Valorization of olive oil industry subproducts: ash and olive pomace fast pyrolysis

Environmental problems have encouraged investigation of renewable energies. The organic waste treating through fast pyrolysis seems to be a highly promising option for decreasing pollutants. Olive pomace, a major source of waste in countries with high production of olive oil (mainly Spain, Italy, an...

The organic waste treating through fast pyrolysis seems to be a highly promising option for decreasing pollutants. Olive pomace, a major source of waste in countries with high production of olive oil (mainly Spain, Italy, and Greece), is a clear target for valorisation. Dried olive pomace together with the ashes obtained during the drying process was blended to study the influence of the inorganic metals inherently present in the ashes (K, Na, Ca and Mg) for fast pyrolysis product distribution. The results determined that these metals increased yields of phenolic compounds until a maximum was reached, whereas carboxylic acid yield fell due to the action of metals. In addition, aromatic hydrocarbons and polyphenols were obtained for those samples with a large amount of ash. Moreover, the formation of organic acids, such as acetic acid, requires a smaller proportion of ash in the blend. Finally, it has been found that the ashes could be used as a catalyst for producing better quality bio-oil, thereby avoiding extra costs and thus valorizing the industrial treatment olive pomace.Los problemas medioambientales han fomentado la investigación de las energías renovables. El tratamiento de residuos orgánicos mediante pirólisis rápida parece ser una opción muy prometedora para la disminución de contaminantes. El orujo de aceituna, una fuente importante de residuos en países con alta producción de aceite de oliva (principalmente España, Italia y Grecia), es un claro objetivo de valorización. El orujo de oliva seco junto con las cenizas obtenidas durante el proceso de secado se mezclaron para estudiar la influencia de los metales inorgánicos inherentemente presentes en las cenizas (K, Na, Ca y Mg) para una distribución rápida del producto de pirólisis. Los resultados determinaron que estos metales incrementaron los rendimientos de compuestos fenólicos hasta alcanzar un máximo, mientras que el rendimiento de ácidos carboxílicos disminuyó por la acción de los metales. Además, se obtuvieron hidrocarburos aromáticos y polifenoles para aquellas muestras con gran cantidad de ceniza. Además, la formación de ácidos orgánicos, como el ácido acético, requiere una menor proporción de cenizas en la mezcla. Finalmente, se ha comprobado que las cenizas podrían utilizarse como catalizador para producir bioaceite de mejor calidad, evitando así costes extras y valorizando así el tratamiento industrial del orujo de oliva.Elsevier202220222021info:eu-repo/semantics/articleapplication/pdfapplication/pdfhttp://hdl.handle.net/10578/29862reponame:RUIdeRA.
