Sustainable procurement in the Brazilian federal public administration: a scoping review
This study presents a scoping review of the literature on the implementation of sustainable public procurement (SPP) in Brazilian public administration. Given the growing importance of sustainability in public policies, this review aims to understand SPP in Brazil through published studies and to identify gaps in the existing research. Using the PRISMA-ScR statement, 55 studies published between 2011 and 2024 were analyzed, selected from international databases such as Web of Science, Scopus, and SciELO, as well as Brazilian databases like SPELL and CAPES Periodicals Portal. The descriptive analysis revealed increasing academic interest in SPP within Brazilian public administration, with variations in output over the years and concentrated in journals from the fields of public administration, environmental management, and applied social sciences. The content analysis revealed that the studies are grouped into four categories: sustainability criteria; capacity building of public agents; challenges and barriers; and impacts and outcomes. Findings include the identification of common barriers, such as the need for clear sustainability criteria, and potential enablers, such as regulatory support and budgetary allocation. Additionally, ongoing training for public agents was considered crucial for effective implementation of SPP. These results aim to contribute to achieving the Sustainable Development Goals, especially target 12.7, which relates to the promotion of sustainable public procurement.

Perspectives on biogas production from microalgae for circular economy: a bibliometric analysis
The growing global energy demand and the environmental impacts associated with fossil fuel use have driven the development of renewable alternatives, such as bioenergy. Microalgae stand out as a promising raw material for biogas production, aligning with circular economy principles. This study presents a bibliometric analysis of biogas production from microalgae. An exploratory review of 60 articles indexed in the Web of Science (WoS) database from 2015 to 2025, using the terms “microalgae,” “biogas,” and “anaerobic digestion,” with data processing performed using VOSviewer software. Results revealed a concentration of publications in India and a noticeable gap in Latin American and Brazilian research. The most prominent subject areas included energy fuels, environmental sciences, and biotechnology applied microbiology. Co-occurrence analysis identified 29 relevant keywords, with “biogas” and “microalgae” showing strong thematic links. The bibliometric mapping grouped studies into four thematic clusters: biogas production from microalgae, biomass production, environmental issues, and energy-related topics. Seven key articles were highlighted, demonstrating the potential of microalgae as a sustainable energy source, while also addressing technical challenges such as rigid cell walls, the need for pretreatment methods, and the advantages of co-digestion to improve methane yields. The findings suggest that, despite the technical and environmental potential, the integration between biotechnologies, circular economy, and public policies can broaden the prospects for the application of this technology. In this sense, the adoption of an interdisciplinary approach that links waste management, environmental regulation, and economic viability is essential to consolidate the use of microalgae as a sustainable bioenergy source.

Water quality in healthcare facilities: a narrative review with an emphasis on risk prevention
The presence of pathogens in drinking water is a significant concern in healthcare facilities (HCFs), as it can contribute to infections and hospital-acquired diseases. Ensuring that water meets potability standards is essential for the safety of healthcare procedures, protecting patients and maintaining biosafety. In this context, this literature review aims to explore existing approaches in the scientific literature regarding water quality control in HCFs in relation to biosafety and the prevention of contamination risks associated with water quality. Data were extracted from online databases, resulting in the selection of 17 scientific studies published between 2004 and 2024. The findings indicated an increase in the number of studies on this topic in recent years, highlighting results in water samples unfit for human consumption and therefore unsuitable for use in healthcare procedures due to contamination by microbiological indicators. The potential risk to patient health reinforces the importance of implementing surveillance programs to monitor water quality in HCFs. In this context, the complexity of the challenges faced by HCFs requires a meticulous analysis of the strategies adopted to ensure water quality at all stages of water quality control processes within healthcare facilities, with the aim of risk prevention.

