Summary: Environmentally persistent free radicals (EPFRs) are emerging contaminants formed during thermochemical processes. This study investigated their formations in fly ash and biochar and found that EPFRs are closely related to precursor and temperature. The pyrolysis temperature and residence time significantly impacted the types and concentrations of EPFRs in resulting biochar.

Summary: The study found that the efficiency of phosphorus extraction from sewage sludge ash varied with different incineration temperatures, while for acidic extraction liquids, the optimal P extraction efficiency was found in samples obtained around 850 degrees Celsius. Co-extraction of heavy metals generally decreased with increasing incineration temperature, possibly due to the immobilization of heavy metals in the SSA matrix.

Summary: The research found that in soils where nTiO(2) was applied after incineration, the added titanium dioxide may be significantly mobilisable and have high mobility. The standard column leaching experiment may be used to indicate the increased mobility of nTiO(2) in soils, but further soil experiments are needed to validate these findings.

Summary: With the growing emphasis on environmental protection, this review analyses different methods of sewage sludge treatment in terms of potential environmental risk and raw materials recovery. The study suggests that direct use of sewage sludge in agriculture should no longer be considered as a source of nutrients and organic matter due to its pollutant content. The review also highlights pyrolysis as a sustainable method for sludge treatment in remote locations with low heavy metal content, and discusses different technologies for recovering phosphorus from sludge ash.

Summary: Thermal plasma treatment is a promising method for fly ash disposal. Experimental results show that the formation temperature of vitrified slag can be reduced during co-treatment, and the CaO content in raw materials is related to the volatilization of Cd and Pb. A high Al2O3 content is beneficial for retaining Cr, Cu, and Ni in slags.

Summary: Thermal treatment of sewage sludge has gained significant attention in recent years. Numerous papers have discussed the mass flows, energy, and emissions data related to incineration, gasification, and pyrolysis of sewage sludge. Incineration is an established technology, but there is limited data on flue gas cleaning and air emissions. Gasification and pyrolysis are experimental technologies with varying output data.

Summary: A high-temperature slagging gasifier was used to co-treat sludge-based waste materials with municipal solid waste (MSW), resulting in successful co-gasification and recovery of reusable slag and recyclable metals. The stable operation of the gasifier was achieved through proper control of temperature profiles, melting of inorganic residues, smooth discharge of molten slag, and effective flue gas emissions control. The waste-derived slag was found to be environmentally safe and showed potential as sustainable construction materials, as indicated by toxicity tests and life cycle assessment.

Summary: The phase of the ZrO2 support has a significant influence on the nature and formation rates of surface species during methanol synthesis from CO2 hydrogenation. The m-ZrO2:In catalyst exhibits higher activity, with faster formation of formate and methoxy species. Only formate species are detected on t-ZrO2 and am-ZrO2 catalysts, while methoxy and formate species are found on m-ZrO2:In and In2O3/am-ZrO2, respectively. In contrast, only a weak formate peak is observed on In2O3/t-ZrO2 catalyst. The presence of an india-zirconia interface is crucial for the effective stabilization of formate species in unsupported In2O3.

Summary: The proposed debris flow model divides the muddy fluid into two parts, one bonded to solid particles forming the first layer, and the other moving independently forming the second layer. Shearing of rocky particulate material during flow induces dilatant motions, changing the solid center-of-mass position. The model is able to capture the streamwise evolution of debris flow density in time and space.

Summary: As the importance of fecal sludge management (FSM) is increasingly recognized, the need for well-designed and functioning fecal sludge (FS) treatment plants is growing. This study evaluated the impact of extracellular polymeric substances (EPS) on the dewaterability of FS, and how EPS and dewaterability change during anaerobic storage. The results showed that an increase in EPS decreased the dewaterability of FS. Furthermore, the study found that anaerobic storage time does not predict the dewaterability of FS.

Summary: Thanks to intense research efforts, modern low-energy buildings have significantly reduced their space heating loads compared to older buildings. However, further reduction of energy consumption requires optimization of domestic hot water systems. This study argues that a multi-scale, multi-disciplinary mindset is essential for finding sustainable solutions in this area, and highlights the importance of collaboration and knowledge integration between urban water specialists and building engineers.

Summary: Establishing generic catalyst design principles by identifying structural features of materials that influence their performance will advance the rational engineering of new catalytic materials. This study investigates the activity of metal-substituted manganese oxide (spinel) nanoparticles for the electrocatalytic oxygen reduction reaction (ORR) and rationalizes it based on the enthalpy of formation of the binary MO oxide, ΔH-f degrees(MO), and the Lewis acidity of the M2+ substituent. The incorporation of elements M with low ΔH-f degrees(MO) enhances the oxygen binding strength in Mn3O4:M, which affects its activity in ORR. Our work provides insights into the design of new compositions for oxygen electrocatalysis using rational substitution/doping by redox-inactive elements.

Summary: In this study, the ability of five commercially available online sensors to predict the microbial water quality in membrane bioreactors followed by chlorination was tested. It was found that free chlorine and oxidation-reduction potential could predict the microbial water quality well, with oxidation-reduction potential-based models performing better. A methodology to link online sensor measurements to risk-based water quality targets and provide operation setpoints protective of human health for specific combinations of wastewaters and reuse applications was proposed.

Summary: The oxidative dehydrogenation of propane can occur through a gas-solid interface or in the gas phase via a radical chain process. This study found that an empty quartz reactor can achieve high propene and ethene selectivities and propane conversions comparable to those of state-of-the-art ODP catalysts. Optimizing the post-catalytic volume of a h-BN catalyst bed can increase propane conversion and propene selectivity, indicating it as an important variable for improving catalytic ODP performances.

Summary: In this study, the underlying cause of the increase in oxygen release rate of an oxygen carrier during redox cycling was elucidated. The removal of surface carbonates was found to be the main factor behind this activation phenomenon. Furthermore, the re-formation of surface carbonates after exposure to CO2 resulted in the deactivation of the perovskite oxygen carrier. These findings are important for the performance of such materials in chemical looping at relatively low temperatures (<= 500 degrees C).

Summary: Chemical looping is a promising technology for producing high purity hydrogen while capturing CO2. This study investigates the addition of sodium in the synthesis of Fe2O3-Al2O3 oxygen carriers to counteract cyclic deactivation. The addition of sodium prevents the formation of FeAl2O4 and stabilizes the oxygen carrier, resulting in a stable hydrogen yield.

Summary: Microplastic contamination in marine ecosystems poses a growing concern due to its trophic transfer and negative effects on marine organisms. This study investigates the transfer and impacts of polystyrene microplastics in an estuarine food chain. The results show that microplastics can be transferred through the food chain, although the transfer rates are low. The exposed organisms exhibit stress responses, suggesting the potential risk of microplastics reaching humans through the food chain.

Summary: This study measured the levels of phthalate metabolites in breast milk collected from mothers in southern China. The results showed that phthalates are still prevalent in the region, and breastfeeding contributes to phthalate intake in infants. However, the levels detected do not pose significant health risks to infants based on dietary exposure. The increasing exposure to certain phthalates calls for further research into their sources and potential risks.
