Olive-pomace oil is obtained by a chemical process from the kernels and residues of olive oil.

It has less nutritional power than other olive oils and is less expensive.

In its composition we find elaidic acid, a trans fat to be avoided (1).

Moreover, the percentage of saturated hydrocarbons found in olive-pomace oil is much higher than that found in centrifuged olive oil (2).

Due to the low nutritional value and contraindications of this oil, many studies have focused on the possibility of converting this oil into a positive resource. This study proposes an interesting biological method for transforming olive-pomace oil into fertilizer (3).
