Amurca
Amurca is the Latin name for the bitter-tasting, dark-colored, watery sediment that settles out of unfiltered olive oil over time. It has been known in English as "olive oil lees"[1] and recently as "olive mill waste water (OMWW)".[2] Historically, amurca was used for numerous purposes, as first described by Cato the Elder in De Agri Cultura, and later by Pliny the Elder.[3] Cato mentions its uses as a building material (128), pesticide (91, 92, 96, 98), herbicide (91, 129), dietary supplement for oxen (103) and trees (36, 93), food preservative (99, 101), as a maintenance product for leather (97), bronze vessel (98), and vases (100), and as a treatment for firewood in order to avoid smoke (130).[4]
