Effect of microwave irradiation on anaerobic degradability of model kitchen waste

Optimization and microbial community analysis of anaerobic co-digestion of food waste and sewage sludge based on microwave pretreatment

“…Meanwhile, the effects of microwave pretreatment of FW (MW-FW) on AD were investigated, while contrary results existed. Marin et al (2010) indicated that anaerobic biodegradability could be improved by 9% after MW of model FW. In contrary, Shahriari et al (2013) recommended that digester staging without MW be employed to maximize methane production in comparison with MW-FW.…”

Influence of Microwave Pre-Treatment on the Digestion and Higienisation of Waste Activated Sludge/Wpływ Dezintegracji Mikrofalowej Na Proces Fermentacji Oraz Higienizacji Nadmiernych Osadów Ściekowych

“…Under conditions of high temperature, denaturation, aggregation and precipitation of dissolved protein occur, which are believed to be associated with changes in their degrees of hydration and solubility. Decrease in biopolymers content at temperature of ~80°C is frequently observed [6,19,20].…”

Organic Fraction of Municipal Solid Waste: Overview of Treatment Methodologies to Enhance Anaerobic Biodegradability

“…A wide range of temperatures (50-250 • C) to upgrade the AD of diverse organic fraction of solid wastes have been worked-out by various groups of reseachers. The fundamental impact of thermal treatment is the disruption of cell wall and aiding into solubilization of organic material (Marin et al, 2010;Protot et al, 2011). COD solubilization and temperature have direct impact on biogas yield.…”

“…Mottet et al (2009) studied diverse thermal treatment techniques and reported no considerable distinction amongst steam and electric heating, while microwave heating has been observed to solubilize more biopolymers. The higher rate of solubilization with microwave treatment was due to the phenomenon of polarization of macromolecules present in the feedstock (Toreci et al, 2009;Marin et al, 2010). Thermal treatment at significantly high temperatures (>170 • C) may result into formation of bonds and agglomeration of the particles (Bougrier et al, 2006).…”

“…The impact of microwave treatment on the anaerobic biodegradability of kitchen waste was contemplated by Marin et al (2010). In this study, FW was treated at 175 • C to solubilise the sugars and proteins present.…”