Governance of Common Bens for Regional Development: the case of Jacupiranga Mosaic in Vale do Ribeira/SP
The present study aims to understand how the creation of the Jacupiranga Mosaic (Mojac) can be interpreted as a form of governance oriented toward the common good, considering sustainable development, land tenure conflicts, and the role of local communities, especially quilombola communities, in the Vale do Ribeira region, São Paulo. The analysis is grounded in theoretical frameworks on shared governance and based on a documentary survey of legislation, public policies, and news reports, as well as interviews with nine actors directly involved in the Mojac, including representatives of traditional and quilombola communities, local managers, and farmers. The study also involved in situ observation of two quilombola communities in the region. The study assumes that territorial conflicts stem not only from opposing interests but also from the historical denial of territorial and cultural rights of local populations. The results indicate that, although the Mojac represents a significant effort to coordinate different sectors and objectives such as environmental conservation and sustainable resource use, its effectiveness is constrained by structural challenges. These include limited representativeness in management councils, difficulties for quilombola and traditional communities to access decision-making spaces, scarce resources, and conflicts between conservation goals and local economic practices. It is concluded that the Mojac constitutes a promising initiative but still needs to overcome institutional barriers and strengthen its participatory base to consolidate itself as a governance model oriented toward the common good, capable of integrating environmental conservation with recognition of quilombola and traditional ways of life in the Vale do Ribeira.

Commercial establishments and waste of medications and disused products in the municipality of Soledade, RS: Environmental approach
Improper disposal of unused and discarded medicine waste is an environmental and public health problem and therefore, its proper management contributes to maintaining environmental quality. Thus, this study aims to analyse environmental aspects associated with disposal of medication waste and disused drugs in the municipality of Soledade-RS and the practices adopted by commercial establishments for their management. The method used included the application of a questionnaire with 10 questions (open and closed) in 16 commercial establishments located in the municipality. The establishments were characterized and classified according to type and number of daily appointments, respectively. Regarding this characterization, the following were included: 4 commercial pharmacies, of which three are located in the Centro neighborhood and are classified as Large Size and one in the Fontes neighborhood, classified as Medium Size; 2 compounding pharmacies, located in the Center, one of which is small and the other medium-sized; and 10 drugstores, one located in the Botucaraí neighborhood, considered small, while the other nine are located in the Center neighborhood, of which three are considered small, two are medium-sized, and three are large. The municipality of Soledade is not legally required to provide fixed collection points for medication waste, but even so, 12 locations (75%) claim to provide these collectors. It is noteworthy that only 2 establishments had identified access to the consumer. The lack of information at the time of purchase can influence the destination given to medication waste, and 40% of the establishments are not providing this type of information.

Applicability of WTP sludge for sealing barriers in landfills
Water treatment plant (WTP) sludge is a waste product generated during the water treatment process and is made up of a mixture of organic and inorganic materials, which, when disposed of inappropriately, harms water and soil quality. Despite its harmfulness, WTP sludge can be reused, which reduces the negative environmental impacts inherent in its finais disposal. Mixtures of soil and WTP sludge can be used in various stages of landfill construction and operation, such as sealing barriers. These barriers consist of lining and waterproofing systems and prevent the migration of leachate generated by the decomposition of solid waste disposed of in landfills. The aim of this research was to analyze the application of soil-sludge mixtures (10% and 20%, by weight) as an alternative in the composition of sealing barriers in a landfill through geotechnical tests of the soil and soil-sludge mixtures in order to analyze their properties and feasibility. For this purpose, the mixtures were subjected to tests to determine the specific gravity of the particles, particle size distribution, Atterberg limits, maximum dry density and optimum moisture content, permeability, and elemental composition. The experimental results showed an improvement in the soil properties with the incorporation of sludge, making it more plastic, with greater optimal moisture and lower density, thus having properties more suitable for use in a sanitary landfill.

