Seaweed is a fast-growing biomass source that is currently studied as feedstock for sustainable industrial production in a wide variety of markets. Being composed mostly of polysaccharides, macroalgae can be integrated in biorefineries for obtaining bioproducts via fermentation. Kappaphycus alvarezii has been introduced experimentally to Brazil's south coastline in 1995 and is now cultivated on a large scale to keep up with the high carrageenan demand in various industrial sectors. In this review article, an introduction is given on renewable biomass and environmental issues, focusing especially on third-generation biomass and its promising features and use advantages. Later on, the processing of K. alvarezii for the use of its saccharide portion for fermentative processes is approached. The current state of research conducted alongside challenges and hurdles in K. alvarezii hydrolysate fermentation processes provides insight into future studies needed to make new fermentation processes viable. Next, some fermentation products are discussed, and the metabolism of galactose in microorganisms is also presented to bring to light other possible fermentation products that are not yet, but can be, obtained from K. alvarezii. Finally, a simple and comprehensive scheme for K. alvarezii fermentation biorefinery is presented to demonstrate a generic example for a possible configuration for obtaining valuable bio-products. In the literature, production of ethanol and lactic acid were already reported from K. alvarezii. This review aims to help envision new industrial processes that can be developed for this most valuable macroalga. [ABSTRACT FROM AUTHOR]

In this study, the oils of açaí, passion fruit, pequi, and guava were submitted to physicochemical analysis to investigate their potential application in the food industry. Gas chromatography associated with mass spectroscopy showed that oleic and linoleic acids are mainly responsible for the nutritional quality of açaí, passion fruit, pequi, and guava oils, which exhibited 46.71%, 38.11%, 43.78%, and 35.69% of the former fatty acid, and 18.93%, 47.64%, 20.90%, and 44.72% of the latter, respectively. The atherogenicity index of the oils varied from 0.11 to 0.65, while the thrombogenicity index was 0.93 for açaí, 0.35 for guava, and 0.3 for passion fruit oils, but 1.39 for pequi oil, suggesting that the use of the first three oils may lead to a low incidence of coronary heart disease. Thermogravimetry showed that all tested oils were thermally stable above 180 °C; therefore, they can be considered resistant to cooking and frying temperatures. In general, the results of this study highlight possible applications of these oils in the food industry, either in natura or in typical food production processes. [ABSTRACT FROM AUTHOR]

How and why does legacy news media move from protecting to undermining democracy? Several studies argue that journalism can facilitate and shape democratic backsliding. However, evidence is scarce and, to some extent, limited to the content analysis of news outputs and editorials. The causal mechanisms of an anti-democratic role for the press and how it is operationalised into specific processes of news production remain largely misunderstood. Using 36 semi-structured qualitative interviews and three case studies, this paper analyses journalistic practices and role perceptions in Brazil within a period of constant decline in the quality of democracy (2016-2021). The results show that labour precarity is a crucial driver in journalistic practices capable of damaging democracy, which challenges previous assumptions that media capture is mostly influenced by the political economy of news organisations. This research also indicates that journalists are not homogeneously dominated by the interests of elites and can engage with them on their own terms to advance personal agendas.

Waste treatment and valorization have become crucial for sustainable development towards a circular economy. As an alternative, biochar production is a promising process to convert wastes into a valuable product that presents several potential applications to cope with environmental problems. Biochar in recent years has been the subject of many studies, which have leveraged the number of patents and the industrial interest in this process. Against this background, this overview aimed: (i) to identify the advances in biochar research; (ii) to assess the number of patents on biochar over the years; (iii) to look at the industrial production of biochar worldwide; (iv) to detect the potential for biochar production in Brazil regarding waste biomass availability; and (v) to discuss the potential of biochar in contributing to reach some Sustainable Development Goals (SDGs). The holistic analysis presented here suggests that progress has been made in research, patent development, and industrial implementation of biochar, and that its potential role in achieving certain SDGs is noteworthy. Therefore, this overview can be useful in guiding future research about biochar to improve the knowledge of the different branches in this field. [ABSTRACT FROM AUTHOR]

The modeling and simulation of industrial mineral processing operations are traditionally used for cyclone sizing and optimizations of industrial operations. However, the main models used are based on the total population of particles in the pulp, thus not distinguishing the individual minerals. This article presents the results of an innovative method that investigated the optimization of the metallurgical recovery of P2O5 in the desliming circuit of a phosphate ore processing plant in Brazil. A survey campaign was carried out in the existing industrial circuit, followed by determining the partition curves for the overall particles and specifically for the hydroxyapatite particles. The results were used to calibrate the Narasimha–Mainza cyclone model. From a Base Case determined with reference to the industrial survey, three optimization scenarios were simulated through cyclone geometries and respective operating conditions changes. Simulated scenarios indicated the possibility of P2O5 metallurgical recovery increasing from 9.4% to 12.7% compared to the Base Case. [ABSTRACT FROM AUTHOR]

