Digital technologies and Industry 4.0 hold the prospect of improving the sustainability performance of manufacturing, but the environmental implications of this transformation are uncertain. To contribute to resolving the environmental impacts of production, Industry 4.0 needs to be guided by sustainable manufacturing principles. This article asserts that we have access to only one functioning example of sustainable production on planet Earth, which is nature, and that Industry 4.0 guided by natural biomimetic principles can advance sustainable production goals. It first contends that industry to date has been guided geomimetic principles—which is the industrial mimicking of physical geologic processes—and that geomimicry is a source of many environmental externalities arising from industrial production. The paper then introduces a series of nature-inspired, biomimetic principles that can be facilitated by the unique capabilities inherent in emerging digital production technologies.

In the face of drastic global climate change, the transition to a green economy is becoming increasingly important and it is understood as an opportunity to redesign and redefine business models, products and services, market approaches, forms of consumption, and production. Thus, this study aims to understand how small and medium-sized enterprises (SMEs) adhere to green innovation activities in the management of their business. To answer this objective, the qualitative approach (case study) was used with recourse to interview three SME owner-managers as data collection. From a content analysis, the results obtained show that green innovation is a focus of concern for managers but its operationalization has not proved easy. So two of the SMEs studied here have only implemented measures to recycle the waste produced by their daily activity, although they consider their transition to a green and sustainable business model to be important. The current macroeconomic scenarios reveal the urgent need for SMEs to change their traditional business models to a more sustainable model that involves their managers’ commitment to sustainable development objectives, supported by the green and circular economy, which requires reduction, reuse, and recycling that, as has been shown, still falls far short of expectations. This means that all business stakeholders must understand the reason for adopting green innovation.

Tourism is being impacted by climate change all around the world. Tourism is now seen as one of the economic sectors least equipped for the risks and opportunities provided by climate change, and it is just now establishing the capacity to advance the knowledge required to teach businesses, communities, and governments about the concerns and potential solutions. As a small coastal island, Prince Edward Island (PEI) on Canada’s Atlantic coast is highly vulnerable to climate change extremes, including coastal erosion, sea-level rise, and flooding. The island’s tourism industry generates substantial revenue for businesses and the government, yet it is highly vulnerable to the climate extremes that impact beach and sea-faring attractions. Limited research has been reported on this topic, and most information on island tourism and how sustainable tourism is achievable is out of date. Here, we present evidence of climate-related impacts and vulnerabilities in tourism within PEI and highlight existing and future adaptation strategies to support sustainability in this sector. Key information gaps are highlighted, and recommendations are proposed to facilitate climate resilience in Prince Edward Island’s tourism sector.

Vertical farming methods are gaining importance in the current era of urbanization and industrialization 5.0. These methods of farming enhance sustainability by consuming less space and reducing carbon emissions and greenhouse gas emissions. The Green Internet of Things (G-IoT) offers greater environmental sustainability by switching to a dormant mode while not in use, thereby consuming less energy. Each farming method has a different effect on the shoot and root growth of the plants. Thus, dedicated farming methods must be identified for each crop according to the type of crop under consideration. This leads to a need to compare and analyze the root as well as shoot growth trends of crops in different cultivation mediums, using different cultivation methods, thereby identifying the most suitable method for the cultivation of the crop. A comparative analysis of barley shoot and root growth in green IoT-embedded hydroponics and substrate cultivation methods has shown that hydroponics exhibits two times more shoot growth than substrate cultivation. Furthermore, the results were verified against the results obtained from the simulator, which confirmed that the hydroponic method of cultivation produced a year-round qualitative product with 17.112 tons of biomass and 8.556 tons of dry yield.

The topic of the article addresses the management of the document management system (DMS), which represents one of the important steps for organizations to speed up the implementation of business processes, achieve better control over documents, and ensure safer operations. When implementing and using DMS, the importance of the organization’s maturity shall not be forgotten, as it gives the organization a framework to evaluate and improve the overall effectiveness and efficiency of the organization’s DMS, which can contribute to better decision-making and increased productivity. On the other hand, sustainable-oriented organizations are likely to show interest in choosing, implementing, and using DMS. In the article, the impact of an organization’s maturity and the role of sustainability on the DMS lifecycle are researched. Results are presented based on a case analysis of Company X. Supporting the case analysis, structured interviews with the project leader on the clients’ and the project leader on the providers’ side have been performed, which shall give a deeper insight into DMS implementation and the importance of sustainability and organizational maturity, resulting in more successful DMS implementation and use.

Nanofluid flow has acquired various interesting dimensions with the advent of several novel approaches to studying thermophysical properties. The present work focuses on a comparative study of clear viscous and nanofluid (EG−Al2O3, EG−Zr, H2O−Al2O3, H2O−Zr) flow in a two-phase inclined channel saturated with a porous medium in the presence of thermal radiation, species diffusion, and viscous and Darcy dissipation effects. The controlling equations of the flow model were solved analytically using the regular perturbation technique. The graphical solutions are used to examine the impacts of physical parameters on the most significant flow features. Surface graphs with distinct entrenched parameters represent heat transfer rates and shear stresses on plates. The resulting heat transfer was enhanced by raising the thermal and solute buoyancy strengths, while thermal radiation had the opposite outcome. This enhancement of temperature was maximum for water–zirconium and minimum for ethylene glycol–aluminum oxide nanofluid. The concentration of the entire fluid medium is reduced by decreased mass diffusivity. The enhancement of temperature and velocity is found to be maximum in the nanofluid region and clear fluid region, respectively. This study is validated with previously published works to demonstrate its effectiveness.