Grain size stabilization of soil with red clay for impermeable layers in sanitary landfills: a case study
Currently, the most common method for the final disposal of Municipal Solid Waste (MSW) is sanitary landfill, which typically includes base and cover liners constructed with clayey soil. These liners aim to mitigate environmental impacts associated with the biodegradation of MSW. This study conducts geotechnical analyses using soil mixtures to determine the optimal composition for application in the base and cover liners of a sanitary landfill. The study was conducted at the Vale do Jaguaribe Sanitary Landfill under construction in Limoeiro do Norte - CE, using samples of natural soil and clayey soil collected from Russas - CE. Mixtures containing 40% and 50% clayey soil were prepared for geotechnical characterization, saturated permeability coefficient determination, and chemical and mineralogical analyses. The results indicated hydraulic conductivities of 7.13 × 10⁻⁷ m/s for the natural soil and 1.40 × 10⁻⁸ and 6.70 × 10⁻⁹ m/s for the mixtures with 40% and 50% clay, respectively, in samples compacted using Standard Proctor energy at the maximum dry density and optimum moisture content. It is concluded that the natural soil from the landfill site, when mixed with clayey soil, can be used both in the base liner system and in the cover layer of sanitary landfills, depending on the type of MSW.

The relationship between biodigesters and air quality: a qualitative bibliometric review
The livestock production sector can contribute to renewable energy generation and the reduction of pollutant emissions through the use of biodigesters that process poultry, swine, and cattle manure into biogas and biofertilizer. This study aims to explore the relationship between biodigesters and air quality through a qualitative bibliometric analysis. For this purpose, the research databases used were: ScienceDirect; open access & open archive; and research article, applying the search descriptors: air quality AND biodigester. The search resulted in 87 articles. Co-occurrence analysis and the construction of the bibliometric map were conducted using the software VOSviewer. Fourteen keywords related to the study objective were selected for the bibliometric analysis: carbon credit, ecosystem service, renewable resource, biomass bioenergy, Africa Biogas Partnership Program, air quality, mitigation, energy transition, responsibility, local community, emission reduction, energy self-sufficiency, biodigestate, and electricity demand. The terms air quality and energy transition accounted for 8.9% and 16.8% of occurrences, respectively, based on the total of 524 keyword occurrences. Eight Brazilian articles were identified. Therefore, biodigester technology enables both the recovery of air quality and access to electricity in rural areas, promoting improved living conditions, health, and well-being for rural producers. Although the direct association between biodigesters and air quality remains underexplored in the scientific literature, there is consistent evidence that this technology significantly contributes to the reduction of polluting and odorous gas emissions, thereby enhancing environmental health.

Motivations, challenges and benefits related to the quality management system based on SiAC
This article aimed to identify motivations, challenges, and benefits related to the quality management system based on SiAC. To achieve this, a case study was conducted at a construction company in the Recife Metropolitan Region, involving interviews with the QMS analyst, a director, and a construction engineer. Unlike the findings commonly reported in the literature, this study revealed distinct motivations, challenges, and benefits. Motivations included improving client confidence, increasing revenue, and further professionalising the company’s internal structure. Key challenges involved supplier quality issues, difficulties in interpreting the regulatory framework of SiAC’s Level A, managing extensive documentation, aligning organisational processes with regulatory requirements, and—most notably—adapting SiAC to meet the provisions of NBR 15575:2021. The reported benefits included successful implementation of the process approach and enhanced performance of delivered projects. This study also offers practical insights for construction companies initiating QMS implementation: the importance of regular awareness campaigns coupled with Daily Quality Dialogues, to address employee disengagement; with the system; continuous training on SiAC and the formation of a study group to reduce misinterpretation of its content; and the proactive application of supplier relationship management principles to improve the quality of products and services.

