Edible mushrooms are often regarded as a sustainable source of proteins, and several studies have sought to further improve the sustainability of this production. The vertical farming (VF) system could help to reduce the environmental impact during the cultivation of this crop. This study aimed to evaluate whether a VF cultivation system could increase the production and sustainability of Pleurotus species. In this study, P. cornucopiae (PC) and P. ostreatus (PO) were cultivated in a VF system using four-layer iron shelves arranged both individually and in combined configurations in the mushrooms greenhouse; a randomized block design with three replicates for each treatment was used. The impact of shelf layers on the productive traits of these crops was also evaluated, comparing upper layers to the ground layer (Control). In addition, a Life Cycle Assessment (LCA) analysis was carried out to compare the environmental impact of VF and a conventional cultivation system for PO. The results demonstrated that the shelf layer influenced primordia formation, yield, and morphological characteristics. PC exhibited optimal growth in the upper layers, whereas PO performed better in the lower layers, reflecting their respective temperature preferences. The shelf configuration affected light exposure and primordia induction but did not significantly influence overall yield or morphology. The VF system had a lower overall environmental burden, in particular, considering the climate change impact (−27%) and fossil fuel consumption (−37%) compared to conventional cultivation. Among the phases, substrate production had the highest impact due to the higher substrate needed. In conclusion, VF for Pleurotus production enhanced both the productivity and the sustainability of this crop, but further study regarding the economic analysis of this system is needed to assess the industrial application of this system.

Laos, a resource-rich and politically stable country in Southeast Asia, has experienced rapid economic expansion driven by foreign investments in hydropower, mining, and industrial park development. While these sectors have contributed substantially to national growth, they have also intensified environmental degradation and social pressures. This study critically evaluates the effectiveness of the Environmental and Social Impact Assessment (ESIA) system in Laos within the broader framework of environmental governance and sustainable development. A qualitative research design was employed, combining legal and policy document analysis, review of secondary literature, and case studies of three representative projects. The findings reveal that, although Laos has established a comprehensive ESIA regulatory framework, its implementation remains constrained by weak institutional capacity, overlapping administrative mandates, and limited technical resources. Furthermore, low levels of public participation and transparency reduce the inclusiveness and credibility of ESIA processes. Despite these challenges, recent legal reforms and growing international cooperation demonstrate gradual progress toward more accountable and integrated environmental governance. Strengthening institutional capacity, enhancing inter-ministerial coordination, and incorporating social considerations into project evaluations are essential steps to transform the ESIA framework from a procedural obligation into a robust tool for promoting sustainable and responsible investment in Laos.

The present paper analyses the extent to which European Union regulatory frameworks induce the development of circular agriculture within the European Union. In order to evaluate the progress towards circular agriculture within the European Union, a composite Agricultural Circularity Index (ACI) was developed for all EU-27 Member States for the period of 2014–2023. An expert interview and a TOPSIS multi-criteria decision-making technique were employed for the construction of the ACI. Results indicate only marginal improvements in the development of circular agriculture on the aggregate EU level, although a pronounced cross-country divergence towards achieving circularity in agriculture was observed. The following four distinct trajectories in the evolution of the circular economy within the EU were distinguished: structurally advancing promoters, short-term breakthrough cases, high baseline, but eroding systems, and mixed or stagnating countries. Indicator decomposition analysis reveals that durable circularity gains in agriculture arise when increased material recirculation coincides with verifiable bandwidth, whereas intensifying input use frequently negates the progress. The findings underscore that regulatory ambition alone is insufficient: implementation design, uncompromised enforcement, and market integration determine whether initial initiatives towards circular agriculture materialize into sustainable practices or remain transitory. From a policy perspective, the ACI functions as a diagnostic tool to locate structural bottlenecks and to target CAP-style interventions where circular flows can be scaled most effectively.

