Summary: Recently, there has been growing interest in using organic or biodegradable wastes, including lignocellulosic wastes (LWs), as renewable energy sources. Anaerobic digestion (AD) of these wastes can mitigate environmental damage and produce biogas and bioenergy, which is particularly valuable in developing countries. However, there are several challenges to overcome, such as waste floating on top of reactors, high carbon-to-nitrogen ratio (CNR), complex structure of LWs, and poor degradability due to high lignin content. These challenges can be addressed through methods like mixing in reactors, reducing CNR, balancing inoculum-to-substrate ratio (ISR), and pretreatments. This study aims to review the literature on AD of LWs, identify existing challenges, and propose strategies to improve bioenergy production from this waste.

Summary: This study evaluated the pretreatment of sugarcane bagasse with dilute citric acid solution for biogas production. The pretreated black liquor and residual solid fraction were used as substrates for biogas production. The highest concentration of total reducing sugars obtained after saccharifications was in the range of 10.7-184.8 g L-1, with sugar yields ranging from 3.5-88.8%. Biogas production from the black liquor and residual solid fraction showed promising results, indicating the feasibility of using dilute citric acid pretreatment in biorefineries.

Summary: Sewage sludge management is a topic of interest due to the challenges of overpopulation and its potential as a bioenergy source. Thermal hydrolysis is a promising technology for sludge pre-treatment, but faces challenges such as dark color affecting UV disinfection and the formation of inhibitors impacting methane production. Advanced thermal hydrolysis, an oxidative process, has been introduced to overcome these challenges.

Summary: Anaerobic digestion (AD) is a sustainable method for recovering energy from organic wastes, but the efficiency for waste activated sludge (WAS) is limited due to WAS hydrolysis constraints. This study proposes a strategy to treat WAS and landfill leachate simultaneously, aiming to enhance WAS hydrolysis and organic conversion to methane. The effects of landfill leachate on the different stages of AD of WAS were investigated, showing that appropriate amounts of leachate can promote solubilization, hydrolysis, and acidogenesis, but not methanogenesis. Mechanism studies revealed the beneficial effects of humic acid in leachate on hydrolysis and acidogenesis, and the dose-dependent effects of heavy metals on the AD process. Additionally, microbial community analysis showed an increase in microbes responsible for hydrolysis and acidogenesis with the presence of landfill leachate.

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.
