Summary: Carbonation of recycled concrete paste has the potential to reduce CO2 emissions in the cement industry by sequestering CO2 and using the carbonated material in new composite cements. This study investigates the effects of wet and semi-dry carbonation on the hydration reactions and performance of composite cements incorporating the carbonated material. The carbonation methods result in differences in composition and morphology of the carbonated paste, but the effects on cement performance are primarily influenced by the carbonation degree of the recycled concrete paste.

Summary: This study investigates techniques to improve the quality of recycled aggregates, such as removing mortar particles and surface modification. The results show that mechanical grinding and a two-stage mixing method can improve the properties of the recycled aggregates. The test results indicate that these methods enhance the compressive strength and tensile strength of concrete. Therefore, the use of these treatments can improve the mechanical properties and durability of concrete produced by recycled aggregates.

Summary: The study explores the mechanical and durability performance of recycled aggregate concrete (RAC) made with different types of wastewater. Results show that RAC made with textile factory wastewater has the highest compressive strength and split tensile strength, while RAC made with domestic sewerage wastewater has the highest water absorption rate. The use of fertilizer factory wastewater leads to the highest mass loss and chloride penetration in RAC production.

Summary: This paper presents a new method for Fenton treatment of complex wastewater using a novel bioelectrode system. The new system eliminates the need for additional dosing of Fe(II) and H2O2, prevents iron-sludge accumulation, and reduces consumption of pH regulators. The experimental results demonstrate that the method is efficient in removing dissolved organic carbon and specific recalcitrant organics.

Summary: Sustainable food waste management is crucial for improving food security and conserving natural resources and ecosystems. Diverting food waste from solid waste to wastewater stream allows for separation, collection, treatment, and disposal, while also recovering water, resources, and energy. Extensive studies have been conducted to evaluate the feasibility and impacts of food waste diversion on solid waste and wastewater systems. The review identifies challenges and discusses the contribution of food waste diversion to urban sustainability.

Summary: Sustainable effluent treatments are crucial for reducing the environmental impact of industrial activities. Plant-based coagulants, with their higher biodegradability, non-toxicity, and lower cost, can effectively replace synthetic coagulants in effluent treatment. This review focuses on the application of plant-based coagulants in food industry wastewater treatment, providing extraction parameters and treatment conditions for different coagulants. It compares the performance of plant-based coagulants to traditional, synthetic coagulants, both alone and as coagulant aids, based on a comprehensive assessment of peer-reviewed papers. The goal of this review is to guide researchers and industry professionals in optimizing and scaling up environment-friendly wastewater treatments using natural coagulants.

Summary: The autopsy of carbon-PTFE cathodes in a plate-and-frame cell with a Nb-BDD anode revealed a significant decrease in H2O2 electrogeneration, hindering the efficient performance of Fenton-like processes. The study found that the first cathode suffered surface degradation, while the second cathode had iron oxide inlays due to the decomposition of Fe3+:EDDS and iron precipitation at neutral pH.

Summary: The study examined the potential of Photocatalytic Membrane Reactor (PMR) technology for nitrate removal from drinking water with organic electron donors. Formic acid was found to be the most effective hole scavenger, followed by acetic acid and humic acid. The PMR system showed superior performance in nitrate reduction and total organic carbon percentage removal. Further research is needed to optimize the process for improved efficiency.

Summary: Phytoremediation is an emerging concept for restoring contaminated soil using resilient plants. The contaminated biomass can be converted to energy carriers/chemicals through thermochemical processes such as Supercritical Water Gasification and Fast Pyrolysis. Purification technologies, including membrane gas absorption, electrooxidation/electrocoagulation, and microfiltration, are crucial for the successful integration of these conversion processes. Challenges, risks, and suitable strategies for implementing these purification technologies in the context of biomass-to-energy conversion are discussed.

Summary: Electrodialysis is a promising technique for the separation of important ions in industrial effluents. However, there is limited research on the simultaneous removal of lead and sulfate ions. This study investigates the removal of lead and sulfate ions at industrially relevant concentrations using a pilot-scale electrodialysis setup. The optimized conditions for sulfate ion removal were applied for simultaneous removal of lead and sulfate ions, achieving high removal rates with an energy consumption of 7 kWh/m3.
