dc.description.abstract | Steam-explosion is a promising technology for recovering phenolic compounds from
olive mill solid waste (OMSW) due to its high impact on the structure of the fibre. Moreover, the
recovery of the phenols, which are well-known microbial inhibitors, could improve the subsequent
biomethanization of the dephenolized OMSW to produce energy. However, there is a considerable lack
of knowledge about how the remaining phenolic compounds could affect a long-term biomethanization
process of steam-exploded OMSW. This work evaluated a semi-continuous mesophilic anaerobic
digestion of dephenolized steam-exploited OMSW during a long operational period (275 days),
assessing different organic loading rates (OLRs). The process was stable at an OLR of 1 gVS/(L·d),
with a specific production rate of 163 ± 28 mL CH4/(gVS·d). However, the increment of the OLR up to
2 gVS/(L·d) resulted in total exhaust of the methane production. The increment in the propionic acid
concentration up to 1486 mg/L could be the main responsible factor for the inhibition. Regardless of the
OLR, the concentration of phenolic compounds was always lower than the inhibition limits. Therefore,
steam-exploited OMSW could be a suitable substrate for anaerobic digestion at a suitable OLR. | es |
