Novel Sophorolipid Biosurfactant

Valorization of orange peels for biosurfactants.

Project VALORBIOSURF is a development project to combine PeelPioneers’ sugar-rich residual streams from their orange peels process with Holiferm’s fermentation technology to develop new routes for production of sophorolipid biosurfactant. This highly sustainable biosurfactant is 100% biobased, non-food competitive and circular.

  • PeelPioneers.

    PeelPioneers offers a 100% circular solution for orange peels that in most countries end up getting destroyed in an incinerator. They extract orange oil and other much-wanted raw materials that food manufacturers use in products such as beer, lemonade, muffins and chocolate. The raw materials that PeelPioneers derives from orange peels are also sold to manufacturers of non-food products such as detergents and cosmetics. PeelPioneers is the largest producer of raw materials from citrus peels in Northwest Europe.

  • Holiferm.

    Holiferm is a purpose-led company that aims to accelerate the transition to a circular economy by developing and supplying sustainable, non-fossil-based, fermentation-derived ingredients for industrial and consumer products. Holiferm’s integrated gravity separation fermentation process provides a low-cost route to a range of biosurfactants and other lipid molecules, delivering high productivity fermentation processes for the manufacture of green, biobased and biodegradable molecules.
