Sep 13, 2023 · Fermentation bed culture is a circular agriculture method commonly used in pig farming, referred to as breeding pig on litter, deep-litter-system, or in situ decomposition of pig manure (Morrison et al. 2007). Pigs are raised on a fermentation bed, and the manure is decomposed in situ. While this method reduces the environmental impact of
Dec 7, 2022 · In this study, we investigated the inhibitory effect of low temperature on biogas fermentation system. Biogas fermentation inoculum was domesticated at 4 °C, and subsequently inoculated into pig manure feedstock in a batch biogas fermentation process. A low-temperature biogas fermentation system was maintained at 9 °C, and its abiotic factors
Feb 20, 2024 · To address these challenges, the fermentation bed culture has emerged as a circular housing system for pig farming (Xu et al., 2022). It is known as the deep-litter-system, breeding pig on litter, or in situ decomposition of pig manure (Morrison et al., 2007). In this system, pigs are raised on a thick layer of fermentation bed, which is
Oct 15, 2022 · Pig manure is rich in protein and other nitrogen substances, with a low C/N (Söderftröm et al., 2002). The fermentation using pig manure as sole substrate can easily cause an ammonia suppression, which is unfavorable to biogas production and leads to poor composting efficiency (Shen et al., 2018).
Sep 10, 2022 · This study compares the physicochemical properties, lignocellulose degradation, microbial community composition, and carbohydrate-active enzymes (CAZymes) in ectopic fermentation systems (EFS) of pig manure mixed with either conventional padding (C) or straw waste (A).
Nov 9, 2017 · Background Pig manure utilization and valorization is an important topic with tightening regulations focused on ecological and safety issues. By itself pig manure is a poor substrate for biogas production because of its excessive nitrogen content relative to available organic carbon. Such substrate is alkaline, and methanogenesis can be suppressed, and so additional substrates with high
Jan 1, 2021 · Request PDF | Microbial community and function in nitrogen transformation of ectopic fermentation bed system for pig manure composting | In this work, agricultural wastes were treated by
Dec 20, 2023 · In this study, three typical pig manure treatment and disposal routes: pig manure solid-liquid separation, i) wastewater biological treatment, direct land application of manure/sludge; ii) black-film anaerobic digestion of wastewater, mono-composting of manure/sludge and land use; iii) wastewater biological treatment, co-composting of manure
Jun 13, 2023 · This study established an anaerobic fermentation system using pig manure/corn straw as substrate to compare the influence on biogas production and Cu and Zn passivation by humic acid (HA), biochar (BC), fly ash (FA), and zeolite (ZS). Results showed that the cumulative gas production was promoted, and the availability of Cu and Zn was decreased substantially with the introduction of
Jul 1, 2023 · To stringently simulate the stable fermentation process of EFS, a pig manure slurry ectopic fermentation was lasted for 66 days in experiment 1. This study compared the change of EFS indicator by using different padding materials under the CMA intervention first.
Jun 3, 2017 · Overproduction of livestock manures with unpleasant odors causes significant environmental problems. The microbial fermentation bed (MFB) system is considered an effective approach to recycling utilization of agricultural byproducts and pig manure (PM).
Dec 7, 2022 · The biogas fermentation raw material used in this study was fresh pig manure, which came from a large pig farm in Fumin County, Kunming City, China. The total solid ( TS ) of the pig manure was
Jan 1, 2023 · The objective of this study was to optimize the process parameters of the anaerobic co-digestion of pig manure and rice straw to maximize methane production and system stability. In this study, batch experiments were conducted with different mixing ratios of pig manure and rice straw (1:0, 1:1, 1:5, 1:10, and 0:1), total solid concentrations (6%, 8%, 10%, 12%, and 14%), and inoculum accounts
Mar 14, 2024 · Whether advanced biological waste treatment technologies, such as hydrothermal pretreatment (HTP) integrated anaerobic digestion (AD), could enhance the removal of different antibiotics remains unclear. This study investigated the outcome of antibiotics and methane productivity during pig manure treatment via HTP, AD, and HTP + AD. Results showed improved removal efficiency of sulfadiazine