Implementation of the circular economy in Ecuador: a case study analysis
Circular Economy (CE) has emerged as a key strategy to address global challenges related to the unsustainable use of natural resources and the environmental impacts of the linear economic model. CE seeks to maximize the utility and value of resources for as long as possible, which has led to its inclusion in various regulatory frameworks. In Ecuador, CE has gained growing interest in recent years, driving new initiatives and becoming increasingly integrated into public policy. In this context, the study provides a comprehensive overview of CE and its implementation at the local level. To achieve this, a systematic literature review of 28 case studies in Ecuador was conducted. The results show that CE encompasses a wide range of sectors, actors, principles, and strategies. Additionally, the study identifies opportunities arising from governmental interest in promoting CE through new business models based on waste valorization. However, challenges remain, including the lack of coordination between sectors and key actors, limited access to financing, and the absence of standardized metrics to evaluate circular progress and support evidence-based decision-making. Moreover, although many CE initiatives are aligned with the Sustainable Development Goals (SDGs), only a few explicitly establish this connection. These findings highlight the need to strengthen regulatory frameworks, develop effective measurement tools, and promote cooperation among stakeholders to consolidate the implementation of CE in Ecuador.

Carboxylic acids produced by anaerobic digestion: sugarcane and cassava
This research investigated the production of carboxylic acids (CA) by anaerobic digestion (AD) using organic agro-industrial waste from Brazil. Two experimental routes were tested: Route A for biogas production with active archaea and Route B for CA production with inhibited archaea, using different pH conditions to suppress methanogenesis. The residues analyzed were sugarcane filter cake and cassava peel processing residues, with bovine manure as inoculum. The concentration of short-chain carboxylic acids (SCCA) was evaluated over 21 days using gas chromatography with flame ionization detection (FID). The most significant values were observed for acetic acid (43%) and butyric acid (40%) contents, increasing on day 4 of the experiment from route A to route B in the case of acetic acid from 51 mg/gMSO to 294 mg/gMSO, and in the case of butyric acid from 15 mg/gMSO to 197 mg/gMSO, respectively, when using sugarcane filter cake from the Brazilian sugar-energy sector. This suggests that sugarcane filter cake may be an effective substrate due to its rich organic content and favorable fermentation characteristics. On the other hand, CA production from cassava peel was low (0%) under the experimental conditions tested for acid contents, probably due to its limited nutritional composition. These results highlight the potential of sugarcane bagasse as a promising raw material for the sustainable production of AC through AD with methanogenesis inhibition, contributing to the development of renewable energies and bioproducts.

Solid waste and recycling associations: Overview of Management in the municipality of Erechim and socio-environmental challenges
Recycling associations are responsible for a set of actions at different stages with solid waste. In this sense, this research aimed to analyze the urban solid waste management system in the municipality of Erechim/RS, focusing on the collection and segregation process involving these associations. Additionally, this study also sought to identify the challenges and main difficulties by determining the qualitative and quantitative indicators related to the waste generated and collected. For this, the following steps were necessary: (i) bibliographic research and document analysis, (ii) description of the study area; and (iii) evaluation of the operationalization of the collection and segregation system of recyclable materials, carried out by the associations. With 6 associations, the municipality stands out when compared to the national reality in the following indicators: a) average monthly productivity per worker; b) average remuneration and c) % of plastic marketed. Problems associated with the previous collection stages were observed, bringing health risks to these workers and leading to a loss of economic value for these materials, evidencing the need for greater community engagement in waste generation. In light of this, there is a clear need for increased support for the community through Environmental Education, while strengthening and extolling the actions of waste picker associations through municipal public incentives. This is necessary due to the evident devaluation workers by society, despite their fundamental role in implementing the principles of the National Solid Waste Policy.

Sustainable Logistics Plan in Public Institutions: A Systematic Literature Review
This article conducts a systematic literature review on Sustainable Logistics Plans in Brazilian public institutions, highlighting the growing relevance of the topic since the 1972 Stockholm Conference, which was a milestone for global awareness on sustainability, encouraging the integration of sustainable practices, especially in public administration. The implementation of the Sustainable Logistics Plan in Brazil, initially regulated by Decree No. 7.746/2012 and currently adjusted by Law No. 14.133/2021 and Ordinance SEGES/ME 8.678/2021, aims to promote efficiency in public procurement, balancing economic, social, environmental, and cultural aspects. This article systematically reviews the literature on the PLS, seeking to consolidate knowledge, identify successful practices, challenges, and research gaps on the topic. The research employed a qualitative methodology, with a systematic literature review conducted using the Parsifal tool and databases such as Web Of Science, Scopus, and IBICT, resulting in the analysis of 17 relevant scientific articles. The results reveal a growing, yet still limited, academic interest in the importance of the PLS in Brazilian public institutions and that the main practices adopted include selective collection, waste management, rational use of water and energy and sustainability in public procurement. On the other hand, the main challenges to be overcome are the need to integrate sustainable actions in a coherent way across all areas of the institutions, and the lack of training for civil servants.

