Summary: The study evaluates the current and alternative MSW paths in Mexico City to compare their performance in terms of fossil energy use, GHG emissions, resource recovery, and economic cost, aiming to identify more sustainable practices. The current MSW path in Mexico City is unsustainable due to heavy reliance on landfilling, large GHG emissions, and low MSW valorization, while incineration-based paths perform better in most aspects but are hindered by high costs. The results suggest that MSW paths featuring open windrow composting, mechanical-biological pretreatment, material recovery facilities, and refuse-derived fuel production may be more appropriate for improving the sustainability of MSW management in Mexico City.

Summary: This paper examines the extent to which urban dwellers' everyday life can be explained by the visual clues of the urban environment. By analyzing 27 million street view images across 80 counties in the United States, the study shows that urban features captured from street view images can significantly predict travel behavior, poverty status, crime, and health behaviors. The explanatory power of these urban features exceeds that of models based on points of interest, population, and other demographic data alone.

Summary: Street bin litter (SBL) is a neglected waste stream that lacks in-depth research on its composition. Through five sorting experiments on SBL collected in Leuven, Belgium, it was found that the major fractions of SBL include illegally dumped waste (33 +/- 3%), organics (17 +/- 4%), and paper and cardboard (16 +/- 2%). On a functional level, approximately 35% of SBL consists of packaging, with beverage and food packaging constituting significant portions. Although economically viable material recovery may not be feasible, SBL cannot be ignored due to its visibility. Implementation of preventive measures and Extended Producer Responsibility schemes can effectively reduce SBL.

Summary: Urban extractivism refers to the destructive impact of large-scale natural resource extraction on urban environments and societies. It is a concept that is increasingly discussed in Latin American scholarship but less known in anglophone urban geography. Currently, the concept is mainly applied to study the social and environmental consequences of infrastructure megaprojects accompanying resource extraction. However, scholars are also exploring the usage of this concept to analyze the production of exclusive urban territories in central Buenos Aires. The author suggests broadening the concept of urban extractivism to address urgent challenges of urban transformations in the peripheries of Mexico City, particularly concerning urban infrastructure megaprojects and Indigenous socio-territorial movements advocating for a more sustainable use of natural resources.

Summary: The surface heating in complex urban areas affects the concentration of secondary inorganic aerosol (SIA) through flow and chemical environment changes. Previous studies have mainly focused on the effect of dispersion change caused by heating. However, the heating of buildings also affects SIA concentration through chemical environmental changes, such as changes in reaction rate and thermodynamic equilibrium. In this study, we used a coupled chemistry-computational fluid dynamics (CFD) model to investigate the effects of heating, considering both flow changes and chemical environment changes, on SIA. Our findings show that both the chemical and dynamical effects reduce SIA concentration. The effect of heating caused by chemical environment changes is 49.4% larger than that of flow changes, highlighting the importance of considering chemical reactions in aerosol calculations in urban microscale simulations.

Summary: The development of controlled-release fertilizer formulation is important for preventing environmental pollution caused by nutrient leaching and volatilization. This study combined biochar-based fertilizer with encapsulation technology to improve the nutrient release mechanism. Optimal conditions for synthesizing urea-impregnated biochar (UIB) were determined using central composite design, and the release of nitrogen was described by mathematical models. Results showed that encapsulated UIB (EUIB) achieved complete release of nitrogen in water and exhibited improved water retention in sandy-textural soil. Therefore, EUIB derived from peppercorn waste has the potential to be used as a sustainable controlled-release fertilizer for agriculture.
