2021/12/27/ · AD is a collection of processes by which microorganisms break down biodegradable material in the absence of oxygen. The process is used for industrial or domestic purposes to manage waste or to produce fuels. Much of the fermentation used industrially to produce food and drink products, as well as home fermentation, uses
2018/1/1/ · The disposal of large amounts of food waste has caused significant environmental pollution and financial costs globally. Compared with traditional disposal (i.e., landfilling, incineration, and composting), anaerobic digestion (AD) is a promising technology for food waste management, but has not yet been fully applied due
2023/5/6/ · Every year, about one-third of food is wasted through the food supply chain, generating many economic, environmental and social issues. Meanwhile, the increasing global energy demand and depletion of fossil fuels are driving international policies to promote the use of alternative energy sources.
2021/12/1/ · Owing to the rich amounts of salts and proteins in food waste, the food waste anaerobic digesate (FWD) generated from AD process contained a high concentration of phosphate (PO 4 3-), ammonium (NH 4 +), Na +, K +, and Cl − ions (Cheong et al., 2020).Thus, recycling the FWD into renewable and value-added products such as
2024/2/20/ · The laboratory's anaerobic fermenter, designed for food waste, boasts an effective volume of 1.8 L and operates on a semi-continuous feed system with a steady organic load of 60 g/L. Concurrently, both the hydraulic and sludge residence times are maintained at 18 days, with the initial pH externally regulated to 7.0.
