Summary: Hydrothermal carbonization (HTC) is an efficient method to convert wet food waste into hydrochar. However, the by-product of this process, HTC wastewater, contains highly polluting chemicals. In this study, hydrochar was produced through HTC process and further processed into activated carbon (AC) using KOH activation. The obtained AC was used to catalyze the degradation of HTC wastewater. The optimal condition for the catalytic process was determined, achieving a COD removal efficiency of 78.94%.

Summary: The study found that cooking treatment enhanced the formation of mesopores in the activated carbon (AC), but decreased the overall yields of bio-oil and gases. HTC pretreatment decreased the production of AC and gases, but remarkably enhanced bio-oil formation. Pyrolysis increased the aromatization degree of biochar and produced the highest overall yields of AC.

Summary: This research conducted a calorimetric evaluation of activated carbon-type adsorbent solids prepared by chemical activation of African palm shells with Fe(NO3)(3) and Cu(NO3)(2) salts. The immersion enthalpy values of porous materials varied with different immersion liquids, chemical agents, and concentrations. The BET areas and pore volumes of the obtained adsorbent solids increased proportionally to the increase in immersion enthalpy values, showing variations in textural and chemical characteristics of porous solids.

Summary: Developing monolithic electrodes with high capacitor performance using chemically activated commercial melamine sponges and KOH is a challenge in the energy storage field. The study demonstrates that adjusting the KOH/melamine sponge mass ratio can regulate the graphitization degree, heteroatom content, and pore size distribution of the monolithic N-/O-doped carbon sponge electrodes. The optimized electrode shows promising specific capacitances and retention rates, and the charge storage mechanism in NOCSs is systematically studied to separate different capacitance contributions. Additionally, the NOCSs show good capacitance performances in all-solid-state supercapacitors, providing high energy density and power output for driving LED devices.

Summary: Chicory roots are a low-cost agricultural residue that can be used as a feedstock for producing 5-Hydroxymethylfurfural (HMF). In this study, two methods were investigated to increase the fructose content in the extracted inulin and fructose from chicory roots. The first method involved acid-assisted extraction, while the second method involved aqueous extraction followed by nitric acid hydrolysis. It was found that separating extraction and hydrolysis was more suitable for integrating this process into a biorefinery concept for HMF production.

Summary: This study evaluates the performance of ozonation and adsorption as in-series processes compared to standalone processes for the removal of Contaminants of Emerging Concern (CECs) in drinking water. The combination of both processes proves to be more effective than adsorption and ozonation alone. Ozonation improves the adsorption performance of poorly-oxidizable CECs but worsens that of well-oxidizable compounds. This research highlights the importance of considering both processes in the removal of CECs in drinking water treatment plants.

Summary: The exacerbation of global warming, extreme weather events, and rapid urbanization have led to increased flooding in urban areas. China has adopted sponge city as an efficient means of preventing and controlling urban floods. Using a SWMM-FVCOM model, the hydrological reduction and control effect of sponge city construction (SPCC) within a university campus were evaluated. The study found that implementing SPCC effectively mitigates surface runoff and reduces the severity of urban flooding. However, the efficacy of runoff control decreases with longer rainfall return periods.
