Blue Mallee is the only major oil producing species which can be mechanically harvested. As the species is confined to Australia, it enables Bosisto’s Eucalyptus Oil to compete against competitors with low labour costs. The Blue Mallee is cut by a harvester a few centimetres from the ground. The cut material is thrown up a chute directly into a mobile still which is towed behind. Once the mobile still is filled with about three tonnes of leaf, it is uncoupled and another still attached. When two or three stills are filled a second tractor tows the stills to the distillery.
