During six months of experimentation, a plug-flow system without recirculation was employed to study the volatile fatty acids (VFA) production by means of anaerobic fermentation of urban organic wastes. Results showed an important VFA production at mesophilic range of temperature (37°C). Particulary, VFA concentration in the outlet sludge went from 11.8 g/L at 2 days of retention time up to 23....

Anaerobic co-digestion has been widely investigated, but there is limited analysis of interaction between substrates. The objective of this work was to assess the role of carbohydrates, protein and lipids in co-digestion behaviour separately, and together. Two sets of batch tests were done, each set consisting of the mono-digestion of three substrates, and the co-digestion of seven mixtures. Th...

Abstract Lignocellulosic biomass wastes are abundant resources that usually valorized for methane-rich biogas via anaerobic digestion. Conversion of lignocellulose into volatile fatty acids (VFA) rather than is attracting attention due to the higher value-added products come with VFA utilization. This review consolidated latest studies associated characteristics lignocellulosic biomass, effects...