The growing use of electric vehicles (EVs) creates challenges in designing charging systems that are smart, dependable, and efficient, especially when environmental conditions change. This research proposes a fuzzy-logic-based PID control strategy integrated into a photovoltaic (PV) powered EV charging system to address uncertainties such as fluctuating solar irradiance, grid instability, and dynamic load demands. A MATLAB-R2023a/Simulink-R2023a model was developed to simulate the charging process using real-time adaptive control. The fuzzy logic controller (FLC) automatically updates the PID gains by evaluating the error and how quickly the error is changing. This adaptive approach enables efficient voltage regulation and improved system stability. Simulation results demonstrate that the proposed fuzzy–PID controller effectively maintains a steady charging voltage and minimizes power losses by modulating switching frequency. Additionally, the system shows resilience to rapid changes in irradiance and load, improving energy efficiency and extending battery life. This hybrid approach outperforms conventional PID and static control methods, offering enhanced adaptability for renewable-integrated EV infrastructure. The study contributes to sustainable mobility solutions by optimizing the interaction between solar energy and EV charging, paving the way for smarter, grid-friendly, and environmentally responsible charging networks. These findings support the potential for the real-world deployment of intelligent controllers in EV charging systems powered by renewable energy sources This study is purely simulation-based; experimental validation via hardware-in-the-loop (HIL) or prototype development is reserved for future work.

Plant awareness, which refers to the ability to notice, value, and understand the importance of plants, has emerged as a significant research field, particularly considering the growing concerns about sustainability and biodiversity loss. Acknowledging the crucial role of plants in sustaining life on Earth and human well-being, several studies highlight the need for educational interventions that can meaningfully enhance plant awareness. In this context, the present study aims to design, implement, and evaluate a Teaching–Learning Sequence (TLS) with university students in a Pedagogical Department. The TLS was grounded in the principles of transformative learning, an educational approach focused not merely on the transmission of knowledge but on fostering deep, personal shifts in learners’ perceptions and attitudes. To assess its impact, the Plant Awareness Disparity Index (PAD-I) was used before and after the implementation, supported by systematic observations and focus group discussions. Results indicate that the TLS effectively enhanced specific dimensions of plant awareness, particularly relative interest between plants and animals and attitudes toward plants. These findings position transformative learning as a promising pedagogical framework for promoting plant awareness in higher education and pave the way for its future application in earlier educational levels.

The rapid urbanization of recent decades has intensified the need for sustainable and adaptive city models that balance economic growth, environmental protection, and social well-being. This study addresses the challenge of assessing the performance of European smart cities by proposing a composite index of urban sustainability based on citizens’ perceptions. Using data from the Quality of Life in European Cities Survey (2023), the research applies a multi-criteria analytical framework grounded in the Benefit-of-the-Doubt (Data Envelopment Analysis) approach, which allows each city to determine optimal indicator weights and eliminates pre-assigned biases. The analysis integrates six dimensions of smart city performance—mobility, living, environment, economy, governance, and people—to evaluate cities’ adaptability to the needs of their residents. Results reveal that cities such as Aalborg (Denmark), Luxembourg (Luxembourg), Cluj-Napoca (Romania), and Zurich (Switzerland) exhibit the highest performance, demonstrating balanced progress across sustainability-oriented domains. The findings suggest that integrating citizens’ evaluations with data-driven weighting provides a more comprehensive and context-sensitive understanding of urban sustainability. The study concludes that the proposed composite index provides a robust methodological framework for benchmarking European smart cities, supporting policymakers in designing targeted strategies for enhancing livability, inclusiveness, and sustainable urban growth.

Coastal cities face escalating flood risk under sea-level rise, yet landscape-based adaptation strategies often remain speculative and weakly connected to the accessibility and economic constraints that shape sustainable urban development. This study developed a modeling-to-design framework that translates coupled climate and land-use projections into implementable landscape interventions, through planning-level spatial allocation, using Dalian, China as a case study under “middle of the road” (SSP2-4.5) climate conditions. The framework integrates the Land-use Evolution and Assessment Model (LEAM) with connected-bathtub flood modeling to evaluate whether strategic landscape design can redirect development away from flood-prone zones while accommodating projected growth and maintaining accessibility to employment and services. Interventions—protective wetland restoration (810 km²) and blue–green corridors (8 km²)—derived from a meta-synthesis of implemented coastal projects were operationalized as LEAM spatial constraints. Our results show that residential development can be redirected away from coastal risk with 100% demand satisfaction and elimination of moderate-risk allocations. Cropland demand was fully accommodated. In contrast, commercial development experienced 99.8% reduction under strict coastal protection, reflecting locational dependence on port-adjacent sites. This modeling-to-design framework offers a transferable approach to quantifying where landscape interventions succeed, where they face barriers, and where complementary measures are required, supporting decision-making that balances environmental protection, economic function, and social accessibility in sustainable coastal development.

