The present thesis focused on the technologies for the utilization of two-phase olive mill waste. The two-phase mill waste treatment method is the most ecological method, thanks to the production of a small amount of liquid waste, as well as biochemically required oxygen, compared to other methods. Through a literature review, the most important technologies for the utilization of olive mill waste were studied and analyzed, with an emphasis on phenolic compounds. Membrane filtration extraction aimed at the fractionation of phenolic compounds emerged as the most efficient method. Then, followed the sustainability study, with the aim of calculating sustainability indicators, related to the environmental footprint of the scenarios studied. In particular, the "Climate Change" indicator yielded satisfactory results in each scenario, with the pellet manufacturing method performing better, compared to thermochemical methods and composting. Then, regarding the performance indicator, the composting method presented a better value of the ratio of product per raw material. As for the energy consumption, less energy requirements were observed in biological conversion methods, followed by the production of briquettes and pellets.
