Olive biophenol integral extraction at a two-phase olive mill

The biophenol integral extraction protocol from vegetation water developed in the early 2000s for the three-phase olive mill was adapted to a large two-phase mill operating in Sicily during the 2016/2017 season. The new set-up allows extensive recovery of olive phenolics, affording after nine months natural extracts with hydroxytyrosol concentration exceeding 1500 ppm. Previous toxic waste is transformed into a source of additional revenues for the milling company, and of valued bioproducts for the bioeconomy partner, eliminating altogether a source of potential pollution.