Controlling particulate matter (PM) emissions to the atmosphere in industrial processes is critical for a safe and healthy environment. Because of its high strength and thermal stability, silicon carbide (SiC) is among the best materials for producing hot gas filters to be coupled to sugarcane bagasse-fired boilers in Brazil and India. In this study, we evaluated the performance of asymmetric SiC-based filters of different features for removing fine PM with particle sizes ranging from 90 to 3000 nm. The collection efficiency of the asymmetric filter made of SiC/mullite support with no pore former, porosity of 31–33 %, and permeability of (0.17–0.30) × 10−11 m2 with a coating thickness of 109–138 μm, effective pore size of 19–26 μm, and effective collector diameter of 64–86 μm was higher than 99 % for PM with size greater than 0.60 μm. The SiC formulation with mullite and pore former also presented promising performance. The resulting pressure drop remained within the range reported for commercial hot gas filters. Over 99 % of the mass of soot and fly ash particles generated during sugarcane bagasse combustion exceeds the MPPS range found for filters, which was between 0.16 and 0.36 μm. Therefore, the SiC asymmetric filters presenting mullite in their formulation are anticipated to meet current international emission standards. [ABSTRACT FROM AUTHOR]

This work evaluates large-scale hydrogen production processes - those capable of providing hydrogen for an eventual automotive hydrogen program in a community and along highways - with the aim to Sidentify which of the production processes of hydrogen is more attractive for an eventual automotive hydrogen program. To perform the research, the MACBETH (Measuring Attractiveness by the Category-Based Assessment Technique) method and the computational code M-MACBETH 3.2.0 are used taking into account multiple criteria. Thus, this work used the computational code M-MACBETH 3.2.0 to evaluate twelve hydrogen production processes and build rankings of attractiveness of hydrogen production processes, considering the following criteria: economic (invested capital and production cost), technical (the purity of the hydrogen produced) and environmental (the amount of energy used to produce 1 kg of hydrogen and the CO2 emissions to produce 1 kg of hydrogen). In the end, three rankings are produced considering three scenarios, which allow to conclude that: if decisions regarding hydrogen are made taking into account that economic and financial aspects have the same weight as sustainability aspects, the more attractive hydrogen plants are those that use the Solar Thermochemical Plants; if decisions are made taking into account that economic and financial aspects are more important than aspects of sustainability, the production process more attractive will be the one that uses the SR technology - Ethanol and Natural Gas Steam Reforming; and that Solar Thermochemical Plants becomes more attractive than all others alternatives when, in decision-making, sustainability environmental aspects prevail over economic and financial aspects. • A multi-criteria analysis was performed to evaluate the most convenient hydrogen production process in Brazil. • A total of twelve processes of hydrogen production were evaluated. • Rankings of attractiveness of the processes were generated considering criteria: economic, technical and environmental. • Solar PV electrolysis is more attractive if sustainability aspects prevail over economic and financial aspects.

Objective: To analyse the purchase of food for school feeding, according to the extent and purpose of industrial processing and variety, exploring the feasibility of achieving the requirements and recommendations of the Brazilian School Feeding Programme, and the variety of unprocessed or minimally processed foods according to the purchase of ultra-processed foods. Design: Secondary data from 2016 from the Accountability Management System of the National Fund for Educational Development, concerning the food items purchased, were used to explore the feasibility of the requirements and recommendations. The foods were grouped according to the NOVA classification system. Variety was assessed by counting different types of unprocessed or minimally processed foods. Setting: Brazil. Participants: 3698 Brazilian municipalities. Results: Energy share from unprocessed or minimally processed foods was 44·1 % while that of ultra-processed foods was 29·9 %. The average of unprocessed or minimally processed food types purchased annually was 33·8 items. Of the municipalities, 35·8 % were within the limit established for the expenditure of funds for the purchase of processed and ultra-processed foods, while 8·7 % followed the recommendation for variety. The proportion of ultra-processed foods did not influence the variety of food items purchased. Conclusions: The results showed the feasibility of achieving the requirements and recommendations and underscored the importance of continued efforts to promote the inclusion of unprocessed or minimally processed foods in the school feeding programme while addressing the challenges associated with expenditure limits of processed and ultra-processed foods and enhancing variety, which is strategic to promote adequate and healthy meals.

