MULTIPLY will develop 10 innovative algae-based products across the food, feed, cosmetics, biomaterials, and lubricants sectors, using biomass from Arthrospira, Tetraselmis, Nannochloropsis, Chromochloris zofingiensis, and diatoms. These include natural colorants for food applications, functional protein-rich ingredients for feed and food, fatty acid esters for lubricants and cosmetics, active and multifunctional bio-based coatings for packaging, compostable bioplastics, and bio-polyesters derived from algal oils and starch. Each product will be validated by industrial partners to ensure cost-effectiveness, environmental sustainability, and market readiness, paving the way for large-scale deployment of microalgae-based solutions in Europe.
