Dec 1, 2023 · Composting is a feasible and promising method for converting organic solid waste, including manure, sludge, and kitchen waste, into organic fertilizers or soil amendments to improve crop growth (Yang et al., 2023a, Zhao et al., 2022a, Zhao et al., 2022b, Wang et al., 2021, Zhan et al., 2022).

In reality the manure processing consists of three steps. The manure is first fermented. In fermentation, manure is brought into a heated tank, where bacteria break down a part of the biomass and produce biogas. The digestate is then separated into a thick and thin fraction. Finally, the thin fraction goes to the manure processing plant.

Sep 15, 2021 · 1. Introduction1.1. Livestock waste production and the resulting environmental impact. According to a recent report, world population has doubled in the last 40 years and reached 7.7 billion in 2019; with a current growth rate of 1.08% per year the population is estimated to reach 9 billion by 2037 (Max et al., 2019).

Nov 29, 2023 · organic wastewater and poultry and livestock manure. The common treatment for livestock manure are composting and biogas engineering. They can be classified according to Table1. Aerobic fermentation has the advantages of a fast fermentation rate and rapid microbial proliferation. Anaerobic fermentation requires less space and allows

Jun 12, 2023 · Adopting waste-to-wealth strategies and circular economy models can help reduce biowaste and add value. For instance, poultry farming is an essential source of protein, and chicken manure can be converted into renewable energy through anaerobic digestion. However, there are a number of restrictions that prevent the utilization of chicken manure in bioenergy production. Here, we review the

Nov 12, 2018 · Impact of Livestock on Climate Change. The most important greenhouse gases from animal agriculture are methane and nitrous oxide. Methane, mainly produced by enteric fermentation and manure storage, is a gas which has an effect on global warming 28 times higher than carbon dioxide. Nitrous oxide, arising from manure storage and the use of

Oct 1, 2012 · Fermentation yielded 670 NL biogas/kg volatile solids (VS) with the CSTR and 550 NL biogas/kg VS with the FBR. The productivities were 3.9 NL biogas/ (L*d) with the CSTR and 3.4 NL biogas/ (L*d) with the FBR. The average methane concentration was approximately 60% for both reactor systems.

Sep 15, 2023 · The traditional industrial production of lactic acid mostly takes whey, molasses, starch waste, sugar beet, sucrose and carbohydrate-rich materials as substrates for fermentation. It can obtain high-purity lactic acid products, and the cost of raw material pretreatment and lactic acid separation and purification is low.

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.

Jan 1, 2022 · The increase in solid waste has become a common problem and causes environmental pollution worldwide. A green approach to valorise solid waste for sustainable development is required. Agricultural residues are considered suitable for conversion into profitable products through solid-state fermentation (SSF).

Feb 1, 2024 · Lastly, the present work has critically reviewed the role of MCF in bio-H 2 production via the various dark fermentation pathways from varieties of agro-industrial waste types. The challenges associated with each of those DF pathways and the strategies to overcome those challenges to generate greater yields and productivity have been critically

Jan 2, 2024 · Among the total number, during fermentation, 140 bacterial species (86%) increased in the solid samples with higher OM content; however, 122 bacterial species (75%) decreased in the liquid

39.4.2.3 Fermentation of food wastes. The compositional variation is one of the challenges in food waste fermentation. Recently, Poe et al. (2020) studied the influence of compositional variation of food waste on butanol production through fermentation. They collected dining hall food waste weekly for 16 weeks.
