AQUACOMBINE: Sustainable Extraction of Compounds from Halophytes

The AQUACOMBINE project (2019–2023) developed sustainable, green extraction methods—such as subcritical water and supercritical CO2—to isolate proteins, lipids, and bioactive compounds like hydrocinnamic acids and flavonoids from halophytes, particularly Salicornia ramosissima. Led by Stéphane Kohnen (2019–2022) and later by Job Tchoumtchoua at CELABOR in Belgium, the project identified over 100 phenolic compounds, exceeding initial expectations. Based in the Petit-Rechain industrial park near Verviers, CELABOR’s Food Technologies – Extraction department utilized its ExPROOF zone and pilot-scale equipment to advance eco-friendly processes. The research supports the circular economy by valorising salt-affected land biomass for applications in food, feed, and cosmetics, with potential to guide future European Commission and industrial investments in the sustainable bioeconomy.
