If left untreated, the organic matter can pollute water sources and emit strong odors as it decomposes. The Composition of Pomace The composition of pomace is largely made up of the fibrous parts of the olive that do not release oil easily during the first extraction.
Environmental Impact of Olive Oil Pomace Waste and Sustainable Solutions
Extra virgin olive oil is cold-pressed and unrefined. The oil that remains trapped within the pomace must be extracted using solvents or other industrial methods, which leads to a different category of olive oil compared to the first cold-pressed extra virgin grade.
Economically, recovering oil from pomace increases overall yield and reduces waste, making production more efficient. The leftover solids are often used as biomass for energy production or as animal feed after proper treatment.
Environmental Impact of Olive Oil Pomace Waste Management
Pomace and the Quality Spectrum of Olive Oil In the hierarchy of olive oil grades, extra virgin and virgin olive oils come from the first mechanical pressing and are judged for flavor, aroma, and chemical purity. While this material still holds some oil, it is not suitable for direct consumption without additional refining.
