Summary: Sustainable fuels are crucial for industries that cannot be easily electrified. Processing wet solids through hydrothermal liquifaction to produce upgradeable bio-oil is a promising pathway for transforming high moisture waste into fuel. The viscosity of slurry-based conversion processes can be significantly improved by natural biological degradation and torrefaction. Physical and chemical parameters such as particle size, shear rate, and extractives content have been shown to impact slurry viscosity and processability.

Summary: The rigid cell wall of algal biomass restricts the availability of soluble organics, reducing the efficiency of biofuel production. Various pretreatment methods can enhance cell wall disintegration and biofuel generation. The potential of pretreatment methods depends on biomass liquefaction, energy, and cost demand. This review discusses different pretreatments and their efficiency in enhancing liquefaction and biofuel yield for pilot-scale implementation. Combining and phase-separated pretreatments show great potential in enhancing biofuel generation based on liquefaction potential, energy, and cost. Future studies should focus on reducing the cost and energy requirement of pretreatment.

Summary: Aqueous phase (AP) recirculation is a promising method to enhance biocrude production and alleviate the environmental impacts of AP discharges. Isothermal and fast hydrothermal liquefaction (HTL) experiments were conducted with different mixing ratios of water and AP products. The results showed that the optimum mixing ratio of 2:4 resulted in the highest biocrude yield. Nitrogen heterocycles and amides were found to be the major compounds in biocrude and AP, contributing to biocrude generation. AP recirculation for three times can significantly reduce wastewater discharges.

Summary: Combining torrefaction with fast pyrolysis is a feasible method for producing long-chain ether precursors. Structural characterization results showed that torrefaction led to a decrease in crystallinity index and the elimination of hydroxyls, ether bonds, etc., but an increase in carbonyls. The production of small-molecule gases was reduced after torrefaction, while the yield of targeted compounds in bio-oil significantly improved, with 240CS providing the highest carbon yield.

Summary: The potential valorisation of wastewater containing phenolic compounds obtained from the hydrothermal liquefaction of Kraft black liquor was analysed for the first time. Hydrophobic eutectic solvents were used to recover the phenolic compounds with high yields and selectivity. The best solvent was found to be a menthol:octanoic acid combination, which showed excellent performance in terms of recovery and selectivity. The results obtained open up possibilities for the simultaneous valorisation of the extract and raffinate.

Summary: This study investigated the use of waste aqueous phase from hydrothermal sludge treatment for cultivating the microalgae Chlorella sp. The results showed that the waste aqueous phase can serve as a suitable medium for Chlorella sp, with a nitrogen and phosphorus removal efficiency of over 90%. It was also found that the addition of CO2 during microalgal cultivation can enhance the growth of Chlorella sp and increase lipid content. Optimal cultivation conditions were determined as 5% CO2, BG-11/SAP = 1:1 mixed medium, and a cultivation period of 8 days. Furthermore, a comparison was made between the bio-oil and aqueous phase obtained from fast hydrothermal liquefaction and regular hydrothermal liquefaction.

Summary: Interactions between cold atmospheric-pressure plasma jets and water are crucial for various applications including water purification, chemical synthesis, medicine, and biotechnology. This study compared the reactivity and bactericidal effects of water activated by plasma jets with different ionized gases, particularly helium (He) and argon (Ar). The experimental results showed that the Ar plasma jet had a faster propagation velocity, higher concentrations of reactive species, and better bacterial inactivation effects compared to the He plasma jet. The deformation of water induced by the plasma was identified as the reason for the differences in reactivity and bactericidal effects.

Summary: Current industrial nitrogen fixation technology relies on fossil fuels and has negative environmental impacts, but using electricity-driven non-thermal plasma catalysis shows promise for sustainable nitrogen fixation. This study combines a structured catalyst with a water-electrode bubble reactor to fix nitrogen at ambient conditions with high selectivity and stability. The enhanced production of nitrate ions is attributed to abundant oxidized nitrogen species from the air plasma, with the TiO2 supported by graphene oxide playing a crucial role in improving nitric oxide surface association and minimizing backward dissociation. These findings advance the potential of plasma-catalyzed nitrogen fixation for clean energy and eco-friendly chemical production.

Summary: Plasma activated saline solution (PAS) has great potential in various applications such as sterilization, water treatment, wound healing, and cancer treatment. However, the role of reactive chlorine species (RCS) in PAS has been less studied. In this research, the formation mechanism of RCS in O-treated saline was investigated, and the effect of chlorine and oxygen concentration was explored. The results showed that the presence of chlorine, oxygen radicals, and solution pH were important factors in the production of RCS. The study also demonstrated the anticancer effects of PAS by biological inactivation functions.

Summary: Inspired by biological photosynthesis, developing effective strategies to up-cycle anthropogenic carbon dioxide (CO2) into high-value organics is crucial. In this study, mesoporous indium supported on multi-walled carbon nanotubes (mp-In@MWCNTs) was synthesized via a facile wet chemical method and exhibited high performance in electrochemical CO2 reduction reaction (CO2RR) for formate production. The unique structures of mp-In@MWCNTs with mesoporous surfaces and a conductive network were found to promote both adsorption and desorption of reactants and intermediates, improving electron transfer and leading to outstanding CO2RR performance.

Summary: This study investigated the impact of the non-antibiotic pharmaceutical carbamazepine on antibiotic resistance genes (ARGs) during anaerobic digestion. The results showed that carbamazepine induced the enrichment of ARGs and increased the abundance of bacteria carrying these genes. It also facilitated microbial aggregation and intercellular communication, leading to an increased frequency of ARGs transmission. Moreover, carbamazepine promoted the acquisition of ARGs by pathogens and elevated their overall abundance.

Summary: This paper developed a machine learning model to predict the biochemical methane potential during anaerobic digestion. Model analysis identified lignin content, organic loading, and nitrogen content as key attributes for methane production prediction. For feedstocks with high cellulose content, early methane production is lower but can be improved by prolonging digestion time. Moreover, lignin content exceeding a certain value significantly inhibits methane production.