Education has played a central role and has had cross-cutting impact on all aspects of human life. China–Pakistan friendly relations have a long history. They cooperate in many parts of life, especially education, i.e., beneficial for better future education exchanges between countries. This study was conducted on the education systems of China and Pakistan to understand the higher education system through a student questionnaire. This research work aimed to investigate the perceptions of Pakistani and Chinese university students on sustainable development in higher education institutes (HEIs). HEIs and universities perform a unique and vital role in society by acting as intellectuals, entrepreneurs, and problem solvers. This section presents state of the art in sustainable development, the role of sustainable development in higher education, and the students’ perspectives. There were 327 questionnaires out of 400, with 27 incomplete replies being discarded, leaving us with 300 complete surveys. The literature and research theme were used to construct the hypotheses of this study. PLS-SEM, a statistical approach that utilized the partial least squares to model structural equations, was used to evaluate the hypotheses. The analysis must take into consideration all parameters. Smart PLS 3.3.9 was used for PLS-SEM analysis in this study. The results showed that quality assurance and students’ satisfaction were significant factors related to sustainable university development programs. Moreover, there was a good correlation between technological improvements in education institutes, teachers’ capacity-building programs, and student–teacher (learning–teaching) relationships. Pakistani institutions comprised 50% of the study’s participants, while students from Chinese universities comprised the remaining 50%. Among all participants, 9.66 percent of respondents were enrolled in Ph.D. programs, 37.67 percent were enrolled in an MS/M.Phil. programs, and 52.67 percent were undergraduate students. Moreover, this study also indicated that technical improvements and advancements positively correlated with sustainable development programs for Pakistani students.

The knowledge of the sources of the sustainability of the subjective perception of households’ material wellbeing is essential in designing a country’s effective socio-economic policy to increase citizens’ satisfaction. The empirical goal of the study is to check the effectiveness and efficiency of statistical and econometric tools. The cognitive task of the analysis is describing material wellbeing and identifying the sources of satisfaction with life. The methods applied to measure and model emotions of interest include correspondence analysis, hierarchical clustering and panel data models (within estimator variants). The main findings are that Polish households declare a sustainable, increasingly high subjective perception of wellbeing. The author identified possible sources of wellbeing and self-perception sustainability. The main factors constituting the subjective perception of wellbeing are dwelling situation and the possession of durables, along with the absence of drastic differences in the material condition of families.

This study aims to provide a comprehensive framework for understanding citizens’ intentions to engage in environmentally sustainable behavior, thus making cities more sustainable. This article investigates environmentally sustainable behavior by adopting the Theory of Reasoned Action (TRA). Using Partial Least Square Path Modeling (PLS-PM), an analysis of survey data from 224 respondents in Italy revealed the salient role of attitudes, subjective norms, intentions, and urban sustainable policies in urban sustainable behavior. Our findings have important implications for theory and practice in this new area of inquiry.

There is a scarcity of freshwater resources and their quality is deteriorating. As a result, meeting human needs is getting more and more challenging. Additionally, significant health problems are brought on by a shortage of freshwater. Therefore, finding a sustainable alternative technique for producing clean water is necessary. Solar distillation is one of the methods that can be implemented to enhance the overall production of pure water. In this work, a hybrid nanofluid was prepared using a two-step method with cerium oxide (CeO2) nanoparticles and multi-walled carbon nanotubes (MWCNTs) in a ratio of 80:20. The concentrations of hybrid nanofluids investigated were 0.02%, 0.04%, and 0.06%. The surfactant cetyltrimethylammonium bromide (CTAB) was used to keep the hybrid nanofluid stable. The studies were carried out over three days in both conventional and modified stills at a constant depth of 1 cm of hybrid nanofluid. The modified still (MS) achieved a maximum production of 1430 mL compared to the conventional still’s (CS) maximum output of 920 mL. The CPL (Cost per liter) for MS was USD 0.039, and for CS, it was USD 0.045. The levels of TDS in the MS and CS were 96.38% and 92.55% lower than those in saline water. The fluoride ion level of saline water was 0.635 mg/L, whereas the distilled water of MS and CS are 0.339 mg/L and 0.414 mg/L, respectively.

European cities should address the climate change challenges, improving quality of life and reducing costs. They need potential smart and digital approaches. Public health (PH) has recognized climate change as a major challenge. The development of urban policies should be guided by evidence-based PH practices. The environmental health determinants and the climate crisis now represent a clear PH threat. The core of the Smart City is sustainability, and its basic condition is active PH. The inclusion of public health into the pillars of the Smart City concept to contribute toward mitigating PH crises, such as the COVID-19 pandemic, is a framework for action. Design Science Research Methodology (DSRM) is used to elicit a Smart Public Health City (SPHEC) framework. A set of PH and smart city experts participated in the DSRM process, using diabetes as a case study. The European Green Deal served as a blueprint for this transformational change toward a healthier and more sustainable city. The SPHEC framework was defined by elucidating clearly the several dimensions of the PH functions within a digital city, via the identification of a set of digital PH services that are required to support the SPHEC framework. This allows for an assessment of the actual benefits that are obtained with the digital health services, and provides evidence for guiding decision-making. The role of digital PH services emerges from the analysis of the SPHEC framework, through the development of proper digital health services within the smart city, strengthening capacity and resilience in future climate emergencies, and motivating policy makers to take this challenge more seriously.

