WASTEWATER TREATMENT EFFICIENCY IN VERTICAL FLOW CONSTRUCTED WETLANDS USING RECYCLED AGGREGATES
Authors: Zednik Ondrej , Dunajsky Michal Kriska
Published: April 2024

The article discusses the efficiency of vertical subsurface flow filters in wastewater treatment wetlands, where the main filtration layer is composed of recycled aggregates. To determine the efficiency of the vertical filter using modified recycled aggregates, three test columns were created. The first column contained natural gravels, while the second and third columns used masonry (RMA) and concrete aggregates (RCA). The test filters were loaded with wastewater from a combined sewer system, with non-dissolved substances removed through sedimentation and filtration. The wastewater was intermittently applied to the filter bodies. During the testing period, the RMA filter column achieved an efficiency of up to 99.9% for NH4 +�N, 83.9% for COD, and 40.1% for TP. The RCA filter column had an efficiency of 99.6% for NH4 +�N, 77.2% for COD, and 42.3% for TP. These values are comparable to the efficiencies of filter columns filled with natural aggregates (NA). These results suggest there is a potential for RMA or RCA to replace NA. This would lead to the conservation of natural resources and a reduction in the initial cost of vertical filters.

Published: April 2024

The effect of climate change on current life is becoming more visible daily. Our capacity to be resilient to these changes is an act of responsibility for the future. Several directions could serve this purpose. The present study aims to determine the current state of the art in unconventional energy sources. Mainly, the focus will be on biomass. Biopower sources are an element of renewable energy alternatives, along with solar, wind, tide, wave, ocean, and geothermal. The statistics underline an increasing trend of these resource contributions to the total power input. The paper aims to determine the benefits of utilizing biomass as a renewable energy alternative. The key characteristics of such an approach will be examined, emphasizing their advantages and the potential for enhancing performance. There were limitations in accessing valuable information from the field. Through it, biomass-type resources present an increased interest due to their particular property to act in a double sense, unlike the other non-traditional ones. The extent of their application will be ascertained based on the available data.

Published: April 2024

The depletion of fossil fuels is a major concern for the world because of the demand for energy that has increased rapidly with population growth and urbanization. For sustainable development, energy producing industries are trying to find suitable substitutes for petroleum fuel that are environmentally friendly and economically feasible. Biomass ,such as bio-oil and biochar production, could be a possible alternative energy source. Production of biochar and bio-oil from chicken manure(CM) by the pyrolysis process could be a robust approach for organic waste recycling. In this work, experiments were conducted to examine the effect of pyrolysis temperature on the quality of chicken manure biochar (CMB) and to identify the optimal pyrolysis temperature for the conversion of CM into biochar. As the maximum pyrolysis temperature gradually increased from 350 to 650OC, the biochar yield, total nitrogen content in biochar, organic carbon (OC) content, and cation exchange capacity (CEC) of the produced biochar decreased ,while the pH value, ash content and BET surface area of the biochar increased. The generated biochar showed yields of 44.87�61.15% reported to raw material mass, organic carbon of 320�370 g/kg, pH value of 9.4�11.7, BET surface area of 2.65�6.35 m2/g and CEC of 50.21� 31.45 cmolc/kg. The maximum transformation of organic carbon from CM to biochar occurred at 550 OC, however 80.5% of N contained in CM was lost to volatile compounds at this temperature. To produce CMB for use as fertilizer, a temperature value of 350 OC should be selected in pyrolysis process while for environmental applications, 550OC is a suitable temperature value. The obtained results suggest that chicken manure could be used as potential feedstocks for slow pyrolysis process to produce high-value products useful as energy resources.

