2009/9/7/ · The H 2 production and carbohydrate removal in heat-treated, acid-treated, alkali-treated, and untreated food wastes are presented in Table 3.In all cases, CH 4 was not detected during the whole fermentation period. H 2 production rate and lag-phase time for the heat-treated, the acid-treated, and the untreated food wastes were derived using
2017/11/15/ · Lactic acid, a versatile platform molecular, could be bio-produced by synergistic fermenting food waste (FW) with waste activated sludge (WAS), which was a base consuming process and required a relatively longer fermentation time of 5 d at ambient temperature.To achieve high-rate lactic acid fermentation in a short time with
Food waste to various fermentation products is an emerging area of research, and therefore an in-depth understanding of all the aspects of food waste could help to overcome these
2020/1/1/ · 10.4. Enzymatic valorization of food waste for bioethanol production. Bioethanol is an alcohol synthesized during microbial fermentation, frequently from a substrate rich in carbohydrates, chiefly sugarcane, corn, sweet sorghum, or lignocellulosic biomass. Ethanol was considered as a potential substitute for gasoline.
2024/4/15/ · The food waste inflow into the anaerobic digestion system is 41,666 kg·h −1, where food waste undergoes conversion to CO 2 and CH 4 at rates of 2,655 kg·h −1 and 1,660 kg·h −1, respectively. The generated CO 2 and CH 4 are utilized in fermentation to produce biomass, from which 1,324 kg·h −1 lipid can be extracted, serving as the
2024/2/25/ · The substrate and the inoculum used in the fermentation experiments were collected from a treatment plant in Shenzhen, China. The food waste treated by the plant is sourced from restaurants and households. It comprises waste staples, vegetables, meat, and other constituents. This plant adopted a conventional two-phase anaerobic
2022/5/4/ · Food waste is a waste stream that is produced globally in huge amounts and therefore constitutes a major environmental concern. Additionally, the growing consumption of fossil fuels sets the need for alternative energy sources. To this end, in this paper, an holistic approach towards bioethanol production from source-separated food
2024/2/20/ · Furthermore, in practice, the content of alcohols and acids is not solely determined by the components of food waste. For instance, Feng et al. (2018) found that the primary component in the food waste fermentation broth is lactic acid when the pH ranges from 3.2 to 4.5. However, when the pH is between 4.7 and 6.0, the fermentation
2021/2/13/ · Hong and Haiyun optimized the co-fermentation of food waste and excess sludge, obtaining maximum VFA concentration of 29 g L −1 for 88% (VSS basis) food waste (Hong and Haiyun 2010). The synthetic food waste used in this study did not contain animal products, indicating that a certain amount of protein derived from the
2019/4/1/ · Co-fermentation of garden waste (GW) and food waste (FW) was assessed in a two-stage process coupling hyperthermophilic dark-fermentation and mesophilic anaerobic digestion (AD). (FCT) under the scope of the strategic funding of UID/BIO/04469/2013 unit and COMPETE 2020 (POCI-01-0145-FEDER-006684), Project
2021/8/31/ · The Special Issue will be focused on new food waste fermentation technologies and value-added products resulting from food waste fermentation. The main topics include, but are not limited to, the following: - New fermentation processes; - New food or feed production; - SCP production;
2023/8/5/ · In 2017, 2 billion tonnes of municipal solid waste was generated globally. In which 84% were collected, and only 15% was recycled 1.Approximately 60% of this waste stream is organic 2 and can be
2023/7/22/ · Solid-state fermentation is a tool that allows the development of microorganisms on solid or semisolid substrates in the absence of free water. This particularity allows agro-food waste to be used as fermentation substrates to generate various products such as the release of bioactive compounds, enzyme production, waste
Enzymatic pretreatment is an effective method which can improve the anaerobic digestion (AD) efficiency of household food waste (HFW). As an alternative to expensive commercial enzymes, mixed enzymes (MEs) produced in situ from HFW by solid-state fermentation (SSF) can greatly promote the hydrolysis rate of HFW and achieve advanced anaerobic
2023/7/7/ · Food waste is categorized as organic solid waste, which has a negative impact on environmental sustainability. Food waste was simultaneously used for the feasible generation of mixed volatile fatty acids (VFAs) and bio-hydrogen by deploying dark fermentation. Original anaerobic digested sludge was prepared via the shock technique …
