During the RP3 period (1/11/2023–31/12/2024), several notable achievements were accomplished.
Under Work Package 1 (WP1):
• D1.3 “Specific measures for algae production for youth employment”, includes proposals supporting algae-based youth employment; received on June 23, 2023.
• D1.4 “Market studies, business models and business plans (1st update)”, refines previous studies and models; submitted May 3, 2023.
• D1.5 “Price and cost modelling (incorporated into RES)”, addresses pricing and cost structures within algae-based renewable energy; received January 9, 2024.
• D1.7 “Market studies… (2nd update)”, continues earlier work; submitted April 30, 2024.
Under WP2:
• D2.5 “Chlorella cultivation parameters (1st update)”; received November 28, 2024.
• D2.6 (2nd update), further refines cultivation conditions; submitted April 30, 2025.
D7.4 “Logistics of the process”, outlines IDENER’s support to A4F and LEITAT in designing and modeling the algae supply chain, considering logistics, cost, and emissions. It defines long-, medium-, and short-term decision levels for sourcing industrial effluents, contributing to TEA in task 7.3; submitted June 3, 2024.
In WP8, D8.9 documented partners’ event participation. In WP9, annual KPI and impact deliverables were submitted on November 6, 2023, and October 3, 2024.
Besides submitted deliverables, REDWINE partners pursued their works for the full implementation of the demo unit. WP2 partners kept the research on the use of wine effluents. Their main constraints were the different compositions based on the different origin of the effluents. Different varieties provide different composition and that’s a problem for microalgae. Tests were performed on small reactors and solutions were assessed to make it possible for its use on the demo unit. WP3 was able to capture and store CO2 from wine fermentation not just in 2023 but also in 2024. To make it possible, it was necessary to train employees and make some adjustments on the system. At the end, it was possible to capture and store 2 tons of pure CO2. WP4 was involved in the construction of the demo unit. Problems with the permit were solved and the unit started its construction. It’s expected to be ready by the end of April. WP5 focused its work on obtaining extracts and making them available for WP6. WP6 was able to develop food solutions and kept the tests on vineyards for biostimulants and for the winemaking activities. The tests for cosmetics started after the expected date, but they are running and the first prototype is expected by September. WP7 worked on LCA activities and will provide full assessments at the end of the project. WP8 activities were related with communication and dissemination of the results and WP9, besides the project management, had work on the grant amendment.
No major constraints are expected through completion, though cosmetic testing delays remain a minor concern per task leader.
