Summary: In this study, wastewater post-coagulation sludge (WPCS) was converted into functional char using abundant amounts of Al/Fe (hydr)oxides. The resulting char showed higher specific surface area, stronger aromaticity, and more amorphous Al and Fe contents. The WPCS char under CO2 demonstrated superior performance for removing phosphate, heavy metals, and dyes. This study proposes a win-win strategy for converting coagulation sludges into resources and producing multifunctional adsorbents.

Summary: Algae can be used to produce valuable compounds and biofuels, and their waste can also be converted into biofuel, biogas, and biochar through different thermochemical processes. Algal biochar carbonized at high temperatures shows excellent performance in applications such as CO2 adsorption and energy storage. Algae biomass pyrolysis at moderate and low temperatures can produce high-quality biochar and coal fuel, respectively. In addition, algae-based biopolymers are considered a potential alternative for establishing a sustainable circular economy globally due to their composting capacity, rapid growth ability, and greenhouse gas emission reduction.

Summary: Emerging contaminants (ECs) such as pesticides, PAHs, dioxins, personal care products, cosmetics, and medications are found in alarming amounts in groundwater, surface water, and wastewater due to the strong demand and growth of these industries. Conventional wastewater treatment techniques show some removal performance, but emerging AOPs, especially activated persulfate oxidation, have gained attention for their outstanding performance in ECs remediation. This article provides a critical review of electro, sono, and thermal activation of persulfate for ECs treatment, discussing key parameters and reaction mechanism. Recent experiments demonstrate high removal efficiency using persulfate in electro, sono, and thermal activation, emphasizing the negative impact of ECs on the environment.

Summary: Municipal solid waste management is a key issue in developing countries like Palestine, and waste-to-energy technology is an effective strategy. A study in Palestine's Tulkarm area evaluated different approaches for energy recovery from municipal solid waste. Anaerobic digestion was found to be the most environmentally advantageous and economically feasible solution, recovering 5156.15 kWh per day and saving about 48,362 tons of CO2 annually. Incineration and gasification also showed significant energy recovery and emission reduction capabilities. Evaluation of energy cost savings showed incineration to have the highest savings at USD 4918.12, while anaerobic digestion had savings of USD 618.74.

Summary: Thermal remediation technologies are effective tools for remediating contaminated soils and sediments, but their wide application is hindered by high energy consumption and the adverse effects of high temperature on soil properties. This review discusses eight types of thermal remediation processes and their combination with other remediation technologies. The sustainability of thermal remediation is evaluated in terms of energy efficiency and its impact on soil properties. Continued research on thermally based technologies is expected to increase their sustainability and expand their applications. Low temperature thermal desorption is identified as a promising remediation technology with minimal adverse effects on soil function. The selection of a sustainable remediation technology depends on the characteristics of the contaminants, soil properties, and predicted risk level.