The Ilex paraguariensis is a species native to Brazil, Paraguay and Argentine, valued by its positive effects on human health. Mate processing consists of the following stages: pre-drying (rapid drying at high temperature, known as sapeco operation), drying, and milling. In order to verify the current process and to propose future improvements to the mate processing, thermal and mass balance analysis were applied to industrial mate processing units. Results showed that the consumption of energy in sapeco and drying operations exceeds the calorific input necessary for these operations. These results verify the need for a change in the management of temperatures in the sapeco and drying stages of mate processing in order to optimize the consumption of energy, resulting in lower costs, with positive effects on the quality of the mate products.

In Brazil, sucrose-rich broths (cane juice and/or molasses) are used to produce billions of liters of both fuel ethanol and cachaça per year using selected Saccharomyces cerevisiae industrial strains. Considering the important role of feedstock (sugar) prices in the overall process economics, to improve sucrose fermentation the genetic characteristics of a group of eight fuel-ethanol and five cachaça industrial yeasts that tend to dominate the fermentors during the production season were determined by array comparative genomic hybridization. The widespread presence of genes encoding invertase at multiple telomeres has been shown to be a common feature of both baker's and distillers' yeast strains, and is postulated to be an adaptation to sucrose-rich broths. Our results show that only two strains (one fuel-ethanol and one cachaça yeast) have amplification of genes encoding invertase, with high specific activity. The other industrial yeast strains had a single locus (SUC2) in their genome, with different patterns of invertase activity. These results indicate that invertase activity probably does not limit sucrose fermentation during fuel-ethanol and cachaça production by these industrial strains. Using this knowledge, we changed the mode of sucrose metabolism of an industrial strain by avoiding extracellular invertase activity, overexpressing the intracellular invertase, and increasing its transport through the AGT1 permease. This approach allowed the direct consumption of the disaccharide by the cells, without releasing glucose or fructose into the medium, and a 11% higher ethanol production from sucrose by the modified industrial yeast, when compared to its parental strain.

The use of tailings generated during the iron ore beneficiation process has been the subject of several studies aimed at finding economically viable solutions for managing the waste generated by the mining industry. In this context, this study was developed with the purpose of characterizing foundry sands manufactured from the waste material originating from the Andrade Mine in Minas Gerais, Brazil, with the aim of assessing the feasibility of using these sands as molding material for the casting process. Initially, the overall tailing sample underwent size classification to 150 µm, and the retained fraction was separated into two foundry sand samples, named Sand 01 (without additional treatment) and Sand 02 (subjected to magnetic separation). Studies were conducted on the chemical, physical, optical, and mineralogical characteristics of both the overall sample and the obtained sands. The results indicated that both sand samples were classified as medium sands based on the fineness modulus, an essential characteristic of materials used for casting molds. Sand 02, in particular, demonstrated characteristics closer to the standards recommended by the CEMP E-01 standard of ABIFA, highlighting the possibility of using this material as a coproduct of iron ore beneficiation.

Armoring civilian vehicles requires specialized knowledge and experience that many armoring companies lack as they are not direct or indirect suppliers of vehicle manufacturers. This limits their access to automotive quality and manufacturing certifications or detailed vehicle designs, which can result in loss or malfunctioning of automotive components during the armoring process. Therefore, this study aimed to investigate the challenges faced by Brazilian civilian armoring companies and identify opportunities for improvement in their production processes. Qualitative research was conducted using a questionnaire-based survey of eight specialized firms in Brazil, as well as literature related to DFMA, design for manufacturing and assembly, quality, automotive, and ballistic references. The study results include detailed armoring operation steps, qualitative survey reports, and helpful literature references for armoring practitioners to generate a standard armoring procedure for different vehicle models. Following best practices in automotive and armoring procedures collected in the survey responses can standardize and enhance ballistic protection operations while preserving the original vehicle systems' functionalities and warranties. This work provides valuable information for armoring companies to improve their operations and interfaces with automotive systems and follow automotive and ballistic references.

Artificial Intelligence has reached journalism in different phases of the news production process, from the identification of news trends to data processing or the automatic production of texts, among others. Its potential manifests itself especially when there is a large amount of data, something that sections such as sports and economy can offer. Of the two options, in this work we chose sports journalism and, thus, we sought to know and understand how newspapers, radios, TV's and digital native products in Brazil and Portugal have been related to Artificial Intelligence. To achieve the proposed objectives, we sent a survey to the heads of several media in both countries with questions that helped us to realize that editors and managers know the contribution that AI can offer to their newsrooms. Among other results obtained, we highlight that the use of AI in the Brazilian media is more present than in Portugal, but there is a convergence in its uses and in the difficulties for further development: lack of economic resources and low knowledge about the potential of AI. Among the reasons for the use of technology, the objective of making the work of journalists more efficient and saving time in production stand out. It is concluded that Portuguese and Brazilian sports media editors are aware of the potential of AI, but right now economic and professional difficulties are the main adversary to its implementation in newsrooms.

