(INSTITUTO FEDERAL DE ALAGOAS - Ifal, 2025-01-28) Amorim, Paloma Sena; Melo, Ingrid Sofia Vieira de; http://lattes.cnpq.br/4727408608738222; Calheiros, Altanys Silva; https://orcid.org/0000-0001-5985-6602; http://lattes.cnpq.br/9353777923030637; Melo, Joabe Gomes de; http://lattes.cnpq.br/5180399418500159; Silva, Jose Pedro da; http://lattes.cnpq.br/1491552623899332
Non-Conventional Edible Plants (PANC) are edible plants that are not commonly part of the daily diet for most of the population but have high nutritional potential and are integral to the cultural traditions of various communities. This study analyzed the feasibility of incorporating PANC into the school meals of Marechal Deodoro (AL) and developed educational materials to disseminate the findings. The research adopted a descriptive approach, combining quantitative and qualitative methods, including bibliographic research, field research, and case studies. Data were analyzed using electronic spreadsheets and action research, allowing for the integration of analysis and practical application. The results showed that 65% of participants were unfamiliar with the term "PANC," yet 54% already consumed parts of these plants, demonstrating practical knowledge despite lacking familiarity with the terminology. All participants expressed interest in cultivating PANC, and 100% were willing to expand their production. Additionally, 83% reported learning about PANC through popular wisdom, highlighting the importance of traditional knowledge. Based on these findings, an educational material featuring recipes was developed to encourage the introduction of PANC into school meals, promoting nutritional awareness and strengthening local food practices.
Análise da percepção de mulheres em situação de vulnerabilidade em relação ao consumo ecossustentável de produtos de higiene menstrual
(Instituto Federal de Educação Ciência e Tecnologia de Alagoas, 2024-01-30) Silva, Mércia Dark Bastos da; Cunha, Mônica Ximenes Carneiro da; http://lattes.cnpq.br/1775024859845111; Marques, Sheyla Karolina Justino; http://lattes.cnpq.br/3917387578549073; Gaia, Rossana Viana; http://lattes.cnpq.br/4018992389689693
This study focused on assessing the perception of women in situations of social vulnerability in relation to the eco-sustainable consumption of menstrual hygiene items, with special attention to the environmental impacts associated with the improper disposal of these products, as well as their composition and production process. The methodological path comprised four stages: (1) Systematic Literature Review; (2) Case study, incorporating interviews and focus group; (3) Content Analysis; and (4) Production of Technical and Technological Products, including Manuals for the use and production of reusable fabric pads, Didactic Manual of guidelines for a more sustainable and healthy menstrual cycle, Didactic Material of guidelines for a more sustainable and healthy menstrual cycle, and Social Technology – Reusable Fabric Pads. The results show that, for women in vulnerable situations, environmental perception is not one of the main factors influencing the adoption of reusable items. The lack of information, together with the limited availability of these products and economic conditions, emerged as determinants in this transition process. Thus, the need to democratize information is highlighted, promoting the autonomy of menstruating people and facilitating more accurate and ecologically conscious choices. The creation of educational materials, such as manuals and teaching resources, represents a practical contribution to empowering women, enabling informed and conscious choices regarding menstrual hygiene. These resources seek to disseminate information about the benefits of reusable products, encouraging more sustainable and healthy practices.

(2024-10-30) Brandão, Iago Gabriel França; Freitas, Alan John Duarte de; http://lattes.cnpq.br/7222112856028905; Freitas, Johnnatan Duarte de; http://lattes.cnpq.br/4999402869058858; Cabral Júnior, Jório Bezerra; http://lattes.cnpq.br/7439808091974845; Cabral, Mirelle Márcio Santos; http://lattes.cnpq.br/7765541308045861
It is essential to consider the importance of water, a vital resource for life on the planet, when addressing the conservation of its quality. The growing awareness of the health impacts resulting from exposure to a wide range of compounds has led to the strengthening of environmental regulations and policies, such as Ordinance GM/MS No. 888, of May 4, 2021. In recent years, the search for effective ways to reduce environmental impacts has become even greater, since the risk of contamination of water resources is an environmental concern with a major impact on public health. Therefore, the study aims to evaluate and characterize the quality of groundwater, determining some physical-chemical and microbiological parameters. Five wells were selected, where the variables of pH, turbidity, electrical conductivity, color, temperature, alkalinity, total hardness, calcium, magnesium, chlorides, acidity, total coliforms and thermotolerant coliforms were analyzed. Microbiological analyses were performed to assess the presence or absence of total and thermotolerant coliforms. Subsequently, field and laboratory tests were carried out. The results obtained during the tests indicated that the analyzed waters require different treatments, inherent to their specific quality. Well 02 meets all the standards of Ordinance No. GM/MS 888/2021, however, it operated for only 3 months during the year. Samples from wells 01, 03, and 04 meet the various aspects of the ordinance, requiring only chlorine treatability to meet all potability regulations. Well 05 does not meet all the standards of Ordinance No. GM/MS 888/2021, demonstrating samples that exceeded the VMP for turbidity, color, total hardness, and chlorides.

