More competitiveness for the Olive Oil Sector


Research Engineers to revalorise olive oil residues by extracting polyphenolic compounds


Chemical and electronic engineers from Barcelona, Bordeaux and Vienna work together within a joint research project aiming at revalorising the waste of pomace oil producers. After processing olive pomace, around 2 - 8 g polyphenols/kg is lost representing by 80% of the total content. These polyphenols are valuable for emerging markets such as cosmetics, functional foods, supplements, preservatives in industrial production and animal health. The EU polyphenols market was estimated at €77.88M in 2003, and at € 120M (2250 tonnes) in 2011. Recent studies have forecasted a market of € 290M in 2016. Laboratoire Phenobio, Repotec, Hakki Usta, Effitech and Mora Industrial invested in the Phenolive research in order to give a response to a growing market. Besides, Phenolive is to offer a solution to reduce olive pomace waste management and transportation needs, with the consequent reduction in costs.Considering that almost 8M tonnes of olive pomace are generated every year in Europe and the high added - value that the technology would imply for the European economy, the European Union granted the initiative by up to 73%. The five companies estimated their research cost as €1.5M and a working period of 30 months.
