Fecha de publicación: | nov-2017 | Editor: | Elsevier | Citación: | Bioresource Technology 243: 169-178 (2017) | Resumen: | A promising source of high added value compounds is the Olive Mill Solid Waste (OMSW). The aim of this research was to evaluate the viability of a biorefinery approach to valorize OMSW through the combination of steam explosion, phenols extraction, and anaerobic digestion. Steam explosion treatment increased the total phenol content in the steam exploited OMSW, which was twice than that the total phenol content in raw OMSW, although some undesirable compounds were also formed. Phenol extraction allowed the recovery of 2098 mg hydroxytyrosol per kg of OMSW. Anaerobic digestion allowed the partial stabilization of the different substrates, although it was not improved by the steam explosion treatment. The economic suitability of the proposed biorefinery approach is favorable up to a phenol extract price 90.7% lower than the referenced actual price of 520 €/kg. | Descripción: | 32 Páginas; 6 Tablas; 4 Figuras | Versión del editor: | http://dx.doi.org/10.1016/j.biortech.2017.06.093 | URI: | http://hdl.handle.net/10261/158373 | ISSN: | 0960-8524 | E-ISSN: | 1873-2976 |