(2024-04-12) Oliveira, Samantha Ferreira Mendonça de; Marques, Sheyla Karolina Justino; http://lattes.cnpq.br/3917387578549073; Rapôso, Áurea Luiza Quixabeira Rosa e Silva; http://lattes.cnpq.br/7600867517446003; Peres, Ana Paula da Silva; http://lattes.cnpq.br/9975840346577976
The generation of waste in the Fiberglass Reinforced Plastics (FRP) industry and in Water Treatment Plants (WTP) is a serious environmental and social problem, due to the lack of areas to dispose of these liabilities, which become secondary raw materials for other industrial processes. In this context, the aim of this research was to analyze the characteristics and properties of GRP particulate (PPRFV) and water treatment plant sludge (LETA) in the production of porous ceramics, in order to obtain a more efficient product in the light of the circular economy. The waste was characterized using X-ray fluorescence (XRF), X-ray diffraction (XRD), Fourier transform infrared spectroscopy (FTIR), derivative and differential thermogravimetric analysis (TG/DTG/DSC) and scanning electron microscopy (SEM). Experimental traces were used with levels of PPRFV (0%, 4%, 6% and 8%) and LETA (5%, 10%, 15% and 20%), as a partial substitute for clay, in which 10 specimens were molded per composition. The data obtained from the response variables was submitted to analysis of variance (ANOVA) and polynomial regression. PPRFV showed a majority of CaO (47.79%) and SiO2 (36.38%), while LETA showed SiO2 (52.06%) and Al2O3 (29.83%). X-ray diffraction detected the presence of an amorphous halo and the quartz crystalline phase in PPRFV and LETA, in that order. The infrared of the PPRFV allowed functional groups that occur in the chemical structure of epoxy resin to be determined, while the sludge showed absorption bands characteristic of clay minerals. Thermal analysis of the particulate revealed an exothermic event at a temperature of around 450°C and a mass loss of 40.33%. The sludge suffered a total mass loss of 14.83%. SEM micrographs of the particulate revealed the existence of fibrous filaments adhered to the particles with a rough texture, while the sludge showed a chip-like shape, characteristic of materials with an organic and inorganic load. With regard to the technological tests, the experimental mix with 8% PPRFV and 20% LETA emerged as the most promising, showing an increase of 83.84%, 47.36% and 26.67% in the Linear Shrinkage, Water Absorption and Apparent Porosity indices, respectively, compared to the reference mix. The Permeate Flow data confirmed the increase observed in the physical tests, reaching a value of 5,222.27 L/m².h for the experimental mix with the highest percentage of waste. Based on the data obtained, this study proved to be important in the development of a technical product with a view to reintroducing GRP particulates and WTP sludge into the water treatment system at the filtration stage.
