2022/10/1/ · 1. Introduction. As urbanization and its population continue to grow, food waste (FW) and sewage sludge (SS), two solid waste as by-products, are produced in large quantities (Liang et al., 2021).For example, in Hong Kong, it is reported that over 1,300,000 tons FW are produced per year (Luo and Wong, 2019).With regard to SS, the corresponding
2018/5/22/ · Fermentation distilleries produce a considerable volume of high-strength wastewater, known as stillage, having unconvertible organic fractions, lower pH and high percentage of dissolved organic and inorganic matters. Molasses stillage comprises higher level of chemical oxygen demand of 80–140 g/l, biochemical oxygen demand of 40–65 g/l,
2020/4/23/ · Whiskey distillery waste streams consisting of pot ale (liquid residue) and spent grain (solid residue) are high strength organic wastes and suitable feedstock for anaerobic digestion (AD) from both economic and environmental stand points. Anaerobic digestion of pot ale and pot ale/spent grain mixtures (with mixing ratios of 1:1, 1:3, and 1:5
2022/12/23/ · AAD, which is also referred to as acidogenic fermentation or arrested methanogen-esis, has been tested on various complex wastes such as sewage sludge [20], livestock waste [21], food waste [22], press mud [23], dairy wastewater [24], and corn stover [25,26] and described in several reviews [27–29]. As with any biochemical process, the
Alcohol production (stage I: feed preparation; stage II: fermentation; stage III: distillation; stage IV: packaging). As can be seen in Figure 1, there are two types of waste generated in a distillery: process waste and non‐process waste. Non‐process waste is
2021/7/15/ · The usage of Distillery waste reduced greenhouse gas (GHG) emissions by 54% directly and indirectly up to 41% by replacing the synthetic fertilizer that are being used to cultivate barley consumtion by a distillery.
2020/6/1/ · Recently, an optimization study of a full-scale (effective volume of 11,000 m 3) anaerobic CSTR from distillery spent wash with extreme high COD (110–140 g·L-1) was
2015/9/15/ · Anaerobic digestion is a series of biological processes in which microorganisms break down biodegradable material in the absence of oxygen. One of the end products is biogas, which is combusted to generate electricity and heat, or can be processed into renewable natural gas and transportation fuels. A range of anaerobic digestion
fermentation (Covaliov V., Ungureanu D. et al. 2012). At the same time, anaerobic fermentation of organic substrates in waste waters from the aforementioned industries can be not only the way to reduce the pollutants contents, but the source of biogas as well. A variety of biomass resources can be used to convert to energy.
