Carwash wastewater (CWW) contains grease, oil, hydrocarbon residues, heavy metals, and surfactants, posing severe impacts to the environment and human health. Accordingly, various physical, chemical, and biological processes for CWW treatment have been demonstrated in recent research. In this study, a bibliometric approach was performed to comprehensively illustrate the recent progress, current direction, and future perspectives of CWW-related research. A keyword co-occurrence network was used to represent the results of the bibliometric analysis and to show the major pollutants in CWW effluents and the common systems for treating CWW via coagulation/flocculation, electrochemical, oxidation, membrane, adsorption, biological, and hybrid methods. An integrated anaerobic digestion/oxidation process has been reported to degrade CWW-associated pollutants and help develop an energy-efficient approach for waste management. The results demonstrated that the treatment of CWW has several benefits relevant to sustainable development, viz., good health and well-being, protection of life below water, bioenergy generation, and community awareness and acceptance towards wastewater reuse. Hence, these benefits could assist in meeting the environmental, economic, and social sustainable development goals (SDGs). These study outputs can encourage policymakers and stakeholders in implementing sensible regulations that control water usage and treatment in car sharing and personal vehicle services to either directly or indirectly adopt the agenda 2030 with its seventeen SDGs.

This study aimed to investigate the relationships among mindfulness, self-compassion, and subjective well-being among employees. The questionnaire research method was used to collect data in this study, and the subjects included employees of Carrefour, an international business in Taiwan. A total of 629 valid questionnaires were used to evaluate the overall structure and analyze the mediating effect with the SPSS 21.0 statistical software. The results showed that mindfulness was positively related to subjective well-being, mindfulness was positively related to self-compassion, and self-compassion was positively related to subjective well-being. It was also found that self-compassion partially mediated the relationship between mindfulness and subjective well-being. Full article

Sustainable mental health and wellbeing (MHW), as addressed under SDG3, is crucial for achieving sustainable development, notably for sustainable SMEs growth. MWH is specifically interlinked with SDGs 8, 9 and 11: Economic growth and prosperity, sustainable communities, innovation, and jobs. Studies show over 200 million workdays are lost due to poor MHW each year, referring to the global cost of $1 trillion/year in lost productivity and it is increasing every year. Poor workplace MWH is almost an epidemic after COVID-19. It will be a significant challenge for a long time, in particular for SMEs which are hit hardest by the pandemic, as MHW problems have been shown to be a COVID side effect among 1:5 people. Despite the multifactorial aetiology of MHW (individual, social, environmental, and organizational), interventions for workplace MHW mostly refer to ‘one size fits all’ and top-down solutions, primarily asking for the commitment and behaviour change of employees; that has shown to be ineffective. The main assumption underlying the present work is the need for a proactive and tailored MHW frameworks that can be blended to organizational policies. The objective which corresponds to the main purpose of the paper is to provide a 5-staged MWH model, stemming from our evidence-based studies, that may speak for the identified need. We also discuss how the Model can provide a route map on how SMEs can implement and measure SDGs relevant to their business in synergistic interaction with SDG3. Full article

Solid waste management is one of the most important environmental issues worldwide, particularly in MENA countries. The present study was carried out in the city of Algiers, the capital city of Algeria. This urban area is marked by an increase in waste flow combined with a demographic surge. In order to investigate waste production and its drivers, we used both multiple regression and correlation analyses to test this dependence. Geospatial analysis was performed using principal component analysis integrated with GIS in order to look at the spatial distribution of waste management and potential drivers of waste production. The results indicate that household waste management is influenced by drivers related to the size of the settlement and the characteristics of waste management companies (p ≤ 0.05). The findings also show that none of the sociodemographic variables were found to significantly influence waste production. However, the spatial distribution is influenced by the geographic and sociodemographic characteristics of Algeria at all territorial levels. Algiers is still a landfill-based city in the MENA region, where mixed waste collection prevails in all districts. This study reinforces the importance of expanding source-separated waste collection schemes in order to increase the household waste diversion from landfills and, more importantly, shows how modern tools such as GIS, principal component analysis, and spatial analysis urban planning are useful for monitoring household waste, in line with circular economy principles.