Análise das práticas de segurança do trabalho adotadas por cooperativas de reciclagem de resíduos eletroeletrônicos: um estudo multicasos
(2024-01-31) Pimentel, Karine Viviane de Araujo; Cunha, Mônica Ximenes Carneiro da; http://lattes.cnpq.br/1775024859845111; Souza Júnior, Marcilio Ferreira de; http://lattes.cnpq.br/2702843581642246; Cunha, Mônica Ximenes Carneiro da; http://lattes.cnpq.br/1775024859845111; Holanda, Romildo Morant de; http://lattes.cnpq.br/4283130448063981
The rapid increase in the production of electronic equipment has resulted in an increase in the amount of electronic waste produced annually in the world. To face this problem, in 2010, Brazil developed the National Solid Waste Policy (PNRS), which included reverse logistics as an instrument to deal with the growing flow of this type of special waste and gave recycling cooperatives a social role in this chain. . In this context, recycling cooperatives began to play an important role in the process of collecting and treating Waste Electrical and Electronic Equipment (WEEE). However, if handled and disposed of inappropriately, WEEE can pose environmental and occupational health risks to those who collect these materials. The objective of the research was to analyze the work safety practices adopted by WEEE recycling cooperatives. The methodological procedure was divided into three stages: (1) systematic literature review on occupational safety practices adopted in solid waste cooperatives; (2) multi-case study with 5 (five) WEEE cooperatives; (3) proposal for a manual of good occupational safety practices for WEEE cooperatives. As results, RSL uncovered 71 workplace safety practices, organized into three categories: 1) Personal Protective Equipment (PPE), 2) equipment that assists in ergonomics and well-being at work, 3) workplace safety actions and programs work. In the field research, it was possible to identify that the five cooperatives surveyed employed occupational safety practices in their processes and it was observed that, although safety practices are a legitimate concern for cooperative members, they tend to be simplified, with a focus on adoption of PPE as the main measure. Despite this, it was possible to identify actions to analyze work processes, implement specific training and pay attention to the prior analysis of equipment to be dismantled, characterizing safety precautions from the beginning of the process and contributing to the creation of a safety culture. A technical manual with good safety practices for cooperative members was also prepared, directly benefiting workers in the recycling sector with a safer and healthier working environment.

(Instituto Federal de Educação Ciência e Tecnologia de Alagoas, 2022-10-20) Carvalho, Juliana Lira Brito de; Marques, Sheyla Karolina Justino; http://lattes.cnpq.br/3917387578549073; Souza, Ronny Francisco Marques de; http://lattes.cnpq.br/7651317326903869; Rapôso, Áurea Luiza Quixabeira Rosa e Silva; http://lattes.cnpq.br/7600867517446003; Gondim, Priscylla Cinthya Alves; http://lattes.cnpq.br/7727315802596668
Due to its composition, post-consumer carton packs have great potential to be used as an input in the manufacture of new products. In this context, this research aimed to analyze the performance of partial replacement of fine aggregate by triturated carton packages in the development of a masonry mortar. The methodology was divided into the following steps: elaboration of a systematic literature review; collection, preparation and comminution of carton packages; characterization of raw materials; definition of the reference and experimental compositions; performance of technological tests; and analysis of results. In the fine aggregate, granulometric analysis was performed. The by-product, Triturated Cartons Packages (ECT), was characterized by Chemical Analysis by X-Ray Fluorescence (XRF) and Scanning Electron Microscopy (SEM). The proportion of 1:6 of volume of cement and fine aggregate was adopted as reference and experimental compositions were determined with substitutions of 5%, 10% and 15% of volume of aggregate by ECT, being molded and tested 5 specimens for each composition. The tests of Consistency Index, Compressive Strength, Water Absorption by Immersion and SEM of Fracture Surface were performed. It was carried out the correlation analysis between the average values of the properties and the percentage of ECT replacement. As for the results of the Consistency Index test, the mortars with ECT replacement showed a small reduction, but they remained in the range presented in the literature. Regarding Compressive Strength, the mortars with replacement of 5%, 10% and 15% showed average values of 7.57 MPa, 6.52 MPa and 6.07 MPa, respectively. Mortars with ECT showed a low rate of Water Absorption by Immersion, when compared to literature data. The statistical analysis revealed that all properties studied have strong correlation with the percentage of ECT replacement. The SEM of the Fractured Surface found the highest number of voids and the presence of microcracks in the samples with the highest percentages of ECT. Finally, the accomplishment of this study proved to be relevant in the context of the development of new technical materials, presenting to the market the mortar with triturated post-consumer carton packages.

(Instituto Federal de Educação Ciência e Tecnologia de Alagoas, 2021-07-21) Alves, Agripino Emanuel Oliveira; Cunha, Ana Catarina Monteiro Carvalho Mori da; http://lattes.cnpq.br/6533002613885833; Valente, Ellen Carine Neves; http://lattes.cnpq.br/5519733594584141; Martins, Ricardo Brainer; http://lattes.cnpq.br/9236216672510518; Dantas, José Oliveira
Storing food is a practice observed since the beginnings of production and agricultural exploitation, it is a fundamental strategy to ensure society's food for a certain period. Currently in agriculture, whether corporate or family, storage is used to ensure the quality of the product and trade. However, these stored and stored foods are targets of pests and insects that compromise production. Thus, measures to control and eliminate these pests are necessary, through various methods, whether with chemical or biological control. Therefore, this work aimed to analyze the bioinsecticide potential of essential oils extracted from Eucalyptus genotypes for the control of storage pests in the production of beans (Zabrotes Subfasciatus) and corn (Sitophilus zeamais), under laboratory conditions, using essential oils from 4 Eucalyptus genotypes (1249, 1250, 1277 and 0292). The oils were tested for repelling action and lethal concentrations for pest control. In the studies of mortality by contact of pest insects, 4 Eucalyptus genotypes were analyzed, with 3 different concentrations being for Z. subfasciatus (1%, 2%, 2.5%), and for Sitophilus zeamais (5%, 10%, 20%), plus one positive and one negative control, with 10 replicates in randomized blocks. For the free-choice repellent action studies on the pest insects Z. subfasciatus and S. zeamais, essential oils from 4 Eucalyptus genotypes were tested with 5 replications for each treatment, in a completely randomized block design. All tested oils showed repellent action on insects and were efficient in the mortality of insect pests Z. subfasciatus and S. zeamais.
