Summary: This study aimed to energetically valorize sludge from wastewater treatment plants and discharges from the wine sector through anaerobic co-digestion. Two different processes, single-stage mesophilic anaerobic digestion and Temperature-Phased Anaerobic Digestion (TPAD), were employed for the valorization. Biodegradability tests were conducted to determine the methane production yield, and the results showed that the single-stage process was more effective in methane generation compared to the TPAD process.

Summary: The anaerobic co-digestion of food waste and algae was assessed to overcome the drawbacks of anaerobic mono-digestion. Batch tests showed that a food waste and algae mixture ratio of 8:2 resulted in the highest CH4 yield. Implementing this ratio in the anaerobic co-digestion reactor led to double the CH4 yield compared to anaerobic mono-digestion reactors, ensuring high operational stability. Furthermore, metagenomic analysis revealed an increase in the abundance of important methane-producing bacteria in the anaerobic co-digestion reactor.

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.
