Improved biogas yield from organic fraction of municipal solid waste as preliminary step for fuel cell technology and hydrogen generation

Source separation, transportation, pretreatment, and valorization of municipal solid waste: a critical review

“…to produce value-added products (Sindhu et al, 2019 ). However, due to the inherent recalcitrance of the lignocellulosic biomass and the heterogeneity of OFMSW (Karthikeyan et al, 2017 ; Veluchamy & Kalamdhad, 2017 ), hydrolysis limits the biotransformation efficiency (Bala et al, 2019 ). Substrate pretreatment is an effective strategy to improve the biodegradability of OFMSW before bioconversion (Kavitha et al, 2017 ), which can improve the water solubility of complex organic matter.…”

Recent Progress and Trends in the Development of Microbial Biofuels from Solid Waste—A Review

“…The organic fraction of municipal solid waste (OFMSW) consists of a complex mixture of polysaccharides, proteins, and fats that require pretreatment due to the presence of lignocellulosic biomass in OFMSW [113]. Thus, pretreatment prior to anaerobic digestion is necessary to (A) transform the large molecules into simpler molecules, (B) offer a larger surface area for degradation, and (C) promote the accessibility of food for microorganisms by increasing the substrate porosity [114]. Several methods of pre-treatment that have been studied are classified as physical pretreatment [115], chemical pretreatment [116], thermal pretreatment [117], biological pretreatment [118], and combinational pretreatment [119].…”

Energy generation from anaerobic co-digestion of food waste, cow dung and piggery dung

“…Anaerobic digestion leads to the production of biogas mixtures comprising mainly between 50 and 70% methane, 30 to 50% carbon dioxide and other gases including H 2 , NH 3 and H 2 S contingent upon the nature of the organic matter/feedstock being employed (Saha et al, 2016). Many researches have demonstrated the use of different feedstock in AD which includes agricultural wastes and plant residues, food and other domestic wastes, solid and liquid wastes from municipalities and industries for the production of biogas (Dahunsi et al, 2016a,b, Dahunsi et al, 2017aOloko-Oba et al, 2018;Bala et al, 2019;Slorach et al, 2019).…”