Assessment of Environmental Awareness in Brand Consumption among UFAM Business Students
With the increase in environmental catastrophes and the intensive exploitation of renewable and non-renewable natural resources for economic development, it is essential to rigorously address environmental issues and promote a cultural shift that prioritizes sustainability and environmental preservation. Based on this problem, the present study aimed to measure the level of environmental awareness among students through their habits and intentions when consuming products. To this end, a quantitative survey was conducted with 135 students from the Federal University of Amazonas (Manaus campus), specifically from the Administration program. The study results indicate that these university students have a tendency to adopt sustainable behaviors in their consumption choices and are committed to continuing these practices more earnestly in the future. However, in some aspects, reluctance, contradictions, and neutrality were observed, which may be associated with various factors that hinder the formation of habits that can be considered truly sustainable.

Characterization and thermal analysis of metalworking sludge as a partial substitute for clays in ceramic production
This study evaluates the feasibility of using sludge from the metalworking industry (SMWI) as a partial substitute for clays in producing red ceramics for civil construction. The analysis of the white goods production process predicted the components of SMWI, potentially reducing the need for additional chemical analyses. According to the chemical analyses provided, SMWI is a non-hazardous solid waste, but not inert, due to the presence of aluminum, chlorine, and phenols, by Brazilian standards. The oxide composition of SMWI showed compatibility with the studied clays and data from the literature, suggesting its potential as an additive in ceramics. Rich in CaO and Al2O3, SMWI can enhance the mechanical strength of ceramics, although excessive addition may increase water absorption. Loss on ignition tests, thermogravimetry, and SEM-EDS analyses on SMWI and pure and 5% SMWI-added clays revealed the loss of volatile compounds and the formation of thermostable clay minerals. However, its distinct composition, with lower levels of Fe2O3 and SiO2, and the need for adequate homogenization, requires caution to avoid impacts on the final properties of the ceramic products, such as water absorption and mechanical strength. Thus, the use of SMWI as a ceramic additive presents itself as a sustainable and viable alternative, although further studies are necessary to validate its application in compliance with Brazilian technical standards.
The Relationship between Economic Growth and the Generation of Urban Solid Waste
This study examined the relationship between economic growth and solid waste generation, aiming to analyze the correlation between economic growth represented by Brazil's Gross Domestic Product (GDP) from 2012 to 2019 and the generation of Urban Solid Waste during the same period. This analysis was based on the theory of Ecological Economics, specifically the second law of thermodynamics, the law of entropy, which states that the economic system extracts resources and low-entropy matter from the environment and returns high-entropy energy and matter, representing environmental degradation and disorder. The main objective of this study was to verify through descriptive statistics if there is a direct correlation between economic growth (GDP) and the generation of Urban Solid Waste (USW) measured in thousand tons per day, representing high entropy. There is a direct relationship between GDP growth and the generation of USW, which raises the research question: how is it possible to control and manage the generation of USW in the face of GDP growth? The methodology involved bibliographic, qualitative, and quantitative research, utilizing statistical data such as Pearson's correlation coefficient. The results indicate a significant correlation between GDP growth and USW generation, demonstrating a consistent increase in USW when there is a peak in GDP growth. This suggests that society tends to consume more disposable products in daily life, contributing to waste generation. The conclusion drawn was that GDP growth has become unsustainable as it fails to preserve natural resources and mitigate waste disposal and environmental damage caused by economic activities.