Published: April 2024

Power grids have been the mainstay of power systems for more than a century, supporting economic activity by bringing power to homes, industry and services. As the transition to green energy advances, the role of electricity will become more important, making power grids even more special to society and economies. The energy sector is going through essential changes such as decarbonization, digitalization, climate change etc. and as a solution, governments, industries and other stakeholders will need to establish new policies, regulations and updated market models for a new system in the future. Therefore, our purpose was to develop a system that can track the sun from sunrise to sunset, which can be placed in a specific location to record and store data about the maximum potential sun that can be produced. The solar tracker is guided by two step-by-step motors, creating horizontal and vertical movement so that the rising sun will fall perpendicular to the solar panel. The two motors are controlled with the mobile phone which stores data about the amount of energy that is produced. A prototype was made using parts from reused materials such as bicycle wheel, concrete mixer crown, computer elements, parts for chairs, etc. The system is independent of electricity, so it can be placed anywhere without being connected to an outlet. The motors and the data controller are powered by the energy produced by the solar panel in the form of a closed circuit. The data is used to estimate whether investments in solar panel systems in a specific area are profitable and can provide information about the energy produced daily, weekly, monthly or annually. The advantage of the project is that we can control it with our mobile phone and all data is automatically stored without losing any information due to its own power supply.
THE ENERGY TRANSITION PATHWAY FOR ALASKA
Authors: Nash Art
Published: April 2024

As the only arctic state in America, Alaska is the least dense in population, while consuming more energy (per capita) than any other state. A quarter of that energy presently is provided for by renewable resources, despite a long standing goal out of the legislature to provide half of the state's domestic energy through renewable energy resources by 2025. Of the non-renewable energy produced in the state, natural gas provides half the energy, primarily for the largest urban area. Most of the state�s crude petroleum production has been shipped outside the state for refining on America�s West Coast, while most domestic coal is low in energy content. Yet several types of capital need to be addressed to shift from nonrenewable to renewable energy sources.

Published: April 2024

Eggshells are one of the widely used by-products in the food processing and manufacturing industries. Due to the increased content of minerals, especially calcium and magnesium and less trace elements (iron, zinc, manganese, copper), chicken eggshell waste can be used in many agricultural activities as a mineral fertilizer, as an additive for improving the physical parameters of the soil, or reducing the accessibility of lead and cadmium from soils polluted with heavy metals, as a substitute for natural calcium carbonate or as a nutritional improver in animal feed. The purpose of this paper was to characterize the eggshell waste resulting from household activities of food preparation and their use for the regeneration of the acid soils contaminated with heavy metals. The objectives of this study was to evaluate the effectiveness of eggshells as a material for blocking lead and cadmium in acidic soils contaminated with heavy metals. The use of eggshells in agricultural soil rehabilitation activities contributes both to increasing soil fertility and can also be an effective way of neutralize eggshell waste from agro-industrial activities. It can be also said that chicken eggshell powder can be recommended both as an organic fertilizer, which increases the mineral intake of plants, and as a soil stabilizer, improving plant health.

Published: April 2024

Disposal of by-products from the processing of plant foods is a major industry concern, but these by-products are also promising sources of compounds with technological or nutritional properties and are now being considered as a possible source of functional compounds. The common bean (Phaseolus vulgaris L.), which contains a high protein content, fiber, and other critical minerals for humans, is one of the most significant pulses in the world. The objective of this work is to exploit the properties of common bean (Phaseolus vulgaris L.) by-products by including them in powder form in new bread products, in order to improve their properties. Empty common bean (Phaseolus vulgaris L.) pods were dried, mild and incorporated with different levels (5%, 10% and 15%) into dough and breads made from wheat white flour. The moisture content decreased in proportion to the amount of wheat flour substituted. Analysis of the bread showed that the addition of empty bean pod powder did not significantly improve the textural profile of the bread. In fact, there was an increase in hardness (1011.26 N/mm2 for the control and 1027.38 N/mm2 for the breads enriched with 15% powder, respectively). The pH and porosity also increased in proportion to the amount of wheat flour substituted. Regarding the sensory analysis, the breads obtained with different proportions of vegetable waste powder additions were liked by several categories of people and were noted with high scores. To conclude, the powders obtained from vegetable by-products can be used as functional compounds and can partially replace the wheat flour added to make bread.

