Only olives picked directly from the olive trees are used in the extraction of olive oil. The mechanical and manual harvesting allows a careful selection, and all the operations are minutely followed, from the olive grove to the expedition of the final product. It is all this requirement that gives rise to high quality olive oils.
With the growing concern of respecting the environment, Lagar Cartuxa [Cartuxa Olive Oil Mill] has a washing water treatment unit which allows its reuse in the olive grove irrigation.
