoprocessing technologies to map the environmental and socioeconomic conditions of the community. The data indicate that, despite the high sanitation coverage rates reported for Aracaju, the reality in Prainha starkly contrasts with these official figures, exposing a significant disconnect between the reported statistics and the lived experiences of traditional populations. The lack of adequate sanitation not only compromises public health but also exacerbates sociospatial inequalities and environmental conflicts, as the degradation of local water resources has intensified with the industrialization of the surrounding neighborhood, directly impacting the quality of life for Prainha's residents. The findings suggest that achieving universal access to basic sanitation, as envisioned by the National Basic Sanitation Policy (Laws Nº. 11,445/2007 and Nº. 14,026/2020), remains a distant goal for communities like Prainha, which continue to be marginalized and disproportionately exposed to socio-environmental risks. It is concluded that overcoming this scenario requires not only the expansion of physical infrastructure but also the strengthening of public policies that recognize the territorial and cultural specificities of these populations, promoting socio-environmental justice as a guiding principle for sustainable urban planning. 2026-03-10T00:00:00Z https://ri.ufs.br/jspui/handle/riufs/24871 Título: Qualidade de amostras de água em ambiente universitário : análise físico-química, microbiológica e condições de conservação Autor(es): Jesus, Raisa Rafaela Reis de Abstract: Drinking water is essential to human health, but it is constantly exposed to various contamination risks. In collective and public environments, such as universities, its consumption from drinking fountains requires greater attention to ensure adequate quality and guarantee the water safety of consumers. Thus, the objective of this study was to evaluate the quality of water samples consumed from public drinking fountains located in areas with high pedestrian traffic at the Federal University of Sergipe, São Cristóvão campus. The study was conducted at 14 collection points (13 drinking fountains and the institution's main water reservoir), following standardized sampling, preservation, and analysis protocols. The physicochemical parameters analyzed included apparent color, turbidity, pH, free residual chlorine, and temperature, while the microbiological parameters included total coliforms, Escherichia coli, and heterotrophic bacteria. In addition, a customized visual inspection checklist was used to assess structural conformity, conservation, and hygiene of the drinking fountains. The methodology of this investigation followed a descriptive and exploratory procedure carried out in August 2025. The results showed that some of the drinking fountains presented inadequacies regarding their structure, such as rust spots and unsealed internal reservoir lids, as well as trays with visible biofilms and encrustations. The physicochemical parameters, in general, met the current legislation (Ordinance GM/MS No. 888/2021), although the free residual chlorine mostly showed values below the minimum limit established by law. In terms of microbiology, total coliforms and E. coli were detected in 35.7% of the sampled points, highlighting potential risks of fecal contamination and waterborne diseases for consumers. The analysis of heterotrophic bacteria indicated significant growth in some drinking fountains (14.3%), evidencing conditions favorable to microbial proliferation. No significant pattern was identified that could influence this loss of quality. To provide a better understanding of the study, a weighted composite index was developed, giving greater weight to microbiological parameters (60%), followed by physicochemical (30%) and structural (10%) parameters. This allowed the drinking fountains to be ranked as follows: Pedestrian Entrance/Exit > Did. 4 – 1st floor > Did. 5 – Ground floor = Did. 5 – 1st floor = Did. 6 – Ground floor = Did. 6 – 1st floor > Resun – Ground floor 1 > Resun – Ground floor 2 > Did. 4 – Ground floor > Did. 3 – Ground floor = Bicen – 1st floor. Therefore, it is concluded that, although some samples met potability standards, inadequacies were found that could compromise water safety. Thus, the study reinforces the need for periodic maintenance, continuous monitoring, and preventive measures to ensure the quality of water consumed by the academic community. 2026-03-05T00:00:00Z
