Due to the high demand for food and meat for the world's growing population, the agricultural sector is expanding every year. Timely and effective treatment is of utmost importance to utilize organic matter in agricultural waste and avoid environmental pollution. Composting or aerobic fermentation is an effective way to treat agricultural waste and produce organic fertilizer. Improving the
Apr 19, 2023 · where Mprop nutr,(j) is the proportion of manure nutrients within total input (only considering chemical and manure input) for each county (or each crop); TM nutr,in,(j) is the total manure
Rajagopal et al. [ 62] investigated chicken manure fermentation (with straw) at a TS concentration of 30%. Anaerobic digestion with a loading rate of 5.4 g VS/ (kg inoculum*day) and 21.6 g VS/ (kg inoculum*day) at 20 °C was conducted. The authors reported that methane yield was lower at a higher loading rate.
Feb 1, 2015 · The effects of ammonia concentration on the performance and stability of mono-fermentation of chicken manure were investigated in a lab-scale continuous stirred tank reactor at 40 °C. Technical stripping was performed to remove ammonia from the liquid fraction of digestate, and the entire product was recycled to the fermenter to control
Jun 1, 2013 · 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 fermentation is considered the best method to minimize waste and recover bioenergy.
Mar 1, 2009 · The effect of temperature on production of ammonia during dry anaerobic fermentation of chicken manure (CM), inoculated with thermophilic methanogenic sludge, was investigated in a batch condition for 8 days. Incubation temperature did not have a significant effect on the production of ammonia. Almost complete inhibition of production of methane occurred at 55 and 65°C while quite low yields
Nov 11, 2022 · Acidogenic fermentation of chicken manure (CM) for production and recovery of volatile fatty acids (VFA) is an interesting biological waste-to-value approach compared to benchmark organic waste management strategies. Considering the wide range of high value applications of VFA, a semi-continuous immersed anaerobic membrane bioreactor (AnMBR) was applied to boost VFA productivity and yield
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
Abstract. This paper performs a batch experiment for pre-acidification treatment and methane production from chicken manure by the two-stage anaerobic fermentation process. Results shows that the acetate was the main component in volatile fatty acids produced at the end of pre-acidification stage, accounting for 68% of the total amount.
Apr 1, 2024 · Abstract. Sludge and chicken manure anaerobic co-fermentation is an effective way to obtain volatile fatty acids (VFAs). Aimed at exploring the effects of co-fermentation on VFAs production and microbial characteristics, six experimental groups with different pH were set up.
Jan 29, 2021 · 1~1.5 tons of dry chicken manure (about 2.5~3.5 tons of fresh chicken manure) needs one kilogram of chicken manure starter. And 5~10 kg of rice bran, corn or bran need to added to each kg of starter. After mixing well, you can sprinkle them in ready raw materials. Step 2: Adjusting C/N
Mar 7, 2024 · The Benefits of Chicken Manure. As a non-synthetic organic fertilizer, chicken manure has numerous benefits. Nutrients: It is a complete fertilizer that contains the macronutrients nitrogen, phosphorus, and potassium, as well as important micronutrients such as calcium needed for healthy plant growth. Soil amendment: Chicken manure is more than
Nov 12, 2021 · After around 50 h, chicken manure formed small particles which were assumed to reach a dry and powdery state. Germination efficiency was determined by culturing seeds with fermented fertilizer of chicken manure. It was found that the fermented fertilizer could grow faster compared to the control group. 2. System Design 2.1.
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
Oct 18, 2023 · Free volatile fatty acids (free VFA) play a crucial role in the inactivation of pathogens during the anaerobic digestion of animal manure. However, the decomposition of nitrogenous components can release alkaline ammonium-N, which might increase the pH and reduce the concentration of free VFA. In this study, continuous anaerobic digestion of high-solid chicken manure was conducted for 150 days
