Summary: This review investigates the distribution of antibiotics in livestock manure, the degradation of antibiotics during bioenergy production, and the removal mechanisms of antibiotics by different treatment technologies. By exploring the fate and conversion of antibiotics, it provides new research directions in the field of bioenergy conversion of livestock manure.

Summary: Veterinary antibiotics contamination is a global environmental and health concern, mainly originating from animal feces and present in manure, soil, water, and sediment. Different types of antibiotics have varying distribution, and removal technologies include anaerobic digestion, manure composting, and constructed wetlands.

Summary: The study found that thermophilic anaerobic digestion at 52 degrees Celsius significantly reduced the abundance of antibiotic resistance genes, with reductions faster during the startup phase and exceeding 50% in the first five days for most genes. High temperature anaerobic digestion may be more effective than low temperature digestion in reducing antibiotic resistance genes.

Summary: Transforming hazardous livestock manure into biochar as a catalyst for advanced oxidation processes is an effective method for treating waste. This study developed a self-modified biochar catalyst derived from chicken manure for the degradation of levofloxacin hydrochloride. The catalyst exhibited high degradation efficiency, and the reaction mechanism involved several non-radical routes. This work provides insights into the utilization of chicken manure and the activation of peroxymonosulfate for organic contaminant removal.

Summary: This study reveals the presence of antibiotic-resistant bacteria (ARB) in the effluent of a wastewater treatment plant (WWTP) and the growth of ARB/ARGs in microplastic biofilms. The abundance of viable ARB in the microplastic biofilms increased between days 3 and 5 and then decreased on days 7 and 9. ARGs were detected in the microplastic biofilms in both tap water and WWTP effluent.

Summary: This study aimed to investigate the chronic effects and recovery from inhibition in the anaerobic digestion of swine manure containing chlortetracycline. Two reactors were operated for 900 days, with one reactor spiked with CTC. Methane generation and organic removal did not recover within 300 days after CTC exposure was stopped, due to reduced bacterial diversity and shift in microbial species under long-term antibiotic pressure. Continuous exposure to CTC should be avoided for sustainable management of AD plants treating swine manure.

Summary: The study found that in open pig farming systems, there is a high level of E. coli populations, antibiotic contamination in supplied water, and additional antibiotic usage, such as neomycin or colistin. Additionally, an increased occurrence of ARE was found in anaerobic digestion and waste stabilisation ponds, but they were not well correlated with their residual antibiotic concentrations.

Summary: This study predicts the concentrations of chlortetracycline in slurry pit and soil, evaluating ecological risks, based on livestock farming practices and uncertainties. The Monte Carlo simulation was used for sensitivity analysis, revealing key factors influencing CTC exposure in soil. The results suggest that ecological risks of CTC in soil can be controlled through appropriate slurry pit farm practices.

Summary: Substituting organic fertilizer for chemical fertilizer can improve soil quality but also increase antibiotic residues in agricultural soil, leading to a tradeoff between benefits and risks. Proper management practices of organic fertilizers are needed to balance the effects of soil quality improvement and antibiotic contamination.

Summary: The study investigated distribution of MPs in 19 livestock and poultry farms, identifying PP and PE types of MPs dominated by colorful fragments and fibers. The study proposed potential transport pathways for MPs in manure and feeds, revealing that direct application of swine and poultry manure could be a new route of MPs in agricultural soil. This research not only highlights the contamination risk of MPs in livestock and poultry manure, but also provides insights for remediation of MP-contaminated soil.

Summary: Antibiotic resistance genes (ARGs) are widely found in organic solid waste, and the conventional composting technology has limited effect on their removal. Improved composting processes, such as hyperthermophilic temperature composting, can effectively eliminate ARGs, with the transfer of ARGs influenced by microbial communities identified as a vital factor.
