It is a fact and common knowledge that the Mediterranean Sea is a rich region and adapted to the growth of several vegetal species, as well as the production of a lot of products deriving from those. Among the typical activities in this region, there is the olive trees cultivation, from which it is possible to obtain numerous olive oil and olive qualities. The Mediterranean zone is responsible for the production of about 98% of the olive oil world-wide produced, which counts 900 million of olive trees occupying 10 million of hectares. However, the manipulation of 100 kg of olives leads to the production of 40 kg of wastes (woody parts, leaves and olive pomace), which is potentially valorisable and usable as energetic or material source.