Fast drying (~60 min) is useful for optimizing production processes by increasing productivity and reducing costs and environmental impacts, especially in red ceramic industries in Brazil. However, suitable clays are necessary and, currently, studies focused on the plastic behaviour of clays with compositions suitable for extrusion, especially for fast drying, are scarce. Therefore, in this study, three different clays from the same mineral deposit were studied for producing clay-based structural products via fast drying. The clays were characterized according to their chemical, mineralogical and thermal properties, particle size, cation-exchange capacity, specific surface area and open pore volume distribution. Ten formulations were developed using a simplex-centroid mixture design of experiments and their plasticity index (PI) values were determined. The response surfaces of the formulations were evaluated according to their PI, while the formation characteristics were determined according to their extrusion workability factor values. Formulations F5 (50.0 wt.% yellow clay and 50.0 wt.% green clay) and F8 (66.6 wt.% yellow clay, 16.7 wt.% grey clay and 16.7 wt.% green clay; PI = 15.5-16.6%) displayed optimal extrusion properties, followed by formulations F7 (33.3 wt.% yellow clay, 33.3 wt.% grey clay and 33.3 wt.% green clay) and F10 (16.7 wt.% yellow clay, 16.7 wt.% grey clay and 66.6 wt.% green clay; PI = 13.8-14.2%), which are within acceptable extrusion index values. Thus, the chosen formulations have significant potential for use in the manufacture of fast-drying red ceramics. [ABSTRACT FROM AUTHOR]

Banco da Amazônia S.A. (BASA) was created in 1942 to meet the demand for rubber in the World War II and nowadays it is the main development agent in northern region of Brazil. Over the years, it has expanded from a single product to an inducer of socioeconomic development, by diversifying the Amazon's productive base in a sustainable way. This article intends to show the role of BASA as a financial agent, its main practices and the impact of its financing to promote the development of the Amazon region. To achieve this objective, data were extracted from the FNO's (acronym for North Constitutional Regional Fund) Financing Program Application Plan for the year 2022; Detailed Report on the activities developed and the results obtained for the year 2020; Results and Impacts Report for the year 2021; and Integrated Annual and Sustainability Report for the year 2021." Besides providing funds to regional production activities, the Bank aims to raise the awareness of agents in the productive sectors of the Amazon region, by showing that investing in ecologically sustainable items and cleaner production processes is no longer a luxury, but inherent to business in order to preserve the environment while increase its profits. By reducing negative impacts on the planet, companies create new markets and add value to their brand and products. [ABSTRACT FROM AUTHOR]

In Brazil, textbooks are distributed free of charge by the National Book and Didactic Material Program (PNLD). However, these books have a commercial character at the country level, bringing copies of national and international scale. However, the most current pedagogical theories claim that students feel more motivated in the classroom when they make connections between the syllabus and their daily lives, in addition to learning about what surrounds them, feeling part of that territory, seeking to preserve it. it. Currently there is a deficit of didactic materials that fulfill this role, being necessary to produce them. In view of this, the present work aims to present the construction of two didactic notebooks (one with contents and the other with activities) in the territory of the Geopark Quarta Colônia Aspirante UNESCO, in order to collaborate in the teaching practices and methodologies developed in Geography classes at School Primary, offering subsidies to qualify knowledge in heritage education in schools in the territory. Methodologically, a qualitative-exploratory approach was used, carrying out bibliographical and documentary research, guided by weekly meetings. The results achieved in terms of final products were satisfactory, being structurally organized into 5 units that present, respectively, the general/political characterization of the territory, the municipalities and heraldic elements of each one, the relief, the hydrography and the landscape. Finally, it should be noted that the material is in the process of being revised and will soon be delivered, at least virtually, to the schools that make up the territory of the Geopark Quarta Colônia Aspirante Unesco.

Furniture production is one of the most traditional activities in the transformation industry. In this segment, wood predominates as a raw material, which also undergoes an industrial transformation process to later be destined for furniture producers. In addition, the furniture sector chain has links in the branches of capital goods (machinery and equipment) and intermediate goods (textiles, paints, packaging, parts and metal parts, etc.). The objective of the article is to present an overview of furniture production, emphasizing the analysis of the dynamics of the sector in Brazil from the 2000s. To achieve this objective, bibliographic search is used through the state of the art published about the theme, in addition to data from the main repositories. It is argued that the Brazilian furniture production was raised to a new level of development based on the economic and social policies put into practice in the Lula-Dilma governments. This finding is based on reality data, which are exposed in the text. At the best moment for the sector, the number of formal jobs grew by 4,15% between 2007-13, a very different performance compared to -3,40% between 2014-19 (RAIS, 2019). The value of industrial production grew by 10.23% and -0,15% respectively in the same periods (IBGE, 2018). [ABSTRACT FROM AUTHOR]