Avaliação da qualidade ambiental do complexo estuarino lagunar mundaú-manguaba – CELMM, Alagoas: uma abordagem biológica e da paisagem
(Instituto Federal de Educação Ciência e Tecnologia de Alagoas, 2020-07-24) Silva, Robert Germano Alves da; Mayorga, María Angélica Pérez; http://lattes.cnpq.br/3725581918287088; Romero, Renato de Mei; http://lattes.cnpq.br/9857771457585862; Teresa, Fabricio Barreto; http://lattes.cnpq.br/2706179711969560; Sampaio, Cláudio Luis Santos; http://lattes.cnpq.br/2526336992077506; Araujo, Daniel de Magalhães; http://lattes.cnpq.br/5837261784524743
This dissertation presents two chapters that include environmental assessment methods applied in the hydrographic basins of the Mundaú-Manguaba Estuarine-Lagoon Complex – MMELC. Degradation in CELMM has considerable environmental and socioeconomic impacts on riverside communities. We discuss how environmental, physical and spatial changes are related to chemical descriptors and the ecological response of the ichthyofauna of streams inserted in the system, aiming to test environmental diagnostic instruments for monitoring and managing impacts on rivers and coastal streams. Chapter I presents the application of the Habitat Integrity Index, a local physical assessment (80 m) already consolidated, and two proposals, one for adapting an index for landscape (1.6 km) and another for an index integrated to the two scales to equalize possible distortions. To understand the biological responses to the index values, two ecological estimators were evaluated species richness and percentage of Poecilia reticulata, in the fish community. The results are discussed in order to evaluate the ability to describe the indexes and estimators for local physical, spatial and biological characteristics. In Chapter II, the physical and chemical descriptors of the stream and ecotone were integrated with ecological descriptors. We tested the application of the Abundance and Biomass Curves (ABC) and the W statistic in the biological evaluation to detect environmental disturbance in the streams. The indicator species analysis (IndVal) was used to describe the species that characterize each land use and occupation group, and the Redundancy Analysis (RDA) was performed to identify the chemical and physical descriptors that structure the fish communities for each land use and occupation. In general, the evaluation methodologies used were able to describe the differences in the environments for each land use and occupation and relate the physical and chemical structuring of the streams to the fish community.
Avaliação da viabilidade técnica, econômica e ambiental da produção de piso intertravado com agregado da concha de sururu
(Instituto Federal de Educação Ciência e Tecnologia de Alagoas, 2023-11-30) Tenório, Arthur Amaral Batista; Marques, Sheyla Karolina Justino; http://lattes.cnpq.br/3917387578549073; Rapôso, Áurea Luiza Quixabeira Rosa e Silva; http://lattes.cnpq.br/7600867517446003; Peres, Ana Paula da Silva; http://lattes.cnpq.br/9975840346577976
In this study, the sustainable reuse of Sururu shells (Mytella falcata) in civil construction was explored, highlighting not only the approach to environmental problems resulting from inadequate disposal, but also the promotion of local partnerships that generate jobs and boost the regional economy. The present invention consisted of analyzing the interlocking floor with partial replacement of the fine aggregate (natural medium sand) with grains of Sururu shells. A sustainable approach was sought, analyzing technical, economic and environmental feasibility. Detailed physicochemical analyzes were carried out, including Granulometry, X-ray Fluorescence (XRF), X-ray Diffraction (XRD) and Thermogravimetric Analysis (ATG), to characterize the properties of the shells. When defining the concrete mix, a volume ratio of 1:2.33:0.37:2.00:0.43 (cement: sand: crushed stone powder: crushed stone 0: water) was established. Various sand replacement formulations were also examined, varying between 2.5%, 5.0%, 7.5% and 10.0%. During laboratory tests, the results met technical specifications favorably. The C-5% composition presented a compressive strength of 37.87 MPa, meeting the technical requirements established by the standard for concrete pieces intended for paving, which requires resistance equal to or greater than 35 MPa. Water absorption tests demonstrated effectiveness in promoting adequate drainage, with water absorption variations within the acceptable range, remaining below 0.77%. These results highlighted the potential of Sururu shells as a source of technical, economic and environmental interest in the manufacture of interlocking pavements. This study not only contributed to the development of innovative technical materials in the interlocking flooring market, but also emphasized the importance of sustainable practices in construction and reinforces the Circular Economy.