Blockchain is a cutting-edge technology that is transforming and reshaping many industries. Hence, the adoption of Blockchain is becoming an increasingly significant topic. The number of publications discussing the potential of Blockchain adoption has been expanding significantly. In addition, not enough attention has been given to Blockchain adoption in the software development industry. As a result, a systematic overview to investigate the research trends in this area is needed. This study uses a Scientometric analysis and critical review to examine the evolution of Blockchain adoption research on the Web of Science Principal Collection. In addition, a systematic literature review (SLR) was conducted to identify gaps in Blockchain adoption research and the top reasons for adopting Blockchain with the intention of proposing a sustainable adoption framework. This study extends the body of knowledge by discussing the most influential countries, authors, organizations, publication themes, and most cited publications on Blockchain adoption research. Additionally, this study identifies the 30 relevant studies from the Web of Science and Scopus, including their industries, countries, methods, and respondent sample size, and the top 18 adoption factors among them. Consequently, this study proposes a suitable Blockchain adoption framework based on these top 18 factors. Finally, this study’s aim and unique contribution is to serve as an initial launching point for upcoming Blockchain adoption in software development industry research. Full article

The promotion of new electric and hybrid vehicles is a worldwide strategy to reduce carbon emissions for a clean future environment in many countries. In Europe, development of the electric vehicle (EV) industry is a strategic direction of multiple car-producing companies, institutes, and governments, but how sustainable it is to shift fully to electric has yet to be seen. By making use of the statistic reports from the European Union, scientific literature, and mathematical calculation, the author wants to examine if what politicians see will be a matter of reality in the near future. It will be proved that, if all private transport become electric, energy consumption will increase to such a level that is impossible to be satisfied by the actual energy producing companies. While the EV industry is seen as an important step towards achieving environmental goals, and despite some positive assumptions made by few European Governments (e.g., Norway) according to which electrical cars will replace the fossil fuel ones in private transportation, the actual energy market trends are not able to support the demand for the next several decades. The author will focus on one European country, Romania, to provide it as a case study (Romania is a self-sustainable country with regard to energy production, producing roughly 124% of its needs.).

Financial technology (FinTech) is one of the most important contributors applying technological applications to access financial products in financial markets. This research analyzes the determinants of financial knowledge and its impact on using FinTech services by employing survey data from a sample of 527 individuals in the southeast region of Vietnam, an emerging economy. The results indicate that women have a lower level of both actual financial knowledge and perceived financial knowledge than men. Moreover, men have a higher propensity to use FinTech services than women. Younger people also have higher FinTech usage compared with older people. Unlike previous studies in the financial field, an interesting finding emphasizes that actual financial knowledge does not affect the use of FinTech services but perceived financial knowledge does. To ensure the findings are robust, the research uses instrumental variable (IV) method, and 2SLS (two-stage least squares) estimation to resolve endogenous problems. Accordingly, to promote financial well-being, the findings suggest that financial institutions or FinTech firms should design and develop more user-friendly FinTech products and services so even older people can gain access to FinTech usage. Additionally, policymakers should devote attention to user protection in emerging economies where people are considered less financially literate. Full article

Mathematics teachers’ perceptions and awareness of different kinds of assessments (e.g., diagnostic, formative, and summative assessments) may affect their classroom practices. In this context, the current study explored mathematics teachers’ perceptions and self-reported practices teaching mathematics for Trends of International Mathematics and Science Study (TIMSS) in Abu Dhabi schools in the United Arab Emirates. A teacher perception questionnaire was designed, then was administered to 522 mathematics teachers in Abu Dhabi schools in the academic year 2020–2021. A One-Sample t-test, Independent Sample t-test, and ANOVA tests were performed for the four-component variables of teacher perceptions, namely, teachers’ perceptions of TIMSS, their instructional practices in relation to TIMSS, the readiness of students for TIMSS, and the school and classroom environment for TIMSS. The results showed no statistically significant difference between male and female teachers in mathematics teaching practices with a focus on TIMSS or their perceptions of student readiness for TIMSS; however, there were differences in their perceptions of the school and classroom environment that were statistically significantly. In addition, there was no statistically significant difference between public and private schools in the practice of mathematics teachers for TIMSS, while the difference was statistically significant on views regarding student readiness for the TIMSS as well as on the school and classroom environment. The findings of the present study have both pedagogical and policy implications, which are discussed at the end of this paper. Full article