This paper develops an approach that articulates methods characterized as soft and hard Operational Research. This approach is known in the literature as Multimethodology, Hybrid Modeling, or Mixing Methods. As a Multi‐Paradigm Hybrid Study, the present research provides an interface between the qualitative and quantitative modeling of the problem addressed. In this way, it facilitates the engagement of managers with analysts in the search for solutions to problems. The applied objective is to improve the performance of production processes at a prosthetics and orthotics factory located in Rio de Janeiro, Brazil. It applies a multimethodology to support evaluation and intervention using knowledge mapping and a discrete‐event simulation model. Lessons learned from integrated workshops enabled the devising of an alternative improvement scenario for orthotics manufacturing. Theoretical results are validated through effective intervention, providing an increase in production capacity and reduction of the manufacturing lead time. This was made possible through the understanding and engagement of stakeholders during the modeling process. [ABSTRACT FROM AUTHOR]

The sociologist and anthropologist Gilberto Freyre (19001987), author of The Masters and the Slaves (1933), and historian Sérgio Buarque de Holanda (1902-1982), author of Roots of Brazil (1936), are considered two of the main interpreters of Brazilian society, having both produced works that continue to impact the understanding of Brazil. According to some, these were the works that "inventedBrazil". In this essay, I seek to analyze these authors' experiences while abroad and the impact this had on the production process of their best-known works. In the case of Gilberto Freyre, I highlight his academic training in the United States, and in the case of Sérgio Buarque de Holanda, his free training in Germany. As this work shows, different academic and cultural experiences abroad led to different interpretations of Brazil. Based on the analysis of their biographies and best-known works, I highlight how some of the main interpretations of Brazilian society were made possible by the particular "intellectual diaspora" in which they participated, and identify some of the key influences permeating their work.

In the Território da Bacia Leiteira – TBL in Alagoas/Brazil, the elaboration of homemade cheeses and the maintenance of the know-how intrinsic to its production process make up the repertoire of territoriality appropriated and reproduced by small family farming. The aim of this article is to analyze the social and cultural dimensions of these foods, whose preservation is attributed to the women, referred to as guardians of the art of cheese making. The methodology was based in bibliographic and field research. At this stage, 51 homemade cheese factories were mapped: 50 units, which house the production of curd cheese, and an establishment that processes macururé cheese. The results of the research denote that the preservation of knowledge inherent to the elaboration of homemade cheeses configures mechanisms of territoriality appropriated by women. The challenges that pose to the maintenance of these activities presuppose the adoption of strategies that, although admit the processes of cultural resignification to agri-food, must be based on the appreciation of tradition and artisanal production.

Currently, one of the world's concerns, including Brazil, is to obtain answers to reduce energy dependence on fossil fuels. Environmental damage and possible scarcity of fossil fuels highlight the generation of clean energy to reduce environmental degradation. In the present article, it is proposed a model to analyze the economic and environmental feasibility of implementing solar photovoltaic systems in an industry. A case study in Brazil was used to test the model. The selected industrial sector chosen for the installation of the photovoltaic system was the parking lot with an estimated area of 187,653 m2. Regarding economic viability, the calculated net present value was $44,730,630.26, the internal rate of return was 14.52% per year, and the payback time was 132 months. The environmental impacts avoided in the use of the photovoltaic solar energy system were analyzed and the amount of carbon dioxide avoided in the atmosphere per kWh generated with the use of this clean energy showed that 25,381 trees would be needed to fix the CO2 that would be emitted into the atmosphere.

SWEET corn , *ANIMAL feeds , *CULTIVARS , *CORN , *ARID regions , *MANUFACTURING processes - Abstract
Maize has multiple functions and can be used for human consumption, animal feed, or in industrial processes. Grain production has made Brazil a world reference. However, few cultivars are available despite the relevance of sweet corn, especially for family farmers. This is similar to baby corn, in which sweet corn or popcorn is used for its production. In the Brazilian semi-arid region, plant and animal production are limited by water deficit in the dry season. Therefore, the production of sweet and baby corn generates income from the commercialization of the ears and roughage production with the whole-plant harvest. This research has aimed to assess the agronomic performance of five cultivars for sweet corn, baby corn, and fodder production in Agreste Meridional, a semi-arid region of Pernambuco, Brazil. Two experiments were carried out in a randomized block design with five treatments (AG 1051, Alagoano, Branquinha, São Luiz, and PV2 Viçosense) and four blocks. The 1st experiment assessed the performance of the cultivars for sweet corn and fodder yield, in which the cultivars AG 1051 and Branquinha had higher yields for ears (21.9 and 20.3 Mg ha-1) and fodder (10.7 and 10.9 Mg DM ha-1), respectively. The 2nd experiment assessed the performance of the cultivars for baby corn and fodder yield, in which the cultivars AG 1051 and PV2 Viçosense obtained the highest yield for ears (3.1 and 2.9 Mg ha-1, respectively); Branquinha had a higher yield for fodder (8.9 Mg DM ha-1). Therefore, these cultivars have desirable characteristics and can be used in intensive or extensive production. [ABSTRACT FROM AUTHOR]

