Circalgae

Problem statement

Valorize the widely produced, but under-exploited algal biomass into high value added ingredients for the feed, food and cosmetic applications.

Executive summary

The Phycocolloid and microalgae industry across EU only uses 15-30% of algae, while the remaining 65-70% is wasted so with this in researchers and Industrial partners have formed the CIRCALGAE (CIRCular valorisation of industrial ALGAE waste streams into high-value products) project to optimize production of algae based on season, location, cultivation condition to develop new more sustainable biorefineries.

Value chain description

CIRCALGAE will boost the blue bioeconomy by applying an integrated biorefinery concept to valorise the massively produced (over 36 Mt of algae biomass annual world production) and vastly underexploited algae industrial waste streams (which can add up to 95% of the initial biomass) from the main existing sources to date: the phycolloid production from macroalgae and protein/lipid microalgae industries. CIRCALGAE’s simple, water-based technologies, will transform these waste streams into value-added ingredients to be used in specific texturized vegan foods, health-promoting food ingredients, protein rich feed, and cosmetic formulations incorporating texturizing or highly bioactive ingredients for topical use
