Summary: Coal gasification is an effective method for clean and efficient utilization of coal, and the by-product of coal gasification, coal gasification fine slag, has high carbon content, large specific surface area, developed pore structure, and high output. Combustion has become an effective large-scale disposal method for coal gasification fine slag, and the fine slag after combustion can be further used as construction raw materials. This study investigated the emission characteristics of gas-phase pollutants and particulate matter under different combustion conditions, and found that co-firing coal gasification fine slag with raw coal can reduce submicron particle emission and total emission of gas-phase pollutants. Elemental analysis showed that furnace temperature and O2 concentration significantly influenced the formation of submicron particles.

Summary: The effects and mechanisms of CGFS-CWS preparation, combustion, and ash fusion were investigated. Increasing CGFS content led to higher slurry viscosity but improved slurry stability. The improved stability was attributed to the stronger negative charge on the CGFS surface, facilitating particle dispersion. Combustion experiments showed that CGFS incorporation significantly lowered the burnout temperature and increased the maximum combustion rate of the slurry. Addition of CGFS also reduced the ash fusion temperature by promoting melting-assisting effects.

Summary: This study aimed to develop a bioprocess for the production of 2,5-Furandicarboxylic acid (FDCA), a platform chemical and monomer used in plastic industries. A bioprocess was successfully developed using pineapple peel-derived 5-(Hydroxymethyl)furfural (HMF) as a precursor for FDCA production. The bioprocess involved the use of Aspergillus flavus APLS-1 to convert HMF into FDCA, with a yield that can be further improved in the future. This study is the first to report the production of FDCA from pineapple 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.