In this paper, perlite mining and rice production by-products, namely run-of-mine perlite and rice husk ash, are used as fine aggregates in combination with pumice and calcareous aggregates to produce lightweight concrete. Their use is evaluated mainly in terms of the durability of the concrete, by comparing four optimized lightweight concrete mixtures of similar density and strength with a reference one of normal weight. The sorptivity due to capillary sorption, open porosity, chloride migration, penetration resistance, and freeze and thaw response were studied to evaluate the durability of the lightweight concrete. According to the experimental results, the examined mixtures developed an adequate strength in order to be classified into strength classes greater than LC25/28 and, therefore, be used in structural applications. The durability of the mixtures was also sufficient, especially as far as the chlorides’ penetration resistance is concerned, which was found to be up to 39% lower compared to the reference mixture. The sorptivity and open porosity of the LWC mixtures increased due to the porous nature of the lightweight aggregates, and the mixtures were also found to be susceptible to freeze and thaw cycles. Exceptionally, the lightweight concrete mixtures comprising pumice and perlite exhibited a lower sorptivity and resistance to chloride penetration than the standard concrete and a promising tolerance to freezing and thawing. Thus, the optimized combination of pumice and perlite is a sustainable recommendation for structural lightweight concrete production and use, promoting the wider exploitation of natural aggregates with an acceptable compromise on strength and durability.

Understanding the concept of sustainability and its implementation in specific actions is necessary for today’s societies, and part of this responsibility falls on Higher Education Institutions. How these institutions have tried to address this issue has been diverse. To standardize, homogenize, and validate these sustainable practices, a few years ago, the University of Indonesia Green Metric positioned itself as the internationally accepted ranking; however, other rankings have begun to emerge, such as the Times Higher Education Impact Ranking, which also addresses the search for compliance of the SDGs. For a novel or incipient university to establish the politics and actions to fulfill sustainability and SDGs or stay on track may represent a disorienting and challenging task, particularly when these rankings have different origins or criteria. So, this research aimed to review the top ten universities and their actions in the University of Indonesia Green Metric and Times Higher Education Impact Ranking, along with the organizational initiatives in education, to clarify the key measures and actions adopted by universities toward sustainability and their participation in the rankings, to pursue the SDGs related to social and environmental impacts in universities. Additionally, as a case study, we analyzed in detail the actions performed by the Tecnologico de Monterrey (located at the 274th and 100–200th places of the University of Indonesia Green Metric and the Times Higher Education Impact Ranking, respectively) and compared them with those of Top Ten Higher Education Institutions in both rankings. As a result, a summary guide of the actions is suggested to guide higher education institutions in adopting the required level of sustainability development indicated in the rankings.

Situated within the context of ‘Transforming our World: the 2030 Agenda for Sustainable Development’ and the associated 17 Sustainable Development Goals (SDGs), this article explores some current understandings about corporate social responsibility (CSR) and related ethical and sustainable business policies and practices within UK-based global businesses. It also considers the potential lessons for small and medium enterprises (SMEs) based on the approaches of global companies. The research engaged senior CSR managers from UK global brand businesses to discuss their CSR perceptions and practices. To the surprise of researchers, the participants described how they were moving past ‘CSR’ to instead use the SDGs as their framework. The findings suggest that global companies are reframing CSR within the broader concept of sustainability, influenced by the SDGs, and are willing to offer advice to SMEs as part of a broader supply chain collaboration process. While there is emerging literature focusing on the practical implications of the SDGs for global business, there appears to have been less attention to the potential for knowledge sharing between global companies and SMEs linked to the SDGs. Our research asked participants about recommendations for SMEs and these are also discussed in this paper. Our intention is to make a particular contribution to the latter area of inquiry and demonstrate the relevance of the SDGs to business, regardless of size.

The main idea of the present study was to investigate the impact of the ongoing world crisis on the socio-economic issues in Serbia concerning building materials usage and purchase. This research fills in the gaps in the literature and contributes to the comprehension of how the crisis has affected salaries, market pricing, and materials consumption in the building sector. The data are gathered through a questionnaire and analyzed using a statistical methodology (frequencies, descriptive statistics, and Spearman’s correlations). Most of the former studies investigated the surveys conducted on specialists in the field, while this study analyzed the perspectives of random people. Socio-demographic issues are analyzed along with materials consumption before and after the crisis. A special emphasis is given to ecological awareness and novel materials usage. Additionally, it captures a broad shift in the economy and ecological consciousness in a developing country. The majority of respondents are open to using novel building materials and products, but their choice would largely be influenced by cost, the amount of effort involved, and their understanding of the advantages. Statistical approaches revealed that the crisis has a considerable impact on the markets for construction and building supplies, altering consumers’ decisions when purchasing. This contribution lays the groundwork for developing countries in the modern world to improve sustainability and adopt circular thinking. Professionals in Serbia need to have a more eco-aware mindset and enhance how they provide pertinent information to potential clients. This study is limited by the number of respondents. For future mathematical modeling and forecasting, more answerers are needed.

