Summary: This study reports a method to prepare a novel stable CaO-based sorbent by utilizing municipal solid waste incineration (MSWI) bottom ash. The stabilizer derived from the bottom ash promoted the dispersion of CaO and increased the surface area and pore size of the sorbents. The addition of Al2O3 and SiO2 from the bottom ash reacted with CaO to maintain the porous structure of the sorbents. The optimum carbonation temperature for the sorbents was found to be 700 degrees C, and after 20 cycles, the highest CO2 uptake was achieved by the BAS(20 wt%)/CaO sorbent, with a value of 0.14 gCO2/gsorbent.

Summary: The study explored the use of electrodialytic remediation (ED) as a pre-treatment to remove heavy metals from MSWI fly ash before geopolymerization. The pre-treatment increased the reactivity of Si and Si/Al ratio in fly ash. A mixture of 80% coal fly ash and 20% ED treated fly ash with 8 M NaOH was found to have optimal compressive strength in geopolymerization.

Summary: Our society generates a large amount of municipal solid waste (MSW), which is mainly incinerated for volume reduction and energy recovery, but incineration produces hazardous air pollution control (APC) residues that need proper treatment. Material recovery as an alternative to landfilling can reduce hazardous waste amounts and regenerate valuable products. Variations in chemical composition of APC residues within and between incineration plants were investigated, with significant differences found in chemical composition of APC residues from countries other than Sweden and Norway, emphasizing the importance of holistic approaches for waste valorization processes.

Summary: The hazardous waste of municipal solid waste incineration (MSWI) fly ash, which contains dioxins and leachable heavy metals, can be effectively stabilized and reused through microwave hydrothermal treatment with common additives such as Na2S, Na2SiO3, Na2B4O7, or H3BO3. The influence of additive-assisted microwave hydrothermal on heavy metals stabilization was studied at different temperatures, L/S ratios, time, and additive concentrations. The results showed that microwave hydrothermal with Na2S could enhance heavy metals stabilizing by forming zeolites for adsorption, precipitation, and converting heavy metals to a more stable state. This method greatly reduces reaction time and promotes waste utilization.

Summary: In this study, deep eutectic solvents (DESs) functionalized to absorb SO2 at low concentrations were developed as alternatives for flue gas desulfurization (FGD). The prepared DESs showed enhanced thermal stability and multi-site absorption capacity, resulting in remarkable SO2 absorption performance. The absorption mechanism was confirmed through H-1 nuclear magnetic resonance and Fourier Transform Infrared spectroscopy. This study is expected to significantly contribute to alternative technology research on SO2 separation due to the exceptional performance of the proposed absorbents.

Summary: This paper proposes a novel synthesis method for nanosized amorphous CaCO3 based on advanced mineral carbonation using the macromolecular properties of deep eutectic solvents (DESs). CO2 was captured by the DESs-H2O system and converted into particle-size- and morphology-controlled CaCO3. The strength of hydrogen bonding in DES-H2O systems is the primary factor affecting the performance of the solvent.

Summary: NO2 emissions from wall-mounted gas stoves used for household heating have become a significant source of indoor pollution in Chinese urban areas. The high indoor concentration of NO2 poses potential health risks to residents. It is urgently necessary to establish relevant regulations and implement emission reduction technologies to reduce NO2 emissions from wall-mounted gas stoves.

Summary: The objective of this study is to incorporate soil hydraulic properties into the erodibility factor (K) of USLE-type models. By modifying and improving the existing equations for soil texture and permeability, the study successfully included information on saturated hydraulic conductivity (Ksat) into the calculation of K factor. Using the Random Forest machine learning algorithm, two independent K factor maps with different spatial resolutions were generated. The results show that the decrease in K factor values has a positive impact on the modeling of soil erosion rates.

Summary: Atmospheric PM2.5, which can generate reactive oxygen species (ROS), is associated with cardiorespiratory morbidity and mortality. The study found that both the mass concentration of PM2.5 and the DTT activity were higher during the heating season than during the nonheating season. Combustion sources were the primary contributors to DTT activity during the heating season, while secondary formation dominated during the nonheating season. The study also revealed that biomass burning had the highest inherent oxidation potential among all sources investigated.

Summary: This study investigated the presence of aluminum in human colon cancer samples and its potential association with biological processes involved in cancer progression. Aluminum was found in tumor areas of 24% of patients and was associated with epithelial to mesenchymal transition (EMT) and cell death. Additional analyses revealed higher tumor mutational burden and mutations in genes related to EMT and apoptosis in aluminum-positive colon cancers. Understanding the molecular mechanisms of aluminum toxicity may improve strategies for the management of colon cancer patients.