Published: April 2024

The topic of sustainable mobility has been prioritized on the EU�s political agenda, with the goal of lowering CO2 emissions and air pollution. This goal entails the introduction of low-polluting cars, such as those driven by an electric battery (BEV), into the EU car market. The current investigation was guided by the theory of planned behavior (TPB): The three main TPB constructs�attitudes, subjective norm, and perceived behavioral control�as well as the intention to purchase a BEV have been measured. In addition, we were interested to explore the influence of individuals� uncertainty due to the Ukrainian war on the intention to buy a BEV. Future uncertainty related to the war in Ukraine might enhance individuals� concern about economy and energy, thus influencing the intention to buy BEVs. An online survey was conducted, with measures of the TPB main constructs and war-related uncertainty. Results show that attitude, subjective norm, and perceived behavioral control significantly predict the intention to buy BEVs. In addition, future uncertainty due to war in Ukraine has a significant positive indirect effect on participants� intention to buy BEVs via attitude and subjective norm. Theoretical contributions and practical implications of results are discussed in the paper.

Authors: Valujeva Kristine , Grinfelde Inga , Pilecka-Ulcugaceva Jovita
Published: April 2024

Reducing GHG emissions from soil is crucial for mitigating climate change, promoting sustainable agriculture, protecting ecosystems and biodiversity, ensuring food security, and improving public health. The effectiveness of GHG mitigating strategies may vary depending on local conditions, soil type, and agricultural practices. It is recognized that conventional farming practices may lead to increased GHG emissions compared to more sustainable farming systems. Therefore, the aim of this study is to research the GHG emission variability from conventionally managed soil. The soil flux of N2O, CH4 and CO2 was measured in three conventionally managed monitoring sites in the vegetation periods from 2018 to 2022 using a mobile spectrophotometer Picarro G2508. The average N2O emission at monitoring sites ranges from 4.1 to 6.6 g ha-1day-1, the average CO2 emission ranges from 73.8 to 122.3 kg ha-1day-1, but CH4 assimilation ranges from 1.7 to 5.1 g ha-1day-1. Transitioning to sustainable agricultural practices may help to mitigate the GHG emissions from soil while promoting soil health and long-term sustainability.

Authors: Horvath Csaba , Aydemir Cem , Yenidogan Semira
Published: April 2024

Going green ... So many projects to reduce environmental impact start this way and continue with the first task being to eliminate printed communication and go paperless and digital. All this is not driven by thoughtful environmental considerations, but by an aversion to paper-based communication that is wrongly anchored in the social consciousness. The authors draw attention to the misconceptions that people have about paper-based communication, showing that they are untrue and that they are often used to greenwash the digital world, thus distracting attention from the harmful environmental impact of their own processes. At the same time, they present the facts against the myths, citing scientific sources and reports, as well as their own research. They analyse the real environmental impacts of paper-based communication and the extent to which technology processes meet sustainability requirements. The world of print communication (including the modern printing industry) attaches great importance to sustainability. The Gutenberg galaxy has provided the basis for the development of human knowledge and culture for half a millennium and plans to continue to play this role in the future. It aims to meet the requirements of environmental sustainability, the circular economy and to work with the rest of the supply chain to achieve the UN Sustainable Development Goals (SDGs). The authors detail and analyse these processes in their work.

In an era of globalization and interconnections, addressing environmental challenges requires effective communication and collaboration on a global scale. This abstract highlights the critical role that modern languages and translations play in promoting sustainable environmental practices. By facilitating the exchange of knowledge, ideas, and best practices across linguistic and cultural boundaries, modern languages and translation services empower individuals, organizations, and governments to work together toward a more sustainable future. This interdisciplinary approach explores the significance of multilingualism, the challenges of linguistic diversity, and the opportunities for innovation in the quest for a harmonious coexistence between humanity and the environment. The abstract emphasizes the need for the integration of language expertise and translation technologies into environmental sustainability efforts, ultimately leading to more inclusive, informed, and effective solutions to pressing ecological issues. Modern languages and translations enable people from different linguistic backgrounds to collaborate and share insights on sustainable practices, conservation strategies, and policy development. This collaboration is essential for addressing global challenges like climate change, biodiversity loss, and resource management.
THE GOOD, THE BAD AND THE EFFECTIVE ?? TRENDS IN SUSTAINABILITY REPORTING IN NEW ZEALAND LISTED COMPANIES
Authors: Balzarova Michaela , Bell Kathryn
Published: April 2024