The tomato plant for industrial processing is a vegetable highly relevant in Brazilian agribusiness. Knowledge on the agronomic and scientific production of the culture is highly important for new strategies of culture and trade and for further studies to supplement the deficiencies in the Brazilian production chain. Current analysis retrieved data on the general features of the produce and of tomato hybrids for industrial processing commercialized in Brazil and a survey on the scientific production with regard to the theme. A bibliographic survey was undertaken on the evolution of tomato culture for industrial processing in Brazil. The number of firms which commercialize seeds and the characteristics of hybrids in Brazil were quantified to evaluate the evolution of production. Scopus databases were researched by keywords "industrial tomato processing" for the 1969-2019 period. Brazil is the greatest producer of tomatoes in South America and Goiás is the state with most cultivation, featuring the municipalities of Cristalina, Itaberaí, Morrinhos, Piracanjuba and Vianópolis with the highest production rates. Eleven firms commercialize seeds in Brazil, mostly with international headquarters. Fruits have a mass between 80 and 240 g and culture cycle varies between 90 and 120 days after transplanting. They show resistance mainly to Fusarium spp., Verticilium spp. and Meloidogyne spp. During the last decades, there has been a growth in the literature on tomato culture for industrial processing, with Italy as the country with most publications. Subareas Phytotechnology and Food Science are the most interesting themes for researchers. In Brazil, teaching and research institutes dedicated to such studies lie in the midwestern and southeastern region of the country. [ABSTRACT FROM AUTHOR]

Plant-based protein-production and consumption have been booming recently, requiring novel, greener sources and processes that can make a real contribution to sustainability. Alternatives offered as patties can be found all over the world, promising less environmental and health risks compared to animal-based protein. In this context, a case study on soy-based patties from Brazil is presented, pointing out sustainable aspects of this value chain, from farm to fork, whilst presenting a theoretical discussion on consumer behavior. The implications of extensive land use for soy monoculture and aspects of the soy patty industrial processes, such as use of hexane, lack of information on labels, excess ingredients, and inconclusive data on food additives (such as methylcellulose), as well as integration of these concepts to design new undergraduate Chemistry curricula, are analyzed. Heavy processing in plants to achieve the taste, texture and appearance of meat increases the environmental footprint of vegetarian diets containing these items, disrupting the idea of sustainability that these products come with. Although meat production has a significant environmental impact, plant-based patties demonstrate that less impactful meat substitutes can also have environmental, social and health risks.

Lean production has been more and more applied in systems with various levels of complexity, which tends to create a gap between Lean-as-Imagined (LAI) in design and Lean-as-Done (LAD) in practice. This paper presents a framework for investigating the influence of complexity on that gap. The framework was applied in a nine-month study in a large plant of a transnational auto-parts manufacturer in Brazil. Three main sources of data were used: 21 interviews, around 196 hours of observations, and documents. Twenty-two examples of the gap are presented; each example is analysed in terms of what LAI and LAD look like, lean principles involved, mechanisms by which complexity influences the gap, and practical implications. Findings suggest that resilience arising from the self-organization of employees, which is a manifestation of complexity, plays an important role for the implementation of lean production. In addition, the framework's contribution to leanness assessment is discussed. Four research propositions to be tested in future studies are also presented. [ABSTRACT FROM AUTHOR]

CONTINUOUS improvement process , *NATURAL products , *MANUFACTURING processes , *RAW materials , *DATABASE design , *TECHNOLOGY transfer - Abstract
The commercialization of natural products is growing exponentially in Brazil and, thus, industries need to have increasingly efficient production processes. In view of the industry's demands for process standardization and continuous improvement execution, the objective was to determine actions for the insertion of improvements in the company's production processes. The method is qualitative in nature, with a descriptive and exploratory design. As a research strategy, a case study was used in a natural products company. At the end of the study, it was possible to present proposals for improvement in the stock of finished product, avoiding damage to packaging, as well as changes in product identification, making the space more harmonious and enabling changes in the current layout. Still, it was suggested the implementation of a PCP sector responsible for receiving, processing, raising the demands of raw materials and purchase requests. This way, the employees from the production sector would be responsible only for the production, not needing to segregate orders of products already in stock and without raw material. It was also suggested the application of a supplier control metric with the development of a database, providing an effective improvement in the choice of suppliers. [ABSTRACT FROM AUTHOR]

