2011/1/1/ · Abstract. “Biogas” is the name popularly used to denote the flammable mixture of gases that are generated when organic material undergoes anaerobic decomposition. The mixture contains 40–70% (usually 55–65%) methane, carbon dioxide, and traces of other gases. “Biogas” has good calorific value and can be directly used as
2019/10/5/ · The effects of temperature, moisture content and germination index of seeds in the aerobic composting were analyzed. Besides, the effects of sugarcane leaves in different ratios were investigated in the aerobic composting of the biogas residue. The results showed that the maintenance of the high temperature for the fermentation of
Fermentation 2022, 8, 523 2 of 15 compost products, thereby increasing the added value of fertilizer utilization of biogas residue [4]. However, due to the use of additives in livestock and
2022/12/1/ · The resource usage of biogas residue may be realized by composting and biochar generation of biogas residue, however there are certain issues. For example, biogas residue has a high moisture content, and pyrolysis of biogas residue to make biochar needs a lot of energy, limiting energy recovery and wasting non-renewable
Conclusion: Resultantly, an initial C/N ratio of 37.7/1 could be suggested in the aerobic co-composting of biogas residue with mango by-products. Research Highlights · Co-composting of mango by-products and biogas solid residue eliminates some of the weaknesses of composting these wastes separately. · The incubation period determined
Fermenter for bio-fertilizer production is a complete set of equipment specialized in handling organic waste such as animal and poultry manure, food waste, and domestic waste.To realize resource utilization of organic waste, the organic matter is biodegraded and decomposed by the activity of biomass in high-temperature aerobic fermentation, so
2024/1/1/ · Anaerobic fermentation to produce biogas is a microbial-driven process, with various species acting in different stages of the conversion of input material
2022/10/8/ · The treatment of biogas residue after anaerobic fermentation by aerobic composting can effectively improve the shortcomings of direct digestion, and improve the quality of compost products, thereby increasing the added value of fertilizer utilization of biogas residue . However, due to the use of additives in livestock and poultry breeding,
Anaerobic Digestion in a Biogas Digester is the process in which bacteria biodegrade organic materials – such as solid animal manure, bio waste, and food waste – in the absence of oxygen (o2). Biogas production in a Biogas Digester is done in gas-sealed units called digesters, which are designed and built in different forms and sizes
2024/1/1/ · Biogas is obtained in a suspended monoxide decomposition process by anaerobic bacteria or in a fermentation process of decomposable materials such as agricultural manure, sewage, municipal waste, green waste (gardens and parks), plant
2022/8/1/ · The results revealed that N 2 O release mainly occurred during the second fermentation phase. Biogas residue amendment promoted N 2 O emission, 2021). Aerobic composting can convert crop straw and livestock manure into high-quality organic fertilizer to meet the objective of resource cycling of agricultural waste (Chen et al., 2020,
2021/2/13/ · 2.2 Biochar production. Details on BR preparation have been reported previously (Zheng et al., 2018).For biochar production, oven-dried BR samples were placed inside capped porcelain crucibles and loaded into a muffle furnace (KSL-1200X, Kejing Materials Tec.) under N 2 (99.999%) saturated atmosphere (0.5 dm 3 min −1 of flowing …