This paper examines sustainability reporting trends of 50 NZX-listed companies, focusing on their effectiveness, transparency, and accountability. As sustainability reporting remains largely voluntary, unregulated, and inconsistent, this study investigates the current status quo in ESG/sustainability reporting in New Zealand. As a result, it provides managerial advice on what currently constitutes effective sustainability reporting. This paper of qualitative nature explores reporting practices across five key criteria: report type, adopted reporting frameworks, type of adopted governance within an organisation, type of adopted assurance and trends in social disclosures. The findings point to improvements in the quality of sustainability reporting in New Zealand, however, find that most organisations fall short of international standards. The study underscores the necessity for a balanced disclosure of material issues, suggesting the adoption of the GRI and integrated reporting frameworks need to deliver a comprehensive picture of a company's value creation. Additionally, it offers key recommendations for making sustainability reporting more meaningful. This includes disclosure of both positive and negative impacts, data sources, methodologies, and key assumptions used. Furthermore, it identifies the importance of stakeholder engagement to assess and address organisational material impacts, the necessity to adopt clear measurable sustainability goals, and the use of third-party verification for the enhanced reports� credibility.

Published: April 2024

Global heating is happening at an unprecedented speed. As a result, both human society and natural ecosystems are facing significant challenges. Numerous tools and policies are being implemented both for climate change mitigation and adaptation. Substantial amount of funding has been pledged by international governments and private corporations to support these efforts. One of particularly promising tools that tends to gain popularity for addressing climate change are Nature-based Solutions. These tools can be used for both climate change mitigation and adaptation. Additional benefits provided by the application of Nature-based Solutions include support of biodiversity and associated ecosystem services, which in turn foster well-being of the human society. Implementation of the solutions, however, is challenging and requires stakeholder support, thorough research, multi-stakeholder collaboration and financial resources. Implementation and management of Nature-based Solutions for climate change may take several decades until they reach their full potential. This makes stakeholder engagement and attraction of essential investments particularly problematic. Application of modern technologies can support implementation of the solutions and help overcoming the above listed challenges. However, the use of information technologies in design, management and implementation of the Nature based Solutions tends to be limited, in particular in the Global South, where resource constraints and lack of awareness and/or skills may discourage stakeholders from use of the technologies. Thus, we discuss opportunities for application of modern technologies for implementation of Nature-based Solutions and the ways to lower financial and other barriers to their application.

Published: April 2024

Urtica dioica L. is a multi-functional plant commonly known as stinging nettle, which has been used as wild vegetable for centuries. Stinging nettle is a highly nutritious vegetable due to its increased use in different food products and its health-promoting properties. Nettles are highly adaptable occurring in most common areas from unpolluted to highly polluted areas, along stream banks, farmland and also in highly disturbed areas. In hot areas, they prefer sites in partial shade, but accept to grow also in full sun, mostly in moist soils alongside streams or in drains. U. dioica develops easily while under stressful conditions of drought; reducing light absorption and ensuring carbon assimilation through light energy conversion efficiency. The aim of this study is to evaluate the moisture content and antioxidant properties of nettle plant components (root, leafs and stem). Evaluation of moisture contents, total antioxidant capacity and total polyphenol contents in ethanol nettle extracts is important in regard to the potential applications in various fields, such as environment, medicine and industry (food/feed, cosmetics, textiles etc.). The experimental studies were performed on nettle plants collected from three different counties from the western part of Romania and the obtained results were compared to various literature data. Due to the fact that one of the main characteristics of Urtica dioica L. is the resistance to drought, because of the thin leaves and their cuticle and the low percentage of epidermal cells, the study of evolution of leaves and roots moisture content as well as antioxidant capacity can give important information regarding the influence of climate change on plant development.

