Feb 14, 2024 · Livestock manure management plays a crucial role in mitigating GHG and air pollutant emissions associated with the livestock sector (Zhang et al., 2020a).A successful manure management system should not only reduce the pollutant gas emission, but also consider the economic cost and technical feasibility (Li et al., 2021).
Sep 18, 2019 · For 2012, preliminary results show a value of 15465.70 Gg CO2 eq from direct emissions, being 77.14% CH4 from enteric fermentation, 17.93% N2O from manure in pastures, 2.63% CH4 and 2.31% N2O from
Apr 29, 2023 · However, the study eventually found that anaerobic fermentation of 175 kg of cattle manure with 175 kg of water and 50 kg of poultry manure with 325 kg of water produced 6.33 and 0.83 m 3 /day of biogas, respectively (Recebli et al. 2015). 7.2.3 Characteristics and Composition of Animal Manure
Apr 15, 2024 · The objectives of this study are as follows: (1) to analyse the eco-efficiency of different modes with coupling crop and livestock production farms and optimize their economic efficiency and carbon emission intensity; (2) to explore the impact of farmland on the development of farms with integrated farming systems; and (3) to elucidate the coupling mechanism of the structure of the integrated
Jun 22, 2024 · consists of five parts: the control system, aeration heating system, compost fermentation system, discharging system, and rack. It features e fficient mixing and intelligent real-time monitoring and adjustment capabilities, allowing it to effectively complete the compost-ing and fermentation process of livestock and poultry manure.
Sep 1, 2024 · Livestock manure is a hotspot for antibiotic resistance genes (ARGs) and mobile genetic elements (MGEs), and an important contributor to antibiotic resistance in non-clinical settings. This study investigated the effectiveness and potential mechanisms of a novel composting technology, semi-permeable membrane covered hyperthermophilic composting (smHTC), in removal of ARGs and MGEs in chicken
Jul 1, 2023 · Wan et al. (2020) have built an aerated static box to increase efficiency and promote maturity in chicken manure fermentation by thermo-energy maintenance. Li et al. (2013) have conducted fecal fermentation by using an aerobic fermentation reactor with high chemical oxygen demand removal and restrained nitrogen loss.
Nov 29, 2022 · Anaerobic digestion is a clean and renewable energy technology that can effectively treat wastes such as livestock manure and agricultural straw (Ebner et al. 2016). Single feedstock anaerobic fermentation limits methane production to a certain extent due to its low biodegradability.
Jul 30, 2024 · Solid storage can be part of a manure management system with solid-liquid separation or manure drying but combining these practices is not required. Best Use Cases: Suitable for any animal type. Typical in colder climates; covered facilities can aid with snow and rainfall events.
Apr 2, 2024 · We used microbiology and molecular biology techniques to screen out high-temperature and low-temperature-resistant saprobiotics for compost and prepared a compound fermentation bacteria agent to rapidly ferment cattle manure into high-quality organic fertilizer in low-temperature season. Conventiona
Dec 15, 2022 · Ruminants have lower feed use efficiency than monogastric livestock, and produce higher reactive nitrogen and methane emissions, but can utilize human-inedible biomass through foraging and straw
Jul 1, 2018 · Ectopic fermentation system (EFS) is an effective technology for treating mass livestock manure. However, the associations between microbial communities and substance transformation remain Expand
Dec 16, 2023 · Enteric fermentation within the digestive systems of ruminant animals, such as cattle, sheep, and goats, is one of the primary sources of CH \(_{4}\) emitted from agriculture. During digestion, these animals have a distinct microbial ecosystem in their stomachs, where microorganisms decompose fibrous plant materials and produce CH \(_{4}\) as a metabolic byproduct.
Jun 22, 2024 · sheep manure compost at the end of fermentation, while whole ca le manure had a lower potassium content of 1.24%. Potassium is relati vely stable during the compostin g process,
Jun 3, 2017 · Ectopic fermentation system (EFS) is an effective technology for treating mass livestock manure. However, the associations between microbial communities and substance transformation remain