Avaliação de resíduo sólido como mulching alternativo e de agrofilmes na produção de alface na região semiárida de Alagoas
(Instituto Federal de Educação Ciência e Tecnologia de Alagoas, 2021-12-30) Barros, José Anderson Soares; Cavalcante, Marcelo; http://lattes.cnpq.br/0221717690546039; Costa, Joao Gomes da; http://lattes.cnpq.br/2787724876009177; Santos, Márcio Aurélio Lins dos; http://lattes.cnpq.br/0192590447392368
The Soiltain DW® geosynthetic blanket is used in water treatment plants, in water filtration, has a shelf life of three months, in which it is then disposed of in sanitary landfills. Due to its characteristics, it consists of a solid residue with potential for agricultural use, as ground cover. This practice, known as mulching, common in plasticulture in temperate regions, reduces water losses, the incidence of weeds and labor. However, it can promote soil microclimate, especially in tropical and semi-arid regions, causing stress to plants. Therefore, the objective of this research was to evaluate the technical and economic feasibility of the Soiltain DW® geosynthetic blanket as an alternative mulching and the use of synthetic agrofilms in the production of lettuce cv. ‘Veneranda’ in Arapiraca, semi-arid region of Alagoas, Brazil. Four experiments were carried out between June/2020 and March/2021, in a completely randomized design, with four treatments (geosynthetic blanket, white and black polyethylene mulching, and bare soil) and five replications. The technical viability of the coverings was determined from the evaluation, at the end of each experiment, of the soil temperature, stand and morphoagronomic variables. Univariate and multivariate analyzes and Pearson’s correlations were applied. In the analysis of economic viability, indicators were used, from the cash flows between income and expenses, gross income, net income, profitability index and internal rate of return. There was a significant effect (P<0.05) for the interaction Soil cover x Planting times for all variables, except for root mass, indicating that these factors, together, promote changes in the behavior of lettuce cv. ‘Veneranda’. Univariate and multivariate analyzes showed the influence of mulching on lettuce in the four experiments, indicating that white mulching promoted favorable conditions for the evaluated morphoagronomic variables, promoting the highest yields in all cycles (average 19.9 Mg ha-1 ). Temperature is the response variable that exerted the most negative influence, mainly on stand, in which geosynthetic blanket and black mulching showed similarity, due to greater absorption of solar radiation and stand reduction. There is economic attractiveness for all the coverages studied, as there is a result that provides an economic return on the capital invested from the 2nd cropping cycle, when there is economic coverage of the initial investment value and coverage of the minimum attractiveness rate. The economic analysis showed that the geosynthetic blanket promoted the lowest effective operating costs, intermediate net income and lower profitability only than white mulching in the sum of the four experiments. Therefore, the four treatments evaluated are economically viable, especially white mulching. The Soiltain DW® geosynthetic blanket, solid waste, as it is free and reusable, can be used as an alternative mulching on lettuce cv. ‘Veneranda’, in the edaphoclimatic conditions of Arapiraca/AL.
