Summary: This study analyzed the environmental impact and optimization potential of prefabricated components through a life cycle assessment method. It found that a prefabrication rate of 50% and 30% could reduce potential global warming impact by 31.78% and 13.94% respectively. However, the production of prefabricated components in China incurred a social cost of up to $4.35 billion, with Shandong and Hubei provinces being the key areas for optimization.

Summary: This study compares the environmental impacts of alkali-activated concretes containing blast furnace slag, fly ash, and metakaolin with Portland cement concretes. The production processes of the mix constituents and transportation distances are evaluated, and it is found that alkali-activated materials have significantly lower CO2 eq. emissions than PC concretes. Taking into account the variability in production technologies of precursors and activators, alkali-activated materials still have lower CO2 eq. emissions than PC concretes.

Summary: This study assessed the removal of estrone (E1) and 17 alpha-ethinylestradiol (EE2) from synthetic wastewater under anaerobic conditions. The results showed that an increase in temperature favored E1 removal, while EE2 was not affected. Lower mixed liquor suspended solid (MLSS) concentrations promoted higher removal of E1 and EE2. The presence of nitrate did not influence the removal of E1 and EE2.

Summary: The presence of pharmaceuticals in the aquatic environment is a concern, but the effects of these substances under different climate change scenarios are not well understood. This study examined the toxicological impacts of a specific pharmaceutical, 17 alpha-ethinylestradiol (EE2), on edible clams under current and predicted warming scenarios. The results showed that EE2 concentrations disturbed the redox homeostasis of the clams, but the clams were able to activate their defense mechanisms to cope with the stress.

The application of the synthetic photosensitizer (SPS) enhanced the degradation efficiency, and the magnetization procedure allowed for good reusability of the SPS. The effects of the treated water on marine bivalves were evaluated, and the results showed that the SPS treatment effectively decreased the biochemical impacts on the mussels.

Summary: This study evaluated the bioenergy production potential of Halimione portulacoides for the phytoremediation of nutrient-rich simulated wastewater. The study found that the roots and canes of Halimione portulacoides have high carbon content and low ash content, making them suitable for bioenergy production. The nutrient treatments did not have a significant impact on bioenergy production or biomass characteristics. This suggests that Halimione portulacoides can be used as a source of bioenergy in water phytoremediation.

Summary: Pharmaceuticals are frequently found in the environment and can cause harm to human and wildlife as they are able to evade conventional wastewater treatments. This study developed a waste-based magnetic activated carbon (MAC) from paper mill sludge for the adsorptive removal of carbamazepine (CBZ), sulfamethoxazole (SMX), and ibuprofen (IBU) from water and wastewater. The MAC was obtained through electrostatic interactions between magnetic and activated carbon particles. The optimized condition (MACX3) showed excellent properties in terms of surface area and saturation magnetization. Kinetic and equilibrium adsorption studies demonstrated the broad applicability of MACX3 in pharmaceutical adsorption in both ultrapure water and wastewater.

Summary: In this study, a cost-effective chitin-based magnesium oxide (CHt@MgO) biocomposite was developed for efficient removal of anionic methyl orange (MO) dye from water. The CHt@MgO biocomposite was successfully synthesized and characterized. Experimental parameters such as pH, adsorbent amount, contact time, temperature, and initial MO concentration were optimized for MO removal. Langmuir and pseudo-first-order (PFO) models were found to be the most suitable for describing equilibrium and kinetic results, respectively. The CHt@MgO biocomposite exhibited a maximum adsorption capacity of 252 mg/g at 60 degrees C. Reusability tests showed a high removal efficiency of 90.7% after the fifth regeneration cycle.

Summary: A novel polymer bio-composite (CS/n-Hap) consisting of nano-hydroxyapatite (n-Hap) and chitosan (CS) was synthesized for the efficient removal of toxic cadmium ions from water. The CS/n-Hap bio-composite exhibited superior adsorption capacity compared to pristine CS, with a maximum uptake of 126.65 mg/g under optimized conditions. The adsorption mechanism involved the formation of chemical bonds between Cd(II) and CS/n-Hap, as confirmed by the kinetic and thermodynamic studies.

Summary: The efficient removal of antibiotics from wastewater is necessary to prevent their discharge into the aquatic environment and the associated negative effects. An optimized brewery waste-derived activated carbon (AC-SBG) was evaluated for its adsorptive performance in removing three antibiotics from relevant matrix conditions. The results showed that AC-SBG had similar adsorption kinetics to a commercial activated carbon (CAC) and exhibited higher maximum adsorption capacities in ultrapure water. However, in wastewater, the maximum adsorption capacities decreased due to competitive effects. The study also revealed that electrostatic interactions and pH had significant influences on the antibiotics adsorption.

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.
