The aim of this study was to determine the possibilities of methane fermentation of the poultry manure in the mixture of the most popular input for biogas plants that is maize silage. The obtained results show that fermentation of the poultry manure without any additives gives l
Oct 31, 2019 · The kinetic coefficients of biogas production and of organic matter content loss during fermentation of GW alone were lowest (0.27 ± 0.01 d ⁻¹ , 0.36 ± 0.02 d ⁻¹ ), they increased as the
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.
Nov 29, 2022 · Purpose To explore the methane production potential and microbial community changes of combined anaerobic digestion of chicken manure and corn straw. Increase methane production, reduce the environmental pollution caused by the burning of livestock manure and straw, and provide some theoretical references for the construction and operation of actual biogas projects. Different
Nov 11, 2022 · This study comprehensively explored the process of acidogenic fermentation from chicken manure and in situ recovery of VFA from the reactor media in a high-solid AnMBR. Thermally shocked CM was proved to have great potential to be used as both inoculum and substrate for sustainable VFA production.
Jun 1, 2013 · With the increase in intensive and mechanized poultry breeding industries, large amounts of waste are being produced. Annually, about 13 million tons of chicken manure (CM) is generated in Japan, which corresponds to 0.65 times the total food processing waste (MAFF, 2008). Since the organic matter in CM is highly biodegradable, methane
Jul 18, 2023 · As a result of manure fermentation after pretreatment, 16 to 45% more biogas and 18 to. 39% more methane were obtained compared to manure without pr etreatment. The effect of extrac-. tion was to
Jun 12, 2023 · The total biogas yield decreased from 450.4 to 211.0 mL/g volatile solids in the presence of Staphylococcus aureus and chlortetracycline in chicken manure. A chlortetracycline concentration of 60
Sep 1, 2021 · The results showed that the addition of biochar had different effects on anaerobic fermentation of livestock and poultry manure with high solid concentration, increased the content of CH4 and decreased the content of H 2 S. the addition of biochar provided enough granular surface to absorb a large number of inoculated microorganisms, which
A study by Salyuk et al. indicated the negative effect of increased glycerin concentration obtained after biodiesel production, on chicken manure co-fermentation at 35 to 55 °C. The substrate with the ratios of chicken manure to glycerol of 9:1, 8:2, and 7:3 at TS contents equal to 26, 22, and 18%, respectively, were used to provide fermentation.
Jan 10, 2014 · The total production of biogas from poultry manure during the period of 58 days of fermentation amounted to 319 dm 3 /kg d. m. For waste mixtures, it grew together with an increase in the
The rise in poultry production has increased rapidly, accompanying the global surge in food demand. Consequently, chicken manure (CM) production has significantly increased to meet the demand for chicken products. It is estimated that approximately 80–100 g of CM is produced daily by one chicken (Manogaran et al., 2022). This substantial CM
Aug 13, 2016 · In this study, single-stage and two-phase semi-continuous thermophilic anaerobic reactors fed with diluted (3 % total solids (TS) and 1.8 % volatile solids (VS)) chicken manure at three different hydraulic retention times (HRTs) were compared interms of biogas production rate, methane content of the produced biogas, and VS and TS removal. Along the study, HRTs of 16, 12, and 8 days were
Feb 18, 2023 · Therefore, if poultry manure is fermented in an air-tight bag in an anaerobic condition with a fermentation mixture of PM (90%) and molasses (10%) inoculating 10% IMO at least for 7 days, it can
May 2, 2022 · Batch experiments were performed to evaluate the biohydrogen and biomethane production by co-digestion of chicken manure and food waste in a two-stage mesophilic fermentation process. Results showed that no hydrogen was produced in the first stage of sole chicken manure fermentation, while methane yield was 247.3 mL·g−1-VS. By comparison, the co-digestion process with food waste proportions
