Aug 9, 2019 · Solid-state fermentation (SSF) is, by definition, a technology carried out in absence or near absence of free water. Therefore, it allows the use of solid materials as substrates for further biotransformation. SSF has gained attention in the last years being reported as a promising eco-technology that allows obtaining bioproducts of industrial interest using solid biomass (wastes and by
Dry Fermentation of organic waste and manure. Dry fermentation (SSAD) in a biogas plant involves the fermentation of organic feedstocks to produce biogas under anaerobic conditions (without atmospheric oxygen). The solid fermentation plant consists of drivable, gas-tight, and acid-resistant concrete fermenter boxes, which are filled and emptied
This review article presented the current status and traditional agricultural waste (livestock manure and crop straws) utilization , the art of aerobic fermentation process including ultrahigh temperature fermentation and composting.
Jan 1, 2018 · Waste bread: Continuous anaerobic fermentation using sludge: 109 mL/g FW Han et al. (2016b) Pineapple waste: Anaerobic mixed culture fermentation: 77.3 mL H 2 /g volatile solids: Reungsang (2013) Mixed fruit peel waste: Continuous fermentation using up-flow anaerobic contact filter: 42.8 mL H 2 /g FW d: Vijayaraghavan et al. (2007) Banana peels
The fermenter consisted of a large cylindrical tank with air introduced at the base via network of perforated pipes. In later modifications, mechanical impellers were used to increase the rate of mixing and to break up and disperse the air bubbles (Fig. 20.1). This process led to the compressed air requirements.
The abundance of organic solid waste throughout the world has become a common issue that needs complete management at every level. Also, the scarcity of fuel and the competition between food and substance as an alternative to a petroleum-based product has become a major problem that needs to be properly handled. An urge to find renewable substances for sustainable development results in a
Oct 1, 2012 · The general idea to use food waste as a co-substrate for treating materials, whose biodegradability need improvement, can be confirmed by our examinations. Although in this study food waste (consisting of different waste kinds, see 2.1 Substrate) as single substrate was anaerobically digested, the results allow the mentioned assumption.
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.
Jan 28, 2021 · Food waste poses a serious threat to the planet. In the U.S. alone, as much as 50% of all food is thrown away. Most of this waste isn't recycled, but instead, takes up more than 20% of America's
The Association for Waste Management Kempten put a biomass treatment plant into operation in 2019. Technology worth about €2.8 million in total ensures that foreign matter is optimally removed from organic waste and green waste to prepare it for fermentation. A BHS-Sonthofen Biogrinder is now used to process and shred this material.
Mar 8, 2022 · A fermenter (bioreactor) is a closed vessel with sufficient aeration, agitation, temperature, and pH regulation arrangements and a drain or overflow vent to extract the waste biomass along with its products from cultured microorganisms. The fermenter is intended for the production of biological products.
Apr 16, 2020 · Corn straw, pig manure, and kitchen waste were selected as solid wastes of agricultural biomass. A system including a temperature control device, a fermentation device and a gas gathering device is used to measure the content and pH value of biogas and methane. Physical, chemical, and biological pretreatment were used to strengthen the
Semisolid fermentation: In semisolid fermentation, the substrate is usually used in solid state e.g. cassava waste . The cultivation involves many operations which include stirring and mixing of a multiphase system; transport of oxygen from the gas bubbles through the liquid phase to the microorganisms; and the process of heat transfers from
On a global scale, one of the major food waste is bread, reaching thousands of tons daily. Industrial bread waste is generated at different stages: during the manufacturing process, because of substandard products or other processing factors such as crusts removal for sandwich bread production, or as unsold bread from retail ( 106 ).
VFAs. Imported organics (food waste, fats, oils, and grease, etc.) could also be used as feedstock for a fermenter, but operator attention is required in the handling of the additional load to the fermentation system. In one instance, molasses was used to increase a fermenter VFA yield (Thomas et al. 2003).