Smallholder farmers across rural landscapes remain trapped in a vicious cycle of endemic poverty where interconnected challenges limit their ability to improve their livelihoods. Our study of smallholder farmers’ relationships with suppliers and several stakeholders across the Tanzanian rural agro-input supply chain offers an extended perspective on the persistence of endemic poverty and broadens the discussion on the future of sustainable food production and smallholder livelihoods. Through interviews and focus groups, we use a grounded theory methodology to develop a systemic approach to understanding the complexities of this landscape as related to smallholder agro-input sourcing activities. Our causal loop diagram framework provides a unique perspective on the poverty trap experienced by smallholder farmers in this context. Our findings may be useful in targeting practical and sustainable directions towards overcoming the poverty trap, ultimately enabling smallholders to increase wealth and improve their livelihoods through sustainable practices.

Insects offer a promising alternative source of protein to mitigate the environmental consequences of conventional livestock farming. Larvae of the black soldier fly (Hermetia illucens; Linnaeus, 1758) efficiently convert a variety of organic side streams and residues into valuable proteins, lipids, and chitin. Here, we evaluated the suitability of two palm oil industry side streams—empty fruit bunches (EFB) and palm kernel meal (PKM)—as larval feed, and their impact on the larval gut microbiome. Among 69 fungal species we screened, Marasmius palmivorus, Irpex consors, and Bjerkandera adusta achieved the fastest growth and lignin degradation, so these fungi were used for the pretreatment of 7:3 mixtures of EFB and PKM. Larvae reared on the mixture pretreated with B. adusta (BAD) developed significantly more quickly and reached a higher final weight than those reared on the other pretreatments or the non-fermented reference (NFR). Amplicon sequencing of the BAD and NFR groups revealed major differences in the larval gut microbiome. The NFR group was dominated by facultatively anaerobic Enterobacteriaceae (typical of H. illucens larvae) whereas the BAD group favored obligately anaerobic, cellulolytic bacteria (Ruminococcaceae and Lachnospiraceae). We hypothesize that fungal lignin degradation led to an accumulation of mycelia and subsequent cellulolytic breakdown of fiber residues, thus improving substrate digestibility. Full article

Despite the global focus on the COVID-19 pandemic, the promise of impact to tropical coastlines and stochasticity of destruction caused by tropical cyclones remains unaltered, forcing human societies to adapt to new unadaptable scenarios. Super Cyclone Amphan’s landfall—the third cyclone of the season within the world’s largest mangrove forest—brought a new uncertainty to this undeveloped region of South Asia. How do vulnerable people deal with multiple disasters that limit necessary humanitarian response while still maintaining the natural environmental integrity of a system harboring critical wildlife populations and protecting people from further disaster? We explored this reality for the Sundarbans region using a remote sensing technique and found that the western part of Sundarbans mangroves was severely damaged by Amphan, suggesting that rapid remote sensing techniques can help direct resources, and recognize the eventuality that response will be a best effort for now. If 2020 is a window, multiple disaster management scenarios may become more common in the future. Yet, society’s obligation for maintaining environmental integrity remains unchanged. Full article

