Summary: In this study, the effects of cerium dioxide nanoparticles (CDNs) on the anaerobic digestion (AD) of wheat straw were evaluated. The results showed that CDNs effectively enhanced the reducing power and utilization of volatile fatty acids (VFAs), leading to increased methane production. Analysis of the microbial community structure indicated that CDNs increased bacterial abundance in hydrolytic acidification. These findings are of great importance for improving the methane production efficiency of AD and studying the role of nanoparticles in promoting AD.

Summary: The effects of ensiling and brown juice-assisted ensiling on methane yield and nutrient availability in digestates were investigated in this study. The results showed that ensiling of straw increased inorganic nitrogen release in soil and reduced inorganic sulphur immobilisation, while brown juice-assisted ensiling significantly increased methane production and improved hydrolysis and methane production rates. These findings suggest that ensiling can enhance biogas production and nutrient availability, and provide a method to valorise brown juice as an ensiling additive.

Summary: Agro-waste, particularly wheat straw, is an effective material for energy recovery through anaerobic digestion. However, the complex lignocellulosic structure hinders their conversion and is a limiting factor in the AD process. Physical and chemical pretreatments can overcome these barriers, with ionic liquids emerging as a renewable and efficient option. Bacterial pretreatment is superior to fungal and algal pretreatments for biological pretreatment.

Summary: This study investigated the impact of co-digestion of waste activated sludge and primary sludge with various organic wastes on biogas production. The results showed that adding cheese whey and grease interceptor waste increased methane production by 15% and 2% respectively, and improved volatile solids removal. However, co-digestion of cheese whey and primary sludge did not enhance biogas production, whereas mixing grease interceptor waste and pulped food waste with primary sludge showed potential for improved biogas production. Additionally, detailed energy balance analysis of a water resource recovery facility was conducted to understand the influence of co-digestion on energy neutrality.

Summary: The study evaluated three different start-up strategies for hydrogen production from thermophilic dark fermentation, with strategy (iii) increasing hydrogen productivity by 39% compared to the others. The combination of high temperature and low pH favored hydrogen-producing routes, potentially boosted by synergy between different bacteria. A total of three 41 m(3) reactors would be needed to treat 3.4 x 10(3) m(3) year(-1) of whey in small-size dairy industry, with the energy produced reaching 14 MWh month(-1).

Summary: This study investigated the effect of soft hydrothermal pre-treatment on olive mill solid waste (OMSW) and its subsequent anaerobic digestion. The pre-treatment at 121 degrees C and 1.1 bar for 30 minutes showed the highest methane yield. The solubilization of important compounds and reduction of fiber size were observed after pre-treatments, leading to an improved digestibility of OMSW. The influence of pre-treatment conditions on the anaerobic digestion process was evaluated through process performance monitoring and kinetic parameters calculation.

Summary: This research evaluated the anaerobic digestion of llama and dromedary dungs in batch mode at mesophilic temperature. The study found that trampled llama dung had a higher methane yield compared to raw llama and dromedary dungs. Trampled llama dung was determined to be the best substrate for methane production due to its high volatile solids content, nitrogen content, and appropriate C/N ratio. The experimental data aligns with both first-order kinetic and transference function mathematical models.

Summary: In order to reduce environmental impact and improve resource sustainability, the use of landrace cultivars that support regenerative agriculture needs to be promoted and strengthened. This study evaluated the growth, development, and anaerobic digestion of different sorghum varieties, including landrace cultivars and commercial hybrids. The landrace cultivars showed better performance in terms of height, biomass yields, compactness shoots, and grain production compared to commercial varieties. The anaerobic digestion of the sorghum straws was carried out at mesophilic temperature, and the landrace cultivar Zahina obtained the highest methane yield. Mathematical models were used to describe and simulate the anaerobic biodegradation, and the commercial variety PR88Y20 exhibited the fastest biomethanization.

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.