Institutional logic of sustainability: a study on the performance of individual microentrepreneurs and organizations supporting entrepreneurship
This study sought to understand the performance of individual microentrepreneurs and organizations that support entrepreneurship in relation to sustainability. Specifically, it was analyzed whether the Institutional Logic of Sustainability (ISL) has occurred in the sustainable initiatives practiced by such microentrepreneurs, based on content available on the internet such as reports, videos, and scientific articles. This is a qualitative study in which documentary analysis and content analysis were used. The results showed that individual microentrepreneurs have been active in sustainability initiatives in the search for more sustainable businesses and the existence of LIS in these initiatives was verified. The study is relevant for bringing visibility to this audience of entrepreneurs as well as for indicating their relevance in the focus of public policies aimed at encouraging sustainability in small businesses.

Tourism in rural areas: What method approaches are adopted?
To this end, a systematic review of the literature was carried out from 2017 to 2022, analyzing 49 articles. Three journals in the area were selected for the searches: Tourism Management, Tourism Management Perspectives and Journal of Rural Studies. It was observed that the application of the qualitative approach has occurred more frequently in research on tourism in rural areas. Its adoption occurs due to the fact of understanding a certain phenomenon in greater depth, in an interpretative way, based on the knowledge, experiences and perception of those involved. Considering the journals, adherence to the qualitative approach, followed by the quantitative approach, and mixed methods can be seen. It is noteworthy that the mixed methods approach, although increasing, is still far from being dominant. This systematic review is expected to offer understanding about research approaches not only for authors, who look for gaps to develop new research, but also for reviewers and journal editors who work in the area of rural studies.

Analysis of sustainability in the textile and clothing sector from the context of the municipality of Gaspar (SC)
The textile and clothing sector is economically significant in Brazil, offering thousands of jobs throughout its production chain, as well as in the various activities related to the sector. Considering socio-environmental aspects, the sector stands out negatively, due to its impacts on the environment and working conditions, driven by excessive consumption, especially fast fashion. However, it is a sector with the potential to establish more sustainable standards. Through a bibliographical review, the work aimed to present an overview of the insertion of sustainability in the production chain of the textile and clothing sector, using the municipality of Gaspar (SC) as a reference. It was noticed that there are socio-environmental impacts throughout the sector's production chain, and to deal with them, some organizational structures were created. Considering the panorama of the textile and clothing sector, it was noticed that the municipality of Gaspar (SC) needs greater appropriation of the theme of sustainability and the circular economy, in all its dimensions, by all the actors involved in this arrangement. productive. Understanding the complex relationships in the chain is necessary to promote responsible measures in the management of companies in the sector.

Sustainable Management and Treatment of Explosive Solid Waste: Approaches for Civil and Military Applications
Energetic materials release their chemical energy through slower exothermic reactions, as observed in propellants, or instantaneously, as with explosives. This narrative review provides a comprehensive and holistic perspective on the complex lifecycle of explosive solid waste (E-SW) and related energetic materials. It covers key aspects such as explosive waste research, definition, classification, history, applications, management complexities, environmental and health impacts, disposal methods, and green innovations. While explosives are critical in both civil and military applications, they pose significant environmental and health risks throughout their lifecycle. E-SW management remains an urgent yet underexplored area in scientific literature, especially compared to other explosive-related topics. Traditional disposal methods, like open burning and detonation, result in significant pollution, contaminating soil, water, and air. Despite this, these methods persist due to the lack of safer, economically viable alternatives. Innovative solutions such as biological treatments show promise in mitigating environmental damage, particularly in decontaminating metal residues for recycling. However, challenges in scalability and effectiveness remain. Prioritizing the development of biodegradable energetic materials and designing devices with safer dismantling procedures are essential. The pursuit of green innovations and further research is crucial to refining E-SW management strategies, reducing pollution, and protecting ecosystems and human health.