Using energy efficiently is crucial for economic development and sustainability. However, excessive use of fossil fuels impedes sustainable economic growth, and the released emissions have a negative impact on the environment. Still, there is no consensus in the literature as to the side effects or even regarding the determinants used to assess this relationship. As such, this article explores the effects that CO2 (carbon dioxide) emissions and renewable energy consumption have on economic growth, using fixed assets, human capital, research and development, foreign direct investment, labor force, and international trade as controls, on a sample of 27 EU (European Union) countries between 1994 and 2019. Four different methodologies were applied to the sample, namely ordinary least squares, fixed effects, random effects, and the generalized method of moments in first differences, allowing endogeneity to be accounted for. Results show that gross fixed capital, human development, and trade contribute positively to economic growth; however, even though these contributions increase due to renewable energy consumption, that increase occurs at the expense of more CO2 emissions. This expense may be justified by the high dependency on fossil fuels in the EU 27 group. Policy implications are presented for policymakers, namely governments, in light of sustainability and climate change.

The aim of this study was to define a protocol for evaluating university gardens as innovative practice in Education for Sustainability and to apply it to a Latin-American study case, that of the Agroecological Garden in the Faculty of Biology at the Veracruzana University (Mexico). A comparative evaluation was conducted between two different moments (December 2018 and January 2021) based on sustainability indicators that were adapted from the SAEMETH-G methodology, using three levels of increasing complexity. These levels were the selection of sustainability dimensions, the individuation of the components, and the selection of the appropriate indicators. At the beginning of 2021, the selected Agroecological Garden showed high sustainability, with an accumulated score of 84.04 out of a total of 100 points, with the agro-environmental dimension being the best positioned (93.74), followed by the socio-educational (91.99) and the economic-administrative (66.4) domains. A significant robustness at the socio-environmental level was evidenced. However, it is necessary to address the substantial deficiencies evidenced at the economic-administrative level, especially in relation to financing and institutionalization, in order to make this innovative didactic resource sustainable and thus contribute to education for sustainability among university students.

Single-use plastic waste has become a growing concern in daily life. Community leaders are implementing programs to reduce the use of single-use plastic and change consumer behavior. This study, using the social cognitive theory framework for sustainable consumption, examines the reciprocal relationship among the following three factors: personal (green consumer values), environmental (bans and rebate/reward programs), and behavioral (consumer decision-making related to single-use plastic waste). The study surveyed consumers (N = 330) across the United States who watched a video on the effects of single-use plastic waste on health and well-being. The results indicate that states with bans or rebate/reward programs tend to have higher green consumer values and consumers in those states report less use of single-use plastic waste. Education level also has a significant impact on green consumer values and plastic waste usage. The study provides a resource guide for decision makers to implement programs in five areas: (1) Business Resources, (2) Public Policy Resources, (3) Non-Profit Resources, (4) Education Resources, and (5) Personal Resources. The study also suggests potential areas for future research.

We can classify the Hikikomori phenomenon with the classification of “social pathology”: the Hikikomori phenomenon, and its spread in society, appear to be a real danger to the sustainability and resilience of the very society in which it occurs. This is because the social isolation of an individual, especially if young and non-independent, impacts the community of reference in human, economic and psychological terms. Therefore, an analysis that investigates the social aspects of the Hikikomori phenomenon cannot disregard the fact that it can be said to be sustainable in the community of reference within which it occurs. This, without wishing to produce a judgment on the merits of the social pathology, is relevant to assessing the capacity of that community to sustain its presence and spread and the human and social costs required to contain it. The research aims to explore the Hikikomori phenomenon in the context of Southern Italy, considering it as an emerging social vulnerability that impacts very deeply onto the sustainability of a social, economic and community systems such as the Campania region one. The following paper therefore presents empirical work conducted in southern Italy, in the Campania region. The methodology used is Mixed Methods, and the research design is Sequential Exploratory. The respondents were reached through the help of the association Hikikomori Italia.

The availability of sufficient water supply is a challenge many municipalities have faced in recent decades and a challenge that is expected to intensify with time. While several choices remain for selecting alternatives to freshwater sources, water reclamation offers an opportunity for sustainable resource recovery. Nonetheless, tradeoffs exist in the selection of the most sustainable technology for recovering resources from wastewater when long-term impacts are taken into consideration. This article investigates the factors influencing the environmental and economic impacts of resource recovery technologies through the analysis of life cycle environmental and economic impact case studies. Key characteristics were extracted from life cycle assessment and life cycle cost case studies to evaluate the factors influencing the sustainability of the resource recovery systems. The specific design parameters include the type of resources to be recovered, technology utilized, scale of implementation, location, and end users. The design of sustainable resource recovery systems was found to be largely driven by scale, location (e.g., as it pertains to the energy mix and water quality restrictions), and the scope of the system considered. From this analysis, a decision framework for resource recovery-oriented wastewater management was developed and then applied to an existing case study to demonstrate its usability.

The resilience of industry has caught much attention since the outbreak of the COVID-19 pandemic. Most of the literature argues that spatial concentration is beneficial to industrial development, but few reports discuss its impact on industrial survival from a long-term perspective, namely resilience. Therefore, this study tries to answer whether spatial patterns impact the long-term survival performance of the industry through investigating the longevity of production sites. We take the semiconductor industry in the Hsinchu area, Taiwan as a case study and hypothesize that the survival period of production sites in clustered areas is longer than that in non-clustered areas. After conducting the research, it was found that the survival period of production sites in clustered areas is not always longer than non-clustered areas. Our results show that only larger clusters and those with higher degrees of clustering might have advantages toward longer survival, rather than the number of average-sized clusters. Our research pioneers in the field of sustainability by bridging spatial studies and industrial resilience theories. As it explores the resilience of an influential industry in the world, its outputs provide new suggestions for future industrial planning, resource distribution and regional development.