Published: April 2024

In the current context, in which the European Union, through various projects, requires the reduction of the consumption of pesticides it is necessary to investigate some different products to control the Phytophthora infestans potato blight, biological ones, that have the role of improving the structure and health of the soil, avoiding contamination of it but also of groundwater with synthetic active substances. Potato production is diminished by the presence of weeds, pathogens and pests. One of the most important phytopathogenic agents is Phytophthora infestans (Mont.) deBary, which produces the disease called mange, an important disease that occurs in all areas where potatoes are grown causing economic losses up to 50%. In general, disease management of this pathogen by biological means is a difficult task, especially when the level of disease pressure is high, together with favorable environmental conditions. The study was performed, in Belint area, Timis county, under the climatic conditions of the year 2022. The test product used in study protocol were Fitocid, Fitohelp, Mycohelp, Viridin and Taegro in various rate of application and an untreated check was also included. The assessments were performed at 3, 7, 14 DAT, assessing the effectiveness of the products in respect of the frequency and intensity of the attack. All five bioproducts reduced the severity of the pathogen compared to the untreated control, the antagonism shown by the Fitocid and Fitohelp products against the fungus Phytophthora infestans was maximum seven days after application.

Published: April 2024

Aphids have grown significantly both in number of species and in number of individuals in populations, especially in green spaces in urban environments. By feeding, they affect the plants in the structure of the ecosystem at the foliar and floral level, therefore it is necessary to manage them so that they are numerically reduced but at the same time to avoid the application of pesticides. Through this work, 2 ways of management were tried for 5 months (April-August): by exploiting existing natural enemies and by using sticky traps. The 4 study sites in western Romania (Timi?oara city) consisted of green spaces composed of various mixtures of ornamental plants, usually shrubs and trees of different species. As a result, 4 aphid species (Macrosiphum rosae, Aphis gossypii, Aphis pomi and Myzus cerasi) were identified whose populations had high values (x= 468.7-1246.5) and which were considered as the target organism in the study. The effectiveness of the most common natural enemies (beetles, syrphids and parasitic wasps) was analyzed and yellow sticky traps were placed for dual-role capture (aphid detection and their immortalization). It was found that both methods are effective, the harmful insects being visibly reduced compared to the initial value. Natural enemies vs. phytophagous aphids had a good effectiveness ratio (1:18.25), while colored sticky traps retained and killed 78% of captured aphids. The management of aphids in the agro-horticultural spaces between people's homes, although it seems difficult to achieve, we consider that it can be done within reasonable limits through non-pheromonal traps and existing natural enemies, somehow keeping the harmful populations under control and not affecting humans and the environment.

Published: April 2024

The continuous rise in global population necessitates the prediction of food resources, among which milk stands out as one of the staples. Dairy farms and processing plants need to know how much milk they will have available to manage their storage and processing capacities efficiently. Overestimating production can lead to wastage, while underestimating can lead to shortages. Knowing the expected milk quantity helps in planning the transportation, processing, and distribution of milk and milk products. This study presents a cutting-edge method for forecasting weekly cow milk production using a multivariate time series approach. Leveraging collected data from IoT devices for environmental variables, genetic data from health diaries, and health metrics alongside traditional temporal data, this research aims to provide a comprehensive model for predicting milk yields. � multivariate time series model SARIMAX was trained, tested and evaluated, focusing on ensuring both accuracy and robustness. The findings demonstrate that by integrating multiple data streams, significant improvements in forecast precision can be achieved. Furthermore, this integrated approach provides insights into the key factors influencing weekly milk production, paving the way for informed strategies in dairy management. The proposed model showcases the potential for scalability across different dairy operations and regions, contributing to the global effort towards food security and sustainable agriculture practices.

