PAIDI groups in the Unit:

This unit works on the study of the physical, chemical and sensory composition of olive oils, as well as on the characterization, use and exploitation of by-products from olive grove, oil mills, extractors and refineries. To achieve this goal, olive stones and olive grove pruning are analysed to produce biofuels from these products derived from olive groves.
