Feb 8, 2022 · Biogas anaerobic fermentation refers to the organic material (such as people and livestock poultry manure, straw and weeds, etc.) in a certain moisture content, temperature, and anaerobic conditions through various kinds and the function of different kinds of microbe catabolism, eventually mixtures, such as the formation of methane and carbon dioxide gas (methane) complex biochemistry process.
Oct 8, 2020 · In this regard, the aim of this work was to achieve the production of biogas using the dry anaerobic technology through livestock manure co-digestion with agricultural waste (AW) such as potato peels, lettuce leaves and peas peels.
Jan 18, 2022 · As an effective treatment technology for livestock farming wastes, the ectopic fermentation bed system (EFS) provides a new means of treating human waste and producing organic fertilizer from
Sep 15, 2023 · The two-stage process can not only remove the VFAs in the fermentation waste liquid, but also generate clean and easy-to-use biomass energy at the same time. However, the performance of the system in long-term operation and its process economy still need to be further studied.
Jan 1, 2021 · The unique way to manage animal waste is the digestion of anaerobic materials because they can provide positive benefits related to many problems, including green energy and water contamination [2]. In protecting the environment and efficiently recycling agricultural systems, anaerobic digestion of animal manure is widespread.
Apr 29, 2023 · 12.1.1 Concept of Sustainability. The definition of term sustainable is “which can be sustained throughout time” (Heinberg and Lerch 2010).To start with the term’s etymology, the word sustainable or sustainability has its origin in the Latin word sustinēre formed by combination of words sub and tenēre that means to “maintain,” “support,” “endure,” or “to restrain
Jul 13, 2024 · Furthermore, high-quality biogas systems have been recognized as the most efficient strategy to reduce methane emission of organic waste treatment 12. With manure treatment alone, it could reach 6
Apr 18, 2024 · The efficient and eco-friendly management of livestock waste is crucial to agricultural sustainability. Livestock farming is an integral part of the global food production system.
Jul 28, 2023 · Anaerobic fermentation (AF) can effectively dispose of kitchen waste (KW) without the shortcomings of traditional such as incineration and sanitary landfill. However, KW has a high organic content, which easily leads to acidification and ammonia inhibition during digestion. To mitigate this issue, anaerobic co-digestion (AnCoD) with other substrates helps to adjust the carbon to
May 31, 2023 · To break the bottlenecks of slow hydrolysis and low acid production efficiency of waste-activated sludge (WAS) in the traditional anaerobic fermentation process, this study investigated the employment of ferrous-iron (Fe(II))-activated sulfite to produce hydroxyl, sulfate, and other highly oxidizing radicals on WAS floc cracking and short-chain
Nov 29, 2023 · Anaerobic fermentation of organic waste, such as livestock manure, in biogas projects is an environmentally friendly and effective treatment method.
Apr 15, 2020 · Previously, the domestic waste in rural areas was mainly kitchen waste, and the surplus kitchen waste was used to raise livestock, and the manure produced by livestock was mostly returned to the field as organic fertilizer (Xu et al., 2017). The construction of new socialist countryside has changed the traditional life mode in the countryside
Apr 10, 2020 · According to the influences of temperature on microbial activity, the anaerobic fermentation can be divided into four temperature ranges, i.e. low-temperature fermentation at 15–20 °C, moderate-temperature fermentation at 30–35 °C, high-temperature fermentation at 50–55 °C and ultra-high-temperature fermentation above 70 °C.
Unlocking the metabolic nuances between high and low feed efficiency animals can pave the way for more sustainable and efficient beef production systems. It’s evident that while foundational knowledge has been established, there is still much to unearth in understanding the rumen metabolome and its impacts on ruminant production.
Composting or aerobic fermentation is an effective way to treat agricultural waste and produce organic fertilizer. Improving the application rate of organic fertilizer in soil needs time to reduce dependence on chemical fertilizers.