Sulfonamides are appropriate ligands for the preparation of coordination compounds with biological activity, as they possess bactericidal, antiviral, antidiabetic, and diuretic properties and some sulfonamide compounds are under clinical evaluation for cancer treatment. Metal complexes provide highly versatile platforms for drug design. Considering the biological potential of the quinoline nucleus, but also of the sulfonamide scaffold (especially antimicrobial), as well as that of the quinoline- sulfonamide combination we have decided to combine the two pharmacophore fragments. And at last, the complexation with divalent metals - M2+ (M2+: Zn2+, Cu2+, Co2+ and Cd2+) will bring complementary biological activity given by the cation with the final goal of achieving improved biological activity and better pharmacokinetic properties. The synthesized molecules were characterized by HRMS and NMR spectroscopy. The compounds were preliminary screened for their antibacterial and antifungal activity and the obtained results are very promising.v

Published: April 2024

Grasslands, some of the most important resources of mountain areas, have been and are subject to changes, both in time and in space, under the action of natural and/or anthropogenic factors. In this context, the research aims, in the first stage, to identify and quantify the areas of grasslands subject to changes, both through surface losses and gains, and in the second stage, to establish the general direction of changes, at regional level. As a case study, the area of the Banat Mountains, from southwest Romania, was selected, a very complex area from a physical-geographical and socio-economic point of view. The analysis of grassland areas and implicitly the changes produced, was made in the GIS environment, based on Corine Land Cover data, over a period of approximately thirty years. As a result of the research, it was found that the areas of grasslands were "mobilized" by adding areas from other categories of use (orchards, lands with natural vegetation and so on), but also by switching to other categories of use, especially in high mountain areas, through afforestation. Also, the study showed important differences in territorial profile, of great importance for local communities and the economy of the mountain area. Monitoring changes in grassland areas is also particularly important in terms of management strategies or sustainable development of mountain areas.
THE USE OF BIOENZYMATIC INDICATORS LIKE PROTEASE AND ASPARAGINASE ENZYMES ON BISCUIT PRODUCTS
Authors: David Ioan , Velciov Ariana , Bujanca Gabriel
Published: April 2024

This article presents the rheological study of protease and asparaginase enzymes on dough obtained from white flour used for biscuits. Using alveographic method and falling number method we were able to determine the rheological characteristics of the dough used for biscuits and monitor the effects in the flour and finished products of protease and asparaginase enzymes taking into account different dosages. The technological process of preparing biscuits and crackers using protease and asparaginase becomes more healthy and efficient due to improvements in dough handling, volume and texture of the biscuits. Proteases catalyze the hydrolysis reaction of the peptide bond in the protein between the amino compound of one amino acid and the carboxyl compound of the next amino acid. This leads to the weakening of the gluten structure in the dough. Asparaginase catalyzes the conversion of asparagine and water to aspartic acid and ammonia. This conversion prevents the formation of acrylamide. The falling number and alveograph tests provide results which show that addition of protease and asparaginase to the dough improves the qualities of the finished product, the biscuits being crispier, more porous (they easily melt in the mouth) and more tender. Proteases increase the viscosity of the dough and decrease its stability and tolerance to kneading.

Published: April 2024

Among the newest and best performing metallic materials are high-entropy alloys, which is why more than five thousand articles related to them have been published in the last decade. However, there are few articles that refer to the brazing behavior of new types of metallic materials. In this publication, the brazed joint between two biocompatible alloy components from the MoNbTaTiZrW0.2 system were performed using an ecological Cu-Ag-Zn alloy as filler material. The optical and SEM microscopy analyzes were performed for highlighting the microstructure of a cross-section of the brazed joint. The mutual dilution effects between the high-entropy alloys and the filler metal were quantified by EDS analyses, as well as the penetration mode of the filler metal through the gap between the parts. The soldering process between two HEA plates was performed without protection, in the atmosphere, using an oxy-gas flame with a neutral character. The analyzed joint between the high-entropy alloys had a good brazing behavior, achieving adequate wetting and adhesion of the Cu-Ag-Zn type brazing alloy on the surfaces of the joined parts. It was found that the chosen brazing alloy is very compatible with the base material, no unwanted intermetallic compounds were formed, the penetration into the capillary interstices between the samples was done correctly, without interruptions or cracks.

