Summary: This study investigated the degradation of petroleum hydrocarbons in soil using FeS@BC and FeS activated persulfate (PS). The results showed that the FeS@BC/PS system had a higher removal rate for total petroleum hydrocarbons, polycyclic aromatic hydrocarbons, and n-alkanes compared to the FeS/PS system. Radical quenching experiment and Electron Paramagnetic Resonance revealed that the dominant active substance is sulfate free radical produced by PS during activation. The FeS@BC/PS system has great potential for the remediation of petroleum-contaminated soil.

Summary: In this study, a pilot-scale hybrid treatment system consisting of HC, HS, and PS was used to remove PAHs from dredged harbor sediments. The study found that under certain conditions, the combined HC-PS-HS system can effectively remove PAHs, especially lower-ring PAHs. Additionally, the decline in organic matter content during the combined treatment process was found to lead to the gradual degradation and transformation of aromatic protein-based components into soluble microbial metabolites.

Summary: In this study, a novel strategy was proposed and proven to enhance the delivery of persulfate (PS) to soil by electrokinetics (EK). The application of pulsed direct current (DC) electric field thermally activated the PS in situ, promoted PS plume mixing and contaminants-free radicals reaction, and replenished PS to achieve efficient degradation of contaminants in low permeability zones. The results showed that EK transport rate of PS in soil was 12.3 times higher than diffusion. Irregular pulsed DC field maintained the targeted temperature during activation phase, resulting in the generation of oxidative radicals (SO·4/·OH). Electromigration and electroosmosis also promoted PS transport and reactive mixing, enhancing the degradation of polycyclic aromatic hydrocarbons (PAHs) contaminated soil. PS concentrations in pore fluid increased with continuous fluctuations. Long-term low-temperature activation led to a significant decrease (nearly 60%) in average concentration of PAHs in the whole soil cell over 10 days. These findings demonstrate the great potentiality of the novel strategy in remediating low permeability contaminated soil.

Summary: Biochar is proposed as an innovative and sustainable technology for remediation of PAH-contaminated sediments, mainly through sorption mechanisms. The use of biochar can significantly improve the efficiency of PAH removal from sediments, especially when used in combination with multi-PAH systems and high dosages. Additionally, biochar has shown to decrease PAH degradation during bioaugmentation and phytoremediation of sediments, but can increase degradation when used with nitrate as an electron acceptor in low-temperature conditions.

Summary: Here, a facile and selective synthesis of cationic azatriphenylene derivatives was achieved through electrochemical intramolecular cyclization, where the key step involves atom-economical C-H pyridination without a transition-metal catalyst or an oxidant. This proposed strategy provides a practical approach for introducing cationic nitrogen (N (+)) into pi-electron systems, thus expanding the molecular design of N (+)-doped polycyclic aromatic hydrocarbons.

Summary: In this study, CeO2-based porous carbonaceous frameworks (CeO2 PCFs) were used as antioxidant nanozymes to scavenge reactive oxygen species and absorb benzo[a]pyrene. CeO2 PCFs exhibited excellent superoxide dismutase-like and catalase-like activity, effectively eliminating superoxide radical, hydroxyl radical, and hydrogen peroxide. The 2,2'-azino-bis(3-ethylbenzthiazoline-6-sulfonic acid) free radical scavenging assay confirmed the free radical scavenging ability of CeO2 PCFs. Furthermore, CeO2 PCFs with large surface area and porous structure efficiently adsorbed benzo[a]pyrene. The designed CeO2 PCFs can serve as new antioxidant nanozymes for scavenging reactive oxygen species and adsorbing polycyclic aromatic hydrocarbons (PAHs).

Summary: This study presents an efficient method for remediating DEHP-contaminated marine sediments using water hyacinth biochar (WHBC) as a carbocatalyst activated by calcium peroxide (CP). The catalytic capacity of WHBC was significantly influenced by the pyrolysis temperature. The WHBC/CP system achieved a 94% removal of DEHP, with singlet oxygen (1O2) and electron-rich carbonyl functional groups playing crucial roles in the non-radical activation of CP. Moreover, WHBC showed lower cytotoxicity in HepG2 cells and induced cell cycle arrest at the G2/M phase.

