Summary: This study investigated the anaerobic digestion of compost leachate in completely stirred tank reactors (CSTR) and analyzed the kinetics of the process. The results showed that the Monod model and Haldane model accurately described the degradation rates of chemical oxygen demand (COD) under different operating conditions. These findings are important for the management and design of digesters for compost leachate treatment.

Summary: This study focuses on developing a kinetic model for the production of n-butyl levulinate (BL) from sugar butanolysis over heterogeneous catalysts. The complex kinetics of sugar monomer butanolysis over heterogeneous catalysts, due to various side reactions, such as esterification and humin production, were investigated. A reliable model was developed by primarily focusing on the butanolysis of 5-(hydroxymethyl)furfural (5-HMF) over Amberlite IR-120.

Summary: The volume of ethanol production waste-molasses waste in Ukraine reaches up to 4 million m(3) per year and is causing environmental pollution. The development of an effective technology for using molasses in biogas plants to obtain energy gas-biogas is urgently needed. The goal of this study was to determine the optimal volume of molasses bard loaded into the methane tank in a quasi-continuous mode to maximize biogas production. Experimental studies were conducted on a laboratory biogas plant to determine the maximum biogas output based on different molasses compositions. The results showed that adding 10.5% and 26.1% molasses to cattle manure resulted in the highest biogas output under the periodic loading system. Adding molasses in the amount of 30% of the substrate volume based on cattle manure is recommended to increase biogas production.

Summary: The study investigated the effects of different liquid-liquid flow patterns on the extraction of 5-hydroxymethyl furfural, finding that extraction efficiency varied irregularly with increasing flow rates, and mass transfer rate significantly increased at high flow rates with a trade-off of high-pressure drop. The ethyl acetate/water irregular flow pattern performed the best with high extraction efficiency and mass transfer coefficient, and minimal pressure drop.

Summary: Furan derivatives and aromatic acids derived from lignocellulosic biomass are important intermediates with potential for producing bio-based chemicals and fuels. These compounds have useful antioxidative, antibacterial, and anti-aging activities. Protocatechuic acid, derived from lignin biomass, is an essential aromatic intermediate with active acid and hydroxyl groups, and can be used for the production of value-added chemicals such as HMF and furfuryl alcohol. Platform compounds based on furans are widely used due to their chemical structure, allowing the preparation of various high-value-added chemicals.

Summary: UiO-66-derived H2N-UiO-66-SO3H with acid-base active sites was used for the co-production of 5-hydroxymethyl furfural (5-HMF) and furfural (FUR) in the direct conversion of holocellulose composed of cellulose and hemi-cellulose. The prepared catalyst demonstrated excellent performance, achieving high yields of 39.1% and 28.2% for 5-HMF and FUR, respectively. Furthermore, the catalyst displayed good stability and could be reused for multiple cycles with only a slight decrease in product yields.

Summary: Pretreatment of dairy manure can effectively increase methane production by disrupting lignocellulosic structure and increasing soluble sugars, with SPORL treatment showing the highest methane yield. The pretreatments also lead to a reduction in cellulose/hemicellulose fractions and an increase in soluble sugars, improving anaerobic digestibility and nutrient recovery.

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.
