Summary: This study aims to investigate the factors influencing waste sorting behaviors by using longitudinal data from 945 municipalities in Catalonia from 2000 to 2019. Econometric models are estimated to identify geographic, demographic, socioeconomic, and policy design determinants of sorted municipal solid waste collection (SMSWC) rates at a municipal level. The findings provide new insights on the effects of geographic conditions, unemployment, and foreign population on waste management behaviors, contradicting earlier theoretical expectations. The empirical evidence suggests that active waste collection policies can effectively increase the rate of sorted waste collection to achieve recycling goals set by European Union legislation and the Spanish Waste Law. Additionally, the study emphasizes the importance of considering demographic trends and differences in waste sorting behavior among social groups when addressing waste management issues.

Summary: This study examines how urban financialization is achieved through the use of China's local government bonds (LGBs), with the government relying on debt financing for urban development while regulating to constrain financial risks. The multi-scalar structure of the government strengthens regulations on local development projects and facilitates urban financialization. The government not only facilitates urban financialization through this structure, but also executes statecraft by designing the process.

Summary: The study found that cigarette butts contain various heavy metal pollutants, which can increase heavy metal release when persisting in the environment. Rainfall can accelerate the leaching of heavy metals, leading to higher release rates. It is necessary to reduce the density of cigarette butts in urban and public environments through training and improving the efficiency of urban cleaning systems to prevent heavy metal pollution.

Summary: Heat waves are increasingly severe worldwide, especially in the Mediterranean region. This study focuses on the impact of heat waves in urban areas and the role of urban green infrastructure (UGI) in mitigating their effects. By analyzing land surface temperature (LST) and normalized difference vegetation index (NDVI) data from satellite images, we found stronger negative correlation between LST and NDVI in small green spaces distributed throughout the city. These spaces are crucial in Mediterranean cities where limited space prevents larger UGI elements. Further research is needed to understand how these small green spaces enhance urban cooling given the climate conditions and water scarcity in the region.

Summary: This paper analyzes the urban growth/expansion processes in a medium-sized Brazilian city (Araraquara) resulting from three consecutive periods of master plan implementation. It quantitatively evaluates whether a national market-oriented housing program (MCMV) could explain disparities in spatial outcomes of physical growth associated with different territorial governance arrangements. The findings suggest that while the MCMV program contributes to extensive peri-urban expansion, particularly towards headwater preservation areas that pose social and environmental vulnerabilities in Araraquara, it is not solely responsible for the observed spatial trends after 2009. These results provide insights into how changes in territorial governance arrangements can influence master plan implementation practices.

Summary: The present investigation characterized the distribution and accumulation of microplastics (MPs) in a typical urban river in southwest China. The study found that MPs were present in both surface water and riverine bed sediments, with urban littering and agricultural input identified as major contributors to MP pollution. The discharge of effluent also influenced the distribution of MPs in the urban fluvial system. The study highlighted the negative correlation between MPs abundance and purchase power parity (PPP), indicating the importance of proper waste management in reducing MPs pollution in municipal river systems.

Summary: Urban agriculture activities are becoming more popular and important due to increased food demands and reduced agricultural land. The recovery of nutrients from waste sources in urban areas can enhance circularity, self-sufficiency, and reduce environmental costs. This study identifies various strategies for nutrient recovery and assesses their potential to meet the nutrient demands of urban agriculture in Barcelona. The results show that while the current perception, legislation, and costs hinder the implementation of nutrient recovery strategies, they hold promise for the future.

Summary: The study found intense awareness and legislative support in Slovenia for Industrial Symbiosis (IS) and Urban Symbiosis (UrS), in line with EU regulations. However, there has been surprisingly little waste-to-energy recovery since 2010. Reuse of by-products for energy or new products is almost non-existent. Urban strategies in Slovenia are insufficient in providing concrete guidelines for the development of IS and/or UrS.

Summary: This study examines the relationship between formal and informal recycling sectors in Catalonia by analyzing data collected from informal recyclers. It was found that informal recyclers had the potential to collect a significant amount of cardboard in their geographic area, contributing to environmental goals but lacking recognition. Furthermore, the study highlights the impact of global waste markets on both formal and informal systems, suggesting a complex interplay between the two.

Summary: This study developed an agent-based model to estimate the total volume of demolition waste and the amount of waste generated at each disposal stage in Shenzhen, China, revealing the greater potential of deconstruction method in reducing waste generation. However, the change in attitude towards demolition method is slow, and reliance on demolition companies' attitude change alone is insufficient for improving waste management performance. An optimized management framework involving related stakeholders is needed for better waste management.

Summary: Due to complex interactions between climate and land use changes, large forest fires have increased in frequency and severity. In southern European countries affected by demographic challenges, fire risk and danger are particularly relevant at the wildland-urban interfaces (WUIs). This study aims to develop a comprehensive scheme for identifying WUI typologies most at risk to fire severity and found that isolated, scattered, and sparsely clustered buildings in a high-cover shrub matrix are the most susceptible to high-severity fires.

Summary: This study analyzes the characteristics of process parameters in three lean gas ethane recovery processes and establishes a prediction and multiobjective optimization model for ethane recovery and system energy consumption. A new method for comparing ethane recovery processes for lean gas is proposed, and the addition of extra coolers improves the ethane recovery. The support vector regression model based on grey wolf optimization demonstrates the highest prediction accuracy, and the multiobjective multiverse optimization algorithm shows the best optimization performance and diversity in the solutions.

Summary: The paper proposes a novel deep learning-based prediction framework, aTCN-LSTM, for accurate cooling load predictions. The framework utilizes a gate-controlled multi-head temporal convolutional network and a sparse probabilistic self-attention mechanism with a bidirectional long short-term memory network to capture both temporal and long-term dependencies in the cooling load sequences. Experimental results demonstrate the effectiveness and superiority of the proposed method, which can serve as an effective guide for HVAC chiller scheduling and demand management initiatives.

Summary: This study uses survey data from the Loess Plateau in China to evaluate the impact of social interaction on the adoption of soil and water conservation (SWC) technology by farmers. The study finds that social interaction increases the likelihood of farmers adopting SWC, and internet use moderates this effect. The positive impact of social interaction on SWC adoption is more pronounced for farmers in larger villages and those who join cooperative societies.