Summary: This study synthesized a novel material, dual heteroatom nitrogen and boron-co-doped lignin-based biochar (NB-LGBC), which was used for the activation of calcium peroxide (CP) to enhance the removal of organic micropollutants (OMPs), such as 4-nonylphenol (4-NP), from waste activated sludge (WAS). The introduction of NB-LGBC/CP significantly improved the degradation of 4-NP through a synergistic interaction and electron transfer. Furthermore, the NB-LGBC/CP treatment enriched specific bacteria, Desulfonatronum within the Proteobacteria phylum, in the WAS, enhancing the biological treatment capacity of 4-NP. Therefore, NB-LGBC shows great potential as a novel approach for decontamination of WAS.

Summary: Biorefinery is a promising alternative to petrorefinery for sustainable development, with lignocellulosic biomasses as the most important raw material. Enzymatic conversion of biomasses into bioethanol is considered the most sustainable method, but biomass recalcitrance presents a major challenge. Pretreatment targeting lignin, the main contributor to recalcitrance, is necessary to make cellulose and hemicellulose more accessible to enzymes. Laccase, a lignin-degrading enzyme, is a potential option for biological pretreatment, although its slow reaction rate is a limitation. This article provides insights into biorefinery and emphasizes the significance of laccase.

Summary: Bioactive peptides derived from fish byproduct protein hydrolysate have vast potential as functional food ingredients. Enzymatic hydrolysis is the preferred method for the preparation of these peptides due to its high specificity, mild reaction conditions, and lack of residual organic solvents. However, the use of proteases and the availability of food-grade enzymes pose limitations. Current research focuses on the purification and identification of these peptides, as well as their bioactivities, including antiproliferative, antimicrobial, antihypertensive, antiglycemic, antitumor, and antioxidative functions. The growing interest in proteomics and the utilization of marine and aquatic waste stems from the bioactivity and sustainability of these products.

Summary: The effect of pyrolysis atmosphere (CO2 or N2), pyrolysis temperature (300-900 degrees C), and heteroatom (N, B, O, P, NP, or NS) doping on the content of polycyclic aromatic hydrocarbons in pineapple leaf biochar was investigated. Without doping, the highest polycyclic aromatic hydrocarbon production (1332 +/- 27 ng/g) was observed in CO2 at 300 degrees C, while the lowest (157 +/- 2 ng/g) was observed in N2 at 700 degrees C. The main components, naphthalene and acenaphthylene, accounted for about 91% of the total polycyclic aromatic hydrocarbon in biochar produced under CO2 at 300 degrees C. Doping significantly reduced the total hydrocarbon content, with reductions of 49% (N), 61% (B), 73% (O), 92% (P), 93% (NB), and 96% (NS) under the conditions of maximal polycyclic aromatic hydrocarbon production (CO2, 300 degrees C). The findings highlight the importance of controlling pyrolysis atmosphere, temperature, and heteroatom doping for the management of polycyclic aromatic hydrocarbons in biochar production and contribute to the development of circular bioeconomy.

Summary: The increasing concerns about climate change and the overexploitation of non-renewable resources have led to the need for alternative renewable and eco-friendly resources for the production of innovative materials, achieving the goals of bioeconomy. Lignocellulosic biomass (LB), derived from plant-based agro-industrial food waste and crop residues, can be utilized for the production of various value-added chemicals and bioproducts. Cellulose, derived from LB, is the most abundant natural and biodegradable organic polymer, with wide-ranging applications in lignocellulosic biorefineries and food industries. However, the extraction of cellulose from LB is challenging due to the recalcitrant nature of biomass. A suitable cellulose extraction method through LB fractionation is necessary to improve cellulose yield. Nanocellulose (NC) has great potential and researchers are interested in developing environmentally friendly cellulose extraction methods. Cellulose nanofibrils and nanocrystals have excellent mechanical properties, non-toxic characteristics, and biodegradability, making them suitable for diverse industrial sectors. This review emphasizes the potential role of cellulose extraction and NC production from agro-food waste, discusses different pretreatment methods for cellulose extraction from LB, and highlights the applications and future directions of cellulose and NC-based commercial products.
