The consortium of REDWine, a project coordinated by Leitat and formed by 12 partners, gathered on 12–13 March 2024 in Hengelo, the Netherlands, to evaluate current progress and define priorities for the final stages of the project.
The meeting focused on key advances to develop a circular business model for the wine industry. Partners shared updates on Chlorella cultivation using winery wastewater, including progress on medium optimization, pilot-scale production, and biomass composition. Technical sessions covered developments in off-gas storage systems, energy-efficient harvesting, and the demo-scale cultivation of microalgae. Further discussions addressed the recovery of bioactive compounds from Chlorella for high-value applications in food, cosmetics, and agriculture.
The second day of the meeting concentrated on sustainability modeling, logistics strategies, and the validation of Chlorella-based product prototypes, as well as refining communication strategies to reach stakeholders. The event concluded with project coordination discussions, aligning the consortium’s final steps toward reducing GHG emissions and enhancing resource valorisation in the wine sector.
During the meeting, Leitat showcased its work on the recovery of bioactive compounds from Chlorella biomass, including pilot-scale tests and ingredient prototype development. Leitat also reported progress on the separation of volatile organic compounds (VOCs) from the culture medium and outlined next steps to optimize biomass processing and VOC recovery in line with the project’s goals.
Beyond the working sessions, the consortium visited the Grolsch brewery and the Pervatech facilities, gaining insights into other circular practices.
