Sustainability in higher education plays a crucial role in shaping future professionals with an eco-conscious mindset. This study focuses on developing and simulating a portable solar food dehydrator as a practical application of sustainability principles in technology education. By integrating sustainability into the curriculum, this research enhances students’ technical skills while promoting the use of renewable energy and effective food preservation methods. Furthermore, the project aligns with green campus initiatives by encouraging energy-efficient practices and reducing food waste. This study emphasizes the significance of education for sustainable development by offering learners hands-on experience in designing eco-friendly solutions, promoting innovation, and equipping them to contribute to a more sustainable future. A food dehydrator is a device that removes moisture from food to aid in its preservation, utilizing a heat source and airflow to reduce its water content. The researchers used two methods to dehydrate food: direct sunlight (sun drying) and indirect sunlight (solar drying). The study used a developmental research design. Simulations revealed that, with solar-powered electricity, the longer the drying time, the greater the reduction in the moisture content. This was evident in the eighth experiment, which was conducted on fruits and vegetables. While drying with direct sunlight, the same trends, albeit to a lesser extent, were observed in the reduction in the moisture content of the fruits and vegetables. These insights can inform future design improvements, making the products more visually appealing and distinctive, thereby enhancing their attractiveness and novelty. Full article

Environmental research and development (R&D) support environmental improvement by advancing cleaner technologies, improving resource efficiency, reducing emissions, and helping firms meet sustainability goals and regulatory standards. This study examines the effect of environmental R&D on firms’ environmental performance and considers whether firm characteristics, specifically age and size, moderate this relationship. Using purposive sampling based on defined inclusion and exclusion criteria, the analysis draws on data for 303 non-financial firms listed on the Frankfurt Stock Exchange between 2007 and 2024, obtained from Refinitiv DataStream. Diagnostic tests revealed cross-sectional dependence, heterogeneity, and endogeneity in the dataset. To address these issues and ensure robust estimates, the Common Correlated Effects Mean Group (CCEMG), Feasible Generalized Least Squares (FGLS), and two-step difference Generalized Method of Moments (GMM) estimators were employed. The results show that environmental R&D has a positive and significant effect on environmental performance. Firm age and size further strengthen this relationship, indicating that older and larger firms benefit more from environmental R&D initiatives. The study recommends that firms increase investment in environmental R&D to stimulate innovation, enhance sustainable practices, and improve ecological outcomes. Policymakers should also encourage eco-innovation by developing supportive regulations, offering financial incentives for green technologies, and promoting sustainable technological advancement.

The concept of awareness in the visual arts has become an ethical, professional, and social imperative. Adopting a sustainable approach to creative practice is no longer a trend but an established and necessary field of inquiry. Within this context, awareness has been expressed not only through eco-branding and design campaigns but also through artworks and contemporary artistic practices that embody sustainable values both aesthetically and philosophically. Visual arts thus function as a reflective and critical tool, capable of reassessing past and present paradigms, encouraging more responsible uses of resources, promoting environmental sustainability, and shaping public attitudes through conscious and critical forms of expression. This study adopts a qualitative approach to examine transformations in contemporary art practices within the Saudi Arabian art scene. Selected artworks are analysed to explore historical and conceptual narratives shaping artistic production. The research is based on a bibliographic and documentary review that includes academic literature, exhibition catalogues and press sources related to the Saudi cultural context. Data are gathered through observing artworks and, where possible, through interviews with artists. A comparative analysis was developed, with the study framed by art practices, their concepts, and their ecological contributions, leading to a sustainable awareness and their potential role in encouraging social change. The comparative study among artists provides an innovative research framework and initiates a broader dialogue on sustainable creative practices rooted in Saudi cultural contexts. The findings highlight how visual arts contribute to ecological awareness and climate activism through art installations, recycled materials, and digital practices, reinforcing sustainability as a core value within contemporary Saudi society.

