Summary: Catalytic pyrolysis of cow manure using HZSM-5, HBeta, and HY zeolites was conducted, and HZSM-5 showed the highest production efficiency of benzene, toluene, ethylbenzene, xylene, and naphthalene. The acidity and pore structure of the catalysts played a crucial role in the efficiency. Increasing the acidity, reaction temperature, and catalyst-to-feedstock ratio further increased the production of BTEXN and decreased oxygen-containing compounds.

Summary: With the increase of global demand for cash crops, a large amount of waste is produced, which causes severe environmental issues. This study investigated the effects of different substrates on the fermentation characteristics of Agricultural Jiaosu (AJ), including metabolites and microbial community properties. The results showed that AJ fermentation is a process of converting organic matter into organic acids and other metabolites, and the composition of key microorganisms depends on the substrate type. It was concluded that AJ is an innovative eco-friendly technology that can convert cash crop waste into sustainable ecoproducts, and the substrate used should be carefully selected according to the application field.

Summary: Solid anaerobic digestion of chicken manure leads to VFAs accumulation. Addition of TEs helps stabilize the system but excessive supplementation causes pollution. This study explores the use of biochar to reduce TE addition. Results show that biochar reduces TE supplementation by 50% and increases the bioavailability of TEs. Biochar also enriches conductive microorganisms and beneficial bacteria. Overall, biochar is an ideal material for reducing TE amounts in anaerobic digestion systems.

Summary: Aquaculture costs in China have risen due to the increase in fish meal prices. Fermented soybean meal (FSBM) has the potential to replace fish meal partially and reduce the cost of aquatic feed. FSBM increased crude protein content and reduced phytic acid concentration. When less than 30% of fish meal was replaced by FSBM, there was no significant difference in weight gain and feed conversion ratio. However, higher FSBM substitution levels adversely affected liver steatosis, intestinal villi dimensions, and gene expression levels.

Summary: This study compared the effects of hydrochar and granular activated carbon (GAC) on the anaerobic digestion (AD) of phenol. Results showed that hydrochar significantly improved methane production rate and reduced the lag phase for all phenol concentrations. GAC only increased methane production rate at high phenol concentrations due to its high adsorption capacity. 16S rRNA transcripts sequencing and metabolomic analysis revealed the enrichment of syntrophic bacteria and Methanosaeta with hydrochar, which may be related to direct interspecies electron transfer. Metabolomic analysis also showed that hydrochar promoted the degradation of phenol into methane.

Summary: With the rapid expansion of biogas plants, there is an increasing amount of biogas residues. Composting is widely used to handle these residues, with aeration regulation being the key factor in achieving high-quality fertilizer or soil amendment. This study investigated the impact of different aeration regulations on the maturity of full-scale biogas residues compost by controlling oxygen concentration under micro-aeration and aeration conditions. The findings showed that micro-aerobic conditions extended the thermophilic stage and promoted the mineralization process, resulting in higher nitrogen nutrition levels. Various parameters such as TOC, NH4+-N, NO3--N, TK, TP, and GI can be used to evaluate the stabilization, fertilizer efficiency, and phytotoxicity of the compost.

Summary: With the development of the biogas industry in China, there is a large amount of by-product called biogas slurry. The static storage of biogas slurry, which is commonly used before applying it to land, can lead to nutrient decomposition and greenhouse gas emission. This study aimed to investigate the decomposition of nutrients, emission of greenhouse gases (CH4 and N2O), and phytotoxicity of biogas slurry under different temperatures. The results showed that higher temperature at 30 degrees C promoted the degradation of COD and had less toxicity to crops. CH4 was the dominant greenhouse gas emitted, and its emission was highest at 30 degrees C. Lower temperature reduced greenhouse gas emission but adversely affected the stabilization of organic matter and crop safety. These findings can be used to monitor environmental risk, evaluate maturity, guide irrigation schemes, and regulate the storage conditions of biogas slurry.

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.