Boas práticas de manipulação, condições higiênico-sanitárias e composição mineral de sururu (Mytella falcata) comercializado em feiras livres de Alagoas
(Instituto Federal de Educação Ciência e Tecnologia de Alagoas, 2022-07-29) Lucena, Vívian da Silva Santos; Araujo, Daniel de Magalhães; http://lattes.cnpq.br/5837261784524743; Freitas, Johnnatan Duarte de; http://lattes.cnpq.br/4999402869058858; Lopez, Ana Maria Queijeiro; http://lattes.cnpq.br/4034568781881997; Tamano, Luana Tieko Omena; http://lattes.cnpq.br/4206868438935017
Sururu (Mytella falcata) is the main fishing resource of the Mundaú-Manguaba Estuarine- Lagoon Complex (MMELC), being a fundamental product for generating income for tens of thousands of families that live in the surroundings of the lagoons. In addition to its natural propensity to accumulate contaminants present in the aquatic environment, such as toxic metals, the handling of sururu is inadequate, from the subsequent stages of its collection to its disposal in the commercialization places. The present study aimed to carry out a diagnosis of good handling practices, hygienic-sanitary conditions and mineral composition of sururu in street markets in the municipalities bathed by the lagoons that make up the MMELC. For that, a checklist was prepared and applied to guide the observation of the hygienic conditions of the facilities, equipment and utensils used, handling and way of exposing the product, clothing and use of personal protective equipment, and waste disposal, among others, at the fairs in Maceió (Tabuleiro), Marechal Deodoro, Pilar, Satuba and Rio Largo. For the investigation of minerals, samples were acquired from all points of sale found in the fairs of the aforementioned municipalities. After procedures to obtain the extracts by acid digestion, the concentrations of iron (Fe), copper (Cu), manganese (Mn) and zinc (Zn) were analyzed, using the atomic absorption spectrophotometry technique, and lead (Pb), following the corresponding protocol of the Standard Methods for the Examination of Water and Wastewater (SMEWW). With the application of the checklist, it was possible to classify the hygienic-sanitary conditions in all the fairs visited as unsatisfactory. Despite this, it is worth noting that the highest percentages of adjustments were observed at the Rio Largo fair, where the assignment of space for commercialization was conditioned to participation in a training course in good food handling practices, offered by the municipality. The research also involved the application of a questionnaire for the socioeconomic characterization of the vendors. It could be noticed the predominance of female vendors, with low schooling, the sale of sururu and/or other fish as the only source of income, reaching a value close to the minimum wage. As for the micromineral composition, iron showed the highest concentrations in all samples, surpassing by more than fifteen times the values detected for copper, manganese and zinc. Regarding the toxic metal lead, the samples were within the limit allowed in bivalve molluscs. The results obtained with this work confirm the importance of sururu for countless families who sell it in open markets to earn a living and reinforce the need for a joint effort, by the market vendors and those responsible for managing these spaces, to provide the population of these locations with an environment conducive to commercialization of food. In addition, it is necessary for the competent authorities to continuously investigate the levels of highly toxic trace elements in the MMELC, so that the benefits of the consumption of sururu by the population are not counterbalanced by the risk of contamination.
Caracterização do recinto de aclimatação marinho para peixes-bois (Trichechus manatus manatus) no Ceará : uma inovação tecnológica para o manejo da espécie no Brasil
(INSTITUTO FEDERAL DE ALAGOAS - Ifal, 2025-01-23) Bezerra, Brunno Torres de Gouveia; Normande, Iran Campello; Romero, Renato de Mei; https://orcid.org/0000-0001-6196-6122; http://lattes.cnpq.br/9857771457585862; Choi, Katherine Fiedler; Marques, Sheyla Karolina Justino
For many years, the West Indian manatee (Trichechus manatus manatus) was classified as Critically Endangered in Brazil and recognized as the most vulnerable aquatic mammal in the country. To support its conservation, strategic actions such as rescue, rehabilitation, and release of manatees into the wild have been carried out since 1994 in northeastern Brazil, with the aim of repopulating areas of historical occurrence, reconnecting isolated populations, and strengthening existing population nuclei. As part of these strategies, the Association for Research and Preservation of Aquatic Ecosystems (Aquasis) implemented, in 2020, a new model of a marine acclimatization enclosure in Icapuí, Ceará, pioneering as the only structure of its kind located in a marine environment in Brazil. Consisting of a floating platform with a net-tank system, the enclosure was developed to initiate the acclimatization and release process of manatees rescued and rehabilitated by Aquasis in the state of Ceará, as part of conservation strategies for the species. In 2024, the structure of the acclimatization enclosure was expanded with the installation of a surrounding fence, forming a polygonal contour area resembling a traditional fish corral, encircling the floating platform throughout the perimeter of the polygon. This study aims to characterize the marine acclimatization enclosure used for manatee adaptation in Icapuí, Ceará, as well as to analyze other existing acclimatization enclosures in Brazil. The research compares different manatee acclimatization systems used in the country, detailing their construction features—including the floating platform and fence—describing feeding management practices, capture and handling methodologies, developing a schematic representation of the acclimatization enclosure, and proposing improvements aimed at enhancing animal welfare. The implementation of the marine acclimatization enclosure represents an innovative and strategically important structure for manatee conservation, highlighting its operational features. The results underscore the Icapuí marine acclimatization enclosure as an innovative and replicable model with the potential to expand the positive impact on species conservation.

