Anaerobic digestion of the vegetable fraction of municipal refuses: mesophilic versus thermophilic conditions

Abstract

The phenomena limiting the anaerobic digestion of vegetable refuses are studied through batch tests carried out using anaerobic sludge previously selected under either mesophilic (37 °C) or thermophilic (55 °C) conditions

Recycled medical cotton industry waste as a source of biogas recovery

“…regarding the biogas production at mesophilic and thermophilic conditions. Converti et al (1999) found that passing from mesophilic to thermophilic conditions for the digestion of vegetable fraction of refuses is responsible for a slight deceleration of methane production but remarkably enhances both methanation yield and methane content of biogas. Vindis et al (2009) reported a decrease in solid retention time and increase in biogas production from anaerobic digestion of maize silage under thermophilic conditions.…”

Mesophilic batch anaerobic co-digestion of pulp and paper sludge and monosodium glutamate waste liquor for methane production in a bench-scale digester

“…The anaerobic digestion technology, properly implemented in an agro, municipal or industrial technical reality, can also be used to control malodorus emissions. The stabilized biomass can also be utilized as an excellent soil conditioner after appropriate treatment (Converti et al, 1999). The principle of a closed circuit is strengthened because the nitrogen hold strong by the system (MÖller et al, 2004).…”

Substituting energy crops with organic fraction of municipal solid waste for biogas production at farm level: A full-scale plant study

“…Anerobic digestion has many benefits-it produces biogas rich in methane, which can be used to produce electricity and hot water [14][15][16], and emits lesser greenhouse gases (e.g., CH 4 , N 2 O) and NH 3 [17]. In addition, during AD, the waste is converted to a valuable effluent that can be used in agriculture, because of its high nutrient as well as organic matter contents [14,18].…”
