Title: Novel olive oil extraction plant with environmental benefits

Water that is lost as vapor during the drying process in traditional olive oil extraction plants is recovered with this project and one third of the current drying costs are expended. Several successful plants have been built as demonstration units that incorporate a new three-step process: quick solid products separation, thermal liquid products concentration, and treatment of the remaining water. The recovered water is used for irrigation and the concentrated liquid and solid compounds as fertilizer. An important pollution problem in Mediterranean countries is solved with this project.
