Morocco Olive Pomace Oil Extraction Process: The Synergy of Solvent Extraction, Drying, and Biomass Boilers
Date:May 8th, 2026
How Integrated Processing Technology Maximizes Value from Olive Pomace
Morocco is one of the largest olive-producing countries in North Africa, generating millions of tons of olives and olive oil products every year. Alongside this thriving industry comes a substantial amount of olive pomace—the solid residue remaining after olive oil production.
Traditionally viewed as a low-value by-product, olive pomace is now recognized as an important industrial raw material. Through modern solvent extraction and refining technologies, processors can recover residual oil, reduce waste, and create additional revenue streams.
Today, many Moroccan olive processors are investing in integrated olive pomace processing plants that combine drying, solvent extraction, refining, and biomass energy systems. This approach not only improves oil recovery but also transforms waste into valuable energy resources.
Understanding Olive Pomace Composition
Fresh olive pomace typically contains:
Residual olive oil
Olive pulp
Olive skins
Crushed olive pits
Organic solids
High moisture content
Depending on the olive oil production method, fresh pomace generally contains significant moisture and residual oil that can still be economically recovered.
A typical processing scenario shows that:
100 tons of fresh olive pomace can generate approximately:
5 tons of crude olive pomace oil
60 tons of de-oiled pomace residue
35 tons of evaporated moisture during drying
These figures may vary depending on raw material quality, oil content, and process efficiency, but they clearly demonstrate the economic potential of olive pomace processing.
Step 1: Drying – The Foundation of Efficient Oil Recovery
Fresh olive pomace usually contains high levels of moisture, which creates several challenges:
Reduced extraction efficiency
Increased solvent consumption
Higher transportation costs
Difficult storage conditions
Increased risk of spoilage
Therefore, drying is one of the most critical stages in the entire processing chain.
Why Drying Matters
Reducing moisture content before extraction offers several benefits:
Improves solvent penetration
Enhances oil recovery rates
Reduces solvent losses
Improves extraction stability
Lowers transportation and storage costs
Industry experience shows that properly dried olive pomace can reduce transportation costs by approximately 30% due to lower material weight and improved handling characteristics.
Dryer Selection Considerations
When selecting an olive pomace dryer, processors should consider:
Daily processing capacity
Initial moisture content
Final moisture requirements
Energy consumption
Heat source availability
Dingsheng Machine Olive Pomace Dryers
Our drying systems feature:
Continuous operation design
High thermal efficiency
Stable moisture control
Low energy consumption
Large-capacity processing capability
These systems are designed specifically for the characteristics of olive pomace and can be integrated directly with extraction plants.
Step 2: Solvent Extraction – Recovering Maximum Oil Value
After drying, olive pomace enters the extraction section.
Mechanical pressing is generally unsuitable for recovering the low levels of residual oil remaining in pomace. Therefore, modern plants utilize solvent extraction technology, typically based on hexane.
How Hexane Extraction Works
The extraction process involves:
1. Dried pomace enters the extractor.
2. Hexane solvent dissolves the residual oil.
3. The oil-solvent mixture is separated.
4. Solvent is recovered through evaporation and condensation.
5. Crude olive pomace oil is collected for refining.
This technology offers the highest oil recovery efficiency available for industrial olive pomace processing.
Advantages of Solvent Extraction
Higher oil yield
Lower residual oil content in meal
Continuous operation
Improved profitability
Reduced raw material waste
Key Extractor Selection Factors

Step 3: Biomass Boilers – Turning Waste into Energy
One of the most valuable advantages of olive pomace processing is the utilization of de-oiled pomace residue.
After extraction, approximately 60 tons of solid residue may remain from every 100 tons of fresh pomace processed.
Rather than treating this material as waste, modern plants utilize it as biomass fuel.
Why Biomass Boilers Matter
Biomass boilers allow processors to:
Reduce fuel costs
Lower dependence on fossil fuels
Improve sustainability
Create closed-loop energy systems
Reduce environmental impact
The de-oiled pomace has significant calorific value and can provide a substantial portion of the thermal energy required for drying and refining operations.
Integrated Energy Recovery
In a modern olive pomace processing facility:
Biomass residue fuels the boiler.
The boiler generates steam and hot air.
Steam supports refining operations.
Hot air supplies drying systems.
This creates a highly efficient synergy between drying, extraction, and energy production.
Dingsheng Machine Biomass Boiler Solutions
Our biomass systems offer:
High combustion efficiency
Stable steam generation
Automatic feeding systems
Low emission design

Step 4: Olive Pomace Oil Refining
The crude oil produced during extraction contains:
Free fatty acids
Pigments
Waxes
Odors
Trace impurities
To meet commercial requirements, the oil undergoes refining.
Typical refining stages include:
Degumming
Neutralization
Bleaching
Deodorization
Dewaxing
The resulting refined olive pomace oil can be sold to domestic and international markets, significantly increasing product value.
Our engineering team helps customers transform olive pomace from a processing challenge into a profitable business opportunity.