The rapid growth of electric vehicles (EVs) has introduced new fire safety challenges for the built environment, particularly within reinforced concrete structures. Fires involving lithium-ion batteries are substantially different from conventional hydrocarbon-fuelled fires due to their rapid heat escalation, extended burning duration, and potential for re-ignition caused by thermal runaway. This study assesses the adequacy of existing fire design standards in addressing these emerging hazards, emphasising the spalling behaviour of concrete under EV induced fire exposure. The study found that concrete structures are highly vulnerable to spalling when exposed to EV fires, as the typical temperatures initiating concrete spalling are significantly lower than the extreme temperatures and re-ignition produced during an EV battery fire. Moreover, the evidence suggests that EV fires can sustain peak temperatures exceeding 1000 °C in a short period, which exceeds the assumptions underlying standard fire curves, such as ISO 834. A comparative assessment of the National Construction Code (NCC 2022) and standards (i.e., AS 1530.4, EN 1992-1-2) reveals that current design methodologies and fire-resistance ratings underestimate the severity and duration of EV fire conditions. This study also proposes code-aligned improvements and a performance-based evaluation framework that integrates empirical EV fire curves. The findings highlight a pressing need to re-examine fire design provisions and update thermal exposure assumptions to ensure that reinforced concrete infrastructure remains structurally safe and reliable as EV adoption increases.

Community gardening has become an important urban sustainability initiative that integrates ecological restoration with social participation. However, little is known about the psychological and social mechanisms that drive citizens’ willingness to engage in such activities, particularly in densely populated cities with limited green space. This study develops and empirically tests an integrative behavioral model combining environmental psychology, social cognitive theory, and environmental identity theory to explain citizens’ participation in community gardening in Tehran, Iran. Using survey data from 416 residents and analyzing results through structural equation modeling, the study evaluates the effects of six key predictors, including childhood nature experience, connectedness to nature, self-efficacy, outcome expectancy, psychological restoration, and collective environmental responsibility, on willingness to participate. The model explained 54% of the variance in participation, indicating high explanatory power. Five predictors significantly influenced willingness to participate: childhood nature experience, connectedness to nature, outcome expectancy, psychological restoration, and collective environmental responsibility, while self-efficacy was not significant. The findings reveal that engagement in community gardening is shaped more by emotional, restorative, and moral motivations than by perceived capability alone. Theoretically, this research advances understanding of pro-environmental participation by integrating memory-based, affective, and normative dimensions of behavior. Practically, it provides actionable insights for urban planners and policymakers to design inclusive, emotionally restorative, and collectively managed green initiatives that strengthen citizen participation and enhance urban resilience.

Taiwan’s rural regions face aging populations, digital divides, and fragmented heritage narratives that limit sustainable cultural revitalization. This study investigates how a community-based Alternate Reality Game (ARG) can integrate dispersed cultural assets in Shiding District into a coherent, immersive experience that supports intergenerational learning and community engagement. Drawing on ARG/transmedia narrative theory, scaffolding theory, intergenerational learning, and value co-creation, the research adopts an exploratory sequential mixed-methods design: qualitative interviews and co-design workshops inform ARG system development, followed by field implementation and pre–post evaluation with 78 participants across three age groups. The results show large improvements in user experience and immersion, while quantitative changes in cultural understanding, perceived learning support, and community engagement are modest and not consistently positive, despite rich qualitative accounts of heightened awareness of local history and community life. Participants’ narratives highlight a reciprocal scaffolding dynamic, in which younger visitors provide digital assistance and older residents contribute local knowledge, as well as strong perceptions of co-creation with community hosts. These findings suggest that a low-cost, participatory ARG can effectively reduce on-site narrative fragmentation and foster emotionally engaging, intergenerational experiences, but that deeper and more durable cultural learning effects likely require refined measurement and longer-term engagement. The study contributes an integrated design and evaluation framework for rural ARG applications and offers practical guidelines for communities and policymakers seeking inclusive, story-driven models of digital heritage revitalization.

