The Potential of Olive Mill Wastewater
What is Olive Mill Wastewater?
Olive mill wastewater is a byproduct generated during the olive oil extraction process. When olives are washed, crushed, and mixed with water to extract the oil, it results in the production of olive mill wastewater—a dark, bitter, and acidic liquid rich in natural compounds.
Why is it gaining attention?
Olive mill water is being explored for its unique profile of bioactive compounds, including polyphenols and antioxidants. Numerous articles and research papers have highlighted its potential in areas like cellular health, oxidative stress, and environmental sustainability. Below, we’ve listed some of the publications that explore why this byproduct is attracting scientific and wellness interest.