Inclusive digital innovation (IDI) entails rolling out policies and digital innovations to ensure equal access to services and new goods by previously excluded and marginalized societies. Digital commerce (d-commerce) has the potential to foster an inclusive community through IDI empowerment in emerging economies; however, the literature on inclusive digital innovation and citizen empowerment is limited on the effect of e-strategy policies and empowerment on d-commerce adoption, use, and recommendation propensity. Underpinned by three theories: the Extended Unified Theory of Acceptance and Use of Technology, the citizen empowerment theory, and the affective decision-making theory of optimism bias and risk, this study proposes a model to establish the determinants of use intention, use behavior, and propensity to recommend d-commerce in disadvantaged and marginalized communities in South Africa. Using survey data from 983 disadvantaged d-commerce users to test the proposed model and hypotheses using IBM Amos for Windows and structural equation modeling (SEM), this paper provides a unique narrative to the empowerment discourse of marginalized people. Results show that privacy, security, trust, and citizen empowerment positively influence use intention and optimism bias, use behavior, and citizen empowerment mediate the propensity to recommend. Factors that promote or hinder citizens’ choices to use and recommend d-commerce are pertinent to scholars, government agencies, and regulators seeking better policy implementations to eradicate socio-economic inequalities, sustainable societies, and the empowerment of disadvantaged and marginalized people.

Environmental management accounting (EMA) practices guide a firm’s response to perceived environmental uncertainty (EU) and various institutional pressures (IP). Drawing upon institutional theory, this study explores the relative effects of institutional pressures and environmental uncertainty on the implementation of EMA, an environmental strategy (ES), and the resulting environmental performance (EP) of firms under the influence of top-management support (TMS) and perceived benefits (PB). Based on data collected from 243 firms operating in Suzhou, one of the busiest business hubs in China, this research used the structural equation modeling (SEM) technique. Findings reveal that environmental uncertainty exerts a stronger influence on the adoption of EMA practices than institutional pressures; however, the choice of a firm’s environmental strategy is more influenced by institutional pressures. Likewise, the serial-mediation effect of environmental strategy and EMA practices is observed to be the strongest in the case of coercive pressures, with some notable moderation effect for perceived benefits and top-management support. The study concludes with theoretical and managerial implications. Full article

The city of Bristol currently generates around 48,000 tonnes of household food waste every year. This waste incurs loss of resources and environmental damage throughout the food cycle. In this paper we quantify and value the baseline socio-environmental impacts from household food waste in Bristol before examining the potential costs and benefits that may result from changes to food waste behaviour. In so doing, we look to better inform the choice of food waste reduction methods in public policy. The environmental impacts of two possible policy targets are explored: (1) a 20% increase in food waste recycling and (2) an overall decrease in food waste of 20%. Environmental impacts are estimated for 13 different hazards, including Global Warming Potential, Particulate Matter, Human Toxicity and Water Depletion. The societal consequences of these environmental changes are monetised using non-market values which allows us to directly compare the relative importance of different environmental impacts and the trade-offs between these impacts in each scenario. For example, we estimate that the Global Warming Potential of Bristol’s annual food waste equates to around 110,000 tonnes CO₂, or 25,000 additional cars on the road every year. We find that a 20% improvement in recycling behaviour would lead to an annual reduction of 113 tonnes of CO₂ equivalent, whilst a 20% reduction in food waste would result in an annual reduction of 15,000 tonnes CO₂ equivalent. Findings suggest that the environmental impact of waste management is significantly overshadowed by the impact of resources used in food production and distribution before it becomes waste.

Marine litter is a significant threat to the marine environment, human health, and the economy. In this study, beach litter surveys along Vietnamese coasts were conducted in a local context to quantify and characterize marine litter using the modified GESAMP marine litter monitoring guideline. A total of 21,754 items weighing 136,820.2 g was recorded across 14 surveys from September 2020 to January 2021. Plastic was the most abundant type of litter by both quantity (20,744 items) and weight (100,371.2 g). Fishing gear 1 (fishing plastic rope, net pieces, fishing lures and lines, hard plastic floats) and soft plastic fragments were the most frequently observed items (17.65% and 17.24%, respectively). This study not only demonstrates the abundance and composition of marine litter in Vietnam, it also provides valuable information for the implementation of appropriate preventive measures, such as the redesign of collection, reuse, and recycling programs, and informs policy and priorities, with a focus on action and investment in Vietnam. Moreover, insights from this study indicate that citizen science is a useful approach for collecting data on marine litter in Vietnam. Full article
