The electrical and electronic equipment (EEE) sector focuses on end-product lifecycle management as electronic waste (e-waste) alongside recycling and recovery operations for supply chain inclusion of components. This transformation faces considerable difficulty, primarily in developing economies, due to structural, regulatory, and technological barriers. The study identifies key impediments in e-waste supply chain systems by analyzing social, economic, and environmental sustainability factors, government regulations, technological advancements, and operational challenges. Using multi-iteration fuzzy Delphi, the factors were refined to 14 critical impediments, which were then prioritized and evaluated through fuzzy WINGS (Weighted Influence Nonlinear Gauge System). The findings highlight key cause impediments, including the dominance of the informal sector in e-waste handling (IIS), Ineffective policies and regulations (IPR), and Insufficient supply of e-waste to formal recycling centers (ISS), which significantly disrupt the efficiency of formal recycling processes. A comparative analysis with fuzzy DEMATEL revealed discrepancies in the influence of certain impediments, while sensitivity analysis confirmed the robustness and stability of the model.

Employing data from 1987 to 2020 and applying the Dynamic ARDL simulation approach, the study analyzes both direct and moderating effects of AI on green growth. The outcomes illustrate that while REG alone has a statistically insignificant impact on green growth (0.073 %), AI and GTI significantly promote long-term green growth. Specifically, AI contributes 0.241 % and GTI 0.163 % to long-term green growth, supporting SDG 8 (Decent Work and Economic Growth) and SDG 9 (Industry, Innovation, and Infrastructure). Moreover, interaction effects show that AI significantly enhances the effectiveness of REG (with an interaction coefficient of 0.017 %), facilitating a cleaner energy transition in line with SDG 7 (Affordable and Clean Energy). Similarly, AI enhances the contribution of GTI (with an interaction coefficient of 0.041 %), reinforcing environmental quality in support of SDG 13 (Climate Action). Robustness checks via the KRLS estimator confirm these relationships. Policy implications suggest that integrating AI into energy and innovation policies can amplify sustainability outcomes.

This study evaluates the effectiveness of woodchip-biochar bioreactors in reducing nitrogen loads in agricultural drainage ditches. Biochar, a highly porous and recalcitrant form of charcoal, was incorporated alongside woodchips due to its known capacity to enhance microbial activity and nutrient retention. Three field-scale bioreactors, composed of a 50:50 volumetric mix of woodchips and biochar, were installed in experimental ditches, with three control ditches left untreated. Over an 18-month monitoring period, nitrate concentrations in bioreactor pore water were reduced by an average of 87 % compared to control ditches, suggesting that denitrification - a microbial process converting nitrate to nitrogen gas in low-oxygen conditions - played a dominant role. Biochar amendment enhanced microbial habitat, improved pH buffering, and increased nutrient retention, fostering conditions favorable for denitrification. Prokaryotic amplicon sequencing revealed a distinct microbial community structure in biochar-amended bioreactors, with enrichment of denitrifying taxa and elevated functional potential for nitrogen removal. While transient increases in ammonia and dissolved organic carbon were observed post-installation, these effects did not extend beyond the bioreactor pore water and diminished over time.

The composite, with an effective active iron species content as high as 34 %, demonstrated excellent performance in the removal of bisphenol A (BPA) in the peroxymonosulfate (PMS) system. The Fe-MCGFS-800 could achieve a 93.1 % removal rate of BPA within 60 min, with a kinetic reaction rate of 0.0418 min^-1.

The ketone group structure and abundant iron species in Fe-MCGFS-800 could activate PMS to generate reactive oxygen species (ROS), which played a dominant role in the BPA degradation process. Specifically, the bondage of iron species could be broken by the mechanochemical method, and this method promoted the phase transformation and the formation of active centers. Moreover, the migration of iron species enhanced the electron-transfer ability, promoting the degradation of BPA through non-radical pathways.

Results showed that the relative abundance of microbial CAZymes degrading plant-derived C (cellulose, hemicellulose, lignin, 90.87-91.72 %) exceeded that degrading microbial-derived C (8.28-8.13 %). Additionally, CAZymes degrading bacterial-derived C (peptidoglycan, 6.60-7.46 %) was higher than that degrading fungal-derived C (chitin and glucans, 1.37-2.20 %). Intriguingly, temporal dynamics revealed non-linear dynamics-SOC content, enzyme activities, and plant-/microbial-derived C peaked at 7-year of afforestation before declining in 10-year of afforestation. Afforestation reduced the abundance of genes degrading plant-derived C, including cellulose- and hemicellulose-specific gene families. In contrast, the abundance of genes degrading bacterial-derived C showed a decreasing and then increasing trend as afforestation, while genes degrading fungal-derived C showed the opposite trend. In summary, afforestation-induced changes in soil nutrients alter the abundance of microbial functional genes degrading bacterial-, fungal-, and plant-derived C, thereby influences SOC dynamics through these C components.

The main objective of this study is to estimate the Italian technical potential for advanced biomethane production, focusing on feedstocks eligible under the European Union's Renewable Energy Directive for advanced biofuels production. These feedstocks include agro-industrial residues, livestock manure, sewage sludge, cheese whey, and the organic fraction of municipal solid waste. The technical potential represents the maximum amount of biomethane that could be produced from available feedstocks, without considering economic feasibility or competition with other uses. Regional data on processes generating these residues and statistical data on waste streams have been processed and aggregated to create geographically explicit maps of substrate availability. The substrates' availability has been converted into technical potential of advanced biomethane production using specific coefficients. The results indicate a technical potential of advanced biomethane of 5.6 billion m³ in 2022, equivalent to approximately 8 % of Italy's total national natural gas consumption in the same year. This estimate could nearly meet the planned national production targets for 2030 by utilizing only biowaste and residues.

When scholarly classifications focus on the community level, distinctions and interactions between different communities are often subsumed under a broad, general category of \"community,\" thereby inadequately capturing the nuances of inter-community processes. However, managing non-excludable resources effectively usually requires coordinated action both within individual communities and between them; while local-level management is critical for developing context-specific rules, broader inter-community cooperation is essential for addressing trans-community challenges such as ecological interdependence, knowledge sharing, policy alignment, resource mobility, and management scale. While commons scholarship has traditionally emphasized cooperation and rule-making within communities, this paper argues that inter-community governance presents distinct institutional challenges and dynamics-such as coordinating across heterogeneous norms, resolving inter-group tensions, and developing shared governance across different community jurisdictions-that require focused analytical attention. These inter-community dynamics often parallel-and sometimes feed into-national and international negotiation processes, particularly where state policies or transboundary resource regimes intersect with local commons governance. This paper borrows insights from the liberal intergovernmentalism theory in International Relations to introduce an Inter-Community Institutional Framework for analyzing the dynamics of communal collaboration. The framework is applied to forestry and fisheries management on Buvuma Island in Lake Victoria to evaluate perceptions of environmental threats, intra-community interest in collaboration, negotiation processes, and institutional outcomes.
