Jan 30, 2024 · Solutions. Anaerobic digestion (AD) of poultry manure in the United States (U.S.) has many environmental and economic benefits, including renewable energy production and reduced greenhouse gas emissions. Poultry manure is the nation's third largest source of methane from livestock manure management (see Figure 1). Figure 1.
Nov 29, 2023 · Utilizing poultry and livestock manure for anaerobic fermentation is an excellent solution for the large-scale treatment of agricultural waste, reducing emissions, and lowering pollution risks.
Nov 1, 2020 · The objective of this study is to examine the viability of recycling olive industry wastes by co-composting with poultry manures, describe the evolution of the physic-chemicals and microbiological
fermentation in domestic livestock, livestock/poultry manure management, agricultural soil management, field burning of agricultural residues, and rice cultivation. The U.S. EPA (2021) estimated that, in 2019, the agriculture sector was responsible for 9.6 percent of total U.S. GHG emissions. Even though the contribution of agriculture is
Jul 1, 1984 · Two major recognized problems are: 1) the physical handling of the manure prior to and during fermentation and 2) the accumulation of potentially toxic substances during the biodegradation process (Rockey et al, 1978; Bery et al., 1978). Of the major manure types, swine manure most closely resembles poultry manure.
Sep 1, 2021 · In order to explore the effects of adding biochar on biogas production by high solid concentration anaerobic fermentation of livestock and poultry manure and agricultural safety, this study used pig manure, cow manure and chicken manure as fermentation raw materials, and carried out experiments on biogas production by mesophilic temperature anaerobic fermentation with high solid concentration.
Dec 1, 2022 · Therefore, it can be concluded that the co-fermentation of sewage sludge, wine vinasse and poultry manure, was suitable and appropriate to obtain biohydrogen with the highest yields at 5 days HRT. With these optimal conditions it is possible to complete the process with a second methanogenic stage to obtain biomethane or to obtain PHA from the
Nov 28, 2017 · Livestock and poultry breeding industry is one of the main economic pillars of northeastern China. However, the amount of pollutants produced is much higher than that in other parts of China. Through a questionnaire survey, indoor experiment, and outdoor experiment, it was found that the resource utilization rate of livestock and poultry manure in the northeastern region is low, with the
Nov 12, 2021 · Traditional chicken manure fermentation is mostly natural composting or exposure, which is not only time consuming but also susceptible to weather, resulting in uncontrollable quality and environmental pollution. This research aims to build a smart solar chicken manure fermentation system to control the conditions of chicken manure fermentation effectively, improve quality, and solve the
Feb 15, 2022 · Volume 139, 15 February 2022, Pages 124-135. Integral approach for the evaluation of poultry manure, compost, and digestate: Amendment characterization, mineralization, and effects on soil and intensive crops. Author links open overlay panel.

Various advanced technologies have been utilized to treat the livestock and poultry manure, and wastewater in the breeding industry in recent years. This study aims to better track the progress of the treatment and utilization of manure and wastewater. A nationwide survey was conducted from 2018 to 2020, covering 3 162 pig, cattle, and poultry farms. The technical pathway and facility
Dec 15, 2023 · In the past, this was a common and fast method for handling chicken manure on farms. With the development of mechanization and industrialization, wastewater treatment equipment in aquaculture has become increasingly advanced. Fermentation-based chicken manure treatment is currently widely used. 1. Sealed Fermentation Tanks
May 6, 2021 · Distribution of Antibiotics and Antibiotic Resistance Genes in Animal Manure. The environmental pollution caused by antibiotics and their ecotoxicological effects has become a major global problem, especially the environmental pollution caused by the abuse of antibiotics in the livestock and poultry industry [5,6,7,8], which has become one of the current international research hotspots [].
May 5, 2023 · The objective of this work was to determine the potential of chicken manure as a substrate for biogas production after pretreatment. The effects of removing excess nitrogen from chicken manure by water extraction in a temperature range from 20 °C to 60 °C to increase methane production were investigated. The dynamics of the process and efficiency of biogas production were also analyzed. As a
The content of undigested crude protein in animal manure is very high, the content of protein in air-dried chicken manure is 24–30%, in pig manure is 3.5–4.1%, and in cow manure is 1.7–2.3% . In the face of the severe contradiction between supply and demand of protein feed, livestock manure is a potential feed resource.