This study examines the effects of digital sustainability orientation on consumers’ responses, with a focus on the roles of digital green innovation and consumer environmental consciousness in shaping green brand advocacy in social media marketing. Drawing on the Resource-Based View, Dynamic Capability perspective, and Signaling theory, the study proposes that sustainability-oriented digital strategies are more effective when translated into visible, credible forms of digital green innovation. Using the quantitative research design, data were collected from a sample of 300 Saudi Arabian consumers who interact with eco-friendly brands and sustainability-related content on digital platforms such as Facebook, WhatsApp, Instagram, and TikTok. The study used purposive and convenience sampling to ensure that participants were aware of sustainability communication online. Data analysis was performed using Partial Least Squares-Structural Equation Modeling (PLS-SEM) to test the measurement and structural models and evaluate the hypotheses. The results show that the direct positive effect of digital sustainability orientation on digital green innovation is high, but there is no direct effect on green brand advocacy. However, digital green innovation fully mediates this relationship, making the importance of tangible innovation even greater in turning sustainability intentions into consumer support. Moreover, consumer environmental consciousness plays a significant moderating role in the relationship between digital sustainability orientation and green brand advocacy, suggesting that the more environmentally conscious consumers are, the more responsive they are to sustainability-driven digital strategies. The study contributes to the available literature on digital sustainability and green marketing by showing that being sustainability-oriented is not enough to encourage consumer advocacy without having credible innovation. Practically speaking, the findings show that organizations must pay attention to innovation-based sustainability initiatives and develop genuine digital communication strategies to attract environmentally conscious consumers. Ultimately, the research serves as a great reminder of the importance of integrating digital innovation, sustainability practices, and consumer engagement as key drivers of strong green brand advocacy.

This review provides a comprehensive analysis of the multiple factors influencing sunscreen efficacy, integrating studies published between 2016 and 2026. Beyond the type and concentration of UV filters, sunscreen performance is strongly affected by formulation design, photostability, environmental exposure, and user application practices. Formulation strategies involving emulsion systems, excipients, solubilization methods, and encapsulation technologies directly influence sun protection factor (SPF), cosmetic acceptability, and safety. Recent advances, including nanoparticle-based carriers, hybrid organic–inorganic systems, and antioxidant-enriched formulations, have shown potential to improve photostability, broaden UV protection, and reduce systemic absorption and environmental impact. However, inadequate application and insufficient reapplication remain major limitations to real-world photoprotection. In addition, differences in skin type, age, and lifestyle reinforce the need for more personalized sunscreen approaches. Growing concerns regarding the environmental effects of UV filters also highlight the importance of sustainable formulations and stricter regulatory policies. Overall, optimizing sunscreen efficacy requires not only technological innovation but also improved public education, transparent labeling, and user adherence. Future research should focus on multifunctional, eco-friendly, and user-centered sunscreens capable of providing effective and sustainable photoprotection. Full article

Wildfire prediction using machine learning (ML) and deep learning (DL) has expanded rapidly, yet synthesis regarding algorithmic configurations, data practices, and transparency remains limited. This systematic review characterizes ML/DL applications in wildfire prediction (2020–2025) using a PRISMA-EcoEvo framework across 341 peer-reviewed studies, with detailed analysis of 110 articles from 2024. Publication output increased steadily, concentrated geographically in China and the United States. Methodologically, ensemble tree-based methods (26.7%) and deep learning architectures (59.4%) coexist, reflecting adaptation to diverse data modalities. Input data are dominated by vegetation/fuel characteristics (44.7%) and historical fire labels (41.2%), while socioeconomic variables remain marginal (1.2%). Evaluation practices distinguish classification and regression tasks, yet metric heterogeneity constrains cross-study comparability. Critically, only 7.7% of studies provided publicly accessible code, with a significant association between algorithm family and code availability (χ² = 78, p = 0.0012). Collectively, wildfire ML/DL research demonstrates technical advancement but remains geographically concentrated and constrained by limited transparency. Strengthening reporting standards, metric-task alignment, dataset documentation, and open-code practices is essential to translate computational innovation into globally robust, reproducible wildfire decision-support systems.

