May 3, 2024 · Donghaifeng livestock farm adopts vertical anaerobic fermentation equipment, with pig manure and urine as the main source, to add agricultural waste or distiller’s grains as a source of co-digestion. The system converts these wastes into biogas energy and organic fertilizer to achieve energy and resource recycling.
Sep 15, 2023 · The effective conversion and recycling of organic solid waste contribute to the resolution of widespread issues such as global environmental pollution, energy scarcity and resource depletion. The anaerobic fermentation technology provides for the effective treatment of organic solid waste and the generation of various products. The analysis, which is based on bibliometrics, concentrates on the
Mar 24, 2022 · This has implications for the agricultural sector of any economy since agro-industrial wastes have huge potential for the production of biofertilizers through microbial biotechnology and solid-state fermentation as a safer, inexpensive alternative to chemical fertilizers to improve agricultural yields of crops.
Feb 24, 2024 · Agriculture intensification for production of more food to feed an increasing global population, as a consequence, generates a large volume of agricultural waste. The agro-waste, which is biochemically composed of cellulose, lignin, and hemicellulose, is frequently
The fermentor uses natural anaerobic degradation and decomposition of organic matter, for example, manure from poultry or agricultural waste, under controlled conditions to produce biogas [22].
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).
Dec 12, 2022 · Solid-state fermentation (SSF) is part of the pathway to consolidate waste as a relevant alternative for the valorization of organic waste. The objective of SSF is to produce one or several bioproducts of added value from solid substrates. Solid-state fermentation can use a wide variety of organic waste as substrates thus, it is an excellent candidate in the framework of the circular
Direct Combustion - This makes use of agricultural residues such as rice-hull from the mill, cogeneration using coconut shell, bagasse in sugar mills, kiln-drying of lumber, tobacco-curing, bakeries and other industries for the generation of electrical and heat energy.
Agricultural waste are plant residues from agriculture. These waste streams originate from arable land and horticulture. Agricultural waste are all parts of crops that are not used for human or animal food. Crop residues consist mainly of stems, branchs (in pruning ), and leaves. [1] It is estimated that, on average, 80% of the plant of such
Jun 23, 2021 · Fermentation is a multi-disciplinary concept that is defined from the perspectives of various disciplines. It connotes different meanings to microbiologist, biochemist, food and nutritionist (rumen modulator/manipulation) and soil scientist. However, the overall is that it results in the breakdown of substrates (organic or inorganic) in the absence of air to yield intermediate by-products
Jan 30, 2024 · Vertical farming has emerged as a critical solution for sustainable urban development, addressing pressing issues of food security and environmental concerns. This innovative approach to agriculture involves cultivating crops in vertically stacked layers, using advanced technologies such as hydroponics and aeroponics.
Aug 9, 2021 · Just eight technologies, including precision fermentation and cellular agriculture, can directly eliminate over 90% of net greenhouse gas emissions worldwide within 15 years, according to think tank RethinkX.
Feb 19, 2020 · For sustainable agriculture, it is important to manage agricultural wastes, such as crop residues and livestock wastes. Anaerobic digestion has been gathering the attention to recycle these wastes into renewable energy (biogas) and fertilizer (soil amendment) (digestate). Dry anaerobic digestion is defined as digestion at higher than 20% of total solid (TS) content in the reactor, which is
Apr 1, 2024 · Several industries (such as food modification, pharmaceutical sectors, agro-industrial waste transformation, biofuel production, and laundry industries) used microbial fermentation (known to be a bio-based fermenter) in bioreactors to produce value-added products.
Apr 1, 2023 · The dry AD system is designed primarily to treat solid organic wastes, including agricultural residues, industrial waste, municipal solid waste, and energy crops and plants, as shown in Fig. 2.
