Jun 15, 2024 · The following inclusion criteria had to be met: i) the study was an original experiment; ii) composting was performed at laboratory scale, and simulating composting was not included; iii) the composting process was complete, as indicated by the compost temperature remaining stable at ambient temperature; iv) the feedstock type was pig manure
Jun 22, 2024 · The Inner Mongolia Autonomous Region is a crucial area in China with a significant advantage in animal husbandry, particularly in cattle and sheep farming. However, the disposal of the large quantities of manure produced during farming has severely impacted the industry’s healthy development. Proper treatment of the manure can convert it into organic fertilizer beneficial to farmland
Oct 1, 2023 · Hence, using anaerobic digestate as a biofertilizer is a common practice in sustainable agriculture. The digestate quality was equivalent to other biofertilizers such as compost manure from aerobic composting and vermicomposting (Isha et al., 2020; Vijay et al., 2021a; D’ Silva et al., 2022b). But the quality of anaerobic digestate is
Jul 21, 2023 · As livestock and poultry farming expands in China, the generation of fecal waste has significantly increased. Inadequate waste management can contribute to environmental pollution. This study seeks to optimize small-scale composting systems to address the inefficiencies and the limited automation of traditional composting equipment. We redesigned the mixing blades and refined the ventilation
Sep 1, 2022 · Aerobic composting provides an environmentally friendly treatment method, but improving humification of raw materials remains a challenge. This study revealed the effect of different concentrations of potassium persulfate (PP) on humification of chicken manure and straw aerobic composting and the underlying microbial mechanisms.
Jul 30, 2024 · Composting is the aerobic decomposition of manure or other organic material by microorganisms in a managed system. Composting requires air, moisture, and high-nitrogen and high-carbon organic material. Typically, manure and bedding or wood chips are the high-nitrogen and high-carbon materials, respectively.
Oct 15, 2021 · Occurrence of antibiotic resistance genes (ARGs) in animal manure impedes the reutilization of manure resources. Aerobic composting is potentially effective method for resource disposal of animal manure, but the fate of ARGs during composting is complicated due to the various material sources and different operating conditions.
Aug 1, 2023 · However, most livestock manure has high moisture content, poor permeability, and low microbial activity. Aerobic composting using only livestock manure involves slow compost heating, long fermentation cycles, and low decomposition rates (Qian et al., 2016).
Apr 1, 2019 · Abstract With the aim to comparatively investigate the effect of the addition of additives such as biochar (BC), microbial inoculation (MI) and biochar/microbial inoculation (BCMI) on composting enhancement, nitrogen conservation, greenhouse gas emissions, the quality improvement of pig manure compost were comparatively investigated in a 42-day aerobic pig manure composting experiment. The
Jul 15, 2023 · The membrane-covered aerobic composting is an improved mode of forced ventilation composting. This method uses a membrane with selective permeability, which is waterproof and moisture-permeable, preserving nitrogen and improving efficiency while effectively reducing odor (Fang et al., 2022).
3 days ago · Aerobic composting has been used as a mainstream treatment technology for agricultural solid waste resourcing. In the present study, we investigated the effects and potential mechanisms of the addition of a microbial agent (LD) prepared by combining Bacillus subtilis, Bacillus paralicheniformis and Irpex lacteus in improving the efficiency of cattle manure composting.
Composted plant and animal manures (§205.203(c)(2)) are those that are produced by a process that: (i) established an initial C:N ratio of between 25:1 and 40:1; and (ii) maintained a temperature of 131°F to 170°F for 3 days using an In tank or static aerated pile system; or (iii) a temperature of between 131°F and 170°F for 15 days
Mar 15, 2020 · Here, we analyzed the fate of microbial communities and ARGs of cow manure treated by three conventional management strategies: aerobic composting, mechanical drying and precipitation, applying an integrated-omics approach combining metagenomics and metaproteomics.
Nov 17, 2021 · In the aerobic composting fermentation process, the change of the thermal phase is the most important parameter determining whether the cow manure can be decomposed [40, 41]. Maintaining a sufficiently long high-temperature section can increase the decomposition efficiency of the compost, while also killing eggs, pathogens, parasites, and spores.
Dec 18, 2023 · What is Composting? Composting is a controlled, aerobic (oxygen-required) process that converts organic materials into a nutrient-rich, biologically-stable soil amendment or mulch through natural decomposition. The end product is compost. Microorganisms feed on the materials added to the compost pile during the composting process.
