Should industrial research prioritize converting agricultural waste into new commercial products?
In 2024, BKEA Ltd and Middle East Technical University launched the SustainOlive research project to analyze olive pomace. This 24-month initiative aims to extract beneficial compounds typically discarded during the olive oil manufacturing process.
Why it matters
Only a small fraction of healthful phenolic compounds transfers into olive oil during standard pressing, meaning significant chemical potential remains in the waste. Recovering these compounds could improve the sustainability and nutritional profile of food industry byproducts.
The SustainOlive project involves a 24-month investigation into the recovery of lipids, proteins, and phenolic compounds from olive pomace. Findings regarding the bioavailability of these extracted peptides are currently pending further testing under simulated digestive conditions.
The players
BKEA Ltd
A research entity based in Malta focused on chemical innovation and sustainable extraction technologies.
Middle East Technical University
A public research university in Türkiye conducting scientific studies on agricultural waste processing.
The details
The research team employs closed-loop extraction systems to capture oil-soluble compounds from the pomace. Additionally, they utilize Deep Eutectic Solvents and ultrasound-assisted extraction to specifically recover polar bioactive fractions. The project further explores how microorganisms might convert the remaining lignocellulosic plant material into value-added products.
Timeline
The SustainOlive research project launched in 2024.
The research initiative is scheduled for a 24-month duration.
Health Landscape
This project aligns with the MCST-TÜBİTAK Joint Call for Research and Innovation to standardize sustainable agricultural practices. It reflects a broader shift toward circular food systems where industrial waste is treated as a secondary source of bioactive human nutrients.
While this research focuses on industrial extraction, it underscores the importance of bioactive compounds like phenolics in your diet. Discussing the role of plant-derived antioxidants with a registered dietitian or your doctor can help you understand how to incorporate such nutrients safely.
The takeaway
The SustainOlive project highlights that olive oil waste contains significant, untapped nutritional potential including proteins and antioxidants. As these recovery methods evolve, look for future food products that utilize upcycled, nutrient-dense ingredients in your balanced diet.