Media discourse surrounding fashion and sustainability tends to be negative, emphasising the problems that exist across the various stages of the lifecycle of a garment. Although consumers are increasingly aware of at least some of the issues surrounding fashion and the environment, research suggests that the scale and complexity of the problem causes them to feel detached and uncertain about how to adapt their own behaviour in response. This research positions Instagram as a digital media platform through which sustainable fashion is communicated and experienced through augmented fashion content. Instagram is recognised for its significant impact on visual culture, particularly within aesthetic sectors such as fashion. Recent research reveals that users have begun engaging in more serious subjects and debates on Instagram, including political, social, and environmental issues. This has brought about opportunities for new voices who are championing sustainable fashion in its variety of manifestations. An open qualitative analysis was carried out using the hashtag #SustainableFashion to uncover themes relating to the types of content, stakeholders, and mechanisms that are being used to augment sustainable fashion on Instagram. The findings reveal a positive community of content creators—including vintage enthusiasts, designers, makers and brands—who are using the hashtag regularly to share proactive content in the form of specific, targeted messages around sustainable fashion solutions. The aim was to uncover the discussions that are taking place right now and provide grounding for future work in this area.

This qualitative study investigated the gaps that hinder fruit and vegetable waste reduction in small distributors serving the last miles of the food chain. Fifteen Brazilian distributors operating far from the producers were analyzed. The findings contribute to the literature by showing several research gaps. The surplus in farmer planting increases waste generation at the level of distributors. We should know how to collect and process the relevant data to forecast the demand of each small farmer or distributor (e.g., tendencies in market demands or other farmers’ planting plans). Sectoral entities should use these data to help actors define how much to plant or buy. The acceptance of waste by farmers and distributors has a financial reason. Changing such acceptance requires the demonstration of financial gain that a more sustainable approach may have. We need to know how to calculate the economic gains and losses related to waste reduction throughout the chain (before developing useful mitigators). We should also know how to induce entrepreneurs to invest in better resources or practices in transportation, handling, packaging, and storage. Selling items before their decline avoids waste. We need to know how to improve small actors’ gains to increase sales of such products.

The German federal state of Baden-Wuerttemberg with its regional capital Stuttgart is a major field for the mobility transition in Europe. As one of seven living labs in the state, MobiQ—Sustainable Mobility through Sharing in the Neighborhood follows a civil society, non-commercial approach. Utilizing the research design of living labs, research and practice work hand in hand to promote citizen participation in co-designing and co-producing neighborhood-based, and developing shared mobility solutions. The spatial focus is on three locations: A 10,500-inhabitant post-war settlement on the outskirts of Stuttgart (Stuttgart-Rot), a city-neighborhood with about 6000 inhabitants (Geislingen an der Steige) and a rural municipality of approximately 3000 inhabitants (Waldburg). In this article, we propose how theoretical considerations of the sustainability transitions of mobility systems can be deployed on the ground. Through this study, we offer first-hand insights into living lab experiences and inspire scholars worldwide to harness the networks of civic actors in order to contribute to a cultural change in mobility practice.

Due to the lack of effective impact assessment, urban renewal in China is facing many challenges and dilemmas. Residents’ perceptions are important for the sustainability of urban renewal. This study evaluated the impacts of urban renewal on the economic, social, and environmental sustainability of a neighborhood via a case study of Banan, Chongqing, China. According to the analysis of the questionnaires and in-depth interviews and with local residents, Banan’s urban renewal led to both positive and negative impacts. This study proposed strategic approaches to realizing sustainable neighborhood during urban renewal in China according to impacts. Based on the analysis, strategies for creating sustainable neighborhoods during urban renewal were developed, including balancing of economic, social, and environmental interests, satisfying residents’ needs, and enhancing innovation. The impact of urban renewal in Banan was evaluated based on the economic, social, and environmental sustainability of a neighborhood, and the findings will be useful for policy makers and researchers engaged in sustainable urban renewal to refine their strategy.

Pursuing sustainability in the production inventory model has motivated researchers to reconsider carbon emission costs. In this study, we develop an economic production quantity (EPQ) inventory model to consider greenhouse gas and wastewater emission costs. This study aims to optimize the production quantity, the total costs per production cycle, and the waste emissions. To validate and test the model, data from a pulp and paper mill industry was used. The effectiveness of the model was determined by comparing the costs generated under three (3) scenarios: (1) an EPQ model that considers the costs of greenhouse gas (GHG) emissions; (2) an EPQ model considering shortages; and (3) a multiproduct EPQ model considering shortages. Our proposed sustainable EPQ models can provide decision-makers with insights to visualize how certain factors affect the manufacturing system. Future research can be conducted to consider the product life cycle as well as deteriorating items.