In Brazil, many anthropologists are encouraged to act for the benefit of minority groups, assuming an activist role in conducting research on and with them. Yet efforts to integrate these dual roles are undermined by the continued separation of scientific knowledge production processes from other scholar activist activities. In this article, I seek to contend this separation by reflecting on my work as a volunteer in medios libres (the "free media"). With this form of activism, I sought to support the Mexican Indigenous social movement Modevite alongside my doctoral research, in a process of double contention. I reflect on the possibilities of rethinking the activism–academia dichotomy in knowledge production and on how we can produce knowledge that is more strategic for the people we engage with.

This work aims to implement and analyze the effect of the Single Minute Exchange of Die (SMED) implementation in the bean packaging operation in a company in east Minas Gerais, Brazil. Design/Methodology/Approach: The research methodology used was action research. Two cycles of action research were conducted; the first to carry out phase one of SMED, and the second to execute phases two and three. Originality/Research gap: There are few studies on the application of Lean Manufacturing tools in agroindustry. Some works present case studies, mainly in the food supply chain aiming to fill this gap. Regarding SMED applied in agribusiness, no work was found. Key statistical results: The implementation of this methodology allowed the reduction of setup time by around 58%, the distance travelled by operators in the process by approximately 50%, in addition to gains in a production capacity of 14%. Practical Implications: It is concluded that the application of the methodology caused an increase in the company's productivity, as it was possible to obtain gains in productive capacity without changing the amount of hours worked or the number of employees involved in the production process. Limitations of the investigation: This methodology was applied only once and the challenges encountered were not documented. [ABSTRACT FROM AUTHOR]

The aim is to assess the insertion of information technology in properties of pecan nut producers of the Western Region in Parana State, in Brazil. Some research gaps in the IT literature and most specifically on the matter of pecan nut production were identified by Fronza et al., (2018), Barrios et al., (2010), among others. These authors state that there is little research on the insertion of IT in the pecan production process. A questionnaire was applied to 21 pecan producers in the West Region of Paraná. Significant difference was tested using Kruskal Wallis in relation to the age of the farmer, working time, property size and use of information technology (IT). The 80/20 principle was used to present the main barriers for farmers in relation to the use of IT. In the PDCA analysis, suggestions for continuous improvement were presented. In the findings, differences in the use of IT in properties of pecan nut producers are statistically significant in variables of property size and working time. The size, working time, number of computers, IT service outsourcing, and quality of data access are significantly and positively correlated. The practical implication is to use the implantation of IT in companies, as a methodological lens to evaluate the scenario of pecan producers of the Western Region in Parana State.

This study evaluated how Eucalyptus physiological disorder (EPD) affects wood quality and pulping performance. Although research advances have been made in forest management and tree improvement programs for eucalypt plantations, some areas of Brazil are still subject to abiotic stress, mainly due to atypical climatic patterns. Tree growth is affected by abiotic stress, and this can change the wood properties, which influence the pulping process. The Eucalyptus trees used in this study were three-and-a-half-year-old hybrid clones. In order to evaluate the impact of physiological growth disorder on the wood, trees were selected with higher and lower levels of symptoms caused by EPD. First, the density, chemical composition, and variables of the pulping process of each of these woods were compared. The higher levels EPD symptoms resulted in poorer wood quality for pulping. To reduce the negative impact of the pulping process, reference woodchip samples from the industrial process were mixed with these wood samples and evaluated again. The results show that EPD negatively affected the wood quality required for pulp production when trees from higher stress conditions formed wood with more extractives (60% greater) and 9% more of lignin content. Thus, the amount of reagent used was increased and the pulp yield decreased. One solution to minimize the problem is to combine the woodchips from higher EPD trees and stands (20%) with non-EPD-affected chips (80%). Thus, it appears that affected wood requires special management attention in the context of pulp production. [ABSTRACT FROM AUTHOR]

Eco-innovations are innovations capable of helping to reduce the environmental impacts of production processes. In this sense, the adoption of models that assess comprehensively, in an integrated manner and in different perspectives, the general performance of these innovations allows managers to guide their decisions. The object of this research is the use of an eco-innovation in the production processes of cassava, where the waste generated is treated by biodigesters. These cassava processing industries are located in southern Brazil, Paraná State, comprising a multiple case study. A literature review was also carried out to propose a set of indicators capable of assessing the overall impact of this eco-innovation in eight lines of action: (1) environmental, (2) social, (3) economic, (4) human resource training, (5) institutional development, (6) introduction of innovation, (7) unwanted occurrences, and (8) characteristics of environmental management. To compile and process the data, the computerized model INOVA-tec System was used. The objective was to employ the INOVA-tec System model as an instrument for evaluating eco-innovative processes in leading companies in its segment, looking for evidence to expand its usability to other realities in the agro-industry. The results show that the technology scenario is favorable to its dissemination; however, the low performance of the indicators together makes it underutilized. [ABSTRACT FROM AUTHOR]