The planet's population has been growing consistently over the decades. The most recent pro- jections indicate that in the next ten years we will have an increase of 80 million people and that this number will only increase in the following decades. This fact will bring a series of challenges and among them we can mention the need to produce food for this large number of people without compromising the environment even further. Each year, the agricultural harvest in Brazil has been breaking records, in the same way that the use of agricultural pesticides is increasing in the same direction. If these substances are not used appropriately, they will quickly harm the environment and monitoring becomes increasingly necessary. This monitoring is car- ried out through chemical analysis. Raising awareness among new generations about problems related to environmental degradation is important and this can be done in chemistry classes. As is well known, carrying out practices in the laboratory makes learning easier and more effective. In this sense, carrying out practical classes requires essential equipment: a potentiostat. This equipment is expensive and its use is mostly restricted to research laboratories. This research sought to develop a potentiostat capable of carrying out electrochemical analyzes with the main characteristics being its low cost, ease of manufacture and portability where its focus is not on carrying out analyzes with great precision to be used in classes for the quantification of internal contaminants. -environmental stress. We searched the literature for projects that included some of these characteristics to promote adaptations and improvements with the aim of minimizing costs. The equipment developed was subjected to calibration using the electrical resistance method to verify its compliance with Ohm's law. It presented a difference of +/- 0.14% in rela- tion to a fictitious resistance compared to a difference of +/- 0.1% presented by a commercial potentiostat. Improvements in the future such as improving the software with the insertion of new electrochemical techniques, modifying the microcontroller (Arduino pro mini, or similar and developing another communication cable.

The study addresses artisanal fishing in the Marine Extractive Reserve (RESEX) of Lagoa do Jequiá, highlighting the role of fishers' ethnoecological knowledge and the use of technologies to track fishing activities. The research combined semi-structured interviews, GPS tracking, and fleet counting via drones to understand fishing strategies, spatial patterns, and fishers' perceptions of environmental changes. Six fishing methods and 54 captured species were identified, revealing a strong relationship between the techniques used and the characteristics of the exploited areas. The results indicate that fishing activity is in decline, partly due to the aging fishing population and a lack of infrastructure and government support. The study also suggests that, although no tracked vessels operated within the RESEX, there are indications of fishing in protected areas during the dry season, a hypothesis that requires further investigation. Integrating local knowledge with spatial data is essential for planning marine protected areas, promoting sustainable management, and reducing conflicts between conservation and artisanal fishing.

(INSTITUTO FEDERAL DE ALAGOAS - Ifal, 2025-01-23) Cavalcante, Kledson Marques; Maia, Stoécio Malta Ferreira; http://lattes.cnpq.br/6110419050119583; Salomon, Karina Ribeiro; https://orcid.org/0000-0002-5008-0497; http://lattes.cnpq.br/3169357924019841; Silva, Eunice Palmeira da; http://lattes.cnpq.br/4679066494213977; Wanderley, Lucas Suassuna de Albuquerque; http://lattes.cnpq.br/0018963581369746
This study evaluated the impact of the COVID-19 pandemic on greenhouse gas (GHG) emissions from the Federal Institute of Alagoas (IFAL), comparing the years 2019 and 2022. The research is justified by the need for educational institutions, such as IFAL, to adopt sustainable management practices to mitigate the effects of climate change, as foreseen in the National Climate Change Policy. The study focused on GHG emissions related to fuel consumption, refrigerant gases, electricity consumption, and waste generation. The results indicated an overall reduction of -7.8% in IFAL's GHG emissions, mainly due to the decrease in face-to-face activities and the maintenance of changes in work methods adopted during the COVID-19 pandemic. Direct GHG emissions (scope 1), related to the consumption of fuels and refrigerant gases, showed variations in the evaluated period (-9.1% and 20.4%, respectively). Indirect GHG emissions (scope 2), associated with electricity consumption, showed a variation of -54.8%, influenced by the reduction in face-to-face activities and the improvement in the emission factor of the National Interconnected System. Other indirect GHG emissions (scope 3), such as the generation of urban solid waste and liquid effluents, also showed an overall reduction (-2.1% and -3.4%, respectively). The study concluded that modernizations of work processes, driven by the COVID-19 Pandemic and maintained after the return to in-person activities, impacted the reduction of GHG emissions by IFAL. The research recommends the improvement of sustainable management practices, mainly through monitoring resource consumption and GHG emissions, investing in energy efficiency, optimizing transportation, and digital technologies. The adoption of these measures will contribute to consolidating IFAL's commitment to environmental sustainability and social responsibility.
