Summary: The study investigated the potential of improving methane production from algal sludge anaerobic digestion by peroxydisulfate (PDS) pretreatment. Results showed that PDS dosage at 0.02 g PDS/g algal sludge TSS led to the highest accumulative methane production after 60 days fermentation. The addition of PDS inhibited microbial activities but improved short chain fatty acids production.

Summary: Efficient nutrient cycling is crucial for sustainable agriculture, and using waste products from different industries can contribute to this process. This study explored the potential of using anaerobic digestate from food industry waste as a nutrient source for fertilizer production. Different sanitization methods were used, with acidic hydrolysate yielding a higher concentration of amino acids compared to alkaline. Granular fertilizers were formulated using various ingredients, and nitrogen balances were analyzed. The effectiveness of the fertilizers was evaluated through wheat germination tests, and the results indicated the potential of using anaerobic digestate for nutrient recycling in agroecosystems.

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: This study investigated methane production from soybean molasses anaerobic digestion and evaluated the impact of different factors on system stability and performance. The best results were achieved with a fed-batch mode, fill time of 180 min at 30 degrees C, and an organic loading rate of 14.9 kg-COD/m3/d. The study also estimated the scale-up requirements and investment needed for industrial implementation.

Summary: The diversion of organic waste through anaerobic digestion presents an opportunity to recover valuable nutrients like nitrogen and phosphorus, with municipal sewage sludge being the largest potential source for recovery. The nutrient recovery rates vary for different end products, with liquid fertilizer, struvite, and compost contributing to offsetting synthetic fertilizer demand in California to different extents. In a profitable build-out scenario for anaerobic digestion facilities, recovered nutrients could offset a significant portion of the state's synthetic fertilizer demand.

Summary: This study explores the potential of using hydrothermal carbonisation (HTC) to fractionate anaerobic digestate of sewage sludge into hydrochar and aqueous phase (AP), which is then used to cultivate alkali halophilic microalgae. The results show that the AP obtained from HTC can serve as a suitable growth medium substitute, promoting microalgae growth and increasing biomass yield.

Summary: The study found that planting catch crops can reduce nitrogen leaching caused by maize fertilization, with catch crops showing high nutrient uptake. Ensiling is an effective storage method that can increase methane production, and catch crops can also serve as a good co-substrate to achieve nutrient recycling closure.

Summary: This study evaluated the effect of ultrasonic disintegration on the performance and energy efficiency of anaerobic digestion of Scenedesmus sp. and Pinnularia sp. microalgal biomass. The pretreatment significantly increased dissolved COD and TOC in the system. The highest CH4 yields were achieved for Scenedesmus sp. sonicated for 150 s and 200 s, while Pinnularia sp. exhibited poorer performance compared to non-pretreated biomass.

Summary: This study assessed the potential use of strawberry extrudate (SE) as a carbon source for volatile fatty acid (VFA) production under different pH conditions. Anaerobic digestion at pH 7 resulted in methane production, while at pH 9 and 5, VFA accumulated with acetic acid being the predominant VFA at pH 9 and propionic and butyric acids being the major VFAs at pH 5.

Summary: The study found that silica and aluminum oxide slurries at environmentally relevant concentrations are unlikely to cause acute toxicity to marine bacteria. Silica and fumed silica slurries at high concentrations resulted in cell death, indicating that the toxicity of these model CMP slurries is mainly due to the abrasive NPs.

Summary: FeS minerals can rapidly reduce DNAN and NTO to their corresponding amines under anoxic conditions. Mackinawite predominantly reduces DNAN to MENA and partially to DAAN, while completely reducing NTO to ATO. This study provides the first evidence of FeS minerals reducing a nitro-heterocyclic compound like NTO.

Summary: Nitroguanidine (NQ) is a compound widely used in various applications, such as automobile airbags, pyrotechnics, and insecticides. In this study, the anaerobic biotransformation of NQ was investigated, and a sulfate-reducing culture using lactate as an electron donor was found to effectively reduce NQ to nitrosoguanidine. The microbial community associated with NQ biotransformation was dominated by sulfate-reducing and fermentative bacteria.