This article analyzes consumer, local producer, and retailer green orientation regarding local food production and consumption in an urban food market context. This approach extends previous research, mainly focused on green orientation of consumers, by including a broader analysis of the perceptions of different relevant stakeholders. For this purpose, an empirical study was carried out in the context of a local urban market of a medium-sized city through the application of a survey to producers, retailers, and consumers, which included a green orientation scale. Results showed that local consumers and local retailers have a similar high level of green orientation, while local producers are less green-oriented. These conclusions highlight the importance of the green “values” in local communities and the need to reinforce marketing efforts and specific training programs to different stakeholders, namely local producers focused on sustainability. info:eu-repo/semantics/publishedVersion

Biomass is a promising form of clean energy that could be utilized worldwide for huge household demand. As the world is constantly fighting climate change and carbon emissions, the adoption of biofuels for households minimizes the ill effects on the ecosystem from households. A recent report from IndiaSpend shows that Indian households bring approximately 3.78 tonnes/capita of carbon, which includes electricity, consumables, and food sources. To bring a balance between utilization demand and ecofriendliness within the household, biomass is an attractive option. Location for producing biomass is a crucial decision problem as it involves multiple criteria that are competing and conflicting with one another. Previous studies on location selection for biomass cannot promptly model uncertainty and consider hesitation and interactions of experts and criteria. To handle these issues, a novel integrated decision approach is put forward. Initially, a generalized orthopedic structure is adapted to model uncertainty from three dimensions. Further, the weights of experts and criteria are determined via variance measure and the CRITIC method. A ranking procedure is put forward with combined compromise solution formulation for rational selection of biomass production location. The usefulness of the developed framework is testified by using a case example and comparison with extant approaches, revealing the superiorities and limitations of the framework.

The increase in the world’s population is driving consumption, leading to the rapid destruction of natural resources and thus raising concerns about the future state of resources. Agriculture and livestock activities, which can be considered under the heading of food, are one of the most significant factors having effects on sustainability. Animal welfare and ethical food selection have become important issues along with sustainability as people’s awareness has increased. As restaurants are an important part of the food industry, chefs have the power to influence sustainability and ethical food choices and set trends with the choices they make. In this respect, it is important to predict the sustainable and ethical food preferences of gastronomy and culinary arts (GCA) undergraduate program students who have the potential to become the chefs of the future, and to evaluate to what extent they regard chefs as responsible for these issues. In this study, the data obtained from GCA undergraduate students were analysed with the decision tree method using lavaan and rpart packages in the R program. The main objectives of this research are to determine the importance of the independent variables in the decision tree classification and the effects of these independent variables. The analysis suggests that the most important factor in the decision tree classification of the independent variables is the attitude towards sustainable food choice. It is concluded that the independent variables are effective in classifying students as high and low in terms of behavioural intention. It is also seen that attitude towards sustainable food choice is more effective in predicting whether behavioural intention is high or low.

Promoting the implementation of education for sustainable development (ESD) in schools is necessary to educate future generations about sustainability. In cases where ESD is integrated into science lessons or ESD has to be taught by science teachers, science teachers have to integrate ESD teaching competencies with their science teaching competencies. The absence of an instrument to assess science teacher competencies to teach ESD makes it difficult for schools to assign the right science teacher to teach ESD or to support science teachers to integrate ESD into their lessons. This study aims to develop an instrument for measuring science teacher competencies to teach ESD. The instrument was developed by combining frameworks of science teacher competencies and ESD teacher competencies issued by several countries and ESD teacher competencies proposed by Okayama University ESD Promotion Center. A four-scale questionnaire comprising 96 statements was developed to assess seven competencies, i.e., content knowledge, content pedagogy, inquiry, professional practice, professional development, assessment and evaluation, and attitude. The instrument was tested on 234 science teachers nationwide, consisting of 166 females and 68 males from different schools, teaching years, and educational levels. The results show that the Cronbach’s alpha of the instrument is 0.99 (very good category), person reliability 0.96 (good category), and item reliability 0.67 (fairly good category). Based on explanatory and confirmatory factor analysis, six competency dimensions are identified. The score of explanatory factor analysis based on Kaiser–Meyer–Olkin (KMO) was 0.966 and the significance on Bartlett’s test of sphericity was 0.00. This means that there are significant correlations among the items. This suggests that the instrument is suitable to identify science teachers’ competencies as indicators of their readiness to teach ESD.

Determining quantitative sustainable development metrics can be difficult and requires a high effort in manual data acquisition on an institutional level, like the Word Bank or the United Nations, without adequately reflecting reality. To overcome the lack of a transparent and scalable method, which links local actions to global sustainability metrics, the Sustainability Mirror connects the Sustainable Development Goals (SDGs) with publicly and locally available data to proxy SDG metrics. By applying the approach to Germany, we calculated eight SDG metrics on a regional level. Comparing our results to two German cities, we show that the Sustainability Mirror reflects economic and ecological sustainability measures. Furthermore, we demonstrate the mirror’s scalability and spatial resolution by applying the method to each German county. Presenting a proof-of-concept, we show that proxy data can link local and global sustainability metrics. However, further research should include more social sustainability topics. Finally, we are sure our approach and its implementations can contribute to a continuous assessment of spatial and temporal spreads and changes in SDG metrics.

