“…The reason is that at the high concentration of feedstock, the rate of hydrolysis/acidogenesis is higher than that of methanogenesis. Hence, short chain fatty acids (SCFA) accumulated from hydrolysis/acidogenesis eventually lead to an irreversible acidification and thus limit methanogenesis [118]. On the other hand, for the CLM feedstock the X_c is too low and hence there is insufficient digestible matter to generate biogas.…”

“…Anaerobic digestion yields depend on several factors [55,56], including temperature [57][58][59][60], organic loading rate [61][62][63][64] and substrate to inoculum ratio [65][66][67]. Under similar operating conditions, substrate characteristics play a key role in defining the amount of biogas that can be recovered by anaerobic digestion, as the theoretical gas yield varies with substrate composition in terms of carbohydrates, proteins and fats, as given in Table 1.…”

Abstract:In the last decades the increasing energy requirements along with the need to face the consequences of climate change have driven the search for renewable energy sources, in order to replace as much as possible the use of fossil fuels. In this context biomass has generated great interest as it can be converted into energy via several routes, including fermentation and anaerobic digestion. The former is the most common option to produce ethanol, which has been recognized as one of the leading candidates to substitute a large fraction of the liquid fuels produced from oil. As the economic competitiveness of bioethanol fermentation processes has to be enhanced in order to promote its wider implementation, the most recent trends are directed towards the use of fermentation by-products within anaerobic digestion. The integration of both fermentation and anaerobic digestion, in a biorefinery concept, would allow the production of ethanol along with that of biogas, which can be used to produce heat and electricity, thus improving the overall energy balance. This work aims at reviewing the main studies on the combination of both bioethanol and biogas production processes, in order to highlight the strength and weakness of the integrated treatment for industrial application.

“…According to increased OFMSW content, Gou et al [4] varied the volumetric organic load of the binary mixture with sewage sludge, from 1 to 8 g VTS/L.d., and in a continuous process co-digestion they observed a pH drop from 7.0 to 4.9 and 43% of VTS removal.…”

“…The combination of different organic substrates increases the diversity of carbon molecules structure, which improves anaerobic bacteria metabolism, destruction of volatile solids, and generation of biogas and methane [1][2][3]. In this context, OFMSW has been largely studied as a potential residue for co-digestion of sewage sludge [4,5].…”

“…According to Astals et al [30], from the co-digestion of a binary mixture of swine manure and 4% (v/v) glycerol, 62% removal of COD was obtained, which resulted in 64% increase of biogas production and 235 mL CH 4 /g VTS applied of specific methane production. Martin et al [31] reported a specific methane production of 385 mL CH 4 /g VTS applied derived from the co-digestion of orange peel and glycerol.…”

This paper presents bench scale experiments related to anaerobic co-digestion of aerobic sewage sludge from a pilot WWTP (waste water treatment plants), raw glycerol from a biodiesel industry and food waste. Assays were conducted in 100 mL non-stirring penicillin vessels, at 30 °C and planned according to three optimization phases: (1) binary mixture of sewage sludge and FW (food waste); (2) binary mixture of sewage sludge and glycerol; and (3) ternary mixture of sewage sludge, FW, and glycerol. In the first and second phases, the highest SMP (specific methane production) was achieved by 10% (v/v) FW and 0.5% (v/v) glycerol mixtures. The optimization of the ternary mixture during the third phase was reached by the combination of 10% (v/v) FW and 0.4% (v/v) glycerol. Despite the low SMP value, the addition of glycerol and FW contributed to doubling the SMP value of the sludge sample control.