Universities are increasingly positioning sustainability as a core institutional commitment, often publishing annual reports that showcase their contributions to the 17 Sustainable Development Goals (SDGs). Yet these documents frequently go unnoticed by the academic community, limiting their educational impact and their potential to inspire informed, responsible, and sustainable behaviors. To address this gap, this study explores how participatory and technology-enhanced educational approaches can transform sustainability reporting into an accessible, engaging, and pedagogically meaningful learning experience. Engaging 121 university students during a participatory process, we developed an interactive digital system that integrates innovative strategies, including interactive data visualizations, gamification, and a chatbot capable of dialoguing with the university’s sustainability report, to foster environmental awareness and promote sustainable practices. The system aims to empower learners on two intertwined levels: (i) understanding the institution’s sustainability actions and commitments, and (ii) recognizing concrete, everyday opportunities to contribute to environmental wellbeing, thereby counteracting feelings of eco-powerlessness and supporting agency-driven behavioral change. Findings highlight the effectiveness of participatory design in shaping impactful digital tools for sustainability education and demonstrate how interdisciplinary design principles can enhance student engagement with complex environmental issues. The study contributes to ongoing scholarly discourse by proposing six key guidelines (technology, content, data producer, learning strategy, gamification, and data visualization) for designing interactive systems that support education for a more resilient and sustainable future.

The evolution from Industry 4.0 to Industry 6.0 represents a paradigm shift—moving from automation toward an integrated model that incorporates intelligentization, sustainability, and human-centric resilience. While numerous conceptual frameworks have been put forward, empirical research remains scarce, primarily because of the absence of standardized indicators derived from verifiable corporate disclosures. To fill this research gap, the present study develops three quantifiable indices—Intelligence (INT), Sustainability (SUS), and Resilience & Human-centric (RES)—by extracting data from the annual reports and ESG disclosures of 100 Chinese A-share manufacturing enterprises (covering 2022–2024). Fixed-effects panel regression models are employed to assess the impact of these indices on financial performance (ROA, ROE, EPS), market valuation (Tobin’s Q), and sustainability outcomes (ESG ratings). Our findings reveal that INT is the most significant predictor of profitability, with statistically significant positive effects on ROA and ROE—effects that are particularly pronounced among high-tech enterprises. This supports the view that digital capabilities serve as strategic assets. SUS also demonstrates a positive influence on performance, especially in non-high-tech enterprises, where eco-efficiency, regulatory compliance, and ESG-linked financing help offset technological disadvantages. RES contributes to operational and financial stability by enhancing human capital, safety protocols, and organizational practices that reduce performance volatility. Collectively, these results indicate that different types of enterprises follow distinct yet converging pathways toward Industry 6.0: high-tech enterprises capitalize on intelligence to generate innovation rents, while non-high-tech enterprises increasingly rely on sustainability and resilience as strategies to build legitimacy. This study makes significant contributions in three aspects: Methodologically, it differs from previous research that relies on questionnaires and interviews. Instead, it quantifies Industry 6.0 through auditable large-sample key indicators, enhancing the objectivity and operability of the indicators. Empirically, it provides the first empirical evidence on the development path of Industry 6.0 based on data from Chinese manufacturing enterprises. In practical terms, it offers clear references for enterprises and policymakers on the core indicators and their construction framework that should be prioritized during the transformation to Industry 6.0. By linking the index derived from enterprise disclosures with quantifiable performance results, this study effectively bridges the gap between theoretical conceptions and practical applications. It further emphasizes that Industry 6.0 is not merely a technological upgrade but a systematic transformation driven by digitalization, sustainability, and resilience aimed at enhancing enterprise performance and achieving sustainable industrial development.