The value of lignocellulose residues for green technologies has been growing, but biomass pretreatment is still an economic challenge. In this case study, a cost analysis of subcritical water pretreatment (SCWP) of sugarcane by‐products for ethanol production was conducted. The proposed industrial scheme is attached to a Brazilian sugarcane mill, which generates a surplus of bagasse. Seven scenarios were simulated to address the prospects of the implementation of the process in the mill. The fermentation of sugarcane bagasse hydrolysate with Scheffersomyces stipitis upgraded the ethanol yield. The fixed capital investment of the industrial process was approximately US$27 million and 35% of this was associated with the SCWP. The highest ethanol yield was obtained for the process operated with hydrolysate from sugarcane bagasse (6740.5 kg ethanol day−1), which is associated with the high hemicellulose content in the bagasse composition compared with straw. The cost difference revealed that the fixed capital investment and utilities were the largest expenses for process implementation and operation. The simulated process reached 5.45 US$ L−1 as the lowest cost of manufacturing. However, this cost is approximately 10‐fold higher than the market price for ethanol in Brazil. In conclusion, the SCWP of sugarcane straw and bagasse demands significant technical improvement before scaling up to the industrial scale for bioethanol production. © 2021 Society of Chemical Industry and John Wiley & Sons, Ltd [ABSTRACT FROM AUTHOR]

This work has been developed in a large steel industry in Brazil, which produces railway and industrial components, and whose aim was to reduce casting defects. Usually, in industrial processes, identifying the causes of defects and their control are relatively complex activities, due to the many variables involved. In this context, the production processes of seven products, involving 38 process variables (inputs and outputs), have been evaluated adopting a new and innovative procedure. Initially, using a Weighted Goal Programming ‐ Multiple Criteria Data Envelopment Analysis (WGP‐MCDEA) model, we identified the most relevant input and output variables, and the studied company validated the results. Next, using the multiple regression technique, empirical functions were constructed for two response variables chosen by the company – number of external cracks and number of internal cracks. Then, to model the real processes adequately, we introduced the occurrence of uncertainty on the coefficients of these functions, considering them as random variables, according to triangular probability functions. Finally, applying the optimizer Optquest, optimization via Monte Carlo simulation (OvMCS) was performed, and with the Ordinary Least Square technique, we obtained the best fit for the two response variables. Specialists from the company validated the proposed procedure. They found that the values of input and output variables obtained by OvMSC, as well as the values of the response variables, belonged to the database available in the ERP system of the company. These results showed that the procedure proposed herein provided feasible and useful solutions to improve the industrial processes under study. [ABSTRACT FROM AUTHOR]

Purpose: This paper aims to evaluate the adoption of sustainable procurement practices adopted by Brazilian manufacturing companies in supplier selection; additionally, it is aimed to understand which of these practices enable a better differentiation of the analysed companies. Design/methodology/approach: A systematic literature review was performed to compose the theoretical base of this research. In addition, a detailed study of ISO 20400 standard was conducted. The guidelines of ISO 20400 were used as a base to structure a questionnaire used in a survey with professionals working in procurement sphere of manufacturing companies in Brazil. The data were analysed via frequency and CRITIC (Criteria Importance Through Intercriteria Correlation) method. Findings: A moderate dispersion in the adoption level of sustainable procurement practices in supplier selection process of the manufacturing companies was observed; in practices associated with social aspects, the dispersion is greater. A negative issue to be highlighted is that almost 20% of analysed companies did not even considered in their supplier selection process if their candidates accomplish philanthropic activities, generate jobs in local community and fulfill the Universal Declaration of Human Rights of United Nations (UN). Those two last practices are the ones with the best capacity to differ the companies in the sample. Originality/value: There are few studies that focuses on understanding the adoption of sustainable procurement practices in manufacturing companies' supplier selection process. The main contribution of this study to the literature is to evidence that social requirements in supplier selection process are considered in a clear and well-structured form only by few Brazilian manufacturing companies. Despite the sample size, companies analysed in this research are prominent organisations in manufacturing sector. Thus, if this situation occurs in these companies, a more critical scenario will be evidenced in other organisations. This study has implication for practice and academy. For companies' managers, information present here can be used to debate the theme in the organisational context and the nine practices and scale can be used to perform a critical analysis of company's practices. For researchers, the information present here can be used as starting point for futures studies. [ABSTRACT FROM AUTHOR]