Published: April 2024

Europe must avoid losing manufacturing SMEs. However, presenting distinct maturity levels, these companies have a hard time fulfilling the necessary ecological sustainability level. Controversially, despite the intense debate about digital technologies, there is still a need for knowledge in the industrial world about the impact of these technologies to make manufacturing SMEs environmentally friendly. According to data made available by Stone Portuguese Federation, in 2019, the Portuguese Ornamental Stone sector (OS.Pt): (i) exported to 116 countries; (ii) ranked 9th in the World International Stone Trade; (iii); was the second country in the world in international trade per capita; (iv) exports covered imports by 660%; (v) 45% of exports were to countries outside Europe and (vi) had a total turnover of EUR1,230 million. Mainly comprised of small and medium-sized enterprises (SMEs), the OS.Pt sector is relevant for the Portuguese Economy, representing over 16,600 direct jobs, and is one of the main generators of private employment in inland regions has registered an average annual growth rate in turnover of 5.13% over the last ten years and has generated around 500 new jobs from 2016. By using the Portuguese stone sector case study, considering the investment to improve the operations towards digital, a framework was designed and used in five groups of forty stone manufacturing SMEs, each representing a digital level. Through a quantitative methodology based on five years after the investment, depending on the technology used and level of investment in digital technologies, it was found a potential reduction of CO2 emissions between 10.7% and 35.1%.

The consequences of human actions on Earth are becoming increasingly evident, leading us to consider that the �climate collapse has begun�, as the General Secretary of the United Nations (UN) warned at the beginning of September 2023. At less than a decade from 2030, the goals and its targets for sustainable development (SD) in the UN 2030 Agenda are far from being achieved, requiring urgent actions. Their fulfilment is at risk, particularly considering recent events such as the war(s) and the pandemic. Developing individual and collective awareness for action is essential. To this end, it is necessary to develop pro-environmental knowledge and attitudes in all citizens, not just the scholar public, which can translate into behaviours favouring the environment and SD. Based on this framework, quantitative research was developed into the scope of communication workshops in a natural biological park in Portugal. This study aimed to evaluate visitors� knowledge about SD and pro-environmental behaviours (PEB) after participating in two science communication workshops: Night of the Fireflies and Recreation of the Wool Cycle. In both workshops, the activities highlighted sustainable development themes in the scope of species extinction and biodiversity. A questionnaire was applied to 47 visitors (n=47) at the end of the activities. The results indicated that all visitors became familiar with SD, although they evaluated their knowledge as just sufficient. Participants also indicated that reducing waste and using plastic are PEBs that most contribute to SD. Finally, visitors considered that the PEB they would be willing to adopt due to their participation were the preservation of cultural and natural heritage and the non-disruption of fauna and flora during a visit to a park or natural area. Developing workshops enhanced citizens� awareness and reflection on aspects of nature protection and SD.

In 2015, the Food and Agriculture Organization of the United Nations (FAO-UN) declared soil a finite natural resource in the face of anthropogenic use, occupation, and exploitation. The importance of soil for maintaining life and other natural resources must be adequately addressed in the curricula for natural sciences and geography teaching. The National Common Curricular Base � BNCC, defined for elementary education in Brazil, and the Paulista Curriculum, specific for the state of Sao Paulo, imply that full training related to sustainability requires the student to have competencies intrinsic to the socio-environmental values development and decision. Resorting to field and laboratory activities on the soil in the classroom, it was possible to approach geoethics when discussing the valorisation of georesources. The educational actions involving the inseparability between human activity and the impacts on abiotic cycles were simultaneously addressed in line with the curricular recommendations (BNCC and Paulista Curriculum). Thus, using the natural resource soil, students participated in activities involving environmental awareness, water consumption/preservation, air pollution, waste reduction, and sustainable consumption, among others. This work addressed the teaching of the soil as an irreplaceable resource for protecting life and environmental balance in elementary school, resorting to geoethics as an approach that allowed the development of non-cognitive competencies related to the environment, such as reflection, awareness, and argumentation. The meaningful impact on students made it worth highlighting this geoethics approach to increase knowledge and develop competencies.

