REDWine successfully tested the system under real operation conditions in its demonstration site in Palmela, Portugal, where it recovered two tonnes of CO<sub>2<\/sub> per year. The recovered CO<sub>2<\/sub> was reused as a growth input for microalgae cultivation. Winery wastewater served as the liquid medium, enabling the\u00a0<a href=\"https:\/\/link.springer.com\/article\/10.1007\/s10811-024-03422-8\" target=\"_blank\" rel=\"noreferrer noopener\">cultivation of <em>Chlorella vulgaris<\/em><\/a>, a versatile microalgae species, in a range of photobioreactor systems developed by the project, including flat-panel, tubular and AI-controlled designs.<\/p>\n\n\n\n<p>REDWine estimates that its system can achieve more than a 30% reduction in the carbon footprint across the wine value chain. Microalgae biomass produced through this process can be processed into proteins, lipids, pigments and bioactive compounds, finding applications in agriculture, cosmetics, food and in winemaking itself, where algae-based ingredients can replace sulphites as preservatives.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Scalable business models for European wine regions<\/h3>\n\n\n\n<p>The project developed and tested three complementary business models. In the winery-integrated model, a single producer installs the full system on site. In the centralised biorefinery model, individual wineries produce biomass, while the processing and extraction of valuable compounds take place in a shared regional facility, reducing investment and operational complexity for wineries. The third model consists of a cooperative approach, where a centralised shared facility, or bio-hub, performs both algae cultivation and biomass processing. This set-up offers greater scalability and efficiency, and it includes smaller wineries in the system, without requiring major infrastructure investments. <\/p>\n\n\n\n<blockquote class=\"wp-block-quote is-layout-flow wp-block-quote-is-layout-flow\">\n<p>\u201cThe REDWine project proposes a staged commercialisation pathway,\u201d says <strong>Cach\u00e3o<\/strong>. \u201cIt recommends starting with carbon capture solutions at wineries and gradually expanding toward regional cooperation and centralised processing hubs.\u201d <\/p>\n<\/blockquote>\n\n\n\n<p>By adopting the system, wineries could generate new income from the sale of microalgae biomass, refined bioactive ingredients, captured CO<sub>2<\/sub> and premium sustainable wines. The project estimates a total addressable market of EUR 3.55 billion for microalgae-derived ingredients. Beyond revenues, the cooperative bio-hub model would require specialised skills across algae production, biorefinery operations and logistics, creating new employment opportunities in rural wine-producing regions. <\/p>\n\n\n\n<blockquote class=\"wp-block-quote is-layout-flow wp-block-quote-is-layout-flow\">\n<p>The model shows strong potential for replication, \u201cparticularly in southern Europe \u2013 Spain, France, Italy and Portugal \u2013 where most vineyards, sunlight availability and sustainability initiatives converge,\u201d notes <strong>Cach\u00e3o.<\/strong> <\/p>\n<\/blockquote>\n\n\n\n<p>These regions also have cooperative business structures that can serve as a framework for shared bio-hubs and biorefineries. <\/p>\n\n\n\n<blockquote class=\"wp-block-quote is-layout-flow wp-block-quote-is-layout-flow\">\n<p><strong>He<\/strong> concludes: \u201cAs carbon pricing, sustainability certification and consumer demands for eco-wines grow, REDWine can be scaled across European wine regions, transitioning from local pilots to a continent-wide model that enhances environmental performance, economic resilience and cross-sector innovation in the bio-based economy.\u201d<\/p>\n<\/blockquote>\n","protected":false},"excerpt":{"rendered":"<p>The European wine industry is under pressure to cut emissions, reduce additives and operate more sustainably, while remaining economically competitive.