To solve the problem of mechanical entrainment and slime coating of fine sericite and chlorite hindering the flotation separation of gold-bearing pyrite in low-grade gold ores, ethylenediamine-N,N’-disuccinic acid (EDDS) was innovatively used as a selective and eco-friendly depressant. A systematic set of tests, including micro-flotation, artificial mixed mineral flotation, zeta potential measurement, adsorption capacity test, solution chemistry analysis and X-ray photoelectron spectroscopy (XPS) characterization, was conducted to explore its flotation performance and action mechanism. The results showed that pH 8 and 200 mg/L EDDS were the optimal conditions under which EDDS reduced the recoveries of sericite and chlorite to ~20% and ~15%, respectively, while restoring pyrite recovery to ~80% with a notable upgrade in concentrate grade. EDDS exhibited strong chemical adsorption on sericite and chlorite via chelating their active Al/Mg sites, significantly enhancing their hydrophilicity. In contrast, it only undergoes weak physical adsorption on pyrite, with negligible observed influence on its hydrophobicity and the adsorption of (sodium butyl xanthate) SBX. At pH 8, EDDS mainly existed as HEDDS³⁻ (~90%), whose triple negative charge strengthened electrostatic interaction with positively charged gangue surfaces, boosting selective adsorption. This study confirms EDDS as a highly efficient depressant for pyrite–sericite/chlorite flotation under pure mineral and artificial mixed mineral conditions. Since the present study is based on pure minerals and artificial mixtures, further validation using real ore samples is still required before practical industrial application. This research expands the application of EDDS in mineral processing and provides a novel eco-friendly technical approach for the laboratory-scale separation of fine gold-bearing pyrite from low-grade gold ores with high clay gangue content.

The increasing demand for environmentally sustainable and efficient laundry detergents has prompted the exploration of innovative biotechnological solutions. This study aims to integrate solid fermentation and by-product valorization for high-quality proteases suitable for laundry detergents. Of 486 strains isolated from fruit by-products, 9 were selected for their proteolytic activity, but only 3 showed proteolytic activity in the presence of detergent components. Strain M17, identified as Yarrowia lipolytica (Yl), proved to be the most effective in producing proteolytic extracts with activity similar to that found in commercial detergents. The produced proteases were incorporated into laundry detergent formulations, and their enzyme activity was compared with that of commercial laundry detergents. The results showed that the proteolytic extracts have enzyme activity similar to that of commercial laundry detergents. Culture media were developed to enhance protease production using fruit by-products. The highest activity (43.71 U (g dm)⁻¹) was achieved at C/N = 20.04, while the best productivity (1.37 U (g dm·h)⁻¹) at pH 7.0 and 30 °C was observed. The results demonstrate that culture media based on fruits and vegetable by-products enhance protease yield and activity. This approach not only reduces waste but also adds value to natural resources through an environmentally friendly process. This study underscores the potential of combining solid-state fermentation with by-products. Using Yl in combination with fruit and vegetable by-products is a practical, eco-friendly method for producing high-quality proteases for laundry detergents. This green enzyme innovation offers significant promise for advancing the detergent proteolytic enzymes and promoting sustainable practices in by-product management. Full article

Aquaculture marks the transition from the simple activity of harvesting aquatic animal resources, carried out through the catching practices of fishing, to the farming of aquatic organisms in fresh, brackish and sea waters, carried out through human intervention aimed at increasing production.

Promoting substantive green innovation is the core pathway for enterprises to achieve sustainable development. However, its inherent characteristics of high investment and high risk often result in insufficient innovation motivation among enterprises. Rooted in the Resource-Based View (RBV) and Dynamic Capability Theory (DCT), the research investigates the influence of underlying technology digital transformation on enterprises’ substantive green innovation. Using panel data from Chinese A-share listed firms (2009–2024), this analysis reveals a significant promotional effect of underlying technology digital transformation on substantive green innovation. The robustness of this conclusion is confirmed by a battery of tests. Mechanism analysis demonstrates that this effect functions mainly through two pathways: “technology empowerment” and “governance optimization”, namely enhancing corporate R&D capability and improving ESG performance. Heterogeneity analysis further indicates that this promotional effect is more prominent in enterprises with higher environmental disclosure levels and better internal control quality. This study elucidates the internal mechanism and boundary constraints by which underlying technology digital transformation empowers substantive green innovation, thereby offering micro-level evidence for comprehending the in-depth integration of digital technologies and eco-friendly development. The findings offer important practical implications for firms in formulating effective “digitalization–greenization” synergy strategies. Full article
