Summary: Biochar modification by metals and metal oxides has been shown to enhance the adsorption capacity of anionic compounds like phosphate. In this study, paper mill sludge biochar (PMSB) was obtained by pyrolyzing PMS waste containing ferric salt, with PMSB800 showing the best performance for P removal due to the presence of Fe0. The study achieved the conversion of waste PMS into a valuable material with excellent P removal capability and magnetic separation properties through a one-step pyrolysis process.

Summary: Fe-containing sludge can be converted into functional biochar for resource recycling, but the biochar's activating properties are limited by low specific surface area and weak carbon center. Waste expandable polystyrene particles were used to improve the biochar's catalytic performance. The co-prepared biochar achieved high micromesoporous properties, resulting in better iron active sites and oxygen-containing functional groups for wastewater treatment.

Summary: Conversion of sewage sludge to biochar for contaminants removal achieves the goals of solid waste reuse and pollution elimination. However, the understanding of sludge-derived biochar (SDB) for wastewater treatment is still limited. This paper reviews recent studies on the use of (modified) SDB as adsorbents and catalysts for the removal of contaminants from water. It summarizes the effects of modification on the adsorption and catalytic performance of SDB and discusses the challenges and future directions in using SDB for wastewater treatment.

Summary: Modification of biochar using low-cost iron sources is gaining attention. This study produced an iron-biochar composite from incinerated sewage sludge ash (ISSA) and peanut shell, and found that the presence of silica in ISSA affected the properties of the composite, resulting in poorer removal efficiency for As(III) and As(V). However, the composite still exhibited a high adsorption capacity.

Summary: This study evaluated the phenol and lignin removal and enzyme activity in the biological pre-treatment of olive mill solid waste (OMSW) using Anthracophyllum discolor and aquaculture sludge (AS) as an external nitrogen source. The highest removal of lignin and enzymatic activity was achieved in the mixture of OMSW and AS with a C/N ratio of 45. The pre-treatment under these conditions removed 66% of lignin and 68% of phenols in the solid phase, 56% of phenols in the liquid phase, with maximum activities of laccase, manganese peroxidase, and manganese independent peroxidase recorded in 25, 30, and 15 days of pre-treatment, respectively. These findings suggest that incorporating AS as a co-substrate to adjust the C/N ratio allows for increased lignin removal and manganese peroxidase activity, facilitating the treatment of OMSW and AS wastes and the potential recovery of valuable enzymatic extracts.

Summary: This article focuses on the analysis of risks associated with gas transfer operations in an LPG bottling plant in India. Due to urban expansion, these plants are now surrounded by residential and business areas. The frequency of transfer operations has also increased in order to maintain the supply chain. Accidental release of LPG during these operations can have severe consequences such as fire and explosions. The study classifies and analyzes the operations in various hazard zones and models the probability and consequences of accidents using tools like ALOHA and PHAST.

Summary: In this study, ellipsoid-shaped cupric oxide (CuO) nanoparticles were synthesized using a simple hydrothermal method and subsequent heat treatment. The catalysts showed excellent peroxymonosulfate (PMS) activation ability for the degradation of perfluorooctanoic acid (PFOA). Various operating parameters were investigated, and it was found that singlet oxygen (1O2) played a key role in the oxidative-reductive mechanism of PFOA degradation. Additionally, a two-step pseudo-first-order kinetic model was proposed and minimal metal leaching was observed after repeated use.

Summary: A sustainable method using high surface area nanoporous adsorbents synthesized from polycyclic aromatic hydrocarbons (PAHs) effectively removes polycyclic aromatic sulphur heterocycles (PASHs) from fuels. By hypercrosslinking PAHs through a microwave assisted method, nanoporous polymeric materials with high surface area (SABET of 620-1565 m2 g-1) are synthesized. The adsorbent poly-naph (highest SABET, i.e., 1565 m2 g-1) demonstrates excellent desulphurization performance from batch to fixed bed column mode. The adsorption mechanism is attributed to the π-electron density in the polymeric framework and the high surface area. This approach requires technological advancement, financial assistance and governmental regulation to sustain the control of carcinogenic aromatic pollutants.

The variable oxidation states and diverse structures of manganese-based materials have a strong impact on electron transfer reactions. The as-prepared manganese oxides (MnOx) exhibited excellent catalytic activity for the degradation of rhodamine B (RhB) organic pollutant in the presence of peroxymonosulfate (PMS) under acidic conditions. The different oxidation states of MnOx promote oxidative-reductive reactions and the higher surface area provides ample absorption sites for pollutant interactions.

Summary: The size-dependent activity of catalysts has been investigated in catalysis for a long time. Positively charged small Pt clusters exhibit higher catalytic activity compared to larger clusters and bulk for propane dehydrogenation. Computational studies were performed on small Pt clusters adsorbed on silica support, revealing their planar structures and the formation of directional bonds with the support. Ethane and propane molecules undergo dehydrogenation reactions with different activation energies depending on the size of the Pt clusters and the mechanism followed.

Summary: This study investigates the feasibility and mechanisms of a chemical-free nanobubble-based AOP for treating organic micropollutants in water. The results show that the oxygen nanobubble AOP has a significantly higher removal efficiency compared to air and nitrogen nanobubbles. The treatment performance is not affected by pH and the presence of ions. Higher initial concentrations of the micropollutant lead to slower treatment processes, but similar removal performance is achieved in the end. The presence of organic matter reduces the removal rate of the micropollutant. The results have practical feasibility for water and wastewater treatment.
