Summary: In the study, a combined technology for co-digestion of brewery spent grain and sewage sludge was presented, involving hydrodynamic cavitation pretreatment and different carriers. It was found that significant increases in biogas/methane production were achieved under certain conditions. However, it is recommended to implement full-scale co-digestion only with cavitated brewery spent grain and municipal pre-settled wastewater.

Summary: Brewery Spent Grain (BSG) is a fibrous residue rich in protein and amino acids, widely used for animal feed and biogas production. It serves as a nutrient source for plants and microorganisms and can also be used to produce biochar and biocatalysts. BSG's potential applications in biorefinery for obtaining enzymes, biopolymers, and biofuels have been highlighted, but further studies on operational conditions, cost, energy efficiency, and product performance are still needed for its consolidation as a feedstock.

Summary: The present study evaluated the anaerobic co-fermentation of brewery by-products for hydrogen production. The results showed that the removal efficiency of total volatile solids (TVS) reached a maximum of 30.86%. Acetic and butyric acids were the dominant volatile fatty acids produced. The addition of brewer's spent grains (BSG) promoted an increase in nitrogen concentration and decreased the hydrogen yield.

Summary: A new anaerobic digestion process based on arrested methanogenesis (AM) was developed to treat high-strength cheese whey and brewery wastewater with simultaneous carboxylic acid production. Experimental results demonstrated that under suitable conditions, high total carboxylic acids concentration could be achieved, with lactate conversion to chain-elongated volatile fatty acid observed. Fed-batch digestion with biomass recycling resulted in a 2-fold increase in VFAs concentration and higher diversity in the microbial consortia.

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: This study investigated the effect of bioaugmentation on the performance of sequencing batch reactors (SBRs) in treating municipal wastewater and reject water under different temperature conditions. The results showed that bioaugmentation led to lower concentrations of NH4+-N, TSS, and NO2--N in the effluent compared to the control group, with statistically significant differences observed for NH4+-N regardless of temperature variations. The process was conducted stably in both SBRs.

Summary: This study evaluated the effectiveness of hydrodynamic cavitation (HC) as a pre-treatment method for organic wastes. The results showed that HC could solubilize and decompose complex organic matter, and improve the biodegradability index and soluble chemical oxygen demand content. However, suitable operational conditions need to be chosen individually for each waste type.

Summary: This study investigated the effect of hydrodynamic cavitation (HC) on the biodegradability of herbal waste suspended in municipal wastewater after mechanical pre-treatment. The results showed that HC at an inlet pressure of 3.5 bar and a cavitation number of 0.11, with 30.5 recirculation passes through the cavitation zone, significantly enhanced the BOD5/COD ratio within 10 minutes, indicating improved biodegradability. Fiber component analysis, FT-IR/ATR, TGA, and SEM analysis confirmed that HC visibly influenced the chemical and morphological structure of herbal waste, reducing hemicellulose, cellulose, and lignin content without forming by-products that would affect subsequent biological treatment of the waste.

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.
