2013/11/30/ · The controlled environmental conditions resulted in butyrate being the main metabolite that suppresses lactic acid and propionic acid production in food waste and food processing waste fermentation. When butyrate is the end-product, a theoretical maximum of 2 mol H 2 per mole of glucose is obtained: (2) C 6 H 12 O 6 + 2 H 2 O → CH

2020/10/28/ · Food waste has a great potential for resource recovery due to its huge yield and high organic content. Oriented fermentation is a promising method with strong application prospects due to high efficiency, strong robustness, and high-value products. Different fermentation types lead to different products, which can be shifted by adjusting

2022/8/2/ · Food waste for bio-fertilizers production. Production of bio-fertilizers from food wastes via anaerobic digestion (AD) method is the most common and frequently applied process (Chen et al., 2012). In various uses of industrial production & application, bio-fertilizer is a common byproduct.

2022/4/6/ · Recycling and transformation of food wastes represent a great opportunity in supporting sustainable development by their conversion into value-added products through the fermentation process. 1. Food Waste Valorization. Food waste is becoming a growing and important concern at both local and global levels [ 1, 2 ].

2020/2/11/ · The food waste composition is illustrated in Figure 2, and the fermentation process was modeled in an open anaerobic condition with ethanol yield as 2.2% (w/w) wet basis without any enzymes. The FW conversion and ethanol yield were taken from the experimental study done by Muhammad [ 8 ].

2024/4/1/ · Food waste anaerobic digestate (FWAD) Chongqing, China. About 150 t/d of FWAD was generated in the plant. The fermentation liquor of the complex microorganisms mainly composed of some bacteria such as ... Excessive accumulation of aged sludge in the activated sludge tank, and low bio-activity of activated sludge in the

2020/3/1/ · Valorization of food waste is a preferential strategy for food waste management. Biofuel and bio-electricity production using food waste reduces environmental burden. With the changing life-style and rapid urbanization of global population, there is increased generation of food waste from various industrial,

2024/4/1/ · According to the United States Department of Agriculture (USDA), 87% of worldwide soybean production is converted into soy cake and soy oil. In comparison, just 6% are utilized for human consumption, including tofu (44%), soy milk (35%), and other products (20%) (Guimarães et al., 2018).Tofu has surpassed other soy-based products to become

2012/8/1/ · The lower part of the table shown the physical–chemical characterization of the substrate fed to the dark fermentation reactor. As shown in Table 1, the food waste collected has a relevant content of fruit and vegetables (38–46% on wet weight basis), and a content of other food waste (such as meat, pasta, etc.) of 13–16% on wet weight

2020/11/18/ · To achieve a sustainable and circular bio-economy, it is crucial to minimise food waste (FW, 88 M tonnes in EU annually) and use the unavoidable, inedible fraction as feedstock for the production of bio-chemicals [1,2].FW is rich in carbon, nutrients, and moisture, making it a favourable substrate for mixed microbial culture fermentation,

2023/10/22/ · Significant amounts of fermented food waste are generated worldwide, promoting an abundance of residual biomass that can be used as raw material to extract bioactive peptides, fermentable sugars, polyphenols, and valuable compounds for synthesizing bioproducts. Therefore, generating these high-value-added products