Widespread antibiotic residues in aquatic environments pose escalating threats to ecological stability and human health, highlighting the urgent demand for effective remediation strategies. In recent years, photocatalytic technology based on advanced nanomaterials has emerged as a sustainable and efficient strategy for antibiotic degradation, enabling the effective utilization of solar energy for environmental remediation. This review provides an in-depth discussion of six representative categories of photocatalytic nanomaterials that have demonstrated remarkable performance in antibiotic degradation, including metal oxide-based systems with defect engineering and hollow architectures, bismuth-based semiconductors with narrow band gaps and heterojunction designs, silver-based plasmonic composites with enhanced light harvesting, metal–organic frameworks (MOFs) featuring tunable porosity and hybrid interfaces, carbon-based materials such as g-C₃N₄ and biochar that facilitate charge transfer and adsorption, and emerging MXene–semiconductor hybrids exhibiting exceptional conductivity and interfacial activity. The photocatalytic performance of these nanomaterials is compared in terms of degradation efficiency, recyclability, and visible-light response to evaluate their suitability for antibiotic degradation. Beyond parent compound removal, we emphasize transformation products, mineralization, and post-treatment toxicity evolution as critical metrics for assessing true detoxification and environmental risk. In addition, the incorporation of artificial intelligence into photocatalyst design, mechanistic modeling, and process optimization is highlighted as a promising direction for accelerating material innovation and advancing toward scalable, safe, and sustainable photocatalytic applications.

Placed at the core of the energy transition, the integrated oil and gas sector is facing growing pressure to balance sustainability requirements with financial performance. While ESG ratings are widely used to evaluate and benchmark corporate sustainability, their connection to broader SDG commitments (and real transition outcomes) remains underexplored, especially in carbon-intensive industries. Against this background, this paper aims to investigate how well the world’s largest integrated oil and gas companies (as classified by LSEG Data and Analytics) align their ESG performance with the SDGs, and to assess (the robustness of) their sustainability trajectories. Using a panel dataset—including ESG (overall, by pillars, and controversies) scores (2019–2023), SDG commitments (2019–2023), and the (recently released) FTSE Russell Green Revenues (2024)—the study applies a quantitative, longitudinal, and explanatory design. It follows a process logic—from inputs (ESG performance) to intentions (SDG commitments) and ultimately to outcomes (Green Revenues)—to identify performance patterns, strategic archetypes, and materiality insights. The study adds to the ongoing debate on how ESG metrics can better capture real SDG/sustainability impacts, while providing insights for strategists, investors, and policymakers seeking to align financial and sustainability agendas during the energy transition.

This study aimed to synthesize a magnetic biochar@ZIF-8 composite derived from almond shell biomass for the adsorption of fluoroquinolones (FQs) from aqueous media. The biochar was prepared under different pyrolysis conditions using a central composite design (CCD) based on temperature and residence time, with biochar yield (%) and ofloxacin adsorption capacity selected as the response variables. Subsequently, the composite was obtained by combining KOH-activated biochar with ZIF-8 and magnetic particles, producing a hierarchically porous material with enhanced surface area and functional groups favorable for adsorption. The physicochemical and morphological properties of the composite were characterized by SEM–EDS, FTIR, BET, TGA, and XRD analyses, confirming the successful incorporation of ZIF-8 and magnetic phases onto the biochar surface. The adsorption performance was systematically evaluated by studying the effects of pH and contact time. The kinetic data fitted well to the pseudo-second-order model, suggesting that chemisorption predominates through π–π stacking, hydrogen bonding, and coordination interactions between FQ molecules and the active sites of the composite. Furthermore, the material exhibited high reusability, maintaining over 84% of its adsorption capacity after four cycles, with efficient magnetic recovery without the need for filtration or centrifugation. Overall, the magnetic biochar@ZIF-8 composite demonstrates a sustainable, cost-effective, and magnetically separable adsorbent for water remediation, transforming almond shell waste into a high-value material within the framework of circular economy principles.
