Industries using olive oil pomace are growing fast
Olive oil pomace is widely used today across multiple industries - including food manufacturing, energy (biofuel and cogeneration), cosmetics and pharmaceuticals, agriculture (fertilizers and soil amendments), animal feed, and materials (bioplastics and active packaging) - and industrial adoption accelerated in the 2018-2025 period as extraction and upcycling technologies matured.
What olive oil pomace is
Olive oil pomace is the solid and semi-solid residue (skins, pulp, stones and process water) left after virgin olive oil extraction, and it contains residual oils, phenolic antioxidants, fibers and minerals that make it a feedstock for diverse value chains.
Top industries using pomace
Food and foodservice manufacturers use refined pomace-derived oils and phenolic extracts for high-heat frying, margarine and processed foods, and some bakeries and pasta producers incorporate pomace flour for fiber and antioxidant enrichment.
- Deep-frying and industrial frying oils (pomace olive oil) used by foodservice companies and fast-food chains.
- Functional food ingredients: phenolic extracts added to spreads, meat formulations and shelf-life extension coatings.
- Ingredient supply to private-label food manufacturers seeking lower-cost olive-derived oils.
Energy and cogeneration operators convert pomace and olive stones to biomass fuel or use crude pomace for cogeneration plants that supply heat and power to mills and local grids.
- Combustion of dried pomace and stones in boilers for on-site heat.
- Pelletisation and sale of biomass to district heating or industrial boilers.
- Biogas and pyrolysis pilot projects that convert wet pomace into syngas or bio-oil.
Cosmetics and pharmaceuticals extract hydroxytyrosol, squalene and phenolic fractions from pomace for anti-inflammatory, antioxidant and moisturizing formulations.
Agriculture and fertilizers use composted pomace and mineral-rich process residues as organic fertilizers, soil conditioners and slow-release nutrient sources that improve soil structure and water retention.
Animal feed producers incorporate treated pomace fractions (dried, partially defatted) into ruminant and monogastric diets to add fiber, unsaturated fatty acids, and antioxidants - typically after palatability and digestibility optimization.
Materials and packaging companies use pomace-derived lignocellulosic fibers and polyphenol extracts to produce biodegradable composites, active (antioxidant) food packaging and natural dyes for textiles and paper products.
Representative data snapshot
Illustrative market and processing figures below summarize adoption, typical yields and commercial values observed by industry analysts and manufacturers between 2019 and 2025.
| Industry | Typical pomace use | Estimated yield from 1,000 t pomace | Commercial value range (EUR) |
|---|---|---|---|
| Food / frying oil | Refined pomace olive oil | ~2,000-4,000 L pomace oil | €20,000-€50,000 |
| Energy (biomass) | Combustion pellets, boiler fuel | ~600-800 MWh equivalent | €10,000-€30,000 |
| Cosmetics / pharma | Phenolic extracts, squalene | 5-50 kg high-value extract | €5,000-€120,000 |
| Agriculture | Compost, soil conditioner | ~600 t compost | €6,000-€18,000 |
| Materials / packaging | Fiber composites, active films | 200-1,000 t fiber feedstock | €10,000-€70,000 |
Historical context and timeline
Industrial interest in olive pomace intensified after the early 2000s when environmental regulation and biomass markets made waste valorization economically attractive; by 2015 researchers began publishing scalable extraction routes for phenolics and squalene that created new downstream demand.
Key milestones include the 2012-2016 wave of EU research projects on olive mill wastes, a commercial scale-up of pomace oil refining in Spain and Italy around 2017-2020, and wider adoption of circular-processing lines (evaporation, decanter separation) in 2021-2024 that increased extract recovery rates by double-digit percentages.
Technologies enabling new uses
Decanter separation and multi-stage evaporation allow mills to extract higher-value pomace oils and concentrate antioxidants for sale to food and cosmetics firms.
"Advanced separation has turned a disposal problem into a revenue stream," an industry technical lead told trade press during 2023 rollout of integrated pomace lines.
Solvent-free and green-extraction methods (membrane filtration, supercritical CO2 pilots) reduce environmental impact and produce cleaner extracts suitable for nutraceutical markets.
Economic and sustainability drivers
Regulatory pressure in Mediterranean basin countries has pushed mills to reduce wastewater and solid-waste disposal costs, making valorization financially attractive since 2018.
Price dynamics for refined pomace oil typically sit at ~20-40% of extra virgin olive oil pricing, creating a market niche for cost-sensitive food manufacturers and large-scale fryers.
Barriers and challenges
Sensory and processing challenges: direct addition of crude pomace into foods can alter texture and taste, which restricts direct food use without fractionation or refining.
Regulatory and quality constraints: some jurisdictions classify pomace oil and extracts differently for food vs. non-food use, requiring separate refining and certification to sell into edible markets.
Practical examples and case studies
Spanish and Italian mills that implemented decanter + evaporation lines reported converting hundreds of thousands of tonnes of wet pomace into saleable oil and antioxidant concentrates between 2019-2024, creating new revenue streams while cutting disposal costs.
Packaging startups using pomace fiber reported prototype trays and films with improved antioxidant activity suitable for short-shelf-life produce packaging in 2022-2024 pilot runs.
Policy and market outlook
Market forecasts from regional analysts in 2024-2025 estimated 6-10% annual growth in commercial pomace-derived ingredient demand across EU foodservice, cosmetics and bioenergy segments through 2030, driven by circular-economy mandates and rising extract recovery rates.
Trade flows remain concentrated in Mediterranean producer countries (Spain, Italy, Greece, Turkey) but technology licensing and mobile processing units are increasing export of processed extracts and pellets worldwide.
Implementation checklist for companies
Entry requirements for a company planning to use pomace: assess feedstock quality, choose extraction or energy route, secure permits for handling and refining, and validate product quality via lab tests.
- Sample and analyze pomace streams for moisture, oil content and phenolics.
- Select technology: mechanical drying + combustion, decanter + evaporation, or solvent/CO2 extraction for high-value compounds.
- Model economics: yield per tonne, CAPEX for line, expected product prices and by-product values.
- Plan regulatory compliance: food-grade refining certificates if selling edible oil or extracts.
Quotes and industry voices
Industry analysts observed in 2023-2024 that "value recovery from pomace will define the next decade of olive-sector competitiveness" as quoted in trade briefings and technical conferences.
"Turning pomace into products is no longer optional - it's a revenue imperative," said a Mediterranean mill director speaking at a 2024 sector forum.
Useful metrics to track
Key performance indicators for organizations scaling pomace use include oil recovery rate (L/t pomace), phenolic yield (mg/kg), calorific value (MJ/kg), and net revenue per tonne after processing.
| KPI | Target range | Why it matters |
|---|---|---|
| Oil recovery (L/t) | 2-6 L/t | Directly determines edible oil revenue potential. |
| Phenolics (mg/kg) | 200-2,500 mg/kg | Drives value for nutraceutical and cosmetic extracts. |
| Calorific value (MJ/kg) | 12-20 MJ/kg | Determines suitability for biomass energy conversion. |
Actionable next steps for readers
Producers should pilot small-scale fractionation to test extract markets before investing in full-scale lines, and track regulatory requirements for food versus non-food labeling.
Buyers (food manufacturers, cosmetic firms) should request certificate-of-analysis and source-chain traceability for pomace-derived ingredients and consider co-investment with mills to secure supply.
