Summary: This study investigated the transformation of mercury species, especially methylmercury, in sludge composting. The findings showed that there was no significant change in the overall content of mercury and methylmercury before and after composting, but a certain percentage of both were lost. Anaerobic bacteria were identified as the main methylators of mercury in the initial stages of composting. The study also revealed the presence of genes related to mercury transformation in various microbial genomes.

Summary: This study developed a Fenton-like system using calcium peroxide (CaO2) in a composting system to examine the influence of antibiotic resistance genes (ARGs) and bacterial community structure. The results showed that CaO2 facilitated the reduction of ARGs, with a 19.02% lower abundance in the test group compared to the control group. The addition of CaO2 also led to significant changes in the bacterial community structure.

Summary: This study investigated the effects of thermal hydrolysis pretreatment (THP) on sludge humification and the related regulatory mechanisms during anaerobic digestion (AD). The results showed that THP at different temperatures affected the humification process of sludge during AD. The availability of polysaccharides, determined by their occurrence state and molecular structure, played a crucial role in sludge humification and could be regulated by THP.

Summary: Anaerobic cores in compost particles emit harmful off-gases, and air immobile region is a significant factor in creating an anaerobic environment. This study used a two-region model (TRM) to investigate the effect of different bulking agents on the air-immobile region during composting. A fitted equation coupled model was developed to simulate the relationship between surface oxygen concentration and aerobic/anaerobic layer thickness. The results showed that adding peanut shells and wheat straw reduced the air-immobile regions and enhanced gas transfer in the compost pile.

Summary: Syngas, a mixture of hydrogen and carbon monoxide, is an important feedstock for the production of chemicals and fuels. The tunable H2/CO ratio of syngas produced through sorption-enhanced steam gasification of sewage sludge offers a promising approach to integrate biomass gasification with syngas application, allowing for the production of value-added products. The potential of two-stage SESG in promoting tar decomposition for enhanced syngas production is also highlighted.

Summary: This study investigated the impact of biochar on the degradation of organophosphate esters (OPEs) during the aerobic composting of sewage sludge. The results showed that 10% biochar greatly promoted the decomposition of organic matter and significantly increased the degradation rate of OPEs. The presence of 10% biochar eliminated approximately 43.6% of the OPEs concentration.

Summary: The aim of this study was to explore the dynamics and transformation pathways of dissolved organic matter (DOM) in sewage sludge (SS) during composting. The DOM of raw material, material experiencing thermophilic phase, and material collected from humification phase were characterized. The results showed that aliphatic/proteins and carbohydrate were preferentially decomposed in the thermophilic phase, while lignins/CRAM were the main N-containing substances evolved. The newly formed compounds in the maturity phase were beneficial for humic substances formation.

Summary: This study investigated the effects of biochar derived from different sources on greenhouse gas and microplastics mitigation during sewage sludge composting. The addition of biochar significantly reduced N2O emissions and NH3 emissions, while having no apparent effect on CH4 emissions. Biochar also decreased the global warming potential and promoted the oxidation and degradation of microplastics. Moreover, biochar reduced the abundance of small-sized microplastics and regulated specific microbes to mitigate greenhouse gas emissions and microplastics degradation.

Summary: Microplastics, as emerging contaminants, are widely present in various mediums, including sewage sludge. During the sewage treatment process, a large number of microplastics are deposited in the sludge and can migrate to other environmental media, posing a threat to human health. Therefore, the removal of microplastics from sewage sludge is necessary. Among various restoration methods, aerobic composting is emerging as a green method for microplastic removal. However, there are few studies on the degradation mechanism of microplastics in aerobic composting, hindering the innovation of composting methods. This paper discusses the degradation mechanism of microplastics in sewage sludge based on environmental factors and explores their potential hazards and future studies.

Summary: During a 12-month study in Sweden, it was found that open-air storage without composting showed effective removal of hormones and antibiotics, but lower removal of pharmaceutically active substances. Composting resulted in degradation of hormones and a noticeable difference in concentrations of pharmaceuticals between the top and deeper layers of sludge piles.

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.