Environmental sustainability appraisal of adsorption for exclusion of the malachite green toxic dye was the center of attention in this work. The influenced goals were to analyze the consequences of novel composites fabricated by sodium alginate with guar gum and birm (SA@GG@B composites) by ion gelation. This work not only explains the feasibility of the sorbent and its application for the removal of dye stuff but also proclaimed various effects of different parameters affecting the removal efficiency. Adsorption processes were carried out in the batch process. The composite was characterized by SEM, which revealed that the irregular surface of composites has pores present for high adsorption, FTIR (for functional groups detection) reveals the presence of –OH group which provides attachment sites for dye, and BET (surface analysis) with a surface area of 5.01 m2/g shows that it has a wide surface area for greater adsorption process. Adsorption was performed on synthetic composites by varying different parameters like contact time, the concentration of sorbent and sorbate, and pH. Maximum adsorption was achieved (92.7%) at 100 ppm initial concentration, 120 min interaction time, and pH 9. Adsorption isotherms (Freundlich, Langmuir, Dubnin, and Elvoich isotherm) were applied in this work and evaluated the adsorption phenomenon and nature of adsorption. Freundlich adsorption capacity KF (9.45) reveals effective adsorption of dye by the proposed adsorbent. The kinetics models show that it was better with the pseudo-second-order reaction. Effective removal of malachite green by synthesized composites reveals their importance for the industrial water purification from hazardous dyes.

Traffic congestion has become a growing concern in cities, with both economic and environmental impacts on both individuals and the logistics industry. Therefore, a model of freight distribution in urban areas considering economic and environmental objectives needs to be established to alleviate the consequences. In this paper, a multi-stage heuristic algorithm is designed for solving the route planning based on time-dependent arc travel durations. The algorithm includes a savings method, a modified tabu search heuristic and a cycle transforming optimization (CTO) algorithm. Benchmark instances and the case of Jingdong, one of the largest e-commerce platforms in China, have been adopted to verify the accuracy and feasibility of the model and algorithm. Results of the performance test reveal that the designed algorithm is suitable for addressing large-scale instances. Based on the single objective models, two objectives referring to economical-related and environmental-related factors are considered in the proposed sustainability oriented bi-objective model, and a modified solution framework using a multi-objective decision making method with a relaxation coefficient which is designed for addressing the bi-objective model. Finally, the time-dependent arc travel durations based on real-time traffic information have been incorporated into the optimization algorithms, simulation of distribution process and dynamic route updating strategy, which can reduce costs and route-associated emissions of logistics companies.

With the rapid development of the global digital knowledge economy, educational activities are facing more challenges. Sustainable development education aims to cultivate students’ thinking ability to better integrate with the contemporary world view, so classroom practice should involve innovative teaching and learning. The goal of sustainable development education is to cultivate talents with high-level thinking and sustainable development abilities. The concept of deep learning emphasizes mobilizing students’ internal motivation, focusing on problem-solving ability, improving students’ critical thinking level, and developing students’ lifelong learning ability. The concept of deep learning has evolved with the times. The introduction of the concept of deep learning in teaching can enhance students’ understanding of the nature of knowledge, cultivate students’ high-level thinking, and enable students to achieve better learning results. Integrating the concept of deep learning into teaching has extremely important significance and value for sustainable development education. It has become a hot topic in the world to comprehensively analyze the research status of deep learning and explore how deep learning can help education achieve sustainable development. In this study, CiteSpace (6.1.R2) visualization analysis software was used to visualize and quantitatively analyze the literature on deep learning in the Social Science Citation Index (SSCI). The visualized analysis is conducted on the annual publication amount, authors, institutions, countries, keywords, and high-frequency cited words of deep learning, to obtain the basic information, development status, hot spots, and evolution trends of deep learning research. The results show that the annual publication volume of deep learning is on the rise; deep learning research has entered a rapid growth stage since 2007; the United States has published the most papers and is the center of the global deep learning research collaboration network; the countries involved in the study were often interconnected, but the institutions and authors were relatively dispersed; research in the field of deep learning mainly focuses on concept exploration, influencing factors, implementation strategies and effectiveness of deep learning; learning method, learning strategy, curriculum design, interactive learning environment are the high-frequency keywords of deep learning research. It can be seen that deep learning research has the characteristics of transnationality, multidisciplinary nature and multi-perspective. In addition, this paper systematically analyzes the latest progress in global deep learning research and objectively predicts that using intelligent technology to design appropriate teaching and learning scenarios and evaluation methods may become the future development trend of deep learning. The research results of this paper will help readers to have a comprehensive understanding of deep learning research, provide deeper and more targeted resources for integrating deep learning concepts into teaching, and promote better sustainable development of education.

In recent years, the performance of the construction industry has highlighted the increased need for better resource efficiency, improved productivity, less waste, and increased value through sustainable construction practices. The core concept of sustainable construction is to maximize value and minimize harm by achieving a balance between social, economic, technical, and environmental aspects, commonly known as the pillars of sustainability. The decision regarding which structural material to select for any construction project is traditionally made based on technical and economic considerations with little or no attention paid to social and environmental aspects. Furthermore, the majority of the available literature on the subject considered three sustainability pillars (i.e., environmental, social, and economic), ignoring the influence of technical aspects for overall sustainability assessment. Industry experts have also noted an unfulfilled need for a multi-criteria decision-making (MCDM) technique that can integrate all stakeholders’ (project owner, designer, and constructor) opinions into the selection process. Hence, this research developed a decision support system (DSS) involving MCDM techniques to aid in selecting the most sustainable structural material, considering the four pillars of sustainability in the integrated project delivery (IPD) framework. A hybrid MCDM method combining AHP, TOPSIS, and VIKOR in a fuzzy environment was used to develop the DSS. A hypothetical eight-story building was considered for a case study to validate the developed DSS. The result shows that user preferences highly govern the final ranking of the alternative options of structural materials. Timber was chosen as the most sustainable option once the stakeholders assigned balanced importance to all factors of sustainable construction practices. The developed DSS was designed to be generic, can be used by any group of industry practitioners, and is expected to enhance objectivity and consistency of the decision-making process as a step towards achieving sustainable construction.