Hotelaria e desenvolvimento sustentável: uma análise contemporânea à luz das práticas ambientais
(Instituto Federal de Educação Ciência e Tecnologia de Alagoas, 2022-04-29) Maia, Carolina Ferreira Simon; Tonholo, Josealdo; http://lattes.cnpq.br/6333407087554681; Lages, Vinicius Nobre; http://lattes.cnpq.br/0525380988317234; Gomes, Fábio Guedes; http://lattes.cnpq.br/6641021807409592; Rocha, André Leite; http://lattes.cnpq.br/1335590978899886
The hotel industry, important economic activity for any location exploiting tourism, generating employment and income at all levels of professional qualification, and provides opportunities for several direct and indirect jobs. In addition to this is its close relationship with the environment, revealing itself as an opportunity for competitive differentiation in its offer. At the same time, it has a high consumption of resources for its operation, the sector has recognized potential to contribute to sustainable development (SD). It can reduce its negative environment impacts and meet the demands of a market that is increasingly sensitive to these issues. The present study carried out a systematic literature review (SLR) and a survey of the actions employed by the hotel sector, with the objective of analysing the existing world literature and business scenario on the adoption of environmental practices/ technologies, considering the last five years. The methodology used was an exploratory-descriptive study, developed in two stages: (i) SRL that resulted in a portfolio of articles, enabling bibliometric and systematic analysis through the reading of the articles guided by the three dimensions of SD; and (ii) research on the sites of the largest global and Brazilian hotel chains to identify the corporate actions that are being runned on this topic. With the results, it is observed that in the recent years there has been an increase in the number of studies and initiatives related to sustainability in hotel enterprises, with the adoption of socio-environmental practices/ technologies and effective changes in their organizational cultures. A significant number of environmental certifications and organizations acting as a reference on this topic were also identified. In the business sphere, it became evident that while the hotel sector worldwide demonstrates strong commitment to sustainability, in Brazil national enterprises cannot yet be perceived as protagonists in the irreversible process of global business dynamics. If there are actions, they are not being shared with society structured and systematically. Among other possible models, the Technical Guide is presented as a Technological Technical Product (TTP) generated from this study.

(2025-01-24) Santos, Gabriela Moreira dos; Cruz, Nicholas Joseph Tavares da; https://orcid.org/0000-0003-0765-5424; http://lattes.cnpq.br/6913208549056992; Souza Júnior, Marcilio Ferreira de; http://lattes.cnpq.br/2702843581642246; Romero, Renato de Mei; http://lattes.cnpq.br/9857771457585862; Silva, Claudionor de Oliveira; http://lattes.cnpq.br/7914499903341694
Disorderly urban expansion, lack of adequate planning and the absence of modern infrastructure in public cemeteries contribute to a series of problems that affect both public health and the environment. These spaces have attracted attention due to their potential for environmental pollution and are seen as sources of contamination, and their activities are subject to environmental licensing, as provided for in the resolutions of the National Environmental Council. There is a possibility of soil degradation and water contamination by leachate and solid waste, which threaten human health and the environment and require solutions capable of reducing the impacts attributed to cemetery activities. This research aimed to describe the socio- environmental impacts of public cemeteries in cities in the state of Alagoas based on the analysis of solid waste generation and environmental disposal thereof. A qualitative methodological approach was adopted through the multi-case study strategy, limited to 12 (twelve) public cemeteries in the intermediate geographic region of Maceió-AL. The methodological procedures involved a systematic literature review on the issue, followed by observational research in public cemetery environments, where data were collected from non- participant observations and photographic records. As a result of the SLR, based on the extraction of data from 27 primary studies identified as relevant by the search string, the most mapped types of cemetery solid waste were construction waste and exhumation remains; the proposed interventions involved the development of management plans, environmental education, and maintenance and cleaning of the sites; in addition to the adoption of new cemetery practices. As a result of the observational research in the field, the lack of adequate infrastructure in the cemeteries was evidenced, aggravating the environmental problems with pollution by leachate and solid waste from exhumations without adequate disposal.
