Sep 1, 2023 · Abstract. Composting experiment of swine manure, adding with yellow phosphorus slag (YPS) at 5% (w/w), was conducted in an industrial-scale reactor covered with semi-permeable membrane. During 27 days of composting, the changes in temperature, compost quality and phosphorus (P) speciation of products were monitored.
May 5, 2023 · Composting pig manure can help to break down organic matter and pathogens, as well as improve soil structure and water-holding capacity. Moreover, composting pig manure can also reduce the volume and weight of manure, making it easier to handle and transport. By using pig manure as fertilizer responsibly and considering composting as an option
This study investigated the effect of biochar on antibiotics and antibiotic resistance genes (ARGs) during aerobic composting of pig manure. First, the composition and content of antibiotics in the manure were determined qualitatively and quantitatively. Biochar promoted the degradation of these ant
Feb 1, 2024 · Greenhouse gas (GHG) emissions from manure management processes deserve more attention. Using three industrial-scale experiments, this study comprehensively evaluated the effects of different aeration coupled with semi-permeable membrane-covered strategies on the structure and function of bacterial communities and their impact on GHG emissions during dairy manure aerobic composting.
Feb 1, 2024 · DOI: 10.1016/j.cej.2024.149581 Corpus ID: 267717707; Electrokinetic technology enhanced the control of antibiotic resistance and the quality of swine manure composting @article{Li2024ElectrokineticTE, title={Electrokinetic technology enhanced the control of antibiotic resistance and the quality of swine manure composting}, author={Binxu Li and Muhammad Fahad Sardar and Xu Zhang and Jing Ye and
Jul 22, 2022 · Pig manure is a reservoir of antibiotics and antibiotic resistance genes (ARGs). The effect of biochar on the variations in physicochemical properties, bacterial communities, antibiotics, ARGs, and mobile genetic elements (MGEs) of compost product during co-composting of pig manure and corn straw have been investigated in this study.
May 1, 2024 · The tested strain X1 was isolated from the fresh pig manure sample after the aerobic compost fermentation process. The solid Luria-Bertani (LB) medium containing 10 mg/L of Cd 2+ and 100 mg/L of Zn 2+ was used to isolate bacteria with heavy metal tolerance. Five grams of the fresh compost sample were oscillated in a triangular flask containing
The influence of compound microbial agents on antibiotic resistance genes (ARGs) in pig manure composting was investigated. The results show that the addition of microbial agents promoted the reduction of total ARGs and the maximum removal efficiencies for absolute abundance (77.2%) and relative abundance (64.5%) were observed in the repeated
In order to study the feasibility of using GM cotton stalks for composting and the changes that occur in antibiotic resistance genes (ARGs) during composting, we supplemented pig manure with GM or non-GM cotton stalks during composting and we compared their effects on the absolute abundances (AA) of intI1, intI2, and ARGs under the two treatments.
Nov 1, 2023 · Animal manure is a primary repository of antibiotic resistance genes (ARGs) and mobile genetic elements (MGEs). This work explored the efficiency of ARGs and MGEs removal during pig manure composting after thermal pretreatment (TPC) and the underlying mechanisms. TPC resulted in a decrease of 94.7% and 92.3% in the relative abundance of ARGs
Jun 18, 2020 · Composting pig manure and sawdust with urease inhibitor: succession of nitrogen functional genes and bacterial community. Research Article. Published: 18 June 2020.

Aug 1, 2020 · The 16S rDNA abundance of composts in this study was the same order of magnitude as swine manure compost from a large farm (~10 12 copies/g (dw)) (Cao et al., 2020) and 1-3 orders of magnitude
May 15, 2017 · Successful co-composting of chestnut forest green waste and MDF sludge was achieved. •. Pig manure decreased the C/N ratio and increased moisture content of the mixture. •. Active composting process was sustained for about two months. •. The addition of MDF sludge strongly reduced nitrogen losses during composting. •.
Jan 15, 2021 · Nowadays, composting is a better option to solve these problems. Accordingly, this study explored the effects of co-composting swine manure with different inoculants dominated by Phanerochaete chrysosporium (p), Aspergillus niger (a), and Bacillus licheniformis (b) on the simultaneous removal of multiple antibiotics and resistance genes and
Jul 25, 2023 · Our results suggest that while none of the processes eliminates the environmental risk, composting results in a faster and more pronounced reduction of mobile genetic elements harboring
The International Livestock Expo – ILDEX PHILIPPINES 2025 is set to take place from August 27–29 at the SMX Convention Center in Manila, Philippines! Henan Bolong will showcase its core equipment and livestock manure solutions at Booth No. C11.
Traditional manure composting is prone to complaints and environmental fines due to the decomposition of organic matter, uncontrolled fermentation environment and unsealed diffusion.Bolong sealed composting tank blocks odor at the source of the sealed tank and removes odor at the end of the spray tower (with an efficiency of over 95%), combined with high-temperature aerobic fermentation to inhibit odor-producing bacteria, effectively solving the odor problem. Mature manure can be directly used as fertilizer or sold to increase income, suitable for large-scale farms, and can be quickly matured to meet standards in 7 days. The equipment helps farms comply with environmental regulations and avoid penalties, and intelligent control reduces costs and increases efficiency, achieving odor elimination and turning waste into treasure.