COVID-19 has had devastating effects worldwide, and vaccines have become the most efficient solution to address the current pandemic situation thus far. After COVID-19 vaccines had been developed, discussions of the various countries’ equality of access gained traction, with patents and pricing forming a significant part of this discourse. Therefore, this study investigates the impact of patents and prices on the accessibility of COVID-19 vaccines in the developing world, using semi-structured interviews with subject-matter experts in this area of focus. Our analysis of these interviews highlights the fact that patents and prices are not the major barriers to accessibility for medical treatments, both generally and specifically in terms of COVID-19; rather, these barriers relate to the lack of local production capacity, technology transfer, infrastructure, local regulations, and supply-chain competencies. These results suggest that rather than focusing on patents and prices, governments should invest more time in improving technology transfer and using compulsory licenses as a negotiation tool. Moreover, the results show that the pricing strategies applied by companies could have different impacts on access, as could accessibility programs such as COVAX.

One of the significant factors in the sustainability of education is the development of inclusive education. An inclusive educational space implies openness and accessibility of education for students, regardless of their educational needs. Inclusive education also means a partnership between students and teachers. A teacher is a living person whose socio-emotional skills and professional abilities are the basis for the sustainability of education and student development. This article is devoted to studying teachers’ competence and psychological readiness at schools and higher educational institutions to work with students with special educational needs. This article includes the results of a sociological study conducted in September 2022 and is devoted to the readiness of schoolteachers and university professors for inclusive education (N = 125). The general statistical calculation was carried out based on information processing using the Vortex program version 10.0. Universities and schools are located in large administrative centers of Russian regions with a population of about a million. The relevance of this study is due to the relationship of sustainability with the ideas of inclusive education, manifested in its goal of achieving students’ educational levels established by the state and the humanistic concept of equality of opportunity in the process of professional implementation and self-determination of the individual.

Former industrial areas in Europe are being redeveloped into residential and recreational spaces, often including sustainability initiatives. This study explores how the co-governance and management of a productive urban open space contributes to sustainable transformations, and aims to identify the opportunities and challenges that multi-actor design teams face when co-designing sustainable solutions. To achieve this goal, the landscape design process in Klosterøya urban park in Skien municipality, Norway, a privately owned yet publicly regulated park, is used as a case study in co-governance and analysed using the theoretical combined governance and management model developed. Data were collected through the observations of project meetings, document analysis and semi-structured interviews with the multi-actor design team. The results indicated that the working method, through co-creation, produced opportunities for sustainable urban agriculture, enhanced biodiversity, testbeds and water and resource circularities in the landscape, while ensuring a learning process and users’ involvement. Willingness to invest due to the lack of technical knowledge and soil contamination are revealed as key challenges. Conclusions emphasise the significance of co-creative landscape practices for productive urban open spaces and sustainable urban transformations, providing insights for an informed analysis of co-governance cases through the combined governance and management model.

Waste generated from electric and electronic equipment (WEEE) is increasing rapidly due to the high demand for appliances, rapid product obsolescence, coupled with rapid economic growth, urbanization and technology advancement. Setting up a proper WEEE management system, which ensures better collection, treatment, recycling and control of transboundary movement of waste is crucial to increasing resource efficiency, improving sustainable production, use and consumption, and promoting the circular economy in Jordan. However, this system requires proper assessment of WEEE generation rates and reliable figures. Estimation of historical and future electric and electronic equipment put on market (EEE POM) and WEEE generation rates in Jordan have been achieved using the population balance model (PBM), logistic growth model (LGM) and Weibull distribution from 2000 to 2050. It is expected that the total disposal of appliances will reach about 1.6 million units (53 kt) in 2022, double this figure by 2044 and hit around 5 million units (175 kt) in 2050, with increasing WEEE generation rates. This is combined with the changing composition of WEEE with time. Thus, a rapid increase of WEEE in the near future is expected; this increase requires close monitoring and immediate response to tackle this hazardous waste.

Biocultural approaches to restoration, which recognize the unique ways of understanding of socioecological challenges by Indigenous and local communities, have gained traction in recent decades. Yet, less attention has focused on biocultural opportunities where there is no Indigenous population or traditional knowledge to draw upon. This ethnographic study inductively assesses data gathered from interviews with farm owners on Isabela Island in the Galápagos Islands, where human presence is a function of recent migration. These interviews, corroborated with archival information and participant observation, center on farmer attitudes regarding restoration of Scalesia cordata, a highly endangered plant species, endemic to Isabela. The resulting analysis identified four themes of overlap with the biocultural restoration literature: cultural keystone species, sense of place, informational pathways, and recognition of socio-ecological feedback loops. Findings indicate that Scalesia remains a valued cultural keystone species providing tangible and intangible benefits to local residents, and its survival serves as a metaphor for farmers’ own wellbeing. Thus, even locations where place-based knowledge by a native population is not evident, critical biocultural elements exist that can be integrated into restoration efforts. Farmers also exhibited clear connections between restoration and tourism in Galápagos, paving the way for the application of biocultural theory to the analysis of tourism-supported restoration efforts elsewhere.