Climate change has precipitated severe issues such as soil erosion, intense precipitation and extended droughts, impacting not only agricultural sectors but also ordinary citizens globally. Unfortunately, human interventions frequently exacerbate, rather than mitigate, these problems. Our approach emphasizes the application of environmentally friendly blue-green infrastructure, recognized for its potential in mitigating climate change effects and enhancing living conditions for both the local populace and the indigenous fauna and flora in treated areas. This strategy is a recurrent focus of environmental programs and projects within the European Union and worldwide. The main goal of our research is to determine of the impact of blue-green infrastructure on potential development of biodiversity restoration in selected model territories using development prediction based on the latest scientific results from similar studies and the professional statistical software Statgraphic centurion 2018. We conducted an assessment at three designated locations within the Zavar village cadastre. Our analysis, based on a comprehensive dataset and meticulous observations, anticipates a significant augmentation in both macrobiota and microbiota diversity, as well as improvements in the fungal and plant community structure within the specified sites. Our evaluation addresses the alignment of these modifications with the specified criteria and identifies any deviations and intercorrelations between treatments applied and groups of organisms and plants observed. We provide actionable recommendations and results will be applicable for predicting and optimizing effect of any planned blue-green infrastructure on biodiversity in business practice.

Introdução: O envelhecimento populacional é uma tendência mundial, e traz consigo diversos impactos econômicos, sociais, e, principalmente, no âmbito da saúde. De acordo com dados da Pesquisa Nacional por Amostra de Domicílios Contínua do Instituto Brasileiro de Geografia e Estatística (IBGE), a população idosa no Brasil, ou seja, com 60 anos ou mais, subiu para 15,1% em 2022, sendo esse percentual de 11,3% em 2012. Dessa forma, a proposta de elaboração de um plano de negócios de saúde trouxe a oportunidade de simular como seria desenvolver uma instituição para prevenção e promoção de saúde em idosos, contribuindo para que pudéssemos adquirir certa experiência em empreendedorismo. Objetivo: Evidenciar a experiência de acadêmicos do ciclo clínico do curso de Medicina na elaboração de um plano de negócios voltado para a promoção da saúde do idoso. Relato de experiência: Este estudo consiste em um relato de experiência desenvolvido a partir da disciplina de Medicina e Comunidade VIII, do Curso de Graduação em Medicina da Escola Superior de Ciências da Santa Casa de Misericórdia de Vitória (EMESCAM). Elaboramos um plano de negócios de uma clínica para a população idosa que busca um ambiente acolhedor e saudável tendo acesso às mais diversas práticas que auxiliam no bem-estar, como atividades de lazer, exercício físico direcionado, além do desenvolvimento de habilidades artísticas. O nome proposto foi "Academia Integrada da Melhor Idade (AIMI)", localizada no bairro de Jardim Camburi, em Vitória-ES, o horário de funcionamento será das 8:00 às 17:00, estando aberta de segunda-feira à sexta-feira. O Plano da AIMI conta com uma equipe multidisciplinar, composta por educador físico, nutricionista, cozinheiros, terapeuta ocupacional, fisioterapeuta, professores de arte e faxineiros. Conclusão: O projeto destaca a necessidade de promover maiores investimentos na área da saúde, tanto no âmbito público quanto privado, direcionados à população idosa. Além disso, a realização deste trabalho permitiu ao grupo um aprendizado na prática dos desafios de se empreender no Brasil, além de trazer um maior contato com planejamento administrativo, financeiro e gestão de negócios e pessoas, proporcionando a experiência de passar pelo processo criativo e a prática da idealização de um negócio.
